Career Summary
Biography
DR MATT DUN - BIOMEDICAL SCIENTIST AND 'DIPG DAD'
Dr Matt Dun is a National Health and Medical Research Council (NHMRC) Emerging Leadership Fellow (2020-2024) and a Defeat DIPG Chadtough New Investigator (2020-2021). He is currently Senior Lecturer at the University of Newcastle, Australia. His position and research has been supported by state and/or national funding bodies continuously since 2012, as well as supplemented by philanthropic and industry contributors throughout.
Decorated by more than 20 national and international awards, Matt achieved his PhD at The University of Newcastle and Hunter Medical Research Institute by publication in 2012. Soon after, he refocused his research from reproductive cell biology and biochemistry, to the fields of medical biochemistry, cancer cell biology and his now specialty - proteomics and intermolecular interactions.
International post-doctoral training (2013/2014) with field-leading experts in phosphoproteomics (Prof Larsen at SDU) and leukaemia signalling (Prof Cools at KU Leuven), set Matt on a path to establishing his own research laboratory. With his research vision strongly aligned with the University of Newcastle’s Priority Research Centre for Cancer Research, Innovation and Translation (PRC CARiT), Matt formed the Cancer Signalling Research Group (CSRG) based at the University of Newcastle (UON). This was facilitated (and later enhanced) via his securement of successive Cancer Institute NSW Early Career Fellowships (2014-2016, 2017-2019), NHMRC Investigator Grant (2020-2025), Defeat DIPG Chadtough New Investigator Grant (2020-2021) and successful Cancer Institute NSW and NHMRC Equipment Grants to establish a high-resolution mass spectrometry platform at the UON.
Recently bestowed as the NSW Premier’s Award for Outstanding Cancer Research Fellow of 2019, Dr Matt Dun guides the CSRG team of staff and students in fields of leukaemic, colonic, and brain cancer research. The group employ sophisticated phosphoproteomic techniques to characterise the cellular signalling pathways dysregulated by the genetics individualities of a patient’s cancer. This profiling strategy attempts to identify novel treatment targets and drug combinations to improve survival.A member of the Australian & New Zealand Children’s Haematology/Oncology Group (ANZCHOG) and the Australian Leukaemia and Lymphoma Group (ALLG), Matt’s latest collaboration with local investigators (Verrills, Enjeti, Lee) tests a new therapy for acute myeloid leukaemia (AML), and aims to identify the influences of the epigenome of the clonal evolution of AM; both awarded NHMRC Ideas Grant funding from 2020.
Although initially focused on blood cancers, Matt’s research faced an unexpected shift in focus in 2018, when his then 2-year-old daughter Josephine, was diagnosed with Grade IV diffuse intrinsic pontine glioma (DIPG). Also known as diffuse midline glioma (DMG), Matt was struck by the lack of scientific knowledge regarding the pathophysiology of the disease, and by the stark absence of treatments for DIPG patients - so he set about creating his own program of DIPG research. Guided by those at the forefront of worldwide DIPG research (Monje, Nazarian, Mueller), and self-funded (thanks to the establishment of his own charity ‘RUN DIPG’), Matt’s endeavours have led to the first, high-resolution, quantitative proteomic analysis of the disease.
The esteem of Matt’s DIPG work was recently highlighted via his invited presentation at the International DIPG Symposium, August 2019 and the award of NHMRC Investigator and Defeat DIPG Chadtough New Investigator fellowships. In 2020, Matt has joined (by invitation) the 'Preclinical Working Group' of the Pacific Neuro Oncology Consortium (PNOC) known as 'DMG-ACT'. Basic and discovery scientists worldwide share their latest preclinical DIPG data with clinical collaborators whom lead DIPG/DMG clinical trials - greatly enhancing opportunities for research impact and translation to improved patient outcomes.
Dr Dun has 95 refereed journal articles and book chapters, with an accompanying 970 citations and H-index of 17. In his short career, Matt has been a Chief Investigator on three NHMRC grants including CIA of the Investigator Grant fellowship scheme commencing 2020. Matt’s total research income since PhD award in 2012 is >$8.3 million. Matt is an invited editor to Frontiers of Oncology and is a Peer Review panelist for the NHMRC Investigator Grants 2019 - .
Also a member of the Hunter Cancer Research Alliance (HCRA), the Brain Foundation, the Australasian Proteomics Society and the Australian Society for Medical Research (the latter of which he was a Director 2015-2017), Matt is a well-respected biomedical scientist. He is a dedicated role model to his colleagues, his four staff and the 7 PhD students presently under his supervision. Matt’s latest endeavours can be found across social media platforms (@MattDun17) where he is an active scientific advocate to research, clinical and lay communities alike.

Background: Circulating tumour DNA (ctDNA) has emerged as an excellent candidate for the future of liquid biopsies for many cancers. There has been growing interest in blood-based liquid biopsy because of the potential of ctDNA to produce a noninvasive test that can be used for: the diagnosis of colorectal cancer, monitoring therapy response, and providing information on overall prognosis. The aim of this review was to collate and explore the current evidence regarding ctDNA as a screening tool for colorectal cancer (CRC). Methods: A systematic review of published articles in English over the past 20 y was performed using Medline, Embase, and Cochrane databases on May 23, 2017. After a full-text review, a total of 69 studies were included. Two assessment tools were used to review and compare the methodological quality of these studies. Results: Among the 69 studies included, 17 studies reviewed total cfDNA, whereas six studies looked at the DNA integrity index and 15 focused on ctDNA. There were a total of 40 studies that reviewed methylated cfDNA with 19 of these focussing specifically on SEPT9. Conclusions: The results of this review indicate that methylated epigenetic ctDNA markers are perhaps the most promising candidates for a blood-based CRC-screening modality using cell-free (cf) DNA. Methylated cfDNA appears to be less specific for CRC compared to ctDNA; however, they have demonstrated good sensitivity for early-stage CRC. Further research is required to determine which methylated cfDNA markers are the most accurate when applied to large cohorts of patients. In addition, reliable comparison of results across multiple studies would benefit from standardization of methodology for DNA extraction and PCR techniques in the future.

[more] Copyright © 2018 Endocrine Society The central characteristic of uterine fibroids is excessive deposition of extracellular matrix (ECM), which contributes to fibroid growth and bulk-type symptoms. Despite this, very little is known about patterns of ECM protein expression in fibroids and whether these are influenced by the most common genetic anomalies, which relate to MED12. We performed extensive genetic and proteomic analyses of clinically annotated fibroids and adjacent normal myometrium to identify the composition and expression patterns of ECM proteins in MED12 mutation-positive and mutation-negative uterine fibroids. Genetic sequencing of tissue samples revealed MED12 alterations in 39 of 65 fibroids (60%) from 14 patients. Using isobaric tagged-based quantitative mass spectrometry on three selected patients (n = 9 fibroids), we observed a common set of upregulated (.1.5-fold) and downregulated (,0.66-fold) proteins in small, medium, and large fibroid samples of annotated MED12 status. These two sets of upregulated and downregulated proteins were the same in all patients, regardless of variations in fibroid size and MED12 status. We then focused on one of the significant upregulated ECM proteins and confirmed the differential expression of periostin using western blotting and immunohistochemical analysis. Our study defined the proteome of uterine fibroids and identified that increased ECM protein expression, in particular periostin, is a hallmark of uterine fibroids regardless of MED12 mutation status. This study sets the foundation for further investigations to analyze the mechanisms regulating ECM overexpression and the functional role of upregulated ECM proteins in leiomyogenesis.

All rights reserved. Mutations in the interleukin-7 receptor (IL7R) or the Janus kinase 3 (JAK3) kinase occur frequently in T-cell acute lymphoblastic leukemia (T-ALL) and both are able to drive cellular transformation and the development of T-ALL in mouse models. However, the signal transduction pathways downstream of JAK3 mutations remain poorly characterized. Here we describe the phosphoproteome downstream of the JAK3(L857Q)/(M511I) activating mutations in transformed Ba/F3 lymphocyte cells. Signaling pathways regulated by JAK3 mutants were assessed following acute inhibition of JAK1/JAK3 using the JAK kinase inhibitors ruxolitinib or tofacitinib. Comprehensive network interrogation using the phosphoproteomic signatures identified significant changes in pathways regulating cell cycle, translation initiation, mitogen-activated protein kinase and phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K)/AKT signaling, RNA metabolism, as well as epigenetic and apoptotic processes. Key regulatory proteins within pathways that showed altered phosphorylation following JAK inhibition were targeted using selumetinib and trametinib (MEK), buparlisib (PI3K) and ABT-199 (BCL2), and found to be synergistic in combination with JAK kinase inhibitors in primary T-ALL samples harboring JAK3 mutations. These data provide the first detailed molecular characterization of the downstream signaling pathways regulated by JAK3 mutations and provide further understanding into the oncogenic processes regulated by constitutive kinase activation aiding in the development of improved combinatorial treatment regimens.

Immune activation can alter the activity of adrenal chromaffin cells. The effect of immune activation by lipopolysaccharide (LPS) on the regulation of tyrosine hydroxylase (TH) in the adrenal medulla in vivo was determined between 1 day and 6 months after LPS injection. The plasma levels of eleven cytokines were reduced 1 day after LPS injection, whereas the level for interleukin-10 was increased. The levels of all cytokines remained at control levels until 6 months when the levels of interleukin-6 and -4 were increased. One day after LPS injection, there was a decrease in TH-specific activity that may be due to decreased phosphorylation of serine 31 and 40. This decreased phosphorylation of serine 31 and 40 may be due to an increased activation of the protein phosphatase PP2A. One week after LPS injection, there was increased TH protein and increased phosphorylation of serine 40 that this was not accompanied by an increase in TH-specific activity. All TH parameters measured returned to basal levels between 1 month and 3 months. Six months after injection there was an increase in TH protein. This was associated with increased levels of the extracellular regulated kinase isoforms 1 and 2. This work shows that a single inflammatory event has the capacity to generate both short-term and long-term changes in TH regulation in the adrenal medulla of the adult animal. J. Cell.

Introduction: Genomic and transcriptomic profiling of tumours has revolutionised our understanding of cancer. However, the majority of tumours possess multiple mutations, and determining which oncogene, or even which pathway, to target is difficult. Proteomics is emerging as a powerful approach to identify the functionally important pathways driving these cancers, and how they can be targeted therapeutically. Areas covered: The authors provide a technical overview of mass spectrometry based approaches for proteomic profiling, and review the current and emerging strategies available for the identification of dysregulated networks, pathways, and drug targets in cancer cells, with a key focus on the ability to profile cancer kinomes. The potential applications of mass spectrometry in the clinic are also highlighted. Expert opinion: The addition of proteomic information to genomic platforms¿¿proteogenomics¿¿is providing unparalleled insight in cancer cell biology. Application of improved mass spectrometry technology and methodology, in particular the ability to analyse post-translational modifications (the PTMome), is providing a more complete picture of the dysregulated networks in cancer, and uncovering novel therapeutic targets. While the application of proteomics to discovery research will continue to rise, improved workflow standardisation and reproducibility is required before mass spectrometry can enter routine clinical use.

Post-testicular sperm maturation and storage within the epididymis is a key determinant of gamete quality and fertilization competence. Here we demonstrate that mouse spermatozoa possess a complex small non-protein-coding RNA (sRNA) profile, the composition of which is markedly influenced by their epididymal transit. Thus, although microRNAs (miRNAs) are highly represented in the spermatozoa of the proximal epididymis, this sRNA class is largely diminished in mature spermatozoa of the distal epididymis. Coincident with this, a substantial enrichment in Piwi-interacting RNA (piRNA) abundance in cauda spermatozoa was detected. Further, features of cauda piRNAs, including; predominantly 29¿31 nts in length; preference for uracil at their 5' terminus; no adenine enrichment at piRNA nt 10, and; predominantly mapping to intergenic regions of the mouse genome, indicate that these piRNAs are generated by the PIWIL1-directed primary piRNA production pathway. Accordingly, PIWIL1 was detected via immunoblotting and mass spectrometry in epididymal spermatozoa. These data provide insight into the complexity and dynamic nature of the sRNA profile of spermatozoa and raise the intriguing prospect that piRNAs are generated in situ in maturing spermatozoa. Such information is of particular interest in view of the potential role for paternal sRNAs in influencing conception, embryo development and intergenerational inheritance.

Purpose: Protein phosphatase 2A (PP2A) is a family of serine/threonine phosphatases that regulate multiple cellular signalling pathways involved in proliferation, survival and apoptosis. PP2A inhibition occurs in many cancers and is considered a tumour suppressor. Deletion/downregulation of PP2A genes has been observed in breast tumours, but the functional role of PP2A subunit loss in breast cancer has not been investigated. Methods: PP2A subunit expression was examined by immunohistochemistry in human breast tumours, and by qPCR and immunoblotting in breast cancer cell lines. PP2A subunits were inhibited by shRNA, and mutant PP2A genes overexpressed, in MCF10A and MCF7 cells, and growth and signalling in standard and three-dimensional cultures were assessed. Results: Expression of PP2A-Aa, PP2A-Ba and PP2A-B'a subunits was significantly lower in primary human breast tumours and lymph node metastases, compared to normal mammary tissue. PP2A-Aa and the regulatory subunits PP2A-Ba, -Bd and -B'¿ were also reduced in breast cancer cell lines compared to normal mammary epithelial cells. Functionally, shRNA-mediated knockdown of PP2A-Ba, -B'a and -B'¿, but not PP2A-Aa, induced hyper-proliferation and large multilobular acini in MCF10A 3D cultures, characterised by activation of ERK. Expression of a breast cancer-associated PP2A-A mutant, PP2A-Aa-E64G, which inhibits binding of regulatory subunits to the PP2A core, induced a similar hyper-proliferative phenotype. Knockdown of PP2A-Ba also induced hyper-proliferation in MCF7 breast cancer cells. Conclusion: These results suggest that loss of specific PP2A regulatory subunits is functionally important in breast tumourigenesis, and support strategies to enhance PP2A activity as a therapeutic approach in breast cancer.

AAL(S), the chiral deoxy analog of the FDA approved drug FTY720, has been shown to inhibit proliferation and apoptosis in several cancer cell lines. It has been suggested that it does this by activating protein phosphatase 2A (PP2A). Here we report the synthesis of new cytotoxic analogs of AAL(S) and the evaluation of their cytotoxicity in two myeloid cell lines, one of which is sensitive to PP2A activation. We show that these analogs activate PP2A in these cells supporting the suggested mechanism for their cytotoxic properties. Our findings identify key structural motifs required for anti-cancer effects.

[more] Constitutive activation of the receptor tyrosine kinase Fms-like tyrosine kinase 3 (FLT3), via co-expression of its ligand or by genetic mutation, is common in acute myeloid leukemia (AML). In this study we show that FLT3 activation inhibits the activity of the tumor suppressor, protein phosphatase 2A (PP2A). Using BaF3 cells transduced with wildtype or mutant FLT3, we show that FLT3-induced PP2A inhibition sensitizes cells to the pharmacological PP2A activators, FTY720 and AAL(S). FTY720 and AAL(S) induced cell death and inhibited colony formation of FLT3 activated cells. Furthermore, PP2A activators reduced the phosphorylation of ERK and AKT, downstream targets shared by both FLT3 and PP2A, in FLT3/ITD+ BaF3 and MV4-11 cell lines. PP2A activity was lower in primary human bone marrow derived AML blasts compared to normal bone marrow, with blasts from FLT3-ITD patients displaying lower PP2A activity than WT-FLT3 blasts. Reduced PP2A activity was associated with hyperphosphorylation of the PP2A catalytic subunit, and reduced expression of PP2A structural and regulatory subunits. AML patient blasts were also sensitive to cell death induced by FTY720 and AAL(S), but these compounds had minimal effect on normal CD34+ bone marrow derived monocytes. Finally, PP2A activating compounds displayed synergistic effects when used in combination with tyrosine kinase inhibitors in FLT3-ITD+ cells. A combination of Sorafenib and FTY720 was also synergistic in the presence of a protective stromal microenvironment. Thus combining a PP2A activating compound and a FLT3 inhibitor may be a novel therapeutic approach for treating AML.

Brain metastases are a devastating consequence of cancer and currently there are no specific biomarkers or therapeutic targets for risk prediction, diagnosis, and treatment. Here the proteome of the brain metastatic breast cancer cell line 231-BR has been compared with that of the parental cell line MDA-MB-231, which is also metastatic but has no organ selectivity. Using SILAC and nanoLC-MS/MS, 1957 proteins were identified in reciprocal labeling experiments and 1584 were quantified in the two cell lines. A total of 152 proteins were confidently determined to be up- or down-regulated by more than twofold in 231-BR. Of note, 112/152 proteins were decreased as compared with only 40/152 that were increased, suggesting that down-regulation of specific proteins is an important part of the mechanism underlying the ability of breast cancer cells to metastasize to the brain. When matched against transcriptomic data, 43% of individual protein changes were associated with corresponding changes in mRNA, indicating that the transcript level is a limited predictor of protein level. In addition, differential miRNA analyses showed that most miRNA changes in 231-BR were up- (36/45) as compared with down-regulations (9/45). Pathway analysis revealed that proteome changes were mostly related to cell signaling and cell cycle, metabolism and extracellular matrix remodeling. The major protein changes in 231-BR were confirmed by parallel reaction monitoring mass spectrometry and consisted in increases (by more than fivefold) in the matrix metalloproteinase-1, ephrin-B1, stomatin, myc target-1, and decreases (by more than 10-fold) in transglutaminase-2, the S100 calcium-binding protein A4, and L-plastin. The clinicopathological significance of these major proteomic changes to predict the occurrence of brain metastases, and their potential value as therapeutic targets, warrants further investigation.

Proteogenomics, or the integration of proteomics with genomics and transcriptomics, is emerging as the next step towards a unified understanding of cellular functions. Looking globally and simultaneously at gene structure, RNA expression, protein synthesis and posttranslational modifications have become technically feasible and offer a new perspective to molecular processes. Recent publications have highlighted the value of proteogenomics in oncology for defining the molecular signature of human tumors, and translation to other areas of biomedicine and life sciences is anticipated. This minireview will discuss recent developments, challenges and perspectives in proteogenomics.

The functional maturation of mammalian spermatozoa is accomplished as the cells descend through the highly specialized microenvironment of the epididymis. This dynamic environment is, in turn, created by the combined secretory and absorptive activity of the surrounding epithelium and displays an extraordinary level of regionalization. Although the regulatory network responsible for spatial coordination of epididymal function remains unclear, recent evidence has highlighted a novel role for the RNA interference pathway. Indeed, as noncanonical regulators of gene expression, small noncoding RNAs have emerged as key elements of the circuitry involved in regulating epididymal function and hence sperm maturation. Herein we have employed next generation sequencing technology to profile the genome-wide miRNA signatures of mouse epididymal cells and characterize segmental patterns of expression. An impressive profile of some 370 miRNAs were detected in the mouse epididymis, with a subset of these specifically identified within the epithelial cells that line the tubule (218). A majority of the latter miRNAs (75%) were detected at equivalent levels along the entire length of the mouse epididymis. We did however identify a small cohort of miRNAs that displayed highly regionalized patterns of expression, including miR-204-5p and miR-196b-5p, which were down- and up-regulated by approximately 39- and 45-fold between the caput/caudal regions, respectively. In addition we identified 79 miRNAs (representing ~ 21% of all miRNAs) as displaying conserved expression within all regions of the mouse, rat and human epididymal tissue. These included 8/14 members of let-7 family of miRNAs that have been widely implicated in the control of androgen signaling and the repression of cell proliferation and oncogenic pathways. Overall these data provide novel insights into the sophistication of the miRNA network that regulates the function of the male reproductive tract.

Mouse knockout models and in vitro studies have suggested that Fat1 influences cell polarity and motility. Fat1 is also an upstream regulator of the Hippo pathway, at least in lower vertebrates, and hence may play a role in growth control. In previous work we have established that FAT1 cadherin is initially cleaved by proprotein convertases to form a noncovalently linked heterodimer prior to expression on the cell surface. Such processing was not a requirement for cell surface expression, since melanoma cells expressed both unprocessed FAT1 and the heterodimer on the cell surface. Here we further establish that the site 1 (S1) cleavage step to promote FAT1 heterodimerisation is catalysed by furin and we identify the cleavage site utilised. For a number of other transmembrane receptors that undergo heterodimerisation the S1 processing step is thought to occur constitutively but the functional significance of heterodimerisation has been controversial. It has also been generally unclear as to the significance of receptor heterodimerisation with respect to subsequent post-translational proteolysis that often occurs in transmembrane proteins. Exploiting the partial deficiency of FAT1 processing in melanoma cells together with furin-deficient LoVo cells, we manipulated furin expression to demonstrate that only the heterodimer form of FAT1 is subject to cleavage and subsequent release of the extracellular domain. This work establishes S1-processing as a clear functional prerequisite for ectodomain shedding of FAT1 with general implications for the shedding of other transmembrane receptors. © 2014.

They might also have anti-inflammatory properties, but the underpinning mechanisms remain poorly understood. Recently, a direct interaction between formoterol and protein phosphatase 2A (PP2A) has been described in¿vitro. Objective: We sought to elucidate the molecular mechanisms by which ß-agonists exert anti-inflammatory effects in allergen-driven and rhinovirus 1B-exacerbated allergic airways disease (AAD). Methods: Mice were sensitized and then challenged with house dust mite to induce AAD while receiving treatment with salmeterol, formoterol, or salbutamol. Mice were also infected with rhinovirus 1B to exacerbate lung inflammation and therapeutically administered salmeterol, dexamethasone, or the PP2A-activating drug (S)-2-amino-4-(4-[heptyloxy]phenyl)-2-methylbutan-1-ol (AAL[S]). Results: Systemic or intranasal administration of salmeterol protected against the development of allergen- and rhinovirus-induced airway hyperreactivity and decreased eosinophil recruitment to the lungs as effectively as dexamethasone. Formoterol and salbutamol also showed anti-inflammatory properties. Salmeterol, but not dexamethasone, increased PP2A activity, which reduced CCL11, CCL20, and CXCL2 expression and reduced levels of phosphorylated extracellular signal-regulated kinase 1 and active nuclear factor ¿B subunits in the lungs. The anti-inflammatory effect of salmeterol was blocked by targeting the catalytic subunit of PP2A with small RNA interference. Conversely, increasing PP2A activity with AAL(S) abolished rhinovirus-induced airway hyperreactivity, eosinophil influx, and CCL11, CCL20, and CXCL2 expression. Salmeterol also directly activated immunoprecipitated PP2A in¿vitro isolated from human airway epithelial cells. Conclusions: Salmeterol exerts anti-inflammatory effects by increasing PP2A activity in AAD and rhinovirus-induced lung inflammation, which might potentially account for some of its clinical benefits. © 2013 American Academy of Allergy, Asthma & Immunology.

Characterisation of low Δ9-tetrahydrocannabinol containing medicinal cannabis for the treatment of acute myeloid leukaemia. <span style="font-size:12.0pt;font-family:'Arial',sans-serif;">Acute Myeloid Leukaemia (AML) carries a 5-year survival rate of 24%. Current treatments include high dose chemotherapy and bone marrow transplantation; however development of treatment resistance and relapse is common. Cannabis has been used for thousands of years as a traditional medicine and was introduced into western medicine in the nineteenth century. More recently, research into medicinal cannabis has focused on traditional high-THC containing products. Low-THC cannabis is legally defined as having less than 1% Δ9-THC and therefore, does not have the phsychotropic effects associated with tradtional cannabis. The aims of this research was to determine whether low-THC cannabis extracts were effective at reducing the survival of AML cells that are sensitive to new precision medicines and AML cells that have formed resistance to these therapies whilst determining whether low-THC cannabis effects the survival of normal healthy cells of the immune system. Two AML cell lines harbouring recurring genetic mutations were used and both show sensitivity to our crude low-THC cannabis extracts. To determine which cannabinoid or unknown chemicals was responsible for the cytotoxic effects we showed, High Performance Liquid Chromatography with Ultraviolet visible light detection (HPLC-UV Vis) was used. During this investigation we have optimised a HPLC-UV Vis technique that resolves thirteen common cannabinoids found in cannabis extracts and used this to analyse what was present in our low-THC containing cannabis extracts. Using various extraction techniques coupled to cytotoxic analysis and HPLC-UV, we have discovered that cannabidiol (CBD) and cannabichromene (CBC) are potentially invovled at inducing cell death of AML cells. Additionally, we have identified an unknown compound whose concentration in each of the extracts reflects the cytotoxicity seen. Future research is still necessary to analyse the unknown compounds and individual activity of compounds, but the research described herein reveals that low-THC containing cannabis is effective at killing AML cells.</span> |

Targeting Oxidative Stress for the Improved Treatment of Acute Myeloid Leukaemia <p style="text-align:justify;line-height:150%;"><span style="font-family:Arial,Helvetica,sans-serif;font-size:small;">Treatment of acute myeloid leukaemia (AML) has remained unchanged over the last 35 years, with standard-of-care chemotherapeutics causing significant side effects and treatment induced death. AML patients often develop resistance to therapies, causing the formation of an even more aggressive untreatable disease that rapidly leads to death. Interest in reactive oxygen species has grown as studies have revealed that high levels of Reactive oxygen species (ROS) are seen in almost all cancer types, including AML. Despite this, the physiological and pathophysiological role that ROS plays in AML has widely remained unknown. It is a possibility that the altered redox environment initiated by the processes of cellular transformation may in fact drive leukaemogenesis. We believe this is through oxidative modifications to crucial regulators of cellular signalling, as well as acquired insults to nucleic acids and lipids, driving increased growth, survival and genomic instability. The altered redox environment may in fact be the cause for the development of drug resistance that is commonly seen during the treatment of an AML patient. These data raise the intriguing possibility of whether ROS may be a novel target for the treatment of AML.</span></p><p style="text-align:justify;line-height:150%;"><span style="font-family:Arial,Helvetica,sans-serif;font-size:small;"><span style="font-size:small;font-family:Arial,Helvetica,sans-serif;">The customary paradigm for the treatment of cancer is to induce ROS formation so that it causes irreversible oxidative damage. Our laboratory has shown that the most common molecular driver of AML, the FLT3 </span><span style="text-decoration:underline;">I</span><span style="font-size:small;font-family:Arial,Helvetica,sans-serif;">nternal </span><span style="text-decoration:underline;">T</span><span style="font-size:small;font-family:Arial,Helvetica,sans-serif;">andem </span><span style="text-decoration:underline;">D</span><span style="font-size:small;font-family:Arial,Helvetica,sans-serif;">uplication (ITD) mutation, leads to cells that produce very high levels of ROS that modify the bone marrow redox microenvironment. Further, using novel and sophisticated proteomics techniques we have shown that AML patients harbouring FLT-ITD+ mutations express proteins showing oxidation of catalytic cysteines in a number of key tumour suppressor proteins such as the protein tyrosine phosphatases (PTPs) which renders them inactive. These novel data may explain the hyperactive activated growth and survival signalling pathways that characterise this subtype of AML. </span></span></p><p style="text-align:justify;line-height:150%;"><span style="font-family:Arial,Helvetica,sans-serif;font-size:small;">The hypothesis for my project is that if we reduce intracellular ROS we may reduce the oxidation of a number of key tumour suppressor proteins we have shown to be inactivated in FLT3-ITD+ AMLs. Through the specific inhibition of ROS production using new FLT3 targeted therapies we will not only inhibit the oncogene responsible for transformation but we will reactivate the negative regulators of the FLT3 pathway, whilst reducing oxidative DNA damage that may help us to overcome issues with resistance and therefore reduce relapse rates and fatalities. </span></p><div><p style="text-align:justify;line-height:150%;"><span style="font-family:Arial,Helvetica,sans-serif;font-size:small;">In the studies described herein, we show that by inhibiting NOX2 we inhibit ROS production. When NOX2 inhibition is combined with FLT3 inhibition, we can induce synergistic cytotoxicity to FLT3-ITD+ AML cells when grown and treated in a model of the bone marrow characterised by low oxygen tension. We also present exciting preliminary mechanistic data showing that the FLT3 regulating PTPs, SHP-1 and DEP-1, are oxidised by ROS produced by NOX2, and that reduced oxidative stress through NOX2 inhibition increased PTP activity by reduced catalytic cysteine oxidation and increased PTP protein expression. </span></p><p style="text-align:justify;line-height:150%;"><span style="font-family:Arial,Helvetica,sans-serif;font-size:small;">The results of my project show NADPH oxidase as a potent source of reactive oxygen species that is responsible for high levels of oxidative stress seen in the most commonly occurring genetic mutation in AML – FLT3-ITD. ROS produced by the NADPH oxidase-2 complex causes increased DNA damage increasing the genomic instability of these cells and potentially influences the common resistance to therapies that we see. Additionally, my thesis sets the ground-work for a novel treatment paradigm that reduced oxidative stress, which leads to reactivation of intrinsic defence systems that work in cooperation with targeted therapies to synergistically kill AML cells. Finally, the impact of targeting the redox microenvironment in AML and the potential for modulating ROS production for the treatment of AML are discussed, along with the limitations and future directions of this study.</span></p></div><span style="font-size:12.0pt;line-height:150%;font-family:'Times New Roman',serif;"><br clear="all" style="page-break-before:always;" /></span> |

Prostate cancer: Quantification of proNGF by targeted proteomics Background. Prostate cancer (PCa) is one of the most prevalent cancers in Australia. The PCa serum biomarker prostate specific antigen (PSA) is used for screening, diagnosis and prognosis, but increasing evidence indicates that PSA testing has serious limitations. Not only does it lack specificity (with false positive and negative detections), but it also fails in identifying the most aggressive forms of PCa that require treatment as compared to the indolent forms of the disease. There is therefore an urgent need for new biomarkers to improve the diagnosis and prognosis of PCa. <br />Preliminary data from our lab have identified the precursor of nerve growth factor (proNGF) as a new potential serum biomarker for PCa. ProNGF expression is increased in cancer cells and positively correlates with PCa aggressiveness. In addition, PCa cells secrete proNGF, and by ELISA increased concentration of proNGF were found in the serum of PCa patients, in particular in case of aggressive tumours. These data suggest that proNGF could be a novel serum biomarker for diagnosis and prognosis of PCa. <br />Aims. This project is focused on developing a targeted proteomic assay (in parallel reaction monitoring - PRM) to reliably quantify proNGF in serum samples. The assay will subsequently be applied for the analysis of PCa serum samples. <br />Methods. After in silico trypsin digestion, two tryptic peptides unique to proNGF were selected with molecular mass and charge appropriate for detection in mass spectrometry. We have obtained the corresponding stable isotope labelled (SIL) peptides and we have established all experimental conditions for their detection in the serum and quantification in PRM mass spectrometry. In particular, we have analysed a series of PCa samples (n=40) of different grade and a series of benign prostatic hyperplasia (BPH, n=20). The results were compared with data obtained by ELISA for proNGF in the same samples. <br />Results. 1. An optimised PRM quantification approach was achieved by analysing twoproNGF SIL peptides LQHSLDTALR and SAPAAAIAAR (by direct injection and in complex serum background). 2. Standard curves for both proNGF SIL peptides in complex serum background were generated and performed to normalise inter-run variability of the mass spectrometer. 3. The average quantity of proNGF endogenous peptide LQHSLDTALR in serum samples was 0.021 ± 0.050 ng/mL, whereas proNGF endogenous peptide SAPAAAIAAR was undetectable. 4. No significant difference of proNGF peptide LQHSLDTALR quantity was found either between BPH and PCa cancer or across BPH group, low-risk PCa (Gleason 6) and high-risk PCa (Gleason 8 & 9). 5. The correlation factor (r) between PRM data for peptide LQHSLDTALR and the ELISA for proNGF was 0.21, indicating a limited correspondence between data obtained by the two methods. <br />Conclusion. We have developed a PRM based assay for quantifying proNGF in biological samples with a very good specificity/sensitivity (picogram/mL level). However, its use to quantify proNGF in the serum of PCa patients needs further improvements and in particular further optimisation in sample preparation, such as albumin depletion and deglycosylation. Such a PRM assay for proNGF could find biomedical applications beyond PCa, as proNGF has recently been reported to be increased in the cerebrospinal fluid of patients with neurodegenerative disease. <br />6 |

Development of a sensitive, robust and quantitative mass spectrometry assay for the measurement of activated signalling pathways in human breast cancers <p style="text-align:justify;text-justify:inter-ideograph;line-height:150%;"><span lang="EN-US" style="color:windowtext;">Breast cancer is a major national and global health concern. While the overall survival for breast cancer has significantly improved over the past decades, outcomes for patients with triple negative (TNBC) or Luminal B subtype tumuors remains poor. Recent studies have shown that some TNBCs display inactivation of key DNA damage repair (DDR) pathways which renders them hypersensitive to specific DNA damaging chemotherapy. Whether other breast cancer subtypes also have altered DDR pathways is not known, in part because an effective tool for quantifying the activity of DDR pathways is not available. Therefore, we aimed to develop a robust and sensitive assay to quantitate the activity of DDR pathways in breast cancer.</span><span style="color:windowtext;"> Recent studies indicate that </span><span style="color:windowtext;">a targeted proteomics approach, utilising </span><span style="color:windowtext;">quantitative mass spectrometry-based </span><span style="color:windowtext;">parallel reaction monitoring (PRM), may be a useful technique for identification and quantification of such pathways. PRM is a highly selective and specific method for targeted peptide quantification, including peptides with post-translational modifications such as phosphorylation. It is beginning to be implemented for the quantitative study of changes in protein components within cancer cells. Given that cancer associated signalling pathways are regulated by phosphorylation of key protein mediators, we hypothesized that</span><span style="color:windowtext;"> the development of</span><span style="color:windowtext;"> a multiplexed PRM assay for quantitation of key phosphoproteins involved in activated signalling pathways could be a powerful tool for the identification of activated, and potentially ‘druggable’ pathways in human breast tumours. </span></p><p style="text-align:justify;text-justify:inter-ideograph;line-height:150%;"><span>Sample preparation is the crucial starting point to obtain high-quality mass spectrometry data, therefore a major focus of this thesis was to determine the optimal sample preparation procedure for PRM-based quantitation of phospho-peptides. To do this,</span><span style="color:windowtext;"> the human breast cancer cell line, </span><span lang="EN-US" style="color:windowtext;">BT474, was </span><span style="color:windowtext;">treated +/- bleomycin to induce double stranded DNA breaks (DSBs) and activate DSB repair pathways. Proteins were extracted in either a sodium carbonate buffer or via the commercially available </span><span lang="EN-US">ProteaseMax<sup>TM</sup></span><span style="color:windowtext;"> kit, and enzymatically digested into peptides using trypsin and lysozyme C, and identified by liquid chromatography tandem mass spectrometry (LC-MS/MS). Analysis of the identified peptides demonstrated </span><span lang="EN-US">enhanced tryptic/Lys C digestion efficiency with the sodium carbonate method, and as such this was used for all subsequent experiments. However, phosphorylated peptides only constituted ~1% of the total peptides identified, and the peak intensity for most phospho-peptides was low, making accurate quantitation difficult. Recent studies have shown <a name="OLE_LINK41">enrichment of phosphopeptides</a> using titanium dioxide chromatography (TiO2) significantly increases the number of phosphoproteins identified in discovery MS projects. Whether phospho-peptide enrichment is required for targeted PRM MS approaches however has not been determined. Therefore, a direct comparison of non-enriched versus phospho-peptide enrichment using a range of TiO2 procedures were performed in the BT474 cells. This resulted in high abundance of non-modified peptides in the non-enriched and flow through lysates, while the majority of phosphopeptides were found in TiO2 eluates. The enrichment enabled improved quantitation of specific phosphopeptides by PRM, and thus confirmed that enrichment with at least one TiO2 step was required for quantitative detection of phosphopeptides. </span></p><p style="text-align:justify;text-justify:inter-ideograph;line-height:150%;"><span lang="EN-US">This optimized procedure was then used to quantitate key phosphoproteins involved in growth, survival and DNA damage repair pathways in breast cancer. </span><span style="color:windowtext;">As a positive control we analysed H2AX, a key marker of DSBs, and as expected found increased phosphorylation of pSer139-H2AX in response to bleomycin. We further found increased phosphorylation of </span><span lang="EN-US" style="color:windowtext;">Protein Kinase B (AKT; Thr307 and Ser473), </span><span style="color:windowtext;">checkpoint kinase 2 (CHK2) at Thr386, and the ataxia-telangiectasia mutated (ATM) protein (double phosphorylation at Y175 and S179). In contrast H2AX doubly phosphorylated at S139/Y140, pThr68-CHK2 and pSer367-ATM was reduced. This provides novel insight into the cellular response to DSBs. Importantly, t</span><span lang="EN-US" style="color:windowtext;">his analysis was achieved from average 2 µg of peptides, therefore we believe this assay will be useful for primary patient tissues and hence may be a powerful approach for identifying activated and druggable pathways in human breast tumuors.</span></p> |

The Role of Reduced Protein Phosphatase 2A Subunit, PPP2R2A (B55α), Expression in Breast Cancer. <p style="margin-bottom:0cm;margin-bottom:.0001pt;line-height:150%;"><span style="font-size:12.0pt;line-height:150%;font-family:'Times New Roman',serif;">Breast Cancer is a disease of global concern, with current treatments lacking selectivity and not showing a response in many patients. Patients with luminal-B like breast cancers in particular have shown reduced sensitivity to endocrine therapies, and have a more aggressive phenotype similar to Triple Negative breast tumours and worse prognosis than luminal-A like breast tumours. A marker and potential therapeutic target was thus need to distinguish these particular patients, as current methods of classification have been shown to be ineffective, especially in distinguishing between luminal-A and B tumours. Recent studies have shown that reduced expression of the <em>PPP2R2A</em> gene, encoding the B55a subunit of Protein Phosphatase 2a (PP2A), may be such a marker, with highly reduced expression in a majority of luminal-B tumours studied. Reduced expression of this subunit has been found to impair the DNA damage Homologous Recombination (HR) repair pathway in HeLa cervical cancer cells, and furthermore, reduced B55a expression and impaired DNA damage repair in lung carcinomas was found to sensitise these cells to the PARP inhibitor (PARPi) ABT888, through synthetic lethality. </span></p><p style="margin-bottom:0cm;margin-bottom:.0001pt;line-height:150%;"><span style="font-size:12.0pt;line-height:150%;font-family:'Times New Roman',serif;"></span></p><p style="margin-bottom:0cm;margin-bottom:.0001pt;line-height:150%;"><span style="font-size:12.0pt;line-height:150%;font-family:'Times New Roman',serif;">This study therefore investigated the role reduced B55a expression may play in breast cancer cells, to determine whether this is a potential treatment target for low-B55a expressing luminal-B tumours. It was first hypothesised, based on past studies, that reduced B55a expression in breast cancer cells would impair their DNA damage repair pathways. To investigate this, two B55a knockdown models were created in both<span>&nbsp; </span>MCF7 and ZR751breast cancer cell lines, as well as a control cell line to compare back to. DNA repair efficiency was then examined by inducing DNA damage via Bleomycin and analysing expression of important HR repair proteins. Changes in expression and phosphorylation mediated activation of many of these proteins, as well as prolonged increase of ɣH2AX (marker for DSBs) in B55a-low cells compared to control cells supported the hypothesis that DN repair was impaired in these B55a-low cells. </span></p><p style="margin-bottom:0cm;margin-bottom:.0001pt;line-height:150%;"><span style="font-size:12.0pt;line-height:150%;font-family:'Times New Roman',serif;"></span></p><p style="margin-bottom:0cm;margin-bottom:.0001pt;line-height:150%;"><span style="font-size:12.0pt;line-height:150%;font-family:'Times New Roman',serif;">It was then hypothesised that impaired DNA repair in B55a-low breast cancer cells would further sensitise these cells to DNA damaging agents. To examine this, B55a knockdown and control cells were treated with DNA damaging agents (ɣ-irradiation, Bleomycin, Cisplatin, ABT888), at various doses. However the hypothesis was not supported, as there was no significantly increased sensitivity to these agents in B55a-low cells compared to the control cells.</span></p><p style="margin-bottom:0cm;margin-bottom:.0001pt;line-height:150%;"><span style="font-size:12.0pt;line-height:150%;font-family:'Times New Roman',serif;"></span></p><span style="font-size:12.0pt;line-height:107%;font-family:'Times New Roman',serif;">Therefore while this study suggests that DNA repair may be altered and impaired in B55a-low breast cancer cells (and hence luminal-B tumours), this finding is currently not translatable to use as a potential treatment target for patient with luminal-B tumours. However future studies using altered dosage and time course of DNA damaging agents may find a heightened sensitivity of B55a-low breast cancer cell lines, allowing for specific personalised treatment of patients with aggressive luminal-B tumours, using therapeutics that already currently available. </span> |

Investigation of the function of tetraspanins CD9 and CD151 on prostate exosomes Exosomes are nanosized, membranous vesicles secreted by most cells that have been shown to be important for cellular communication. Whilst most research into exosomes has focussed on their function in a diseased state, such as cancer, their role in normal cellular functioning has not been thoroughly investigated. Tetraspanins are a family of transmembrane proteins, including CD9 and CD151, that are abundantly expressed on exosomes, however, their function within exosomes is yet to be fully elucidated. CD9 and CD151 have opposing roles in many solid tumours, including prostate, where CD9 is typically downregulated and CD151 is typically upregulated and both being indicative of poor prognosis. Therefore, this study was designed to investigate the effects that altered CD9 and CD151 in exosomes have on a normal cellular population, and whether alteration of these tetraspanins can make a normal cell more metastatic.<br />CD9 and CD151 expression was altered in a normal, non-tumourigenic cell line (RWPE1) to express either low CD9 (CD9 low) or high CD151 (CD151 high). Western blot and flow cytometry were used to confirm that these cell lines displayed altered expression of CD9 and CD151 and that their control lines (Scram and Zeo respectively) displayed similar expression to RWPE1 cells. An invasive and metastatic derivative cell line of RWPE1 cells, WPE1-NB26, was used as a tumourigenic control. Exosomes from these cells were then assessed for their ability to attach to and internalise into RWPE1 cells before being used as treatments for RWPE1 cells in a range of functional assays, including adhesion, proliferation, migration and invasion, to assess whether the altered exosomal expression of CD9 and CD151 can influence these cellular behaviours. Exosomes from RWPE1, CD9 low, CD151 high and WPE1-NB26 cell lines were also analysed using a quantitative mass spectroscopy approach to determine changes in their proteome.<br />There were no differences observed between exosome populations in regards to attachment and internalisation into RWPE1 cells. Treating RWPE1 cells with exosomes also showed no difference in the proliferation of RWPE1 cells over a 72<br />6<br />hour period. RWPE1 cell adhesion to Collagen-IV, Fibronectin and Laminin 1 was assessed and revealed no difference for CD9 low exosome treated cells, however, an increase in adhesion was seen with the CD151 high exosome treated cells at 1 (p = 0.0023) and 4 hours (p = 0.0279). Only CD151 high exosome treated RWPE1 cells showed an increase in migration at 20 (p = 0.0186), 24 (p = 0.0068) and 30 hours (p = 0.0038), however no differences were observed in an invasion assay. Proteomic analysis of exosomes revealed that there were 101 proteins with a greater than 2 fold increase and 18 proteins with a greater than 2 fold decrease in abundance compared to RWPE1 exosomes.<br />The results of this study suggest that alterations of CD9 and CD151 in exosomes have only limited functional effects on a normal cellular population. This study also identified that altering the expression of CD9 and CD151 in exosomes affects their entire proteome. Further characterisation of the effects of CD9 and CD151 expression in exosomes needs to be performed, utilising a panel of tumourigenic cell lines. Therefore due to the alterations on cellular function upon the addition of CD151 high exosomes, it suggests that modified exosomes could represent a therapeutic strategy for prostate cancer. |
