Novel urinary and serological markers of prostate cancer using proteomics techniques: an important tool for early cancer diagnosis and treatment monitoring

Adeola, Henry Ademola January 2016 (has links)
In Africa, Prostate cancer (PCa) is the most frequently diagnosed solid organ tumour in males and use of prostate specific antigen (PSA) is presently fraught with diagnostic inaccuracies. Not least, in a multi-ethnic society like South Africa, proteome differences between African, Caucasian and Mixed-Ancestry PCa patients are largely unknown. Hence, discovery and validation of affordable, non-invasive and reliable diagnostic biomarkers of PCa would expand the frontiers of PCa management. We have employed two high-throughput proteomics technologies to identify novel urine- and blood-based biomarkers for early diagnosis and treatment monitoring of prostate cancer in a South African cohort as well as elucidate proteome differences in patients from our heterogeneous cohort. We compared the urinary proteomes of PCa, Benign Prostatic Hyperplasia (BPH), disease controls comprising patients with other uropathies (DC) and normal healthy controls (NC) both by pooling and individual discovery shotgun proteomic assessment on a nano-Liquid chromatography (nLC) coupled Hybrid Quadrupole-Orbitrap Mass Spectrometer platform. In-silico verification of identified biomarkers was performed using the Human Protein Atlas (HPA) as well as SRMAtlas; and verified potential biomarkers were experimentally prevalidated using a targeted parallel reaction monitoring (PRM) proteomics approach. Further, we employed the CT100+ antigen microarray platform to assess the differential humoral antibody response of PCa, DC and BPH patients in our cohort to a panel of 123 tumour-associated cancer antigens. Candidate antigen biomarkers were analyzed for ethnic group variation in our cohort and potential cancer diagnostic and immunotherapeutic inferences were drawn. Using these approaches, we identified 5595 and 9991 non-redundant peptides from the pooled and individual experiments respectively. While nine proteins demonstrated ethnic trend, 37 and 73 proteins were differentially expressed by pooled and individual analysis respectively. All 32 verified biomarkers were prevalidated with parallel reaction monitoring. Good PRM signals for 12 top ranking biomarker was observed, including PSA and prostatic acid phosphatase. We also identified 41 potential diagnostic and immunotherapeutic antigen biomarkers. Proteogenomic functional pathway analyses of differentially expressed antigens showed similar enrichments of biologic processes. We identified herein novel urinary and blood-based potential diagnostic biomarkers and immunotherapeutic targets of PCa in a South African PCa Cohort using multiple proteomics approaches.

EXAMINATION OF PROSTATE CANCER ASSOCIATED FACTORS FOR THEIR CONTRIBUTION TOWARDS THE DEVELOPMENT OF PROSTATE CANCER AND PROGRESSION INTO CASTRATION RESISTANT PROSTATE CANCER / PROSTATE CANCER ASSOCIATED FACTORS

Gu, Yan January 2021 (has links)
Although early detection and treatment of prostate cancer (PC) shows clinical benefit, advanced PCs that progress despite androgen deprivation therapy almost invariably result in castration resistance. This progression is lethal as castration-resistant prostate cancer (CRPC) are intimately associated with metastasis and remains the predominant cause of PC-related fatalities. Increasing evidence reveal a critical role of prostate cancer stem cells (PCSCs) in facilitatin g PC progression and acquisition of androgen independence. Taking advantage of our putative DU145 cell derived-PCSC population, we examined a number of candidate proteins for their contribution to PC progression and CRPC development. We identified three PCSC-specific proteins, BChE, CNTN1 and PCSK9. Butyrylcholinesterase (BChE) is a plasma enzyme known for its role in hydrolyzing ghrelin and bioactive esters, and is associated with altered metabolisms. Serum BChE is reduced in several cancer types. In this thesis we revealed a biphasic alteration of BChE and identified its downregulation at early stage of PC and upregulation at advanced stage PC. In a similar manner, we reported a functional role of CNTN1 in PC advancement. We demonstrate evidence for CNTN1-mediated enhancement of LNCaP cell proliferation in vitro and formation of CRPC in vivo, as well as its oncogenic potency in a prostate-specific CNTN1 transgenic model. Furthermore, we constructed a novel CNTN1-associated gene panel that predicts PC relapse risk with high robustness. IQGAP1 is critical in cytoskeletal dynamics which underlies cancer progression, metastasis, and PCSC biology. We showed IQGAP1 downregulation in both CRPCs and advanced PCs, and constructed a 27-gene signature using differentially expressed genes (DEGs) relative to this downregulation. This IQGAP1-relevant 27-gene panel robustly predicts PC relapse following radical prostatectomy and shows high translational value as a complementary panel to currently available commercial multigene panels. PCSK9 is an important protein in the regulation of cholesterol metabolism but its role in cancer is not known. We provide a comprehensive set of evidence supporting its role in the formation of CRPC, likely via mechanisms involving enhanced intratumoral uptake and sustained AR signalling under androgen-deprived conditions. Importantly, bigenic TRAMP mice deficient in PCSK9 have shown significantly prolonged survival and reduced metastasis. Collectively, we identified four factors with pivotal roles in PC development and progression into CRPC, albeit with different mechanisms. The altered expression of these factors in advanced PC and their widespread impact on a diverse range of mechanisms important in cell proliferation and survival underscores the importance of PCSCs in promoting advanced prostate cancer. Taken together, the findings of this thesis will advance our knowledge on PCSC-relevant pathways and their association with prostate cancer progression and metastasis. / Thesis / Doctor of Philosophy (Medical Science)

Cell-free DNA and tumor exosome cargo as diagnostic and prognostic marker for prostate cancer

Temilola, Dada 12 September 2023 (has links) (PDF)
According to the Global Cancer Statistics 2020, prostate cancer (PCa) is the second most commonly diagnosed male cancer and second leading cause of cancer death among men globally. Prostate cancer is known to be more aggressive among men of African origin with reasons not fully known. Previous studies have revealed PCa to be of a serious disease burden among African populations with PCa being the major cause of male cancer mortality. Prostate specific antigen (PSA) has long been introduced as a biomarker for screening in PCa diagnosis. However, serum PSA has low sensitivity for PCa diagnosis which has led to serious harm such as overdiagnosis and other complications of treatment for indolent disease. This makes it imperative to search for other novel biomarkers with high sensitivity and specificity for early diagnosis and management of prostate cancer. This study was aimed to characterize plasma and urinary cfDNA and tumour exosome cargo as diagnostic biomarker for PCa in South African populations with the goal of discovery of reliable, non-invasive, and novel biomarkers of PCa. We performed miRNA sequencing of exosomal RNA extracted from high and low Gleason's score PCa plasma samples. We performed differential expression (DE) of TCGA data and exosomal miRNA data and which we identified 185 miRNA and 65 miRNAs respectively. A comparison of the differential expressed TCGA miRNA and exosomal miRNA showed 13 miRNAs common between the two data with 7 of the 13 miRNAs expressed in the same direction. We further validated the expression of the 7 miRNAs using real time PCR in exosomal miRNA of high and low Gleason's score PCa samples and benign prostatic hyperplasia (BPH). We also performed whole exome sequencing of urinary cell free DNA and we identified 31 mutated genes. We reported for the first time an association between 27 of these genes and PCa in African populations. Four of the genes have earlier been identified as promising biomarker for prostate cancer diagnosis among African men. We also performed real time PCR quantification of cell free DNA to determine the concentration and DNA integrity of cfDNA in PCa and BPH of plasma and urine samples and which we were able to identify significantly higher plasma cfDNA level in PCa than BPH samples. We identified herein putative diagnostic biomarkers in plasma and urinary cfDNA and exosomes cargo for diagnosis of PCa in South African populations.
