Project description:Purpose: The goals of this study are to compare the serum extracellular vesicle (EV) delivered miRNA levels of patients with bone-metastatic prostate cancer (PCa), non-bone -metastatic PCa and benign prostatic hyperplasia (BPH), and to identify EV-delivered microRNAs in patient’s serum as indicators for bone-metastatic PCa. Methods:Serum extracellular vesicle delivered miRNA profiles of patients with bone-metastatic PCa or non-bone -metastatic PCa or BPH were generated by deep sequencing, using Illumina HiSeqTM 2500 platform Results: Using an optimized data analysis method, we mapped about 17 million sequence reads per sample. Differential analysis showed the expressions of 35 EV delivered miRNAs were significantly different between serum of patients with PCa and BPH, with a p value <0.05. the expressions of 5 EV delivered miRNAs were confirmed with qRT–PCR. Conclusions: Serum EV-delivered miR-181a-5p is a promising diagnostic biomarker for bone-metastatic PCa.

Methods:Serum extracellular vesicle delivered miRNA profiles of patients with bone-metastatic PCa or non-bone -metastatic PCa or BPH were generated by miRNA chip array, using Agilent-070156 Human_miRNA_V21.0_Microarray plateform. Results: Differential analysis showed the expressions of 27 EV delivered miRNAs were significantly different between serum of patients with bone-metastatic PCa and non-bone-metastatic PCa with a p value <0.05. the expressions of 5 EV delivered miRNAs were confirmed with qRT–PCR. Conclusions: Serum EV-delivered miR-181a-5p is a promising diagnostic biomarker for bone-metastatic PCa.

Project description:In this study, we aimed to identify a miRNA expression signature that could be used to distinguish PCa from BPH. We have shown for the first time in the literature the presence of miRNAs in the PSS. We suggest PSS as a powerful non-invasive source for evaluation of prognosis in PCa, since prostate massages can be easily applied during routine examination. Our results showed that certain differentially expressed miRNAs in PSS could be used as diagnostics markers. Prostate secretion samples (PSS) from 23 PCa and 25 benign prostate hyperplasia (BPH) patients were obtained from Urology Department of Bagcilar Educational and Research Hospital (Istanbul). MicroRNA (miRNA) profiling of eight PSS (four from BPH, four from PCa patients) were performed using microarray. Four of significantly deregulated miRNAs were further confirmed using quantitative reverse-transcription PCR (qRT-PCR). Statistical analysis was performed using Student’s t-test. ROC curves were plotted with SPSS-15.0.

Project description:It is well known that prostate cancer (PCa) is a progressive disease involving multiple gene alterations. The Gleason score (GS) is a morphologic feature of PCa used in the clinic to evaluate the risk of disease progression. However, GS often fail to clearly distinguish between indolent and aggressive disease. The aim of this study was to identify potential biomarkers for PCa risk stratification. An in-depth proteomics analysis (LC ESI-MS/MS) was performed on human PCa and BPH tissues. First, we identified differentially expressed proteins between PCa and BPH samples. We then filtered the proteins based on peptide spectrum matches and selected a panel of candidates. To assess and validate the clinical significance of these peptides we performed an integrative bioinformatics analysis using public database repositories. We identified YWHAZ, an androgen receptor downstream target, as one of the proteins enriched in PCa compared with BPH. We also found a strong association of YWHAZ expression with poor prognosis across different PCa datasets. Briefly, overall and relapse-free survival were significantly shorter in PCa cases expressing high vs. low YWHAZ expression. Further, multivariate analyses displayed high significant correlation with poor prognosis, independent from GS, age, PSA at diagnosis and TMPRSS2-ERG fusion. A multi-cancer screening for YWHAZ unveils amplification as the main alteration for this gene correlating with increased mRNA expression levels across all types of cancer through the cBioPortal platform. YWHAZ rises as a promising prognostic factor in PCa, independent from GS, aiding in disease risk stratification.

Project description:In order to detect proteins sensitive and specific enough to detect early stages of PCa, we performed a complex comparative proteomic study analyzing urine as a source for non-invasive biomarkers. We compared urine samples from patients with early PCa stages and Gleason score between 6 and 7 with samples from patients with BPH and other urological cancers, namely bladder and renal. The main goal of this study was to discover a diagnostic biomarker or set of biomarkers in urine, sufficiently sensitive to detect PCa in its early stages and specific enough to separate the disease from BPH or other urological cancers.
