Transcriptional differences between the peripheral and the transcription zone of the prostate

ABSTRACT: The occurrence of cancer is not equally distributed across the three zones of the prostate gland; the peripheral (PZ), central and transition zones (TZ). The majority (~70%) of diagnosed prostate cancer (PCa) is found in the PZ compared to the TZ. In this study we comprehensively measure whole genome expression by next-generation sequencing of the PZ and TZ from prostate tissue. Our aim was to identify the molecular and metabolic differences between the two zones that could underlie the differential susceptibility to PCa incidence. Following histological assessment of tissue adjacent to the biopsies used for RNAsequencing we identified 4 out of the 18 samples to be cancerous. Although these are included in the ArrayExpress submission, they were not included in the final analysis of data that reported the molecular differences between morphologically normal peripheral and transition zones.

Tissue Proteome Signatures Associated with Five Grades of Prostate Cancer and Benign Prostatic Hyperplasia

Project description:Prostate cancer (PCa) remains a prevalent and deadly disease. The histology-based Gleason score (GS) of PCa tissue biopsy is the most accurate predictor of disease aggressiveness and an important measure to guide decision-making with respect to treatment strategies and patient management. However, inherent variability associated with PCa tumour sampling and the subjective determination of the GS are still key challenges precluding accurate diagnostication and prognostication. Thus, novel molecular signatures are urgently needed to distinguish between indolent and aggressive forms of PCa for better patient management and outcomes. Herein, we have used label-free LC-MS/MS-based proteomics to profile the proteome of 50 PCa tissues spanning five GS-based PCa grades (n = 10 per group) relative to five tissues from individuals with benign prostatic hyperplasia (BPH). Over 2,000 proteins were consistently identified albeit at different levels between and within the patient groups, revealing biological processes associated with specific grades. Excitingly, a panel of 11 prostate-derived proteins including IGKV3D-20, RNASET2, TACC2, ANXA7, LMOD1, PRCP, GYG1, NDUFV1, H1FX, APOBEC3C, CTSZ displayed the potential to accurately stratify patients displaying low and high GS. This is the first study to characterise the prostate tissue proteome signatures of the five PCa grades relative to BPH. We report a panel of proteins that accurately can distinguish low and high GS PCa tissues. These promising proteins can be further explored as candidate biomarkers for PCa aggressiveness.

Single-cell sequencing technology demonstrates cellular and functional heterogeneity within the prostate and between the transitional and peripheral zones

Project description:The identification of cellular and functional heterogeneity within the prostate and between the transitional zone (TZ) and peripheral zone (PZ) is critical for understanding the spatial distribution of prostate diseases. Three paired human prostate PZ and TZ tissue samples were used for scRNA-seq.

Co-expression of genes with ERG in prostate cancers

Project description:ERG overexpression is the most frequent molecular alteration in prostate cancer. We analyzed different stages of prostate cancer to identify genes that were coexpressed with ERG overexpression. In primary prostate tumors, it was shown that TDRD1 expression was the strongest correlated gene with ERG overexpression and we suggest TDRD1 as a direct ERG target gene. 48 Prostate cancer samples from radical prostatectomies were included in this study. These samples contained more than 70% cancer and less than 30% stromal tissue. Each sample was analyzed once.

MicroRNA expression data from human prostate cancer

Project description:MicroRNAs are small RNA molecules of about 21-25 nucleotides that regulate gene expression via posttranscriptional inhibition of protein synthesis. They play a vital role in the process of tumorigenesis. To identify and characterize the diagnostic potential of miRNAs in prostate cancer, a leading cause of tumor mortality, we performed microarray based screening of miRNA expression profiles. We selected 20 cases of moderately differentiated prostate cancer and generated pairs of tumor and corresponding normal tissue by microdissection

Human Prostate Cancer Illumina Infinium Human Methylation450 (HM450K bead array) BeadChip samples (benign vs tumor)

Project description:In order to examine the impact our probe filtering efforts might have on the analysis of real-world primary data, we analyzed clinical prostate cancer specimens. This included profiling of four prostate tumour tissue samples and four benign prostate tissues using the Illumina Infinium Human Methylation450 (HM450K bead array) BeadChip. These samples were used to explore the effects on analysis with and without a probe filtering. Four tumour samples containing Gleason 6 cancer and four benign samples from other prostate glands containing Gleason 6 cancer were selected for study. Tissue samples were cryosectioned for histopathological assessment. Genomic DNA was extracted from the homogenized samples using the Allprep Micro Kit (Qiagen, CA, USA) following manufacturer’s instructions and bisulfite converted using the Zymo EZ DNA Methylation kit (Zymo Research Corporation, CA, USA). The resulting libraries were hybridized onto the Illumina HumanMethylation450 (HM450K bead array) BeadChip. Raw intensity data was generated using an iScan microarray reader (Illumina).
