(Submitter supplied) MiRNAs are small non-coding RNAs that regulate the expression of specific mRNA targets mainly by translational repression, mRNA deadenylation or cleavage. This series is meant to identify miRNAs deregulated in prostate cancer (PCa) by comparing the PCa cell lines LNCaP, PC3 and Du-145 to the normal prostate epithelial cell line RWPE-1.

(Submitter supplied) Micro RNAs (miRNAs) miR-130a, miR-203 and miR-205 are jointly downregulated in prostate cancer and act as repressors of AR-signaling. MiRNAs are small non-coding RNAs that regulate the expression of specific mRNA targets mainly by translational repression, mRNA deadenylation or cleavage. Reconstitution of these lost miRNAs in the LNCaP PCa cell line cause morphology changes, growth arrest, and apoptosis, increasing when the miRNAs were co-expressed. more...

(Submitter supplied) The androgen receptor (AR) is a ligand-inducible transcription factor that mediates androgen action in target tissues. Upon ligand binding, the AR binds to thousands of genomic loci and activates a cell-type specific gene program. Prostate cancer growth and progression depend on androgen-induced AR signalling. Treatment of advanced prostate cancer through medical or surgical castration leads to initial response and durable remission, but resistance inevitably develops. more...

(Submitter supplied) MicroRNAs (miRNAs) function as regulators of cancer progression as they modulate different cellular processes. The objective of this study is to demonstrate a multi-dimensional function of miR-30e through regulating genes involved in various signaling pathways including androgen receptor signaling. miR-30e targets androgen receptor mRNA and functions as a tumor suppressor. We noted loss of miR-30e expression in prostate tumors and restored expression of miR-30e led to cell cycle arrest, induction of apoptosis, improved drug sensitivity in prostate cancer cells, and reduced tumor progression in prostate cancer xenograft models. more...

(Submitter supplied) In this study, the prognostic properties of miR-205 expression levels are investigated in a well-documented prostate cancer cohort. We show that miR-205 is correlated to shortened overall survival, significantly dividing the PCa patients into high and low risk groups. Furthermore, miR-205 is shown to inversely correlate to occurrence of metastases. In situ hybridization is also performed, demonstrating high miR-205 expression in the basal cells of benign prostate tissue glands. more...
