Project description:There is overwhelming evidence indicating that human cancer is a genetic disease caused by sequential accumulation of mutations in oncogenes and tumor suppressor genes. However, it is also increasingly apparent that cancer depends not only on mutations in these coding genes, but also on alterations in the large class of the non-coding RNAs (ncRNAs). Here, we report that one such long ncRNA, TRPM2-AS, an antisense transcript in respect to TRPM2, a gene encoding for a ion channel activated by oxidative stress, is significantly overexpressed in prostate cancer. High expression levels of either TRPM2-AS or of a related gene signature are linked to poor clinical outcome, with the related gene signature working also independently of the patient's Gleason score. Moreover, TRPM2-AS knock-out leads to apoptosis of prostate cancer cells, with transcriptional profiling indicating an unbearable increase of cellular stress in dying cells, coupled to the down-regulation of several already known oncological targets. Considering that TRPM2-AS transcripts are barely detectable in healthy cells, these data strongly suggest that it, beside being a novel prognostic marker, is also a suitable therapeutic target in prostate cancer and establish a strong rationale for developing agents targeting either its expression or the expression of molecules in its pathway. PC3 cells were transfeted either a non-specific siRNA or with a TRPM2-AS siRNA in replicates. Cells were grown for 48 hours, then were harvested and RNA was isolated
Project description:PC3 are a metastatic prostate cancer cell line. Microarray analysis was performed to evaluate the impact of miR-149-3p overexpression or DAB2IP depletion in PC3.

Project description:To investigate the regulatory effect of hsa_circ_0070512 gene on prostate cancer cell line PC3, we established the PC3 hsa_circ_0070512 overexpressing cell line (OE) and its negative control group (vector). Then we used RNA-seq to obtain gene expression profile analysis
Project description:Human prostate carcinoma cell line PC3 was treated with 10mg/ml or 100mg/ml of Abacavir. Gene expression was analyzed on total RNA extracted 48h after treatement. For each condition, 5 indipendent biological replicates were performed
