Research Abstract

We tried to identify androgen-regulated miRNAs and ncRNAs(Non-coding RNAs) in prostate cancer cell. First, We found several miRNAs are situated in the vicinity of AR binding sites we identified by ChIP-chip analysis. We also identified androgen responsive miRNAs and ncRNAs by large scale screening such as CAGE or short RNA sequence. Notably, we showed miR-148a is a primary androgen regulated miRNA strongly expressed in prostate cancer cells. Furthermore, we also found MiR-148a promotes prostate cancer cell proliferation.
