Outline of Final Research Achievements

In this study, we investigated the role of antisense RNA, expressed in the antisense direction of protein coding gene, among long non-coding RNAs regulated by androgen receptor (AR) in prostate cancer. First, we identified a novel androgen-inducible non-coding RNA situated in the antisense region of CTBP1 gene, and then we named it as CTBP1-AS. We found the androgen-dependent accumulation of this antisense RNA in the nucleus of prostate cancer cells and the epigenetic mechanism for prostate cancer progression by CTBP1-AS. We also identified additional antisense RNAs regulated by androgen using directional RNA-seq analysis in prostate cancer cells.
