Genome-wide analysis of RNA-binding protein PSF-associated transcripts in prostate cancer

Prostate cancer is the most common cancer in men and androgen receptor (AR) downstream signalings promote prostate cancer cell proliferation. PSF is an RNA-binding protein which is involved in AR signaling. To investigate the role of PSF, we performed RNA immunoprecipitation (RIP) and crosslinking immunoprecipitation (CLIP) sequence analysis in AR-positive prostate cancer cell line, LNCaP. In addition, we used hormone-refractory prostate cancer model cells 22Rv1 and long term androgen deprivation (LTAD) cells to explore the differences of PSF function in prostate cancer progression. Overall design: RIP and CLIP sequence analysis of PSF in three prostate cancer cell lines.
