Effects of PSF inhibitors on gene expression profile in prostate cancer cells [microarray]

Prostate cancer is the most common cancer in men and AR downstream signalings promote prostate cancer cell proliferation. Although initially hormone-deprovation therapy is effective to inhibit cancer progression, most of cancers relapse as castration-resistant prostate cancer (CRPC). PSF is one of RNA binding proteins associated with prostate cancer progression. In this study, we examined the effect of small molecule treatment interacting with PSF in CRPC cells. In order to investigate the effect of small molecule interacting with PSF cells, we analyzed gene expression profile in AR-positive prostate cancer cell line LNCaP and CRPC model cell derived from LNCaP cells.We treated LNCaP cells with vehicle or dihydrotestosterone (DHT) for 24 h. LTAD cells were treated with siControl or siPSF (10 nM) for 48 h. LTAD cells were treated with vehicle or small molecule interacting with PSF (No.10-3) for 48 h. Global analysis of gene expression changes in prostate cancer cells after treatmet with siRNA targeting PSF or small molecule interacting with PSF using microarray.
