Abstract：【Objective】To investigate the effect of propofol on the proliferation of prostate cancer cell line (LNCaP) stimulated by dihydrotestosterone (DHT) and its mechanism. 【Methods】 LNCaP cells were divided into four groups according to the intervention mode: control group (normal saline), DHT group (10 nM DHT intervention), DHT + 10 μm propofol group (10 nM DHT + 10 μM propofol intervention) and DHT + 50 μM propofol group (10 nM DHT + 50 μM propofol intervention). Real time quantitative PCR was used to detect the levels of androgen dependent gene prostate specific antigen (PSA), FK506 binding protein 5 (FKBP5) and transmembrane protease serine 2 (TMPRSS2). MTT method was used to analyze the survival of cells in each group. Western blot was used to detect the expression of AR and hypoxia inducible factor (HIF) in cells in each group. 【Results】 Compared with the DHT group, the expression of PSA, FKBP5 and TMPRSS2 genes in the DHT+10 μM propofol group and the DHT+ 50 μM propofol group decreased significantly at 24 hours (P<0.05). Propofol exposure for 12 h and 24 h could significantly inhibit the proliferation of LNCaP cells (P<0.05), but exposure for 4 h had no significant effect. Compared with the DHT group, the expression of AR and HIF-1α protein in nucleus of the DHT + 10 μM propofol group and the DHT+50 μM propofol group were significantly lower (P<0.05). 【Conclusion】 Propofol inhibits the proliferation of LNCaP cells and AR transcriptional activity, so as to reduce the level of AR nucleoprotein.
