1Capsaicin exerts anti-benign prostatic hyperplasia effects via inhibiting androgen receptor signaling pathway显示文摘Background:Benign prostatic hyperplasia(BPH)is a common condition in middle-aged and elderly men.Enlargement of the prostate causes lower urinary tract symptoms.Capsaicin is a phytochemical extracted from chili peppers and exerts many pharmacological actions,such as anti-tumor and anti-inflammatory effects.Methods:Our study investigated the effect of capsaicin in vitro and in a mouse model in vivo.A prostatic stromal myofibroblast cell line(WPMY-1)was co-incubated with testosterone(1µM)and different concentrations of capsaicin(10–100µM)for 24 and 48 h.Capsaicin(10–100µM)significantly inhibited testosterone-treated WPMY-1 cell growth at 48 h by MTT assay.The testosterone propionate(7.5 mg/kg)-induced BPH mouse model was used to examine the anti-proliferative effect of capsaicin.Treatment with capsaicin(10 mg/kg)for 14 days significantly attenuated prostatic hyperplasia.Finasteride was used as a positive control.Results:Capsaicin significantly decreased prostate weight and prostate index(prostate/body weight ratio)in BPH mice.The expression of 5α-reductase type II,androgen receptor(AR)and prostate specific antigen(PSA)protein expression and PSA serum were all significantly reduced in capsaicin-treated BPH mice.In addition,capsaicin also activated transient receptor potential vanilloid 1 mediated apoptosis and autophagy in BPH mice.Conclusion:These results demonstrate multiple positive effects of capsaicin in controlling prostate growth and suggest its therapeutic potential in the treatment of BPH.ZICHEN SHAO CHUNG-YI CHEN XUZHOU CHEN HANWU CHEN MENGQIAO SU HUI SUN YIDAN LI BINGHUA TU ZITONG WANG CHI-MING LIU 2023BIOCELL2023,47,6:0
