Attenuation of androgenic regulation by brefeldin A in androgen-responsive prostate cancer cells

BFA is capable of attenuating androgenic regulation in LNCaP cells such as androgen-stimulated PSA synthesis/secretion and cell growth. This BFA-blocked androgen action appears to be primarily attributed to severe inactivation of AR with BFA because AR is a crucial factor for relaying androgenic messages (to DNA). Therefore, BFA could be considered a promising agent for a more effective treatment of hormone-dependent prostate cancer.
