Therapeutic potential of targeting AKR1C2 in the treatment of prostate cancer.

Prostate cancer development and progression are driven by androgens, and changes in androgen metabolic pathways can lead to prostate cancer progression or remission. AKR1C2 is a member of the aldo-keto reductase superfamily and plays an important role in the metabolism of steroids and prostaglandins. Alterations in the expression and activity of AKR1C2 affect the homeostasis of active androgens, which in turn affects the progression of prostate cancer. AKR1C2 reduces the highly active dihydrotestosterone to the less active 3α-diol in the prostate, resulting in lower androgen levels. Whereas the expression of AKR1C2 is significantly reduced in prostate cancer tissues relative to normal prostate tissues, this results in a weakening of the dihydrotestosterone metabolic inactivation pathway, leading to the retention of dihydrotestosterone in the prostate cancer cells, which promotes the progress of prostate cancer. Given the critical role of AKR1C2 in prostate cancer cells, targeting AKR1C2 for the treatment of prostate cancer may be an effective strategy. It has been demonstrated that curcumin and neem leaf extract effectively inhibit prostate cancer in vitro and in vivo by modulating AKR1C2. [ABSTRACT FROM AUTHOR]
