Role of zinc homeostasis in the prevention of prostate diseases.

The prostate gland is the largest accessory sex gland in the male reproductive system, and is recognized for its elevated zinc concentration. Recently, the incidence of prostate diseases has increased, posing a significant threat to the health of men. Increasing evidence suggests that maintaining normal prostate function requires proper zinc homeostasis. Prostate disease can cause changes in the regulation of zinc levels in the prostate. Studies have indicated that patients with prostatitis, prostate enlargement, or prostate cancer experience an imbalance in zinc homeostasis, resulting in changes in zinc levels in the body and altered distribution of zinc in tissues. Zinc prevents the malignant transformation of normal prostate tissue by blocking citric acid oxidation, inducing apoptosis, and exhibiting antioxidant activity. Therefore, studying changes in zinc homeostasis in prostate diseases is of great clinical value for diagnosing and treating these diseases. This article reviews the distribution and content of zinc in the prostate, the mechanism underlying zinc homeostasis regulation, the role of zinc homeostasis in prostate diseases, and the clinical applications of zinc.
