Witamin D 's ability to do inhibit prostate cancer cell growth has been demonstranted in laboratoria models. In vitro studies show that calcitriol induces cell cycle arrest, promotes differention, and triggers apoptosis in prostate cancer lines such as LNCaP and PC- 3. Moreover, VDR polymorphisms have been linked to varying prostate cancer risk across populations, further supporting a geneticmigenenetic interplay.
