BAX and prostate carcinoma: Recently, the Pg inhibition of cell growth, followed by apoptosis of highly aggressive human prostate carcinoma PC3 cells through modulations in the cyclin kinase inhibitor-cyclin-dependent kinase machinery have been shown by Malik et al. These events were associated to alterations in the levels of Bax and Bcl-2, shifting the Bax: Bcl-2 ratio in favor of apoptosis (47).
