In PC3 prostate cancer cell, 4-HNE induced G2/M cell cycle arrest by decreasing p-Cdc2 (entry into M phase is determined by activation of the Cdc2 protein kinase, which requires Cdc2 dephosphorylation); increased amount of p-H2A.X indicated that 4-HNE induced apoptotic cell death after a G2/M accumulation [340]. Here, CDK1 is linked to prostate cancer.
