CDK1 and carcinoma: α-Pinene, at 1000 μg/mL, inhibited the human carcinoma hepatocellular BEL-7402 cells proliferation, arresting cell growth in the G2/M phase of the cell cycle, decreasing gene and protein expressions of Cdc25C, and reducing the cycle dependence on kinase 1 (CDK1) activity [32,33].
