Title: Roscovitine on cell cycle in mitotic hepatoma carcinoma cell
Abstract: Objective To study the influences by a Cyelin-dependent kinase inhibitor Roscovitine on cell cycle in mitotic hepatoma carcinoma cell SMMC-7721. Methods Microscope,MTT, flow cytometry and R-T PCR were used to observe the effects of Roscovitine on morphology, proliferation, cell cycle, apoptosis and the mRNA expression of CDK2, Caspase-3, bcl-2 in SMMC-7721 cells. Results Roscovitine inhibited the proliferation of SMMC-7721 cells in dosage and time dependent manner and induced apoptosis. Flow cytometry showed the ratio of G0, G1 increased. R-T PCR showed that the expression of bcl-2 reduced, Caspase-3 increased. Conclusion Reseovitine can inhibit the growth, proliferation, block the cell cycle at G0/G1 and promotes apoptosis of mitotic SMMC-7721 cells, and the mechanism of apoptosis is dependent on the activity of bcl-2 and Caspase-3.
