Abstract:

PURPOSE: To investigate the molecular mechanism of cell cycle arrest induced by tyrosine protein kinase inhibitor, genistein, in human salivary adenoid cystic carcinoma cell line SACC-83.

METHODS: SACC-83 cells cultured in vitro were treated with genistein, the expressions of CyclinB1, Cdk1, CyclinD1 and Cdk4 proteins were detected with Western blotting, and the results were quantitatively analyzed by FluorChem V2.0 software, statistical analysis was performed with analysis of variance using SPSS11.5 software.

RESULTS: With the increase of concentration of genistein and the elongation of time, the expression of CyclinB1, Cdk1, CyclinD1 and Cdk4 proteins was significantly decreased. Treated with 220 micromol/L of genistein for 3 days, the expression level of CyclinB1, Cdk1, CyclinD1 and Cdk4 proteins was 58%, 64%, 46% and 43% of the control group, respectively (P<0.01).

CONCLUSION: The cell cycle G2/M arrest induced by genistein in human salivary adenoid cystic carcinoma cell line SACC-83 may be associated with the downregulations of CyclinB1, Cdk1, CyclinD1 and Cdk4 protein expressions.
