Abstract: Abstract: Objective To study the effect of staurosporine (ST) on cell proliferation and apoptosis in oral squamous cell carcinoma cell line CAL27 and to explore the possible mechanisms. Methods After CAL27 cells were treated with different concentrations of ST for different durations, cell proliferation was assessed by CCK-8 method, cell apoptosis was detected by AnnexinV-FITC Apoptosis Detection Kit and flow cytometry, cell cycle distribution was investigated by flow cytometry, and expression of cyclin B1 and Cdk1 proteins was detected by Western blot. Results ST significantly inhibited the proliferation of CAL27 cells (P < 0.05) in a dose- dependent manner and the apoptosis rate of CAL27 cells treated with ST increased significantly compared with the controlled cells (P < 0.05). Treatment with ST induced cell cycle arrest in G2/M phase (P < 0.05). Moreover, ST treatment significantly decreased the expression of cyclin D1 、Cdk4 and Cdk6 proteins and increased the expression of P21 in CAL27 cells (P < 0.05).Conclusion ST significantly inhibits proliferation and induces apoptosis of CAL27 cells possibly by inducing cell cycle arrest in G2/M phase.
