Abstract:
Object To study the inhibitory effects and mechanism of pseudolaric acid B (PAB) on the growth of LiBr cell line. Methods PAB in different concentrations was added into the medium in which LiBr cells were cultured. The changes of cell morphology were observed by phase contrast microscope. Cytotoxicity of PAB was detected by MTT. The number of apoptotic cell was calculated by double fluorescent staining. The level of p21 WAF1 protein was measured with immunocytochemistry. Results The growth of LiBr cell line was remarkably inhibited by PAB. The IC 50 values of PAB for LiBr cells was 2.5?10 -5 mol/L. The inhibitory rate and the apoptotic cell rate were related with the medicine concentration. The level of p21 WAF1 protein in LiBr cells treated with PAB was obviously increased. Conclusion PAB can effectively inhibit the proliferation of LiBr cell line.
