ABSTRACT
Aim This study was designed to investigate the inhibition of matrine on U251 glioma cell line and its mechanism. Methods MTT was used to measure the levels of the proliferation of U251 cultured with matrine in different concentrations.The effects of matrine on cell cycle of U251 were observed by FCM. The expression of proto oncogenes c myc was measured by RT PCR. Results The proliferation of U251 was obviously inhibited by matrine in a dose dependent manner. The inhibitory rate was (53 7?6 0)%,when cultured with matrine at 0 10 g?L -1 . The outcome of FCM showed that the proportion of G 0/G 1 phase cells were decreased. The proportion of S phase cells were reduced obviously,when cultured with matrine at 0 10 g?L -1 in 3 days.The outcome of RT PCR showed that the expression of proto onco gene C myc was notably decreased, when the dose of matrine was increased. Conclusion Matrine can inhibit the proliferation of U251 and inhibit the expression of proto onco gene C myc.
