姜黄素抑制多药耐药肝癌细胞HepG2/ADM的增殖及其机制研究
Study on effect of curcumin in inhibiting proliferation of multidrug resistant liver cancer HepG2/ADM cells and its mechanism
摘要
Abstract
Objective To observe the inhibitory effect of curcumin on the proliferation of multidrug resistance liver cancer line HepG2/ADM cells and to explore its mechanisms.Methods HepG2/ADM cells were prepared and cultured in vitro,and treated by different concentrations (5,10,20,40 μmol/L) of curcumin for 24,48,72 h respectively.The effect of curcumin on proliferation of HepG2/ADM cells was measured by CCK-8 reagent;the concentration of intracellular rhodamine-123 (Rh-123) and adriamycin (ADM) were determined by flow cytometry;the level change of intracellular mdr-1 mRNA in each group was determined by RT-PCR,the P-gp protein level was detected by Western blot.Results Compared with the blank control and DMSO group,curucmin had more obvious inhibitory effect on HepG2/ADM cells proliferation (P<0.05),and could more remarkably inhibit the intracellular Rh-123 excretion(P<0.05).The RT-PCR and Western blot results showed that curcumm more significantly decrease the mdr-1 mRNA and P-gp protein levels in dose-time dependent manner (P<0.05).Conclusion Curcumin could significantly inhibit the proliferation of multidrug-resistant HepG2/ADM cells,and its mechanism may be related with inhibiting mdr-1 gene expression and its encoded P-gp protein level,which are closely related with MDR.关键词
