The role of multi-drug resistance related proteins in hepatocellular carcinoma multidrug resistance cell line HePG2/ADM / 中国普通外科杂志

0. 05). At the protein level, the expressions of MDR1, BCRP and LRP in HePG2/ADM were significantly higher than HePG2 and L02 ( FMDR1= 28. 68, FBCRP= 18. 60, FLRP= 6. 28, P 0. 05). Conclusion The four genes are probably the normally expressed genes in the liver. The expression of MDR1 and BCRP could be up-regulated by anticancer agents in vitro. MDR1 and BCRP may play very important roles in the MDR of HePG2/ADM. However, MRP1 and LRP may have no relations with the multi-drug resistance of HePG2/ ADM cell lines.
