ABSTRACT
OBJECTIVE:
To investigate the effects of siRNA on the drug resistance reversal of ovarian cancer cell.METHODS:
The siRNA was transfected into human ovarian cancer cell line OVCAR8/TR by liposome. ATP-bioluminence assay was applied to measure the drug sensitivity to four chemotherapeutic agents before and after transfection.RESULTS:
ATP-bioluminence assay showed that OVCAR8/TR cells were resistant to cDDP, ADM and Taxol. After siRNA transfection, OVCAR8/TR cells were sensitive to ADM and Taxol which are tansported by P-gp. The inhibition rate of ADM was improved from 37% to 58%, and that of Taxol was improved from 26% to 78%. However, the resistance of OVCAR8/TR cells to cDDP was not reversed.CONCLUSION:
siRNA can effectively improve the drug resistance to chemotherapeutic agents which are transfered by P-gp. The RNA interference can reverse MDR1-mediated drug resistance in ovarian cancer cell.
