Objective: To investigate the reversal or effect of multi-drug resistance by nitidine chloride(NC) on A2780 Taxol cell. Method: The reversal efficacy of NC was determined by MTT assay. The expressionof multidrug resistance 1 (MDR1) mRNA was assessed by reverse transcription-polymerase chain reaction (RT-PCR).The structural changes of A2780 Taxol cell were examined with hematoxylin and eosin staining(HE).The apoptosis of A2780 Taxol cell was detected by TUNEL assay. Result: The resistance fold of A2780 Taxol cell was 1.87
1.07
3.25 for adriamycin(ADM)
etopaside(VP-16)
hydroxycamptothecin(HCPT).The 50% inhibition concentration(IC50) value of A2780 Taxol cell was reduced by NC(0.375
0.75
1.5 mg·L-1) combined with ADM
VP-16 or HCPT
and NC could decrease the expression of MDR1-mRNA
change the structural of A2780 Taxol cell. The apoptosis index (AI) was(58.03±1.46)% detected by TUNEL assay. Conclusion: Nitidine chloride can reverse the multidrug resistance of A2780 Taxol cell.
