Abstract:
Objective To study multiple-drug resistance expression of CNE1 and CNE2 cell lines induced by radiation and its reversal by cyclosporine A and interferon. Methods Drug-resistant CNE1 and CNE2 cell lines were induced by radiation, and expression of P-gp, MRP, TOPⅡ and GST-? on protein and mRNA level were analyzed by flow cytometry and reverse transcription-polymerase chain reaction methods before and after radiation. At the same time, effect of cyclosporine A and interferon on multiple-drug resistance expression induced by radiation was studied. Results The results showed that expression of P-gp, MRP and GST-? proteins on CNE1 and CNE2 cell lines were up-regulated by radiation, and cyclosporine A and interferon could reverse the up-regulation of P-gp and MRP proteins induced by radiation. Conclusion Radiation can induce multiple-drug resistance in CNE1 and CNE2 cell lines, and it can be reversed by cyclosporine A and interferon.
