Abstract:
:We established an etoposide (VP-16)-resistant human small-cell lung cancer cell line (H69/VP) by stepwise exposure to VP-16. The resistance of H69/VP to VP-16 was 9.4-fold that of the parent cell line (H69/P). H69/VP showed cross-resistance to Adriamycin (ADM), (4S)-4,11-diethyl-4-hydroxy-9-[(4-piperidinopiperidino) carbonyloxy]-1H-pyrano[3',4':6,7]indolizino [1,2-b]quinoline-3,14(4H,12H)-dionehydrochloride trihydrate (CPT-11), teniposide (VM-26), vindesine (VDS) and vincristine (VCR). The amount of DNA topoisomerase II (topo.II) was nearly the same in H69/P and H69/VP cells. The catalytic activity of topo.II in H69/VP cells was lower than that in the H69/P line. Accumulation of [3H]-VP-16 in H69/VP was 6.1-7.5 times lower than that in H69/P. According to Northern blot analysis, the mdr-1 mRNA level in H69/VP was markedly higher than that in H69/P. These findings suggest that H69/VP has a typical multidrug resistance (MDR) phenotype and that alteration of the drug accumulation mediated by P-glycoprotein may play an important role in resistance to VP-16. Reduced topo.II activity may also be associated with VP-16 resistance.
