摘要: We examined the expression levels of mRNA for multidrug resistance 1 (MDR1), resistance-associated protein (MRP), human canalicular multispecific organic anion transporter (cMOAT), lung resistance-related (LRP), topoisomerase IIalpha, beta (Topo beta) and I I) genes in head neck squamous cell carcinoma (HNSCC) specimens mucosa (HNM) specimens, to elucidate their roles relation biological characteristics drug vivo. Fifty-eight samples (45 carcinomas 13 mucosa) obtained during surgical resection or biopsy from 38 patients were analyzed using quantitative reverse transcription-polymerase chain reaction (RT-PCR) method. MDR1, MRP, LRP, Topo IIbeta, gene transcripts detected all tested, but cMOAT was not them. Comparisons HNSCC with those HNM showed that IIalpha level higher than (P=0.0298). Moreover, significantly metastatic lymph node (P=0.0205). There no significant differences six genes' between exposed platinum drugs drugs. These results suggest it may be effective anticancer therapy use topoisomerase-targetting against HNSCC, especially tumors, these is associated exposure.
