Abstract：
:Thirty human renal cell carcinomas and 94 non-small cell lung carcinomas of previously untreated patients were analyzed for the presence of P-glycoprotein, glutathione S-transferase-pi and topoisomerase II by means of immunohistochemistry. In the renal cell carcinomas investigated, two resistance markers were seen in 53% and three resistance markers in 36% of the cases. In only three tumors was one resistance mechanism observed. In the 94 non-small cell lung carcinomas 34% had two and 20% three resistance mechanisms, whereas 24% of the tumors revealed only one resistance mechanism. For determining the resistance of the tumors against drugs an in vitro short-term test was used. Only 12% of the sensitive lung tumors had more than one resistance mechanism, whereas 70% of the resistant tumors did. Thus a significant relationship exists between the resistance measured in vitro and the overexpression of P-glycoprotein or glutathione S-transferase-pi and the down-regulation of topoisomerase II.

杂志文章abstract：BACKGROUND:Cancer stem cells (CSCs) are tumour-initiating cells with self-renewal properties and chemo/radio-resistance. Regulatory T-cells (Tregs) influence CSCs through several mechanisms. In different solid tumours, the presence of both cell populations correlated with poor survival. In vulvar cancer, little is know...
