Název v původním jazyce

Transport and cytotoxicity of paclitaxel, docetaxel, and novel taxanes in human breast cancer cells

Popis výsledku v původním jazyce

This study compared cytotoxicity and transport of paclitaxel and docetaxel with novel taxanes in human breast cancer cells. The cell lines examined differ expression of ABC membrane transporters. Reverse transcription-polymerase chain reaction revealed that NCI/ADR-RES cells expressed high levels of P-glycoprotein mRNA, which was absent in MDA-MB-435 cells, while the opposite was true for MRP2 mRNA. NCI/ADR-RES cells were more resistant to paclitaxel and to docetaxel than MDA-MB-435 cells, but almost equally sensitive to novel taxanes. This complied with the fact that NCI/ADR-RES cells absorbed almost 20-fold less [14C]paclitaxel, about 7-fold less docetaxel, and almost equal amounts of SB-T-1103, SB-T-1214, and SB-T-1216 as the MDA-MB-435 cells. SB-T-1103 and SB-T-1216 did not influence transport of paclitaxel, but SB-T-1214 decreased [14C]paclitaxel uptake in both cell lines indicating inhibition of uptake. This suggests that the novel taxanes are not inhibitors of P-glycoprotein.
