Abstract excerpt
The main cause of the multidrug resistance (MDR) of glioma cells is the overexpression of MRP-1, often associated with high levels of glutathione (GSH). We investigated whether MRP-1-related GSH content can influence (99m)Tc-glucarate entry by comparing its uptake with that of (99m)Tc-sestamibi (MIBI), an MRP- 1 probe, in an in vitro model of a sensitive cell line (U-87-MG) and a resistant derived cell line...
