Brain cancer stem-like cell genesis from p53-deficient mouse astrocytes by oncogenic Ras.

abstract：:The newly identified drug transporter MRP is functionally linked to a multiple drug resistance independent from P-glycoprotein. Resistance modifiers for this type of MDR are rare at present. We analyzed the modulating effect of the highly selective bisindolylmaleimide PKC inhibitor GF 109203X on the MRP overexpressing...
