Figure 2From: ABT-888 enhances cytotoxic effects of temozolomide independent of MGMT status in serum free cultured glioma cells PARPi and TMZ monotherapy efficacy in GS cultures. A) Panel of GS cultures tested for sensitivity to PARPi at 10 uM. Readout of viability was performed at day 5 and is depicted as a percentage when compared to non-treated controls. * Illustrates a p-value <0.05. B) GS culture panel tested against indicated concentrations in uM of TMZ monotherapy. Viability at day 5 is indicated as percentages when compared to paired non-treated controls. * indicates p < 0.05 as compared to non treated controls. C) Overview of western blotting results derived from GS cultures. MGMT protein expression is indicated with actin protein expression used as a loading control. TMZ sensitivity is indicated with an S (sensitive), R (resistant) and ND (TMZ sensitivity not determined in monotherapy screen). For several GSCs protein isolates were loaded in separate runs as technical controls.Back to article page
