Fig. 1: Exclusive inhibition of GBM cell lines induced via the pan-Bcl-2 inhibitor obatoclax.

Cell viability was measured using the CellTiter-Glo assay after 72 h of treatment and presented as mean ± SD. A Heatmap of inhibitor library screening on 8 GBM cell lines with 92 compounds with known targets. The cell viability in non-treated (DMSO) controls was calculated as 100%. Treatment time was 72 h with concentrations indicated in Supplementary Table 1. B Comparison of sensitivity to 1 µM of obatoclax and navitoclax in 8 GBM cell lines after 72 h (n = 6). C Comparison of dose–response curves of 72 h treatment for obatoclax, navitoclax, and venetoclax in the Onda7, DK-MG, and YH-13 cell lines (n = 3).
