Fig. 15. Effect of pre-treatment of WM266-4 cells with ER stress inhibitors on viability in the presence of 2155-14. (A) WM266-4 cell viability 24 h after 2155-14 addition. (B) WM266-4 cell viability 72 h after 2155-14 addition. 2155-14 was tested at 100 µM, STF-83010 (STF) was tested at 60 µM, N-acetyl cysteine (NAC) was tested at 10 μM, and GSK2606414 (GSK) was tested at 1 μM. The data shown were the mean ± SD, n=6. One-way analysis of variance (ANOVA) was used followed by Dunnett post hoc test. ***** - p<0.0001, *** - p<0.001, ** - p<0.01, * - p<0.05, ns - no significance.
