Fig. 1From: Tunicamycin specifically aggravates ER stress and overcomes chemoresistance in multidrug-resistant gastric cancer cells by inhibiting N-glycosylationTunicamycin exerts strong cytotoxic effects on MDR GC cells, which correlates with basal ER stress. a Cell survival after Tu treatment for 48 h assayed by CCK-8. Tu, tunicamycin. The values in the untreated group are identified as the baseline, namely 100% survival. b Expressions of ER stress-associated proteins in cells without treatment. β-actin served as the loading control. All proteins were normalized to β-actin.
