Fig. 1From: High-throughput sequencing of circRNAs reveals novel insights into mechanisms of nigericin in pancreatic cancerSensitivity of human PC cells to nigericin. a, b PANC-1 and SW1990 cells were exposed to increasing concentrations of nigericin for different time periods (0, 8, 16 or 32 h), and nigericin treatment significantly reduced the cell viability in a concentration-dependent manner. c, d The IC50 values of nigericin in PANC-1 and SW1990 cells at different time points (8, 16 and 32 h) were calculated and compared. Nigericin inhibited the cell viabilities time dependently. (*P < 0.05)Back to article page
