Clonogenic survival of HepG3 cells continuously exposed to 4PYR. HepG3 cells were exposed to 25, 50, and 100 µM of 4PYR for six days then stained with crystal violet (A). Cell density was assessed by measuring the area fraction of the crystal violet-stained cells after 4PYR exposure (B). Results are presented as percentage cell density to control ± SEM of three independent experiments. Statistical significance: *** p < 0.001, **** p < 0.0001.
