Fig. 5From: COX-2 strengthens the effects of acid and bile salts on human esophageal cells and Barrett esophageal cellsEffects of acid on the proliferation of HET-1A and BAR-T cells. A After 30-min treatment of HET-1A cells and 60-min treatment of BAR-T cells, cell proliferation was assessed by MTS in different concentrations of hydrochloric acids. B, C After 30-min treatment of HET-1A cells and 60-min treatment of BAR-T cells, the expression levels of COX-2 were determined by western blot in different concentrations of hydrochloric acids. The data are shown as the mean ± SD. *p < 0.05, **p < 0.01, ***p < 0.001, N.S, no significant effectBack to article page
