ER stress induced the spliced pXbp1 mRNA and active pXbp1 protein. Tunicamycin treatment induced spliced pXbp1 mRNA (A) and active pXbp1 protein (B) from 3 h. β-actin was used as the loading control. (C) Quantification of the Western blot analysis in (B). Data were presented as means ± SD from three independent experiments.
