Endoplasmic reticulum (ER) stress, collagen, and α-smooth muscle actin (α-SMA) expression in hLFs. A: fold change of mRNA expression of binding immunoglobulin protein (BiP) in IPF and control hLFs upon TGF-β stimulation (n = 4 per group). Bars represent SE (P = 0.02). B: fold change of mRNA expression of X-box binding protein 1 (XBP1) in IPF and control hLFs upon TGF-β stimulation (n = 4 per group). Bars represent SE (P = 0.02). C: fold change of mRNA expression of collagen 1 in nonstimulated control and IPF hLFs and after a 6- and 24-h stimulation with TGF-β (5 ng/ml) (n = 5 per group). D: fold change of mRNA expression of α-SMA of nonstimulated and TGF-β stimulated hLFs (n = 4 control n = 3 IPF hLFs).
