Fig. 4From: IL-33/ST2L signaling alleviates diabetic nephropathy by regulating endoplasmic reticulum stress and apoptosisER stress-related factors in Control, STZ, STZ + IL-33, and STZ + sST2 mice. (A) Quantitative real-time PCR analysis of ATF6, PERK and IRE1 in renal tissue (n = 6 each). The expression level in the Control group was assigned a value of 1. Data are expressed as means ± SEM. *p < 0.05, **p < 0.01. (B) Immunohistochemical staining of CHOP and caspase3 in renal tissue. Scale bars = 50 μmBack to article page
