23BB administration suppressed expression level of ER stress proteins. The expression of GRP78, IRE1α, p-eIF2α, ATF4, CHOP, p-JNK, caspase-12, and XBP1, as measured by immunoblot analysis, in kidney tissue sections in each group. The densitometry values of p-JNK were normalized with JNK. The densitometry values of p-eIF2α were normalized with eIF2α. The densitometry values of other proteins were normalized with β-actin. Data are represented as the means ± SE (n = 6 for each group). ∗P < 0.05.
