Involvement of ER stress and associated apoptosis signaling pathways in the cardioprotective effects of 4-PBA. (A) The expression levels of Grp78, p-PERK, PERK, CHOP, Bax, Bcl-2, p-JNK, and JNK were detected by immunoblotting assay. The normalized relative levels of Grp78 (B), p- PERK (C), CHOP (D), Caspase-12 (E), Bax (F), and p-JNK (G) were determined by densitometry. The results are represented as means ±SD from 3 independent experiments (n=3). # p<0.05 versus untreated control group; ## p<0.01 versus untreated control group; ### p<0.001 versus untreated control group; * p<0.05 versus I/R-impaired group; ** p<0.01versus I/R-impaired group; *** p<0.001 versus I/R-impaired group.
