DHA induces UPR in hPASMC. (A) Quantitative RT-PCR measurement of HSPA5 gene expression (n = 4). (B) Representative Western blot detection of phosphorylated eIF2α. Total eIF2α served as loading control. (C) Densitometric evaluation of eIF2α phosphorylation (n = 4). (D) Representative PCR detection of XBP-1 splice variant. Data are given as means ± SEM. *P < 0.05 vs corresponding vehicle (veh) control group.
