Fig 1: FABP4 inhibitor BMS309403 attenuates ER stress in cardiomyocytes exposed to hypoxia. (A, B) H9c2 cardiomyocytes were cultured under normoxia or hypoxia condition for 24 h in the presence or absence of 50 µM BMS309403. The protein expressions of GPR78, CHOP and caspase-12 (A), and p-PERK, PERK, p-eIF2a, eIF2 and ATF4 (B) were determined by Western blot analysis. ß-actin is the internal control. The quantification analysis of protein expression is shown in the right. Student's t test (n = 3). **, P < 0.01
