Valsartan Attenuated Homocysteine-Induced Impaired Autophagy and ER Stress in Human Umbilical Vein Endothelial Cells

Figure 7

Autophagy inhibition by 3-MA and inhibition of ER stress by 4-PBA inhibited ER stress in HUVECs. (a, b) Representative immunoblots and corresponding densitometry analysis of LC3B, Beclin1, p62, BiP, CHOP, Bax, Bcl2, and cleaved-caspase 3 protein in Hcy-treated HUVECs with or without valsartan or 3-MA. (c, d) Representative immunoblots and corresponding densitometry analysis of BiP, CHOP, Bax, Bcl2, and cleaved-caspase 3 protein in Hcy-treated HUVECs with or without 4-PBA. Data are shown as ; compared with the CTL group; # compared with the Hcy group.
