Procyanidin B2 Alleviates Palmitic Acid-Induced Injury in HepG2 Cells via Endoplasmic Reticulum Stress Pathway

Figure 3

PCB2 inhibits ROS formation in PA-induced HepG2 cells. Cells were exposed to PA (125 μM) and treated by PCB2 (2.5, 5, and 10 μM) for 12 h. Intracellular ROS detected with DCFH-DA (green) and relative fluorescence intensity were measured. Scale bar = 50 μm. Typical cells with excessive ROS were marked by white arrows. The data are presented as means ± S.D. ^### < 0.001 vs control,  < 0.01 and  < 0.001 vs model group.
