Figure 6. Effects of SB203580 on HOG-LDL-induced apoptosis. Administration of 10 µM SB203580, an inhibitor of p38MAPK signaling pathways, did not inhibit highly oxidized-glycated low density lipoprotein (HOG-LDL)-induced apoptosis in human retinal capillary pericytes (HRCP). Bars represent mean±SD of three separate experiments. The asterisk indicates p<0.05 compared to serum-free medium (SFM).
