Figure 2. Effects of HOG-LDL on apoptosis of human retinal capillary pericytes. Highly oxidized-glycated low density lipoprotein (HOG-LDL) at all doses, except 10 mg/l, significantly increased apoptotic rate compared to serum-free medium (SFM). The asterisk indicates p<0.05 compared to SFM; n=3. Squares regression also showed a dose-dependent effect of HOG-LDL (below 50 mg/l) on survival of human retinal capillary pericytes.
