Role of mitochondria biogenesis in the metabolic memory associated with the continued progression of diabetic retinopathy and its regulation by lipoic acid.
Improvement of retinal vascular injury in diabetic rats by statins is associated with the inhibition of mitochondrial reactive oxygen species pathway mediated by peroxisome proliferator-activated receptor gamma coactivator 1alpha.
The present study demonstrates that the AA genotype of the Gly482Ser polymorphism in the PPARGC1 gene might be a risk factor for diabetic retinopathy in the Slovene population (Caucasians) with type 2 diabetes (odds ratio 2.7, 95% confidence interval 1.0-6.8), whereas the Pro12Ala polymorphism of the PPARgamma gene failed to confer susceptibility to diabetic retinopathy.
