Purpose: To clarify the molecular pathophysiology of diabetic retinopathy (DR), we performed comprehensive gene expression analysis of the mouse retina under diabetic conditions with an in-house cDNA microarray. Methods: We prepared a microarray harboring 2,880 cDNAs derived from a mouse retina. Amplified cRNAs of diabetic and age-matched control mouse retinas at 1 and 3 months after intraperitoneal injection of streptozotocin were subjected to array analysis. Results: Genes significantly up-regulated in the diabetic state were listed, and they included a number of genes for oxidative phosphorylation in mitochondoria. Conclusions: Our finding of up-regulation of genes for oxidative phosphorylation in the diabetic retina differs from recently reported findings of down-regulation of these genes in the skeletal muscle of diabetic mice. The diabetic retina seems to be in a potentially activated state for glucose metabolism, presumably because of an increase in insulin-independent glucose influx.
