Perturbation of glucose metabolism in neurons during diabetes favors an upregulation in aldose reductase, the enzyme responsible for sorbitol production. (a) Schematic of sorbitol and fructose biosynthesis during excess glucose conditions. (b) Gene expression of key metabolic enzymes in day 42 co-culture: aldose reductase (AKR1B1) and sorbitol dehydrogenase (SORD). Protein kinase D2 (PRKD2) expression as a key regulator of proliferation. n = 3, *p < 0.05 as determined by a one-way ANOVA.
