Longitudinal transcriptomic and metabolomic data demonstrate altered lipid metabolism following the onset of hyperglycemia in spontaneously diabetic rats

We hypothesized that a lack of insulin reaching the liver contributes to the metabolic shift towards lipid oxidation observed in humans with type 1 diabetes and rodent models of the disease. To test our hypothesis, we measured changes in the hepatic gene expression and serum metabolome of a BioBreeding rat model of type 1 diabetes before and after the onset of hyperglycemia.
