Abstract

UNLABELLED: Intracellular glucose and lipid metabolism was studied in 12 identical twin pairs discordant for non-insulin-dependent (Type 2) diabetes mellitus (NIDDM) and 13 control subjects without family history of diabetes during low (baseline) and high plasma insulin concentrations, using the hyperinsulinaemic clamp technique combined with indirect calorimetry, tritiated water glycolytic flux rates and biopsy skeletal muscle glycogen synthase activity determinations. Baseline and insulin stimulated rates of lipid oxidation were elevated--and glucose oxidation decreased--in the NIDDM twins compared with the non-diabetic co-twins and controls (all p < 0.05). Baseline and insulin stimulated ..
