Decreased levels of metabolic enzymes in pancreatic islets of patients with type 2 diabetes
Open accessAbstract
Aims/hypothesis Glucose-stimulated insulin secretion is defective in patients with type 2 diabetes. We sought to acquire new information about enzymes of glucose metabolism, with an emphasis on mitochondrial enzymes, by comparing pancreatic islets of type 2 diabetes patients with those of non-diabetic controls.Methods Expression of genes encoding 13 metabolic enzymes was estimated with microarrays and activities of up to nine metabolic enzymes were measured.Results The activities of the mitochondrial enzymes, glycerol phosphate dehydrogenase, pyruvate carboxylase (PC) and succinyl-CoA:3-ketoacid-CoA transferase (SCOT) were decreased by 73%, 65% and 92%, respectively, in the diabetic compared with the non-diabetic islets. ATP citrate lyase, a cytosolic enzyme of the mitochondrial citrate pyruvate shuttle, was decreased 57%. Activities of propionyl-CoA carboxylase, NADP-isocitrate dehydrogenase, cytosolic malic enzyme, aspartate aminotransferase and malate dehydrogenase were not significantly different from those of the control. The low activities of PC and SCOT were confirmed with western blots, which showed that their protein levels were low. The correlation of relative mRNA signals with enzyme activities was good in four instances, moderate in four instances and poor in one instance. In diabetic islets, the mRNA signal of the islet cell-enriched transcription factor musculoaponeurotic fibrosarcoma oncogene homologue A, which regulates expression of islet genes, including the PC gene, was decreased to 54% of the control level. PC activity and protein levels in the non-diabetic islets were significantly lower than in islets from non-diabetic rodents.Conclusions/interpretation Low levels of certain islet metabolic enzymes, especially mitochondrial enzymes, are associated with human type 2 diabetes.

“Chronic hyperglycemia is also associated with marked changes in expression of metabolic genes in mouse β-cells (97) and similar changes are observed in islets from individuals with T2DM (409, 430, 606).”

In the citing paper
“Additionally, analysis of insulin-secreting pancreatic β-cells and islets from patients with T2DM showed alterations in mitochondrial physiology, such as hyperpolarization of the mitochondrial membrane and decreased activities of the enzymes glycerol phosphate dehydrogenase, pyruvate carboxylase and succinyl-CoA–3-ketoacid-CoA transferase147,148.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
