Role of mitochondrial dynamics proteins in the pathophysiology of obesity and type 2 diabetes
Abstract
Mitochondrial dysfunction has been reported in skeletal muscle of obese subjects and of type 2 diabetic patients. Reduced mitochondrial mass and defective activity have been proposed to explain this dysfunction. Alterations in mitochondrial function may be crucial to explain the metabolic changes and insulin resistance that characterize both obesity and type 2 diabetes. Consequently, the identification of the primary mechanisms involved is of great relevance. Mitochondrial dynamics refers to the movement of mitochondria along the cytoskeleton and also to the regulation of mitochondrial morphology and distribution, which depend on fusion and fission events. In recent years, some of the proteins that participate in mitochondrial fusion and fission have been identified in mammalian cells. Recent evidence indicates that proteins participating in these processes are also involved in metabolism. The mitochondrial fusion protein mitofusin 2 stimulates respiration, substrate oxidation and the expression of subunits that participate in respiratory complexes in cultured cells. In this regard, skeletal muscle of obese subjects and of type 2 diabetic patients shows reduced mitofusin 2 expression. Therefore, alterations in the activity of the proteins involved in mitochondrial dynamics, and particularly mitofusin 2, may participate in the reduced mitochondrial function present in skeletal muscle in obesity and in type 2 diabetes.

“Further, alterations in mitochondrial dynamics and in particular in Mfn2, have been associated with a reduced mitochondrial function in skeletal muscle in obesity and T2DM (Zorzano et al., 2009) and recently aberrant mitochondrial fission has been also associated with insulin resistance in mouse skeletal muscle (Jheng et al., 2012).”

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.
