Overexpression of mitofusin 2 improves translocation of glucose transporter 4 in skeletal muscle of high‑fat diet‑fed rats through AMP‑activated protein kinase signaling.
Open accessAbstract
Mitofusin 2 (Mfn2) is a mitochondrial membrane protein that plays a role in mitochondrial fusion and metabolism in mammalian cells. Previous studies have reported a positive correlation between Mfn2 expression and insulin sensitivity in non‑diabetic and type 2 diabetic subjects. Thus, the aim of the present study was to investigate whether Mfn2 overexpression improves insulin sensitivity of high‑fat diet (HFD) rats and the possible underlying mechanisms. Male SD rats were randomly divided into four groups: negative control; HFD; HFD plus adenoviral vectors; and HFD plus adenoviral vectors encoding Mfn2. Following an 11‑week treatment protocol, the euglycemic‑hyperinsulinemic clamp technique was applied to evaluate insulin sensitivity in rats. The skeletal muscles from rats in each group were analyzed by real‑time PCR and western blot analysis to determine glucose transporter 4 (GLUT4) expression, translocation and relative translocation signaling. Consistent with Mfn2 repression and glucose intolerance, HFD downregulates GLUT4 expression at the mRNA and protein levels, while Mfn2 overexpression activates AMP‑activated protein kinase (AMPK), increases GLUT4 expression and translocation and improves insulin resistance in the skeletal muscles of HFD rats. Results of the present study indicate that Mfn2 overexpression improves insulin sensitivity and may regulate GLUT4 translocation in an AMPK‑dependent manner in the skeletal muscles of HFD rats. This study is likely to provide insight into the unique role of Mfn2 in promoting glucose uptake, leading to modulation of GLUT4 translocation signaling and maintenance of glucose homeostasis in vivo.

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.
