Basic disturbances in skeletal muscle fatty acid metabolism in obesity and type 2 diabetes mellitus

Abstract

The present article addresses the hypothesis that disturbances in skeletal muscle fatty acid handling in abdominal obesity and type 2 diabetes mellitus may play a role in the aetiology of increased adipose tissue stores, increased triacylglycerol storage in skeletal muscle and skeletal muscle insulin resistance. The uptake and/or oxidation of fatty acids have been shown to be impaired during post-absorptive conditions in abdominally-obese subjects and/or subjects with type 2 diabetes. Also, human studies have shown that muscle of subjects that are (abdominally) obese and/or have type 2 diabetes is characterized by an inability to increase fatty acid uptake and/or fatty acid oxidation during β-adrenergic stimulation and exercise. This disturbance in fat oxidation may promote, on one hand, the development of increased adipose tissue stores and obesity. On the other hand, fatty acids that are taken up by muscle and not oxidized may increase triacylglycerol storage in muscle, which has been associated with skeletal-muscle insulin resistance. Disturbances in the capacity to increase fat oxidation during post-absorptive conditions, β-adrenergic stimulation and exercise in subjects who are obese and/or have type 2 diabetes persist after weight reduction, indicating that the diminished fat oxidation may be a primary factor leading to the obese and/or insulin-resistant state rather than an adaptational response. Clearly, the precise sequence of events leading to an increased adiposity and insulin resistance in obesity and type 2 diabetes mellitus is not yet fully understood.

  • Cross-sectional studies show that isolated muscle strips, tissue homogenates, or cultured myocytes from severely obese and/or diabetic humans oxidize fat more slowly than specimens from healthy controls.

    “cross-sectional studies showing that isolated muscle strips, tissue homogenates or cultured myocytes from severely obese and/or diabetic humans exhibit diminished rates of fat oxidation when compared to specimens derived from healthy control subjects [9,41,46,87].”

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.
