Abstract

Insulin resistance in skeletal muscle and liver may play a primary role in the development of type 2 diabetes mellitus, and the mechanism by which insulin resistance occurs may be related to alterations in fat metabolism. Transgenic mice with muscle- and liver-specific overexpression of lipoprotein lipase were studied during a 2-h hyperinsulinemic–euglycemic clamp to determine the effect of tissue-specific increase in fat on insulin action and signaling. Muscle–lipoprotein lipase mice had a 3-fold increase in muscle triglyceride content and were insulin resistant because of decreases in insulin-stimulated glucose uptake in skeletal muscle and insulin activation of insulin receptor substrate-1-associated phosphatidylinositol 3-kinase activity. In contrast, liver–lipoprotein lipase mice had a 2-fold increase in liver triglyceride content and were insulin resistant because of impaired ability of insulin to suppress endogenous glucose production associated with defects in insulin activation of insulin receptor substrate-2-associated phosphatidylinositol 3-kinase activity. These defects in insulin action and signaling were associated with increases in intracellular fatty acid-derived metabolites (i.e., diacylglycerol, fatty acyl CoA, ceramides). Our findings suggest a direct and causative relationship between the accumulation of intracellular fatty acid-derived metabolites and insulin resistance mediated via alterations in the insulin signaling pathway, independent of circulating adipocyte-derived hormones.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Previous studies by our group and others have demonstrated a strong relationship between triglyceride content in liver and muscle and insulin resistance in these tissues.

    “Previous studies by our group (9, 17-20) and others (7, 21, 22) have demonstrated a strong relationship between triglyceride content in liver and muscle and insulin resistance in these tissues.”
  • Muscle-specific overexpression of lipoprotein lipase leads to accumulation of fat and fatty acyl-CoA in muscle and severe muscle insulin resistance, while fat content and insulin sensitivity in other tissues such as liver remain unchanged.

    “(vi) muscle-specific over expression of lipoprotein lipase leads to the accumulation of fat/FACoA in muscle and severe muscle insulin resistance, while the fat content and insulin sensitivity in other tissues, that is, liver, remain unchanged [78];”

    From Pathogenesis of insulin resistance in skeletal muscle (2010) · cites this paper as [78]

  • Genetic murine models have established that tissue-specific overexpression of lipoprotein lipase promotes tissue-specific lipid accumulation and selective insulin resistance.

    “Genetic murine models have been invaluable in establishing this theory—eg, tissue-specific overexpression of lipoprotein lipase promotes tissue-specific lipid accumulation and selective insulin resistance.47”

    From Lipid-induced insulin resistance: unravelling the mechanism (2010) · cites this paper as [47]

  • NAFLD-induced hepatic insulin resistance is a major factor responsible for the transition from normoglycemia to fasting hyperglycemia and T2DM.

    “recent studies have demonstrated that NAFLD-induced hepatic insulin resistance is a major factor responsible for the transition from normoglycemia to fasting hyperglycemia and T2DM (18–23).”
  • NAFLD is strongly linked to hepatic insulin resistance.

    “NAFLD is strongly linked to hepatic insulin resistance”

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.
