Targeting Ceramide Synthesis to Reverse Insulin Resistance
Insulin resistance is a key feature of type 2 diabetes, and the strong association between fat oversupply and defective insulin action in target tissues, especially skeletal muscle and liver, has motivated the search for intracellular lipid mediators that can interfere with insulin signaling and glucose homeostasis. Two of the best-studied candidates are diacylglycerol (DAG) and ceramide (1–3),...
متن کاملMechanistic interplay between ceramide and insulin resistance
Recent research adds to a growing body of literature on the essential role of ceramides in glucose homeostasis and insulin signaling, while the mechanistic interplay between various components of ceramide metabolism remains to be quantified. We present an extended model of C16:0 ceramide production through both the de novo synthesis and the salvage pathways. We verify our model with a combinati...
متن کاملCeramide and Insulin Resistance: How Should the Issue Be Approached?
There is a growing amount of data indicating that ceramide is involved in the generation of insulin resistance (1–3). However, investigation into the biological function of ceramide is a complex issue. First, there are no ceramide receptors on the plasma membrane. Second, the membrane is impermeable for ceramides containing long-chain fatty acid residues and only such ceramides seem to exist in...
متن کاملDownregulation of lipin-1 induces insulin resistance by increasing intracellular ceramide accumulation in C2C12 myotubes
Dysregulation of lipid metabolism in skeletal muscle is involved in the development of insulin resistance. Mutations in lipin-1, a key lipid metabolism regulator leads to significant systemic insulin resistance in fld mice. However, the function of lipin-1 on lipid metabolism and insulin sensitivity in skeletal muscle is still unclear. Herein we demonstrated that downregulation of lipin-1 in C2...
متن کاملInsulin Resistance, Ceramide Accumulation, and Endoplasmic Reticulum Stress in Human Chronic Alcohol-Related Liver Disease
BACKGROUND Chronic alcohol-related liver disease (ALD) is mediated by insulin resistance, mitochondrial dysfunction, inflammation, oxidative stress, and DNA damage. Recent studies suggest that dysregulated lipid metabolism with accumulation of ceramides, together with ER stress potentiate hepatic insulin resistance and may cause steatohepatitis to progress. OBJECTIVE We examined the degree to...
