Insulin Sensitizers on Mitochondrial ATP Production and Mitochondrial ATP Production and Mitochondrial Protein Synthesis on Insulin Resistant Type 2 Diabetes and Obesity

12:03 EDT 16th April 2014 | BioPortfolio


An association between insulin resistance and mitochondrial dysfunction has been observed in aging, T2D, and in offspring of patients with T2D. It remains to be determined whether pharmacological agents that enhance insulin sensitivity improve muscle mitochondrial function. If these insulin sensitizers improve muscle mitochondrial functions, there are potential therapeutic opportunities to use these drugs to improve mitochondrial dysfunction such as sarcopenia of aging or obesity. Our previous studies demonstrated that insulin stimulates muscle mitochondrial PS and ATP production. It is therefore likely that increasing insulin action stimulates mitochondrial PS and ATP production. If so, these results argue against mitochondrial dysfunction as a cause for insulin resistance. The secondary measurements will demonstrate the underlying mechanism ? whether changes occur at the level of intracellular signaling, transcription or translation. Furthermore, changes in hepatic fat infiltration and endogenous glucose release will be assessed.

Medical and Biotech [MESH] Definitions

A biguanide hypoglycemic agent used in the treatment of non-insulin-dependent diabetes mellitus not responding to dietary modification. Metformin improves glycemic control by improving insulin sensitivity and decreasing intestinal absorption of glucose. (From Martindale, The Extra Pharmacopoeia, 30th ed, p289)

The time period before the development of symptomatic diabetes. For example, certain risk factors can be observed in subjects who subsequently develop INSULIN RESISTANCE as in type 2 diabetes (DIABETES MELLITUS, TYPE 2).

A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.

A severe type of hyperlipidemia, sometimes familial, that it is characterized by the elevation of both plasma CHYLOMICRONS and TRIGLYCERIDES contained in VERY-LOW-DENSITY LIPOPROTEINS. Type V hyperlipoproteinemia is often associated with DIABETES MELLITUS and is not caused by reduced LIPOPROTEIN LIPASE activity as in HYPERLIPOPROTEINEMIA TYPE I .

Urination of a large volume of urine with an increase in urinary frequency, commonly seen in diabetes (DIABETES MELLITUS; DIABETES INSIPIDUS).
