Insulin Sensitizers on Mitochondrial ATP Production and Mitochondrial ATP Production and Mitochondrial Protein Synthesis on Insulin Resistant Type 2 Diabetes and Obesity
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).
The purpose of this study is to determine the efficacy of pioglitazone, twice daily (BID), combined with metformin versus pioglitazone taken alone and metformin taken alone in treating Typ...
The purpose of this study is to determine the efficacy of pioglitazone and metformin combination therapy, once daily (QD), on glycosylated hemoglobin in adults with type 2 diabetes.

The study aims to see if there is any significant difference in the cardiovascular outcomes in type 2 diabetes patients who are treated with pioglitazone or Metformin
The current study investigates Welchol as add-on therapy to pioglitazone to improve glycemic control in subjects with Type 2 Diabetes Mellitus not adequately controlled with pioglitazone m...
This study compared the glycemic effectiveness of three metformin-based dual therapies according to baseline hemoglobin A1c (HbA1c) to evaluate the appropriateness of the guideline enforced by the Nat...
Fetuin-A, a circulating glycoprotein synthesized in the liver, is involved in insulin resistance and type 2 diabetes. However, regulation of fetuin-A synthesis has remained obscure. We previously repo...
To (i) evaluate the prescribing patterns of metformin in patients with type 2 diabetes mellitus (T2DM) and determine the prevalence of contraindications to its use, especially renal impairment, and (i...
Context: Long-term metformin use has been hypothesized to cause B12 deficiency and neuropathy in Type 2 diabetes patients. However, there is a paucity of Indian data regarding the same. Aim: To compar...
Metformin is a first-line antidiabetic drug for type 2 diabetes (T2D) with a relatively good safety profile. Metformin activates AMP-activated protein kinase (AMPK), which is crucial in maintaining re...
