What is Pro12Ala?

Peroxisome proliferator-activated receptor (PPAR)-gamma is a transcription factor with a key role in adipocyte differentiation. The Ala allele of the common Pro12Ala polymorphism in the isoform PPAR-gamma2 is associated with reduced risk for type 2 diabetes.

What does PPAR gamma do?

PPAR-gamma decreases the inflammatory response of many cardiovascular cells, particularly endothelial cells. PPAR-gamma activates the PON1 gene, increasing synthesis and release of paraoxonase 1 from the liver, reducing atherosclerosis.

How do PPARs work?

Activation of PPAR-γ causes insulin sensitization and enhances glucose metabolism, whereas activation of PPAR-β/δ enhances fatty acids metabolism. Thus, PPAR family of nuclear receptors plays a major regulatory role in energy homeostasis and metabolic function.

What is PPARs function?

PPARs are members of the supergene family of nuclear receptors that function as transcription factors regulating the expression of genes involved in cellular intermediary metabolism and inflammation.

Which drugs are TZDs?

There are two thiazolidinediones, rosiglitazone, and pioglitazone, currently approved by the FDA as monotherapy or combined with metformin or sulfonylureas to manage type 2 diabetes mellitus. These medications should be in conjunction with lifestyle modifications such as diet, exercise, and weight reduction.

Is metformin a thiazolidinedione?

At present, two classes of drugs are used as insulin sensitizers: biguanides (metformin), and thiazolidinediones (rosiglitazone and pioglitazone).

Where are PPARs located?

Expression of PPARs in specific tissues. PPARγ is expressed in white and brown adipose tissue, the large intestine and spleen. However, its expression is highest in adipocytes and it plays a key role in the regulation of adipogenesis, energy balance, and lipid biosynthesis [14, 16-18].

How can I increase my PPAR?

Natural Ways to Increase PPAR Gamma

  1. Curcumin found in turmeric [76]
  2. Cinnamon [77]
  3. EGCG or tea [45]
  4. Catechins in tea – increase expression [78, 79]
  5. Oregano/Biochanin A [45], Carvacrol [45]
  6. Silymarin (4.5% isosilybin A) [80]
  7. Butyrate increases expression in humans [81, 12, 44]
  8. Lipoic Acid [82]

What is the importance of PPAR?

PPARs regulate T cell differentiation and function. Signals mediated via PPARs regulate the development, differentiation and function of T cells. PPARγ has an indispensable role in the differentiation of Treg cells in the visceral adipose tissue (VAT) [71] (Fig.

Does metformin have TZD in it?

TZDs help with blood sugar control and insulin resistance. Actos is the only TZD that is currently available in the U.S. It is sometimes prescribed alone, but more commonly is prescribed in addition to another diabetes medication, such as metformin. Actos is used in combination with diet and exercise.

Is januvia a TZD?

Januvia, known chemically as sitagliptin, belongs to a new class of diabetes medicines called DPP-4 inhibitors. Actos belongs to the older, widely used thiazolidinedione, or TZD, class of drugs for the growing type 2 diabetes epidemic.
