Taken together, our data suggest that OPG expression is a novel PPAR gamma target gene in VSMC and downregulation of OPG expression by PPAR gamma activation provides a new insight into the understanding of the role of PPAR gamma in atheroscelrosis and hypertension.
The data suggest a contribution of the Pro12Ala polymorphism of PPARgamma to genetic susceptibility to type 2 diabetes mellitus and hypertension, but not to insulin sensitivity in hypertensive subjects.
The combination of small birth size and the Pro12Pro variant of the peroxisome proliferator-activated receptor-gamma 2 (PPAR-gamma 2) gene has been shown to be associated with insulin resistance, which is linked to hypertension.
However, a new mouse model that expresses the analog of a human PPARG mutation displays minimal lipodystrophy and insulin resistance but rather severe hypertension.
The Gly482Ser polymorphism in the peroxisome proliferator-activated receptor-gamma coactivator-1 gene is associated with hypertension in type 2 diabetic men.
The Pro12Ala and the 4a/b polymorphisms of the peroxisome proliferator-activated receptor gamma (PPARgamma) and the endothelial nitric oxide-synthase (eNOS) genes, respectively, have been associated with hypertension in some but not all studies.
Rare monogenic mutations in PPARgamma have a limited impact on the health of the population due to their low frequency but are associated with severe phenotypes such as severe insulin resistance, partial lipodystrophy, type 2 diabetes and hypertension.
Polymorphisms of the peroxisome proliferator-activated receptor-gamma coactivator-1alpha gene are associated with hypertrophic cardiomyopathy and not with hypertension hypertrophy.
Angiotensin II receptor blockers with the ability to selectively modulate activity of peroxisome proliferator-activated receptor-gamma and expression of genes in these fat metabolism pathways may represent useful prototypes for a new class of transcription modulating drugs aimed at treating patients with hypertension and the metabolic syndrome.
Our findings suggest that PPAR-gamma may be a key regulator of blood-brain barrier permeability and a potential therapeutic target during hypertension.
