Since a crosstalk between AGE and angiotensin II (Ang II) has been proposed in the pathogenesis of accelerated atherosclerosis in diabetes, we examined here whether and how telmisartan, a unique Ang II type 1 receptor blocker (ARB) with peroxisome proliferator-activated receptor-gamma (PPAR-gamma)-modulating activity, could inhibit AGE-induced CRP expression in a human hepatoma cell line, Hep3B cells.
Peroxisome proliferator-activated receptor gamma-2 gene (PPARγ2) rs1801282 (Pro12Ala) polymorphism has been associated with lower risk of metabolic disturbance and atherosclerosis.
The interaction result for S(I) was replicated by the Insulin Resistance Atherosclerosis Family Study (P = 0.018) in their San Antonio sample (n = 484) where subjects with at least one PPARG2 Ala allele and homozygous for the HNF4A rs2144908 A allele had a 29% higher S(I) compared with individuals with at least one G allele.
The Pro12Ala and C161T polymorphisms in peroxisome proliferator-activated receptor γ (PPARγ) have been shown to be associated with carotid artery atherosclerosis.
Recent advances on the emerging role of CD36 and GHRP hexarelin in regulating PPARγ downstream actions with benefits on atherosclerosis, hepatic cholesterol biosynthesis and fat mitochondrial biogenesis are summarized here.
Peroxisome proliferator-activated receptor-γ (PPARγ), liver X receptor-α (LXRα), and PPARγ co-activator-1α (PGC-1α) are nuclear factors that regulate lipid metabolism and inflammation implicated in atherosclerosis.
In addition, PPARγ antagonist GW9662 co-administration mostly blocked these effects, suggesting the important role of PPARγ pathways in mediating 20(S)-Rg3 effects in macrophage polarization and atherosclerosis progression.
Peroxisome proliferator-activated receptor gamma (PPAR gamma) is a nuclear receptor that has been suggested to play protective roles in the pathogenesis of diseases that are characterized by chronic inflammation, such as atherosclerosis.
Adipocytokines such as tumor necrosis factor-alpha (TNF-α), C-reactive protein (CRP), adiponectin, leptin, resistin along with peroxisome proliferator activated receptor-γ (PPAR-γ) are important mediators in glucose homeostasis in association with CD36 and can be used as markers for T2DM and atherosclerosis.
Peroxisome proliferator-activated receptor gamma (PPAR<sub>γ</sub>) has recently been identified as an attractive target for atherosclerosis intervention.
Aortic wall shows histopathological evidence of atherosclerosis in obesity group which is more evident in atherosclerotic group, and milder changes upon receiving PPARγ agonist.
Peroxisome proliferator-activated receptor gamma (PPAR gamma) is a nuclear receptor involved in such cellular processes as adipogenesis, inflammation, atherosclerosis, cell cycle control, apoptosis, and carcinogenesis.
For the first time we demonstrate that CRP modulates PPAR-gamma and its effector genes and reinforces the mechanistic link of CRP as a possible mediator in atherosclerosis and also advocate atorvastatin as a therapeutic modality.
We explored whether TNF-α could promote atherosclerosis by increasing the transcytosis of lipoproteins (e.g., LDL) across endothelial cells and how NF-κB and PPAR-γ were involved in this process.
Nifedipine induces peroxisome proliferator-activated receptor-gamma activation in macrophages and suppresses the progression of atherosclerosis in apolipoprotein E-deficient mice.
In early lesions, PPARG was identified as a specific master regulator of the PCL-responsive atherosclerosis TF-regulatory network, whereas in mature and advanced lesions, the specific master regulators were MLL5 and SRSF10/XRN2, respectively.
Macrophage foam cell formation by oxidized low-density lipoprotein (oxLDL) is a key step in the progression of atherosclerosis, which is involved in cholesterol influx and efflux in macrophages mediated by related proteins such as peroxisome proliferator-activated receptor γ (PPARγ), CD36, PPARα, liver-X receptor α (LXRα), and ATP-binding cassette transporter A1 (ABCA1).
Peroxisome proliferator-activated receptor gamma induces apoptosis and inhibits autophagy of human monocyte-derived macrophages via induction of cathepsin L: potential role in atherosclerosis.
It is of great interest to understand the stereochemical selectivity of 20(R/S)-Rg3 and explore whether differential PPARγ activation by Rg3 stereoisomers, if it exists, could lead to differential physiological outcome and therapeutic effects in diabetic atherosclerosis.
