Peroxisome Proliferator-Activated Receptor

Peroxisome proliferator - activated receptor

The peroxisome proliferator-activated receptors (PPARs) belong to the nuclear hormone receptor superfamily. All PPARs heterodimerize with the retinoid X receptor (RXR) and bind to specific regions on the DNA of target genes. The discovery of PPARγ as a target of multimodal insulin sensitizers has attracted remarkable scientific interest and had a great impact on the pharmaceutical industry. Thi...

Peroxisome Proliferator-Activated Receptor

Peroxisome proliferator-activated receptor-gamma ligands inhibit choroidal neovascularization.

PURPOSE To determine the antiangiogenic effects of peroxisome proliferator-activated receptor (PPAR)-gamma agonists on ocular cells involved in the pathogenesis of choroidal neovascularization (CNV) in vitro and on experimental laser photocoagulation-induced CNV in vivo. METHODS PPAR-gamma expression in human retinal pigment epithelial (RPE) cells and bovine choroidal endothelial cells (CECs)...

Peroxisome Proliferator-Activated Receptor-g Ligands Inhibit Choroidal Neovascularization

METHODS. PPAR-g expression in human retinal pigment epithelial (RPE) cells and bovine choroidal endothelial cells (CECs) was determined using an RNase protection assay and Western blot analysis. Two PPAR-g ligands, troglitazone (TRO) and rosiglitazone (RSG; 0.1–20 mM), were used to assess effects on RPE and CEC proliferation and migration and CEC tube formation in response to vascular endotheli...
