Abstract
The nuclear receptor peroxisome proliferator-activated receptor γ(PPARγ) is a ligand-dependent transcription factor that controls the expression of specific target genes involved in adipogenesis, inflammatory responses, and lipid metabolism. Atherosclerotic plaque progression is influenced by intraplaque inflammation and extracellular matrix deposition. Anti-inflammatory, anti-proliferative and antiprotease activity of PPARγ may modulate the atherosclerotic process. PPARγ is expressed in atherosclerotic lesions of human coronary arteries and has direct anti-inflammatory effects in the vascular wall. Thiazolidinediones (TZD) are ligands for PPARγ used therapeutically to enhance insulin-mediated glucose uptake in persons with type 2 diabetes. These agents may also exert anti-atherogenic effects on cells of the vessel wall including macrophages, vascular endothelium and vascular smooth muscle. This review discusses the impact of PPARγ and its activators in the numerous processes involved in the formation of atherosclerotic lesions. We provide an overview of in vitro and in vivo data in cell lines, animal models, and humans demonstrating the ways in which PPARγ activation alters the biology of the arterial wall.

Chalcogen-modified nucleic acid analogues
Chalcogen-modified nucleosides, nucleotides and oligonucleotides have been of great interest to scientific research for many years. The replacement of oxygen in the nucleobase, sugar or phosphate backbone by chalcogen atoms (sulfur, selenium, tellurium) gives these biomolecules unique properties resulting from their altered physical and chemical properties. The continuing interest in ...read more
