Role of CoA and acetyl-CoA in regulating cardiac fatty acid and glucose oxidation.

abstract：:Inflammation and dyslipidaemia both play important roles in the development of glomerular atherosclerosis in renal diseases. We have demonstrated that inflammatory mediators induced Scr (scavenger receptor) expression and the formation of foam cells, and that AP-1 (activator protein 1)/ets were necessary transcription...
