Downregulation of PPARs and SREBP by acyl-CoA-binding protein overexpression in transgenic rats.

Acyl-CoA-binding protein (ACBP) acts as an acyl-CoA pool former, transporter, and regulator of gene transcription in vitro. We created a transgenic rat line overexpressing ACBP, as the physiological relevance of ACBP in lipid metabolism is unclear. Transgenic rats revealed increased levels of ACBP and significantly elevated acyl-CoA tissue levels while there was no effect on plasma triglyceride, cholesterol, or serum-free fatty acid levels.

VEGF-A, VEGF-D, VEGF receptor-1, VEGF receptor-2, NF-kappaB, and RAGE in atherosclerotic lesions of diabetic Watanabe heritable hyperlipidemic rabbits.

Plaque angiogenesis may be associated with the development of unstable and vulnerable plaques. Vascular endothelial growth factors (VEGFs) are potent angiogenic factors that can affect plaque neovascularization. Our objective was to determine the effect of diabetes on atherosclerosis and on the expression of angiogenesis-related genes in atherosclerotic lesions.
