M any clinical and epidemiological studies, as well as meta-analyses thereof, have shown the inverse relationship of high-density lipoprotein cholesterol (HDL-C) and apoliopoprotein (apo) A-I plasma levels with the risk of coronary artery disease. HDL particles and their protein and lipid components exert diverse antioxidative, antiinflammatory, antithrombotic, and cytoprotective effects in vit...

background: saponins identified from fenugreek (trigonella foenum-graecum) seeds are reported effective on dyslipidemia. however, the definite mechanism is still not elucidated systematically. in this study, we evaluate the effects of saponin extract on cholesterol absorption, metabolism, synthesis, and reverse cholesterol transport in vivo. methods: saponin extract was prepared according to a ...

BACKGROUND Abundant data indicate that overexpression of apolipoprotein A-I (apoA-I) in mice inhibits atherosclerosis. One mechanism is believed to be promotion of reverse cholesterol transport, but no direct proof of this concept exists. We developed a novel approach to trace reverse transport of labeled cholesterol specifically from macrophages to the liver and feces in vivo and have applied ...
