Pentraxin 3 promotes oxLDL uptake and inhibits cholesterol efflux from macrophage-derived foam cells.
Wuhan, China. In Exp Mol Pathol, 24 Apr 2014
To evaluate the role of specific signaling pathways, human THP-1 cells were pre-treated with inhibitors of the extracellular signal-regulated protein kinases 1 and 2 (ERK1/2), phosphatidylinositide 3-kinases (PI3-K), and p38 mitogen-activated protein kinase (MAPK) pathways (PD98059, LY294002, and SB203580, respectively), and then exposed to oxLDL for the uptake assay or oxLDL and [(3)H]-cholesterol and apolipoprotein A-I (apoA-I) for the cholesterol efflux assay.
Molecular regulation of cholesterol metabolism: HDL-based intervention through drugs and diet.
Padova, Italy. In Indian J Exp Biol, Nov 2013
Pharmacological interventions mainly involve the use of molecules capable of interfering with high-density lipoprotien (HDL) metabolism and the reverse cholesterol transport (RCT) through genetic control of apolipoprotein A-I (ApoA-I), agonism at liver X-receptor alpha (LXRalpha), or inhibition of cholesteryl ester transport protein (CETP), scavenger receptor BI(SR-BI), and ecto F0F1ATPase/synthase. Nutritional interventions are based on the use of fibres, phytosterols, and probiotics acting through interference with absorption and reabsorption of cholesterol by enterocyte and hepatocyte specific transporters, thus influencing RCT final step.
Control of angiogenesis by AIBP-mediated cholesterol efflux.
San Diego, United States. In Nature, Jul 2013
To prevent cholesterol overload, ATP-binding cassette (ABC) transporters mediate cholesterol efflux from the cells to apolipoprotein A-I (apoA-I) and the apoA-I-containing high-density lipoprotein (HDL).
Lipid-related markers and cardiovascular disease prediction.
In Jama, 2012
OBJECTIVE: To determine whether adding information on apolipoprotein B and apolipoprotein A-I, lipoprotein(a), or lipoprotein-associated phospholipase A2 to total cholesterol and high-density lipoprotein cholesterol (HDL-C) improves cardiovascular disease (CVD) risk prediction.
