BACKGROUND Of the cells that compose the atherosclerotic plaque, vascular endothelial cells are the most resistant to cholesterol accumulation. Cholesterol efflux pathways may play an important role in endothelial cholesterol homeostasis. METHODS AND RESULTS We examined the global genetic response of endothelial cells to cholesterol and in particular the contribution of the cholesterol efflux...

Background: The aim of this research was to investigate the effect of aquatic aerobic training on regulatory factors related to Reverse Cholesterol Transport in women after coronary artery bypass grafting (CABG). Methods: 24 middle-aged women were studied after coronary artery bypass grafting (12 were in control group and 12 in aquatic aerobic training group)....

The fbpABC operon in Neisseria gonorrhoeae encodes an ATP-binding cassette transporter required for iron uptake from the host ferric binding proteins. The gene for the nucleotide-binding domain (fbpC) expressed in Escherichia coli has intrinsic ATPase activity (0.5 mmol/min/mg) uncoupled from the iron transport process. The FbpC E164D mutant is found to have a 10-fold reduction in specific acti...

Elevated expression of the drug efflux transporter ABCG2 seems to correlate with multidrug resistance of cancer cells. Specific COX-2 inhibitor celecoxib has been shown to enhance the sensitivity of cancer cells to anticancer drugs. To clarify whether ABCG2 inhibition is involved in the sensitizing effect of celecoxib, we investigated whether the expression of ABCG2 in breast cancer cell lines ...
