To test this hypothesis, we determined whether sustained ARF6 activation promotes cholesterol removal from U18666A-treated cells and measured ABCA1-mediated cholesterol efflux.
Decreased ACT binding and clustering after cholesterol removal from erythrocytes was reported by Votjova et al. [40].
Elevated cholesterol biosynthesis does not result in higher liver or plasma levels, because CAR also up-regulates cholesterol removal pathways.
The reason for MARCKS detaching from membranes after cholesterol removal remains unclear.
As expected, cholesterol addition activated LXR target genes and repressed SREBP target genes, whereas cholesterol removal inhibited LXR target genes and induced SREBP target genes.
It has been proposed that increased ACAT activity, may contribute to cholesterol removal from endoplasmic reticulum by promoting the cholesterol esterification rate [ 36].
For cholesterol removal, 0.12 g methyl-beta cyclodextrin was dissolved in 10 mL MEM (10 m m).
7-Alpha cholesterol hydroxylase (CYP7A1) is the first enzyme of classic conversion pathway leading from cholesterol to bile acids synthesis, which is the main way of cholesterol removal from the body [ 2].
The heterodimeric sterol transporter ABCG5/8 determines hepatobiliary cholesterol secretion and cholesterol efflux out of the enterocytes back into the intestinal lumen, thereby promoting net cholesterol removal from the body [ 19- 21].
For patients suffering from familial hypercholesterolemia, LDL-cholesterol removal may be achieved by cascade filtration in an extracorporeal process.
