Cholestyramine
Based on 9 publication(s) in Google Scholar
Cholestyramine (Cholestyramine resin) is an orally active bile acid sequestrant. Cholestyramine upregulates the expression of intestinal Apical sodium-dependent bile acid transporter and hepatic Cholesterol 7α-hydroxylase. Cholestyramine induces the expression of intestinal and hepatic cholesterol synthesis genes as well as hepatic lipogenesis genes, and promotes bile acid- and neutral sterol-mediated reverse cholesterol transport. Cholestyramine reduces intestinal cholesterol absorption and induces cholesterol efflux. Cholestyramine is applicable to research related to coronary artery disease, atherosclerotic cardiovascular disease and atherosclerosis.

Cholestyramine (0.1-50 μg/mL; 48 h) dose-dependently enhances cholesterol efflux from HMEC-1 immortalized human microvascular endothelial cells, with a 66% reduction in cholesterol load at 50 μg/mL after 48-hour incubation[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Co-administration of cholestyramine (2%; oral via diet; ad libitum access; 4 weeks) and GSPE (250 mg/kg; oral; single dose) in normolipidemic male C57BL/6 mice synergistically enhances the expression of hepatic bile acid synthesis genes, attenuates the cholestyramine-induced upregulation of hepatic cholesterol and lipogenesis gene expression, and reduces serum triglyceride levels more significantly than cholestyramine alone[1].
Cholestyramine (2% (w/w); administered orally via diet; daily; for 14 days) increases the level of macrophage-to-feces reverse cholesterol transport in wild-type C57BL/6J mice by 3.6-fold within 24-48 h by enhancing fecal excretion of bile acids and neutral sterols; no additive effect is observed when it is used in combination with rHDL[2].
