生物活性

Cholestyramine (Colestyramine) is a bile acid binding resin and can inhibit intestinal bile acid absorption which results in the increasing bile acid synthesis from cholesterol.

体外研究
(In Vitro)

Cholestyramine (0.1-50 μg/mL) produced the most dramatic results after a 24-hour exposure; an efflux rate of 65% compared with control cells. Cholestyramine is an anion-exchange resin and is insoluble in water. alcohol, chloro-form, and ether. For the assay, cholestyramine is initially wetted with a small amount of DMSO further diluting with media. A blank sample prepared with dimethylsulfoxide DMSO without cholestyramine displayed no differences from the control samples^[3].

体内研究
(In Vivo)

Cholestyramine is a bile acid binding resin and can inhibit intestinal bile acid absorption which results in the increasing bile acid synthesis from cholesterol^[1]. Results reveal that GSPE treatment alone, and co-administration with Cholestyramine, regulate BA, cholesterol and TG metabolism differently compare to Cholestyramine administration alone. Notably, GSPE decreases intestinal apical sodium-dependent bile acid transporter (Asbt) gene expression, while Cholestyramine significantly induces expression. Administration with GSPE or Cholestyramine robustly induces hepatic BA biosynthetic gene expression, especially cholesterol 7α-hydroxylase (Cyp7a1), compare to control, while co-administration further enhances expression. Treatment with Cholestyramine induces both intestinal and hepatic cholesterologenic gene expression, while co-administration with GSPE attenuates the Cholestyramine-inducing increase in the liver but not in the intestine. Cholestyramine also induces hepatic lipogenic gene expression, which is attenuated by co-administration with GSPE^[2].

Animal Administration ^[2]	Mice are purchased at 7 weeks of age and allowed to acclimate for one week. At 8-weeks of age the mice are given either a control or a 2% Cholestyramine-supplementing diet for 4 weeks (n=18 per group). Body weight for each mouse is recorded weekly. After 4 weeks, the mice in each group are randomly assigned to one of two treatment groups and orally gavaged with either vehicle (water) or GSPE (250 mg/kg) and terminated 14 hours later (n=9 per experimental group). The four treatment groups are as follows: 1. CON: Control diet for 4 weeks following by oral gavage with vehicle (water) for 14 hrs; 2. GSPE: Control diet for 4 weeks following by oral gavage with 250 mg/kg GSPE for 14 hrs; 3.Cholestyramine 2% Cholestyramine-supplementing diet for 4 weeks following by oral gavage with vehicle for 14 hrs; and 4. Cholestyramine+GSPE: 2% cholestyramine-supplementing diet for 4 weeks following by oral gavage with 250 mg/kg GSPE for 14 hrs. Blood is collected from the orbital plexus under isoflurane anesthesia, and intestines and livers are snap-frozen in liquid nitrogen and stored at -80°C until use. At the start of the 14 hr experiment mice are placed into clean cages, and feces are manually collected at the end of the study^[2]. MCE has not independently confirmed the accuracy of these methods.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
