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

体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
