Targeted deletion of the ileal bile acid transporter eliminates enterohepatic cycling of bile acids in mice.
The ileal apical sodium bile acid cotransporter participates in the enterohepatic circulation of bile acids. In patients with primary bile acid malabsorption, mutations in the ileal bile acid transporter gene (Slc10a2) lead to congenital diarrhea, steatorrhea, and reduced plasma cholesterol levels. To elucidate the quantitative role of Slc10a2 in intestinal bile acid absorption, the Slc10a2 gen...
متن کاملInflammatory bowel disease alters intestinal bile acid transporter expression.
The enterohepatic circulation of bile acids (BAs) critically depends on absorption of BA in the terminal ileum and colon, which can be affected by inflammatory bowel disease (IBD). Diarrhea in IBD is believed to result in part from BA malabsorption (BAM). We explored whether IBD alters mRNA expression of key intestinal BA transporters, BA detoxifying systems, and nuclear receptors that regulate...
متن کاملCholesterol modulates human intestinal sodium-dependent bile acid transporter.
Bile acids are efficiently absorbed from the intestinal lumen via the ileal apical sodium-dependent bile acid transporter (ASBT). ASBT function is essential for maintenance of cholesterol homeostasis in the body. The molecular mechanisms of the direct effect of cholesterol on human ASBT function and expression are not entirely understood. The present studies were undertaken to establish a suita...
متن کاملMaternal bile acid transporter deficiency promotes neonatal demise
Intrahepatic cholestasis of pregnancy (ICP) is associated with adverse neonatal survival and is estimated to impact between 0.4 and 5% of pregnancies worldwide. Here we show that maternal cholestasis (due to Abcb11 deficiency) produces neonatal death among all offspring within 24 h of birth due to atelectasis-producing pulmonary hypoxia, which recapitulates the neonatal respiratory distress of ...
متن کاملDiminished gene expression of ileal apical sodium bile acid transporter explains impaired absorption of bile acid in patients with hypertriglyceridemia.
Patients with type IV hyperlipoproteinemia, particularly those with familial hypertriglyceridemia (FHT), have impaired absorption of bile acid, a defect that may contribute to the hypertriglyceridemia ( J. Lipid Res. 1995. 36: 96;-107). To determine whether this absorption defect is a result of abnormal expression of the ileal apical sodium bile acid transporter (ASBT) gene, we biopsied the ter...
