Osteopontin deficiency protects mice from cholesterol gallstone formation by reducing expression of intestinal NPC1L1
Homeostasis of cholesterol is regulated by absorption in the intestine and synthesis in the liver. The authors previously demonstrated that OPN (osteopontin) exhibits the ability to alter hepatic cholesterol metabolism, thus affecting cholesterol gallstone formation in mice. The present study investigated the role of OPN in cholesterol gallstone formation, focusing on its effect on intestinal a...
متن کاملTargeted deletion of Gpbar1 protects mice from cholesterol gallstone formation.
The Gpbar1 [G-protein-coupled BA (bile acid) receptor 1] is a recently identified cell-surface receptor that can bind and is activated by BAs, but its physiological role is unclear. Using targeted deletion of the Gpbar1 gene in mice, we show that the gene plays a critical role in the maintenance of bile lipid homoeostasis. Mice lacking Gpbar1 expression were viable, developed normally and did n...
متن کاملIntestinal CREBH overexpression prevents high-cholesterol diet-induced hypercholesterolemia by reducing Npc1l1 expression
OBJECTIVE The transcription factor cyclic AMP-responsive element-binding protein H (CREBH, encoded by Creb3l3) is highly expressed in the liver and small intestine. Hepatic CREBH contributes to glucose and triglyceride metabolism by regulating fibroblast growth factor 21 (Fgf21) expression. However, the intestinal CREBH function remains unknown. METHODS To investigate the influence of intesti...
متن کاملOsteopontin and integrin are involved in cholesterol gallstone formation
BACKGROUND This study aimed to investigate the role of osteopontin and its receptor, integrin αv, in gallstone formation using human tissue specimens and a guinea pig lithogenic model. MATERIAL/METHODS The nucleation role of osteopontin was determined in patients' and normal gallbladder bile samples in vitro. Normal gallbladder was the control, and gallstone gallbladders were divided into gro...
متن کاملErratum: Osteopontin Deficiency Alters Biliary Homeostasis and Protects against Gallstone Formation
The precipitation of excess biliary cholesterol as solid crystals is a prerequisite for cholesterol gallstone formation, which occurs due to disturbed biliary homeostasis. Biliary homeostasis is regulated by an elaborate network of genes in hepatocytes. If unmanaged, the cholesterol crystals will aggregate, fuse and form gallstones. We have previously observed that the levels of osteopontin (OP...
