The Role of FXR in Disorders of Bile Acid Homeostasis

WebFarnesoid X receptor (FXR) is a key nuclear transcription factor in regulating bile acid (BA) homeostasis (Byun et al., 2024). In liver, FXR can inhibit 7-α-hydroxylase (CYP7A1) expression, thereby inhibiting the synthesis of BA ( Duan et al., 2024 ). WebMar 9, 2015 · Intriguingly, bile acids also function as nutrient signaling molecules through activation of farnesoid X receptor (FXR), a bile acid-sensing nuclear receptor that regulates lipid, cholesterol, and glucose metabolism 12. FXR is highly expressed in the liver and the intestines, and is also found in kidney and adrenal glands. ... shannen koostachin elementary school staff

FXR, a bile acid receptor and biological sensor - PubMed

WebFXR was shown to regulate cholesterol metabolism in two ways: (1) chenodeoxycholic acid (CDCA), a primary bile acid, binds directly to and activates FXR, which then mediates the feedback suppression by bile acids of cholesterol 7 alpha-hydroxylase (CYP7A1), the rate-limiting enzyme in bile acid biosynthesis from cholesterol; and (2) FXR … WebFXR is mainly expressed in liver, intestine, kidneys, and adrenal gland, with less expression in adipose tissue and heart ().FXR was originally identified as a receptor for the cholesterol precursor farnesol, but is now recognized as the primary receptor for bile acid (3, 6).The bile acid–FXR interaction plays an integral role in regulating hepatic inflammation and … WebFarnesoid X receptor (FXR) regulates bile acid (BA) synthesis in a tissue-specific manner. In the intestine, FXR activation induces fibroblast growth factor (FGF)15/19, which can go to the liver and activate the FGFR4/β-klotho dimer to activate signaling pathways in order to inhibit the expression of genes in the classical BA synthesis pathway. shannen heartz
