WebFeb 3, 2016 · Bile acid (BA) metabolism is tightly controlled by nuclear receptor signaling to coordinate regulation of BA synthetic enzymes and transporters. Here we reveal a molecular cascade consisting of... WebBile acids (BAs) are well known for their role in fat absorption (Hofmann, 1963). However, they also act as signaling molecules involved in a variety of pathways that regulate BA, glucose, and lipid homeostasis (Patti et al., 2009; Qi et al., 2015; Watanabe et al., 2011).

WebMay 15, 2004 · Here, we provide evidence in support of the first hypothesis and show that bile acids, by activating FXR, induce the expression of SHP. SHP then interferes with SREBP-1c expression by inhibiting the activity of LXR and eventually other transcription factors that stimulate SREBP-1c expression. Methods. Materials. WebAug 3, 2024 · Bile acid concentrations in samples were determined using standard curves for each bile acid except T-αMCA, T-βMCA and T-ωMCA where TCA was used as a class standard, ...

WebBile acids lower triglyceride levels via a pathway involving FXR, SHP, and SREBP-1c. We explored the effects of bile acids on triglyceride (TG) homeostasis using a combination of molecular, cellular, and animal models. Cholic acid (CA) prevents hepatic TG accumulation, VLDL secretion, and elevated serum TG in mouse models of ... WebSep 1, 2000 · Thus, SHP-1 is likely to regulate its own expression. This feedback regulation may provide a mechanism for attenuating the bile acid–mediated repression of genes by SHP-1. A model for bile acid–mediated repression of gene expression via increased SHP-1 levels is shown in Figure 7. Download : Download high-res image (52KB)
WebJan 25, 2024 · Bile acids (BAs) are synthesized from cholesterol, produced in the hepatocytes, stored in the gallbladder, and secreted into the intestine to facilitate the digestion of lipids and the absorption of triglycerides (TG), cholesterol, and lipid-soluble vitamins ( 7, 8 ). Webwith shp gene activation. Bile acid—mediated down-reg-ulation occurred via fxr-dependent suppression of the ntcp RXR:RAR response element. Moreover, cotrans-fected shp directly inhibited retinoid activation of the ntcp promoter. Conclusions: These studies show nega-tive feedback regulation of ntcp by bile acid—activated fxr via induction of ...
WebDec 1, 2007 · Bile acids are amphiphilic end products of cholesterol catabolism that facilitate lipid absorption in the intestine. Bile acids are synthesized in the liver, released into the proximal intestine, and reabsorbed in the distal intestine ( 1 ).
WebBile acids are amphipathic molecules essential for the absorption of lipids in the intestine.
