Ad-MafG treatment resulted in repression of almost all bile acid synthesis genes, including Cyp7b1, Cyp27a1, independent of the diet (Fig. 4C).

    During cholestasis, bile acid-activated signaling regulates bile acid detoxification mechanisms as well as cell survival and proliferation. The hydrophilic bile acid UDCA has been used as the primary cholestasis therapy for decades. Pharmacological agents targeting the bile acid receptors are being developed as novel therapeutics for cholestasis. Standard PDF (813.0 KB) Ancillary Article Information. DOI 10.1002/hep Peter L. M.

    Novel drug targets include the bile BA receptors, farnesoid X receptor and TGR5, the BA-induced gut hormones, п¬Ѓbroblast growth factor 19 and glucagon-like peptide 1, and the BA transport systems, apical sodium-dependent bile acid transporter and Na1-taurocholate cotransport-ing polypeptide, within the enterohepatic circulation. 8-1-2009В В· The next step in BA synthesis is the hydroxylation and oxidation to a carboxylic acid at the C27 position by the mitochondrial CYP27A1 enzyme (Pikuleva et al., 1998), followed by ligation to coenzyme A by the bile acid coenzyme-A synthetase (BAS) (Mihalik et al., 2002).The side chains of these C27 intermediates are then shortened to C24 BAs by ОІ-oxidation in the peroxisomes (Norlin and
