Bile salts of frogs: a new higher bile acid, 3 alpha, 7 alpha, 12 alpha, 26-tetrahydroxy-5 beta-cholestanoic acid from the bile Rana plancyi.
Bile salts of ten species of frogs of the family Ranidae were examined by means of thin-layer chromatography, gas-liquid chromatography, and gas-liquid chromatography-mass spectrometry. Their major bile alcohols were ranol, cyprinol, or bufol. Four species of frogs contained lesser amounts of higher bile acids, and in two species C24 bile acids were present. A higher bile acid that has not been...
متن کاملAppearance of atypical 3 alpha,6 beta,7 beta,12 alpha-tetrahydroxy-5 beta-cholan-24-oic acid in spgp knockout mice.
Bile formation and its canalicular secretion are essential functions of the mammalian liver. The sister-of-p-glycoprotein (spgp) gene was shown to encode the canalicular bile salt export protein, and mutations in spgp gene were identified as the cause of progressive familial intrahepatic cholestasis type 2. However, target inactivation of spgp gene in mice results in nonprogressive but persiste...
متن کاملBiliary bile acids, bile alcohols, and sterols of Alligator mississippiensis.
Bile from Alligator mississippiensis was found to contain a mixture of more than twenty bile acids, bile alcohols, and neutral sterols. Bile acids and bile alcohols were purified by reversed-phase high performance liquid chromatography and thin-layer chromatography. Concentrations were measured by gas-liquid chromatography on 1% HiEFF-8BP and identifications were made by mass spectrometry. The ...
متن کاملThe minor bile acids of the toad, Bufo vulgaris formosus.
Bile from the toad, Bufo vulgaris formosus, was found to contain a number of minor bile acids along with two major bile acids, 3 alpha, 7 alpha, 12 alpha-trihydroxy-5 beta-cholest-22-ene-24-carboxylic acid and 3 alpha, 7 alpha, 12 alpha-trihydroxy-5 beta-cholest-23-en-26-oic acid. The following minor bile acids were identified by combined gas-liquid chromatography-mass spectrometry: cholic acid...
متن کاملAlpha E beta 7.
alpha E beta 7 is a member of the integrin family and is expressed almost exclusively by cells of the T lymphocyte lineage in mucosal tissues. Expression is induced by transforming growth factor beta in the mucosal microenvironment. Genetic elements that control transcription are under investigation and may prove valuable for directing the expression of transgenes in mucosal T cells. The only k...
