Endoplasmic Reticulum Stress Regulates Hepatic Bile Acid Metabolism in Mice
BACKGROUND & AIMS Cholestasis promotes endoplasmic reticulum (ER) stress in the liver, however, the effect of ER stress on hepatic bile acid metabolism is unknown. We aim to determine the effect of ER stress on hepatic bile acid synthesis and transport in mice. METHODS ER stress was induced pharmacologically in C57BL/6J mice and human hepatoma (HepG2) cells. The hepatic expression of genes co...
متن کاملBile Acid Synthesis
During biosynthesis of bile acid, carbons 25-26-27 are removed from the cholesterol side-chain. Side-chain oxidation begins either with hydroxylation at the 26-position, in which case the three-carbon fragment is released as propionic acid, or with hydroxylation at the 25-position, in which case the threecarbon fragment is released as acetone. We have previously shown in the rat that the contri...
متن کاملBile acid synthesis in humans.
Metabolic pathways involved in the conversion of cholesterol to cholic and chenodeoxycholic acids have been investigated in bile fistula patients treated with a number of labeled potential bile acid intermediates. The findings of the present report indicate that the human liver cell has the capacity to synthesize both primary bile acids via multiple routes from cholesterol and 7 alpha-hydroxych...
متن کاملBile Acid Synthesis
f Abstract The synthesis and excretion of bile acids comprise the major pathway of cholesterol catabolism in mammals. Synthesis provides a direct means of converting cholesterol, which is both hydrophobic and insoluble, into a water-soluble and readily excreted molecule, the bile acid. The biosynthetic steps that accomplish this transformation also confer detergent properties to the bile acid, ...
متن کاملGlutathione deficiency increases hepatic ascorbic acid synthesis in adult mice.
Glutathione deficiency, induced in adult mice by administering buthionine sulfoximine (an inhibitor of glutathione synthesis), led to a rapid and substantial increase in ascorbate in the liver. This effect was apparent 2-4 hr after giving the inhibitor; subsequently, the level of ascorbate decreased and that of dehydroascorbate increased markedly, supporting the conclusion that glutathione func...
