In primary cultures of rat hepatocytes, transcription of the cholesterol 7alpha-hydroxylase gene is induced synergistically by glucocorticoid and thyroid hormones. The objective of the present study was to evaluate the role of endogenous glucocortico

Bile salts are surfactants that partition into phospholipid bilayers. When liposomes or membranes are exposed to mixed solutions of bile salts, the more hydrophobic bile salt species associate preferentially with the lipid bilayer. As a consequence,

Tauroursodeoxycholate (TUDC), a relatively hydrophilic bile salt, reduces disruption of cholesterol-rich membranes by more hydrophobic bile salts such as taurocholate (TC), taurochenodeoxycholate (TCDC), or taurodeoxycholate (TDC). We examined the in

Hepatic bile acid synthesis is thought to be under negative feedback control by bile salts in the enterohepatic circulation, acting at the level of cholesterol 7 alpha-hydroxylase (C7 alpha H), the initial and rate-limiting step in the bile acid bios

This paper describes the derivation of a bile salt monomeric hydrophobicity index that quantitatively defines the composite hydrophilic-hydrophobic balance of a mixture of bile salts. The index is based on the logarithms of bile salt capacity factors

We present evidence that ursodeoxycholate prevents toxicity of more hydrophobic bile salts by inhibiting micellar solubilization of membrane lipids. Using both centrifugal ultrafiltration and gel filtration methods we studied leakage of inulin from v

Cholesterol 7 alpha-hydroxylase, the rate-limiting enzyme in the bile acid synthesis pathway, is down-regulated by taurocholate by way of negative feedback control at the level of gene transcription. The molecular basis of regulation of cholesterol 7

Cholesterol 7 alpha-hydroxylase, the rate-limiting enzyme in the bile acid biosynthetic pathway, is thought to be regulated by hydrophobic bile acids through negative feedback control. The role of cholesterol in the regulation of cholesterol 7 alpha-

The role of bile acids in the regulation of cholesterol 7 alpha-monooxygenase (EC 1.14.13.17) was characterized using primary cultures of rat hepatocytes supplemented with dexamethasone and thyroxine. Taurocholate and taurodeoxycholate (50 microM) re
