An allosteric synthetic DNA. (1/334)

Allosteric DNA oligonucleotides are potentially useful diagnostic reagents. Here we develop a model system for the study of allosteric interactions in DNAs. A DNA that binds either Cibacron blue or cholic acid was isolated and partially characterized. Isolation was performed using a multi-stage SELEX. First, short oligos that bind either Cibacron blue or cholic acid were enriched from random oligonucleotide pools. Then, members of the two pools were fused to form longer oligos, which were then selected for theability to bind Cibacron blue columns and elute with cholic acid. One resulting isolate (A22) was studied. Dye- and cholate-binding functions can be separated on sequences from the 5'- and 3'-regions, respectively. Ligand-column affinity assays indicate that each domain binds only its respective ligand. However, the full-length A22 will bind either dye or cholate columns and elute with the other ligand, as if binding by the ligands is mutually exclusive. Furthermore, S1 nuclease protection assays show that Cibacron blue causes a structural change in A22 and that cholic acid inhibits this change. This system will be useful for elucidating mechanisms of allosteric interactions in synthetic DNAs.  (+info)

Cholic acid aids absorption, biliary secretion, and phase transitions of cholesterol in murine cholelithogenesis. (2/334)

Cholic acid is a critical component of the lithogenic diet in mice. To determine its pathogenetic roles, we fed chow or 1% cholesterol with or without 0.5% cholic acid to C57L/J male mice, which because of lith genes have 100% gallstone prevalence rates. After 1 yr on the diets, we measured bile flow, biliary lipid secretion rates, hepatic cholesterol and bile salt synthesis, and intestinal cholesterol absorption. After hepatic conjugation with taurine, cholate replaced most tauro-beta-muricholate in bile. Dietary cholic acid plus cholesterol increased bile flow and biliary lipid secretion rates and reduced cholesterol 7alpha-hydroxylase activity significantly mostly via deoxycholic acid, cholate's bacterial 7alpha-dehydroxylation product but did not downregulate cholesterol biosynthesis. Intestinal cholesterol absorption doubled, and biliary cholesterol crystallized as phase boundaries shifted. Feeding mice 1% cholesterol alone produced no lithogenic or homeostatic effects. We conclude that in mice cholic acid promotes biliary cholesterol hypersecretion and cholelithogenesis by enhancing intestinal absorption, hepatic bioavailability, and phase separation of cholesterol in bile.  (+info)

Antilithiasic effect of beta-cyclodextrin in LPN hamster: comparison with cholestyramine. (3/334)

Beta-Cyclodextrin (BCD), a cyclic oligosaccharide that binds cholesterol and bile acids in vitro, has been previously shown to be an effective plasma cholesterol lowering agent in hamsters and domestic pigs. This study examined the effects of BCD as compared with cholestyramine on cholesterol and bile acid metabolism in the LPN hamster model model for cholesterol gallstones. The incidence of cholesterol gallstones was 65% in LPN hamsters fed the lithogenic diet, but decreased linearly with increasing amounts of BCD in the diet to be nil at a dose of 10% BCD. In gallbladder bile, cholesterol, phospholipid and chenodeoxycholate concentrations, hydrophobic and lithogenic indices were all significantly decreased by 10% BCD. Increases in bile acid synthesis (+110%), sterol 27-hydroxylase activity (+106%), and biliary cholate secretion (+140%) were also observed, whereas the biliary secretion of chenodeoxycholate decreased (-43%). The fecal output of chenodeoxycholate and cholate (plus derivatives) was increased by +147 and +64%, respectively, suggesting that BCD reduced the chenodeoxycholate intestinal absorption preferentially. Dietary cholestyramine decreased biliary bile acid concentration and secretion, but dramatically increased the fecal excretion of chenodeoxycholate and cholate plus their derivatives (+328 and +1940%, respectively). In contrast to BCD, the resin increased the lithogenic index in bile, induced black gallstones in 34% of hamsters, and stimulated markedly the activities of HMG-CoA reductase (+670%), sterol 27-hydroxylase (+310%), and cholesterol 7alpha-hydroxylase (+390%). Thus, beta-cyclodextrin (BCD) prevented cholesterol gallstone formation by decreasing specifically the reabsorption of chenodeoxycholate, stimulating its biosynthesis and favoring its fecal elimination. BCD had a milder effect on lipid metabolism than cholestyramine and does not predispose animals to black gallstones as cholestyramine does in this animal model.  (+info)

Polyspecific substrate uptake by the hepatic organic anion transporter Oatp1 in stably transfected CHO cells. (4/334)

The rat liver organic anion transporting polypeptide (Oatp1) has been extensively characterized mainly in the Xenopus laevis expression system as a polyspecific carrier transporting organic anions (bile salts), neutral compounds, and even organic cations. In this study, we extended this characterization using a mammalian expression system and confirm the basolateral hepatic expression of Oatp1 with a new antibody. Besides sulfobromophthalein [Michaelis-Menten constant (Km) of approximately 3 microM], taurocholate (Km of approximately 32 microM), and estradiol- 17beta-glucuronide (Km of approximately 4 microM), substrates previously shown to be transported by Oatp1 in transfected HeLa cells, we determined the kinetic parameters for cholate (Km of approximately 54 microM), glycocholate (Km of approximately 54 microM), estrone-3-sulfate (Km of approximately 11 microM), CRC-220 (Km of approximately 57 microM), ouabain (Km of approximately 3,000 microM), and ochratoxin A (Km of approximately 29 microM) in stably transfected Chinese hamster ovary (CHO) cells. In addition, three new substrates, taurochenodeoxycholate (Km of approximately 7 microM), tauroursodeoxycholate (Km of approximately 13 microM), and dehydroepiandrosterone sulfate (Km of approximately 5 microM), were also investigated. The results establish the polyspecific nature of Oatp1 in a mammalian expression system and definitely identify conjugated dihydroxy bile salts and steroid conjugates as high-affinity endogenous substrates of Oatp1.  (+info)

Biliary bile acids in primary biliary cirrhosis: effect of ursodeoxycholic acid. (5/334)

Bile acid composition in fasting duodenal bile was assessed at entry and at 2 years in patients with primary biliary cirrhosis (PBC) enrolled in a randomized, double-blind, placebo-controlled trial of ursodeoxycholic acid (UDCA) (10-12 mg/kg/d) taken as a single bedtime dose. Specimens were analyzed by a high-pressure liquid chromatography method that had been validated against gas chromatography. Percent composition in bile (mean +/- SD) for 98 patients at entry for cholic (CA), chenodeoxycholic (CDCA), deoxycholic (DCA), lithocholic (LCA), and ursodeoxycholic (UDCA) acids, respectively, were 57.4 +/- 18.6, 31.5 +/- 15.5, 8.0 +/- 9.3, 0.3 +/- 1.0, and 0.6 +/- 0.9. Values for CA were increased, whereas those for CDCA, DCA, LCA, and UDCA were decreased when compared with values in normal persons. Bile acid composition of the major bile acids did not change after 2 years on placebo medication. By contrast, in patients receiving UDCA for 2 years, bile became enriched with UDCA on average to 40.1%, and significant decreases were noted for CA (to 32.2%) and CDCA (to 19.5%). No change in percent composition was observed for DCA and LCA. Percent composition at entry and changes in composition after 2 years on UDCA were similar in patients with varying severity of PBC. In patients whose bile was not enriched in UDCA (entry and placebo-treated specimens), CA, CDCA, DCA, and the small amount of UDCA found in some of these specimens were conjugated to a greater extent with glycine (52%-64%) than with taurine (36%-48%). Treatment with UDCA caused the proportion of all endogenous bile acids conjugated with glycine to increase to 69% to 78%, while the proportion conjugated with taurine (22%-31%) fell (P <.05). Administered UDCA was also conjugated predominantly with glycine (87%).  (+info)

Fecal steroid excretion is increased in rats by oral administration of gymnemic acids contained in Gymnema sylvestre leaves. (6/334)

Gymnemic acids are the saponins with a triterpenoid structure contained in Gymnema sylvestre leaves and have the hypoglycemic effects. In spite of the cholesterol-binding properties of saponins, the effect of gymnemic acids on cholesterol metabolism has not been elucidated to date. We investigated the effects of gymnemic acids on fecal steroid excretion in rats. Three kinds of extracts from Gymnema sylvestre leaves, extract (GSE), acid precipitate (GSA) and column fractionate (GSF), of which the gymnemagenin (an aglycone of gymnemic acids) concentrations are 58.87, 161.6, and 363.3 mg/g respectively, were used for the experiments. These were administered to rats orally at the dose of 0.05-1.0 g/kg for 22 d. Rats were given free access to water and nonpurified diet without cholesterol, and the differences in fecal excretion of steroids and gymnemic acids were investigated. Although there were no significant effects of GSE, GSA and GSF decreased body weight gain and food intakes in a dose-dependent manner (P < 0.01). GSF (1.0 g/kg) significantly increased fecal excretion of neutral steroids and bile acids in a dose-dependent manner (P < 0.05), especially those of cholesterol and cholic acid (CA)-derived bile acids. The increases in fecal steroid excretion of cholesterol, total neutral steroids, total bile acids and CA-related bile acids were acute and significantly correlated with fecal gymnemagenin levels (r2 = 0.2316-0.9861, P < 0. 05). These results demonstrated for the first time that a high dose of gymnemic acids increases fecal cholesterol and CA-derived bile acid excretion. Further studies are needed to clarify the effect of gymnemic acids on cholesterol metabolism.  (+info)

Structure, evolution, and liver-specific expression of sterol 12alpha-hydroxylase P450 (CYP8B). (7/334)

The rat CYP8B cDNA encoding sterol 12alpha-hydroxylase was cloned and sequenced. The amino acid sequence of the heme-binding region of CYP8B was close to those of CYP7A (cholesterol 7alpha-hydroxylase) and CYP7B (oxysterol 7alpha-hydroxylase). Molecular phylogenetic analysis suggests that CYP8B and the CYP7 family derive from a common ancestor. The P450s of the CYP7 and CYP8 families, except for CYP8A (prostacyclin synthase), catalyze the oxygenation of sterols from an alpha surface in the middle of the steroid skeleton. These facts suggest that CYP8B is a P450 closely linked to those of the CYP7 family. CYP8B was expressed specifically in liver. Hepatic CYP8B mRNA level and the 12alpha-hydroxylase activity were altered by cholestyramine feeding, starvation, streptozotocin-induced diabetes mellitus, and administration of clofibrate, dexamethasone or thyroxin, indicating the pretranslational regulation of CYP8B expression. The enhanced CYP8B mRNA expression in streptozotocin-induced diabetic rats was significantly decreased by insulin within 3 h of its administration. These facts demonstrate a regulatory role of insulin in CYP8B expression as a suppressor.  (+info)

Gallstone formation and gallbladder mucosal changes in mice fed a lithogenic diet. (8/334)

To investigate the pathologic change of gallbladder mucosa related to gallstone formation, 52 mice were fed a lithogenic diet containing 1% cholesterol and 0.5% cholic acid and we evaluated the sequential morphologic changes in the gallbladder from two days to 40 weeks. Cholesterol gallstones began to appear after two weeks and all the mice had gallstones after eight weeks. At two days, the mitotic index was at its highest. The gallbladder mucosa showed progressive hyperplastic change with earlier papillary projection of the folds and later inward proliferation. At the same time of stone formation, mucous cells forming glands appeared. Their histochemical profile of mucin was different from that of normal epithelium. Numbers of mucous cells increased gradually until 24 weeks but slightly decreased afterward. These results suggest hyperplasia and metaplasia are closely related to the gallstone formation. Hyperplasia is probably reactive to irritating effect of lithogenic bile or stone. Metaplasia and cholesterol gallstone may develop simultaneously, and act synergistically.  (+info)

27-Hydroxycholesterol (27OH) is a strong suppressor of cholesterol synthesis and a weak activator of LXR in vitro. The regulatory importance of 27OH in vivo is controversial. Here we utilized male mice with increased levels of 27OH either due to increased production (CYP27A1 transgenic mice) or reduced metabolism (Cyp7b1-/- mice). We also used mice lacking 27OH due to a knockout of Cyp27a1. The latter mice were treated with cholic acid to compensate for reduced bile acid synthesis. The effects of the different levels of 27OH on Srebp- and other LXR-regulated genes in the liver were investigated. In the liver of CYP27tg mice we found a modest increase of the mRNA levels corresponding to the LXR target genes Cyp7b1 and Abca1. A number of other LXR-regulated genes were not affected. The effect on Abca1 mRNA was not seen in the liver of Cyp7b1-/- mice. There were little or no effects on cholesterol synthesis. In the liver of the Cyp27-/- mice treated with 0.025% cholic acid there was no significant ...

Abstract Recent studies indicate an important role for nuclear receptors in regulating lipid and carbohydrate metabolism, fibrosis and inflammation. Farnesoid X receptor (FXR) is a member of the nuclear hormone receptor superfamily. FXR is highly expressed in the liver, intestine, adrenal gland and kidney. The primary bile acids are the highest affinity endogenous ligands for FXR. The effects of FXR agonists in diabetic kidney disease, the main cause of end stage renal disease, however have not been determined. To identify the effect of FXR activation in modulation of diabetic nephropathy, we have treated 1) C57BL/6J mice on low fat diet or high fat diet with FXR agonists (GW4064 or cholic acid) for one week; 2) C57BLKS/J-db/db mice and their lean mates with GW4064 for one week; and 3) C57BL/6J-db/db mice and their lean mates with cholic acid for 12 weeks. We found that FXR agonists modulate renal SREBP-1 expression and lipid metabolism, as well as renal expression of profibrotic growth factors, ...
We report that star-shaped molecules with cholic acid cores asymmetrically grafted by low molecular weight polymers with hydrogen bonding end-groups undergo aggregation to nanofibers, which subsequently wrap into micrometer spherical aggregates with low density cores. Therein the facially amphiphilic cholic acid (CA) is functionalized by four flexible allyl glycidyl ether (AGE) side chains, which are terminated with hydrogen bonding 2-ureido-4[1H]pyrimidinone (UPy) end-groups as connected by hexyl spacers, denoted as CA(AGE6-C6H12-UPy)4. This wedge-shaped molecule is expected to allow the formation of a rich variety of solvent-dependent structures due to the complex interplay of interactions, enabled by its polar/nonpolar surface-active structure, the hydrophobicity of the CA in aqueous medium, and the possibility to control hydrogen bonding between UPy molecules by solvent selection. In DMSO, the surfactant-like CA(AGE6-C6H12-UPy)4 self-assembles into nanometer scale micelles, as expected due ...
Bile acid in the stomach plays a key role in the digestion of food in the small intestine. Two chief bile acids produced in the body include chenodeoxycholic acid and cholic acid. These acids assist in the creation of micelles, which aids in breaking down dietary fat, and is integral for the digestion of fat in the small intestine. Bile acid is a fluid secreted by the hepatocytes that flows into the canaliculi. From the canaliculi, it reaches the bile ducts, and is then transferred to the gall bladder where it is concentrated with time and the addition of other bodily fluids. Bile acids are derived from the cholesterol inside of the hepatocytem, and are made up of hydrophilic or polar faces and lipid or hydrophobic faces. Cholesterol gets converted into chenodeoxycholic and cholic acids, which are two forms of bile acid. These are combined with amino acids and released into the canaliculi. This combined nature of bile acids enables them to perform two of the most important functions in the ...

The designing, synthesizing and screening of one-bead-one-compound (OBOC) combinatorial chemistry libraries against a single target ligand has been well developed. Recently, novel cholesterol/peptide hybrid combinatorial One-Bead-One-Compound (OBOC) combinatorial libraries have been developed and synthesized with self folding capabilities. The library design strategy was based on a similar pentamer and hexamer self-folding branched tricylic libraries previously developed. The cholic acid on the side chain of the carboxyl lysine is believed to interact with fixed hydrophobic amino acids at the amino-termini (position 5) of the twin branched L-amino acid arms and self-fold into a tricyclic molecule. The newly synthesized library has arginine (R) and Lysine (K) down-proportioned to 10 % for each position to decrease the probability of positive charge nonspecific binding.

Bile acid synthesis, determined by conversion of [4-14C]cholesterol into bile acids in rat and human hepatocytes and by measurement of mass production of bile acids in rat hepatocytes, was dose-dependently decreased by cyclosporin A, with 52% (rat) and 45% (human) inhibition of 10 microM. The decreased bile acid production in rat hepatocytes was due only to a fall in the synthesis of beta-muricholic and chenodeoxycholic acids (-64% at 10 microM-cyclosporin A), with no change in the formation of cholic acid. In isolated rat liver mitochondria, 26-hydroxylation of cholesterol was potently inhibited by the drug (concn. giving half-maximal inhibition = 4 microM). These results suggest that cyclosporin A blocks the alternative pathway in bile acid synthesis, which leads preferentially to the formation of chenodeoxycholic acid. ...
While screening bile acid derivatives to find a suitable TGR5 agonist, Pellicciari and his colleagues discovered the importance of two alkyl moieties on the steroid scaffold. They also noted that the bile acid cholic acid can reverse diabetes in obese mice at extremely high doses. By incorporating the pair of slight alkyl modifications into cholic acids side chain and b ring, they developed a potent drug candidate, INT-777, which is entering clinical trials as a treatment for diabetes. It was developed in collaboration with Johan Auwerx and his team at the Swiss Federal Institute of Technology, Lausanne (J. Med. Chem. 2009, 52, 7958).. ...
1. The effects of phenobarbitone on cholesterol and bile acid metabolism have been examined in healthy humans.. 2. In three of four subjects the faecal excretion of bile acids was increased by phenobarbitone. This was associated with an increased pool size and turnover of cholic acid. Cholesterol excretion was not clearly affected. The fourth subject who did not respond was also exceptional in not showing an increase in the plasma clearance of antipyrine.. 3. The three responsive subjects also developed significant increases in plasma cholesterol and triglyceride concentrations. These findings were associated with an early rise in very-low-density lipoprotein and a fall in plasma cholesterol specific radioactivity in one patient, changes compatible with increased cholesterol synthesis. ...
A study of the structural requirements of cholic acid derivatives as liver X receptor (LXR) ligands was performed. A model of cholenamide derivative 1 complexed with LXR showed that the C24 carbonyl oxygen forms a hydrogen bond with His435 located close to Trp457. The N,N-dimethyl group is located in a hydrophobic pocket. Based on these data, we designed compounds with high affinity for LXRs. Cholenamide derivatives 1-11 were synthesized from 3β-acetyl-Δ5-cholenic acid 20, and lactams 12-19 were synthesized from alcohol 25. Tertiary amides 3 and 4 showed higher activity in reporter assays, and compounds with hydrophobic residues exhibited the highest activity of all derivatives. The stereochemistry at C23 was found to be an important determinant of EC50 and gene transactivation, as each isomer exhibited different activity ...
TY - JOUR. T1 - Bile acids lower triglyceride levels via a pathway involving FXR, SHP, and SREBP-1c. AU - Watanabe, Mitsuhiro. AU - Houten, Sander M.. AU - Wang, Li. AU - Moschetta, Antonio. AU - Mangelsdorf, David J.. AU - Heyman, Richard A.. AU - Moore, David D.. AU - Auwerx, Johan. PY - 2004/1/1. Y1 - 2004/1/1. N2 - 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 hypertriglyceridemia. At the molecular level, CA decreases hepatic expression of SREBP-1c and its lipogenic target genes. Through the use of mouse mutants for the short heterodimer partner (SHP) and liver X receptor (LXR) α and β, we demonstrate the critical dependence of the reduction of SREBP-1c expression by either natural or synthetic farnesoid X receptor (FXR) agonists on both SHP and LXRα and LXRβ. These results suggest that ...

1. The duodenal bile acid composition was analysed in 24 control subjects and 107 patients with various types of hyperlipoproteinaemia. A highly significant negative correlation was observed between the proportions of deoxycholic acid and cholic acid as well as between deoxycholic acid and chenodeoxycholic acid. Patients with gall-bladder disease had an increased proportion of deoxycholic acid in their bile.. 2. Eight control subjects were studied before and during the ingestion of 1·9 mmol (0·75 g) of deoxycholic acid daily. In these subjects a rise in the proportion of deoxycholic acid was also accompanied by a fall in the proportion of both cholic acid and chenodeoxycholic acid in duodenal bile.. 3. The biliary lipid composition and cholesterol saturation was determined before and during the administration of 1·9 mmol (0·75 g) of chenodeoxycholic acid (n = 12) or deoxycholic acid (n = 8) daily for 3-4 weeks. The cholesterol saturation was decreased during the chenodeoxycholic acid ...
Chenodeoxycholoyl-CoA is bile acid Coenzyme A ester. In humans, bile acids conjugated with glycine and taurine are the major solutes in bile, and unconjugated bile acids are almost nondetectable in normal bile. Conjugated bile acids are less toxic and are more efficient promoters of intestinal absorption of dietary lipid than unconjugated bile acids. The synthesis of bile acid and amino acid conjugates in human liver is the result of two independent enzymatic reactions with a bile acid coenzyme A thioester intermediate formation of bile acid-CoA esters, considered the rate-limiting step in bile acid amidation and catalyzed by an ATP-dependent microsomal enzyme, bile acid-CoA synthetase (EC In the second reaction, the thioester bond is cleaved, and an amide bond is formed between the bile acid and the amino acids glycine or taurine. The bile acid-CoA:amino acid N-acyltransferase (EC catalyzes this reaction in the cytosol prior to secretion into bile. In human liver the ...

Phospholipids and bile acids, by virtue of their amphiphilic properties, can interact in nonpolar media forming inverted structures (micelles) which presumably have an hydrophilic core and might act as diffusional carriers (ionophores) of electrolytes across low dielectric constant media or lipid membranes.. The Na+ ionophoretic capability of various purified phospholipids and the modulating effects of bile acids and phospatidylcholine was examined by: (a) measurement of 22Na+ partition into the organic phase (chloroform) of a two-phase system and (b) direct measurement of the translocation of 22Na+ across a bulk chloroform phase separating two aqueous phases in a Pressman cell. All phospholipids tested, except for phosphatidylcholine, showed ionophoretic capability for Na+ at micromolar concentrations. Cardiolipin and phosphatidylserine were the most efficient Na+ carriers, comparable with monensin, an established Na+ ionophore. In contrast, cholic acid as well as other bile acids ...
CYP7A1 encodes the rate limiting enzyme for the conversion of cholesterol to bile acids. Several studies have demonstrated that elevated expression of CYP7A1 confers protection from hypercholesterolemia. CYP7A1 expression is regulated by two nuclear receptors, farnesoid X receptor (FXR) and small heterodimer (SHP). Here we demonstrate that although FXR−/ − and SHP−/ − mice have similarly elevated levels of CYP7A1, FXR−/ − mice have elevated serum cholesterol and triglyceride levels and serum markers of hepatic inflammation whereas the SHP−/ − mice do not. This suggestion of a beneficial lipid effect of the loss of SHP was confirmed in a cholesterol/cholic acid diet model, in which SHP−/ − mice were strongly protected form diet-induced hypercholesterolemia and hepatic inflammation. To examine the effects of the loss of SHP in a model relevant to human dyslipidemia, we generated LDLR−/ −SHP−/ − mice. The LDLR−/ −SHP−/ − mice were highly resistant to Western ...
The classical functions of bile acids include acting as detergents to facilitate the digestion and absorption of nutrients in the gut. In addition, bile acids also act as signaling molecules to regulate glucose homeostasis, lipid metabolism and energy expenditure. The signaling potential of bile acids in compartments such as the systemic circulation is regulated in part by an efficient enterohepatic circulation that functions to conserve and channel the pool of bile acids within the intestinal and hepatobiliary compartments. Changes in hepatobiliary and intestinal bile acid transport can alter the composition, size, and distribution of the bile acid pool. These alterations in turn can have significant effects on bile acid signaling and their downstream metabolic targets. This review discusses recent advances in our understanding of the inter-relationship between the enterohepatic cycling of bile acids and the metabolic consequences of signaling via bile acid-activated receptors, such as ...

Serum total bile acids should be performed in preference. VCGS does not perform serum total bile acids testing.. ...
It is widely accepted that hyperlipidemia may lead to atherosclerosis, and hyperlipidemia has been identified as an independent risk factor for coronary heart disease and ischemic stroke [14]. Extensive epidemiologic and experimental studies have supported the conception that hyperlipidemia may cause nervous system-related diseases [15, 16]. We evaluated the hyperlipidemia model with reference to the Deepa modeling method (normal rat chow supplemented with 4% cholesterol, 1% cholic acid and 0.5% thiouracil, also called the CCT diet) [9]. In rats that were fed the CCT diet for 1 week, the levels of serum TC, TG and LDL-C increased by 2.40, 1.29 and 1.75 times,(P , 0.05), respectively, and the levels of serum HDL-C decreased by 0.26 times (P , 0.05). Factorial analysis shows that the severity of hyperlipidemia was aggravated with the extension of the CCT diet.. Brain tissue is composed of neurons and glial cells, and this tissue is a significant integration center for body movements, sensations ...

Dec 22, 2005. SAN DIEGO, CA - Dec 22, 2005 - Diazyme Laboratories, a company that applies its proprietary enzyme technologies to develop low cost and high quality diagnostic products for clinical and research uses, announced today that the U.S. Food and Drug Administration (FDA) has granted Diazyme 510(K) clearance to market its Enzymatic Total Bile Acids (TBA) Assay Kit for the quantitative determination of total bile acids in human blood samples.. Total bile acids is a well known bio-marker for diagnosis of liver diseases. Serum total bile acids are elevated in patients with acute hepatitis, chronic hepatitis, liver sclerosis, and liver cancer. Total bile acids levels are found to be the most sensitive indicator for monitoring the effectiveness of interferon treatment of chronic hepatitis C patients. Moreover, total bile acids tests are also widely used to screen pregnant women for the condition of obstetric cholestasis, a disease that is caused by elevated total bile acids in the bloodstream ...

Acyl-CoA synthetase involved in bile acid metabolism. Proposed to catalyze the first step in the conjugation of C24 bile acids (choloneates) to glycine and taurine before excretion into bile canaliculi by activating them to their CoA thioesters. Seems to activate secondary bile acids entering the liver from the enterohepatic circulation. In vitro, also activates 3-alpha,7-alpha,12-alpha-trihydroxy-5-beta-cholestanate (THCA), the C27 precursor of cholic acid deriving from the de novo synthesis from cholesterol.
In addition to their well-known function as dietary lipid detergents, bile acids have emerged as important signalling molecules that regulate energy homeostasis. Recent studies have highlighted that disrupted bile acid metabolism is associated with metabolism disorders such as dyslipidaemia, intestinal chronic inflammatory diseases and obesity. In particular, type 2 diabetes (T2D) is associated with quantitative and qualitative modifications in bile acid metabolism. Bile acids bind and modulate the activity of transmembrane and nuclear receptors (NR). Among these receptors, the G-protein-coupled bile acid receptor 1 (TGR5) and the NR farnesoid X receptor (FXR) are implicated in the regulation of bile acid, lipid, glucose and energy homeostasis. The role of these receptors in the intestine... in energy metabolism regulation has been recently highlighted. More precisely, recent studies have shown that FXR is important for glucose homeostasis in particular in metabolic disorders such as T2D and ...
The serum concentration of TBA in healthy neonates significantly exceeds that in children over 1 year of age, a condition called physiological cholestasis.9 The urinary TBA:creatinine ratio was raised in the first week after birth, then decreased gradually. The high concentration of TBA in urine may be attributable to either an enhanced stimulation of the enterohepatic circulation of bile acids or an impaired hepatic clearance or excretion.10The highest value for TBA in meconium was in neonates. This value is greatly influenced by events or conditions during pregnancy, such as the presence of biliary bile in the fetal duodenum or the ingestion of amniotic fluid by the fetus.10 11 Ketonic bile acids are usually considered to result from the bacterial oxidation of primary bile acids.12 In this study we detected ketonic bile acids early in life. The intestine may be colonised by bacterial flora during the first week.13 A high concentration of 3-oxo Δ4 bile acids in serum or urine has been ...
FXR is expressed at high levels in the liver and intestine. Chenodeoxycholic acid and other bile acids are natural ligands for FXR. Similar to other nuclear receptors, when activated, FXR translocates to the cell nucleus, forms a dimer (in this case a heterodimer with RXR) and binds to hormone response elements on DNA, which up- or down-regulates the expression of certain genes.[6] One of the primary functions of FXR activation is the suppression of cholesterol 7 alpha-hydroxylase (CYP7A1), the rate-limiting enzyme in bile acid synthesis from cholesterol. FXR does not directly bind to the CYP7A1 promoter. Rather, FXR induces expression of small heterodimer partner (SHP), which then functions to inhibit transcription of the CYP7A1 gene. In this way, a negative feedback pathway is established in which synthesis of bile acids is inhibited when cellular levels are already high. FXR has also been found to be important in regulation of hepatic triglyceride levels.[7] Studies have also shown the FXR to ...
Bile acids are best known as detergents involved in the digestion of lipids. In addition, new data in the last decade have shown that bile acids also function as gut hormones capable of influencing metabolic processes via receptors such as FXR (farnesoid X receptor) and TGR5 (Takeda G protein-coupled receptor 5). These effects of bile acids are not restricted to the gastrointestinal tract, but can affect different tissues throughout the organism. It is still unclear whether these effects also involve signaling of bile acids to the central nervous system (CNS). Bile acid signaling to the CNS encompasses both direct and indirect pathways. Bile acids can act directly in the brain via central FXR and TGR5 signaling. In addition, there are two indirect pathways that involve intermediate agents released upon interaction with bile acids receptors in the gut. Activation of intestinal FXR and TGR5 receptors can result in the release of fibroblast growth factor 19 (FGF19) and glucagon-like peptide 1 (GLP-1), both
The diethanolamine salt of the mono (α,p-dimethylbenzyl) ester of d-camphoric acid (Gallogen) augmented diet-induced hypercholesterolemia and hyperlipemia in the rat, while depressing liver cholesterol and total lipid concentrations. Diethanolamine had virtually identical effects. Gallogen, given orally to rats with biliary fistulas had a slight hydrocholeretic effect, but did not influence biliary excretion of cholesterol, cholic acid, or chenodeoxycholic acid.. ...
By Alexander J. Varond & Josephine M. Torrente -. On March 17, 2015 FDA approved Cholbam (cholic acid) for pediatric and adult patients with bile acid synthesis disorders due to single enzyme defects, and for patients with peroxisomal disorders. In approving Cholbam, FDA also issued the third rare pediatric disease priority review voucher (Pediatric Voucher), triggering the Pediatric Voucher programs 1-year sunset clause in Section 529(b)(5) of the FD&C Act. Recall that a Pediatric Voucher is a voucher issued to the sponsor of a rare pediatric disease product application that entitles the holder of such voucher to priority review (instead of a longer standard review) of a single NDA or BLA after the date of approval of the rare pediatric disease product application. A qualifying rare pediatric disease product application is an NDA or BLA for a drug or biologic intended to prevent or treat a rare pediatric disease. Such drug or biologic may not contain any active ingredient (including any ...
The limited success of life-style modifications like diet and exercise in controlling weight is apparent in the ever-expanding epidemic of obesity. An alternative approach might be to manipulate metabolic rate. For instance, thyroid hormone increases basal metabolism and stimulates weight loss; however, excess thyroid hormone can lead to dangerous systemic effects, such as atrial fibrillation and bone loss (see Baxter and Webb). Watanabe et al. found that supplementing a high-fat diet (HF) with the bile acid cholic acid (CA) limited weight gain in C57BL/6J mice. Indeed, obese mice fed HF supplemented with CA lost weight and adipose mass. Mice fed HF supplemented with CA showed increased oxygen consumption and CO2 production relative to mice fed chow or HF without CA, indicating increased energy expenditure. Expression of the gene that encodes the adenosine 3′,5′-monophosphate (cAMP)-dependent thyroid hormone activating enzyme type 2 iodothyronine deiodinase (D2, which converts thyroxine into ...
Ten inbred strains of mice were fed an atherogenic diet containing 1.25% cholesterol, 0.5% cholic acid and 15% fat. The strains were examined for plasma cholesterol and triglyceride levels and for formation of lipid-containing lesions in the aortic wall. The strains differed considerably in the frequency of lesion formation after 14 weeks on the atherogenic diet with a range of 0-1.8 lesions/mouse. The order of susceptibility to lesion formation from the least susceptible to the most susceptible was BALB/cJ, C3H/J, A/J, SWR/J, NZB/J, less than 129/J, AKR/J, DBA/2J, less than C57L/J less than C57BL/6J. Total plasma cholesterol after 5 weeks on the diet varied from 131 mg/dl to 328 mg/dl among strains; however, there was little correlation between total cholesterol levels and susceptibility to lesion formation (r = 0.29). Plasma triglycerides after 5 weeks on the diet varied less than cholesterol with a range of 137-220 mg/dl. An analysis of the genetic differences among inbred strains of mice

Analogs of the cyclic nucleotides cAMP and cGMP have been extensively used to mimic or modulate cellular events mediated by protein kinase A (PKA), Exchange protein directly activated by cAMP (Epac), or protein kinase G (PKG). We report here that some of the most commonly used cyclic nucleotide analogs inhibit transmembrane transport mediated by the liver specific organic anion transporter peptides OATP1B1 and OATP1B3, unrelated to actions on Epac, PKA or PKG. Several cAMP analogs, particularly with 8-pCPT-substitution, inhibited nodularin (Nod) induced primary rat hepatocyte apoptosis. Inhibition was not mediated by PKA or Epac, since increased endogenous cAMP, and some strong PKA- or Epacactivating analogs failed to protect cells against Nod induced apoptosis. The cAMP analogs inhibiting Nod induced hepatocyte apoptosis also reduced accumulation of radiolabeled Nod or cholic acid in primary rat hepatocytes. They also inhibited Nod induced apoptosis in HEK293 cells with enforced expression of ...
