Hyocholic acid is a primary bile acid in pigs and other mammals. [1] It has also been found in urine samples from patients with cholestasis. [2] Hyocholic acid is converted by gut microflora primarily to taurohyocholate and, to a lesser extent, taurocholic acid and tauro-β-muricholic acid in mice.[3] Hyocholic acid has low toxicity against human hepatoma HepG2 cells.[3][4]

Hyocholic Acid species improve glucose homeostasis through a distinct TGR5 and FXR signaling mechanism
Cell Metab 2021 Apr 6;33(4):791-803.e7.PMID:33338411DOI:10.1016/j.cmet.2020.11.017.
Hyocholic Acid (HCA) and its derivatives are found in trace amounts in human blood but constitute approximately 76% of the bile acid (BA) pool in pigs, a species known for its exceptional resistance to type 2 diabetes. Here, we show that BA depletion in pigs suppressed secretion of glucagon-like peptide-1 (GLP-1) and increased blood glucose levels. HCA administration in diabetic mouse models improved serum fasting GLP-1 secretion and glucose homeostasis to a greater extent than tauroursodeoxycholic acid. HCA upregulated GLP-1 production and secretion in enteroendocrine cells via simultaneously activating G-protein-coupled BA receptor, TGR5, and inhibiting farnesoid X receptor (FXR), a unique mechanism that is not found in other BA species. We verified the findings in TGR5 knockout, intestinal FXR activation, and GLP-1 receptor inhibition mouse models. Finally, we confirmed in a clinical cohort, that lower serum concentrations of HCA species were associated with diabetes and closely related to glycemic markers.
Hyocholic Acid species as novel biomarkers for metabolic disorders
Nat Commun 2021 Mar 5;12(1):1487.PMID:33674561DOI:10.1038/s41467-021-21744-w.
Hyocholic Acid (HCA) is a major bile acid (BA) species in the BA pool of pigs, a species known for its exceptional resistance to spontaneous development of diabetic phenotypes. HCA and its derivatives are also present in human blood and urine. We investigate whether human HCA profiles can predict the development of metabolic disorders. We find in the first cohort (n = 1107) that both obesity and diabetes are associated with lower serum concentrations of HCA species. A separate cohort study (n = 91) validates this finding and further reveals that individuals with pre-diabetes are associated with lower levels of HCA species in feces. Serum HCA levels increase in the patients after gastric bypass surgery (n = 38) and can predict the remission of diabetes two years after surgery. The results are replicated in two independent, prospective cohorts (n = 132 and n = 207), where serum HCA species are found to be strong predictors for metabolic disorders in 5 and 10 years, respectively. These findings underscore the association of HCA species with diabetes, and demonstrate the feasibility of using HCA profiles to assess the future risk of developing metabolic abnormalities.
Decreased Hyocholic Acid and Lysophosphatidylcholine Induce Elevated Blood Glucose in a Transgenic Porcine Model of Metabolic Disease
Metabolites 2022 Nov 23;12(12):1164.PMID:36557202DOI:10.3390/metabo12121164.
(1) Background: This work aims to investigate the metabolomic changes in PIGinH11 pigs and investigate differential compounds as potential therapeutic targets for metabolic diseases. (2) Methods: PIGinH11 pigs were established with a CRISPR/Cas9 system. PNPLA3I148M, hIAPP, and GIPRdn were knocked in the H11 locus of the pig genome. The differential metabolites between and within groups were compared at baseline and two months after high-fat-high-sucrose diet induction. (3) Results: 72.02% of the 815 detected metabolites were affected by the transgenic effect. Significantly increased metabolites included isoleucine, tyrosine, methionine, oxoglutaric acid, acylcarnitine, glucose, sphinganines, ceramides, and phosphatidylserines, while fatty acids and conjugates, phosphatidylcholines, phosphatidylethanolamines, and sphingomyelins were decreased. Lower expression of GPAT3 and higher expression of PNPLA3I148M decreased the synthesis of diacylglycerol and phosphatidylcholines. Accumulated ceramides that block Akt signaling and decrease Hyocholic Acid and lysophosphatidylcholines might be the main reason for increased blood glucose in PIGinH11 pigs, which was consistent with metabolomic changes in patients. (4) Conclusions: Through serum metabolomics and lipidomics studies, significant changes in obesity and diabetes-related biomarkers were detected in PIGinH11 pigs. Excessive fatty acids β-oxidation interfered with glucose and amino acids catabolism and reduced phosphatidylcholines. Decreased Hyocholic Acid, lysophosphatidylcholine, and increased ceramides exacerbated insulin resistance and elevated blood glucose. Phosphatidylserines were also increased, which might promote chronic inflammation by activating macrophages.
Increased glycine-amidated Hyocholic Acid correlates to improved early weight loss after sleeve gastrectomy
Surg Endosc 2018 Feb;32(2):805-812.PMID:28779240DOI:10.1007/s00464-017-5747-y.
Background: Bile acids (BAs) are post-prandial hormones that play an important role in glucose and lipid homeostasis as well as energy expenditure. Total and glycine-amidated BAs increase after sleeve gastrectomy (SG) and correlate to improved metabolic disease. No specific bile acid subtype has been shown conclusively to mediate the weight loss effect. Therefore, the objective of this study was to prospectively evaluate the comprehensive changes in meal-stimulated BAs after SG and determine if a specific change in the BA profile correlates to the early weight loss response. Methods: Patients were prospectively enrolled at the University of Nebraska Medical Center who were undergoing a SG for treatment of morbid obesity. Primary and secondary plasma bile acids and their amidated (glycine, G-, or taurine, T-) subtypes were measured at fasting, 30 and 60 min after a liquid meal performed pre-op, and at 6 and 12 weeks post-op. Area under the curve (AUC) was calculated for the hour meal test for each bile acid subtype. BAs that were significantly increased post-op were correlated to body mass index (BMI) loss. Results: Total BA AUC was significantly increased at 6 (p < 0.01) and 12 weeks post-op (p < 0.01) compared to pre-operative values. The increase in total BA AUC was due to a statistically significant increase in G-BAs. Nine different BA AUC subtypes were significantly increased at both 6 and 12 weeks post-op. Increased total and G-chenodeoxycholic acid AUC was significantly correlated to the 6 week BMI loss (p = 0.03). Increased G-hyocholic acid was significantly correlated to increased weight loss at both 6 (p = 0.05) and 12 weeks (p = 0.006). Conclusions: SG induced an early and persistent post-prandial surge in multiple bile acid subtypes. Increased G-hyocholic consistently correlated with greater early BMI loss. This study provides evidence for a role of BAs in the surgical weight loss response after SG.
Effect of Hyocholic Acid on the prevention and dissolution of biliary cholesterol crystals in mice
Can J Physiol Pharmacol 1988 Aug;66(8):1028-34.PMID:3179836DOI:10.1139/y88-168.
Gallstone prevention and dissolution were studied in a mouse model of cholesterol cholelithiasis using Hyocholic Acid (3 alpha, 6 alpha, 7 alpha-trihydroxy-5 beta-cholanic acid). Addition of Hyocholic Acid, 0.1 or 0.3%, in the lithogenic diet (1% cholesterol + 0.5% cholic acid) prevented the formation of cholesterol monohydrate crystals in 70 and 90% of cases, respectively. On the other hand, chow diet supplemented with 0.1 or 0.3% Hyocholic Acid dissolved cholesterol crystals in lithiasic mice in, respectively, 80 and 100% of cases within 12 days. In both protocols, biles were largely supersaturated with cholesterol; lecithin-cholesterol lamellar liquid crystals were responsible for the transport of the excess cholesterol content. The percentage of hydrophilic bile salts (Hyocholic Acid, hyodeoxycholic acid, beta-muricholic acid) in bile, although moderate (15-50% of total bile salts), appears to induce such liquid crystalline dispersion. This study demonstrates that the balance between hydrophilic and hydrophobic bile salts plays a major role in the prevention and dissolution of cholesterol crystals. It is also shown that the desaturation of biliary cholesterol is not a prerequisite for gallstone dissolution.
