Bile Acid Diarrhea: Prevalence, Pathogenesis, and Therapy

Gut and Liver, 2015
Bile acid diarrhea (BAD) is usually seen in patients with ileal Crohn’s disease or ileal resection. However, 25% to 50% of patients with functional diarrhea or diarrhea-predominant irritable bowel syndrome (IBS-D) also have evidence of BAD.

ROS/pH‐Responsive Phenylboronic Acid–Chitosan Nanoparticles Improve Silymarin‐Mediated Hepatoprotection After Hepatectomy With Gut‐Liver Axis‐Associated Responses

Advanced Science, EarlyView.
Bioactive phenylboronic acid–chitosan nanoparticles enable responsive silymarin delivery for post‐hepatectomy liver protection. The nanoplatform integrates antioxidant and antibacterial functions, improves hepatic recovery, and is associated with coordinated shifts in gut microbiota, metabolites, cytokines, and hepatic proteomic pathways, suggesting a ...

Prox1-mediated recruitment of LSD1/NuRD complex to CYP7A1 promoter participates in bile acids induced repression of CYP7A1.

, 2013
(A) Chenodeoxycholic acid (CDCA) treatment of HepG2 cells results in repression of CYP7A1 transcription. Total RNA from HepG2 cells treated with 25 µmol/L CDCA or DMSO vehicle for 16 hours was subjected to quantitative real-time PCR analysis of CYP7A1 ...

Genotype–Phenotype Correlations of Monoallelic PFIC Variants in Pediatric Liver Disease: A Multicenter Retrospective Cohort Study

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Progressive familial intrahepatic cholestasis (PFIC) is classically caused by biallelic pathogenic variants, yet monoallelic variants of uncertain significance (VUS) in PFIC‐associated genes are increasingly identified in children with cholestasis, creating diagnostic uncertainty.

Glucose stimulates cholesterol 7α-hydroxylase gene transcription in human hepatocytes[S]

Journal of Lipid Research, 2010
Bile acids play important roles in the regulation of lipid, glucose, and energy homeostasis. Recent studies suggest that glucose regulates gene transcription in the liver.

Pathophysiological Mechanisms of Emaciation Syndrome in Plectropomus leopardus: Insights From Histology and Transcriptomics

Animal Research and One Health, EarlyView.
Integrated phenotypic, histological, transcriptomic, and validation analyses reveal that emaciation syndrome in Plectropomus leopardus is associated with intestinal structural damage, hepatic metabolic remodeling, and muscle protein degradation, highlighting coordinated multi‐tissue alterations underlying disease progression.

Integrated assessment of rifampicin‐mediated induction of transporters and drug‐metabolizing enzymes in a long‐term human liver tissue chip system

Clinical Pharmacology &Therapeutics, EarlyView.
Rifampicin is a prototypical clinical inducer used in drug–drug interaction (DDI) studies. However, the clinical relevance and predictability of rifampicin‐mediated hepatic transporter induction remain poorly defined. Conventional hepatocyte culture models fail to capture clinically relevant regulation of transporters and drug‐metabolizing enzymes ...

Transgenic expression of CYP7A1 in LDL receptor-deficient mice blocks diet-induced hypercholesterolemia

Journal of Lipid Research, 2006
Constitutive expression of a cholesterol-7α-hydroxylase (CYP7A1) transgene in LDL receptor-deficient mice blocked the ability of a cholesterol-enriched diet to increase plasma levels of apolipoprotein B-containing lipoproteins.

Cholesterol 7α-hydroxylase protects the liver from inflammation and fibrosis by maintaining cholesterol homeostasis[S]

Journal of Lipid Research, 2016
Cholesterol 7α-hydroxylase (CYP7A1) plays a critical role in control of bile acid and cholesterol homeostasis. Bile acids activate farnesoid X receptor (FXR) and Takeda G protein-coupled receptor 5 (TGR5) to regulate lipid, glucose, and energy metabolism.

Normal cholestanol in a genetically confirmed cerebrotendious xanthomatosis case presenting as neonatal jaundice

JPGN Reports, EarlyView.
Abstract Cerebrotendinous xanthomatosis (CTX) is a treatable genetic disorder associated with deficiency of the sterol 27‐hydroxylase enzyme (CYP27A1), important in bile acid synthesis. CTX may present in the newborn period as hepatic jaundice/cholestasis, that can resolve or can progress to fatal liver disease.
