Sterol 27-Hydroxylase Deficiency as a Cause of Neonatal Cholestasis: Report of 2 Cases and Review of the Literature

Frontiers in Pediatrics, 2021
Introduction: Inborn errors of primary bile acid (BA) synthesis are rare autosomal recessive disorders responsible for 1–2% of cases of neonatal cholestasis.

Bile acid metabolism and sleep: Mechanistic interplay and clinical implications of the gut–liver–brain axis

Sleep Research, EarlyView.
Abstract The bidirectional interplay between sleep and metabolic homeostasis is fundamental to physiological health. While the roles of glucose and lipid metabolism in sleep regulation have been extensively characterized, bile acids (BAs), which are traditionally viewed as digestive surfactants, are emerging as critical metabolic messengers with ...

Effects of Common Food Additives Kappa‐, Iota‐ and Lambda‐Carrageenans on Intestinal Epithelial Cell Activation and Barrier Disruption

Clinical &Experimental Allergy, EarlyView.
Carrageenans, widely used food additives, disrupted intestinal epithelial integrity in a gut‐on‐a‐chip model. All types (κ‐, ɩ‐, λ‐) induced cytotoxicity, inflammation and tight junction (TJ) disruption, triggering TNF‐mediated immune responses. λ‐Carrageenan had the most severe effects, supporting the Epithelial Barrier Theory linking food additives ...

Inhibition of Marek’s Disease Virus Replication and Spread by 25-hydroxycholesterol and 27-hydroxycholesterol In Vitro

Viruses, 2023
Marek’s disease virus (MDV) causes a deadly lymphoproliferative disease in chickens, resulting in huge economic losses in the poultry industry. It has been suggested that MDV suppresses the induction of type I interferons and thus escapes immune control.

Disruption of Vitamin D and Calcium Signaling in Keratinocytes Predisposes to Skin Cancer. [PDF]

, 2016
1,25 dihydroxyvitamin D (1,25(OH)2D), the active metabolite of vitamin D, and calcium regulate epidermal differentiation. 1,25(OH)2D exerts its effects through the vitamin D receptor (VDR), a transcription factor in the nuclear hormone receptor family ...

Hepatic caveolin‐1 is enhanced in Cyp27a1/ApoE double knockout mice

FEBS Open Bio, 2016
Sterol 27‐hydroxylase (CYP27A1) is involved in bile acid synthesis and cholesterol homoeostasis. Cyp27a1(−/−)/Apolipoprotein E(−/−) double knockout mice (DKO) fed a western diet failed to develop atherosclerosis. Caveolin‐1 (CAV‐1), the main component of caveolae, is associated with lipid homoeostasis and has regulatory roles in vascular diseases.

Unveiling Hepatic Protein Alterations in Neonatal and Infant Biliary Atresia

Clinical Pharmacology &Therapeutics, Volume 119, Issue 6, Page 1584-1596, June 2026.
Pediatric populations differ from adults in drug elimination capacity. While current scaling methods account for enzyme and transporter maturation, they overlook comorbidities, such as biliary atresia (BA), a liver disease appearing within the first 2–8 weeks of life that can progress to cirrhosis.

Circulating 27-hydroxycholesterol and breast cancer tissue expression of CYP27A1, CYP7B1, LXR-β, and ERβ: results from the EPIC-Heidelberg cohort

Breast Cancer Research, 2020
Background Experimental and epidemiological studies demonstrate a role for 27-hydroxycholesterol (27HC) in breast cancer development, though results are conflicting. Cholesterol 27-hydroxylase (CYP27A1) and oxysterol 7-alpha-hydroxylase (CYP7B1) regulate

27-hydroxycholesterol and DNA damage repair: implication in prostate cancer

Frontiers in Oncology, 2023
IntroductionWe previously reported that cholesterol homeostasis in prostate cancer (PC) is regulated by 27-hydroxycholesterol (27HC) and that CYP27A1, the enzyme that converts cholesterol to 27HC, is frequently lost in PCs. We observed that restoring the

Gender Differences in Bile Acids and Microbiota in Relationship with Gender Dissimilarity in Steatosis Induced by Diet and FXR Inactivation. [PDF]

, 2017
This study aims to uncover how specific bacteria and bile acids (BAs) contribute to steatosis induced by diet and farnesoid X receptor (FXR) deficiency in both genders.
