Dynamics of Kidney Calcium and Phosphorus Mineral Handling in Laying Hens During the Transition to Egg Production

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT The transition from immature pullets to sexually mature female chickens is accompanied by pronounced structural and functional modifications. This is accompanied by coordinated changes in hormonal and metabolic pathways that primarily regulate reproduction, nutrient utilization, and mineral homeostasis to compensate for temporary imbalances ...

TNFSF14/LIGHT responses in intestinal and oesophageal fibroblasts are differentially modulated by hydroxylase inhibitors

The Journal of Physiology, EarlyView.
Abstract figure legend LIGHT is a mutual mediator of intestinal and oesophageal fibroblast inflammation with common as well as tissue‐specific effects. Hydroxylase inhibitors can selectively suppress inflammatory factors in both cell types, albeit targeting different signalling pathways.

Systematic Optimization of an SLE‐DAPTAD LC–MS/MS Workflow for Simultaneous Quantification of Low‐Abundance Vitamin D3 Metabolites in Plasma

Rapid Communications in Mass Spectrometry, Volume 40, Issue 20, 30 October 2026.
ABSTRACT Rationale Liquid chromatography–tandem mass spectrometry (LC–MS/MS) analysis of vitamin D3 metabolites is analytically challenging because these compounds are structurally similar, strongly matrix‐associated, and have poor ionization efficiency.

Conversion of 7-ketocholesterol to oxysterol metabolites by recombinant CYP27A1 and retinal pigment epithelial cells[S]

Journal of Lipid Research, 2011
Of the different oxygenated cholesterol metabolites, 7-ketocholesterol (7KCh) is considered a noxious oxy­sterol implicated in the development of certain pathologies, including those found in the eye.

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

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.

A Multifaceted Interplay Among Hemophagocytosis, Interleukin‐18, and Type I Interferon Distinguishes Still Disease From Other Autoinflammatory Diseases

Arthritis &Rheumatology, Volume 78, Issue 9, Page 1961-1974, September 2026.
Objective The unknown pathophysiology and the lack of specific features for systemic juvenile idiopathic arthritis and adult‐onset Still disease (collectively known as Still disease; SD) delay diagnosis and appropriate treatment. The goal of this study was to identify features and mechanisms that distinguish SD from other systemic autoinflammatory ...

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

Synthetic Food Colorants and Gut Microbiota: A Systematic Review of Preclinical Studies

Food Frontiers, Volume 7, Issue 5, September 2026.
ABSTRACT Growing evidence suggests that industrial food processing, including the excess consumption of food additives, might have a negative impact on human health. Despite regulatory safety evaluations, their impact on gut microbiota remains poorly characterized.

c.1263+1G>A Is a Latent Hotspot for CYP27A1 Mutations in Chinese Patients With Cerebrotendinous Xanthomatosis

Frontiers in Genetics, 2020
BackgroundCerebrotendinous xanthomatosis (CTX) is an autosomal recessive disorder of bile acid synthesis caused by mutations in the CYP27A1 gene. CTX is an underdiagnosed and potentially treatable disease, thus a detailed appreciation of the phenotypic ...
