Vitamin A Metabolism by Dendritic Cells Triggers an Antimicrobial Response against Mycobacterium tuberculosis. [PDF]

, 2019
Epidemiological evidence correlates low serum vitamin A (retinol) levels with increased susceptibility to active tuberculosis (TB); however, retinol is biologically inactive and must be converted into its bioactive form, all-trans retinoic acid (ATRA ...

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 ...

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.

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

The Genetic Landscape of Hereditary Spastic Paraplegia in Greece

Clinical Genetics, EarlyView.
We investigated 112 Greek index‐cases with hereditary spastic paraplegia collected over > 25 years using NGS and MLPA. We identified a causative variant in 68 patients (60.7%), including 7 novel causative variants. This study presents a comprehensive overview of the phenotypic and genotypic spectrum of HSP in the Greek population.

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.

A Lung‐Immune Dual‐Humanized Mouse Using Cryopreserved Tissue Enables Infection and Immune Profiling of Human Common Cold Coronaviruses

Advanced Science, Volume 13, Issue 16, 18 March 2026.
Cryopreserved lung‐humanized mice overcome the dependency to fresh tissues and permit head‐to‐head profiling of all four human common cold coronaviruses versus SARS‐CoV‐2 infection; the model validates Paxlovid efficacy against HKU1 and, when coupled with human immune‐system engraftment, enables interrogation of lung‐resident human immunity and HKU1 ...

Effect of Cyp27A1 gene dosage on atherosclerosis development in ApoE‐knockout mice

The FASEB Journal, 2013
In humans, sterol 27‐hydroxylase (CYP27A1) deficiency leads to cholesterol deposition in tendons and vasculature. Thus, in addition to its role in bile acid synthesis, where it converts cholesterol to 27‐hydroxycholesterol (27‐OHC), CYP27A1 may also be atheroprotective. Cyp27A1‐deficient ( Cyp27A1
