On the regulatory role of side-chain hydroxylated oxysterols in the brain. Lessons from CYP27A1 transgenic and Cyp27a1−/− mice1 [PDF]

Journal of Lipid Research, 2013
The two oxysterols, 27-hydroxycholesterol (27OH) and 24S-hydroxycholesterol (24OH), are both inhibitors of cholesterol synthesis and activators of the liver X receptor (LXR) in vitro.

Tissue specific role of ABCA1 in lung cholesterol homeostasis under high-cholesterol diet [PDF]

Frontiers in Nutrition
BackgroundATP-binding cassette subfamily A1 (ABCA1) and sterol 27-hydroxylase (CYP27A1) are essential regulators of cholesterol metabolism. However, their tissue-specific roles, particularly in the lung, under high-cholesterol diet (HCD) conditions ...

Integrative multi-omics and machine learning reveals the spatial niche distribution and role of CYP27A1+TAMs in immunotherapy response in non-small cell lung cancer [PDF]

Frontiers in Immunology
BackgroundThe response rate to immune checkpoint blockade (ICB) in non-small cell lung cancer (NSCLC) varies significantly among individuals. Cancer-associated macrophages (TAMs) are key components of the tumor immune microenvironment (TIME), influencing

CYP27A1 expression is associated with risk of late lethal estrogen receptor-positive breast cancer in postmenopausal patients

Breast Cancer Research, 2020
Background 27-Hydroxycholesterol (27HC) stimulates estrogen receptor-positive (ER+) breast cancer (BC) progression. Inhibiting the sterol 27-hydroxylase (CYP27A1) abrogates these growth-promoting effects of 27HC in mice.

2 Novel deletions of the sterol 27-hydroxylase gene in a Chinese Family with Cerebrotendinous Xanthomatosis [PDF]

BMC Neurology, 2011
Background Cerebrotendinous xanthomatosis (CTX) is a rare lipid-storage disease. We investigated the clinic manifestation, histopathology and sterol 27-hydroxylase gene (CYP27A1) in a Chinese family with Cerebrotendinous Xanthomatosis (CTX).

Heterozygous CYP27A1 gene mutation presenting with Achilles tendon xanthoma: a case report [PDF]

Journal of Medical Case Reports
Background Cerebrotendinous xanthomatosis is a rare autosomal recessive lipid storage disorder involving bile acid biosynthesis. Reduced mitochondrial cytochrome P450 enzyme activity leads to abnormal lipid accumulation in various tissues, especially ...

CYP27A1-27-hydroxycholesterol axis in the respiratory system contributes to house dust mite-induced allergic airway inflammation

Allergology International
Background: 27-Hydroxycholesterol (27-HC) derived from sterol 27-hydroxylase (CYP27A1) has pro-inflammatory biological activity and is associated with oxidative stress and chronic inflammation in COPD.

Proteomic and experimental analyses reveal molecular signatures of flexural atopic dermatitis in antecubital and popliteal fossae and the therapeutic effect of Aida lotion [PDF]

Frontiers in Immunology
IntroductionThe mechanisms underlying the predilection of atopic dermatitis for the antecubital and popliteal fossae remain unexplored. This preliminary exploratory study aimed to characterize the proteomic features of typical flexural atopic dermatitis ...

Genetic variants in the vitamin D pathway genes are predictors of the risk of diabetic kidney disease in Central Asian Kazakhstani cohort with type 2 diabetes [PDF]

Frontiers in Medicine
IntroductionDiabetic kidney disease (DKD) is a common microvascular complication of type 2 diabetes mellitus (T2DM). Given vitamin D’s roles in glucose metabolism and renal function, this study investigated associations between common variants in vitamin
