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

open access: yesBreast 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.

27-Hydroxylation of oncosterone by CYP27A1 switches its activity from pro-tumor to anti-tumor

open access: yesJournal of Lipid Research, 2023
Oncosterone (6-oxo-cholestane-3β,5α-diol; OCDO) is an oncometabolite and a tumor promoter on estrogen receptor alpha-positive breast cancer (ER(+) BC) and triple-negative breast cancers (TN BC). OCDO is an oxysterol formed in three steps from cholesterol:

Increased maternal and fetal cholesterol efflux capacity and placental CYP27A1 expression in preeclampsia[S] [PDF]

open access: yesJournal of Lipid Research, 2017
Preeclampsia is a pregnancy-specific condition that leads to increased cardiovascular risk in later life. A decrease in cholesterol efflux capacity is linked to CVD.

Hormonal Regulation of the Human CYP27A1 and CYP7B1 Genes [Elektronisk resurs]

open access: yes, 2007
CYP27A1 and CYP7B1 are widely expressed in various human tissues and are two key enzymes involved in the pathways for conversion of cholesterol to bile acids.

Transcriptomic analysis identifies CYP27A1 as a diagnostic marker for the prognosis and immunity in lung adenocarcinoma

open access: yesBMC Immunology, 2023
Background The association between lipid metabolism disorder and carcinogenesis is well-established, but there is limited research on the connection between lipid metabolism-related genes (LRGs) and lung adenocarcinoma (LUAD).

Hepatic caveolin-1 is enhanced in Cyp27a1/ApoE double knockout mice [PDF]

open access: yes, 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

Activity of 25-hydroxylase in human gingival fibroblasts and periodontal ligament cells. [PDF]

open access: yesPLoS ONE, 2012
We previously demonstrated that 25-hydroxyvitamin D(3) concentrations in gingival crevicular fluid are 300 times higher than those in the plasma of patients with aggressive periodontitis. Here we explored whether 25-hydroxyvitamin D(3) can be synthesized

Gene supplementation of CYP27A1 in the liver restores bile acid metabolism in a mouse model of cerebrotendinous xanthomatosis

open access: yesMolecular Therapy: Methods & Clinical Development, 2021
Cerebrotendinous xanthomatosis (CTX) is an autosomal recessive disease caused by mutations in the CYP27A1 gene, encoding the sterol 27-hydroxylase. Disruption of the bile acid biosynthesis pathway and accumulation of toxic precursors such as cholestanol ...

PXR induces CYP27A1 and regulates cholesterol metabolism in the intestine

open access: yesJournal of Lipid Research, 2007
Mitochondrial sterol 27-hydroxylase (CYP27A1) catalyzes oxidative cleavage of the sterol side chain in the bile acid biosynthetic pathway in the liver and 27-hydroxylation of cholesterol in most tissues. Recent studies suggest that 27-hydroxycholesterol (

CYP27A1抑制膀胱癌细胞增殖及作用机制研究

open access: yesZhongguo shiyan zhenduanxue, 2021
目的 研究CYP27A1对膀胱癌细胞的影响及其作用机制。方法 qRY-PCR检测膀胱癌细胞中AR和CYP27A1的mRNA水平;采用转染的实验技术使T24细胞稳定表达CYP27A1;MTT实验检测CYP27A1和27-HC对膀胱癌细胞增殖的影响;裸鼠移植瘤模型检测CYP27A1对膀胱癌细胞增殖的影响;ELIAE检测细胞上清液中27-HC的含量。结果 T24细胞中AR处于高表达水平CYP27A1处于低表达水平,5637细胞中AR处于低表达水平,CYP27A1处于高表达水平 ...
