Multiplicity of 3-Ketosteroid-9α-Hydroxylase Enzymes in Rhodococcus rhodochrous DSM43269 for Specific Degradation of Different Classes of Steroids [PDF]

, 2011
The well-known large catabolic potential of rhodococci is greatly facilitated by an impressive gene multiplicity. This study reports on the multiplicity of kshA, encoding the oxygenase component of 3-ketosteroid 9α-hydroxylase, a key enzyme in steroid ...

Changes in the levels of cerebral and extracerebral sterols in the brain of patients with Alzheimer's disease

Journal of Lipid Research, 2004
24S-hydroxycholesterol is a side-chain oxidized oxysterol formed in the brain that is continuously crossing the blood-brain barrier to reach the circulation. There may be an opposite flux of 27-hydroxycholesterol, which is formed to a lower extent in the

Novel homozygous and compound heterozygous mutations of sterol 27-hydroxylase gene (CYP27) cause cerebrotendinous xanthomatosis in three Japanese patients from two unrelated families

Journal of Lipid Research, 1997
The autosomal recessively inherited cholesterol metabolic disease, cerebrotendinous xanthomatosis (CTX), is caused by mutations in the sterol 27-hydroxylase gene. Three Japanese CTX patients from two unrelated families were studied genetically.

Elimination of cholesterol as cholestenoic acid in human lung by sterol 27-hydroxylase: evidence that most of this steroid in the circulation is of pulmonary origin

Journal of Lipid Research, 1999
Human alveolar macrophages have exceptionally high capacity to convert cholesterol into 27-hydroxycholesterol and cholestenoic acid by the sterol 27-hydroxylase mechanism. It is shown here that the human lung has a higher content of 27-hydroxycholesterol

On the substrate specificity of human CYP27A1

Journal of Lipid Research, 2003
The mitochondrial sterol 27-hydroxylase (CYP27A1) is required for degradation of the C27-sterol side chain in bile acid biosynthesis. CYP27A1 seems, however, to have roles beyond this, as illustrated by patients with a deficient sterol 27-hydroxylase due

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

Journal 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.

Ethnic differences in the prevalence of polymorphisms in CYP7A1, CYP7B1 AND CYP27A1 enzymes involved in cholesterol metabolism

Journal of Pharmacy and Bioallied Sciences, 2011
It is well known that drug disposition and response are greatly determined by the activities of drug metabolizing enzymes, which are polymorphic.

Molecular genetics of cerebrotendinous xanthomatosis in Jews of north African origin.

Journal of Lipid Research, 1994
Cerebrotendinous xanthomatosis (CTX) is an autosomal recessive sterol storage disease characterized by the accumulation of a bile alcohol, cholestanol, in diverse tissues.

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.

Effects of cyclosporin on cholesterol 27-hydroxylation and LDL receptor activity in HepG2 cells.

Journal of Lipid Research, 1996
The hypothesis that mitochondrial sterol 27-hydroxylase plays a role in the sterol-mediated down-regulation of LDL receptor activity was evaluated in HepG2 cells. 27-Hydroxycholesterol was found to be more potent at suppressing LDL receptor activity than
