Identification of multiple CYP19 genes encoding different cytochrome P450 aromatase isozymes in brain and ovary.
Evidence to date indicates that the gene encoding cytochrome P450 aromatase (P450arom) in humans is a single member of the CYPl9 family, but multiple CYPl9 loci and isoforms have been identified in pigs. Here we report the cloning and characterization of a second member of the CYP19 family in goldfish. A search for P450arom variants was prompted by studies showing that a full-length P450arom co...
متن کاملAlternatively spliced transcripts of the aromatase cytochrome P450 (CYP19) gene in adipose tissue of women.
Estrogen biosynthesis in adipose tissue has assumed great significance in terms of a number of estrogen-related diseases. The biosynthesis of estrogens from C19 steroids is catalyzed by a specific form of cytochrome P450, namely aromatase cytochrome P450 (P450arom; the product of the CYP19 gene). The human CYP19 gene comprises nine coding exons, II-X, and its transcripts are expressed in the ov...
متن کاملPolymorphisms in the human aromatase cytochrome P450 gene (CYP19) and breast cancer risk.
The aromatase enzyme catalyses the conversion of androgens to oestrogens in the oestrogen biosynthesis pathway. Because increased exposure to oestrogens is considered to be a risk factor for breast cancer, the human aromatase gene (CYP19) is a plausible candidate for low penetrance breast cancer susceptibility. Preliminary reports have suggested that specific alleles of a TTTA repeat may be ass...
متن کاملCytochrome P450 aromatase expression in human seminoma
BACKGROUND The enzyme cytochrome P450 aromatase, catalysing the conversion of androgens into estrogens, has been detected in normal human testicular cells suggesting a physiological role of local estrogen biosynthesis on spermatogenesis control. Estrogens, regulating cell growth and apoptosis, can also be involved in tumorigenesis process, but the possible link between estrogens and testicular ...
متن کاملCloning and gene expression of cytochrome P450 gene from Alcanivorax borkumensis Bacterium
Alcanivorax borkumensis is a marine bacterium that has ability to grow on limited substrates that mainly is alkanes. The ability to use wide range of hydrocarbons is advantage of this bacterium to other marine community bacteria. A. borkumensis have two genetic systems for alkane biodegradation. The First system is alkane hydroxylase (alk-B1and alk-B2) and the second system is...
