Associations of CYP19A1 with chemical compounds

 

Physical interactions of CYP19A1

  • Additionally, beta-catenin is present in transcription complexes assembled on the endogenous gonad-specific CYP19A1 promoter, as evidenced by chromatin immunoprecipitation assays [23].
  • These findings suggest that treatments targeted at growth factor signalling pathways may be useful in patients acquiring resistance to oestrogen deprivation with aromatase inhibitors and that the pure anti-oestrogen ICI 182,780 may also be effective by blocking or destabilizing ER and hence disrupting cross-talk [28].
  • Stimulation of aromatase P450 promoter (II) activity in endometriosis and its inhibition in endometrium are regulated by competitive binding of steroidogenic factor-1 and chicken ovalbumin upstream promoter transcription factor to the same cis-acting element [29].
  • PGE2 increased GATA-4 binding to the Cyp19 promoter [30].
  • Experiments carried out with different models including turtles, crocodilians and lizards have demonstrated the implication of estrogens and the key role played by aromatase (the enzyme complex that converts androgens to estrogens) in ovary differentiation during TSP and in maintenance of the ovarian structure after TSP [31].
 

Enzymatic interactions of CYP19A1

  • Aromatase and cholesterol side-chain cleaving P450 mRNAs, proteins, and activities are measurable in human placentas and do not seem to be affected by maternal cigarette smoking [32].
  • In human placenta the enzyme complex aromatase catalyzes the conversion of androgens to estrogens and 17 beta-hydroxysteroid dehydrogenase (17 beta-HSD) mediates the reversible interconversion of, e.g. estrone to estradiol [33].
 

Regulatory relationships of CYP19A1

 

Other interactions of CYP19A1

  • In the second trimester, increased O(2) tension promotes proteasomal degradation of USF1/2, resulting in syncytiotrophoblast differentiation and induction of hCYP19 expression [3].
  • Overexpression of Mash-2 prevents syncytiotrophoblast differentiation and induction of CYP19 expression [39].
  • The aromatase activity in the ER alpha-transfected SK-BR-3 cells could also be induced by environmental chemicals that were known to have an estrogen-like activity [4].
  • The aromatase C/C genotype together with a longer AR was also more frequent among controls (55%) than cases (41%; age- and BMI-adjusted OR, 0.51; 95% CI, 0.30-0.89) [40].
  • These results were consistent with enzyme activity data, suggesting that the effect of COX inhibitors on aromatase begins at the transcriptional level [34].
  • In endometrial stromal cells and the human endometrial surface epithelial (HES) cell line, induction of aromatase mRNA by A4 was associated with increased expression of SF-1 [41].
