Disease relevance of ESR1

  • The antiproliferative effects of the four hydroxyferrocifens with n=2, 3, 5 and 8 were studied on four breast cancer cell lines (MCF7, MDA-MB231, RTx6 and TD5) possessing different levels of ERalpha [1].

Associations of ESR1 with chemical compounds

  • Furthermore, antagonists that are selectively effective on ERbeta can have structures that are very different from the typical antiestrogens tamoxifen and raloxifene, which are antagonists on both ERalpha and ERbeta [13].
  • ESR1 mRNA was increased in ewes treated with progesterone and estradiol plus progesterone [10].
  • Differential expression of myometrial oxytocin receptor and prostaglandin H synthase 2, but not estrogen receptor alpha and heat shock protein 90 messenger ribonucleic acid in the gravid horn and nongravid horn in sheep during betamethasone-induced labor [14].
  • Cysteine 530 of the human estrogen receptor alpha is the main covalent attachment site of 11beta-(aziridinylalkoxyphenyl)estradiols [15].
  • Wild-type human ERalpha was alkylated as efficiently as lamb ER, whereas the quadruple cysteine --> alanine mutant, in which all cysteines of the hormone-binding domain (residues 381, 417, 447, and 530) were changed to alanines, showed no significant electrophile labeling [15].
 

Other interactions of ESR1

  • Overexpression of ovine IRF-2, but not IRF-1, inhibited transcriptional activity of several regions of the ovine ERalpha promoter containing an IRFE or an ISRE as well as some, but not all, regions lacking these elements [8].
  • Higher levels of PCNA and ER-alpha expression were detected in GE at the tips of developing glands as well as in the surrounding stroma [16].
  • Similarly, few somatotropes express ERalpha, suggesting a weak pituitary effect of estradiol on GH [17].
  • Using immunocytochemical approaches, the present study revealed that although somatostatin neurons were located in several hypothalamic sites, only those in the arcuate nucleus (13% +/- 2%) and ventromedial nucleus (VMN; 29% +/- 1%) expressed ERalpha [17].
  • Results support the hypothesis that neonatal ovine uterine development involves epithelial PRL-R and ER-alpha activation to stimulate and maintain endometrial gland genesis and branching morphogenesis [16].
