Overview

Information

Estriol (NSC-12169) is an antagonist of the G-protein coupledestrogen receptorin estrogen receptor-negative breast cancer cells.
In vitro

MTT assays using G-1 shows that, in SkBr3 cells, the proliferative effect induced by 100 nM G-1 is abolished in the presence of 1 μM estriol which acts as an antagonist of GPR30-dependent pathway. A cell-free transcription assay demonstrates that the antiestrogenic activity exhibited by estriol is because of interferring with estradiol-induced positive cooperative binding and receptor dimerization, binding of hER complexes to ERE, as well as reducing estradiol-dependent transcription in a dose-dependent manner. A recent study shows that estrogen (estrone, estradiol, and estriol) inhibits Alzheimer\'s disease-associated low-order Aβ oligomer formation, and among them, estriol shows the strongest in vitro activity.

In vivo

In mPTEN+/- mice, estriol treatments resulted in a 187.54% gain in the relative ratio of uterine wet weight to body weight; estriol also increases the ratio to 176.88% in wild-type mice. Estriol treatment (20 mg/kg ip), in vivo, sensitizes Kupffer cells to LPS via mechanisms dependent on an increase in CD14 by elevated portal blood endotoxin caused by increased gut permeability in rats; while one-half of the rats given estriol intraperitoneally 24 hours before an injection of a sublethal dose of LPS (5 mg/kg) died within 24 hours.
