TLDR
This work has defined the 13 bp palindrome GGTCACAGTGACC as a minimal functional estrogen responsive element (ERE), which binds estrogen receptor preferentially in vitro and point mutations within the ERE decrease its affinity for the estrogen receptor and result in a complete loss of estrogen inducibility.
Abstract
Sequences located upstream of the transcription initiation site of the Xenopus vitellogenin A2 (vit A2) gene contain a hormone dependent enhancer that confers estrogen control to the heterologous thymidine kinase (tk) promoter. As a minimal functional estrogen responsive element (ERE), we have defined the 13 bp palindrome GGTCACAGTGACC. This ERE binds estrogen receptor preferentially in vitro. Although the ERE shares some structural features with the glucocorticoid responsive element (GRE) it is distinct from this element since it neither binds glucocorticoid receptor in vitro nor does it confer glucocorticoid inducibility to a fusion gene. Point mutations within the ERE decrease its affinity for the estrogen receptor and result in a complete loss of estrogen inducibility.

Estrogen Abolishes the Repression Role of gga-miR-221-5p Targeting ELOVL6 and SQLE to Promote Lipid Synthesis in Chicken Liver.

TL;DR: The results showed that miR-221-5p was highly conserved among species, expressed in all tested tissues and significantly downregulated in peak-laying hen liver compared to pre-lays hen liver, indicating the highly conservative gga-miR- 221-5P could directly target ELOVL6 and SQLE mRNAs to affect the level of intracellular triglyceride and total cholesterol.

Construction of reporter gene assays using CWP and PDR mutant yeasts for enhanced detection of various sex steroids.

TL;DR: The yeast-based reporter gene assay will be valuable as a primary screening tool to detect and evaluate steroid hormone activities in various test samples and strongly support the detection of agonists, antagonists, and inverse agonists of steroid hormone receptors in the field of novel drug discovery and assessments of environmental pollutants.

Bending of the estrogen response element by polyamines and estrogen receptors α and β: A fluorescence resonance energy transfer study

TL;DR: Polyamine-induced bending of the ERE might be a mechanism for enhancing ERα–ERE binding affinity and thereby fine-tuning the transcriptional response of estrogen-responsive genes.
