Identification of Authentic Estrogen Receptor in Cultured Endothelial Cells: A Potential Mechanism for Steroid Hormone Regulation of Endothelial Function
Abstract
Background Estrogen plays a major role in the delayed expression of coronary heart disease (CHD) in women, and recent data indicate that postmenopausal estrogen therapy reduces the incidence of CHD by >40%. The mechanism or mechanisms through which estrogen exerts this benefit are unknown, although effects on blood pressure, carbohydrate and lipid metabolism, and coagulation have been suggested. We hypothesized that at least part of the effect of estrogen in reducing the incidence of CHD is due to an effect on endothelial cell function. Methods and Results In the present study, we examined human aortic and umbilical vein endothelial cells and bovine aortic endothelial cells for the presence of estrogen receptors (ERs) through immunoblot and mRNA analyses. Electrophoretic mobility shift assays were also performed to determine the DNA-binding properties of the putative ERs. Nuclear extracts from all three endothelial cell types were found to contain a 67-kD protein that reacted with anti-ER monoclonal antibodies specific to different domains of the ERs. Each of these types of cells expresses proteins that bind specifically to consensus estrogen-responsive elements. Finally, Northern blots verified that endothelial cells express abundant amount of mRNA for the ER. Conclusions These data indicate that endothelial cells constitutively possess the potential for transcriptional regulation of target genes by estrogen. The evolutionary conservation of this receptor in bovine and human endothelial cells suggests a common mechanism for estrogen regulation of endothelial function.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
