Abstract

In preparation for embryo implantation and pregnancy, the uterine epithelium undergoes a genomic and biological transition that mediates adhesion and invasion of the blastocyst. These events resemble an inflammatory response, and the immune system likely takes an active role in the establishment and maintenance of pregnancy. Although glucocorticoids are primary mediators of the immune system, the functional role of glucocorticoid signaling in the uterine epithelium is not well defined. To investigate the dynamic relationship between glucocorticoids and reproductive hormones, we performed whole-genome microarray analysis in a human uterine endometrial cancer cell line (ECC1 cells) treated with the synthetic glucocorticoid dexamethasone (Dex) alone or in combination with estradiol (E₂). Over 10,000 genes were significantly regulated in the presence of Dex and/or E₂. Surprisingly, unique targets of Dex and E₂ together represented the largest group of regulated genes. Ingenuity pathway analysis found both overlapping and independent regulated networks for each hormone. Several hundred genes were found to be coregulated by Dex and E₂, including several that were antagonistically regulated. The effects of glucocorticoids and E₂ are mediated primarily through the glucocorticoid receptor (NR3C1) and estrogen receptor (ESR1), respectively. In silico promoter analysis revealed that NR3C1 and ESR1 response elements are enriched in antagonistically regulated genes, and signaling through these receptors was required for antagonism. Glucocorticoid and E₂ antagonism of target genes may represent a critical junction between the immune system and female reproductive system. Moreover, identification and ontology analysis of glucocorticoid-regulated genes in a uterine epithelial-like cell line suggests that glucocorticoid signaling regulates important biological functions, including immune cell trafficking and embryonic development.

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.
