REV-ERBα Inhibits the PTGS2 Expression in Bovine Uterus Endometrium Stromal and Epithelial Cells Exposed to Ovarian Steroids
REV-ERBα reduces PTGS2 levels in cow uterine support and lining cells exposed to ovarian hormones

Abstract
The expression of REV-ERBα is significantly altered in bovine uterine stromal and epithelial cells exposed to ovarian steroids.
- Clock genes in bovine uterine cells exhibit weaker circadian oscillation compared to those in rodents.
- Prostaglandin F2α (PGF2α) secretion from uterine stromal cells is linked to the expression of the PTGS2 gene.
- Treatment with progesterone suppresses PTGS2 expression in uterine stromal cells, whereas estradiol initially suppresses and then increases PTGS2 expression in epithelial cells.
- Knockdown of BMAL1 leads to decreased levels of NR1D1 and PTGS2 transcripts in uterine stromal cells, but not in epithelial cells.
- REV-ERBα antagonists increase PTGS2 expression in both cell types, while agonists have no effect.
