Altered progesterone responsiveness leads to female infertility and cancer, but underlying mechanisms remain unclear. Mice with uterine-specific ablation of GATA binding protein 2 (Gata2) are infertile, showing failures in embryo implantati…

In order to understand the biology of the endometrium and potentially develop new diagnostic tools and treatments for endometrial diseases, the highly orchestrated gene expression/regulation that occurs within the uterus must first be under…

The ovarian steroid progesterone, acting through the progesterone receptor (PR), coordinates endometrial epithelial-stromal cell communication, which is critical for its development and function. PR expression in these cellular compartments…

Conditional ablation of Indian hedgehog (Ihh) in the murine uterus results in mice that are sterile because of defects in embryo implantation. We performed microarray analysis on these mice at the time point at which the Ihh target genes ar…

Previous work has identified Indian hedgehog (Ihh) as a major mediator of progesterone signaling during embryo implantation. Ihh acts through its downstream effector smoothened (Smo) to activate the GLI family of transcription factors. In o…

Endometrial cancer is the most common gynecological cancer. Estrogen-dependent endometrioid carcinoma is the most common type of endometrial cancer, and alterations in the expression of PTEN and K-ras have been associated with this disease.…

Normal endometrial function requires a balance of progesterone (P4) and estrogen (E2) effects. E2 acts to stimulate the proliferation of uterine epithelial cells, while P4 action inhibits E2-mediated proliferation of the epithelium. P4 thro…

In order for a successful pregnancy to occur, the embryo must attach to the luminal epithelial cells and invade into the stroma. Then, the surrounding stromal cells need to undergo decidualization in order to establish the vasculature neces…
