Our lab uses genetically engineered mouse models to investigate two aspects of uterine biology. One of our projects looks at the nongenomic actions of natural estrogen and xenoestrogens in the uterus outside of their interactions with traditional estrogen receptors. Our second project investigates cell cycle regulation in the uterus as it pertains to decidualization during embryo implantation.
One branch of our research investigates the nongenomic actions of natural estrogen and xenoestrogens in the uterus, exclusive of known estrogen receptors.
We also examine aspects of uterine cell cycle regulation of decidualization in implantation.
