Understanding the molecular mechanisms regulating normal physiology and disease development in the uterus and lung is critical in understanding causes and treatments for reproductive and pulmonary disorders. In the investigation of the regulation of reproductive biology we have focused on major regulators of female reproductive tract homeostasis, the ovarian steroids progesterone and estrogen. Utilizing genetically engineered mouse models, high content transcriptomic and cistromic analysis along with primary human samples we have sought to understand the factors that: Regulate the preparation of the uterus for embryo implantation;. Allow the uterus to support embryo invasion and fetal growth and allow the uterus to deliver the fetus at the appropriate time during pregnancy. Towards these goals we have identified the paracrine signaling pathways that regulate uterine epithelial-stroma crosstalk in controlling uterine epithelial cell proliferation and receptivity for embryo attachment. We have identified the role of nuclear receptors and transcription factors governing differentiation of human endometrial stroma cells during pregnancy and have begun identifying the role of progesterone in the regulation of myometrial function. In the process we have generate several models for infertility and endometrial cancer. Our investigation of pulmonary biology have recently focused on understanding the molecular events regulating the progression and metastasis of lung cancer. In the process we have created several genetically engineered mouse models for the various types of lung cancer. The goal of establishing these in vivo models will serve as biosensors to understand how the environment interacts with specific molecular pathways in modulating normal physiology and disease development.
