Testis Biology/Reproductive Toxicology
The primary goal of my research is to understand the molecular and cellular mechanisms controlling embryonic and postnatal testis development and sperm production. The first research focus is to determine the role of vitamin A (retinoids) and retinoic acid receptors in stem cell function and meiosis. We are characterizing retinoic acid receptor alpha mutant mice with specific deletion of the receptor in germ cells. The second research focus is to determine the transgenerational mechanism by which phthalate plasticizers, environmental toxins, interfere with stem cell function and meiosis in the testis. To do these, we use state-of-the-art molecular and cellular techniques and in vivo animal model systems such as animals going through embryonic and neonatal development, environmental toxin-treated or vitamin A-deprived rats and mice, and transgenic receptor knockout mice.
