Research Interests

Research in the Sulik laboratory is directed toward achieving a better understanding of the mechanisms and pathogenesis associated with a variety of environmentally-induced or genetically-based birth defects. Our interest in modeling human genetic malformation syndromes and opportunities for collaborative efforts with molecular geneticists who have produced transgenic mice and mice with targeted gene modifications have proven productive in our attempt to better understand the developmental basis for a variety of severe malformations of the brain including anencephaly, holoprosencephaly, and hydrocephaly. Focusing on teratogens of significant human relevance, we have identified selected cell populations that are particularly vulnerable to insult at specific embryonic developmental stages. Of special interest are malformations involving the craniofacial region, including failure of the neural tube to close. Since neural crest cell populations play a key role in the genesis of many of the induced malformations, we have focused on characteristics of this cell population that impart its selective vulnerability to a variety of teratogens as well as genetically-based disturbances. Studies in progress include examination of the genesis of a wide spectrum of CNS abnormalities in an animal model for fetal alcohol syndrome. Additionally, we are utilizing an alcohol self administration mouse model to test agents, including selected antioxidants, that can ameliorate alcohol's teratogenicity. Among the methodologies currently used in this lab are whole embryo culture, confocal microscopy, in situ hybridization, microarray and proteomic analyses, and high resolution magnetic resonance imaging.
