Neural Tube Defects (NTDs) such as spina bifida and anencephaly are due to incomplete closure of neural tubes in developing embryos. While the etiology is still unknown, environmental and genetic factors, toxicants, and maternal health are implicated as potential causes. Previous research shows that NTDs are associated with increased levels of ceramide (C2) and possible exposure to fumonisin (FB1), and valproic acid (VPA). We hypothesize that these molecules may interfere with cell-to-cell interactions which are important for neural tube formation. To investigate the potential mechanisms by which these toxicants can induce NTDs, I will use a well-characterized MDCK cell model treated with C2, FB1, and VPA to assess their impact on cell adhesion.
