| Research Abstract |
Prevalence of neural tube defects (NTDs) is larger in female in human. Pdn/Pdn mouse, whose responsible gene is Gli3, has a 16% risk of NTDs, and confines in female. When Ochratoxin A (OTA) was exposed to Pdn/Pdn mouse embryo, only male Pdn/Pdn manifested increased incidence of NTDs. After exposure to OTA on day 7.5 of gestation, Daam, Hoxbl, Tbx, Hmx3, Dlxl, Tlxh gene expressions were severely up-regulated in the +/+ and Pdn/Pdn embryos on day 9 of gestation. Ectopic expressions of Fgf8 and Emx2 were observed in the OTA-treated Pdn/Pdn embryos. From these investigations, it was speculated that NTDs manifestation is induced by the altered multiple gene expressions.
