| Outline of Final Research Achievements |
Placental function plays important roles in the fetal growth. Ezrin is a regulatory gene for plasma membrane proteins in the placenta, and deficiency of ezrin induces fetal growth retardation (FGR). This study aimed to clarify a gene network between ezrin and the other genes responsible for FGR by means of informatics and experiments in order to understand the molecular mechanism of the ezrin-mediated FGR. Network analysis showed no direct relationship between ezrin and the known FGR-related genes, indicating that ezrin-mediated FGR includes the novel molecular mechanism. We further analyzed protein interaction between Ezrin and a hypotaurine transporter, SLC6A13 in the placenta, since Ezrin knockout fetal mice showed deficiency of hypotaurine. Ezrin and SLC6A13 are co-localized on the plasma membrane in the labyrinth zone of mouse placenta. These results indicate that a novel interaction between Ezrin and SLC6A13 is important for fetal growth.
