| Research Abstract |
We explored a novel gene that is involved in endodermal differentiation by using a human iPS cell-differentiation system. We found that expression of Runx1 gene was disappeared when cells were differentiated from the mesendoderm stage to definitive endoderm stage. Also, Runx1 could negatively regulate the expression of endoderm-specific genes, such as Foxa2 and Sox17, by directly binding the regulatory regions of their genes. In contrast, when the function of Runx1 was inhibited by its dominant-negative mutant, expression levels of Foxa2, Sox17, GATA4 genes were increased. Therefore, Runx1 is important for not only mesoderm differentiation but also endoderm differentiation.
