| Outline of Final Research Achievements |
The present study aimed to analyze genes whose expression is induced by embryos and to identify embryonic secretory factors that induce gene expression in cattle. Analysis of the embryonic secretory factor of bovine elongated embryo by LC / MS / MS resulted in the identification of 6 cytokines and 2 growth factors. Furthermore, from the results obtained by RNAseq analysis, upstream factors were analyzed for genes whose expression increased in the endometrium of the implantation period. As a result, in addition to IFNT, genes considered to be controlled by MIF was included. These results suggested that MIF might control endometrial function during implantation as an embryonic secretory factor other than IFNT.
