Research Abstract |
Nucleotide sequence of Bovine BRCA1 gene was highly conserved between Holstein cows and Japanese Black cows. Expression of Brca1 was strongly upregulated in implantation-competent blastocysts in the mouse, whereas the Brca1 expression of was low in blastocysts derived from in vitro fertilization. In contrast, 4-hydroxyestradiol and prolactin upregulated Brca1 levels in blastocysts derived from in vitro fertilization. Our results suggest that Brca1 most likely plays a physiological role indirecting implantation-competent blastocysts in the mouse.
