A disintegrin and metalloproteinase with thrombospondin motifs 1 (ADAMTS1) is a secreted protease. Through the regulation of extracellular matrix remodeling or developmental processes or both, ADAMTS1 is involved in several biological functions, including ovulation and embryo receptivity. However, the expression and possible role of ADAMTS1 in bovine endometrium is unknown. In this study, we analyzed ADAMTS1 mRNA expression in bovine endometrium during the estrous cycle, peri-implantation period, and at different stages of gestation by using quantitative real-time RT-PCR (qPCR) and in situ hybridization. The qPCR results indicated that the expression of ADAMTS1 mRNA was not affected by the day of the estrous cycle and was similar to cyclic levels on day 35 of gestation; however, the expression was more abundant in cotyledonary tissues of the placenta during late gestation. The in situ hybridization study showed that ADAMTS1 mRNA was detected mainly in uterine luminal epithelia and stromal cells during the estrous cycle and peri-implantation period. A disintegrin and metalloproteinase with thrombospondin motifs 1 mRNA was also expressed in the peri-implantation conceptus as well as in trophoblast cells, which include binucleate cells, and increased during late gestation. Furthermore, treatment of stromal cell with progesterone (300 nM) stimulated the expression of ADAMTS1 mRNA. This study indicates that ADAMTS1 participates in bovine endometrial remodeling, which is required for implantation and placental development in coordination with ovarian steroids.
