Gene expression in bovine endometrium at different period after parturition

In order to clarify whether the term after calving is a factor to affect the gene expression in the endometrium of cows, we conducted global endometrial gene expression analysis at different period after parturition. In bovine endometrium between 60.1 ± 4.0 days and 388.9 ± 8.2 days after parturition, the gene expression pattern was similar and the differentially expressed (>2-fold difference, P<0.05) genes were only 4 genes. To clarify the gene expression in bovine endometrium at different period after parturition, 10 female cows were used. The endometrial tissues were collected twice from the same individual on both 42 - 86 (mean 60.1 ± 4.0) days and 343 - 436 (mean 388.9 ± 8.2) days after parturition. During each period, on 7 days after estrus, endometrial tissue of the uterine horn ipsilateral to the corpus luteum was obtained using uterine biopsy forceps.
