Comparison of the global gene expression profiles in the bovine endometrium between summer and autumn.

ABSTRACT: Heat stress compromises fertility during summer in dairy and beef cows by causing nutritional, physiological and reproductive damages. To examine the difference in endometrial conditions in cows between summer and autumn, gene expression profiles were compared using a 15 K bovine oligo DNA microarray. The trial was conducted in the summer (early in September) and autumn (mid-November) seasons of two consecutive years (2013-2014) in Morioka, Japan. Endometrial samples were collected from the cows using a biopsy technique. The expressions of 268 genes were significantly higher in the endometrium collected in summer than those collected in autumn, whereas the expressions of 369 genes were lower (P<0.05 or lower). Messenger RNA expressions of glycoprotein 2 (GP2), neurotensin (NTS),E-cadherin
