Background： This study evaluated the impact of hormonal modulation at the onset of proestrus on ovarian response and uterine gene expression of beef ***： A total of 172 anestrous beef cows were assigned to one of four groups according to the treatment with estradiol cypionate（ECP） and/or equine chorionic gonadotropin（eCG） [CON（n = 43）, ECP（n = 43）, eCG（n = 44）and ECP ＋ eCG（n = 42）].Results： ECP-treated cows（ECP and ECP ＋ eCG groups） presented greater occurrence of estrus（44.6% vs. 65.4%; P = 0.01） and pregnancy per AI [47.1% vs. 33.3%; P = 0.07], but similar progesterone（P4） concentration at subsequent diestrus than cows not treated with ECP（CON and eCG groups）. Nonetheless, eCG-treated cows（eCG and ECP ＋ eCG groups） presented larger follicle at timed AI（12.6 ± 0.3 vs. 13.5 ± 0.3 mm; P = 0.03）, greater ovulation rate（96.5%vs. 82.6%; P = 0.008） and greater P4 concentration at d 6（3.9 ± 0.2 vs. 4.8 ± 0.2 ng/mL; P = 0.001） than cows not treated with eCG（CON and ECP groups）. Next, cows with a new corpus luteum 6 d after TAI were submitted to uterine biopsy procedure. Uterine fragments [CON（n = 6）, ECP（n = 6）] were analyzed by RNA-Seq and a total of 135 transcripts were differentially expressed between groups（73 genes up-regulated by ECP treatment）. Subsequently,uterine samples were analyzed by q PCR（genes associated with cell proliferation）. ECP treatment induced greater abundance of PTCH2（P = 0.07） and COL4 A1（P = 0.02）, whereas suppressed EGFR（P = 0.09） expression. Conversely, eCG treatment increased abundance of HB-EGF（P = 0.06）, ESR2（P = 0.09）, and ITGB3（P = 0.05）, whereas it reduced transcription of ESR1（P = 0.05）. Collectively, supplementation with ECP or eCG at the onset of proestrous of anestrous beef cows influenced ovarian responses, global and specific endometrial gene ***： Proestrus estradiol regulate the endometrial transcriptome, particularly stimulating proliferative activity in the endometrium.
