To test this hypothesis Angus crossbred heifers (n = 46; \u223c15 mo of age; BW = 363 \u00b1 35 kg) were fed native grass hay, supplemented with cracked corn to gain 0.3 kg\/d, and given ad libitum access to water. All heifers were subjected to a 5-d CO-Synch + CIDR estrous synchronization protocol and AI (breeding = d 0). Ovariohysterectomies were performed on d 16, 22, 28, 34, 40, and 50 of gestation and at d 16 of the estrous cycle for non-pregnant (NP) controls. Utero-placental tissues [maternal caruncle (CAR); maternal intercaruncular endometrium (ICAR); and fetal membranes, (FM, chorion on d 16, chorioallantois on d 22 to 50)] were collected from the uterine horn ipsilateral to the corpus luteum (CL). Tissues were flash frozen and stored at \u201380\u00b0C. Expression of mRNA was evaluated using qPCR. In CAR, syncytin-Rum1 expression was greater (P &amp;lt; 0.01) on d 50 (81.5-fold) compared with NP controls or any other day of early pregnancy. In contrast, syncytin-Rum1 expression in I-CAR only tended (P = 0.09) to change across days of early pregnancy and did not differ (P = 0.27) in FM tissues. In CAR, the expression of BERV-K1 was not different (P &amp;gt; 0.79) at d 16 and 22, was intermediate at d 28, 34, and 40, and was greatest on d 50 (108-fold increase compared with NP). Expression of BERV-K1 in FM was increased (P &amp;lt; 0.01) on d 28, 34, and 50 compared with NP controls, but at d 40 did not differ from NP controls. The mRNA expression of IFN-\u03c4 in FM at d 22 was greater (P &amp;lt; 0.01) than all other days of gestation. In CAR, expression of PAG-1 increased (P &amp;lt; 0.001) dramatically on d 40 (20,000-fold) and d 50 (86,000-fold) compared with NP heifers (P &amp;lt; 0.01). In ICAR, expression of PAG-1 was greater (P &amp;lt; 0.05) on d 28 and 40 (fold increases of 113 and 102, respectively, compared with NP). Insulin concentrations were not different (P = 0.53) but progesterone was greater (P &amp;lt; 0.01) on d 16, 22, 28, 34, and 40 compared with d 50 of gestation. These data confirm differential ERV, IFN-\u03c4, and PAG-1 gene expression during critical time points of early gestation in utero-placental tissues.<\/jats:p>","DOI":"10.2527\/tas2017.0026","type":"journal-article","created":{"date-parts":[[2018,12,11]],"date-time":"2018-12-11T22:05:51Z","timestamp":1544565951000},"page":"239-249","source":"Crossref","is-referenced-by-count":6,"title":["Endogenous retroviral gene elements (syncytin-Rum1 and BERV-K1), interferon-\u03c4, and pregnancy associated glycoprotein-1 are differentially expressed in maternal and fetal tissues during the first 50 days of gestation in beef heifers1"],"prefix":"10.1093","volume":"1","author":[{"given":"K.
