Simintiras, José M. Sánchez, Michael McDonald & Patrick Lonergan Conceptus elongation coincides with one of the periods of greatest pregnancy loss in cattle and is characterized by rapid trophectoderm expansion, commencing ~ Day 13 of pregnancy, i.e. before maternal pregnancy recognition. The process has yet to be recapitulated in vitro and does not occur in the absence of uterine gland secretions in vivo. Moreover, conceptus elongation rates are positively correlated to systemic progesterone in maternal circulation. It is, therefore, a maternally-driven and progesterone-correlated developmental phenomenon. This study aimed to comprehensively characterize the biochemical composition of the uterine luminal fuid on Days 12–14 – the elongation- initiation window – in heifers with normal vs. high progesterone, to identify molecules potentially involved in conceptus elongation initiation. Specifcally, nucleotide, vitamin, cofactor, xenobiotic, peptide, and energy metabolite profles of uterine luminal fuid were examined. A total of 59 metabolites were identifed, of which 6 and 3 displayed a respective progesterone and day efect, whereas 16 exhibited a day by progesterone interaction, of which 8 were nucleotide metabolites.

Abstract Maternal recognition of pregnancy in ruminants is a physiological process that requires an interaction between the conceptus and the mother in order to avoid luteal regression. Studies on 60’s started to investigate the communication, and late on the 80’s it was identified a Type I interferon called interferon tau. In the 90’s the local action of interferon tau was described. It suppresses luteolytic pulses of prostaglandin F2 alpha inhibiting endometrial expression of estrogen and oxytocin receptors. Several studies presented the expression of interferon- stimulated genes on extrauterine tissues. After, the endocrine action of interferon tau was described. This study revealed a greater interferon bioactivity in the serum of uterine vein from pregnant ewes when compared to non- pregnant ewes. Following a series of experiments were preformed to better understand the endocrine action of interferon tau in several extrauteine tissues. This review presents the endocrine action of interferon tau during maternal recognition of pregnancy period in ruminants.

  • Interferon Receptor Signaling in Malignancy: a Network of Cellular Pathways Defining Biological Outcomes
    Published OnlineFirst September 12, 2014; DOI: 10.1158/1541-7786.MCR-14-0450 Molecular Cancer Review Research Interferon Receptor Signaling in Malignancy: A Network of Cellular Pathways Defining Biological Outcomes Eleanor N. Fish1 and Leonidas C. Platanias2 Abstract IFNs are cytokines with important antiproliferative activity and exhibit key roles in immune surveillance against malignancies. Early work initiated over three decades ago led to the discovery of IFN receptor activated Jak–Stat pathways and provided important insights into mechanisms for transcriptional activation of IFN- stimulated genes (ISG) that mediate IFN biologic responses. Since then, additional evidence has established critical roles for other receptor-activated signaling pathways in the induction of IFN activities. These include MAPK pathways, mTOR cascades, and PKC pathways. In addition, specific miRNAs appear to play a significant role in the regulation of IFN signaling responses. This review focuses on the emerging evidence for a model in which IFNs share signaling elements and pathways with growth factors and tumorigenic signals but engage them in a distinctive manner to mediate antiproliferative and antiviral responses.

  • Interferon-Tau Exerts Direct Prosurvival and Antiapoptotic

Drum 2, Ketan Shrestha1, Svetlana Farberov1, Milo C. Wiltbank3, Roberto Sartori2 & Rina Meidan 1 Interferon-tau (IFNT), serves as a signal to maintain the corpus luteum (CL) during early pregnancy in domestic ruminants. We investigated here whether IFNT directly afects the function of luteinized bovine granulosa cells (LGCs), a model for large-luteal cells. Recombinant ovine IFNT (roIFNT) induced the IFN-stimulated genes (ISGs; MX2, ISG15, and OAS1Y). IFNT induced a rapid and transient (15– 45 min) phosphorylation of STAT1, while total STAT1 protein was higher only after 24 h. IFNT treatment elevated viable LGCs numbers and decreased dead/apoptotic cell counts. Consistent with these efects on cell viability, IFNT upregulated cell survival proteins (MCL1, BCL-xL, and XIAP) and reduced the levels of gamma-H2AX, cleaved caspase-3, and thrombospondin-2 (THBS2) implicated in apoptosis. Notably, IFNT reversed the actions of THBS1 on cell viability, XIAP, and cleaved caspase-3. Furthermore, roIFNT stimulated proangiogenic genes, including FGF2, PDGFB, and PDGFAR. Corroborating the in vitro observations, CL collected from day 18 pregnant cows comprised higher ISGs together with elevated FGF2, PDGFB, and XIAP, compared with CL derived from day 18 cyclic cows. This study reveals that IFNT activates diverse pathways in LGCs, promoting survival and blood vessel stabilization while suppressing cell death signals. These mechanisms might contribute to CL maintenance during early pregnancy.

  • Chronicling the Discovery of Interferon Tau
    REPRODUCTIONANNIVERSARY REVIEW Chronicling the discovery of interferon tau Fuller W Bazer1 and William W Thatcher2 1Department of Animal Science, Texas A&M University, College Station, Texas, USA and 2Department of Animal Science, University of Florida, Gainesville, Florida, USA Correspondence should be addressed to F W Bazer; Email: [email protected] Abstract It has been 38 years since a protein, now known as interferon tau (IFNT), was discovered in ovine conceptus-conditioned culture medium. After 1979, purification and testing of native IFNT revealed its unique antiluteolyic activity to prevent the regression of corpora lutea on ovaries of nonpregnant ewes. Antiviral, antiproliferative and immunomodulatory properties of native and recombinant IFNT were demonstrated later. In addition, progesterone and IFNT were found to act cooperatively to silence expression of classical interferon stimulated genes in a cell-specific manner in ovine uterine luminal and superficial glandular epithelia. But, IFNT signaling through a STAT1/STAT2-independent pathway stimulates expression of genes, such as those for transport of glucose and amino acids, which are required for growth and development of the conceptus. Further, undefined mechanisms of action of IFNT are key to a servomechanism that allows ovine placental lactogen and placental growth hormone to affect the development of uterine glands and their expression of genes throughout gestation. IFNT also acts systemically to induce the expression of interferon stimulated genes that influence secretion of progesterone by the corpus luteum. Finally, IFNT has great potential as a therapeutic agent due to its low cytotoxicity, anti-inflammatory properties and effects to mitigate diabetes, obesity-associated syndromes and various autoimmune diseases.

We found that interferon-tau derived from conceptus induces expression of STAT1, OAS1, and CXCL10 in ovine maternal spleen, which may be helpful for maternal immune regulation. Abstract: Interferon-tau is a maternal recognition factor in ruminant species, and spleen plays an essential role in regulating innate and adaptive immune responses. However, it is not fully understood that early pregnancy induces expression of interferon stimulated genes (ISGs) in the spleen during early pregnancy in ewes. In this study, spleens were collected from ewes at day 16 of the estrous cycle, and on days 13, 16, and 25 of gestation (n = 6 for each group), and RT-qPCR, western blot and immunohistochemistry analysis were used to detect the expression of signal transducer and activator of transcription 1 (STAT1), 20,50-oligoadenylate synthetase 1 (OAS1), myxovirusresistance protein 1 (Mx1) and C-X-C motif chemokine 10 (CXCL10).

In cows, interferon-tau (IFNT) regulates maternal recognition around days 15–19 after artificial insemination (AI). The present study hypothesized that if key target genes of IFNT are clearly upregulated in earlier stages of pregnancy, these genes could be use as indices of future pregnancy in cows. Therefore, we determined the expression of these genes in peripheral blood mononuclear leukocytes (PBMCs) and polymorphonuclear granulocytes (PMNs) during the maternal recognition period (MRP). Twenty multiparous Holstein cows were subjected to AI on day 0 and categorized into the following groups: pregnancy (Preg, n = 9), embryonic death (ED, n = 5) and non-pregnancy (NP, n = 6). Progesterone levels in the Preg group were higher than those in the NP group on days 12–21. ISG15 and OAS-1 (IFN-stimulated genes: ISGs) mRNA in PBMCs on day 8 was higher in the Preg group than in the NP group, and these mRNAs in PMNs was higher in the Preg group on day 5 than in the NP and ED groups.

IFNT acts as an endocrine factor on the corpus luteum (CL) to induce refractory ability against the luteolytic action of PGF2a. Hypothesising that IFNT may influence not only the uterine environment but also the CL in cows via local or peripheral circulation, we investigated qualitative changes in the CL of pregnant cows during the maternal recognition period (day 16) and the CL of non-pregnant cows. The CL of pregnant animals had a higher number of neutrophils, and the expression of interleukin 8 (IL8) mRNA and its protein was higher as well as compared with the CL of non-pregnant animals. Although IFNT did not affect progesterone (P4) secretion and neutrophil migration directly, it stimulated IL8 mRNA expression on luteal cells (LCs), influencing the neutrophils, resulting in the increased migration of IFNT-activated neutrophils.

We aimed to: (1) discover novel early-pregnancy-induced genes in peripheral blood mononuclear cells (PBMC); and (2) characterize the temporal pattern of early‑pregnancy‑induced transcription of select genes in PBMC and peripheral blood polymorphonuclear cells (PMN). Beef heifers were artifcially inseminated on D0 and pregnancies were diagnosed on D28. On D10, 14, 16, 18, and 20, blood was collected for isolation of PBMC and PMN from heifers that were retrospectively classifed as pregnant (P) or non-pregnant (NP). PBMC samples from D18 were submitted to RNAseq and 220 genes were diferentially expressed between pregnant (P) and non-pregnant (NP) heifers. The temporal abundance of 20 transcripts was compared between P and NP, both in PBMC and PMN. In PBMC, pregnancy stimulated transcription of IFI6, RSAD2, IFI44, IFITM2, CLEC3B, OAS2, TNFSF13B, DMKN and LGALS3BP as early as D18. Expression of IFI44, RSAD2, OAS2, LGALS3BP, IFI6 and C1R in PMN was stimulated in the P group from D18. The novel early-pregnancy induced genes discovered in beef heifers will allow both the understanding of the role of immune cells during the pre‑attachment period and the development of technologies to detect early pregnancies in beef cattle. In cattle, pregnancy success depends on the maintenance of a functional corpus luteum (CL) beyond the time of luteolysis, which normally occurs between days 15 and 18 of the estrous cycle 1,2.

  • Interferon Tau in the Ovine Uterus Gwonhwa Song*, Jae Yong Han*, Thomas E
    J. Anim. Sci. & Technol. 51(6) 471~484, 2009 Interferon Tau in the Ovine Uterus Gwonhwa Song*, Jae Yong Han*, Thomas E. Spencer** and Fuller W. Bazer*, ** WCU Biomodulation Major, Department of Agricultural Biotechnology, and Research Institute for Agriculture and Life Sciences, Seoul National University, Korea*, Department of Animal Science, Center for Animal Biotechnology and Genomics, Texas A&M University, 442 Kleberg Center, 2471 TAMU, College Station, Texas 77843-2471, USA ** ABSTRACT The peri-implantation period in mammals is critical with respect to survival of the conceptus (embryo/fetus and associated extraembryonic membranes) and establishment of pregnancy. During this period of pregnancy, reciprocal communication between ovary, conceptus, and endometrium is required for successful implantation and placentation. At this time, interferon tau (IFNT) is synthesized and secreted by the mononuclear trophectodermal cells of the conceptus between days 10 and 21~25. The actions of IFNT to signal pregnancy recognition and induce or increase expression of IFNT-stimulated genes (ISGs), such as ISG15 and OAS, are mediated by the Type I IFN signal transduction pathway. This article reviews the history, signaling pathways of IFNT and the uterine expression of several IFNT-stimulated genes during the peri-implantation period. Collectively, these newly identified genes are believed to be critical to unraveling the mechanism(s) of reciprocal fetal-maternal interactions required for successful implantation and pregnancy.

Although the endometrium undergoes major cellular changes during peri-implantation, the precise mechanisms regulating goat endometrial receptivity remain unknown. In this study, we investigated the functional roles and signal transduction of the B-cell lymphoma 2 (Bcl-2)-like protein 15 (BCL2L15) in the regulation of endometrial receptivity in vitro. Our results showed that BCL2L15 was up-regulated in goat endometrial epithelial cells (EECs) under progesterone (P4), estradiol (E2), and interferon-tau (IFN-τ) treatments. Our knockdown of BCL2L15 by specific shRNA that significantly hampered endometrial receptivity. In the absence of BCL2L15, the signal transducer and activator of transcription (STAT)1 and STAT3 pathway were activated. Additionally, pretreatment with the STAT1 inhibitor, fludarabine, restored the effect of silencing BCL2L15 on the endometrial receptivity, but not the STAT3 inhibitor Stattic.
