Published in 2017 at "Molecular Reproduction and Development"

DOI: 10.1002/mrd.22835

Abstract: Porcine conceptuses secrete pregnancy‐recognition signals (estrogens, including estradiol‐17β) that inhibit luteolysis, thereby prolonging progesterone production by corpora lutea. The supportive mechanism by which the conceptus also inhibits luteolysis is by shifting endometrial prostaglandin (PG) synthesis… read more here.

DOI: 10.1016/j.placenta.2018.06.308

Abstract: INTRODUCTION Glucose is the primary energy substrate for early conceptus development and, for the first 40 days of gestation, the equine conceptus depends solely on glucose available in the histotroph; thereafter, histotrophic glucose provision continues… read more here.

DOI: 10.1016/j.theriogenology.2016.11.033

Abstract: Maternal recognition of pregnancy (MRP) and implantation involve appropriate interactions between the elongating conceptus and the receptive endometrium that will condition development of the feto-placental unit to term. Molecular mechanisms that take place at the… read more here.

Published in 2017 at "Scientific Reports"

DOI: 10.1038/srep40476

Abstract: Exosomes and microvesicles are extracellular vesicles released from cells and can contain lipids, miRNAs and proteins that affect cells at distant sites. Recently, microvesicles containing miRNA have been implicated in uterine microenvironment of pigs, a… read more here.

Published in 2021 at "Biology of reproduction"

DOI: 10.1093/biolre/ioab186

Abstract: Establishment and maintenance of pregnancy in the pig is a complex process that relies on conceptus regulation of the maternal proinflammatory response to endometrial attachment. Following elongation, pig conceptuses secrete interferon gamma (IFNG) during attachment… read more here.

Published in 2022 at "Biology of reproduction"

DOI: 10.1093/biolre/ioac039

Abstract: Among the many calcium-binding proteins, S100A8, S100A9, and S100A12 play important roles in inflammation, innate immunity, and antimicrobial function, but their expression, regulation, and function at the maternal-conceptus interface in pigs are not fully understood.… read more here.

Published in 2024 at "Biology of Reproduction"

DOI: 10.1093/biolre/ioae044

Abstract: Abstract Interferon-gamma (IFNG) is a pro-inflammatory cytokine secreted by the porcine conceptus (embryo and extra-embryonic membranes) during the peri-implantation period of pregnancy. IFNG modifies the endometrial inflammatory immune response and is required for the implantation… read more here.

Published in 2024 at "Biology of Reproduction"

DOI: 10.1093/biolre/ioae088

Abstract: Abstract In pigs, the majority of embryonic mortality occurs when free-floating conceptuses (embryos/fetuses and associated placental membranes) elongate, and the uterine–placental interface undergoes folding and develops areolae. Both periods involve proliferation, migration, and changes in… read more here.

DOI: 10.1093/biolre/ioaf077

Abstract: Abstract Early embryo loss affects all mammalian species, including humans, and agriculturally important food-producing mammals such as cattle. The developing conceptus (embryo and extraembryonic membranes) secretes proteins that can modify the endometrium and can be… read more here.

DOI: 10.1093/jas/skac137

Abstract: Widespread regions of the southeast United States have soils, and hence forages, deficient in selenium (Se), necessitating Se supplementation to grazing cattle for optimal immune function, growth, and fertility. We have reported that supplementation with… read more here.
