Ablation of conceptus PTGS2 provides a new understanding of early pregnancy events in the pig
(University of Missouri--Columbia, 2019)Pig conceptuses produce and secrete estrogens (E[2]), interleukin 1 beta 2 (IL1B2), and prostaglandins (PGs) during the period of rapid trophoblast elongation and establishment of pregnancy. Previous studies established ... -
Characterization of interleukin-1 beta 2, a novel interleukin-1 expressed by the early pig conceptus during establishment of pregnancy
(University of Missouri--Columbia, 2014)It is essential that the early mammalian embryo attaches to the uterus or implants to survive. Most embryonic mortality is associated with complications during this process resulting in a loss of 25-60% of embryos or ... -
Effect of RU486, a progesterone antagonist, on uterine progesterone receptor, embryonic development and ovarian function during early pregnancy in pigs
(University of Missouri--Columbia, 2009)Progesterone (P4) down-regulates the progesterone receptor (PGR) exclusively within the epithelium of the pig uterus near d 8 of the estrous cycle and pregnancy. How P4 down-regulates the PGR is not understood but is ... -
New perspective on the role of conceptus estrogens in conceptus development, maternal recognition, and the establishment of pregnancy in pigs.
(University of Missouri--Columbia, 2018)The proposed signal for maternal recognition of pregnancy in pigs is estrogen, produced by the elongating conceptus. To understand the role of estrogen in porcine conceptus elongation and pregnancy establishment, a loss ...
