Non Technical Summary
Infertility, pregnancy loss and intrauterine growth retardation are common problems that affect reproductive efficiency, health and development in livestock as well as humans. A large percentage of these problems may be attributed to uterine dysfunction during the critical windows of pregnancy establishment and implantation. Collectively, results from the proposed studies should identify uterine factors affecting embryonic survival, conceptus development and fetal/placental growth. Knowledge gained from the proposed studies will be useful to design management, biotechnology and genetic applications aimed at enhancing production efficiency of animal agriculture.

Goals / Objectives
Long-term research goals are to: (1) determine the hormonal, cellular and molecular mechanisms regulating uterine development; (2) determine the role(s) of uterine glands in mammalian pregnancy; (3) identify and determine the cellular and molecular mechanisms regulating expression of genes in the uterine glands; and (4) identify and determine the physiological function(s) of genes expressed in the uterine glands during pregnancy. Accomplishment of these research goals should significantly advance our understanding of mammalian uterine function and provide new knowledge essential to solve reproductive problems that involve endometrial dysfunction, such as infertility, pregnancy loss and intrauterine growth retardation. Research in this proposal will utilize a novel uterine gland knockout (UGKO) ewe model to identify genes expressed in the endometrial glands and proteins present in the uterine lumen of the sheep uterus that affect the capacity of uterine endometrium to support conceptus survival and development. Many of the growth factors, cytokines and proteins produced by the endometrium of sheep are also found in the endometrium of other ruminants as well as humans. The central hypothesis is that substances secreted by the uterine glands are required for conceptus (embryo/fetus and associated placental membranes) survival and growth. In order to test this hypothesis, the differentiation of uterine glands has been epigenetically ablated in neonatal ewes, thereby creating a unique Uterine Gland Knock Out (UGKO) phenotype in adult ewes that does not exist in any other available mammalian model system. Available results from current research findings strongly support the central hypothesis that uterine glands are required for peri-implantation conceptus survival and growth in the ewe. Specific objectives of the research plan are to test the hypotheses that defects in conceptus survival and elongation in UGKO ewes are due to absence of: (1) specific genes encoding secretory proteins and molecular transporters expressed by the uterine glands; and (2) specific proteins and other biological active substances (amino acids, lipids, microvesicles, sugars, etc.) in the uterine lumen that are synthesized and secreted or transported by the endometrial glands.
Project Methods
OBJECTIVE ONE: Functional genomic analysis of endometrial GE gene expression utilizing the UGKO ewe model.Experiments in this objective will test the hypothesis that defects in conceptus survival and development in UGKO ewes are due to absence of specific genes encoding secretory proteins expressed by the uterine glands. The approach will be to use next generation sequencing analyses to profile and compare gene expression in endometrium from UGKO ewes on Day 14 post-mating with that in endometrium from Day 14 pregnant (Px) ewes and Day 14 non-Px control ewes. In addition, GE from endometrium of Day 14 Px ewes will be isolated by laser capture microdissection (LCM) and profiled by RNA sequencing analysis to ascertain which differentially expressed genes are specifically expressed by GE. (Please see the attached proposal for further details)OBJECTIVE TWO: Functional proteomic analysis of the uterine milieuExperiments in this objective will test the hypothesis that defects in conceptus survival and elongation in UGKO ewes are due to absence of specific proteins and other bioactive molecules produced or transported by the uterine glands into the uterine lumen. The approach is to analyze uterine flush proteins and other metabolites from Day 14 Px, non-Px and bred UGKO ewes using high throughput technologies. (Please see the attached proposal for further details)
