Reprod Fertil Dev 2019; 31:496-508. [PMID: 30253121 DOI: 10.1071/rd18144] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2018] [Accepted: 08/27/2018] [Indexed: 12/11/2022] Open
Abstract
Previous endometrial gene expression studies during the time of conceptus migration did not provide final conclusions on the mechanisms of maternal recognition of pregnancy (MRP) in the mare. This called for a cell type-specific endometrial gene expression analysis in response to embryo signals to improve the understanding of gene expression regulation in the context of MRP. Laser capture microdissection was used to collect luminal epithelium (LE), glandular epithelium and stroma from endometrial biopsies from Day 12 of pregnancy and Day 12 of the oestrous cycle. RNA sequencing (RNA-Seq) showed greater expression differences between cell types than between pregnant and cyclic states; differences between the pregnant and cyclic states were mainly found in LE. Comparison with a previous RNA-Seq dataset for whole biopsy samples revealed the specific origin of gene expression differences. Furthermore, genes specifically differentially expressed (DE) in one cell type were found that were not detectable as DE in biopsies. Overall, this study revealed spatial information about endometrial gene expression during the phase of initial MRP. The conceptus induced changes in the expression of genes involved in blood vessel development, specific spatial regulation of the immune system, growth factors, regulation of prostaglandin synthesis, transport prostaglandin receptors, specifically prostaglandin F receptor (PTGFR) in the context of prevention of luteolysis.

Proteomic analysis of sheep uterus reveals its role in prolificacy. J Proteomics 2019; 210:103526. [PMID: 31605788 DOI: 10.1016/j.jprot.2019.103526] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2019] [Revised: 08/19/2019] [Accepted: 09/04/2019] [Indexed: 12/23/2022]
Abstract
Small Tail Han sheep have attracted attention for their high fecundity and year-round estrus. However, the molecular mechanisms of this fecundity are unknown. Polymorphism of the FecB gene has been shown to be associated with the ovulation rate and litter size in sheep. In this study, we used tandem mass tag quantitative proteomic techniques to identify the differentially abundant proteins in polytocous and monotocous Small Tail Han sheep (FecB++) uterine tissues in the follicular and luteal phases. In total, 41 and 43 differentially abundant proteins were identified in the follicular and luteal phases, respectively. Correlation analysis between the transcriptome and proteome revealed a positive correlation at the two omics levels of prolificacy. GO and KEGG pathway analyses indicated that the mRNAs and proteins upregulated in the polytocous group relative to the monotocous group are involved in sphingolipid metabolism and amino acid metabolism, and may be important in maintaining uterine functions and increasing the embryo survival rate during the estrus cycle of polytocous sheep. In conclusion, our work provides a prospective understanding of the molecular mechanism underlying the high prolificacy of Small Tail Han sheep. SIGNIFICANCE: Fecundity critically affects the profitability of sheep production, but the genetic mechanism of high-prolificacy is still unclear in sheep. We identified potential signaling pathways and differentially abundant proteins associated with reproductive performance through a combination of sheep uterus tissues proteome and transcriptome analyses. These findings will facilitate a better revealing the mechanism and provide possible targets for molecular design breeding for the formation of polytocous traits in sheep.

Jang H. Regulation of Cyclic AMP-Response Element Binding Protein Zhangfei (CREBZF) Expression by Estrogen in Mouse Uterus. Dev Reprod 2018; 22:95-104. [PMID: 29707688 PMCID: PMC5915772 DOI: 10.12717/dr.2018.22.1.095] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2018] [Revised: 03/11/2018] [Accepted: 03/24/2018] [Indexed: 12/29/2022]
Abstract
CREBZF (cAMP-response element binding protein zhangfei) is a member of ATF/CREB
family, and which regulates various cellular functions by suppressing major
factors with direct interaction. In this study, we have examined the expression
of CREBZF on mouse endometrium during uterus estrous cycles and estrogen (E2)
treatment. In uterus, CREBZF mRNA expression was higher than
other organs and mRNA and protein of CREBZF was increased in proestrus phase and
decreased in estrus phase. The expression of CREBZF in 3-weeks old mouse uterus
was reduced by E2 injection in endometrium. In addition, the expression of
progesterone receptor, a marker of E2 in ovariectomized mice was found to be
strongly expressed in stroma, while CREBZF was only expressed in epithelium.
Also, we conformed that E2-suppressed CREBZF was restored by co-injection of ICI
182,780, an estrogen receptor antagonist. Overall, these results suggest that
CREBZF is regulated by estrogen and involved in ER signaling pathway in mouse
uterus.

Rapid expression of RASD1 is regulated by estrogen receptor-dependent intracellular signaling pathway in the mouse uterus. Mol Cell Endocrinol 2017; 446:32-39. [PMID: 28188843 DOI: 10.1016/j.mce.2017.02.006] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2016] [Revised: 02/03/2017] [Accepted: 02/05/2017] [Indexed: 11/30/2022]
Abstract
Dexamethasone-induced RAS-related protein 1 (RASD1) is a signaling protein that is involved in various cellular processes. In a previous study, we found that RASD1 expression was down-regulated in the uterine endometrium of repeated implantation failure patients. The study aim was to determine whether RASD1 is expressed in the endometrium of mouse uterus and how it is regulated by steroid hormones during the estrous cycle. In this study, we investigated RASD1 expression and regulation in an ovariectomized female mouse model. Rasd1 mRNA was highly expressed in mouse reproductive tissues, including the uterus. Rasd1 expression was detected exclusively in the endometrial epithelium at the proestrus stage of the estrous cycle. Rasd1 expression in uteri increased with administration of estradiol, but not progesterone. Its expression was rapidly induced within 2 h after E2 treatment. Pretreatment with ICI 182,780, an estrogen receptor antagonist, reduced RASD1 protein expression. In addition, we identified that rapid expression of Rasd1 was mediated by the estrogen intracellular signaling including both p38-mitogen-activated protein kinase and the extracellular signal-regulated kinase. These findings suggest that RASD1 acts as a novel signaling molecule and plays an important role in regulating dynamic uterine remodeling during the estrous cycle in the uterus.
