Project description:The uterus, a female reproductive organ regulated by the sex hormones estrogen and progesterone, undergoes periodic cyclical changes. The estrous cycle refers to the reproductive cycle in non-primate mammalian females. During the mouse estrous cycle, the uterus undergoes various physiological changes as a result of dynamic hormonal changes. Accurate regulation of these changes is crucial for the establishment of a successful pregnancy. Notably, estrogen plays an important role in the regulation of the proestrus and estrus stages of the estrous cycle. Family with sequence similarity 3 (Fam3) is a cytokine-like gene family with four members: Fam3a, Fam3b, Fam3c, and Fam3d. Expression and regulation of the Fam3 family members in mouse uterine physiology remain largely unknown. Therefore, this study aimed to investigate the expression of Fam family members in the uterus during the estrous cycle and evaluate its regulation by estrogen using a mouse model. Analysis of mouse uterine RNA sequencing data revealed upregulated expression of Fam3b, Fam3c, and Fam3d during the proestrus and estrus stages. Fam3d expression was dynamically regulated during the estrous cycle, with high expression levels during the proestrus and estrus stages. To investigate whether Fam3d expression is regulated by estrogen, we administered estradiol (E2) to ovariectomized mice at different time points. Fam3d expression was highest 24 h after E2 injection, suggesting that estrogen plays a crucial role in regulating Fam3d expression. Furthermore, inhibition experiments using the estrogen receptor alpha (ERα) antagonist ICI revealed that estrogen regulates Fam3d expression through the ERα-mediated pathway. Immunofluorescence staining demonstrated that FAM3D was exclusively expressed in the luminal and glandular epithelia but not in the stroma. Additionally, FAM3D was predominantly localized in the cytoplasm, particularly in the apical region, and not in the nucleus. These findings provide valuable insights into the potential role of Fam3d in the uterus and lay the groundwork for future research on its function and significance in uterine physiology.

Project description:The adult uterus regenerates in the human during the menstrual cycle, and remodels in the mouse during the estrous cycle. Decades of work has demonstrated that this process is controlled by cycling steroid hormones, estrogen and progesterone. However, downstream signaling pathways that link hormonal action to this regeneration and remodeling are yet to be identified in the cycling uterus. We set out to identify these pathways, with the overarching hypothesis that developmental signaling pathways are redeployed in the adult uterus to control remodeling in the mouse.

Project description:We analyzed the transcriptome of the C57BL/6J mouse hypothalamus, hippocampus, neocortex, and cerebellum to determine estrous cycle-specific changes in these four brain regions. We found almost 16,000 genes are present in one or more of the brain areas but only 210 genes, ~1.3%, are significantly changed as a result of the estrous cycle. The hippocampus has the largest number of differentially expressed genes (DEGs) (82), followed by the neocortex (76), hypothalamus (63), and cerebellum (26). Most of these DEGs (186/210) are differentially expressed in only one of the four brain regions. A key finding is the unique expression pattern of growth hormone (Gh) and prolactin (Prl). Gh and Prl are the only DEGs to be expressed during only one stage of the estrous cycle (metestrus). To gain insight into the function of the DEGs, we examined gene ontology and phenotype enrichment and found significant enrichment for genes associated with myelination, hormone stimulus, and abnormal hormone levels. Additionally, 61 of the 210 DEGs are known to change in response to estrogen in the brain. 50 genes differentially expressed as a result of the estrous cycle are related to myelin and oligodendrocytes and 12 of the 63 DEGs in the hypothalamus are oligodendrocyte- and myelin-specific genes. This transcriptomic analysis reveals that gene expression in the female mouse brain is remarkably stable during the estrous cycle and demonstrates that the genes that do fluctuate are functionally related.

Project description:Saliva is considered as the best source for biomarker-discovery studies, since it is a non-invasive method when compared to other body sources. Usually, buffalo cannot express their estrus signs precisely. Hence, there is a need for concise methods to detect the time of estrus to ensure the success in artificial insemination. Therefore, we have established a reference proteome map on buffalo whole saliva during estrous cycle in order to document the estrus-specific proteins using SDS-PAGE and mass spectrometry. The present findings conclude that the proteomic approach adopted to identify the proteins from buffalo saliva around estrous cycle may provide a new tool for screening the estrus phase.

Project description:Males and females often differ on propensity for a substance use disorder (SUD), etiology and clinical manifestation of SUD, and response to SUD treatment strategies (Riley et al 2018). The fluctuation of sex-related hormones in the brain and/or circulation may contribute to some of these differences. For example, estradiol activity has been associated with sensitivity to drugs of abuse (Tonn Eisinger et al 2018) and vulnerability to SUD (Anker and Carroll 2011). In particular, estrogen can affect the dopamine system in brain and this may contribute to differences in the etiology and the clinical manifestation of SUD (Bobzean et al 2014). Without direct association with SUD, others have shown that stage of the estrous cycle influences RNA transcription levels and splicing in particular brain regions (Duclot and Kabbaj 2015; DiCarlo et al 2017). What has not been thoroughly explored is whether genetic factors can modify the effect of estrous cycle on RNA transcript and ultimately, whether the interaction of these two factors can influence the sex-related differences in SUD vulnerability.

Project description:Cluster of differentiation 73 (CD73, also known as ecto-5'-nucleotidase) is an enzyme that converts AMP into adenosine. CD73 is a surface enzyme bound to the outside of the plasma membrane expressed in several cells and regulates immunity and inflammation. In particular, it is known to inhibit T cell-mediated immune responses. However, the regulation of CD73 expression by hormones in the uterus is not yet clearly known. In this study, we investigated the expression of CD73 in ovariectomized mice treated with estrogen or progesterone and its regulation in the mouse uterus during the estrous cycle. The level of CD73 expression was dynamically regulated in the uterus during the estrous cycle. CD73 protein expression was high in proestrus, estrus, and diestrus, whereas it was relatively low in the metestrus stage. Immunofluorescence revealed that CD73 was predominantly expressed in the cytoplasm of the luminal and glandular epithelium and the stroma of the endometrium. The expression of CD73 in ovariectomized mice was gradually increased by progesterone treatment. However, estrogen injection did not affect its expression. Moreover, CD73 expression was increased when estrogen and progesterone were co-administered and was inhibited by the pretreatment of the progesterone receptor antagonist RU486. These findings suggest that the expression of CD73 is dynamically regulated by estrogen and progesterone in the uterine environment, and that there may be a synergistic effect of estrogen and progesterone.

Project description:The success of the early reproductive events depends on an appropriate communication between gametes/embryos and the oviduct. Extracellular vesicles (EVs) contained in oviductal secretions have been suggested as new players in mediating this crucial cross-talk by transferring their cargo (e.g. proteins, mRNA and small ncRNA) from cell to cell. Therefore, the objective of the project was to analyze the protein content of EVs (exosomes and microvesicles) contained in the bovine oviductal fluid at different stages of the estrus cycle. For this purpose, pairs of oviducts with their attached ovaries were collected from cyclic cows at a local abattoir under different hormonal regulation along the estrous cycle. Oviducts were classified into one of the 4 stages of the estrous cycle according to the morphology of the corpus lutea(CL) and follicle populations: Stage 1 (S1): showed recently ovulated follicle (d 1 to 4 of estrous cycle); Stage 2 (S2): early luteal development with medium or large or both present (d 5 to 11); Stage 3 (S3): fully functional CL yellow or orange in color (d 11 to 17); or Stage 4 (S4): regressing CL with little vasculature and a large preovulatory follicle present (d 18 to 20). EVs were collected by ultracentrifugation and prepared for mass spectrometry analysis.

Project description:The equine endometrium exhibits characteristic morphological and functional changes during the estrous cycle controlled by the interplay of progesterone and estradiol. A microarray analysis of endometrial tissue samples derived from 5 time points of the estrous cycle (D0, D3, D8, D12, and D16) was performed to study the dynamics of endometrial gene expression. Endometrial biopsies were collected from five mares (Bavarian Warmblood) at the respective time points. Samples were divided and subjected to isolation of RNA for microarray analysis and analysis of tissue composition. Blood samples were collected to determine serum progesterone levels for every sample. Statistical analysis of microarray data revealed almost 10,000 differential probes corresponding to 4,996 differentially expressed genes. A cluster analysis based on gene expression profiles during the estrous cycle revealed 8 major gene expression profiles: mRNAs with highest levels 1) at D0, 2) from D0 to D3, 3) at D3, 4) from D3 to D8, 5) at D8, 6) from D8 to D12, 7) from D12 to D16, and 8) at D16. DAVID Functional Annotation Clustering revealed overrepresentation of distinct functional terms in different phases of the cycle, e.g. M-bM-^@M-^Xextracellular matrixM-bM-^@M-^Y and M-bM-^@M-^Xprotein transportM-bM-^@M-^Y during estrus, M-bM-^@M-^XDNA replication and M-bM-^@M-^Xcell cycleM-bM-^@M-^Y during early luteal phase, M-bM-^@M-^Xendoplasmic reticulumM-bM-^@M-^Y and M-bM-^@M-^Xprotein transportM-bM-^@M-^Y in the luteal phase, and M-bM-^@M-^Xinflammatory responseM-bM-^@M-^Y in the late luteal and follicular phase. Expression of selected genes of the expression clusters was validated by quantitative Real-time PCR (qPCR). This study provides new insights into global changes of equine endometrial gene expression during the estrous cycle. Equine endometrial tissue samples were collected at 5 time points during the sexual (estrous) cycle from 5 mares (5 biological replicates per time point) and analyzed with Agilent microarrays.
