Project description:The potential for xenoestrogens and other environmental chemicals to alter female reproductive function calls for the study of their affects on endogenous hormone-regulated gene expression pathways during uterine tissue remodeling which occurs as part of the menstrual/estrus cycle. However, our knowledge of these pathways is limited. Here, we characterize changes in the CD-1 mouse uterine luminal epithelial cell transcriptome during proestrus and estrus, which are regulated by estrogen and progesterone in preparation of the uterus for pregnancy. Mice were staged beginning at 6 wk of age and uterine horns were harvested at estrus and proestrus. RNA was extracted from lumenal epithelium of uterine horns. Microarray analysis identified 2,251 genes differentially expressed in estrus compared to proestrus in lumenal epithelial cells. These complement other studies where RNA was extracted from whole uterine horns of mice in estrus and proestrus (GSE43064).

Beginning on postnatal day 41, female CD-1 mice were monitored for reproductive stage cycle and total RNA was isolated from lumenal epithelium of uterine horns at estrus or proestrus. Tissue was collected on postnatal days 41-61. Samples were pooled for microarray analysis as follows. Seven litters were used to generate 2 tissue pools for estrus and 2 tissue pools for proestrus. Each pool was comprised of uterine tissue RNA from n=4-5 individual mice and n=3-4 individual litters. Fluorescent labeling of RNA and hybridization of the Alexa 555-labeled (green) and Alexa 647-labeled (red) RNA samples to Agilent-026655 Whole Mouse Genome Microarray 4x44K v2 (Agilent Technology, Palo Alto, CA; catalog # G4846A) were carried out, with dye swapping for each estrus cycle stage comparison.

Project description:The potential for xenoestrogens and other environmental chemicals to alter female reproductive function calls for the study of their affects on endogenous hormone-regulated gene expression pathways during uterine tissue remodeling which occurs as part of the menstrual/estrus cycle. However, our knowledge of these pathways is limited. Here, we characterize changes in the CD-1 mouse uterine transcriptome during proestrus and estrus, which are regulated by estrogen and progesterone in preparation of the uterus for pregnancy. Mice were staged beginning at 6 wk of age and uterine horns were harvested after monitoring two estrus cycles. Microarray analysis identified 2,429 genes differentially expressed in estrus compared to proestrus, indicating that the mouse uterus undergoes remarkable remodeling during the estrus cycle, affecting ~10% of all protein-coding genes. Changes in gene expression associated with structural alteration of the uterus include remodeling of the extracellular matrix, changes in cell keratins and adhesion molecules, activation of mitosis, MHC class II presentation, complement and coagulation cascades, and cytochrome P450 expression. Signaling pathways regulated during the estrus cycle, involving ligand-gated channels, Wnt and hedgehog signaling, and several transcription factors with poorly understood roles in reproductive tissues, include several genes and gene networks that have been implicated in pathological states. The information presented here builds a background for understanding of mechanisms involved in uterine tissue response to endocrine disruptors and the development of reproductive tract diseases. Beginning on postnatal day 42, female CD-1 mice were monitored for reproductive stage cycle for 2 consecutive cycles and then total RNA was isolated from uterine horns at estrus or proestrus. Samples were pooled for microarray as follows. Six litters were used to generate 2 tissue pools for estrus and 2 tissue pools for proestrus, with estrus pool 1 and proestrus pool 1 comprised of mice from the same 3 litters, and estrus pool 2 and proestrus pool 2 comprised of mice from the other 3 litters. Each pool was comprised of uterine tissue RNA from n= 4-6 individual mice.

Project description:Hormone dependent uterine gene expression changes that occur during the estrous cycle suggest hormone receptor binding to chromatin may also be dynamic. Therefore, we employed a multi-faceted approach to examine in vivo dynamics of hormone receptor occupancy, chromatin accessibility and chromatin structure by combining RNA-seq, ATAC-seq, HiC-seq and ChIP-seq for estrogen receptor alpha (ERα) and progesterone receptor (PGR). Genome wide, there were extensive estrous cycle dependent changes in ERα and PGR binding as well as chromatin accessibility. There were 4,159 differentially expressed genes between estrus and diestrus. At transcription start sites, accessibility generally correlated with the directionality of gene expression and there was reduced PGR in estrus compared to diestrus but little change in ERα. There were 2,727 enhancers with dynamic accessibility near these genes and 77% of those correlated with directionality of gene expression changes. However, most enhancers were constitutively open (8,694). In both dynamic and constitutively open enhancers, ERα and PgR binding was coordinately lost from diestrus to estrus. Diestrus specific ERα binding and accessible regions were enriched for PGR, FOX, GATA and SOX binding motifs. In contrast, estrus specific ERα binding occurred at transcription factor deserts in relatively closed chromatin while estrus specific accessible regions were highly enriched for ATF, ELF and ELK motifs. Rapid Immunoprecipitation Mass spectrometry of Endogenous proteins (RIME) revealed many estrous cycle dependent partners of ERα (diestrus, 60; estrus, 24). PGR was found in complex with ERα during diestrus but not estrus supporting coordinated binding of both receptors during diestrus. Two of the cohesin complex proteins, SMC1A and SMC3, were found in complex with ERα during diestrus but not estrus; overlap of SMC1A with ERα confirmed this preferential interaction during diestrus. Additionally, HiC analysis showed more diestrus specific interactions than estrus (476 versus 263) suggesting the SMC1A/ ERα interactions have functional consequences on chromatin structure. Taken together, a complex series of interactions between hormone receptors, chromatin structure and accessibility orchestrate estrous cycle dependent changes in gene expression.

Project description:The emergence of fully antimicrobial resistant Neisseria gonorrhoeae has led global public health agencies to identify a critical need for next generation anti-gonococcal pharmaceuticals. The development and success of these compounds will rely upon valid pre-clinical models of gonorrhoeae infection. We recently developed and reported the first model of upper genital tract gonococcal infection. During initial characterization, we observed significant reproductive cycle-based variation in infection outcome. When uterine infection occurred in the diestrus phase, there was significantly greater pathology than during estrus phase. The aim of this study was to evaluate transcriptional profiles of infected uterine tissue from mice in either estrus or diestrus phase in order to elucidate possible mechanisms for these differences. Genes and biological pathways with phase-independent induction during infection showed a chemokine dominant cytokine response to Neisseria gonorrhoeae. Despite general induction being phase-independent, this common anti-gonococcal response demonstrated greater induction during diestrus phase infection. Greater activity of granulocyte adhesion and diapedesis regulators during diestrus infection, particularly in chemokines and diapedesis regulators, was also shown. In addition to a greater induction of the common anti-gonococcal response, Gene Set Enrichment Analysis (GSEA) identified a diestrus-specific induction of type-1 interferon signaling pathways. This transcriptional analysis of murine uterine gonococcal infection during distinct points in the natural reproductive cycle provided evidence for a common anti-gonococcal response characterized by significant induction of granulocyte chemokine expression and high proinflammatory mediators. The basic biology of this host response to N. gonorrhoeae in estrus and diestrus is similar at the pathway level, but varies drastically in magnitude. Overlaying this, we observed type-1 interferon induction specifically in diestrus infection where greater pathology is observed. This supports recent work suggesting this pathway has a significant, possibly host-detrimental, function in gonococcal infection. Together these findings lay the groundwork for further examination of the role of interferons in gonococcal infection. Additionally, this work enables the implementation of the diestrus uterine infection model using the newly characterized host response as a marker of pathology and its prevention as a correlate of candidate vaccine efficacy and ability to protect against the devastating consequences of N. gonorrhoeae-associated sequelae. Murine microarrays were used to examine transcriptional differences underlying significantly different phenotypes associated with uterine N. gonorrhoeae infection in the estrus versus diestrus phases of the natural reproductive cycle.
