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).

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. 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 aim of the study was to assess the cellular composition and transcriptional changes at single-cell resolution of the female reproductive tract across the four stages of estrus cycle in young adult mice (ovary, oviduct, uterus, cervix and vagina, with spleen as a comparison) and compared this with similar analyses of decidualization (uterus) and ageing (ovary, oviduct, uterus, cervix, vagina and spleen). Vaginal smears were used to stage the estrus cycle in young mice. To collect the decidualized uteri mice were mated and uterine tissue was collected from pregnant mice at day 5.5 after mating. Tissues of aged mice were collected at the age of 18 months. All tissues were collected and digested using a collagenase and trypsin protocol to obtain single cell suspension. Libraries were prepared using the 10x scRNA-seq protocol.

Project description:To determine the global changes in hypothalamic gene expression that may occur at the time of female puberty in this species, animals were euthanized at three different stages, juvenile (25-days of age), early puberty (30-35 days of age) and on the day of the first proestrus (32-37 days of age). According to criteria previously established (Ojeda,S.R.; Urbanski,H.F. Puberty in the rat pp.363-409. The Physiology of Reproduction, 2nd Edition, Vol 2. Edited by Knobil,E.; Neill,J.D. Raven Press, 1994), 25-day-old animals are in the mid- juvenile phase of prepubertal development (JUV). At this time, the vagina is not yet patent and the uterine weight is 60Â mg or less, with no accumulation of intrauterine fluid. Older rats showing a closed vagina, accumulation of intrauterine fluid and an uterine weight less that 180 mg are considered to be in the early proestrous (EP) phase of puberty. Finally, rats still exhibiting a closed vagina, but showing a uterus ballooned with fluid and a uterine weight of at least 200Â mg are considered to be in late proestrus (LP), i.e., the phase of puberty when the first preovulatory surge of LHRH and gonadotropins takes place. The first ovulation occurs the following day. All animals were sacrificed between 1600-1700 h, and the medial basal hypothalamus (MBH) was immediately dissected, as previously described (Rogers,L.C.; Junier,M-P.; Farmer,S.R.; Ojeda,S.R. A sex-related difference in the developmental expression of class II -tubulin messenger RNA in rat hypothalamus. Mol.Cell.Neurosci., 2: 130-138, 1991) and stored in RNAlater according to manufacturerâs instructions. Experiment Overall Design: Affymetrix arrays were used to detect global changes in gene expression in the hypothalamus of normal sexual development of the female rat.

Project description:Hormonal fluctuations throughout the ovarian cycle contribute to femalesâ?? higher vulnerability to anxiety disorders when compared to males. Notably, such sex differences are controlled by regulation of genes in the medial prefrontal cortex (mPFC) including the transcription factor early growth response 1 (Egr1) in rats, which highlights a control of anxiety-like behaviors by sexually-biased gene expression. We therefore undertook a large-scale characterization of sex differences and their interaction with the estrous cycle in the adult mPFC transcriptome and report that proestrus and diestrus females (with high and low ovarian hormones levels, respectively) exhibited a partly-opposed sexually-biased transcriptome. Surprisingly, the extent of regulations within females vastly exceeded sex differences, and support a multi-level reorganization of synaptic function across the estrous cycle. Furthermore, genome-wide analysis of Egr1 binding highlighted its role in controlling the synapse-related genes varying within females, and the sex- and estrous cycle-dependent transcriptomic reorganization in the rat mPFC. Early growth response 1 (Egr1) binding profiling in the adult rat medial prefrontal cortex of males, proestrus females, and diestrus females. A total of 9 animals were used, corresponding to 3 Males, 2 proestrus females, and 4 diestrus females.

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.
