Project description:Background:The morphology of vaginal secretions during estrus and diestrus is characteristic and easy to distinguish. There are also significant differences in hormone levels between the two periods in physiological condition. However, the gene changes during estrus cycle especially the two periods are still unclear. Therefore, this study plans to find out the pathway changes related to the estrus cycle of female mice, the expression of various proteins, predict the genes sensitive to hormone changes in vivo through gene analysis of 15 tissues in the two periods and construct of differential gene expression library. Methods:The wildtype healthy female mice in estrus were compared with those in diestrus. The transcriptome changes between the two periods were probed by using high-throughput RNA-seq techniques. Results:A comprehensive mouse transcriptome map in estrus or diestrus across fifteen tissues including aorta, vein, brown adipose tissue, white adipose tissue, heart, kidney, liver, skeletal muscle, stomach, duodenum, cerebrum, hypothalamus, ovary, womb and spleen were provided. Conclusions:This dataset could serve as a baseline resource for investigating the potential gene changes sensitive to the estrus cycle across different tissues and provide the information for screening the key functional genes or molecular markers of estrus cycle.

Project description:The oviducts play a critical role in gamete and embryo transport, as well as supporting fertilization and early embryo development. Progesterone receptor (PGR) is a transcription factor highly expressed in oviductal cells, while it’s activating ligand, progesterone (P4), surges to peak levels as ovulation approaches. P4 is known to regulate oviduct cilia beating and muscular contractions in vitro, but how PGR may mediate this in vivo is poorly understood. We used PGR-knockout (PRKO) mice to determine how PGR regulates oviductal function during the periovulatory period, in particular oviductal transport and embryo support. We used microarrays to identify putative PGR-regulated genes in the oviduct during the periovulatory period, a time when the oviduct is preparing to receive the newly-ovulated COC. The mutant strain used in this experiment were PRlacZ knock-in mice which originated from Assoc Prof John Lydon, Baylor College of Medicine, Houston TX, USA. The lacZ insertion results in disruption of transcription of both isoforms of PGR (Ismail et al, 2002, Mol Endocrinol 16:2475-2489), and therefore mice homozygous for the lacZ insertion are a phenocopy of the knockout strain described by Lydon et al. (1995, Genes Dev. 9:2266-2278) and are hereafter referred to as PRKO. Heterozygous mice (PR+/-) are a phenocopy of WT and have normal fertility (Ismail et al, 2002) and are therefore appropriate controls. Whole oviducts were collected from pre-pubertal PRKO and PR+/- mice 8 h after a standard protocol for hormonal induction of ovulation. Day 21-23 old mice were injected i.p. with 5IU of equine chorionic gonadotropin (eCG) to stimulate follicle growth, followed 44-47 h later by i.p. injection of 5 IU of human chorionic gonadotropin (hCG) to trigger ovulatory processes. Oviducts from 15 animals were collected per genotype, with oviducts from 3 animals pooled per sample for a total of n = 5 samples per genotype.

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.

Project description:The effects of exogenous hormones used for estrus synchronization, and ovarian hyper stimulation on cumulus oocyte complexes (COCs) gene expression in sexually mature rats were determined using microarrays. Gene expression in COCs collected from GnRH (Gtrt), GnRH+eCG (G+Etrt), and GnRH+eCG+hCG (G+E+Htrt) treatments were compared to COCs from naturally cycling (NC) rats. There was no significant difference in gene expression among NC, Gtrt and G+Etrt. Over 2600 genes were significantly different between NC and G+E+Htrt (P<0.05). Genes encoding proteins that are involved in prostaglandin synthesis (Ptgs2, Pla2g4a, Runx1); cholesterol biosynthesis (Hmgcr, Sc4mol, Dhcr24); receptors that allow cholesterol uptake (Ldlr, Scarb1); regulate progesterone synthesis (Star); inactivate estrogen (Sult1e1); and downstream effectors of LH signal (Pgr, Cebpb, Creb3l1, Areg, Ereg, Adamts1) were upregulated in G+E+Htrt. Genes encoding proteins that are involved in DNA replication (Ccne2, Orc5l, Rad50, Mcm6); reproductive developmental process and granulosa cell expansion (Gdf9, Bmp15, Amh, Amhr2, Bmpr1b, Tgfb2, Foxl2, Pde3a, Esr2, Fshr, Ybx2, Ccnd2, Ccnb1ip1, Zp3); maternal effect genes that are important for embryo development (Zar1, Npm2, Nlrp5, Dnmt1, H1foo, Zfp57); amino acid degradation and ketogenesis (Hmgcs2 , Cpt1b) were downregulated in G+E+Htrt. These results on rat model show that hormones used for estrus synchronization (Gtrt) and ovarian hyper stimulation (G+Etrt) had minimal effects on gene expression. However, induction of ovulation (G+E+Htrt) caused major changes in gene expression of rat COCs. This study provides comprehensive information about regulated genes during late follicle development and ovulation induction. Four experimental groups were used and there were 6 animals in each group. Total of 24 arrays were used. Only raw data used in publication.

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.
