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: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:Despite buffaloes being primary farm animals, their reproductive performance remains poor mainly due to inaccurate estrus detection methods that ultimately has an economic impact on dairy industry as well as farmers. Recently, numerous studies showed potential of miRNAs as estrus biomarker. However, a miRNA profile of buffalo cell free saliva, a non-invasive fluid, at estrus and diestrus stages is missing. Hence, the present study was planned to identify differential levels of salivary cell free miRNAs in estrus as compared to the diestrus phase of buffalo oestrous cycle (n=3) in order to discover a possible estrus specific miRNAs as biomarkers. miRNA-Seq data analysis showed that in total 10 miRNAs i.e bta-miR-375, bta-miR-200c, bta-miR-30d, bta-let-7f, bta-miR-200a, bta-miR-12034, bta-let-7b, bta-miR-142-5p, bta-miR-2467-3p, bta-miR-30a-5p are significantly altered (log2foldchange >3 and p<0.05) during estrus in comparison to the diestrus phase in buffaloes, suggesting their estrus biomarker potential. Overall, 8 miRNAs i.e bta-miR-375 (6.87 Fold; p-value 0.003), bta-miR-200c (5.98 Fold; p-value 0.003), bta-miR-30d (4.17 Fold; p-value 0.015), bta-let-7f (3.34 Fold; p-value 0.022), bta-miR-200a (4.92 Fold; p-value 0.024), bta-miR-12034 (3.58 Fold; p-value 0.0025), bta-let-7b (3.06 Fold; p-value 0.031), bta-miR-30a-5p (4.7 Fold; p-value 0.036) were upregulated, whereas bta-miR-142-5p (-3.4 Fold; p-value 0.032) and bta-miR-2467-3p (-5.24 Fold; p-value 0.035) were downregulated during estrus. However, further validation study using qPCR is required in a large sample size in order to determine their estrus biomarker potential. In summary, our results revealed differential salivary cell free miRNAs profile during the oestrous cycle that may lead to the development of estrus specific miRNAs based point-of-care test applicable for the reproductive management of buffaloes in the field condition in the near future.
