MiRNA regulatory networks in male and female mouse ESC-to-EpiSC differentiation [miRNA]

ABSTRACT: Early stem cell differentiation programmes are tightly controlled by coordinated pre- and post-transcriptional regulatory networks. In this study, we investigate and characterise miRNA networks responsible for the post-translational gene regulation in early differentiation in both female and male mouse embryonic stem cells. We obtained miRNA-Seq and RNA-Seq profiles of male and female cells from day 0 (D0; 2i) to days 4, 10, 20 and 30. Interestingly, we observed a significant difference in gene expression profiles between females and males, both in terms of identity of regulated genes and of temporal characteristics. Similarly, we observed differences between miRNA species playing significant regulatory roles in female and male cells.

miRNA expression in lung tissue

Project description:Sex differences in the incidence and prognosis of respiratory diseases have been reported. Studies have shown that women are at increased risk of adverse health outcomes from air pollution than men, but sex-specific immune gene expression patterns and regulatory networks have not been well studied in the lung. MicroRNAs (miRNAs) are environmentally sensitive posttranscriptional regulators of gene expression that may mediate the damaging effects of inhaled pollutants in the lung, by altering the expression of innate immunity molecules. Here, male and female mice of the C57/Bl6 background were exposed to 2ppm of ozone or filtered air (control) for 3 hours. Female mice were also exposed at different stages of the estrous cycle. Following exposure, lungs were harvested and total RNA was extracted. We used PCR arrays to study sex-differences in the expression of 84 miRNAs predicted to target inflammatory and immune genes. Our results identified differentially expressed miRNA signatures in the lungs of male vs. female exposed to ozone. In silico pathway analyses identified sex-specific biological networks affected by exposure to ozone that ranged from direct predicted gene targeting to complex interactions with multiple intermediates. We also identified differences in miRNA expression and predicted regulatory networks in females exposed to ozone at different estrous cycle stages. These results indicate that both sex and hormonal status can influence lung miRNA expression in response to ozone exposure, indicating that sex-specific miRNA regulation of inflammatory gene expression could mediate differential pollution-induced health outcomes in men and women.

Watanabe2018_State Transition Model with Treatment and Costs

Project description:Model with functions depending on Age, Male, BP (Blood Pressure). There are 3 disease states: Healthy, Sick, and Dead, where the Dead state is terminal. The yearly transition probabilities are: Healthy to Dead: Age/1000; Healthy to Sick: According to function F1 depending on Age and Male and BP; Sick to Healthy: 0.1; Sick to Dead: according to function F2 depending on Age and Male. Pre-Transition Rules: Age increased by 1 and BP by Age/10 each simulation cycle. Post-Transition Rules: Treatment = BP>140 , becomes 1 when BP crosses 140 threshold; BP =BP-Treatment*10 , meaning a drop of 10 once treatment is applied; CostThisYear = Age + \Treatment*10 , cost depends on age and if treatment was taken; Cost= Cost + CostThisYear , it accumulates cost over time. Initial conditions: Healthy = (50 Male, 50 Female with Age =1,2,...,50 for each individual), BP =120, Sick = (0,0) and Dead = (0,0). Output: Number of men and women in each disease state for years 1-10 and their ages and costs in each state. A stratified report by male and female and young – up to age 30 and old above age 30 is produced.

miRNA profiling in male and female chicken embryonic gonads during sexual differentiation

Project description:MicroRNAs (miRNAs) are a highly conserved class of small RNAs which function in a sequence-specific manner to post-transcriptionally regulate expression of target genes. Tissue-specific miRNA expression studies have discovered numerous functions for miRNAs in various aspects of embryonic development, but a role for miRNAs in gonadal development and sex differentiation has not yet been reported. Using the chicken embryo as a vertebrate model, differential miRNA expression between male and female embryonic gonads, was analysed at three developmental stages (embryonic days (E) 5.5, E6.5 and E9.5), using custom-designed 4x2K CombiMatrix miRNA microarray. The aims of this study were to: 1-identify miRNAs differentialy expressed by sex; 2-identify sex-specific miRNAs; 3-analyse global changes in miRNA up-regulation in male versus female gonads before, during and after the histological onset of sexual differentiation. This study provides a basis for establishing whetehr miRNAs are involved in either initiating or regulating vertebrate gonadal sex differentiation. Keywords: miRNA, sex comparison, developmental stage comparison. miRNA samples from male and female embryonic chicken gonads from three developmental stages: embryonic day (E) 5.5 (Hamilton & Hamburger (HH) stage 27-28), E6.5 (HH stage 29-30) & E9.5 (HH stage 35-36). Samples are listed with biological replicates used for analysis in brackets following: 1 - Male E5.5 (5); 2 - Female E5.5 (4); 3 - Male E6.5 (5); 4 - Female E6.5 (3); 5 - Male E9.5 (4); 6 - Female E9.5 (4).

Global gene expression profile of mouse ESC-2i, EpiSC-CHIR/XAV and EpiSC-FGF2/activin

Project description:The requirements for self-renewal differ between EpiSCs and ES cells and the underlying mechanism is largely unknown. Here we show that mouse EpiSCs can be efficiently derived and robustly propagated even from single cells, using two small-molecule inhibitors: CHIR99021 and XAV939. The whole-genome microarray analyses is performed to confirm the identity of EpiSC maintained in CHIR/XAV by comparing the expression profile in EpiSC-CHIR/XAV to those in ESC maintained in 2i and EpiSC maintained in FGF2/activin. Total RNA from ESC-2i, EpiSC-CHIR/XAV, and EpiSC-FGF2/activin were extracted for microarray analisys

Time-series of gene expression in female murine ES cells during EpiSC differentiation

Project description:Embryonic stem cells (ESC) are derived from the inner cell mass of the blastocyst in the presence of leukemia inhibitory factor (LIF). In vivo these cells then differentiate into epi stem cells (EpiSC) that can be derived from the Epiblast in presence of Fgf2 and ActivinA. In this study, female ESCs cultured in 2i medium have been differentiated into EpiSC for 3.5 days in vitro by addition of Fgf2 and Activin A. The gene expression profile was analyzed every 4-12 h using mouse exon arrays.

Peripheral Blood miRNA Transcriptomic Analysis for Salmonella Infection in Pig

Project description:Peripheral blood transcriptome is an important intermediate data source for investigation of the mechanism of Salmonella invasion, proliferation, and transmission but its development in pig is quite limited. We challenged four-week-old piglets (Duroc × Landrace × Yorkshire crossbred) with Salmonella enterica serovar Typhimurium LT2 and investigated the peripheral blood miRNA expression profile before treatment (d0) and at 2 days post inoculation (dpi) using deep sequencing technology.
