Description
Airway epithelial cells and macrophages differ markedly in their responses to influenza A virus (IAV) infection. To investigate transcriptional responses underlying these differences, purified subsets of type II airway epithelial cells (ATII) and alveolar macrophages (AM) recovered from the lungs of mock- or IAV-infected mice were subjected to RNA sequencing. In the absence of infection, AM predominantly expressed genes related to immunity whereas ATII expressed genes consistent with their physiological roles in the lung. Following IAV infection, AM almost exclusively activated cell-intrinsic antiviral pathways that were dependent on interferon regulatory factor (IRF)3/7 and/or type I interferon (IFN) signaling. In contrast, IAV-infected ATII activated a broader range of physiological responses, including cell-intrinsic antiviral pathways, which were both independent and dependent on IRF3/7 and/or type I IFN. These data suggest that transcriptional profiles hardwired during development could be a major determinant underlying the different responses of ATII and AM to IAV infection. Overall design: 96 samples were analyzed: (A) 4 replicates of HA+ Alveolar Macrophage (AM) and 4 replicates of CD103+ Dendritic cells (DC) isolated from the lung lobes of C57/BL6 mice on 9 h p.i. with PR8. 4 replicates of mock-infected (HA-) AM and 4 replicates of mock-infected (HA-) CD103+ DC isolated from the lung lobes of mock-infected C57/BL6 mice on 9 h p.i. with allantoic fluid of equal dilution as PR8. 4 replicates of HA+ Airway epithelial cell Type II (ATII) and 4 replicates of HA+ Ciliated Cell (CC) isolated from the lung lobes of C57/BL6 mice on 9 h p.i. with PR8. 4 replicates of mock-infected (HA-) ATII and 4 replicates of mock-infected (HA-) CC isolated from the lung lobes of mock-infected C57/BL6 mice on 9 h p.i. with allantoic fluid of equal dilution as PR8.

Description
Polycomb Repressive Complex 2 (PRC2) has been shown to play a key role in hematopoietic stem and progenitor cell (HSPC) function. Analyses of mouse mutants harboring deletions of core components have implicated PRC2 in fine-tuning multiple pathways that instruct HSPC behavior, yet how PRC2 is targeted to specific genomic loci within HSPCs remains unknown. Here we use shRNA-mediated knockdown to survey the function of known PRC2 accessory factors in HSPCs by testing the competitive reconstitution capacity of transduced murine fetal liver cells. We find that similar to the phenotype observed upon depletion of core subunit Suz12, depleting Jarid2 enhances the competitive transplantation capacity of both fetal and adult, mouse and human HSPCs. Gene expression profiling revealed common Suz12 and Jarid2 target genes that are enriched for the H3K27me3 mark established by PRC2. These data implicate Jarid2 as an important component of PRC2 that has a central role in coordinating HSPC function. Overall design: RNA-seq of jarid knockdown, suz knockdown and control from HSPC in 16 week old mice.

Description
This study relates to pregnancy outcome after assisted reproduction of fertility-classified cattle. The aim is to investigate how the uterine environment impacts and programs conceptus survival and development. The study found that ripple effects of dysregulated conceptus-endometrial interactions elicit post-elongation pregnancy loss in subfertile animals during the implantation period. Overall design: Heifer cows classified as high fertile (HF), subfertile (SF), or infertile (IF) were investigated. The RNA-seq analysis was performed for endometrium samples at day 17 of pregnancy. For comparison, non-pregnant cows were included in the analysis. RNA from conceptus of HF and SF pregnant animals (day 17) were also included in the RNA-seq analysis. A total of 25 endometrium samples (5 non-pregnant of each fertilty group, 5 pregnant HF, and 5 pregnant SF) and 27 conceptus samples (10 SF and 17 HF) were used in the RNA-seq analysis.

Description
Recent studies have been successful at utilizing ectopic expression of transcription factors to generate induced cardiomyocytes (iCMs) from fibroblasts, albeit at a low frequency in vitro. This work investigates the influence of small molecules that have been previously reported to improve differentiation to cardiomyocytes as well as reprogramming to iPSCs in conjunction with ectopic expression of the transcription factors Hand2, Nkx2.5, Gata4, Mef2C, and Tbx5 on the conversion to functional iCMs. We utilized a reporter system in which the calcium indicator GCaMP is driven by the cardiac Troponin T promoter to quantify iCM yield. The TGF inhibitor, SB431542 (SB), was identified as a small molecule capable of increasing the conversion of both mouse embryonic fibroblasts and adult cardiac fibroblasts to iCMs up to ~5 fold. Further characterization revealed that inhibition of TGF by SB early in the reprogramming process led to the greatest increase in conversion of fibroblasts to iCMs in a dose-responsive manner. Global transcriptional analysis at Day 3 post-induction of the transcription factors revealed an increased expression of genes associated with the development of cardiac muscle in the presence of SB compared to the vehicle control. Incorporation of SB in the reprogramming process increases the efficiency of iCM generation, one of the major goals necessary to enable the use of iCMs for discovery-based applications and for the clinic.

Description
Cardiac disease accounts for the largest proportion of adult mortality and morbidity in the industrialized world. However, progress toward improved clinical treatments is hampered by an incomplete understanding of the genetic programs controlling early cardiogenesis. To better understand this process, we set out to identify genes whose expression is enriched within early cardiac fated populations, obtaining the transcriptional signatures of mouse embryonic stem cells (mESCs) differentiating along a cardiac path.

Description
In mammals, a key transition in spermatogenesis is the exit from spermatogonial differentiation and mitotic proliferation and the entry into spermatocyte differentiation and meiosis. Although several genes that regulate this transition have been identified, how it is controlled and coordinated remains poorly understood. Here we examine the role in male gametogenesis of the Doublesex-related gene Dmrt6 (Dmrtb1) and find that Dmrt6 plays a critical role in directing germ cells through the mitotic to meiotic germ cell transition. DMRT6 protein is expressed in late mitotic spermatogonia. In mice of the C57BL/6J strain a null mutation in Dmrt6 disrupts spermatogonial differentiation, causing expression in inappropriate cell types of spermatogonial differentiation factors including SOHLH1, SOHLH2 and DMRT1 and the meiotic initiation factor STRA8 and causing most late spermatogonia to undergo apoptosis. In mice of the 129Sv background, most Dmrt6 mutant spermatogonia can complete differentiation and enter meiosis, but they show defects in chromosome pairing, establishment of the XY body, and processing of recombination foci, and mainly arrest in mid-pachynema. mRNA profiling of Dmrt6 mutant testes together with DMRT6 ChIP-seq suggest that DMRT6 represses genes involved in spermatogonial differentiation and activates genes required for meiotic prophase. Our results indicate that Dmrt6 plays a key role in coordinating the transition in gametogenic programs from spermatogonial differentiation and mitosis to spermatocyte development and meiosis. Overall design: Six samples for RNA-Seq with three biological replicates in each group. Two samples for ChIP-Seq (one input and one ChIP).

Description
Mouse embryonic stem cells can differentiate in vitro into spontaneously contracting cardiomyocytes. The main objective of this study was to investigate cardiogenesis in cultures of differentiating embryonic stem cells (ESCs) and to determine how closely it mimics in vivo cardiac development. We identified and isolated a population of cardiac progenitor cells (CPCs) through the use of a reporter DNA construct that allowed the expression of a selectable marker under the control of the Nkx2.5 enhancer. We proceeded to characterize these CPCs by examining their capacity to differentiate into cardiomyocytes and to proliferate. We then performed a large-scale temporal microarray expression analysis in order to identify genes that are uniquely upregulated or downregulated in the CPC population. We determined that the transcriptional profile of the mESC derived CPCs was consistent with pathways known to be active during embryonic cardiac development. We conclude that in vitro differentiation of mESCs recapitulates the early steps of mouse cardiac development.
