Project description:Comparison of ds-cDNA, Indirect and Direct Random Labeling Methods for gene expression analysis on the NimbleGen platform. Expression profiles from artemisinic acid-producing S. cerevisiae strain EPY330 and non-producing strain EPY338 are compared for each labeling method tested. The labeling methods and their comparison are described in detail in Ouellet et al., BMC Biotech 2009. Strains were described in detail previously in Ro et al.

Project description:The rete ovarii (RO) is an epithelial structure that arises during fetal development in close proximity to the ovary, and persists throughout adulthood in mammals. However, the functional significance of the RO remains elusive and it has been absent from recent discussions of female reproductive anatomy. The RO comprises three distinct regions: the intraovarian rete (IOR) within the ovary, the extraovarian rete (EOR) in the periovarian tissue, and the connecting rete (CR) linking the EOR and IOR. We hypothesize that the RO plays a pivotal role in maintaining ovarian homeostasis and responding to physiological changes. To uncover the nature and function of RO cells, we conducted transcriptome analysis, encompassing bulk, single-cell, and nucleus-level sequencing of both fetal and adult RO tissues using the Pax8-rtTA; Tre-H2B-GFP mouse line, where all RO regions express nuclear GFP. This study presents three datasets, which highlight RO-specific gene expression signatures and reveal differences in gene expression across the three RO regions during development and in adulthood. The integration and rigorous validation of these datasets will advance our understanding of the RO's roles in ovarian development, female maturation, and adult female fertility.

Project description:RNA binding proteins (RBPs) are key regulators of normal and pathological gene expression. Small molecules targeting RBP-RNA interactions are a rapidly emerging class of therapeutics. Ro-08-2750 (Ro) was previously identified as a competitive inhibitor of Musashi-RNA interactions. Here we show Ro potently inhibits steroidogenesis and viability independent of Musashi-2 in multiple cell lines. We identified Ro-interacting proteins using an unbiased proteome-wide approach. Other RBPs were a prominent class of Ro-interacting proteins and leveraging large-scale ENCODE data we found a subset of these phenocopy Ro inhibition. We provide a general framework for validating the specificity and identifying targets of RBP inhibitors in a cellular context.

Project description:Impairment of the intestinal barrier allows the systemic translocation of commensal bacteria, inducing a pro-inflammatory state in the host. To explore this link, we investigated innate immune responses following increased gut permeability upon administration of dextran sulfate sodium (DSS) in mice. We found that microbiota translocation induced trained immunity (TI) in mouse myeloid bone marrow progenitors (BMPs). Enterococcus faecalis was isolated from bone marrow following DSS treatment and induced trained immunity hallmarks in bone marrow-derived mouse macrophages and human monocytes. Notably, DSS treatment or heat-killed E. faecalis reprogrammed BMPs, resulting in enhanced inflammatory responses in vitro and in vivo, and protection against pathogen infections. The C-type lectin receptor Mincle (Clec4e) was essential for E. faecalis-induced TI in BMPs. Clec4e-/- mice showed impaired TI upon E. faecalis and reduced pathology following DSS treatment. Thus, Mincle sensing of E. faecalis induces TI that may contribute to pathologies associated with increased gut permeability. This SuperSeries is composed of the SubSeries listed below.

Project description:This study assess the biocompatibility of Ti-26Nb compared to Ti-Cp, a reference in implantology, through the combination of conventional toxicological assay, morphological observations and transcriptomic analysis performed on two different cells line : Saos-2 and THP-1. The biocompatibility of Ti-Cp implants was evaluated in comparison with Ti-26Nb implants both having a mirror polished surface, studying cell proliferation (trypan blue and WST-1) and cell morphology/adhesion (SEM) on human THP-1 and Saos-2 cell lines. Finally, an evaluation of a potential toxicity of potassium niobiate powder KNbO3 was carried out by measuring metabolic activity and realizing a transcriptomic study on the THP-1 line (the first one) to deepen the results observed with Ti-26Nb discs. Indeed, niobiate ions are potentially released from implant in cellular acidic environnement. Concerning Saos-2 cells, our results suggest that Ti-26Nb and Ti-Cp discs do not impact proliferation and viability. Concerning THP-1 cell line, a decrease in proliferation and viability is observed in contact of Ti-26Nb discs (hypothesis of a cell-line effect ?, no biocompatibility study on monocyte/macrophage cell lines such as THP-1 actually available in literature). KNbO3 powder does not impact viability of THP-1 cells and does not induce changes at molecular level. Taken together, these data suggest a possible toxicity of Ti-26Nb toward THP-1 cells not directly related to the niobium but perhaps to the manufacturing process of Titane niobium alloy.

Project description:T-cell independent type II (TI-II) antigens, such as capsular polysaccharides, have multivalent epitope, which induce B cell activation, plasma cell differentiation and antibody production by strongly cross-linking B cell receptors. However, the mechanism of B cell activation by TI-II antigens remains unclear. In this study, we demonstrate that DNA endonuclease DNase1L3 (also termed DNase g) is required for the TI-II response. The production of antigen-specific antibodies was severely diminished in DNase1L3-deficient mice upon immunization with TI-II antigens, but not with TD antigens. Bone-marrow chimeric mice and B cell transfer experiments revealed that B-cell-intrinsic DNase1L3 was required for the TI-II response. DNase1L3-deficient B cells were defective in cell proliferation and plasma cell differentiation in the TI-II response in vivo as well as in vitro, which was not rescued by co-culture with DNase1L3-sufficient B cells in vitro, disproving an involvement of a secretory DNase1L3. In vitro stimulation with TI-II antigen transiently increased expression of DNase1L3 and its translocation into the nucleus. RNA-seq analysis of ex-vivo B cells having been responded to TI-II antigen in vivo revealed a marked reduction of Myc-target gene sets in DNase1L3-deficient B cells. Expression of IRF4, the gene of which is a target of Myc, was diminished in the ex-vivo DNase1L3-deficient B cells, in which forced expression of IRF4 restored the TI-II response in vivo. These data revealed an unexpected role of DNase1L3 in a missing link between B cell receptor signaling and B cell activation in the TI-II response, giving a valuable clue to molecularly dissect this response.

Project description:Trained immunity (TI) is a pro-inflammatory program induced in monocyte/macrophages upon sensing of specific pathogens and characterized by immunometabolic and epigenetic changes enhancing cytokine production. Maladaptive activation of TI (i.e., in the absence of infection) might result in detrimental inflammation and disease development; however, the exact role and extent of inappropriate activation of TI in the pathogenesis of human diseases is undetermined.
