Gene expression in canine uterine bacterial infection

ABSTRACT: The study was undertaken to analyze the effect of canine uterine bacterial infection (Pyometra) on local gene expression patterns in the uteri. The results show profound upregulation of various expected genes related to both the innate and innate immune system. In addition, there was a marked upregulation of many genes associated with proteolysis. Moreover, the bacterial disease resulted in downregulation of a large number of homeobox and zinc finger transcription factors. Keywords: Expression profiling by array

Transcriptomic profiling of canine decidualization and effects evoked by antigestagens on decidualized canine uterine stromal cells

Project description:Maternal-stroma derived decidual cells are the single population in the canine placenta expressing the nuclear progesterone (P4) receptor (PGR), rendering them crucial for the maintenance of canine pregnancy. Indeed, decreased circulating P4 levels or blockage of PGR function with antigestagens (e.g., aglepristone), culminates in the termination of canine pregnancy. As an in vitro model for canine decidualization, dog uterine stromal (DUS; Graubner et al., 2017) cells can be decidualized in vitro with cAMP. The antigestagens aglepristone and mifepristone ablate the expression of decidualization markers in DUS cells (e.g., PGR, PRLR, IGF1 or PTGES). In order to study the mechanisms involved in feto-maternal communication during pregnancy and induction of parturition, the goal of the present work was to assess transcriptional changes mediated by decidualization and antigestagens-induced effects in decidualized DUS cells. Decidualization led to the upregulation of 1841 differentially expressed genes (DEGs, P < 0.01, FDR < 0.01) involved in cellular proliferation and adhesion, mesenchymal-epithelial transition, extracellular matrix organization, and vaso- and immunomodulation. The 1475 DEGs downregulated after decidualization were mostly associated with apoptosis and cell migration. In decidualized DUS cells, aglepristone modulated 1400 DEGs and mifepristone 1558 DEGs. Interestingly, only around half of the identified DEGs were modulated uniquely by one of the antigestagens. In both situations, however, PGR-blockage was associated with an inversion of decidualization-induced effects. Comparison between antigestagens-mediated effects and transcriptional changes in the canine placenta at term allowed the identification of 191 DEGs associated with cell proliferation and adhesion, vascularization and immune activity. These findings emphasize the importance of P4/PGR signaling for decidual cells function.

Biomarkers for canine Leptospira vaccine potency

Project description:We used RNAseq to investigate innate immune responsiveness in canine 030-D cell line induced by inactivated L. interrogans serogroups Canicola and Icterohaemorrhagiae, and two bivalent, non-adjuvanted canine Leptospira vaccines containing the same serogroups. We identified more than 900 DEGs associated with pathways related to innate immune responses in common to these three stimuli. Several molecules including CXCL-10, SAA, and complement factor C3 were identified that could serve as targets for development of a biomarker-based in vitro assay to assess Leptospira vaccine quality. In vitro assay could replace the current animal vaccine-challenge potency assay and contribute to reduction of animal use in vaccine manufacturing.

Biomarkers for canine Leptospira vaccine potency

Project description:Mandatory potency testing of Leptospira vaccine batches relies partially on in vivo procedures, requiring large numbers of laboratory animals. Cell-based assays could replace in vivo tests if biomarkers indicative of Leptospira vaccine potency are identified. We investigated innate immune responsiveness induced by inactivated L. interrogans serogroups Canicola and Icterohaemorrhagiae, and two bivalent, non-adjuvanted canine Leptospira vaccines containing the same serogroups. First, the transcriptome and proteome analysis of canine 030-D cells stimulated with Leptospira strains, and the corresponding vaccine revealed more than 900 DEGs and 23 DEPs in common to these three stimuli. Second, comparison of responses induced by this Leptospira vaccine and a vaccine from another manufacturer revealed a large overlap in DEGs and DEPs as well, suggesting potential to identify biomarkers of Leptospira vaccine activity. Because not many common DEPs were identified, we selected seven molecules from the identified DEGs, associated with pathways related to innate immunity, of which CXCL-10, IL-1β, SAA, and complement C3 showed increased secretion upon stimulation with both Leptospira vaccines. These molecules could be interesting targets for development of biomarker-based assays in the future. Additionally, this study contributes to the understanding of the mechanisms by which Leptospira vaccines induce innate immune responses in the dog.

Canine subcellular Proteomics

Project description:To facilitate canine proteomics research, we have generated a non-redundant canine protein sequence database, with entry name annotation based on sequence similarity to the human proteome. To evaluate the sequence-based annotation transfer, we performed a shotgun proteomics experiment on subcellular fractions of canine spleen.

H3N2 canine influenza virus causes severe clinical signs in dogs with induction of genes related to inflammation and apoptosis

Project description:We demonstrated canine influenza virus (H3N2) pathogenicity to dogs using microarray analysis. Many genes related to innate immunity, such as toll-like receptors, immune cells of natural killer cells, macrophages, neutrophils, nitric oxide and reactive oxygen species, and interferon, were induced. RNA was extracted from canine influenza virus H3N2-infected dogs. The lung RNA of uninfected dogs was used as a negative control. We compared gene expression levels between infected and uninfected dogs using microarray analysis.
