Mycoplasma bovis nucleomodulin MbovP202 modulates gene expression in BoMac cells

Project description:We identified a novel M. bovis nucleomodulin, MbovP202, which functions as a 5-methylcytosine-specific DNA methyltransferase that localizes to the nucleus of the bovine macrophage cell line (BoMac). To investigate its regulatory role, we performed RNA sequencing to compare the mRNA expression profiles between BoMac and BoMacMbovP202 cells. A total of 2,790 differentially expressed genes (DEGs) were identified between the two groups. Integrated analysis of Whole Genome Bisulfite Sequencing (WGBS) and RNA-Seq data revealed that genes with promoter hypermethylation and concomitant down-regulated expression were predominantly enriched in metabolic and inflammatory pathways.

Mycoplasma bovis nucleomodulin MbovP202 modulates DNA methylation in BoMac cells

Project description:We identified a novel M. bovis nucleomodulin, MbovP202, which functions as a 5-methylcytosine-specific DNA methyltransferase that localizes to the nucleus of the bovine macrophage cell line (BoMac). Whole genome bisulfite sequencing (WGBS) demonstrated that MbovP202 increases methylation at mCATG sites and mCG sites. Integrated analysis of WGBS and RNA-Seq data revealed that genes with promoter hypermethylation and concomitant down-regulated expression were predominantly enriched in metabolic and inflammatory pathways.

microRNA identification in the Mycoplasma bovis infected mammary gland tissue in Holstein Friesian cattle

Project description:The immune response associated with mastitis caused by Mycoplasma bovis is a very complicated biological process in several type of cells, including immune cells, mammary epithelial cells and, endothelial cells. Thus, revealing of the microRNAs in the Mycoplasma bovis infected mammary gland tissues is particularly important for the immune response mechanism to Mycoplasma bovis. Firstly, mammary gland tissue samples were collected from Holstein cows and screened for Mycoplasma bovis. Then, total RNA was isolated from mycoplasma bovis infected tissues and RNA sequencing was performed. After bioinformatics analysis, GO and KEGG analysis of target genes of identified microRNAs were conducted. Our results revaled that 24 of the known microRNAs were expressed differently and 13 of the novel microRNAs were expressed differently in Mycoplasma bovis positive tissues. The target genes of these microRNAs were found to be associated with especially inflammation pathways. In conclusion, this study demonstrated that identified miRNAs may be involved in the signaling pathways during mastitis case caused by Mycoplasma bovis.

Genome-wide maps of MbovP475-binding sits in BoMac cells.

Project description:We used Next-generation sequencing (NGS) to reveal MbovP475-binding sites in BoMac cells. We extracted the genome of BoMac infected with mycoplasma bovis by sonication, then the sheared chromatin in the supernatant was incubated with purified rabbit polyclonal IgG against MbovP475 and protein A/G magnetic beads. The DNA was eluted from the beads and subject to making sequencing library. We totally got 2648 potential MbovP475-binding sites by ChIP-seq. Among them, CRYAB and MCF2L2 gene were further verifed to be down-reguated by MbovP475 through binding to the promoter region of two genes.

Comprehensive Immunoproteome of Mycoplasma bovis

Project description:This study was aimed to elucidate a global antigenic profile of Mycoplasma bovis (M. bovis) with immunoproteomics, immunoinformatics, and gene expression approaches. The extracts of whole-cell proteins and TX-114 membrane fraction of a Chinese strain M. bovis HB0801 were separated with two dimensional gel electrophoresis (2-DE) and proteins reacting with antisera to M. bovis from experimentally infected calves were detected by MALDI-TOF MS.

Effect of the Mbov_0496 mutation on gene expression of Mycoplasma bovis under normal and high potassium conditions

Project description:Cyclic di-AMP is an essential and ubiquitous second messenger that regulates bacterial potassium (K+) concentrations to maintain osmotic equilibrium. And its specific K+ regulation mechanism in Mycoplasma has rarely been investigated. We used the ruminant pathogen Mycoplasma bovis (M. bovis) to investigate this mechanism. We verified that MbovP496 is a c-di-AMP synthetase and its mutant T5.415 showed growth inhibition under high K+ condition. To deliver why the mutant strain T5.415 can regulate M. bovis growth, we held a RNA-seq analysis to reveal that the differentially expressed genes between WT and T5.415 under normal condition and high K+ condition. The K+ transport pathways and metabolism related pathways were enriched. In conclusion, we found that the mutation of c-di-AMP synthetase, MbovP496 can broadly influence not only the metal ions transport pathway, but also has an effect on metabolism pathways,which could significantly contribute to understanding the regulation of growth by c-di-AMP synthetase in mycoplasmas.

Comparative metabolomics of Mycoplasma bovis and Mycoplasma gallisepticum reveals fundamental differences in active metabolic pathways and suggests novel gene annotations

Project description:Mycoplasmas are simple, but successful parasites that have the smallest genome of any free-living cell and are thought to have a highly streamlined cellular metabolism. Here we have undertaken a detailed metabolomic analysis of two species, Mycoplasma bovis and Mycoplasma gallisepticum, which cause economically important diseases in cattle and poultry, respectively. Untargeted GC/MS and LC/MS analyses of mycoplasma metabolite extracts revealed significant differences in the steady state levels of many metabolites in central carbon metabolism, while 13C stable isotope labelling studies revealed marked differences in carbon source utilization. These data were mapped onto in silico metabolic networks predicted from genome wide annotations. The analyses elucidated distinct differences, including a clear difference in glucose utilisation, with a marked decrease in glucose uptake and glycolysis in M. bovis compared to M. gallisepticum, which may reflect differing host nutrient availabilities. The 13C-labeling patterns also revealed several functional metabolic pathways that were previously unannotated in these species, allowing us to assign putative enzyme functions to the products of a number of genes of unknown function, especially in M. bovis. This study demonstrates the considerable potential of metabolomic analyses to assist in characterising significant differences in the metabolism of different bacterial species, and in improving genome annotation.

Transcription profiling of bovine neutrophils stimulated with Mycoplasma bovis against untreated controls

Project description:Mycoplasma species are highly contagious pathogens, and Mycoplasma infectious disease are a serious issue for the dairy industry. The bovine neutrophils play an important role for the eradication of pathogens which cause mycoplasmal infection, however the effects of M. bovis for immune response of neutrophils have not been fully clarified. We examined the transcription profiling of bovine neutrophils on the stimulation with M. bovis for 3h (3 stimuli, 3 control).
