RNA-seq was used to determine the miRNAs expression profiles of Ctrl-EVs and M. bovis NX2-EVs.

ABSTRACT: In this work, we detect the effect of EVs derived from M. bovis-infected BMEC cells (M. bovis NX2-EVs) on regulating the inflammatory response of BoMac. The results indicate M. bovis-infected BMEC cells promote the inflammatory response in BoMac cells by releasing EVs. We furtherly identify the miRNAs in EVs involved in promoting inflammatory response. Understanding their cargo content will provide new insights into the molecular mechanisms of these respective EVs.

Effect of M . bovis NX2-EVs on gene expression in BoMac cells

Project description:Our research shows that EVs derived from M. bovis-infected BMEC cells (EVs-M. bovis NX2) could regulate BoMac cell injury by inducing inflammation. To detect the effect of EVs-M. bovis NX2 on gene expression in BoMac cells, we incubated Ctrl-EVs and EVs-M. bovis NX2 with BoMac cells for 12h, 24h. Our data provide globaly change of mRNA profile caused by EVs-M. bovis NX2.

Transcription profiling of bovine mammary epithelial cells stimulated with Mycoplasma bovis against untreated controls

Project description:Mycoplasma species are highly contagious pathogens, and intramammary Mycoplasma infection is a serious issue for the dairy industry. The bovine mammary epithelial cells (bMEC) play an important role for the eradication of pathogens which cause intramammary infection, however the effects of M. bovis for immune response of bMEC have not been fully clarified. We examined the transcription profiling of bMEC on the stimulation with M. bovis for 6h (3 stimuli, 3 control).

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.

Inflammatory and immune responses in lymph nodes of Iberian red deer infected with Mycobacterium bovis.

Project description:Bovine tuberculosis (bTB), caused by Mycobacterium bovis (Mycobacterium tuberculosis complex), is a zoonotic disease that affects cattle and wildlife worldwide. In some regions of Spain, Iberian red deer (Cervus elaphus hispanicus) can serve as reservoir of infection, thus increasing the risk of human and cattle exposure and infection. Mesenteric lymph nodes are naturally infected with M. bovis in Iberian red deer, in which the digestive route of infection is particularly important in Mediterranean Spain. In this study we characterized the differential expression of inflammatory and immune response genes in mesenteric lymph nodes of Iberian red deer naturally infected with M. bovis using a Ruminant Immuno-inflammatory Gene Universal Array (RIGUA) and real-time RT-PCR. Of the 600 genes that were analyzed in the microarray, 157 showed ? 1.2 fold changes in expression in infected or uninfected deer and 17 genes displayed an expression fold change greater than 1.7 with a P-value ? 0.05 and were selected for further analysis. These genes included tight junction proteins (Z02 and occluding), IL-11R, bactenecin, CD62L, CD74, desmoglein, IgA and IgM that constitute new findings and suggest new mechanisms by which M. bovis may modulate host inflammatory and immune responses. Identification of genes differentially expressed in animals and tissues naturally infected with M. bovis contributes to our basic understanding of the mechanisms of pathogenesis and protective immunity to mycobacterial infections and may have important implications for future functional genomic and vaccine studies to aid in the control of bTB in deer and other wildlife reservoir species. Mesenteric lymph node RNA from four different uninfected Iberian red deer stags and two Iberian red deer stags infected with Mycobacterium bovis. Infected animals were naturally infected with M. bovis. All animals were hunter-harvested and the tissues retrieved 2-6 hrs after animal hunting.

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 Analysis of mRNAs and lncRNAs in Mycoplasma Bovis infected and non-infected bovine mammray gland tissues.

Project description:Mycoplasma bovis (M. bovis) causes to the diseases such as arthritis, pneumonia, abortion and mastitis causing to great losses in dairy bovine industries. It undertakes significant functions in the regulation of the immune response formed by many RNA type bacteria such as Messenger RNA (mRNAs) and Long noncoding RNA (lncRNAs). mRNA and lncRNA expression profiles still cannot be majorly known in the bovine mammary gland tissues infected with M. bovis. To illuminate this issue, transcription analysis has been conducted regarding mRNA and IncRNAs in the breast tissues belonging to Holstein cattle infected and not infected with M. Bovis. Differently expressed 1310 mRNAs and 57 IncRNAs have been determined in the bovine mammary gland tissues infected and not infected with M. Bovis. In addition; 392 novel lncRNAs have been detected. Also; it has been found that 19 novel lncRNAs are expressed in a different way. It has been revealed in gene ontology analysis that the differently expressed mRNAs and IncRNAs play a significant role in many vital biological pathways such as Metabolic pathways, T cell receptor signaling pathway, TGF-beta signaling pathway, Pathways in cancer, PI3K-Akt signaling pathway, NF-kappa B signaling pathway, mTOR signaling pathway and Apoptosis including the immune response and cancer. When literature review is conducted, it is seen that this study is the first genome wide IncRNA research conducted on the infected bovine mammary gland tissues with M. bovis agent. Our results have provided bovine mammary gland IncRNA and mRNA resource to understand their roles in the regulation of the immune response against the agent of M. Bovis in the bovine mammary gland tissues.
