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.

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.

Project description:Background: Mycobacterium bovis is the causative agent of bovine tuberculosis (BTB), a pathological infection with significant economic impact. Recent studies have highlighted the role of functional genomics to better understand the molecular mechanisms governing the host immune response to M. bovis infection. Furthermore, these studies may enable the identification of novel transcriptional markers of BTB that can augment current diagnostic tests and surveillance programmes. In the present study, we have analysed the transcriptome of peripheral blood leukocytes (PBL) from eight M. bovis-infected and eight control non-infected age-matched and sex-matched Holstein-Friesian cattle using the Affymetrix® GeneChip® Bovine Genome Array with features representing more than 23,000 gene transcripts and over 19,000 gene probe sets. Results: Control and infected animals had similar mean white blood cell counts. However, the mean number of lymphocytes was significantly increased in the infected group relative to the control group (P = 0.001), while the mean number of monocytes was significantly decreased in the BTB group (P = 0.002). Hierarchical clustering analysis using gene expression data from all 5,388 detectable mRNA transcripts unambiguously partitioned the animals according to their disease status. In total, 2,960 gene transcripts were differentially expressed (DE) between the infected and control animal groups (adjusted P-value threshold ≤ 0.05); with the number of genes showing decreased relative expression (1,563) exceeding those displaying increased relative expression (1,397). Systems analysis using the Ingenuity Systems Pathway Analysis (IPA) Knowledge Base revealed an over-representation of DE genes involved in the immune response functional category. More specifically, 64.5% of genes in the affects immune response subcategory displayed decreased relative expression levels in the infected animals compared to the control group. Conclusions: This study demonstrates that genome-wide transcriptional profiling of PBL can distinguish active M. bovis-infected animals from control non-infected animals. Furthermore, the results obtained support previous investigations demonstrating that mycobacterial infection is associated with host transcriptional suppression. These data support the use of transcriptomic technologies to enable the identification of robust, reliable transcriptional markers of active M. bovis infection

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.
