Project description:We developed a serum and animal component-free medium capable of supporting robust growth of the genome-reduced bacterium Mycoplasma pneumoniae. Here, we analyzed the proteome of the wild-type strain grown in serum-free vB13 medium compared to rich medium (Hayflick medium).
Project description:Overall design Hi-C experiments were performed on untreated wild type cells at stationary and drug-treated cells (Novobiocin) of Mycoplasma Pneumoniae MPN129. We studied the chromosome organization of the genome-reduced bacterium, Mycoplasma pneumoniae, which has minimal genetic components and lacks several structural DNA-binding proteins. Platforms : Illumina HiSeq 2000 (Mycoplasma Pneumoniae MPN129)
Project description:The NifA-RpoN complex is a master regulator of the nitrogen fixation genes in alpha-proteobacteria. Based on the complete Rhizobium etli genome sequence, we constructed the R. etli CFN42 oligonucleotide (70 mer) microarray, and utilized this tool to survey changes in gene expression in R. etli CFN42 wild type compared with NifA CFNX247 mutant strain in symbiosis with Phaseolus vulgaris. As expected, the genes associated with a NifA and RpoN binding sites were downregulated in the NifA mutant strain.
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.
