Project description:Comparison of gene expression profile of the whiB4 mutant strain of Mycobacterium tuberculosis with the wild type Mycobacterium tuberculosis H37RV Mtb WhiB4 mutant mRNA was compared with the mRNA of wtMtb H37RV under aerobic conditons
Project description:Transcriptional profiling of SirR and manganese regulated expression of genes in Mycobacterium tuberculosis strains comparing high manganese vs. low manganese in Rv (wild type Mycobacterium tuberculosis) and ST70 (mntR mutant strain of Mycobacterium tuberculosis)
Project description:We report the effects of VapC21 overexpression on Mycobacterium tuberculosis H37Rv strain. The total RNA was isolated from M. tuberculosis harboring either pTetR-int or pTetR-Int-vapC21 the expression was induced with 50 ng/ml anhydrotetracycline for 24 hrs. We report the effect of deletion VapC21 on the transciptional profile of Mycobacterium tuberculosis Erdman strain. For RNA-seq analysis, total RNA was isolated from mid-log phase culture of either parental or △vapC21 mutant strain.
Project description:Transcriptional profiling of SirR and manganese regulated expression of genes in Mycobacterium tuberculosis strains comparing high manganese vs. low manganese in Rv (wild type Mycobacterium tuberculosis) and ST70 (mntR mutant strain of Mycobacterium tuberculosis) Two strains each with two conditions experiment, Rv (Mycobacterium tuberculosis wild type strain) high manganese vs. low manganese and ST70 (mntR mutant strain of Mycobacterium tuberculosis) high manganese vs. low manganese. Number of biological replicates is 3 for each condition for each strain.
Project description:Comparison of gene expression profile of the whiB4 mutant strain of Mycobacterium tuberculosis with the wild type Mycobacterium tuberculosis H37RV Mtb WhiB4 mutant mRNA was compared with the mRNA of wtMtb H37RV under aerobic conditons Aerbic conditions OD600 nm of 0.4, MtbWhiB4KO vs wtMtb, biological replicates: 3 wt Mtb H37RV and 3 MtbWhiB4 KO
Project description:We report the effects of MazF6 overexpression on Mycobacterium tuberculosis H37Rv strain. The total RNA was isolated from M. tuberculosis harboring either pTetR-int or pTetR-Int-mazF6 the expression was induced with 50 ng/ml anhydrotetracycline for 24 hrs.
Project description:Transcriptional profiling of gyr(-) strain of Mycobacterium tuberculosis H37Ra comparing 20ng/ml ATc treated cells with ATc-untreated cells after 4 days of treatment with shaking at 200rpm at 37°C.
Project description:The cytokine IL-10 deactivates macrophages and has been shown to impair resistance to mycobacterial infection. We have infected transgenic mice overexpressing IL-10 under control of the macrophage-specific CD68 promoter (macIL-10tg mice) with Mycobacterium tuberculosis by aerosol and found increased bacterial loads in the lungs of macIL-10tg mice. To identify programs of genes regulated by IL-10 and associated with increased mycobacterial replication, genome-wide expression analysis was performed. Experiment Overall Design: Impact of IL-10 pulmonary gene expression in mouse M. tuberculosis infection
Project description:Bacterial persister cells are phenotypic variants of regular cells that are tolerant to antibiotics. High-persister (hip) mutants of Mycobacterium tuberculosis produce 10- to 1,000-fold more persister cells than the wild type strain when challenged with various antibiotics. Comparison of gene expression pattern of the hip mutants may provide clues as to the genetic mechanisms underlying persister formation. Transcriptome analysis will provide information on what differentiates M. tuberculosis hip strains from regular strains, which will be useful in the development of anti-persister therapy for persister cell eradication.
