Project description:Transcription analysis of ΔpknK mutant (LIX11) versus wild type H37Rv during logarithmic and stationary phase growth. This will elucidate the genes regulated by PknK during transition from logarithmic growth to stationary phase growth.
Project description:Expression profile of Mycobacterium tuberculosis H37Rv biofilm as induced by DTT (Reduced) 6mM DTT reduced at 6 mM concentration was added to log phase culture of Mtb H37Rv. After 29 hours RNA was isolated and hybridization was done on microarrays
Project description:Transcriptional profiling of Mycobacterium tuberculosis H37Rv and Mycobacterium bovis Ravenel before (i.e., log-phase control) and at 24h and 96h after nutrient starvation. The transcriptional profile of the two strains were compared at log phase, and after 24h and 96h of starvation. In addition, the response of each strain to starvation was examined after 24h and 96h of starvation.
Project description:Transcriptional profiling of Mycobacterium tuberculosis H37Rv strains comparing control DMSO treated strains with Lupulone treated strains. Goal was to determine the effects of Lupulone against Mycobacterium tuberculosis H37Rv strains. Two-condition experiment,control DMSO treated strains vs. Lupulone treated strains. Biological replicates: 2 control replicates, 2 Lupulone replicates.
Project description:Transcriptional profiling of Mycobacterium tuberculosis H37Rv strains comparing control DMSO treated strains with Linezolid treated strains. Goal was to determine the effects of Linezolid against Mycobacterium tuberculosis H37Rv strains. Two-condition experiment,control DMSO treated strains vs. Linezolid treated strains. Biological replicates: 2 control replicates, 2 Linezolid replicates.
Project description:Transcriptional profiling of H37Rv (WT), Mut1 and Comp1 bacteria under aerobic (Aer/0 day, i.e 0 D) and hypoxic conditions (Hyp/5 days standing culture, i.e 5 D). Mut1: H37Rv carrying devR gene disruption by in frame insertion of kanamycin resistance cassette and expressing DevRN-Kan fusion protein. Comp1: Mut1 complemented with low copy number plasmid carrying devR gene expressed from its native constitutive upstream promoter. (Reference: Majumdar et al., 2010, PLoS One 5:e9448). Goal is to compare transcriptional patterns of WT, Mut1 and Comp1 strains under aerobic (0 D) and hypoxic (5 D) conditions in vitro.
Project description:Transcription analysis of M-NM-^TpknK mutant (LIX11) versus wild type H37Rv during logarithmic and stationary phase growth. This will elucidate the genes regulated by PknK during transition from logarithmic growth to stationary phase growth. Two color Experiment,Organism: Mycobacterium tuberculosis, Genotypic Technology designed Custom Mycobacterium tuberculosis H37Rv Whole Genome 8x15k GE Microarray (AMADID-26323 and AMADID-23057
Project description:M. tuberculosis H37Rv was grown in vitro in five different conditions, including four stress conditions that could mimic what M. tuberculosis may experience in macrophages. The gene expression profiling was studied. Methods: Mycobacterium tuberculosis H37Rv strain was grown under 5 different conditions, in duplicate. RNAseq was performed. The gene expression was compared and Differential Expression was analyzed. Results: The gene expression profiling in microaerophilic and stationary phase conditions were the most similar while the profiling in acidic condition was the closest to exponential phase condition. An average 1050 genes were differentially transcribed in each stress condition except for the acidic stress, which had less than 200 genes differentially regulated.
