Transcriptome analysis of MazF6 overexpression in Mycobacterium tuberculosis
Ontology highlight
ABSTRACT: 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: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:We report the effects of VapC11 overexpression on Mycobacterium tuberculosis H37Rv strain. VapC11 is a tRNase which specifically cleaves tRNA-Leu^CAG (leuT).Cells harbouring either pTetR (Control) or pTetR-vapC11 was used to understand the effect of VapC11 toxin overproduction on cellular transcriptome.

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 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.
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.
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:The new microarray described for Mycobacterium tuberculosis in our study has a more complete reprensentation of the genome than any other array design reported till date. Further, protocols for sample preparation, labelling and hybridisation for accurate gene expression profiling of M.tuberculosis have been optimised. Whole genome expression profiling on Mycobacterium tuberculosis H37Rv (OD600 0.4-0.5) was performed using exponential phase cultures after 0 and 6 Hrs in presence and absence of drug (Isoniazid) by using PolyA-dT and WT method. The exponential culture after 24 and 72 Hrs were used for validating the specific hybridization with or without formamide. All time points had two biological replicates with two technical replicates.
Project description:Using Total RNA sequencing, We report the effects of VapC13 and VapC26 overexpression on the transcriptome of M. tuberculosis. For RNA-seq experiments, early-log phase cultures (OD600nm ~ 0.2-0.3) of M. tuberculosis strains harboring either pTetR or pTetR-vapC13 or pTetR-vapC26 were induced with the addition of 50 ng/ml Atc for 24 h. For total RNA isolation, induced cultures were harvested by centrifugation, washed twice with 1x PBS and lysed by bead beating in Trizol. Total RNA was extracted by phenol-chloroform, precipitated with isopropanol and eluted using Qiagen RNA isolation kit as per manufacturer’s instructions. We report that VapC13 or VapC26 resulted in increased transcripts levels of stress responsive genes of M. tuberculosis.
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.
