RNA-Seq to investigate gene expression in M. bovis BCG subjected to darG depletion or DNA damage induction with mitomycin D

ABSTRACT: M. bovis BCG bacilli were subjected to silencing of the darG antitoxin gene by CRISPRI, leading to unregulated activity of the toxin DarT. This results in ADP-ribosylation of specific motifs in genomic DNA, and induction of the DNA damage response. The goal of this study is to compare gene expression of M. bovis BCG in untreated, DarG-depleted, and mitomycin treated samples.

M. bovis BCG PknG physiological substrates

Project description:Mycobacterial Ser/Thr kinases play a critical role in bacterial physiology and pathogenesis. Linking kinases to the substrates they phosphorylate in vivo, thereby elucidating their exact functions, is still a challenge. The aim of this work was to associate protein phosphorylation in mycobacteria with important subsequent macro cellular events by identifying the physiological substrates of PknG in Mycobacterium bovis BCG. The study compared the phosphoproteome dynamics during the batch growth of M. bovis BGC versus the respective PknG knock-out mutant (ΔPknG-BCG) strains.

Microarray Analysis of Toxicogenomic Effects of Triclosan on Mycobacterium bovis BCG

Project description:Global gene expression analysis of Mycobacterium bovis BCG following Triclosan treatment using Affymetrix GeneChip arrays. Results from this study provide insight into the molecular mechanisms underlying the cellular response of Mycobacterium bovis BCG to Triclosan We conducted three independent microarray experiments (biological replicates) in the absence (control) and the presence (experimental) of triclosan. Fold change was calculated as a ration between the signal averages of three untreated (control) and three triclosan-treated (experimental) cultures for 0, 10 and 60min exposures.

Microarray Analysis of Toxicogenomic Effects of Hydrogen Peroxide on Mycobacterium bovis BCG

Project description:In the present study, we employed Affymetrix Mycobacterium bovis BCG GeneChip arrays to investigate the dynamics of global gene expression profiles during the cellular response of Mycobacterium bovis BCG to hydrogen peroxide, which involved initial growth inhibition and metabolism. Keywords: Transcriptome study We conducted three independent microarray experiments (biological replicates) in the absence (control) and the presence (experimental) of hydrogen peroxide. We calculated fold change as the ratio between the signal averages of three untreated (control) and three hydrogen peroxide-treated (experimental) cultures for 0, 10 and 60 min exposures.

Comparison of M. tuberculosis and M. bovis BCG in diluted whole blood cultures

Project description:Despite wide scale vaccination with Mycobacterium bovis BCG, the prevalence of tuberculosis remains high, reflecting the global variable efficacy of this vaccine against adult pulmonary TB. Characterisation of different immune responses to M. tuberculosis and M. bovis BCG would increase understanding of pathology following M. tuberculosis infection or reactivation, and would facilitate the rational design of a new vaccine. Gene expression profiling was conducted on samples from diluted whole blood cultures from three healthy donors following incubation with live mycobacteria for six days. Approximately 8,000 gene entities were at least two-fold up- or down- regulated by the mycobacteria, and both mycobacteria induced similar expression changes in approximately 2,300 genes. Strikingly, many genes exhibited qualitatively different expression patterns, with over 1,000 genes up-regulated in response to M. bovis BCG but not changed by M. tuberculosis. Gene Ontology analysis revealed that the genes which failed to upregulate in M. tuberculosis-infected cultures included a large proportion of genes with lysosomal function. The inhibited up-regulation of expression of IFN-γ-inducible protein 30, acid phosphatase 2, cathepsin B and GM2 ganglioside activator was verified in samples from six biologically independent donors by qRT-PCR. The failure to up-regulate these genes in response to M. tuberculosis may constitute an immune evasion mechanism, preventing intracellular killing and antigen presentation. Blood from three healthy BCG-vaccinated donors was diluted with growth medium and incubated alone or with live M. tuberculosis (H37Rv), M. bovis BCG for 6 days. RNA samples were pooled before hybridisation.
