Transcription profiling of Mycobacterium tuberculosis H37Rv wild type and deletion mutants for mce3R gene to investigate the expression of a regulon involved in lipid metabolism

ABSTRACT: Four cultures (four biological replicates) of each of two strains, wild type H37Rv and a deletion mutant for mce3R gene, were grown in in Middlebrook 7H9 medium supplemented with 0.05% Tween 80, or Middlebrook 7H11, supplemented with albumin 0.5%, dextrose 0.4%, and 0.5% glycerol (M7H9-AD-G).
Total RNA was extracted from each culture, dyed with Cy5 and hybridised onto two separated microarrays (technical duplicates).
In the second channel a mix of genomic DNA from strains H37Rv and AF2122 was dyed with CY3 and used as a common control in all the microarrays.
An statistical analysis of microarray data was performed to detect genes with differential expression between genotypes.

High-resolution transcriptome and genome-wide dynamics of RNA polymerase and NusA in Mycobacterium tuberculosis (ChIP-seq)

Project description:To construct a regulatory map of the genome of the human pathogen, Mycobacterium tuberculosis, we applied two complementary high-resolution approaches, strand-specific RNA-seq and ChIP-seq, to survey the global transcriptome and monitor genome-wide dynamics of RNA polymerase (RNAP) and NusA. ChIP-seq revealed that RNAP and the antiterminator, NusA, occurred ubiquitously with the NusA profile mirroring RNAP distribution in both the exponential and stationary phases of growth. Generally, promoter-proximal peaks for RNAP and NusA were observed, followed by a decrease in signal strength reflecting transcriptional polarity. Differential binding of RNAP and NusA in the two growth conditions correlated with transcriptional activity as reflected by RNA abundance. Indeed, a significant association between expression levels and the presence of NusA throughout the gene body was detected, confirming the peculiar transcription-promoting role of NusA. Integration of the datasets pinpointed transcriptional units, mapped promoters and uncovered new anti-sense and non-coding transcripts. Highly expressed transcriptional units were situated mainly on the leading strand, despite the relatively unbiased distribution of genes throughout the genome, thus helping the replicative and transcriptional complexes to align. ChIP-Seq of RNAP and NusA in Mtb H37Rv at exponential and stationary phase cultures. Each experiment was performed in duplicate. Input DNA (No IP) was used as a control.

Quantitative proteomic and phosphoproteomic analysis of H37Ra and H37Rv strains of Mycobacterium tuberculosis

Project description:Mycobacterium tuberculosis, the causative agent of tuberculosis accounts for 1.5 million annual deaths worldwide. The two well-characterized strains of the parental H37 strain namely, H37Ra and H37Rv show different pathogenic phenotypes. In order to identify factors that are responsible for virulence, we compared the proteome and the phosphoproteome profiles of virulent (H37Rv) and virulence attenuated (H37Ra) strains of M. tuberculosis. Quantitative proteomic analysis resulted in the identification and quantitation of 2,709 proteins and 505 phosphosites. Comparative analysis revealed over 5-fold overexpression of several proteins associated with virulence. Our data indicates that there are definable molecular differences between H37Rv and H37Ra strains at both the proteome and phosphoproteome levels which may explain the virulence and phenotypic differences.

Genome-wide mapping of transcriptional start sites defines an extensive leaderless transcriptome in Mycobacterium tuberculosis

Project description:In this study we have combined RNA-seq analysis of genome-wide transcriptional start sites with regular RNA-seq to study the transcriptional landscape of Mycobacterium tuberculosis during exponential culture and growth arrest using a starvation model where exponentially growing cells are incubated in PBS for 24 hours. Three independent biological replicates were used in this experiment.

Computational drug repositioning identifies niclosamide and tribromsalan as inhibitors of Mycobacterium tuberculosis and Mycobacterium abscessus

Project description:Tuberculosis (TB) is still a major global health challenge, killing over 1.5 million people each year, and hence, there is a need to identify and develop novel treatments for Mycobacterium tuberculosis (M. tuberculosis). The prevalence of infections caused by nontuberculous mycobacteria (NTM) is also increasing and has overtaken TB cases in the United States and much of the developed world. Mycobacterium abscessus (M. abscessus) is one of the most frequently encountered NTM and is difficult to treat. We describe the use of drug-disease association using a semantic knowledge graph approach combined with machine learning models that has enabled the identification of several molecules for testing anti-mycobacterial activity. We established that niclosamide (M. tuberculosis IC90 2.95 μM; M. abscessus IC90 59.1 μM) and tribromsalan (M. tuberculosis IC90 76.92 μM; M. abscessus IC90 147.4 μM) inhibit M. tuberculosis and M. abscessus in vitro. To investigate the mode of action, we determined the transcriptional response of M. tuberculosis and M. abscessus to both compounds in axenic log phase, demonstrating a broad effect on gene expression that differed from known M. tuberculosis inhibitors. Both compounds elicited transcriptional responses indicative of respiratory pathway stress and the dysregulation of fatty acid metabolism. Further testing against drug-resistant isolates and other NTM is warranted to clarify the usefulness of these repurposed drugs for mycobacteria.

Hydrogen sulfide stimulates Mycobacterium tuberculosis respiration and growth to exacerbate TB disease

Project description:The aim of this experiment was to determine how exposure of Hydrogen sulfide impacts gene expression in Mycobacterium tuberculosis. RNA was isolated from actively growing mycobacterial cells (0.6-0.8 OD600) using Trizol according to established protocols (27). Briefly, cells were exposed to 25 µM GYY4137 for 1 hr under carefully controlled conditions (n=3/group) and RNA isolated. Unexposed cells received spent GYY4137 (without any capacity to produce Hydrogen sulfide).

Time course RNA-seq of Mycobacterium tuberculosis exposed to nitric oxide.

Project description:Mycobacterium tuberculosis is an intracellular human pathogen with the ability to resist and adapt to many adverse conditions it encounters upon infection. Among these, overcoming the production of nitric oxide by macrophages could be key for M. tuberculosis success. We have challenged M. tuberculosis with a sub-lethal concentration of nitric oxide and followed the transcriptomic response through RNA-seq for 48 hours.

Transcription profiling of mouse lung from C57BL6 and DBA2 parental strains and D2.B6-Chr7 and D2.B6-Chr19 congenic mice following aerosol infection with Mycobacterium tuberculosis for 30 and 70 days

Project description:To gain insight into the host cell types, cellular and molecular pathways possibly involved in the differential permissiveness to pulmonary replication of M. tuberculosis, we carried out transcript profiling studies on M. tuberculosis-infected lungs from congenic and parental strains. We were particularly interested in two groups of transcripts. The first group consists of transcripts which expression in the lung is regulated in response to M. tuberculosis infection (global response to infection), and that is obtained by comparing transcripts profiles of infected vs. uninfected lungs. The second group of transcripts is associated with increased resistance to M. tuberculosis infection of B6 and D2.B6-Chr7 mice. That list consists in the overlap between the lists commonly expressed in response to infection between resistant B6 and D2.B6-Chr7 but that show a significant difference in modulation when compared to infected susceptible D2.<br><br> In these experiments, B6, D2 as well as the D2.B6-Chr19, and D2.B6-Chr7 congenic lines were infected with M. tuberculosis and lungs were harvested at day 30 and day 70, and RNA was prepared. Three independent RNA samples from each group were converted to labeled cDNAs and hybridized to Affymetrix oligonucleotides arrays (Mouse Genome 430 2.0 array). Hybridization results were analyzed with the Genesifter analysis program to characterize changes in gene expression.
