Global Gene expression data from Mycobacterium tuberculosis treated with new TB drug named Bedaquiline

Project description:Sirturo or Bedaquiline has been shown to inhibit the ATP synthase of Mycobacterium tuberculosis. We used microarrays to investigate compound-induced gene expression changes in general as well as effects on the transcription of the different ATP synthase genes and other metabolic pathways. Log phase Mycobacterium tuberculosis were cultivated in Middlebrook 7H9 broth and treated with 1 M-BM-5M Bedaquiline. We have extracted RNA from five different time-points after treatment: 0 min (T0), 30 min (T30), 60 min (T60), 180 min (T180) and 360 min (T360).

Mycobacterium tuberculosis H37Rv (WT) versus Mut1 and Comp1

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.

The potential role of drug transporters and amikacin modifying enzymes in M. avium

Project description:Background: Mycobacterium avium complex (MAC) bacteria cause opportunistic infections in humans. Treatment yields cure rates of 60% and is comprised of a macrolide, a rifamycin and ethambutol; and in severe cases amikacin. Mechanisms of antibiotic tolerance remain mostly unknown. To elucidate these mechanisms, we studied the transcriptomic response to antibiotics and investigated the contribution of efflux and amikacin modification to susceptibility. Methods: M. avium was subjected to subinhibitory concentrations of clarithromycin, amikacin, ethambutol and rifampicin followed by RNA sequencing. Based thereupon, we characterized M. avium efflux pumps and performed time-kill kinetic analysis using each antibiotic in combination with the efflux pump inhibitors (EPIs) berberine, verapamil and CCCP to study the role of efflux on susceptibility. Finally, we studied the modification of amikacin by M. avium using metabolomic analysis. Results: Changes in respiratory state and changes in ribosome binding and protein folding likely contribute to clarithromycin and amikacin tolerance, respectively. No clear drug-specific mechanisms of tolerance are found for ethambutol and rifampicin. Of the EPIs, only berberine increased the susceptibility to rifampicin and clarithromycin. Finally, we show that M. avium, in contrast to M. abscessus, is not able to modify amikacin. Conclusion: M. avium likely relies on a combination of drug-specific and generic mechanisms of antibiotic tolerance including changes in respiratory and metabolic state in addition to drug efflux and target modification. Efflux inhibition can increase susceptibility but this effect is EPI and antibiotic specific. Finally, the lack of amikacin modifying activity in M. avium is important for its activity.

Subcellular antibiotic visualization reveals a dynamic drug reservoir in infected macrophages

Project description:Tuberculosis, caused by the intracellular pathogen Mycobacterium tuberculosis, remains the world's deadliest infectious disease. Sterilizing chemotherapy requires at least 6 months of multidrug therapy. Difficulty visualizing the subcellular localization of antibiotics in infected host cells means that it is unclear whether antibiotics penetrate all mycobacteria-containing compartments in the cell. Here, we combined correlated light, electron, and ion microscopy to image the distribution of bedaquiline in infected human macrophages at submicrometer resolution. Bedaquiline accumulated primarily in host cell lipid droplets, but heterogeneously in mycobacteria within a variety of intracellular compartments. Furthermore, lipid droplets did not sequester antibiotic but constituted a transferable reservoir that enhanced antibacterial efficacy. Thus, strong lipid binding facilitated drug trafficking by host organelles to an intracellular target during antimicrobial treatment.
