MetabolomicsComparative label-free lipidomic analysis of Mycobacterium tuberculosis during dormancy and reactivation
Mycobacterium tuberculosis employs several strategies to combat and adapt to adverse conditions encountered inside the host. The non-replicative dormant state of the bacterium is linked to drug resistance and slower response to anti-tubercular therapy. It is known that alterations in lipid content a...

MetabolomicsExploiting Vitamin B6 Dependency: BVL3572S Inhibits HisC and AlaA to Kill Mycobacterium tuberculosis

Tuberculosis remains the leading cause of death from a single infectious agent worldwide, and the growing prevalence of multi-drug resistant Mycobacterium tuberculosis (Mtb) underscores the urgent need for antibiotics with novel mechanisms of action. Here, we characterize BVL3572S, a hydroxamic a...

MetabolomicsGeneration and characterization of thiol-deficient Mycobacterium tuberculosis mutants
Mycothiol (MSH) and ergothioneine (ERG) are thiols able to compensate for each other to protect mycobacteria such as Mycobacterium smegmatis against oxidative stress. Gamma-glutamylcysteine (GGC), another thiol and an intermediate in ERG biosynthesis has detoxification abilities. Five enzymes are in...

MetabolomicsRv3400 is a phosphoglucomutase required for trehalose metabolism in Mycobacterium tuberculosis

Mycobacterium tuberculosis is a global killer causing over a million deaths from tuberculosis (TB) every year. It is therefore a major burden on human health. To reduce the deadly impact of TB, we need a better understanding of the strategies used by M. tuberculosis to adapt its...

MetabolomicsAspartate aminotransferase Rv3722c governs aspartate-dependent nitrogen metabolism in Mycobacterium tuberculosis

Gene rv3722c of Mycobacterium tuberculosis is essential for in vitro growth, and encodes a putative pyridoxal phosphate-binding protein of unknown function. Here we use metabolomic, genetic and structural approaches to show that Rv3722c is the primary aspartate aminotransferase of M. tuberculosis...

MetabolomicsIntegration of metabolomics and transcriptomics reveals major metabolic pathways and potential biomarkers involved in pulmonary tuberculosis and pulmonary tuberculosis-complicated diabetes

Pulmonary tuberculosis (PTB) and diabetes mellitus (DM) are common chronic diseases that threaten human health. Patients with DM are susceptible to PTB, an important factor that aggravates the complications of diabetes. However, the molecular regulatory mechanism underlying the susceptibility of ...

TranscriptomicsDual RNA-seq of M. tuberculosis H37Rv infecting macrophage-like THP-1 cells during 48h
Transcriptional changes during early infection of macrophage-like THP-1 cell line with pathogenic bacterium Mycobacterium tuberculosis. RNAseq samples were taken at 0h (THP-1 cells growing in the RPMI medium), and after 4h, 24h and 48h post infection. Bacterial enrichment was performed to increase t...

GenomicsThe PhoP-dependent ncRNA Mcr7 modulates the TAT secretion system in Mycobacterium tuberculosis [ChIP-Seq]
The PhoPR two-component system is essential for virulence in Mycobacterium tuberculosis where it controls expression of approximately 2% of the genes, including those for the ESX-1 secretion apparatus, a major virulence determinant. Mutations in phoP lead to compromised production of pathogen-specif...

MetabolomicsNovel Potential Diagnostic Serum Biomarkers of Metabolomics in Osteoarticular Tuberculosis Patients: A Preliminary Study

Osteoarticular tuberculosis is one of the extrapulmonary tuberculosis, which is mainly caused by direct infection of Mycobacterium tuberculosis or secondary infection of tuberculosis in other parts. Due to the low specificity of the current detection method, it is leading to a high misdi...

MetabolomicsSerum untargeted metabolomics reveals distinct metabolic signatures and potential biomarkers in female and latent genital tuberculosis

Female genital tuberculosis (FGTB) and latent genital tuberculosis (LGTB) critically impair women's reproductive health. However, their early diagnosis and treatment remain challenging due to nonspecific symptoms and suboptimal diagnostic methods. This study utilized serum untargeted metabolomics...
