MetabolomicsLysine acetyltransferase Rv0998 coordinates transcriptional and metabolic adaptation of Mycobacterium tuberculosis to acidic pH

Mycobacterium tuberculosis (Mtb) survives host defences by adapting to host conditions, including acid stress, during infection. A critical survival strategy involves pH homeostasis, mediated by complex signalling systems that regulate metabolic reprogramming and stress responses. While ...

ProteomicsSigma E of Streptomyces coelicolor can function both as a direct activator or repressor of transcription
Sigma factors are key components of the bacterial transcriptional apparatus that are essential for promoter recognition and transcription initiation. These factors are considered as positive regulators of gene expression. Here, we reveal the opposite, inhibitory role of these proteins. We used a com...

GenomicsThe Mediator complex subunit MED23 couples H2B mono-ubiquitination to transcriptional control and cell fate determination
The Mediator complex orchestrates multiple transcription factors with the Pol II apparatus for precise transcriptional control. However, its interplay with the surrounding chromatin remains poorly understood. Here, we analyze differential histone modifications between WT and MED23-/- (KO) cells and ...

TranscriptomicsFlagellar export apparatus protein, FliH, is involved in post-transcriptional regulation of FlaB, motility and virulence of the relapsing fever spirochete Borrelia hermsii
Spirochetes are long, thin, motile, helical or flat wave bacteria that are unique among the prokaryotes by having flagella or axial filaments confined to an internal periplasmic space. These flagella are complex organelles that can play major roles in bacterial pathogenicity and are used as propelle...

TranscriptomicsPromoter proximal pausing and its regulation by c-Myc in embryonic stem cells: ChIP-chip
Recruitment of the RNA Polymerase II (Pol II) transcription initiation apparatus to promoters by specific DNA binding transcription factors is well recognized as a key regulatory step in gene expression. We describe here evidence that promoter-proximal pausing is a general feature of transcription ...

TranscriptomicsThree-dimensional low shear culture of Mycobacterium bovis BCG induces biofilm formation and antimicrobial drug tolerance
Mycobacteria naturally grow as corded biofilms in liquid media without detergent. Such detergent-free biofilm phenotypes may reflect the growth pattern of bacilli in tuberculous lung lesions. New strategies are required to treat tuberculosis that is responsible for more deaths each year than any oth...

TranscriptomicsContribution of Veillonella parvula to Pseudomonas aeruginosa mediated pathogenicity in a murine tumor model system
We investigated the specific interactions of the most dominant bacterial CF-pathogen, Pseudomonas aeruginosa, and the anaerobic bacterium Veilllonella parvula, that has been recovered at comparable cell numbers in the respiratory tract of CF patients. We used our recently established in-vivo murine ...

TranscriptomicsA high resolution map of a cyanobacterial transcriptome
Previous molecular and mechanistic studies have identified several principles of prokaryotic transcription, but less is known about the global transcriptional architecture of bacterial genomes. Here we perform a comprehensive study of a cyanobacterial transcriptome, that of Synechococcus elongatus P...
