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...

MetabolomicsMetabolic and transcriptional response of Arabidopsis thaliana wildtype and mutants to Phytophtora infestans
The oomycete P. infestans is the causal agent of late blight, the most devastating potato disease. In contrast to potato, A. thaliana is able to successfully prevent colonization of the pathogen due to a multi-layered nonhost resistance. Several mutants have been isolated which are impaired in penet...

MetabolomicsPseudomonas syringae infectivity correlates to altered transcript and metabolite levels of Arabidopsis Mediator mutants

Rapid metabolic responses to pathogens are essential for plant survival and depend on numerous transcription factors. Mediator is the major transcriptional co-regulator for integration and transmission of signals from transcriptional regulators to RNA polymerase II. Using four Arabidopsis Mediato...

MetabolomicsIntegrated transcriptomics and metabolomics analysis of gasa1 and gasa4 mutants in response to P.syringae infection in Arabidopsis

The Gibberellic acid-stimulated Arabidopsis (GASA) gene family encodes a class of cysteine-rich proteins characterized by an N-terminal signal peptide and a conserved C-terminal GASA domain containing 12 cysteine (Cys) residues. These plant-specific small proteins have been identified across vari...

MetabolomicsInorganic Carbon Limitation in Cells of the Wild Type and Photorespiratory Mutants of the Cyanobacterium Synechocystis sp. Strain PCC 6803
The amount of inorganic carbon represents one of the main environmental factors determining productivity of photoautotrophic organisms. Using the model cyanobacterium Synechocystis sp. PCC 6803, we performed a first metabolome study with cyanobacterial cells shifted from high CO2 (5% in air) into co...

MetabolomicsPathogenic NLRP3 mutants form constitutively active inflammasomes resulting in immune-metabolic limitation of IL-1β production

BACKGROUND: Cryopyrin-Associated Periodic Syndrome (CAPS) is an autoinflammatory condition consequence of monoallelic variants in the NLRP3 gene that exacerbate IL-1β production. These variants are gain-of-function, but the exact regulatory mechanism of the NLRP3 CAPS-inflammasom...

TranscriptomicsIdentification of common features proffered by KIT and PDGFRA mutations in gastro-intestinal stromal tumors
Mutations in KIT proto-oncogene receptor tyrosine kinase (KIT) or platelet derived growth factor receptor alpha (PDGFRA) are responsible for more than 85% of the gastrointestinal stromal tumors (GIST). The introduction of imatinib in the therapy scheme of GIST revolutionized the patient outcome. Unf...

TranscriptomicsPseudomonas aeruginosa lasR mutants in young cystic fibrosis patients
Pseudomonas aeruginosa undergoes genetic change during chronic infection of the airways of cystic fibrosis (CF) patients. One common change is mutation of lasR. LasR is a transcriptional regulator that responds to one of the quorum sensing signals in P. aeruginosa, and regulates acute virulence fa...

TranscriptomicsA microRNA microarray analysis of C.elegans Parkinsons disease models
MicroRNAs (miRNAs) play an important role in human brain development and maintenance. To search for miRNAs potentially involved with molecular mechanisms in the pathogenesis of Parkinsons disease (PD), we utilized miRNA microarrays to identify expression changes of 115 annotated Caenorhabditis elega...
