MetabolomicsMetabolomic Characterization of Knock-Out Mutants in Arabidopsis - Development of a Metabolite Profiling Database for Knock-Out Mutants in Arabidopsis (MeKO)
Despite recent intensive research efforts in functional genomics, the functions of only a limited number of Arabidopsis (Arabidopsis thaliana) genes have been determined experimentally. Thus, improving gene annotation remains a major challenge in plant science. Because metabolite profiling can chara...

MetabolomicsMetabolite profiling of Arabidopsis mutants of enzymes of lower glycolysis
We have previously shown that in Arabidopsis the three enzymes of lower glycolysis phosphoglycerate mutase (PGAM), enolase and pyruvate kinase form a complex which play an important role in co-sub-cellar localization the mitochondria to the chloroplast. Given that their metabolites of these mutants,...

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...

MetabolomicsThe Bardet-Biedl protein Bbs1 controls photoreceptor outer segment protein and lipid composition

Summary

Primary cilia are key sensory organelles whose dysfunction leads to ciliopathy disorders such as Bardet-Biedl syndrome (BBS). Retinal degeneration is common in ciliopathies, since the outer segments (OSs) of photoreceptors are highly specialized primary cilia. BBS...

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...

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...

MetabolomicsPrimary Osteocyte Supernatants Metabolomic Profiling of Two Transgenic Mice with Connexin43 Dominant Negative Mutants

Osteocytes could release some small molecules (≤ 1 kDa) through gap junctions and hemichannels to extracellular environment, such as prostaglandin E2 (PGE2), nitric oxide (NO) and adenosine triphosphate (ATP), which play key roles in transferring signals between bone cells and other tissue cells....

MetabolomicsLipidomics study for investigating the role of the Unfolded Protein Response In Arabidopsis seed filling

The Unfolded Protein Response (UPR) is a retrograde, ER-to-nucleus, signalling pathway which is conserved across kingdoms. In plants, it contributes to development, reproduction, immunity and tolerance to abiotic stress. This lipidomic dataset was produced from Arabidopsis thaliana mature seeds. ...

MetabolomicsFatty acid transport protein 4 is required for incorporation of saturated ultralong-chain fatty acids into epidermal ceramides and monoacylglycerols
Fatty acid transport protein 4 (FATP4) is an acyl-CoA synthetase that is required for normal permeability barrier in mammalian skin. FATP4 (SLC27A4) mutations cause ichthyosis prematurity syndrome, a nonlethal disorder. In contrast, Fatp4-/- mice die neonatally from a defective barrier. H...
