MetabolomicsOperation of a TCA cycle subnetwork in the mammalian nucleus

Nucleic acid and histone modifications critically depend on tricarboxylic acid (TCA) cycle for substrates and co-factors. Although a few TCA cycle enzymes have been reported in the nucleus, the corresponding pathways are considered to operate in mitochondria. Here, we show that a part of the...

MetabolomicsMitochondrial respiration in B lymphocytes is essential for humoral immunity by controlling flux of the TCA cycle

To elucidate the function of oxidative phosphorylation (OxPhos) during B-cell differentiation we employ CD23Cre-driven expression of the dominant-negative K320E mutant of the mitochondrial helicase Twinkle (DNT). DNT-expression depletes mitochondrial DNA during B cell maturation, reduces the abun...

MetabolomicsABHD11/ROLIP maintains the TCA cycle by preserving functional lipoylation of the 2-oxoglutarate dehydrogenase complex
2-oxoglutarate (2-OG) relates mitochondrial metabolism to cell function: conversion of 2-OG to succinyl-CoA by the 2-OG dehydrogenase complex (OGDHc) is rate-limiting for the Tricarboxylic Acid (TCA) cycle, but 2-OG is also required for oxygen sensitive enzymes (2-OG dependent dioxygenases) that hav...

MetabolomicsChronic Exposure to Environmentally Relevant Doses of Butyl Benzyl Phthalate Promotes Development of Breast Tumor Via the Tricarboxylic Acid Cycle and Fatty Acid β-oxidation

This study investigates the proliferative effects of environmentally relevant exposure to butyl benzyl phthalate (BBP) on triple-negative breast cancer using integrated in vivo and in vitro approaches.

MetabolomicsMetabolomics of red-light-induced stomatal opening in Arabidopsis thaliana: Coupling with abscisic acid and jasmonic acid metabolism
Environmental stimuli-triggered stomatal movement is a key physiological process that regulates CO2 uptake and water loss in plants. Stomata are defined by pairs of guard cells that perceive and transduce external signals, leading to cellular volume changes and consequent stomatal apertur...

ProteomicsOperation of a TCA cycle subnetwork in the mammalian nucleus_mass4tox
Nucleic acid and histone modifications critically depend on central metabolism for substrates and co-factors. Although a few enzymes related to the formation of these required metabolites have been reported in the nucleus, the corresponding metabolic pathways are considered to function elsewhere in ...

TranscriptomicsGene expression analysis of a double knockout of TCA cycle enzymes IDH and KDH
New antimalarial drugs are urgently needed to control drug resistant forms of the malaria parasite, Plasmodium falciparum. Although mitochondrial metabolism is the target of both existing drugs and new lead compounds, the role of the mitochondrial tricarboxylic acid (TCA) cycle remains poorly unders...

TranscriptomicsA non-canonical tricarboxylic acid cycle underlies cellular identity
The tricarboxylic acid (TCA) cycle is a central hub of cellular metabolism, oxidizing nutrients to generate reducing equivalents for energy production and critical metabolites for biosynthetic reactions. Despite the importance of the products of the TCA cycle for cell viability and proliferation, ma...
