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...

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.

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...

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...

MetabolomicsDecoding the Regulatory Networks of Proteus mirabilis Under Succinic Acid Stress: A Multi-Omics Approach

Proteus mirabilis, a key catheter-associated urinary tract infection pathogen that forms antibiotic-resistant crystalline biofilms, was shown via multi-omics analyses to be multimodally inhibited by succinic acid. At 15 mM, succinic acid reduced the bacterium’s growth by 70% and biofilm formation...

TranscriptomicsLemon_acidity
Samples from fruit juice vesicle tissue from three lemon genotypes (Frost Lisbon, Faris "sour" and Faris "sweet") differing in fruit acidity were compared at two developmental timepoints (immature, mature). Faris lemon appears to be a graft chimera with the L2 layer derived from ...

TranscriptomicsThe YbjN regulon in Escherichia coli
YbjN, an enterobacteria-specific protein, is a multicopy suppressor of ts9 temperature sensitivity in Escherichia coli. Microarray study revealed that the expression level of ybjN was inversely correlated with the expression of flagellar, fimbrial and acid resistance genes. Over-expression of ybjN ...
