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...

MetabolomicsUnravelling age-driven molecular transitions underlying Pacific Oyster Mortality Syndrome permissiveness in Magallana gigas

Ageing is a progressive and irreversible biological process characterized by the deterioration of physiological functions and increased vulnerability to mortality. Although extensively studied in vertebrates, ageing in long-lived invertebrates remains comparatively unexplored. While ageing typica...

ProteomicsComparative proteomic study on liver lipid droplets and mitochondria from mouse housed in different temperatures
Laboratory mice are standardly housed around 23ºC, setting them under chronic cold stress. Metabolic changes of liver in mice housed under thermoneutral, standard and cold temperatures remain unknown. Here we isolated lipid droplets and mitochondria from their livers for comparative proteomic study ...

ProteomicsAge-Related Disruption of the Proteome and Acetylome in Mouse Hearts Correlates with Differential Loss of Function that is Attenuated by SS-31 and NMN
We analyzed the effects of aging on protein abundance and acetylation, as well as the ability of the mitochondrial-targeted drugs SS-31 and NMN to reverse age-related changes, in mouse hearts. Both drugs had a modest effect on restoring the abundance and acetylation of proteins that are lost with ag...

MetabolomicsTargeted metabolomics analysis by LC-MS/MS for BMDCs infected with VSV
Virus-infected cells often exhibit dramatic cellular changes accompanied by altered mitochondrial function. The contribution of factors shaping the inner mitochondrial membrane (IMM) and cristae architecture on viral replication is insufficiently understood. Single cell transcriptomics applying vesi...

ProteomicsOperation of a TCA cycle subnetwork in the mammalian nucleus
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 metabolites have been reported in the nucleus, the corresponding metabolic pathways are considered to function elsewhere in the cell....
