MetabolomicsUntargeted metabolomics links glutathione to bacterial cell cycle progression
Cell cycle progression requires the coordination of cell growth, chromosome replication, and division. Consequently, a functional cell cycle must be coupled with metabolism. However, direct measurements of metabolome dynamics remained scarce, in particular in bacteria. Here, we describe an untargete...

MetabolomicsCDK4/6 inhibitor-mediated cell overgrowth triggers an osmotic stress response and chronic p38MAPK activation to promote long-term cell cycle arrest

Cell size and the cell cycle are intrinsically coupled and abnormal increases in cell size are associated with senescence and permanent cell cycle arrest. The mechanism by which overgrowth primes cells to withdraw from the cell cycle remains unknown. We investigate this here using CDK4/6 inhibito...

MetabolomicsCell overgrowth potentiates osmotic and replication stresses to promote p38/p53/p21-dependent senescence
Abnormal increases in cell size are associated with senescence and cell cycle exit. The mechanisms by which overgrowth primes cells to withdraw from the cell cycle remain unknown. We address this question using CDK4/6 inhibitors, which arrest cells in G0/G1 and are licensed to treat advanced HR+/HER...

MetabolomicsHif1α-Dependent Uncoupling Of Glycolysis Suppresses Tumor Cell Proliferation
Hypoxia-inducible factor-1α (HIF1α) attenuates mitochondrial activity while promoting glycolysis. Paradoxically, it remains unknown why lower glycolysis is compromised in human clear cell renal cell carcinomas (ccRCC), in which HIF1α acts a tumor suppressor by inhibiting cell autonomous proliferatio...

MetabolomicsHypoxia Dependent Inhibition of Glioblastoma Cell Proliferation, Invasion, and Metabolism by the Choline-Kinase Inhibitor JAS239
Background: Elevated choline kinase alpha (ChoK) levels are observed in most solid tumors, including glioblastomas (GBM), and ChoK inhibitors have demonstrated limited efficacy in GBM models. Given that hypoxia is associated with resistance to GBM therapy, we hypothesized that tumor hypoxia c...

MetabolomicsMethionine cycle in C. elegans serotonergic neurons regulates diet-dependent behaviour and longevity through neuron-gut signaling

The folate and methionine cycles (Met-C) are regulated by vitamin B12 (B12), obtained exclusively from diet and microbiota. Met-C supports amino acid, nucleotide, and lipid biosynthesis and provides one-carbon moieties for methylation reactions. While B12 deficiency and polymorphisms in Met-C gen...

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...

MetabolomicsMetabolic balancing by miR-276 shapes the mosquito reproductive cycle and Plasmodium falciparum development
The blood-feeding behavior of Anopheles females delivers essential nutrients for egg development and drives parasite transmission between humans. Plasmodium growth is adapted to the vector reproductive cycle, but how changes in the reproductive cycle impact parasite development remains unclear. Here...

MetabolomicsAmomum longiligulare polysaccharide 1 supplementation promotes the proliferation of jejunal epithelial cells in piglets by regulating the cell cycle and intestinal metabolites

Although nonstarch polysaccharides often have growth-promoting effects in animals, little is known about how polysaccharides act when administered as feed additives. Here, we demonstrate that Amomum longiligulare polysaccharide 1 (ALP1) improves the growth performanc...

MetabolomicsSingle-cell time-resolved multi-omics reveal apoptotic and ferroptotic heterogeneity during foam cell formation

Macrophage-derived foam cell plays a pivotal role in the plaque formation and rupture during the progression of atherosclerosis. Foam cells are destined to divergent cell fate and functions in response to external stimuli based on their internal states, which however is hidden in the traditional ...
