MetabolomicsBacteria regulate aging physiology in microalgae via induced vesicle production and the methionine cycle (Metabolomics analysis)

In annually reoccurring patterns, microalgae form blooms that persist and decline thereby contributing massively to global biogeochemical cycles. The decline of blooms is mainly caused by nutrient limitation and goes ahead with the aging of individual algal cells. Nutrient intake can re-initiate ...

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...

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...

MetabolomicsMethionine Intervention Induces PD-L1 Expression to Enhance the Immune Checkpoint Therapy Response in MTAP-deleted Osteosarcoma
Osteosarcoma (OS), a malignant bone tumor with limited treatment options, exhibits low sensitivity to immune checkpoint therapy (ICT). Through genomics and transcriptomics analyses, we have identified a subgroup of OS with methylthioadenosine phosphorylase (MTAP) deletion, which contributes to ICT r...

MetabolomicsDisruption of Methionine Metabolism Drives Erythroid Cell Fate Reprogramming by Remodeling the H3K4me3 Landscape

Methionine cycle plays critical roles in cell fate determination by shaping epigenetic landscape, yet its function in human erythropoiesis remains undefined. Here, we show that disruption of methionine metabolism by compromising key enzyme adenosylhomocysteinase (AHCY) reshapes H3K4me3 landscape,...

ProteomicsReduced mitochondria provide an essential function for the cytosolic methionine cycle
Since the discovery of eukaryotes without mitochondria, intestinal flagellates oxymonads, it was clear that the loss of mitochondria was facilitated by the remodelling of the FeS cluster synthesis. Yet, this remodelling is common for a broader linage including free-living species with reduced mitoch...
