MetabolomicsThe oncoprotein SET promotes serine-derived one-carbon metabolism by regulating SHMT2 enzymatic activity
Cancer cells frequently reprogram one-carbon metabolic pathways to fulfill their vigorous demands of biosynthesis and antioxidant defense for survival and proliferation. Dysfunction of oncogenes or tumor suppressor genes is critically involved in this process, but the precise mechanisms by which can...

MetabolomicsThe genomic and enzymatic basis for iridoid biosynthesis in cat thyme (Teucrium marum)
Iridoids are non-canonical monoterpenoids produced by both insects and plants. An example is the cat attracting and insect repelling volatile iridoid nepetalactone, produced by Nepeta sp. (catmint) and aphids. Recently, both nepetalactone biosynthetic pathways were elucidated, showing a remarkable c...

MetabolomicsInterorganelle lipid flux revealed by enzymatic mass tagging in vivo
The distinct activities of cellular organelles are dependent on the proper function of their membranes. Coordinated membrane biogenesis of the different organelles necessitates interorganelle transport of lipids from their site of synthesis to their destination membranes. Several proteins and traffi...

MetabolomicsMetabolic response to point mutations reveals principles of modulation of in vivo enzyme activity and phenotype
The relationship between sequence variation and phenotype is poorly understood. Here, we use metabolomic analysis to elucidate the molecular mechanism underlying the filamentous phenotype of E. coli strains that carry destabilizing mutations in dihydrofolate reductase (DHFR). We find that partial lo...

MetabolomicsMicrobial -Enzymatic Mucin Metabolic Relay Suppresses Tumor Progression in Apcmin/+ mice

Compelling evidence established the gut microbiota as a pivotal regulator of colorectal cancer (CRC) progression, although stage-specific mechanisms remain unclear. Our investigation in Apcmin/+ mice mapped tumor growth and microbial shifts across early, intermediate, and advanced stage...

MetabolomicsMetabolite control of enzyme activity links stress to biosynthetic regulation

Cells must continuously adjust metabolic output to maintain homeostasis under changing environmental conditions, yet the mechanisms that enable rapid and reversible control of pathway activity remain largely unknown. The methylerythritol phosphate (MEP) pathway, of bacterial origin and conserved ...

MetabolomicsUntapped enzymatic potential: dehalogenase- and peroxidase-driven PVC degradation by gene carriers in Tibetan plateau pikas

Wide contamination of MPs including polyvinyl chloride (PVC) has been reported in remote regions such as Qinghai-Tibet Plateau (QTP). Microbial degradation of plastics is frequently coupled with lignocellulose-degrading enzymatic machinery. Given its status as a widespread biological sampler in Q...

MetabolomicsIonomic, Metabolomic, and Enzymatic Responses of the Sea Cucumber Apostichopus japonicus to Single and Combined Salinity and Metal Stress

Desalination brine discharge poses emerging threats to benthic marine organisms through combined salinity stress and metal contamination. This study investigated the individual and combined effects of salinity (35 ppt) and metal exposure (Cu, Fe, and Cd) on the sea cucumber Apostichopus japonicus...

MetabolomicsGinsenoside Rd2 improves allergic asthma by inhibiting PTGS2 enzyme activity
This study aims to elucidate the molecular mechanisms underlying the therapeutic effects of mountain-grown ginseng in allergic asthma and to systematically identify and characterize bioactive monomeric compounds responsible for these effects. We found that total saponins from mountain-grown ginseng ...
