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 ...

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 ...

MetabolomicsRegulatory mechanisms for aromatic carbon metabolism in Comamonas testosteroni
Widely reported discrepancies between metabolic flux and transcripts or enzyme levels in bacterial metabolism imply complex regulation mechanisms need to be considered, especially in new bacterial platforms for bioremediation and bioproduction. Comamonas testosteroni strains, which metabolize variou...

MetabolomicsIntegrated metabolomic and transcriptomic analysis reveals the neurotoxicity and mechanisms of Shengfu Pian

Background: The mechanisms underlying neurological toxicity are complex. Shengfu Pian (SFP), a traditional Chinese medicine, has drawn increasing attention due to its potential neurotoxic effects.

Methods: To investigate the neurotoxic mechanisms of SFP, we first applied non-targeted serum ...

MetabolomicsCommunity metabolomics provides insights into mechanisms of pollution-induced community tolerance of periphyton

Chemical pollution is a major concern for freshwater ecosystems, but the impact and mechanisms of chemical stressors on communities are barely understood. Pollution stress beyond natural homeostatic capacities can trigger succession of tolerant species within a community, enhancing the overall co...

MetabolomicsIntegrative transcriptomic, metabolomic, and physiological analyses reveal the root adaptive mechanisms of common vetch (Vicia sativa L.) under drought stress
Drought is a major abiotic stress that limits the productivity and ecological adaptability of leguminous forage crops. As the primary organs that sense soil water deficits, roots play an essential role in plant adaptation to drought. Common vetch (Vicia sativa L.) is an important annual leguminous f...

MetabolomicsConserved cellular signals and mechanisms accompany the reproductive shutdown of honey bee (Apis mellifera) queens for dispersal
Temporal reproductive plasticity is a central life-history trait for most iteroparous animals, yet its underlying molecular mechanisms remain poorly understood. We utilize the reversible reproductive arrest experienced by honey bee queens during colony swarming to investigate how these reproductive ...
