MetabolomicsDefective cytokinin signaling reprograms lipid and flavonoid gene-to-metabolite networks to mitigate high salinity in Arabidopsis

Cytokinin (CK) in plants regulates both developmental processes and adaptation to environmental stress. Arabidopsis histidine phosphotransfer ahp2,3,5 and type-B response regulator arr1,10,12 triple mutants are almost completely defective in CK signaling, and the ahp2,3,5

MetabolomicsMechanisms of exogenous quercetin in enhancing soybean salt tolerance through regulating ion homeostasis, phytohormone signaling, and flavonoid metabolism

Increasing soil salinization poses a severe threat to global agricultural production. Quercetin, a natural compound known to effectively alleviate abiotic stress, has an unclear molecular regulatory mechanism in enhancing soybean salt tolerance. To investigate its mechanism of action, this study ...

MetabolomicsA neurotoxic cellular stress response linked to dark microglia and toxic lipid secretion

Microglia, the brain’s primary resident immune cells, can assume various phenotypes with diverse functional outcomes on brain homeostasis. In Alzheimer’s disease (AD), where microglia are a leading causal cell type, the identity of microglia subsets that drive neurodegeneration remains unresolved...

MetabolomicsMulti-omics profiling identifies MAPK signaling suppression associated with tetracycline-induced root toxicity in soybean
Tetracycline (TC), a widely used veterinary antibiotic, is a pervasive emerging contaminant threatening crop production. Here, we employed integrated physiological, metabolomic, and transcriptomic analyses to decipher the response of soybean (Glycine max L.) to TC. While seed germination was unaffec...

MetabolomicsMetabolomics-Based Analysis of Adaptive Mechanism of Eleutheronema tetradactylum to Low-Temperature Stress

Temperature is a critical environmental factor influencing fish physiology. Eleutheronema tetradactylum is an economically important warm-water species, but its response to long-term cold stress remains unclear. In this study, we exposed juvenile fish to 18 °C for 7 and 14 days and investigated h...

MetabolomicsThe dynamic clustering of insulin receptor underlies its signaling and is disrupted in insulin resistance
Insulin receptor (IR) signaling is central to normal metabolic control and is dysregulated in metabolic diseases such as type 2 diabetes. We report here that IR is incorporated into dynamic clusters at the plasma membrane, in the cytoplasm and in the nucleus of human hepatocytes and adipocytes. Insu...

MetabolomicsOPA1 promotes ferroptosis by augmenting mitochondrial ROS and suppressing an integrated stress response

Ferroptosis, an iron-dependent form of nonapoptotic cell death mediated by lipid peroxidation, has been implicated in the pathogenesis of multiple diseases. Subcellular organelles play pivotal roles in the regulation of ferroptosis, but the mechanisms underlying the contributions of the mitochond...

MetabolomicsIAPP toxicity activates HIF1α/PFKFB3 signaling delaying β-cell loss at the expense of β-cell function
The islet in type 2 diabetes (T2D) is characterized by amyloid deposits derived from islet amyloid polypeptide (IAPP), a protein co-expressed with insulin by β-cells. In common with amyloidogenic proteins implicated in neurodegeneration, human IAPP (hIAPP) forms membrane permeant toxic oligomers imp...

MetabolomicsEnergy-stress-mediated AMPK activation inhibits ferroptosis

Energy stress depletes ATP and induces cell death. Here we identify an unexpected inhibitory role of energy stress on ferroptosis, a form of regulated cell death induced by iron-dependent lipid peroxidation. We found that ferroptotic cell death and lipid peroxidation can be inhibited by treatment...

MetabolomicsMetabolomics study for investigating chronic endoplasmic reticulum stress in Arabidopsis thaliana

The Unfolded Protein Response (UPR) is a retrograde, ER-to-nucleus, signalling pathway which is conserved across kingdoms. In plants, it contributes to development, reproduction, immunity and tolerance to abiotic stress. This metabolomic dataset was produced from 14-day-old Arabidopsis thaliana s...
