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...

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...

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...

MetabolomicsGlobal Metabonomic and Proteomic Analysis of Human Conjunctival Epithelial Cells (IOBA-NHC) in Response to Hyperosmotic Stress
“Dry eye” is a multi-factorial inflammatory disease affecting the ocular surface. Tear hyperosmolarity in dry eye contributes to inflammation and cell damage. Recent research efforts on dry eye have been directed towards biomarker discovery for diagnosis, response to treatment and disease mechanisms...

MetabolomicsSnail reprograms glucose metabolism by repressing PFKP allowing cancer cell survival under metabolic stress
Dynamic regulation of glucose flux between aerobic glycolysis and the pentose phosphate pathway (PPP) during epithelial-mesenchymal transition (EMT) is not well-understood. Here we show that Snail (SNAI1), a key transcriptional repressor of EMT, regulates glucose flux toward PPP, allowing cancer cel...

MetabolomicsSystem Xc- exacerbates metabolic stress under glucose depletion in oral squamous cell carcinoma

OBJECTIVE: Emerging evidence suggests that glucose depletion (GD)-induced cell death depends on system Xc-, a glutamate/cystine antiporter extensively studied in ferroptosis. However, the underlying mechanism remains debated. Our study confirmed the correlation between system Xc...

MetabolomicsER stress inhibits liver fatty acid oxidation while unmitigated stress leads to anorexia-induced lipolysis and both liver and kidney steatosis
The unfolded protein response (UPR), induced by endoplasmic reticulum (ER) stress, regulates the expression of factors that restore protein folding homeostasis. However, in the liver and kidney, ER stress also leads to lipid accumulation, accompanied at least in the liver by transcriptional suppress...

MetabolomicsProteomics and metabolomics analysis based on exosomes revealed the response mechanism of Alicyclobacillus acidoterrestris to acid stress

Bacteria secrete exosomes containing stress-related molecules such as proteins and nucleic acids, which facilitate adaptation to challenging environments. In order to elucidate the role of A. acidoterrestris exosomes in its acid stress response, this study combined proteomics and metabolomics to ...
