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...

MetabolomicsCell type-specific proteomics uncovers a RAF15-SnRK2.6/OST1 kinase cascade in guard cells

Multicellular organisms such as plants contain various cell types with specialized functions. Analyzing the characteristics of each cell type reveals specific cell functions and enhances our understanding of organization and function at the organismal level. Guard cells (GCs) are specialized epid...

MetabolomicsCroquemort elicits activation of the immune deficiency pathway in ticks
The immune deficiency (IMD) pathway directs host defense in arthropods upon bacterial infection. In Pancrustacea, peptidoglycan recognition proteins sense microbial moieties and initiate nuclear factor-κB-driven immune responses. Proteins that elicit the IMD pathway in non-insect arthropods remain e...

MetabolomicsAMPK activation induces RALDH+ tolerogenic dendritic cells by rewiring glucose and lipid metabolism.
Dendritic cell (DC) activation and function are underpinned by profound changes in cellular metabolism. Several studies indicate that the ability of DCs to promote tolerance is dependent on catabolic metabolism. Yet the contribution of AMP-activated kinase (AMPK), a central energy sensor promoting c...

MetabolomicsThe ULK3 kinase is a key determinant of keratinocyte self-renewal and tumorigenesis targeting the arginine methylome
Epigenetic mechanisms oversee epidermal homeostasis and oncogenesis. The identification of kinases controlling these processes has direct therapeutic implications. We show that ULK3 is a nuclear kinase with elevated expression levels in squamous cell carcinomas (SCCs) arising in multiple body sites,...

MetabolomicsPFKFB3-mediated glycolysis boosts fibroblast activation and subsequent kidney fibrosis

Renal fibrosis, a hallmark of chronic kidney diseases, is driven by the activation of renal fibroblasts. Recent studies have highlighted the role of glycolysis in this process. Nevertheless, one critical glycolytic activator, 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3), remain...

MetabolomicsBacterial Pathogens Hijack the Innate Immune Response by Activation of the Reverse Transsulfuration Pathway

The reverse transsulfuration pathway is the major route for the metabolism of sulfur-containing amino acids. The role of this metabolic pathway in macrophage response and function is unknown. We show that the enzyme cystathionine γ-lyase (CTH) is induced in macrophages infected with pathogenic ba...

MetabolomicsPhosphoethanolamine Cytidylyltransferase 2 Integrates DAG Metabolism and TBK1 Activation to Regulate Antiviral Innate Immunity

Phosphatidylethanolamine (PE) biosynthesis is critical for membrane biology and cellular homeostasis. However, its specific role in antiviral innate immunity remains poorly understood. Here, we demonstrate that inhibition of phosphoethanolamine cytidylyltransferase 2 (PCYT2), a key enzyme in...

MetabolomicsBisphenol mixture-induced DGKB downregulation promotes premature human neurogenesis through the activation of MAPK pathway

The widespread industrial transition from bisphenol A (BPA) to structural analogs such as BPS, BPE, and BPAF has raised significant concerns regarding their potential health risks. However, their neurodevelopmental risks and underlying molecular mechanisms, particularly when present as complex m...

MetabolomicsAMPK activation orchestrated replicative senescence of periodontal ligament stem cells via regulating metabolomics

BACKGROUND: Periodontal ligament mesenchymal stem cells (PDLSCs) are a promising cell resource for cell-based regenerative medicine in dentistry. PDLSCs inevitably acquire a senescent phenotype after prolonged in vitro expansion, and the key regulators of cells during replicative...
