Abstract Compartmentalization in living systems, where multiple reactions occur parallel within confined spaces, has inspired the development of droplet networks past decade. These fascinating assemblies offer unique and versatile functions that are unattainable by single droplets have shown their potential as advanced platforms for chemical biological applications. This review highlights recent progress creation application networks, covering strategies generating assembling them into functional networks. Key applications such microreactors, signal conductors, actuators, power sources summarized. We also discuss challenges future trends this field, aiming to narrow gap between fundamental research real

Mitochondria must maintain adequate amounts of metabolites for protective and biosynthetic functions. However, how mitochondria sense the abundance regulate metabolic homeostasis is not well understood. In this work, we focused on glutathione (GSH), a critical redox metabolite in mitochondria, identified feedback mechanism that controls its through mitochondrial GSH transporter, SLC25A39. Under physiological conditions, SLC25A39 rapidly degraded by protease AFG3L2. Depletion dissociates AFG3L2 from SLC25A39, causing compensatory increase uptake. Genetic proteomic analyses putative iron-sulfur cluster matrix-facing loop as essential regulation, coupling iron to import. Altogether, our work revealed paradigm autoregulatory control organelles.

The Golgi is a membrane-bound organelle that essential for protein and lipid biosynthesis. It represents central trafficking hub sorts proteins lipids to various destinations or secretion from the cell. has emerged as docking platform cellular signaling pathways including LRRK2 kinase whose deregulation leads Parkinson disease. dysfunction associated with broad spectrum of diseases cancer, neurodegeneration, cardiovascular diseases. To allow study at high resolution, we report rapid immunoprecipitation technique (Golgi-IP) isolate intact mini-stacks subsequent analysis their content. By fusing Golgi-resident TMEM115 three tandem HA epitopes (GolgiTAG), purified using Golgi-IP minimal contamination other compartments. We then established an pipeline liquid chromatography coupled mass spectrometry characterize human proteome, metabolome, lipidome. Subcellular proteomics confirmed known identified not previously Golgi. Metabolite profiling metabolome revealed enrichment uridine-diphosphate (UDP) sugars derivatives, which consistent roles in glycosylation. Furthermore, targeted metabolomics validated SLC35A2 subcellular transporter UDP-hexose. Finally, lipidomics showed phospholipids phosphatidylcholine, phosphatidylinositol, phosphatidylserine are most abundant glycosphingolipids enriched this compartment.

One-carbon metabolism is a central metabolic pathway critical for the biosynthesis of several amino acids, methyl group donors, and nucleotides. The mostly relies on transfer carbon unit from acid serine, through cofactor folate (in its forms), to ultimate acceptors that include nucleotides groups used methylation proteins, RNA, DNA. Nucleotides are required DNA replication, repair, gene expression, protein translation, ribosomal RNA. Therefore, one-carbon essential cell growth function in all cells, but specifically important rapidly proliferating cells. regulation aspect normal pathological pathway, such as cancer, where hijacking these regulatory mechanisms feeds an increased need regulated at levels: via posttranslational modification, subcellular compartmentalization, allosteric inhibition, feedback regulation. In this review, we aim inform readers relevant bring forward further study metabolism. review aims integrate two major aspects cancer metabolism-signaling downstream nutrient sensing metabolism, because while each proliferation cancerous their integration comprehensive understating cellular transformed cells can lead clinically insights.

Abstract Dysregulated macrophage responses and changes in tissue metabolism are hallmarks of chronic inflammation the skin. However, metabolic cues that direct support functions skin poorly understood. Here, we show during sterile inflammation, epidermis macrophages uniquely depend on glycolysis TCA cycle, respectively. This compartmentalisation is initiated by ROS-induced HIF-1α stabilization leading to enhanced epidermis. The end-product glycolysis, lactate, then exported epithelial cells utilized dermal induce their M2-like fates through NF-κB pathway activation. In addition, psoriatic disorder also driven such lactate metabolite-mediated crosstalk between macrophages. Notably, small-molecule inhibitors transport this setting attenuate psoriasis disease burden, suppress fate acquisition Our study identifies an essential role for metabolite regulating which may be effectively targeted treat inflammatory disorders as psoriasis.
