  • Sphingolipids are a heterogeneous group of lipids with important roles in membrane form and function, cell signalling, and development. This Review discusses the regulation of sphingolipid metabolism at the subcellular and organismal levels and explores the therapeutic potential of targeting sphingolipids in human diseases.

  • Endosomes function as sorting stations that segregate cargo proteins into endosomal carriers, enabling their distribution to subcellular target compartments. Increasingly detailed structural insights have revealed how proteins, such as sorting nexins, assemble on endosomal membranes to form a coat that facilitates the formation and detachment of tubular carriers.

  • Kawaguchi et al. identify a chromatin code based on repressive histone 3 lysine 27 trimethylation (H3K27me3) that serves as a segment-specific positional marker in connective tissue cells of axolotls, enabling correct patterning during limb regeneration.

  • Senescent cells have complex and important roles in cancer and ageing, but they are quite rare and difficult to characterize in tissues in vivo. In this Expert Recommendation, the SenNet Biomarkers Working Group discusses recent advances in detecting and characterizing cellular senescence and provides recommendations for senescence markers in 14 human and mouse tissues.

  • Biomolecular condensates are emerging as hubs of splicing regulation. This Review discusses the modulation of condensate functions through alternative splicing, regulation of (co-transcriptional) splicing at condensates and the involvement of these condensates in human diseases.

  • Verheyen and Gottardi revisit two seminal papers by the Basler, Peifer and Clevers labs elucidating the role of nuclear β-catenin in Wnt signal transduction through its interaction with TCF at Wnt target genes.

  • Oxidation–reduction (redox) reactions involving reactive oxygen, nitrogen and sulfur species are vital for life, but excessive oxidant levels contribute to ageing and diseases. This Review explores cellular dynamics of redox homeostasis, such as responses to oxidative and reductive stresses and intracellular and intercellular redox communication pathways.

  • During embryonic epithelial–mesenchymal transition, epithelial cells undergo substantial phenotypic changes and acquire migration capacity. This Review compares embryonic and adult non-cancer EMTs and discusses the role of EMTs in adult tissue repair and fibrosis, highlighting therapeutic opportunities to modulate EMT to reduce fibrosis and promote repair.
