Stem cell control in the lung by an autocrine injury-activated Igf complex Science 16 Apr 2026 Vol 392, Issue 67 Structured Abstract INTRODUCTION Adult stem cells are rapidly, but transiently, activated by injury to repair damaged tissue. Repeated or chronic injury predisposes to cancer. Although there has been progress in identifying and characterizing mammalian stem cells and homeostatic mitogens that regulate their proliferation, injury-activated mitogens, the mechanisms t

Cell-type resolved protein atlas of brain lysosomes identifies SLC45A1-associated disease as a lysosomal disorder Cell Volume 189, Issue 3 p765-782.e31February 05, 2026 Highlights • Lysosomal proteomics of brain cell types • Identification of previously uncharacterized and cell-type-specific lysosomal proteins • SLC45A1 is a neuron-specific lysosomal sugar transporter • SLC45A1 loss drives lysosomal and mitochondrial dysfunction Summary Mutations in lysosomal genes cause neur

Nature volume 650 , pages 951–960 (2026) Abstract Primary sensory neurons in dorsal root ganglia (DRG) have long axons and a high demand for mitochondria, and mitochondrial dysfunction has been implicated in peripheral neuropathy after diabetes and chemotherapy 1 , 2 . However, the mechanisms by which primary sensory neurons maintain their mitochondrial supply remain unclear. Satellite glial cells (SGCs) in DRG encircle sensory neurons and regulate neuronal activity and pain

Autophagolysosomal exocytosis inverts Src kinase onto the cell surface in cancer Science 12 Mar 2026 Vol 391, Issue 6790 ditor’s summary Discovering cell surface proteins that are specific to cancer cells and not normal cells can create opportunities for safer delivery of toxic drugs to tumors. Delaveris et al . identified a family of proteins that are delivered to the cell surface in cancer but not in healthy tissues (see the Perspective by Pfannenstein and Meyer). One such

Ageing promotes metastasis via activation of the integrated stress response Nature 11 March 2026 Abstract Lung cancer predominantly affects older individuals, yet how physiological ageing influences tumour evolution remains poorly understood 1 . Here we show that ageing reprograms the evolutionary trajectory of KRAS -driven lung adenocarcinoma, limiting primary tumour growth while promoting metastatic dissemination through epigenetic activation of the integrated stress respon

DNA-protein cross-links promote cGAS-STING–driven premature aging and embryonic lethality Structured Abstract INTRODUCTION DNA-protein cross-links (DPCs) are highly toxic lesions in which proteins become covalently attached to DNA, blocking essential processes such as replication and transcription. To maintain genome stability, cells rely on specialized repair mechanisms that remove DPCs. The protease SPRTN was the first enzyme identified to resolve these lesions by cleaving

A lysosomal requiem for glioblastoma cells Laura Merlet, Margaux Le Guyon, Julie Gavard Abstract Once viewed solely as degradative compartments, lysosomes shape cell fate through signaling, metabolism, and communication. In glioblastoma, their rewiring underlies plasticity, invasion, and resistance to therapies. This forum explores lysosomal dynamics in brain tumors and therapeutic strategies targeting lysosomal vulnerabilities, offering fresh perspectives for precision appro
