This Review discusses the role of phosphatidylinositol phosphates and their modifying enzymes in modulating cell motility and adhesion and emphasizes the potential of targeting the associated pathways for therapeutic benefit.

Lysosomal dysfunction is emerging as a common pathogenic mechanism underlying normal ageing and many age-related diseases. Lysohormesis, the triggering of beneficial adaptations by mild lysosomal stress leading to increased lysosomal function and cellular stress resilience, could provide a common solution to many age-related issues.

This Review discusses the recent advances in experimental approaches to interrogate the mechanical forces that mediate tissue deformations during development, highlighting the insights afforded at both the cellular and tissue scales.

Auwerx and colleagues review recent advances in mitochondrial genetics, proteomics and biochemistry that emphasize the far-reaching impact of mitochondrial genetic variation and the role of mitochondria as finely tuned signalling hubs.

Petropoulos and colleagues perform single-cell transcriptomics, spatial, functional and comparative analyses, and show that the guinea pig presents high similarity with early human embryogenesis.

Stamatov et al. introduce Facilitated Segmentation and Tracking of Chromosomes in Mitosis Pipeline (FAST CHIMP), which combines time-lapse super-resolution microscopy with deep learning to study chromatin dynamics in live cells.

Rettkowski, Romero-Mulero et al. show that myocardial infarction impacts bone marrow haematopoietic stem cells and leads to inflammatory myelopoiesis, which can be dampened by treatment with 4-oxo-retinoic acid, promoting cardiac recovery.

Chou et al. generate transdifferentiated human neurons from fibroblasts from young or aged individuals and patients with Alzheimer’s disease. Studies of endolysosomes and proteostasis suggest a role for lysosomal quality control in Alzheimer’s disease pathology.

Lange, Ratz, et al. investigate the number and distribution of human prohibitin complexes in the mitochondrial inner membrane, uncovering their bell-shaped structure and assembly of alternating PHB1 and PHB2 molecules.

Sun et al. identify a role for PABPC1 in selectively regulating the translation of leukaemogenic mRNAs to promote blast crisis transition, which may be targeted to overcome resistance to TKI treatment in chronic myeloid leukaemia.

Lysosomal dysfunction is emerging as a common pathogenic mechanism underlying normal ageing and many age-related diseases. Lysohormesis, the triggering of beneficial adaptations by mild lysosomal stress leading to increased lysosomal function and cellular stress resilience, could provide a common solution to many age-related issues.
