The mTOR protein kinase forms two multiprotein complexes, mTORC1 and mTORC2, that function in distinct signaling pathways. mTORC1 is regulated by nutrients, and mTORC2 is a central node in phosphoinos...

This study positions intermediate filaments (IFs) as functional drivers and molecular markers of glioblastoma invasion. van Bodegraven et al. reveal that vimentin expression correlates with pro-invasive markers in patients. They show that while IFs reduce glioblastoma cell deformability, they promote matrix degradation via MMP14 expression, which facilitates 3D invasion.

Nature Structural & Molecular Biology, Published online: 27 November 2025; doi:10.1038/s41594-025-01720-4Cells store excess fat in lipid droplets to avoid lipotoxicity and maintain homeostasis. We identified an autophagy-independent role for the autophagy lipid transfer protein ATG2A in helping direct lipids to growing lipid droplets and promoting recruitment of the enzyme DGAT2. This coordination enhances triglyceride storage, protects the endoplasmic reticulum from lipid overload and limits the misrouting of lipids into other metabolic pathways.

Under stress, cells adapt their gene expression programs through changes in transcription and translation. It is unclear how cells determine which mRNAs are translated or repressed. Zedan et al. show that the timing of mRNA production alone determines the selectivity of translation, thereby coupling the processes of transcription and translation.
