Intermediate filaments promote glioblastoma cell invasion by controlling nuclear deformations and mechanosensitive expression of MMP14
Intermediate filaments promote glioblastoma cell invasion by controlling nuclear deformations and mechanosensitive expression of MMP14
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: 26 November 2025; doi:10.1038/s41594-025-01716-0Rocha-Roa et al. identify TMEM170 proteins as endoplasmic reticulum lipid scramblases that partner with bridge-like lipid transfer proteins BLTP1/Csf1 proteins to enable bulk lipid transport between organelles.

Online Now: Timing of transcription controls the selective translation of newly synthesized mRNAs during acute environmental stress Online now:
Timing of transcription controls the selective translation of newly synthesized mRNAs during acute environmental stress
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.

Nice paper from @leventallab.bsky.social suggess lipid-driven domains organise cargo and trafficking machinery at ERES to sort and export transmembrane proteins.
ER exit sites mediated by the COPII adaptor sec24D selectively recruit lipid raft-preferring proteins for rapid ER export.

EMBL Grenoble scientists filmed a self-splicing ribozyme folding into a functional machine – frame by frame.

Using cryo-EM, SAXS & simulations, they revealed the choreography that keeps it from misfolding. This discovery could help train AI for RNA structure prediction.

Online Now: Recycling of ribosomes at stop codons drives the rate of translation and the transition from proliferation to RESt Online now:
Recycling of ribosomes at stop codons drives the rate of translation and the transition from proliferation to RESt
Ribosome recycling’s role in translational regulation remains unclear. Miluzio, Scagliola, et al. show that blocking eIF6 phosphorylation by environmental stressors delays ribosome recycling at stop codons, leading to translational reprogramming and establishing RESt. RESt is reversible, characterized by metabolic remodeling, low translation, reduced reinitiation, and NF-κB pathway activation.

Exciting new findings: Wnt-receptor endocytosis is required for canonical Wnt activation, yet uptake mechanisms has been controversial. We resolve this by showing that Wnt3a triggers rapid Clathrin- and Fast Endophilin-Mediated LRP6 endocytosis at low concentrations sufficient for Wnt activation.
The Actin regulator Mena promotes Wnt signalosome endocytosis and Wnt signalling
Wnt signaling controls embryonic development and tissue maintenance. Endocytosis of Wnt-receptors is required for signalling, yet uptake mechanisms remain poorly understood. Here, we identify the acti...
