Persistent rDNA Damage Triggers PML-Nucleolar Compartments
2026-09-24
Urbancokova, Hornofova and colleagues show that topological stress and RNA polymerase I inhibition can create persistent ribosomal DNA lesions associated with PML-nucleolar compartments (PNAs). Their experiments link these compartments to damaged rDNA and an incomplete homologous-recombination response, offering a framework for studying nucleolar genome maintenance and cellular senescence.

How Kinase Inhibitors Promote p38α Dephosphorylation
2026-09-23
The reference preprint shows that some kinase inhibitors do more than occupy the p38α active site: they reshape its activation loop so WIP1 can dephosphorylate the kinase more efficiently. This dual-action mechanism links inhibitor binding to phosphatase accessibility and suggests a structure-guided route toward more potent and selective p38 pathway modulation.

Dynamic Myelin Remodeling After CNS Damage
2026-09-18
A 2026 Science study shows that early CNS myelin damage often appears as swelling that can resolve or remodel rather than inevitably progressing to sheath loss. By linking activity-dependent pathology across zebrafish, rodent, and human MS tissue, the work identifies a potentially actionable window before irreversible demyelination.
