29Brain cells organize into distinct DNA repair niches during mouse aging
Spatial transcriptomics shows neuronal and vascular DNA damage responses correspond to distinct local cell neighborhoods in aging brains.
Aging impairs blastema formation and tissue regeneration in Cladonema jellyfish
Older jellyfish medusae exhibit cell loss, heightened DNA damage, and defective wound closure that limit complex tentacle regrowth.
Inhibiting CHK2 improves oocyte quality and reduces ovarian inflammation in aged mice
A multi-omic analysis shows that defective luteal resolution and CHK2-driven inflammation drive ovarian aging, but drug inhibition restores oocyte maturation.
Nucleoli buffer displaced heterochromatin to limit premature aging programs in cells
In cells expressing progerin, the nucleolus sequesters released lamina-associated domains to preserve gene repression and prevent worsening DNA damage.
Hybrid extracellular vesicles protect mouse skin from ultraviolet B photoaging
Vesicles fused from M2 macrophages and keratinocytes reduced oxidative stress, inflammation, and collagen degradation through the IL-4Rα/JAK/STAT3 pathway.
Base editing of the lamin farnesylation motif rescues progeria phenotypes in organoids
Lipid nanoparticle delivery of base-editing mRNA restored DNA repair and heterochromatin structure in human neuromuscular models of premature aging.
Syringin reduces cellular senescence and pulmonary fibrosis in mice and cell models
Computational screening identified the natural compound, which interacts with CHK1 to blunt replication stress and fibrotic signaling.
Chelating intracellular calcium reduces fibroblast senescence and eases lung fibrosis
Treating cells and an in vivo fibrosis model with a calcium chelator delayed senescence markers, reduced collagen buildup, and dampened inflammatory secretions.
Restoring HIRA chromatin maintenance improves aged mouse oocyte quality
Preventing HIRA SUMOylation rescues histone replacement, restoring chromatin integrity and developmental potential in aging mouse eggs.
