Reduction of DNA Topoisomerase Top2 Reprograms the Epigenetic Landscape and Extends Health and Life Span Across Species

open access: yesAging Cell, Volume 24, Issue 6, June 2025.
This study demonstrates that reducing the enzyme topoisomerase Top2 or its mammalian homolog TOP2B promotes longevity across multiple species, including yeast, worms, and mice. At the cellular/molecular level, TOP2B reduction mitigates the major cellular aging hallmarks such as epigenetic alterations, cell senescence, lysosomal biogenesis, and ...

Compressive Forces Induce Epigenetic Activation of Aged Human Dermal Fibroblasts Through ERK Signaling Pathway

open access: yesAging Cell, Volume 24, Issue 6, June 2025.
Direct activation and rejuvenation of aged fibroblasts through the application of mechanical forces in a 3D spheroid culture model. The ERK signaling pathway was revealed as a key underlying mechanism. ABSTRACT Age‐related changes in human dermal fibroblasts (HDFs) contribute to impaired wound healing and skin aging.

Reorganization of H3K9me heterochromatin leads to neuronal impairment via the cascading destruction of the KDM3B-centered epigenomic network

open access: yesiScience
Summary: Histone H3K9 methylated heterochromatin silences repetitive non-coding sequences and lineage-specific genes during development, but how tissue-specific genes escape from heterochromatin in differentiated cells is unclear.

Age‐Dependent Regulation of Hippocampal Inflammation by the Mitochondrial Translocator Protein in Mice

open access: yesAging Cell, Volume 24, Issue 6, June 2025.
The role of mitochondrial translocator protein (TSPO) in hippocampal inflammation is age‐dependent, with TSPO deletion drastically exacerbating inflammation in aged mice, while dampening it in young mice. This TSPO–aging interaction was linked to NF‐kβ and interferon regulatory transcriptional networks. TSPO deletion exacerbated age‐dependent depletion
