MAPL regulates gasdermin-mediated release of mtDNA from lysosomes to drive pyroptotic cell death
Mitochondrial control of cell death is of central importance to disease mechanisms from cancer to neurodegeneration. Mitochondrial anchored protein ligase (MAPL) is an outer mitochondrial membrane small ubiquitin-like modifier ligase that is a key determinant of cell survival, yet how MAPL controls the fate of this process remains unclear. Combining genome-wide functional genetic screening and cell biological approaches, we found that MAPL induces pyroptosis through an inflammatory pathway...
The interactome era: Integrating RNA-seq, proteomics, and network biology to decode cellular senescence
Cellular senescence is a dynamic state in which cells permanently withdraw from the cell cycle while continuing to reshape their internal and external environment. It is characterized by persistent DNA damage responses, chromatin reorganization, and the secretion of a complex mixture of cytokines and proteases collectively known as the senescence-associated secretory phenotype (SASP). Transcriptomic and proteomic studies have defined key markers, including CDKN2A, CDKN1A, TP53, and SASP factors,...
Effects of lifetime supplementation with ubiquinol 10 on the lifespan and progression of aging in female C57BL/6 mice
Supplementation with ubiquinol 10 has been shown to improve the health of experimental animals and elderly individuals. The present study investigated the effects of lifetime supplementation with ubiquinol 10 on the progression of aging and lifespan in C57BL/6 mice, a standard strain for biomedical and aging research. A diet containing ubiquinol 10 (0.3 % w/w) and a control diet were fed to female C57BL/6J mice from 8 weeks of age until death, and the progression of senescence, lifespan, and...

Sex differences in healthy brain aging are unlikely to explain higher Alzheimer's disease prevalence in women
As Alzheimer's disease (AD) is diagnosed more frequently in women, understanding the role of sex has become a key priority in AD research. However, despite aging being the primary risk factor for AD, it remains unclear whether men and women differ in the extent of brain decline with age. Using 12,638 longitudinal brain MRIs from 4,726 participants aged 17 to 95 y across 14 cohorts, we examined sex differences in structural brain changes over time, controlling for differences in head size. Men...
