Plasma membrane damage limits replicative lifespan in yeast and induces premature senescence in human fibroblasts

Abstract excerpt

Abstract Plasma membrane damage (PMD) occurs in all cell types due to environmental perturbation and cell-autonomous activities. However, cellular outcomes of PMD remain largely unknown except for recovery or death. In this study, using budding yeast and normal human fibroblasts, we found that cellular senescence—stable cell cycle arrest contributing to organismal aging—is the long-term outcome of PMD. Our...
