Cellular senescence
Cellular senescence is a stable cell-state program in which cells undergo essentially irreversible growth arrest while remaining metabolically active.
Cellular senescence is a stable cell-state program in which cells undergo essentially irreversible growth arrest while remaining metabolically active. It is widely recognized as a hallmark of aging and a contributor to age-related tissue dysfunction, but it also appears in diverse contexts such as oxidative stress, DNA damage, oncogenic signaling, radiotherapy, metabolic disease, and chronic inflammation. Senescent cells often develop a senescence-associated secretory phenotype (SASP), characterized by the release of proinflammatory cytokines, growth factors, and other mediators that can reshape the tissue microenvironment.
Biologically, cellular senescence has a dual role. It can act as a tumor-suppressive mechanism by preventing the proliferation of damaged cells, yet persistent senescent cells can promote tissue injury, fibrosis, immune dysregulation, and disease progression. Recent work has linked senescence to mitochondrial dysfunction, mitophagy defects, TP53 signaling, Wnt/β-catenin pathway changes, FOXO1-related geroprotective pathways, and inflammatory remodeling in tissues such as skin, kidney, lung, bone, lens, and reproductive organs.

Ageing, senescence and age-associated disease are the loose threads linking this otherwise heterogeneous set. Individual studies address Wnt-mediated reversal of dental stem-cell senescence, SIRT1 control of L1 retrotransposons, uPAR-targeted nanoparticles, and senolytic compounds for pulmonary fibrosis. Others focus on epigenetic clocks, biological-age markers, frailty, neurodegeneration and SPP1. The collection supports no shared therapeutic direction or unified research trajectory.
SIRT1 links cellular senescence to L1 retrotransposon control
SIRT1-mediated regulation of L1 retrotransposons in senescent cells shows that cellular senescence can function through derepression of mobile genetic elements, rather than only as a state to reverse, eliminate, or associate with disease. The study found that SIRT1 stabilizes Lamin B1–KAP1 heterochromatin complexes at the L1 5′-UTR, increases H3K9me3, suppresses L1 transcription and retrotransposition, and thereby maintains genomic stability and delays senescence; SIRT1 deficiency had the opposite effects. This places retrotransposon silencing and the resulting type-I interferon response within the senescence mechanism itself, opening a distinct direction focused on genome regulation rather than senescent-cell removal or tissue-specific senescence phenotypes 42669067Aug.
