🧪 Overview
The Senescence-Associated Epigenetic Phenotype (SEP) is hypothesized to contribute to neurodegeneration, potentially acting as a driver of disease progression. However, recent reappraisals of accelerated aging in neurodegeneration caution that aging signatures may be correlative and conceptually overextended rather than causal drivers (PMID:37887295). In addition, cellular models of aging and senescence exhibit substantial model-dependence, limiting direct inference from a senescence‑associated epigenetic phenotype to human neurodegeneration (PMID:40862757).

IF senolytic therapy (dasatinib 100mg + quercetin 1000mg, daily for 3 consecutive days per month for 12 months) is administered to early-stage Alzheimer's disease patients, THEN measurable reduction in plasma SASP factors (IL-6, IL-8, TNF-α) by ≥30% and deceleration of epigenetic age acceleration (H
Predicted outcome: ≥30% reduction in composite SASP score and epigenetic age deceleration of ≥1 year compared to placebo group

IF human iPSC-derived cortical neurons are subjected to radiation-induced senescence (10 Gy gamma irradiation) and subsequently treated with epigenetic editing (HDAC inhibitor valproic acid 1mM for 7 days), THEN genome-wide DNA methylation profiling should reveal reversion of ≥20% of differentially
Predicted outcome: ≥20% reversion of radiation-induced DMPs in senescence pathways after HDAC inhibition
Falsification: Fewer than 10% of DMPs revert toward baseline, or reversion occurs in non-senescence pathways only, indicating off-target effects rather than SEP reversal
