Attenuation of ATM signaling by ROS delays replicative senescence at physiological oxygen.
Article in Molecular cell, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Replicative senescence is a powerful tumor suppressor pathway that curbs proliferation of human cells when a few critically-short telomeres activate the DNA damage response (DDR). We show that ATM is the sole DDR kinase responsible for the induction and maintenance of replicative senescence and that ATM inhibition can induce normal cell divisions in senescent cells. Compared to non-physiological atmospheric (∼20%) oxygen, primary fibroblast cells grown at physiological (3%) oxygen were more tolerant to critically short telomeres, explaining their extended replicative lifespan. We show that this tolerance is due to attenuation of the ATM response to double-strand breaks (DSBs) and unprotected telomeres. Our data indicate that the reduced ATM response to DSBs at 3% oxygen is due to increased ROS, which induces disulfide crosslinked ATM dimers that do not respond to DSBs. This regulation of cellular lifespan through attenuation of ATM at physiological oxygen has implications for tumor suppression through telomere shortening.
