Taking a good look at free radicals in the aging process
Open accessAbstract
The mitochondrial free radical theory of aging (MFRTA) proposes that aging is caused by damage to macromolecules by mitochondrial reactive oxygen species (ROS). This is based on the observed association of the rate of aging and the aged phenotype with the generation of ROS and oxidative damage. However, recent findings, in particular in Caenorhabditis elegans but also in rodents, suggest that ROS generation is not the primary or initial cause of aging. Here, we propose that ROS are tightly associated with aging because they play a role in mediating a stress response to age-dependent damage. This could generate the observed correlation between aging and ROS without implying that ROS damage is the earliest trigger or main cause of aging.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
In the citing paper
“As chronological age advances, the levels of ROS increase in an attempt to maintain survival until they betray their original purpose and eventually aggravate, rather than alleviate, the age-associated damage”
From The Hallmarks of Aging (2013) · cites this paper as Hekimi et al., 2011
In the citing paper
“In this theory, high levels of ROS promote mtDNA damage and the aged phenotype, while low levels of ROS are signaling molecules that regulate stress response pathways and activate cellular processes that enhance lifespan (Hekimi et al., 2011).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
