Abstract

Small regulatory peptides encoded within the mitochondrial genome (mitochondrial derived peptides) have been shown to have cellular cyto- and metabolo-protective roles that parallel those of exercise. Here we provide evidence that humanin and SHLP6 are exercise-sensitive mitochondrial derived peptides. Studies to determine whether mitochondrial derived peptides play a role in regulating exercise-induced adaptations are warranted.

  • Exercise has been shown to increase the expression of Humanin and SHLP6, exerting anti-inflammatory, insulin-sensitizing, and metabolic regulatory effects.

    “In humans, exercise has been shown to increase the expression of Humanin and SHLP6, exerting anti-inflammatory, insulin-sensitizing, and metabolic regulatory effects [77,78].”

    From Exercise-Induced Myokines in Obesity-Related Metabolic Disorders and Cardiovascular Protection: A Narrative Review (2026) · cites this paper as [77]

    The Results and Discussion (page unavailable) report that acute exercise increased humanin abundance in muscle and plasma and appeared to raise plasma SHLP6 transiently in young men. They do not show that these exercise-induced changes exert anti-inflammatory, insulin-sensitizing, or metabolic-regulatory effects; the Introduction discusses insulin sensitivity following exogenous humanin treatment in rodents, and short-term training lowered rather than raised absolute plasma SHLP6.

  • Age may influence responses; some studies suggest that older adults show blunted irisin responses to training compared with younger populations.

    “Age may also influence responses; some studies suggest that older adults show blunted irisin responses to training compared with younger populations [40,77].”

    From Exercise-Induced Myokines in Obesity-Related Metabolic Disorders and Cardiovascular Protection: A Narrative Review (2026) · cites this paper as [77]

    The Discussion (page unavailable) compares exercise-related humanin findings in older men with those in a younger cohort, but it does not address irisin. Searches for irisin and age-related exercise responses found no passage reporting blunted irisin responses to training in older adults. (LLM, conf=0.77)

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.
