Abstract

Mitochondria are highly dynamic, maternally inherited cytoplasmic organelles, which fulfill cellular energy demand through the oxidative phosphorylation system. Besides, they play an active role in calcium and damage‐associated molecular patterns signaling, amino acid, and lipid metabolism, and apoptosis. Thus, the maintenance of mitochondrial integrity and homeostasis is extremely critical, which is achieved through continual fusion and fission. Mitochondrial fusion allows the transfer of gene products between mitochondria for optimal functioning, especially under metabolic and environmental stress. On the other hand, fission is crucial for mitochondrial division and quality control. The imbalance between these two processes is associated with various ailments such as cancer, neurodegenerative and cardiovascular diseases. This review discusses the molecular mechanisms that control mitochondrial fusion and fission and how the disruption of mitochondrial dynamics manifests into various disease conditions.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Oxidative stress leads to oxidative damage to biomolecules, especially DNA, causing endogenous damage-associated molecular patterns production and cytokine release.

    “Oxidative stress leads to oxidative damage to biomolecules (especially DNA),201 causing endogenous damage-associated molecular patterns (DAMPs) production and cytokine release in the organism.202,203”

    From Inflammation and aging: signaling pathways and intervention therapies (2023) · cites this paper as [203]

    The Introduction’s Carcinogenesis section says HMGB1 is released following cell death, injury, or stress, which supports the release of an endogenous damage signal. It does not connect oxidative stress to DAMP production or report the claimed cytokine release; the oxidative-damage clause is separately cited to reference 201. (LLM, conf=0.76)

  • Cytokines activate downstream signaling pathways of pattern recognition receptors, causing systemic chronic inflammatory responses in the body.

    “Cytokines activate downstream signaling pathways of pattern recognition receptors,203 causing systemic chronic inflammatory responses in the body.204”

    From Inflammation and aging: signaling pathways and intervention therapies (2023) · cites this paper as [203]

    Citation 204 is attached to the claim about systemic chronic inflammatory responses. The Introduction > Carcinogenesis discusses HMGB1–RAGE signaling in tumors, and Introduction > Atherosclerosis describes a chronic vascular disease, but neither passage says that cytokine signaling causes systemic chronic inflammation. Searches for systemic chronic inflammatory responses and pattern-recognition-receptor cytokine signaling found no supporting passage; page numbers were not available in our copy. (LLM, conf=0.74)

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.
