Mitochondrial filaments and clusters as intracellular power-transmitting cables

Skulachev, Vladimir P.·2001·Trends in Biochemical Sciences

Abstract

Mitochondria exist in two interconverting forms; as small isolated particles, and as extended filaments, networks or clusters connected with intermitochondrial junctions. Extended mitochondria can represent electrically united systems, which can facilitate energy delivery from the cell periphery to the cell core and organize antioxidant defence of the cell interior when O2 is consumed by mitochondrial clusters near the the outer cell membrane, and protonic potential is transmitted to the cell core mitochondria to form ATP. As to small mitochondria, they might represent a transportable form of these organelles.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • This operation is unique to myotubes; previous reports on cardiac myocytes or fibroblasts suggest there are several independent clusters of electrically connected mitochondria per cell.

  • Mitochondrial fusion enables redistribution of energy in the form of mitochondrial potential, metabolites, proteins, and mtDNA, improving calcium handling and ATP synthesis.

    “This process enables the redistribution of energy in the form of mitochondrial potential, metabolites, proteins, and mtDNA, improving calcium handling, and ATP synthesis [24, 54–57].”
  • In healthy cells, mitochondrial fusion provides a synchronized internal cable for translocating metabolites and intramitochondrial mixing during biogenesis, whereas mitochondrial division facilitates the equal distribution of mitochondria into daughter cells during mitosis and allows the selective degradation of damaged mitochondria through autophagy.

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.
