Abstract

Cytokines such as interleukin-6 induce tyrosine and serine phosphorylation of Stat3 that results in activation of Stat3-responsive genes. We provide evidence that Stat3 is present in the mitochondria of cultured cells and primary tissues, including the liver and heart. In Stat3 –/– cells, the activities of complexes I and II of the electron transport chain (ETC) were significantly decreased. We identified Stat3 mutants that selectively restored the protein's function as a transcription factor or its functions within the ETC. In mice that do not express Stat3 in the heart, there were also selective defects in the activities of complexes I and II of the ETC. These data indicate that Stat3 is required for optimal function of the ETC, which may allow it to orchestrate responses to cellular homeostasis.

  • STAT3 can directly regulate mitochondrial function, and Nox2 can modulate mitochondrial activity.

    “STAT3 can directly regulate mitochondrial function [97,98], and Nox2 can modulate mitochondrial activity [99][100][101]”

    From Parvalbumin interneuron vulnerability and brain disorders (2021) · cites this paper as [98]

  • STAT3 has a specific role in modulating mitochondrial function through mechanisms independent of its nuclear factor function but dependent on phosphorylation at a serine residue.

    “STAT3, initially characterized as a nuclear factor that regulates gene expression in response to IL-6 and other cytokines, has been recently found to have a specific role in modulating mitochondrial function through mechanisms independent of its function as a nuclear factor, but dependent on its phosphorylation at a serine residue (412, 445).”

    From Redox regulation of mitochondrial function (2012) · cites this paper as [445]

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.
