Abstract

We have characterized further the antioxidant responsive element (ARE) identified in the 5'-flanking region of the rat glutathione S-transferase Ya subunit gene and the NAD(P)H:quinone reductase gene by mutational and deletion analyses. Our data suggest that the sequence, 5'-puGTGACNNNGC-3' 3'-pyCACTGNNNCG-5' where N is any nucleotide, represents the core sequence of the ARE required for transcriptional activation by phenolic antioxidants and metabolizable planar aromatic compounds (e.g. beta-naphthoflavone and 3-methylcholanthrene). We also have found that the ARE is responsive to hydrogen peroxide and phenolic antioxidants that undergo redox cycling. These latter data suggest that the ARE is responsive to reactive oxygen species and thus may represent part of a signal transduction pathway that allow eukaryotic cells to sense and respond to oxidative stress.

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

  • The antioxidant response element (ARE) is a cis-acting enhancer sequence found within the promoter region of many cytoprotective antioxidant and phase II enzyme genes, with a core sequence of 5′-TGACnnnGC-3′.

    “The antioxidant response element (ARE) [42], also referred to as the electrophile response element (EpRE), is a cis-acting enhancer sequence found within the promoter region of many cytoprotective antioxidant and phase II enzyme genes. It has a core sequence of 5′-TGACnnnGC-3′ and participates in inducible gene expression in response to oxidative stress [42].”
  • H2O2-induced oxidative stress and PMA modulate the activity of IRP1 and IRP2.

    “H2O2-induced oxidative stress and phorbol 12-myristate 13-acetate (PMA) have been shown to modulate the activity of IRP1 and IRP2 (269).”
  • PMA induces IRP1 and IRP2 phosphorylation and enhances binding to ferritin IRE, resulting in decreased ferritin expression during PMA-induced HL-60 differentiation.

    “PMA induces IRP1 and IRP2 phosphorylation and enhances this binding to ferritin IRE, resulting in decreased ferritin expression during PMA induced HL-60 differentiation (269).”

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.
