Abstract

We have identified two regions in the 5'-flanking sequence of the rat quinone reductase gene that contain xenobiotic responsive elements. The DNA sequence of the first region spans nucleotides -393 to -352 of the 5'-flanking region and shares sequence identity with the xenobiotic responsive element (XRE) described for the cytochrome P-450 CYPIA1 gene. The DNA sequence of the second region spans nucleotides -434 to -404 of the 5'-flanking region of the quinone reductase structural gene. When a synthetic oligonucleotide corresponding to nucleotides -434 to -404 was inserted in front of a heterologous promoter linked to the chloramphenicol acetyltransferase structural gene, an increase in basal level expression as well as responsiveness to beta-naphthoflavone and t-butylhydroquinone, but not 2,3,7,8-tetrachlorodibenzo-p-dioxin, was observed. The sequence, -434 to -404, did not have any sequence identity with the XRE but shared a large degree of identity with the antioxidant responsive element recently described for the rat glutathione S-transferase Ya subunit gene (Rushmore, T. H., King, R. G., Paulson, K. E., and Pickett, C. B. (1990) Proc. Natl. Acad. Sci. U. S. A. 87, 3826-3830; Rushmore, T. H., and Pickett, C. B. (1990) J. Biol. Chem. 265, 14648-14653). These results indicate that the antioxidant responsive element can be distinguished functionally from the classical XRE and is also involved in the regulation of the quinone reductase gene by planar aromatic compounds and phenolic antioxidants.

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.
