Abstract

We have identified in mouse hepatoma cells a third cis-acting dioxin-responsive element (DRE) within the 5' flanking region of the cytochrome P1-450 gene, which is transcriptionally activated by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). The DRE can activate a heterologous promoter and functions in either orientation; therefore, it has the properties of a transcriptional enhancer. The DRE fails to activate transcription in receptor-defective cells; therefore, it requires TCDD-receptor complexes for its function. By using a gel retardation assay, we show that nuclear extracts contain a protein that binds to the DRE in TCDD-inducible, receptor-dependent, and DNA sequence-specific fashion. The protein-DNA interaction occurs within 10 min of exposure of the cell to TCDD and does not require ongoing protein synthesis. Our results imply that the TCDD-receptor complex interacts specifically with the DRE and demonstrate a relationship between protein-DNA interaction in vitro and function in vivo. Our findings also suggest that the affinity of the TCDD-receptor complex for the DRE may be relatively high in comparison to analogous protein-DNA interactions at other inducible enhancers.

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.
