Functional analysis of an oxygen-regulated transcriptional enhancer lying 3' to the mouse erythropoietin gene.
Open accessAbstract
Erythropoietin, the major hormone controlling red-cell production, is regulated in part through oxygen-dependent changes in the rate of transcription of its gene. Using transient transfection in HepG2 cells, we have defined a DNA sequence, located 120 base pairs 3' to the poly(A)-addition site of the mouse erythropoietin gene, that confers oxygen-regulated expression on a variety of heterologous promoters. The sequence has the typical features of a eukaryotic enhancer. Approximately 70 base pairs are necessary for full activity, but reiteration restores activity to shorter inactive sequences. This enhancer operates in HepG2 and Hep3B cells, but not in Chinese hamster ovary cells or mouse erythroleukemia cells, and responds to cobalt but not to cyanide or 2-deoxyglucose, thus reflecting the physiological control of erythropoietin production accurately.

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.
