Transcriptional Activation by Tetracyclines in Mammalian Cells

Gossen, Manfred, Freundlieb, Sabine, Bender, Gabriele, Müller, Gerhard, Hillen, Wolfgang, Bujard, Hermann·1995·Science

Abstract

A transcriptional transactivator was developed that fuses the VP16 activation domain with a mutant Tet repressor from Escherichia coli. This transactivator requires certain tetracycline (Tc) derivatives for specific DNA binding. Thus, addition of doxycycline to HeLa cells that constitutively synthesized the transactivator and that contained an appropriate, stably integrated reporter unit rapidly induced gene expression more than a thousandfold. The specificity of the Tet repressor-operator-effector interaction and the pharmacological characteristics of Tc's make this regulatory system well suited for the control of gene activities in vivo, such as in transgenic animals and possibly in gene therapy.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • The Tet-On system allows activation of gene expression by the addition of dox.

    “In 1995, Gossen et al. developed the Tet-On system (Fig. 1C), a regulatory system that allows activation of gene expression by the addition - instead of removal - of dox [12].”

    From Tet-On Systems For Doxycycline-inducible Gene Expression (2016) · cites this paper as [12]

  • The reverse-TetR (rTetR) differed at four amino acid positions from the original TetR, and fusion of the VP16 activation domain resulted in rtTA that binds Ptet and activates transcription exclusively in the presence of dox.

    “This reverse-TetR (rTetR) differed at four amino acid positions from the original protein (Fig. 2).”

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.
