Activity-Dependent Neuroprotective Protein Modulates Its Own Gene Expression

Abstract

We investigated whether activity-dependent neuroprotective protein (ADNP) could autoregulate its own expression. Both the endogenous ADNP gene and reporter gene constructs were analysed in response to overexpression of ADNP, supplied either as wild-type ADNP or a mutant form lacking the NAP motif, a motif which has neuroprotective properties. Overexpression of these two forms of ADNP resulted in both decreased endogenous ADNP expression and repressed ADNP promoter-directed reporter gene activity. Chromatin immunoprecipitation demonstrated the ability of ADNP to bind to its own promoter which is consistent with its action as a repressor of both promoter-supported and endogenous ADNP expression.

Statistics

Recomputing p-values needs the paper’s full text.

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?

  • Because ADNP expression is controlled by an autoregulatory negative feedback loop, the overall upregulation might result from the mutant protein's inability to bind the ADNP promoter.

    “Since ADNP expression is under control of an autoregulatory negative feedback loop33, the overall upregulation might be a consequence of the inability of the mutant protein to bind the ADNP promoter.”

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.
