Paraneoplastic Encephalomyelitis Antigens Bind to the AU-rich Elements of mRNA

Liu, J., Dalmau, J., Szabo, A., Rosenfeld, M., Huber, J., Furneaux, H.·1995·Neurology

Abstract

The Hu antigens are composed of a family of neuronal-specific, RNA-binding proteins encoded by at least three distinct genes. All three gene products, HuD, HuC/ple21, and Hel-N1, are human homologues of Elav, a Drosophila protein required for neuronal development and maintenance. Although the three proteins are very similar in structure, they are differentiated by alternative splicing of their mRNAs. We report here that the Hu antigens bind avidly to the AU-rich element resident in many mRNAs that regulate cell proliferation. This interaction suggests that the Hu antigens promote neuronal differentiation by suppressing the neuroblast cell cycle. Such a mechanism provides a plausible model for the role of the Hu antigens in tumorigenesis, neuronal differentiation, and paraneoplastic neurologic disorders.

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.
