Overexpression and RNA interference of Ap-cyclic AMP-response element binding protein-2, a repressor of long-term facilitation, in Aplysia kurodai sensory-to-motor synapses

Abstract

cyclic AMP-response element binding protein-2 (CREB2) is a member of the CREB/transcription factor (CREB/ATF4) family. CREB2 is a transcription factor known to be involved in Aplysia long-term facilitation. To further examine the role of ApCREB2 on long-term synaptic facilitation, we isolated ApCREB2 from Aplysia kurodai in full-length cDNA library, and found that the overexpression of ApCREB2 blocked 5-hydroxytryptamine (5-HT)-induced long-term synaptic facilitation in Aplysia sensory-to-motor synapses. Furthermore, a single pulse of 5-HT, which normally induces only short-term facilitation, in the presence of ApCREB2 inhibition by RNA interference, induced long-term facilitation in Aplysia sensory-to-motor synapses. These results suggest that ApCREB2 is a functional repressor of long-term facilitation in Aplysia sensory-to-motor synapses.

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.
