Abstract: AbstractThe induction of the immediate early gene Arc is strongly implicated in synaptic plasticity. Although the role of ERK was demonstrated, the regulation of Arc expression is largely unknown. In this study, we investigated the major signaling pathways underlying brain-derived neurotrophic factor (BDNF)-mediated Arc transcription in cultured cortical neurons. The BDNF-stimulated Arc transcription was solely regulated by the Ras-Raf-MAPK signaling through ERK, but not by phosphoinositide 3-kinase (PI3K) an…
