"Study indentifies NF-Yb as a novel transcriptional regulator of Gria4 (GluA4 gene) and a controller of excitotoxic death in the oligodendroglial lineage; describes a novel regulatory region within Gria4 containing CCAAT sequences whose binding by NF-Yb is regulated by excitotoxicity. Excitotoxicity-induced alterations in NF-Yb binding are associated with changes in Gria4 transcription."xsd:string
