Monoallelic Deletion of NFKBIA in Glioblastoma: When Less Is More

Bredel et al. (2010) recently identified a subset of glioblastomas that harbor monoallelic loss of NFKBIA, which negatively affects patient prognosis. This finding raises new questions as to the role of IκBα and NF-κB in glioblastoma, the relationship between EGFR and NF-κB signaling, and potential therapeutic targets.
