NFKB1 and glioblastoma: Compared with cells treated with DMSO only and cells treated with X-ray irradiation only, cells treated with NVP-BEP800 and X-ray irradiation had significantly lower expression levels of IKKβ protein NVP-BEP800 and X-ray irradiation may inhibit the proliferation of glioblastoma cells through a mechanism associated with the NF-κB signaling pathway.
