NF-κB transcription factor activity. NF-κB transcriptional activity was analysed in glioblastoma cells 48 h after treatment with parthenolide by using an ELISA-based assay. The assay showed that the transcriptional activity of NF-κB in the two glioblastoma cell lines decreased as the concentration of parthenolide increased. Data is presented as mean ± SD (n = 3). Points indicate bars + SD; * indicates p < 0.0001; ** indicates p < 0.01.
