MTT assay. Glioblastoma cells were treated with parthenolide, and cell proliferation was assessed using the MTT assay. Parthenolide inhibited the growth of glioblastoma cells at concentrations above 5 μM in a dose-dependent manner. Data is presented as mean ± SD (n = 3). Points indicate bars + SD; * indicates p < 0.0001.
