Figure 4From: Involvement of Akt/NF-κB pathway in antitumor effects of parthenolide on glioblastoma cells in vitro and in vivo In vitro angiogenesis assay. Glioblastoma cells were treated with parthenolide, and in vitro angiogenesis was assessed using a modified tube formation assay. (A) Representative tube formation data. (B) Tube formation was significantly suppressed by parthenolide in a dose-dependent manner. Data is presented as mean ± SD (n = 3). Points indicate bars + SD; * indicates p < 0.0001. Bar = 5 mm.Back to article page
