p110α inhibitors decrease the viability of neuroblastoma cells. a The specificity of different PI3K inhibitors. Information was collected from Selleckchem (https://www.selleckchem.com/PI3K.html). b–f Cell viabilities of different neuroblastoma cells were determined by CellTiter-Glo® Luminescent Cell Viability Assay upon treating with various PI3K inhibitors at different doses for 72 h. 10 μg/ml puromycin was applied for no-survival controls. All values were normalized to the vehicle (maxi) and no-survival control (min) before illustrating the inhibition curves with GraphPad Prism (“Materials and methods” section). Data were presented as the mean ± SD
