Values for untreated cells were taken as 100%. b BrdU incorporation test for cell proliferation of U-87 MG and LN18 cells after exposure to 1–5 for 24 h at indicated concentrations. The respective p values were calculated using type 2 two-tailed t test followed by FDR corrections for multiple hypothesis testing and p < 0.05 was considered statistically significant (n = 3)Back to article page
