Boron concentrations after exposure of GBM cells to the tested compounds. (a) Cellular uptake of TMZB and BPA in U87MG; (b) cellular uptake of TMZB and BPA in U251; (c) cellular uptake of TMZB and BPA in HS683; (d) time-dependent cellular uptake of TMZB (1.91 mM) in HUV-EC and HS683 cells. Boron concentrations were measured using ICP-AES. Bars represent mean ± SE based on 3 biological repeats. The statistical comparisons between curves were carried out by use of the Wilcoxon signed rank test. “ns” stands for not significant. * p < 0.05, ** p < 0.01.
