(A) Growth status of U251 cells. As the concentration of GA increases, the survival state of the U251 cell line gradually deteriorates. (B) Cell viability of U251 cells. After different concentrations of GA were incubated with U251 cells, cell viability of each group was detected by the CCK-8 reagent. When the GA concentration is 1.5 μmol/L, the cell viability is 56.99 ± 3.95% (**p < 0.01 versus “0 μmol/L” group).
