Effect of GA alone or after NAC pre-treatment on phosphorylation status of signal proteins p38 MAPK (a), Erk 1/2 (b) and Akt (c) in Hela cells. Data were obtained from three independent flow cytometry experiments after 1–72 h GA treatment. Significance: * P < 0.05, ** P < 0.01, *** P < 0.001 versus untreated cells (control); ⁺ P < 0.05, ⁺⁺ P < 0.01, ⁺⁺⁺ P < 0.001 versus GA
