Fig 5. Effect of salicylates and glycyrrhizin on MNNG-induced cell death in HEK 293 cells.

Fig 5

(A) Concentration-dependent inhibition of MNNG-induced cell death by SA, B1 and FN2. (B) Concentration-dependent inhibition of MNNG-induced cell death by ac3AESA, 5-ASA and Gly. The anti-Parkinson’s drug deprenyl (Dep) served as a positive control. Cell death was evaluated 6 h after MNNG treatment by trypan blue staining. Data are mean ± SD (n = 6). Asterisks indicate the statistical significance difference compared to the MNNG-treated control (one-way analyses of variance (ANOVA) with post-hoc t test; * P<0.05).
