Figure 3: Effects of (-)-linalool on SNP-induced cytotoxicity in SH-SY5Y cells. SH-SY5Y cells were incubated with 5 μM (-)-linalool for 24 h prior to treatment with SNP (2.5 mM) for 24 h. Apoptosis was assessed by Hoechst 33342 staining. (a) Control, (b) SNP only, (c) SNP + linalool, and (d) quantification of Hoechst staining, calculated from intensity values. Data are presented as means ± SEMs (error bars). ### p < 0.001 compared with the control group; * p < 0.05 compared with the SNPonly group. |
