Elaidic acid induces apoptosis of SH-SY5Y cells. Cells were treated with Dulbecco's modified Eagle's medium or elaidic acid (20, 50 and 100 µM) for 24 h. Cell apoptosis was measured using AV-FITC/PI double staining and flow cytometry. (A) Representative dot plots. (B) Quantification of flow cytometry results. Data are presented as the mean ± standard error of three independent experiments. *P<0.05 vs. control group. AV, Annexin V; FITC, fluorescein isothiocyanate; PI, propidium iodide.
