Figure 4From: Mechanistic basis for protection of differentiated SH-SY5Y cells by oryzanol-rich fraction against hydrogen peroxide-induced neurotoxicity Annexin V-FITC and propidium iodide staining assay of SH-SY5Y cells following exposure to 250 μM H 2 O 2 over 24 h, in the presence or absence of 24 h Oryzanol-rich fraction (ORF) (100 μg/mL) pretreatment. Results are mean ± SD. # p < 0.05 versus control, *p <0.05 versus H2O2.Back to article page
