Abstract:

In order to investigate the preventive effect of different ω-3/ω-6 constituent ratio of compatibility safflower seed oil (CSSO) on SH-SY5Y human neuroblastoma cells against oxidative cell damage, an oxidative cell damage model was established by using hydrogen peroxide (H2O2) as a donor of free reactive oxygen species, and after treatment of cells with different ω-3/ω-6 constituent ratios of CSSO, the alteration of cell viability and cellular apoptosis were determined by MTT (methyl thiazolyl tetrazolium) assay and flow cytometry. We successfully established the oxidative cell damage model of SH-SY5Y cells induced by H2O2, with the IC50 value of 1089.54 μmol/L H2O2. The preventive effect of CSSO against oxidative cell damage increased along with the decreasing amount of ω-3 content in CSSO. Moreover, at the ω-3/ω-6 ratio of 1:6.68 and effective dose range of 375~750 μg/ml CSSO, the cell viability was increased significantly to a higher level in the treatment group (84.1%) than in the control (61.1%), and cellular apoptosis was decreased markedly to a lower level (12.6%) in treatment group than in the control (25.9%). The results suggested that CSSO was able to protect the cells and prevent from oxidative cell damage caused by reactive oxygen species, and this effect may be closely associated with the ω-3/ω-6 constituent ratio in CSSO.
