The Effect of Anti-oxidants on Apoptosis Relating Protein Expressions in Mutant Cu/Zn-superoxide Dismutase Motor Neuron Cells

ABSTRACT

BACKGROUNDS Free radical theory showed that aging might be correlating with the accumulation of oxidative damage into biomolecules of animals. Since the process was also observed in some neurodegenerative disease, the study on the subject could improve our understanding of the aging process. In this regard, our study laid focus on the effect of various anti-oxidants on the cells including mutant Cu/Zn-superoxide dismutase, which was reported to be deficient in various diseases or aging processes. METHODS: We tested retinol, Vitamin C, E and coenzyme Q10 on mutant Cu/Zn-superoxide dismutase(A4V) motor neuron cells using immunocytochemical study and accompanying statistical analysis. RESULTS: During our trial on the hydrogen peroxide treatment on A4V mutant cells, Vitamin A and C did not show any defensive effect on oxidative stress induced A4V cells while Vitamin E and coenzyme Q10 exhibited meaningful inhibitory effect against apoptosis relating protein expression. CONCLUSION: In case of oxidative damages induced by Cu/Zn-superoxide dismutase deficiencies, the protective role of some anti-oxidants like Vitamin E or coenzyme Q10 should be positively considered in forthcoming studies.
