Abstract:
Aim: To assess whether Omeg@Silica microparticles - fish oil from anchovy fillet leftovers (AnchoisOil) encapsulated within mesoporous silica particles - are effective in promoting antitumor effects in lung cancer cells. Methods: Three human non-small-cell lung cancer cell lines (A549, Colo 699 and SK-MES-1) were used. Cells were treated with AnchoisOil dispersed in ethanol (10 and 15 μg/ml) or encapsulated in silica and further formulated in aqueous ethanol. Cell cycle, reactive oxygen species, mitochondrial stress and long-term proliferation were assessed. Results & conclusion: Omeg@Silica microparticles were more effective than fish oil in increasing reactive oxygen species and mitochondrial damage, and in altering the cell cycle and reducing cell proliferation, in lung cancer cells. These in vitro antitumor effects of Omeg@Silica support its investigation in lung cancer therapy.
