What is it about?

Cholesterol in foods can be oxidized to form a variety of oxysterols. Oxysterols substance have been demonstrated to exhibit toxic effects on cells. The ability of tocopherols (α-TOC and γ-TOC) to protect against oxysterol-induced cytotoxicity was also assessed.

Why is it important?

Pretreatment of cells with either α- or γ-tocopherol did not protect against oxysterol-induced cytotoxicity. The caco-2 cells treated with the high concentration (100 µm) of γ-tocopherol were found to be more susceptible to oxysterol-induced toxicity under the conditions employed in this study.

Perspectives

This research helped to further the research on the mechanisms of oxysterol toxicity and the use of antioxidants.
