Antioxidant induces DNA damage, cell death and mutagenicity in human lung and skin normal cells.

Abstract excerpt

Clinical trials have shown that antioxidant supplementation increased the risk of lung and skin cancers, but the underlying molecular mechanism is unknown. Here, we show that epigallocatechin gallate (EGCG) as an exemplary antioxidant induced significant death and DNA damage in human lung and skin normal cells through a reductive mechanism. Our results show direct evidence of reductive DNA damage in the cells. We...
