摘要: Introduction It has been suggested that oxidative stress and mitochondrial DNA damage play important roles in breast cancer carcinogenesis. Manganese superoxide dismutase (MnSOD) is a major enzyme responsible for the detoxification of reactive oxygen species mitochondria. A T → C substitution MnSOD gene results Val Ala change at -9 position targeting sequence (Val-9Ala), which alters protein secondary structure thus affects transport into
