Abstract: Reactive oxygen is closely related to the occurrence and development of tumors.Manganese superoxide dismutase(MnSOD), as an antioxidant enzyme that scavenges superoxide anion in the mitochondrial matrix, plays an important role in maintaining mitochondrial redox homeostasis and protecting mitochondrial DNA.Many studies have discovered that MnSOD has different expression levels in different tumors, and has both anti-cancer and cancer-promoting functions, but its functional conversion mechanism remains unclear.This article intends to investigate the role of MnSOD in tumorigenesis and development, and to review the main regulatory mechanisms of its expression level and activity.

Key words: Manganese superoxide dismutase, Reactive oxygen species, Neoplasms
