Accumulating evidence indicates that mitochondrial DNA alterations contribute to cancer development and progression. In this study, we evaluated the relationship between polymorphisms of mitochondrial NADH dehydrogenase subunit 3 (MTND3) and the risk of gastric cancer (GC). | Mitochondrial NADH dehydrogenase subunit 3 (MTND3) polymorphisms are associated with gastric cancer susceptibility
