Polymorphisms of peroxiredoxin 1, 2 and 6 are not associated with esophageal cancer

Purpose  

Peroxiredoxins, which reduced intracellular peroxides as a noval kind of antioxidant protein, were extensively expressed in various types of cancers and were thought as a biomarker of cancer cells. In this work, we performed genotyping analyses for tag SNP of Prdx 1, 2 and 6, and then evaluated the association with susceptibility and clinic stage of esophageal squamous cell carcinoma (ESCC) in a case–control study.
