High DJ-1 expression has been found in many types of tumors, including uveal melanoma, pancreatic ductal adenocarcinoma, non-small cell lung carcinoma, esophageal squamous cell carcinoma, breast cancer, hepatocellular carcinoma and ovarian carcinoma, and is significantly correlated with metastasis or poor survival outcomes (Davidson et al., 2008; He et al., 2012; Kim et al., 2005; Sitaram et al., 2009). This evidence concerns the gene PARK7 and breast carcinoma.
