Aliases:This biomarker is also known as:
- Parkinson disease (autosomal recessive, early onset) 7,
- Parkinson disease protein 7,
- Protein DJ-1,
- Oncogene DJ-1,
DJ-1, also known as PARK-7, belongs to the peptidase C56 family of proteins. It acts as a positive regulator of androgen receptor-dependent transcription. It may also function as a redox-sensitive chaperone, as a sensor for oxidative stress, and it apparently protects neurons against oxidative stress and cell death. DJ-1 is highly expressed in pancreas, kidney, skeletal muscle, liver, testis and heart and is detected at slightly lower levels in placenta and brain.

|QA State:||Under Review|
Validation study was conducted to determine whether DJ-1 antigens are associated with autoantibodies in sera collected at the pre-symptomatic stage of lung cancer.

Validation of Protein Markers for Lung Cancer Using CARET Sera and Proteomics Techniques
1.1 To validate the finding from pilot studies with CARET sera of autoantibodies to annexins I and II and PGP9.5 as potential biomarkers for lung cancers before the clinical diagnosis, evaluating sensitivity and specificity by time before diagnosis, treatment arm, gender, histologic type, and smoking status. 1.2 To determine whether a pattern of occurrence of autoantibodies in lung cancer sera may be diagnostic of lung cancer that is not dependent on the occurrence of any particular autoantibody. 1.3 To compare the findings for individual biomarker candidates and combinations of biomarker candidates in participants who were current smokers versus former smokers.View more about this study
