Abstract:
:DNA damage has been associated with prostate cancer risk. Men who were referred for initial prostate biopsy for elevated prostate-specific antigen or abnormal digital rectal examination are often found with no cancer but have a higher risk of developing prostate cancer than the general population of men in their lifetime. In this study, we investigated whether DNA damage is one of the factors that predispose these men referred for prostate biopsies to a higher risk of prostate cancer. We found significantly elevated levels of 8-oxo-2-deoxyguanosine immunoreactivity in the prostates of the referred men (n = 50) in comparison to the control prostates of men (n = 32) with no indication for referral for prostate biopsy. Twelve of these control men were healthy middle-aged men and 20 of them were older men whose conditions were diagnosed with bladder cancer but with normal serum prostate-specific antigen and digital rectal examination and no evidence of prostate disease. In all the 8-oxo-2-deoxyguanosine-positive prostates, we detected phosphorylation of the ataxia telangiectasia mutated kinase and expression of the immune-stimulatory molecule MIC in the prostate epithelium. These data suggest that: 1) oxidative DNA damage has occurred in the "referred" but pathologically normal prostates, indicating that these prostates may be subjected to genomic instability and eventually neoplastic transformation; 2) in response to DNA damage, two surveillance pathways, represented by ataxia telangiectasia mutated phosphorylation and induction of the NKG2D ligand MIC, were activated to prevent tumorigenesis.
