摘要:: Prostate cancer is the second leading cause of cancer deaths among men in the United States,but the precise molecular events leading to prostate carcinogenesis are not well understood. We isolated histologically defined cell populations from prostate cancer and its preinvasive lesions using laser capture microdissection, and performed genetic analysis on the mitochondrial genome, a sensitive cytoplasmic DNA. An extremely high incidence of somatic mutation (90% of prostatectomy cancer specimens) was found in the control region (the displacement loop) of mitochondrial DNA. The massive induction of lesion-associated mutations suggests active mitochondrial mutagenesis in both prostate cancer and its preinvasive lesions. Inspection of these mutations provides new insights into prostate cancer genetics and reveals unique patterns of somatic mutations in prostatic neoplastic lesions.
