Genetic variations in human benign prostatic hyperplasia detected by restriction landmark genomic scanning

Alterations in the genomic DNAs of benign prostatic hyperplasias were examined using restriction landmark genomic scanning. This methodology allows the visual comparison of a large number of loci as spots within a gel that has been electrophoresed in 2 dimensions. Within each of the 16 hyperplasias examined, we found 2 to 10 spots with altered intensities, as compared to equivalent spots from normal prostate, but could detect few common spot profiles for any hyperplasia samples. These data conflict with data from previous studies and suggest that there may be no consistent genetic changes in the pathogenesis of some forms of human benign prostatic hyperplasia.
