    ..In conclusion, demethylating agents effectively retard growth of TCC and RCC cell lines. Methylation level analysis of specific genes has the potential for further tumour characterisation in TCC and RCC. ..

    ..The different methylation pattern in testicular cancer might represent a different methylotype of this cancer. The extent of promoter methylation may be a promising target for application as a tumor marker in urogenital cancer disease. ..
