Popis: The simian polyoma virus SV40 has been detected in specific human tumors including non-Hodgkin’s lymphomas, although a causative role for the virus has not been convincingly demonstrated. Aberrant methylation of CpG islands in promoter regions is a frequent method of silencing tumor suppressor genes (TSGs) in cancers and may be induced by oncogenic viruses. We investigated the relationship between the presence of SV40 or EBV DNA sequences and the methylation profiles for 10 TSGs in 90 cases of non-Hodgkin’s lymphomas/leukemias and 56 control tissues. SV40 sequences were present in 33/90 (37%) non-Hodgkin’s lymphomas/leukemias, and EBV was present in 11/42 (26%) of non-Hodgkin’s lymphomas. We found a highly significant correlation between the presence of SV40 and methylation of seven genes (P values, 0.006 to
