The human polyomaviruses JC virus (JCV) and BK virus (BKV) are oncogenic in experimental systems and commonly infect humans. JCV DNA has been reported to be present in human colon mucosa and in colorectal cancers. To investigate whether the risk for colorectal cancer is associated with JCV or BKV infection, we performed a case-control study nested in the(More)
Measurement of antibody titres to the human polyomaviruses BK and JC has for many years had to rely on Hemagglutination inhibition. In recent years, viral serology based on virus-like particles (VLPs) in enzyme immunoassays (EIAs) has become widely used for a variety of viruses. We sought to establish a modern method for serological diagnosis of BK and JC(More)
Possible human infection with simian virus 40 (SV40) has been of great concern ever since SV40 was discovered in polio vaccines. Human populations are SV40-seropositive, but because of serological cross-reactivity between SV40 and the human polyomaviruses BK virus (BKV) and JC virus (JCV), it is debatable whether these antibodies are specific. An(More)
BACKGROUND Epigenetic variation has been linked to several human diseases. Proliferative diabetic retinopathy (PDR) is a major cause of vision loss in subjects with diabetes. However, studies examining the association between PDR and the genome-wide DNA methylation pattern are lacking. Our aim was to identify epigenetic modifications that associate with and(More)
Simian virus 40 (SV40), a polyoma virus of the rhesus macaque was discovered in 1960 as a contaminant of human polio vaccines produced in monkey cells. A number of studies have reported the detection of SV40 nucleotide sequences in human tumors, mainly mesotheliomas, but the reports have not been consistent. The presence of SV40 in 26 consecutive cases of(More)
