This conclusion was supported by another recent nested case-control study147 in which IgG antibody to JC virus was measured in 611 colorectal cancer cases, 123 adenomatous polyp cases, and matched controls. There was no association between antibodies to JCV and colorectal cancer, with OR 0.91 (...
Polymerase chain reaction (PCR) amplification of JC virus (JCV) T-antigen (T-Ag) DNA sequences in adenomatous polyps of the colon using specific primers that amplify a 154-bp NH2-terminal region of JCV T-Ag. Top: Results from 8 different polyps and a positive control. Bottom: Results fr...
The JC virus genome was identified by polymerase chain reaction in five of the seven immunohistochemically positive cases; transcriptional control region and viral protein 1 were amplified in, respectively, three and four cases. Transcriptional control region sequence analysis revealed major rearrangements ...
Recently, virus reactivation associated with immune modulatory drugs has also been an issue. Since 2005, natalizumab, a monoclonal antibody used for multiple sclerosis and Crohn's disease, has been repeatedly described to increase the incidence of PML. The disease may also occur in those who have...

Objective: This study aimed to assess the proportion of natalizumab-treated patients who converted to a positive anti-JCV antibody serostatus before and during the pandemic. Methods: Data from TYSABRI Outreach: Unified Commitment to Health (TOUCH) for 22,375 US patients treated with natalizumab ...
a plasmid containing the whole genome of the JCV Mad-1 strain. The standard curve was then used to extrapolate the viral load of each sample. Negative and positive controls were included in each reaction and each sample was tested in triplicate. All Q-PCR analyses were done by using Light ...
Sections of normal and diseased brain and kidney tissues were screened for the presence of JC virus (JCV) DNA by using the polymerase chain reaction. As expected, all samples obtained from patients with progressive multifocal leukoencephalopathy (PML) tested positive when multiple JCV-specific primer...
