Prevalence of JCV TAg DNA sequences and protein expression among the studied groups. A significant higher expression of JCV TAg was found in adenomas from LTRs than controls. Interestingly, JCV TAg DNA was significantly more amplifiable in normal mucosa samples obtained from LTRs than controls. No differences in JCV TAg DNA amplification were found in adenomas among the two groups, whereas no JCV TAg expression was present in any of the normal mucosa samples. *, P = 0.0002; #, P = 0.025.
