C‐terminal deletions of Merkel cell polyomavirus large T‐antigen, a highly specific surrogate marker for virally induced malignancy

Abstract excerpt

In 67-100% of cutaneous Merkel cell carcinomas (MCC) the Merkel cell polyomavirus (MCPyV) integrates into the host genome. Mutations and deletions truncating the C-terminal helicase domain of the T-antigen (TAg) protein have been detected in these MCCs, but not in healthy skin specimens. C-terminal deletions of the TAg nucleic acid sequences are characteristic for about 38% of these cases. While the association...
