Merkel cell carcinoma (MCC) is an aggressive neuroendocrine cancer of the skin with high rates of metastasis and mortality. Besides well-established factors including genetic mutations and UV-induced DNA damage in Merkel cell carcinogenesis, the recent discovery of the Merkel cell polyomavirus (MCPyV) has shed light on the viral etiology of MCC. In the current study, we provide novel evidence that MCPyV small T (sT) antigen induces the DNA damage response (DDR) pathway. Our data show that in human MCC cells, the presence of MCPyV is associated with hyperphosphorylation of histone H2AX, a marker for DNA damage. We observed that overexpression of MCPyV sT antigen induced the phosphorylation of histone H2AX as wel... More
