Merkel Cell Polyomavirus DNA in Persons without Merkel Cell Carcinoma
Merkel cell polyomavirus (MCPyV) DNA was detected in 88% of Merkel cell carcinomas in contrast to 16% of other skin tumors. MCPyV was also found in anogenital and oral samples (31%) and eyebrow hairs (50%) of HIV-positive men and in forehead swabs (62%) of healthy controls. MCPyV thus appears to be widespread.
متن کاملMerkel Cell Polyomavirus Positive Merkel Cell Carcinoma Requires Viral Small T Antigen For Cell Proliferation
These findings contradict existing evidence showing MCV sT protein expression in MCVMCC cancer tissues (Shuda et al., 2011) and cell lines (see Figure. 2, Houben et al., 2010) (Guastafierro et al., 2013). To investigate this discrepancy, we tried replicating Angermeyer et al's results using the same antibodies to detect MCV sT (CM8E6 (Kwunet al., 2009), CM5E1 (Shuda et al., 2011) and 2T2 ((Wang...
متن کاملMerkel cell polyomavirus-infected Merkel cell carcinoma cells require expression of viral T antigens.
Merkel cell carcinoma (MCC) is the most aggressive skin cancer. Recently, it was demonstrated that human Merkel cell polyomavirus (MCV) is clonally integrated in approximately 80% of MCC tumors. However, direct evidence for whether oncogenic viral proteins are needed for the maintenance of MCC cells is still missing. To address this question, we knocked down MCV T-antigen (TA) expression in MCV...
متن کاملMerkel Cell Polyomavirus Strains in Patients with Merkel Cell Carcinoma
We investigated whether Merkel cell carcinoma (MCC) patients in France carry Merkel cell polyomavirus (MCPyV) and then identified strain variations. All frozen MCC specimens and 45% of formalin-fixed and paraffin-embedded specimens, but none of the non-MCC neuroendocrine carcinomas specimens, had MCPyV. Strains from France and the United States were similar.
متن کاملMerkel Cell Polyomavirus: A Causal Factor in Merkel Cell Carcinoma
The RNA viruses hepatitis C virus and human T-cell lymphotropic virus type I (or human T-cell leukaemia virus type 1), and the DNA viruses hepatitis B virus, high-risk human papillomaviruses, human herpes virus-8 (Kaposi’s sarcoma-associated herpes virus) and Epstein Barr virus are acknowledged as carcinogenic to humans. Human polyomaviruses have oncogenic potentials in cell cultures and animal...
