Introduction The presence of Merkel cell polyomavirus (MCPyV) was identified in Merkel cell carcinoma (MCC). HHS Merkel cell carcinoma (MCC) is a neuroendocrine cancer caused by Merkel cell polyomavirus (MCV) that encodes a T antigen oncogene. We studied MCC samples by digital transcriptome subtraction and detected a fusion transcript between a previously undescribed virus T antigen and a human receptor tyrosine phosphatase.

Merkel cell carcinoma is a highly aggressive type of skin cancer that was first described by Cyril Toker in 1972 as "trabecular tumor of the skin". An intact retinoblastoma protein-binding site in Merkel cell polyomavirus large T antigen is required for promoting growth of Merkel cell carcinoma cells. The standard treatments for melanoma and Merkel cell skin cancer include surgery, targeted therapy, immunotherapy, and, less commonly, radiation therapy.

It is extremely rare in children and more common in whites and in men than in women. Merkel cell carcinoma (MCC) is a rare but aggressive human skin cancer that typically affects elderly and immunosuppressed individuals, a feature suggestive of an infectious origin. Notably, however, it was even more efficient than shRNA-mediated downregulation of LT expression. Merkel cell carcinoma (MCC) is also called neuroendocrine carcinoma of the skin.

Merkel cells are a type of neuroendocrine cell. Although new insights in the mechanisms of primary and secondary resistance pave the way for development of further immunotherapy strategies, neoadjuvant strategies may challenge our whole approach of the disease. Derm. Mechanistically, artesunate predominantly induces ferroptosis in MCPyV-positive MCC cells since known ferroptosis-inhibitors like DFO, BAF-A1, Fer-1 and β-mercaptoethanol reduced artesunate-induced death.

Cross-section of skin, normal Merkel cells are shown in red and connect to nerves shown in yellow. Polyomavirus-driven Merkel cell carcinoma: Prospects for therapeutic vaccine development. They are abundant in highly sensitive skin like that of the fingertips in humans, and make synaptic contacts with somatosensory afferent nerve fibers. J. Surg. Since artesunate-a drug used to treat malaria-has been reported to possess additional anti-tumor as well as anti-viral activity, we sought to evaluate pre-clinically the effect of artesunate on MCC. J. Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer, which is associated in 80% of cases with the Merkel cell polyomavirus (MCPyV). It’s not yet clear exactly how damage from UV light, infection with MCV, and changes in the body’s immune system might interact to cause MCC, but this is an active area of research. New immune checkpoint inhibitors have recently been demonstrated to be efficacious in advanced or refractory disease 4,5. 3 It typically presents as an asymptomatic pink, red, or bluish firm dome-shaped nodule. 2015;81:802–806. The cells are very close to nerve endings, and help the skin sense light touch. We used the indicated cell lines which were stably transduced with a vector allowing doxycyclin (Dox)-inducible expression of a T antigen (TA) shRNA as well as with a vector constitutively expressing an RB1 shRNA.

Merkel cell carcinoma (MCC) is considered an aggressive type of cancer, even more aggressive than melanoma. Dramatic Increase in the Incidence and Mortality from Merkel Cell Carcinoma in the United States. Merkel cell carcinoma (MCC) is an aggressive cutaneous malignancy with poor prognosis. Although it accounts for an estimated 1% of all cutaneous skin cancers, it is the second leading cause of death from skin cancer behind melanoma6. Merkel cell carcinoma occurs when these cells grow out of control. This means that it rapidly grows and spreads to nearby tissues or distant parts of the body (metastasizes). It is also known as cutaneous APUDoma, primary neuroendocrine carcinoma of the skin, primary small cell carcinoma of the skin, and trabecular carcinoma of the skin. They were originally described in the late 1800s by Friedrich Merkel, a German anatomist. (outer layer of the skin).
