Merkel cell polyomavirus and non-Merkel cell carcinomas: guilty or circumstantial evidence? They are located in the epidermis, however, invade into the dermis and deeper structures and blood vessels when becoming cancerous. Major issues remain unanswered regarding its oncogenesis and optimal treatment. (, T antigen knockdown is associated with decreased artesunate sensitivity of WaGa but not MKL-1 and MKL-2 cells. Merkel cell carcinoma is a disease of the elderly and usually affects individuals in their seventh and eighth decade of life with approximately 5% people aged <50 years being affected. Other polyomavirus species encode two minor capsid proteins, VP2 … Cross-section of skin, normal Merkel cells are shown in red and connect to nerves shown in yellow. Expression of the IDO1/TDO2-AhR pathway in tumor cells or the tumor microenvironment is associated with Merkel cell polyomavirus status and prognosis in Merkel cell carcinoma.

Merkel cell carcinoma tends to grow quickly and to metastasize (spread) at an early stage. Clipboard, Search History, and several other advanced features are temporarily unavailable. 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. Epub 2015 Oct 5. NCI CPTC Antibody Characterization Program. The crucial role the MCPyV small T oncoprotein was recently confirmed by its ability to inactivate p53, together with its contribution to the metastatic progression. The exact, underlying cause of the disease is not known, but there are several factors, including environmental and immunologic ones, that contribute to the development of the disease. Navitoclax combined with Alpelisib effectively inhibits Merkel cell carcinoma cell growth. Bone marrow involvement in MCC is rare and to our knowledge only nine cases reported in the English literature. Merkel Cell Polyomavirus and Merkel Cell Carcinoma.

Here we report on our institutional experience and outcomes treating patients with MCC. Merkel cell carcinoma (MCC) is a neuroendocrine cancer caused by Merkel cell polyomavirus (MCV) that encodes a T antigen oncogene. Surgery to remove the tumor is the primary treatment of all stages of melanoma. Indeed, in about 80% of cases, there is an association with Merkel cell polyomavirus (MCPyV); the expression of viral T antigens is crucial for growth of virus-positive tumor cells. Merkel cell carcinoma (MCC) is a rare form of skin cancer. 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. Merkel cell polyomavirus and non-Merkel cell carcinomas: guilty or circumstantial evidence? Major issues remain unanswered regarding its oncogenesis and optimal treatment.

Merkel cell carcinoma (MCC) is an aggressive and rare cutaneous cancer of the mechanoreceptor unit of the skin with a neuroendocrine origin. The cancer may derive from the microscopic Merkel cell nervous organ in the skin and viscera which is responsible for touch and pressure sensation. Clipboard, Search History, and several other advanced features are temporarily unavailable. Serine 220 phosphorylation of the Merkel cell polyomavirus large T antigen crucially supports growth of Merkel cell carcinoma cells. MCV encodes a major capsid protein, VP1, which forms the non-enveloped surface of the virion. (outer layer of the skin). Merkel cell carcinoma occurs when these cells grow out of control. Merkel cells are a type of neuroendocrine cell. In conclusion, our results revealed a highly anti-proliferative effect of the approved and generally well-tolerated anti-malaria compound artesunate on MCPyV-positive MCC cells, suggesting its potential usage for MCC therapy. Merkel cell carcinoma (MCC) is also called neuroendocrine carcinoma of the skin. Identifying the mechanisms of oncogenesis allow experimentation of new therapeutic targets, which remain mandatory even at the era of immunotherapies. 370 These tumors are uniformly positive for broad-spectrum cytokeratins and stain positively for CK20 in 97% of cases, with a dotlike pattern of reactivity (Fig. RB1 is the crucial target of the Merkel cell polyomavirus Large T antigen in Merkel cell carcinoma cells. The indicated MCPyV-positive MCC cell lines were cultured in the absence or presence of 50 µM artesunate (ART). Additionally, either 10 µM of the radical-trapping antioxidant ferrostatin-1 (Fer-1), 100 µM of the iron-chelator deferoxamine (DFO), 50 nM of the autophagy inhibitor bafilomycin-A1 (BAF-A1) (, Tumor growth is restricted in artesunate-treated mice. 2019 Feb;84:52-61. doi: 10.1016/j.humpath.2018.09.003. 2016 Jan 19;7(3):3403-15. doi: 10.18632/oncotarget.6494. Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer occurring in about 3 people per 1,000,000 members of the population. Indeed, in about 80% of cases, there is an association with Merkel cell polyomavirus (MCPyV); the expression of viral T antigens is crucial for growth of virus-positive tumor cells. Surg. Background Merkel cell carcinoma (MCC) is a rare, aggressive skin cancer associated with a high risk of metastasis. Derm. 2020 Dec 14;12:1758835920975621. doi: 10.1177/1758835920975621.

The standard treatments for melanoma and Merkel cell skin cancer include surgery, targeted therapy, immunotherapy, and, less commonly, radiation therapy. MCC; Merkel cell carcinoma; artesunate; ferroptosis; polyomavirus. This effect was accompanied by reduced large T antigen (LT) expression. Am. Finally, application of artesunate in xenotransplanted mice demonstrated that growth of established MCC tumors can be significantly suppressed in vivo. However, there was sparse information on the link of other common nonmelanoma skin cancers - basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) - … Treatment Clinical Trials for Merkel Cell Cancer Clinical trials are research studies that involve people. Acad. Would you like email updates of new search results? Merkel cells normally exist in the bottom (basal) layer of the epidermis, about 0.1 mm from skin's surface. It may spread quickly to surrounding tissues, nearby lymph nodes, or more distant parts of the body. receives speaker’s bureau honoraria from Amgen, Pfizer, Merck Serono and Sanofi, is a paid consultant/advisory board member for eTheRNA, Merck Serono, Pfizer, 4SC and Sanofi. It usually develops as a single, painless, bump on sun-exposed skin. (, Ferroptosis inhibitors rescue MCPyV-positive MCC cells from artesunate-induced cell death. This means that it rapidly grows and spreads to nearby tissues or distant parts of the body (metastasizes). 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. Author Summary Merkel cell polyomavirus (MCV or MCPyV) is a recently discovered member of the viral family Polyomaviridae. 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". Merkel cell carcinoma (MCC) is considered an aggressive type of cancer, even more aggressive than melanoma. Epub 2020 Mar 27. J.C.B. 2020 Oct 20;13:10651-10666. doi: 10.2147/OTT.S263976. Merkel cells are in the layer of basal cells at the deepest part of the epidermis and are connected to nerves. It is an aggressive type of cancer that can spread (metastasize) to other areas of the body. 10.51, Table 10.5). Normal cells can be transformed into cancer cells by viral oncogenes. Merkel cell carcinoma (MCC) is a rare, neuroendocrine, cutaneous malignancy that was first described in 1972 by Cyril Toker as “trabecular carcinoma of the skin” (REF. 1). 2012 Feb 15. Goh G, Walradt T, Markarov V, Blom A, Riaz N, Doumani R, Stafstrom K, Moshiri A, Yelistratova L, Levinsohn J, Chan TA, Nghiem P, Lifton RP, Choi J. Oncotarget. MCPyV-negative and MCPyV-positive MCCs have been hypothesized to derive from distinct cells, although the cell of origin remains a matter of debate. Recent findings: In advanced cases, tumoral microenvironment may adequately predict responses to immunotherapies, and several mechanisms of primary and secondary resistance have been investigated.
