U.S. scientists opened a previously unknown virus, which seems to cause the most dangerous form of skin cancer. The virus, called Merkel cell polyomavirus present in 80% of tumors of this type. Merkel cell carcinoma of an aggressive malignant tumor of the skin, especially the elderly and immunocompromised patients, especially AIDS patients and people who have undergone organ transplantation affects. Merkel cells are in the deep layers of the epidermis of the skin and are responsible for tactile sensitivity. The researchers examined tissue samples of Merkel cell tumors and found foreign DNA integrated into their own genome tumor. Study leader Patrick Moore and his colleagues found that the DNA previously unknown virus type polyomavirus belongs. This virus has been isolated from 80% of the added tissue samples of cancer, Merkel cells and 8% of control tissue samples from different parts of the body healthy. Scientists believe that the virus. A protein that promotes the growth of tumors, or the gene that affect to inhibit the growth of the tumor They suggest that the virus is one of the main factors that promote the growth of the tumor. According to Patrick Moore, the results can be the basis for the treatment of the disease and its prevention. Even the scientists said that the results are not conclusive and needs further confirmation.
