November 2014—Whole exome sequencing of Merkel cell carcinoma demonstrates conserved retinoblastoma pathway dysregulation: Merkel cell carcinoma is a rare aggressive neuroendocrine malignancy of the skin that is associated with infection by Merkel cell polyomavirus. Viral integration into the human genome and subsequent expression of the large T antigen is thought to cause cell cycle dysregulation via binding and inactivation of the retinoblastoma tumor suppressor protein and is a key step in the development of Merkel cell carcinoma.
