Epstein-Barr virus is an etiologic factor in multiple types of cancer that
primarily develop in lymphocytes and epithelial cells. The tumors are latently
infected yet express distinct subsets of viral proteins that are essential for
transformation. The viral oncogenes may be expressed in a subset of cells and are
transferred through exosomes to many cells to induce growth and alter the tumor
environment. In some of the viral cancers, viral proteins are not expressed,
however, the viral miRNAs can alter growth by decreasing expression of negative
regulators of cell growth such as tumor suppressors and cellular proteins that
induce apoptosis.
