Epstein-Barr virus (EBV), is the herpesvirus that causes infectious mononucleosis and is associated with a number of cancers, particularly lymphomas in immunosuppressed persons including persons with AIDS EBV is a ubiquitous virus, so common that it has been difficult to determine whether it is the cause of certain diseases or whether it is simply there as an artifact

How p53 and Rb pathway function may be disrupted in cancer cells Components of the pathway which are found altered in human cancers are shown in red on the diagram above p53 and Rb themselves may be inactivated by gene mutation (loss of both copies or also as in familial retinoblastoma and Li-Fraumeni syndrome where there are inherited mutations in one copy of Rb or p53 gene respectively.
