68466-2Epstein-Barr virus-encoded RNA 1 [Presence] in Tissue by ProbeActive

Term Descriptions

This term is used for the detection of nuclear Epstein-Barr virus-encoded RNA 1 (EBER1) by in situ hybridization on tissue. Presence of EBER1 indicates a latent EBV infection.
EBV encodes two small nuclear RNAs, EBER1 and EBER2, which are the most abundant viral transcripts in latently infected cells. They are non-polyadenylated and thus not translated into protein. Their function is to inhibit interferon-mediated antiviral effects and apoptosis. Since they are expressed at high levels (around a million copies per latently infected cell), they are considered to be an ideal marker of latent EBV infection. In situ hybridization targeting one or both EBERs is used to determine whether a biopsied tumor is EBV-related.

The Epstein-Barr virus (EBV), also called Human herpesvirus 4 (HHV-4), is a virus of the herpes family (which includes Herpes simplex virus and Cytomegalovirus). It is one of the most common viruses in humans. Individuals infected with EBV are often asymptomatic but EBV commonly causes infectious mononucleosis. It is named after Michael Epstein and Yvonne Barr, who together with Bert Achong discovered the virus in 1964.
