Summary
Epstein-Barr virus (EBV) can cause cancer but usually persists harmlessly in memory B cells. EBV minimizes its oncogenic potential by residing in resting cells, though its role in tumor development varies by cancer type.
Area of Science:
- Virology
- Immunology
- Oncology
Background:
- Epstein-Barr virus (EBV) is linked to human cancers like lymphomas and carcinomas.
- Despite potent transforming activity in vitro, EBV persists benignly in over 90% of the population.
- The benign persistence suggests a mechanism for controlling EBV's oncogenic potential.
Purpose of the Study:
- To investigate how Epstein-Barr virus (EBV) persists lifelong in the human population.
- To understand the relationship between EBV latency and the development of EBV-associated tumors.
- To clarify the causative role of EBV in different human malignancies.
Main Methods:
- Analysis of EBV persistence in different B cell populations.
- Investigation of EBV's life cycle stages in latently infected B cells.
- Comparative studies of EBV contribution to various tumor types.
Main Results:
- EBV primarily persists in resting memory B cells, not proliferating cells.
- EBV utilizes growth-promoting abilities for memory access but downregulates oncogenic potential.
- EBV-associated tumors originate from distinct B cell life cycle stages.
Conclusions:
- EBV has evolved to balance persistence and oncogenesis by residing in resting memory B cells.
- The specific stage of B cell latency influences EBV's role in tumor development.
- EBV's causative role in cancer is definitive in some cases (e.g., immunoblastic lymphoma) but less clear in others (e.g., Burkitt's lymphoma).

01:03Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

01:51Mechanisms of Retrovirus-induced Cancers
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

02:33Retroviruses
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
01:27Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
