Which virus is implicated in Burkitts lymphoma?
## Core Concept
Burkin lymphoma is a type of B-cell non-Hodgkin lymphoma, and it is known to be associated with a specific viral infection. The underlying principle here involves the relationship between viral infections and the development of certain types of cancers. Specifically, this question tests knowledge of the viral etiology of Burkitt's lymphoma.
## Why the Correct Answer is Right
The correct answer, , is implicated in Burkitt's lymphoma because it carries the **c-MYC** gene, which is a proto-oncogene. When this gene is translocated to one of the immunoglobulin gene regions due to the viral infection, it leads to overexpression of the c-MYC protein. This overexpression drives the proliferation of B cells and contributes to the development of Burkitt's lymphoma. The Epstein-Barr virus (EBV) is detected in nearly all cases of endemic Burkitt's lymphoma and in about 20% of cases of sporadic Burkitt's lymphoma.
## Why Each Wrong Option is Incorrect
* **Option A:** - This option is incorrect because while some viruses are associated with cancer (e.g., HPV with cervical cancer), is not specifically linked to Burkitt's lymphoma.
* **Option B:** - This option is incorrect because, although can cause severe disease in humans, it is not associated with Burkitt's lymphoma.
* **Option D:** - This option is incorrect because is not commonly linked to Burkitt's lymphoma.
## Clinical Pearl / High-Yield Fact
A key point to remember is that Burkitt's lymphoma is highly associated with **Epstein-Barr virus (EBV)**, particularly in endemic cases. This association is so strong that EBV is considered a major risk factor for the development of Burkitt's lymphoma, especially in equatorial Africa where the disease is endemic.
**Correct Answer: C. **
