such as Burkitt's lymphoma and Hodgkin's disease. Once a person is infected, these viruses can remain dormant for long periods within white blood cells before they burst out and begin replicating. This reactivation of the virus boosts the number of c...
$7.5 Million grant to Yale researchers for role of viruses in cancer
...Collaborating with DiMaio, she has found that some cancers
may be due to inaccurate DNA synthesis by error-prone DNA polymerases. "Working collaboratively on these related projects has enabled us to make much more rapid progress in understanding the molecular basis of cancer," said DiMaio. ...
