...es. Many cancers – certain sarcomas, leukemias and lymphomas
– start with translocation. Existing methods result in the desired translocation of two chromosomes in one of every 1 million to 10 million cells cultured, Capecchi says, while the new method produces the desired result in one of every 100 cells....

Finnish scientists discovered a new approach to treat virus-induced lymphomas
...imary effusion lymphoma (PEL). PELs are aggressive lymphomas
with reported median survival time shorter than six months after diagnosis. Researchers at the University of Helsinki have discovered that activation of the p53 pathway offers a novel effective treatment modality for KSHV-infected lymphomas. The fin...

... and very long telomeres. These mice all developed lymphomas
by the time they were 7 months old. The researchers then continued breeding the mice to see what would happen in later generations. By the fifth generation, the researchers discovered that the mice had short telomeres and stopped developing lymphomas...
