Genetic changes outside nuclear DNA suspected to trigger more than half of all cancers
A buildup of chemical bonds on certain cancer-promoting genes, a process known as hypermethylation, is widely known to render cells cancerous by disrupting biological brakes on runaway growth. Now, Johns Hopkins scientists ...
