Because cancer cells acquire mutations in oncogenes — genes that can transform cells into cancer cells — to support their growth and survival, a great deal of research has focused on identifying oncogenes that could be targeted by cancer drugs. (sciencedaily.com)
Scientists have long thought that cancer is an evolutionary process that involves cells acquiring mutations that replicate and persist over time, gaining an advantage over normal cells. (sciencedaily.com)
Influenza viruses evolve by acquiring mutations in the viral genome or by a process called reassortment. (sciencedaily.com)
