WebDec 7, 2015 · Several oncogenes originally identified in retroviruses are now recognized as major drivers in human cancers, and drugs targeted at specific oncogene functions are used in cancer therapy . Furthermore, many proto-oncogenes are essential genes involved in fundamental processes in normal cells, like growth, metabolism, or differentiation. WebIf a proto-oncogene is mutated (changed) in a certain way, it becomes an oncogene. Cells that have these mutated oncogenes can become cancer. Normal cells also have genes called tumor suppressor genes, which help control how often normal cells divide in two, repair DNA mistakes, or cause cells to die at the right time. floa bank fonctionnement
