Most cancers are caused by a large variety of factors that vary from one person to another. To unravel this complexity, genes that contribute to the development of a respective cancer must be identified. Such genes are called oncogenes. A good example of an oncogene is CDK8: Cyclin-dependent kinase 8.... NEWS MEDICAL · 4 weeks
