GENES found in mammalian cells and viruses that can cause cancer. They are believed to manufacture the proteins that control the division of cells. In certain circumstances this control malfunctions and a normal cell may be changed into one with MALIGNANT properties. Extensive research is being done with oncogenes with the aim of ?nding ways to prevent or control cancers.... oncogenes
A gene in a cell that regulates cell growth and development in an orderly fashion. If a protooncogene mutates, it can give rise to cancer by causing growth without the normal controls. The proto-oncogene is then called an oncogene.... proto-oncogene
