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.
n. a gene in a normal cell that is of identical structure to certain viral genes. Some are important regulators of cell division and damage may change them into *oncogenes.
A gene in a cancer cell that causes its growth to be uncontrolled. A regulatory gene that has changed and is responsible for uncontrolled growth.... oncogene
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
