A normal gene which, when altered by mutation, becomes an oncogene that can contribute to cancer. Proto-oncogenes may have many different functions in the cell. Some proto-oncogenes provide signals that lead to cell division. Other proto-oncogenes regulate programmed cell death (apoptosis). The defective versions of proto-oncogenes, known as oncoge [..]

A gene involved in normal cell growth. Mutations (changes) in a proto-oncogene may cause it to become an oncogene, which can cause the growth of cancer cells.

(pro-toh-onk-oh-jeen) A normal cellular gene corresponding to an oncogene; a gene with a potential to cause cancer, but that requires some alteration to become an oncogene.

Normal cellular gene that controls cell division. When mutated, it may become an oncogene and contribute to cancer progression. © 2005 by W. H. Freeman and Company. All rights reserved. Pierce [..]

A gene present in a normal cell which carries out a normal cellular function, but which can become an oncogene under certain circumstances. The prefix "c-" indicates a cellular gene, [..]

A gene present in a normal cell which carries out a normal cellular function, but which can become an oncogene under certain circumstances. The prefix "c-" indicates a cellular gene, and is generally used for proto-oncogenes (examples: c-myb

A cellular gene that can undergo modification to a cancer-causing gene (oncogene).

  A eukaryotic gene that functions to promote cellular proliferation or inhibit apoptosis, in which gain-of-function mutations (oncogenes) are associated with cancer.

A normal gene that has the potential to become an oncogene.

(n) a normal gene that has the potential to become an oncogene

A normal cellular gene that encodes a protein usually involved in regulation of cell growth or proliferation and that can be mutated into a cancer-promoting oncogene, either by changing the protein-co [..]

A gene involved in normal cell growth. Mutations (changes) in a proto-oncogene may cause it to become an oncogene, which can cause the growth of cancer cells.

Normal cellular gene, usually involved in growth control, from which an oncogene is derived as the result of a somatic mutation or viral recombination.

AKA: Cellular oncogene The non-activated form of a cellular oncogene in an untransformed cell. A gene that, when mutated or otherwise affected, becomes an oncogene.

Oncogenes are altered forms of normal cellular genes called proto-oncogene. Many proto-oncogenes are homologous to viral oncogenes and involved in the control of cell proliferation or differentiation. Mutations, amplifications or rearrangements of proto-oncogenes lead to upregulated or deregulated cell growth and allow them to function as oncogenes [..]
