Oncogene - Wikipedia
An oncogene is a gene that has the potential to cause cancer. In tumor cells, they are often mutated or expressed at high levels.. Most normal cells will undergo a programmed form of rapid cell death when critical functions are altered and malfunctioning.Activated oncogenes can cause those cells designated for apoptosis to survive and proliferate instead.
Oncogene | biology | Britannica.com
Oncogene: Oncogene, genetic material that carries the ability to induce cancer. An oncogene is a sequence of deoxyribonucleic acid (DNA) that has been altered or mutated from its original form, the proto-oncogene. Operating as a positive growth regulator, the proto-oncogene is involved in promoting the
Oncogenes and tumor suppressor genes | American Cancer Society
Two of the main types of genes that play a role in cancer are oncogenes and tumor suppressor genes. Oncogenes. Proto-oncogenes are genes that normally help cells grow. When a proto-oncogene mutates (changes) or there are too many copies of it, it becomes a "bad" gene that can become permanently turned on or activated when it is not supposed to be.

Oncogene definition is - a gene having the potential to cause a normal cell to become cancerous.
Oncogene | definition of oncogene by Medical dictionary
oncogene [ong´ko-jēn] a gene found in the chromosomes of tumor cells whose activation is associated with the initial and continuing conversion of normal cells into cancer cells. on·co·gene (ong'kō-jēn), 1. Any of a family of genes that normally encodes proteins that are involved in cell growth or regulation (e.g., protein kinases, GTPases, nuclear ...
How Oncogenes Cause Cancer - NDSU
How Oncogenes Cause Cancer. The change of an oncogene from normal to cancerous function can be caused by a simple point mutation in the sequence of a gene. For example, a change in the ras oncogene, located on human chromosome 11, from guanine to cytosine is frequently associated with bladder cancer. This simple change results in glycine at ...

Mutations in genes that become oncogenes can be inherited or caused by being exposed to substances in the environment that cause cancer.

Oncogenes and cell survival. The oncogene proteins that signal cell survival include growth factors, growth factor receptors, PI 3-kinase, and Akt. Signaling by the PI 3-kinase/Akt pathway regulates members of the Bcl-2 family, which promote cell survival
Proto-Oncogenes and Tumor-Suppressor Genes - Molecular ...
An oncogene formed by the first mechanism encodes an oncoprotein that differs slightly from the normal protein encoded by the corresponding proto-oncogene.In contrast, the latter two mechanisms generate oncogenes whose protein products are identical with the normal proteins; their oncogenic effect is due to their being expressed at higher-than-normal levels or in cells where they normally are ...
