Oncogene - Wikipedia, the free encyclopedia
An oncogene is a gene that, when mutated or expressed at high levels, helps turn a normal cell into a tumor cell. Many cells normally undergo a programmed form of death (apoptosis). Activated oncoge...

Carcinogenesis - Wikipedia, the free encyclopedia
Carcinogenesis ( the creation of cancer), is the process by which normal cells are transformed into cancer cells. Cell division is a physiological process that occurs in almost all tissues and unde...

What drives cancer cells to grow and divide uncontrollably and escape cell death? ... Proto-oncogenes are a group of genes that cause normal cells to become cancerous when they are mutated (Adamson, 1987; Weinstein & Joe, 2006). Mutations in proto-oncogenes are ...

When this happens, the proto-oncogenes become oncogenes, and this transition upsets the normal balance of cell cycle regulation in the cell, crafting uncontrolled growth possible.

Figure 1. Proto-oncogenes can become oncogenes. Proto-oncogenes encode for normal cellular proteins involved in growth signalling pathways. When these genes become mutated as a result of exposure to chemicals, radiation, or other carcinogens, these genes are called oncogenes.

Genes that participate in any one of the steps above can become oncogenes if: ... It is estimated that fully 1% of the 25,000 or so genes in the human genome are proto-oncogenes.

Gain-of-Function Mutations Convert Proto-Oncogenes into Oncogenes ... Although these cells survive infection, they become permanently transformed because the viral DNA contains one or more oncogenes. For example, many warts and other benign tumors of epithelial cells are caused by the DNA-containing papillomaviruses.
