Most oncogenes regulate the proliferation of cells, but some inhibit differentiation (the process of cells becoming unique types of cells) or promote survival of cells (inhibit programmed death or apoptosis).

What is an oncogene What does it do what does this have to do with cancer?

A gene that is a mutated (changed) form of a gene involved in normal cell growth. Oncogenes may cause the growth of cancer cells. Mutations in genes that become oncogenes can be inherited or caused by being exposed to substances in the environment that cause cancer.

What is anti oncogene?

A tumor suppressor gene (TSG), or anti-oncogene, is a gene that regulates a cell during cell division and replication. If the cell grows uncontrollably, it will result in cancer. When a tumor suppressor gene is mutated, it results in a loss or reduction in its function.
