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. In combination with other genetic mutations, this … See more The discovery of oncogenes and their ability to deregulate cellular processes related to cell proliferation and development appeared first in the literature as opposed to the idea of tumor suppressor genes. … See more The proteins encoded by most tumor suppressor genes inhibit cell proliferation or survival. Inactivation of tumor suppressor genes therefore leads to tumor development by eliminating negative regulatory proteins. In most cases, tumor suppressor proteins … See more Gene therapy is used to reinstate the function of a mutated or deleted gene type.
