A tumor suppressor gene (TSG), or anti-oncogene, is a gene that regulates a cell during cell division and replication. [1] 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 order for a tumor cell to survive, it must decrease its expression of tumor suppressor genes such as p53, BRCA1, BRCA2, RB1, or the fas receptor. [4] [5] A tumor suppressor would trigger an apoptotic pathway in a cancer cell if there were DNA damage, polyploidy, or uncontrolled cell growth.
TP-53 is a gene that encodes for the protein p53; this protein is a tumor suppressor. p53 was discovered in 1979 stemming from a study involving cancer immunology and the role of viruses in some cancers. The protein was so named because it was measured to have a weight of 53 kDa.
Many of the genes involved in the Hippo signaling pathway are recognized as tumor suppressors, while Yki/YAP/TAZ is identified as an oncogene. YAP/TAZ can reprogram cancer cells into cancer stem cells. [26] YAP has been found to be elevated in some human cancers, including breast cancer, colorectal cancer, and liver cancer.
To tightly control cell division, cells have processes within them that prevent cell growth and division. These processes are orchestrated by proteins encoded by tumor suppressor genes. These genes take information from the cell to ensure that it is ready to divide, and will halt division if not (when the DNA is damaged, for example). In cancer ...
SDPR functions as a metastasis suppressor in breast cancer, potentially by priming cells to apoptosis. [8] Cancer cells suppress the gene via promoter DNA methylation hence exemplifies the significance of epigenetic changes in cancer progression. [9] [10] KISS1 is found in melanoma and breast cancers. It acts by synthesizing a protein receptor.
Under this model, cancer arises as the result of a single, isolated event, rather than the slow accumulation of multiple mutations. [4] The exact function of some tumor suppressor genes is not currently known (e.g. MEN1, WT1), [5] but based on these genes following the Knudson "two-hit" hypothesis, they are strongly presumed to be suppressor genes.
