WebTumour suppressor genes, like proto-oncogenes, are involved in the normal regulation of cell growth; but unlike proto-oncogenes, which promote cell division and differentiation, tumour suppressors restrain them. If proto-oncogenes are the accelerators of cell growth, tumour suppressor genes are the brakes. WebTumor suppressor genes. These are protective genes. Normally, they limit cell growth by: Monitoring how quickly cells divide into new cells. Repairing mismatched DNA. Controlling when a cell dies. When a tumor suppressor …

WebTumor suppressor genes are segments of DNA that code for negative regulator proteins, which keep the cell from undergoing uncontrolled division. Mutated p53 genes are believed to be responsible for causing tumor growth because they turn off the regulatory mechanisms that keep cells from dividing out of control. WebA 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.
