Detailed explanation-1: -Tumor suppressor genes represent the opposite side of cell growth control, normally acting to inhibit cell proliferation and tumor development. In many tumors, these genes are lost or inactivated, thereby removing negative regulators of cell proliferation and contributing to the abnormal proliferation of tumor cells.
Detailed explanation-2: -Tumor suppressor genes are normal genes that slow down cell division or tell cells to die at the right time (a process known as apoptosis or programmed cell death). When tumor suppressor genes don’t work properly, cells can grow out of control, which can lead to cancer.
Detailed explanation-3: -In contrast to the cellular proliferation-stimulating function of proto-oncogenes and oncogenes that drive the cell cycle forward, tumor suppressor genes code for proteins that normally operate to restrict cellular growth and division or even promote programmed cell death (apoptosis).
Detailed explanation-4: -Tumor Suppressor Proteins Control Cell Growth Tumor suppressor proteins regulate orderly cell growth and differentiation by sensing the surrounding environment, transmitting signals to the nucleus, and directly affecting transcription, translation, survival, or cell division.
