Tumor suppressor genes can work in various ways to prevent the formation of tumors. Some of the key mechanisms include:
- Repairing DNA damage: These genes can facilitate the repair of damaged DNA, preventing mutations that could lead to cancer. - Inducing apoptosis: They can trigger programmed cell death (apoptosis) if a cell is damaged beyond repair. - Regulating the cell cycle: Tumor suppressor genes help control the cell cycle, ensuring that cells only divide when it is appropriate.
