Uncontrolled cell growth is often associated with mutations in genes encoding proteins that promote cell division. These regulatory proteins are known as mitogens or growth factors.
- The consequence of a mutation that leads to rapid and uncontrolled cell growth is that the organism would begin to develop cancerous masses.
- Cancer is uncontrolled cell growth, which is caused by mutations in genes involved in the control of cell division.
- A growth factor is a molecule capable of inducing cellular growth and proliferation.
- A mitogen is a protein that induces a cell to begin mitosis (e.g., the Platelet-derived growth factor).
