Question

Quizplus · Accepted Answer

Mutations to proto-oncogenes, tumor suppressor genes, and growth factors can all contribute to the development of cancer. Proto-oncogenes normally regulate cell division, but mutations can cause them to become oncogenes, which promote uncontrolled cell division. Tumor suppressor genes normally limit cell division and inhibit the formation of tumors, but mutations can render them inactive, allowing abnormal cells to proliferate. Growth factors stimulate cell growth and division, but mutations can cause them to be produced in excess, promoting tumor growth. Therefore, mutations in any of these genes can contribute to the development of cancer.
