Many growth factors are classified as which of the following?

Question

Quizplus · Accepted Answer

Many growth factors are classified as proto-oncogenes, which are normal genes that can become oncogenes when mutated. Proto-oncogenes play a role in promoting cell growth, and mutations in these genes can lead to uncontrolled cell growth and cancer. This is in contrast to tumor suppressor genes, which normally function to limit cell growth and prevent the development of cancer. Signal transduction pathway proteins are a broad category of proteins involved in transmitting signals within cells, including those involved in growth factor signaling. However, not all growth factors are signal transduction pathway proteins. Mutant tumor suppressors are tumor suppressor genes that have undergone mutations, leading to the loss of their tumor-suppressing function.
