Oncogenes. The growth control genes.

Genes that are involved in the development of cancer have been identified. These genes, called "oncogenes," are related to normal cellular genes called "proto-oncogenes," which code for proteins involved in the regulation of cellular growth and differentiation. Through the study of these genes, we now begin to assess prognosis of several malignant neoplasms. Moreover, specific inhibitors of oncogene activity have potential use in treatment regimens for cancer.
