Abstract:
The criteria that have led to the hypothesis according to which oncogenes play a role in the pathogenesis of cancer are briefly reviewed: "Certain genes normally present in cells in which they exert physiologic functions may become altered so as to induce cancer. Before acquiring carcinogenic properties, i.e. while they still exert their physiological function, these genes are referred to as proto-oncogenes; once they acquire their carcinogenic properties, they are called oncogenes". The importance modern techniques of molecular biology (genetic engineering and recombinant DNA) have had for the formulation of this hypothesis is stressed, as well as the involuntary contribution of retroviruses. The prospects are examined for therapeutic application that might derive from the oncogene hypothesis.
Insights
Proto-oncogenes are normal genes that can become cancer-causing oncogenes. This review covers the criteria supporting this hypothesis and its therapeutic implications.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Cancer pathogenesis involves genetic alterations.
- Proto-oncogenes are normal cellular genes.
- Proto-oncogenes can transform into oncogenes, inducing cancer.
Purpose of the Study:
- Review criteria supporting the oncogene hypothesis.
- Highlight the role of molecular biology techniques.
- Examine therapeutic prospects derived from the hypothesis.
Main Methods:
- Review of scientific literature.
- Analysis of molecular biology techniques (genetic engineering, recombinant DNA).

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
