ONCOGENES Meaning and
Definition
-
Oncogenes are a type of gene that, when mutated or activated, have the potential to cause or contribute to the development of cancer. These genes are typically involved in regulating cell growth and division, ensuring that cells proliferate in a controlled manner. However, when alterations occur within these genes, their normal function can become deregulated, leading to unrestricted cell growth and the formation of tumors.
The mutations or activation of oncogenes can occur through various mechanisms, such as DNA mutations, gene amplification, or changes in gene regulation. Different types of oncogenes have been identified, each of which may play a role in specific cancers. Some examples of well-known oncogenes include HER2 (human epidermal growth factor receptor 2) in breast cancer, BCR-ABL1 in chronic myelogenous leukemia, and EGFR (epidermal growth factor receptor) in lung cancer.
Understanding oncogenes is crucial for the development of targeted cancer therapies. By identifying and characterizing oncogenes associated with specific cancers, researchers can develop drugs that selectively inhibit the activity of these genes or block the downstream pathways they activate. This approach aims to specifically target cancer cells, minimizing the impact on healthy cells and reducing side effects commonly associated with traditional treatments like chemotherapy and radiation therapy.
In conclusion, oncogenes are genes that, when mutated or activated, contribute to the development of cancer by promoting uncontrolled cell growth. Research in this field is essential for identifying potential therapeutic targets and developing more effective treatments for cancer.
Common Misspellings for ONCOGENES
Etymology of ONCOGENES
The word "oncogenes" has its roots in Greek and Latin. It comprises two components: "onco-" and "-genes", which combine to form "oncogenes".
The prefix "onco-" is derived from the Greek word "onkos", meaning "mass" or "bulk". In medical terminology, it is used to refer to tumors or cancer. The suffix "-genes" is derived from the Greek "genos", which means "birth", "origin", or "production". In the context of genetics, it refers to something that generates or produces a specific trait.
Combining the two components, "oncogenes" refers to genes that have the ability to initiate the development of cancerous tumors. These genes are often altered forms of normal genes involved in critical cellular processes, such as cell division, growth, and differentiation.
