Definition
Oncogenes are mutated forms of normal genes (proto-oncogenes) that promote cell division and survival, potentially leading to cancer when overactive. Tumor suppressor genes are normal genes that regulate cell growth and division, and their loss or inactivation can result in uncontrolled cell proliferation and tumor formation.
Summary
Oncogenes and tumor suppressor genes play crucial roles in the regulation of cell growth and division. Oncogenes, when mutated, can lead to uncontrolled cell proliferation, contributing to cancer development. In contrast, tumor suppressor genes act as safeguards, preventing excessive cell division and repairing DNA damage. A balance between these two types of genes is essential for maintaining healthy cellular function and preventing cancer. Understanding the mechanisms of oncogenes and tumor suppressor genes is vital for cancer research and treatment. Advances in genetic testing and targeted therapies are directly linked to our knowledge of these genes, allowing for more personalized and effective cancer treatments. As research continues, the potential for new therapies and prevention strategies based on this knowledge grows, offering hope for better cancer management.
