PROTO ONCOGENES Meaning and
Definition
-
Proto-oncogenes are normal cellular genes that encode proteins involved in the regulation of cell division and growth. They are essential for maintaining balanced cellular proliferation and contribute to the development and growth of tissues and organs during normal physiological processes. Proto-oncogenes are characterized by their ability to potentially transform into oncogenes, which are genes with altered functions that can contribute to the development of cancer.
Proto-oncogenes play a crucial role in regulating cell growth by encoding proteins involved in signal transduction pathways that control cell division and differentiation. These proteins are typically receptor tyrosine kinases, growth factors, cytoplasmic kinases, and transcription factors. They work in harmony with other genes and proteins to ensure controlled cell growth and prevent uncontrolled proliferation.
Alterations in proto-oncogenes can lead to the conversion of normal cells into cancer cells. This can occur through various mechanisms, such as gene mutations, amplifications, or chromosomal translocations, which result in the activation of oncogenic functions. Once transformed, oncogenes can disrupt the delicate balance of cell proliferation and lead to uncontrolled growth, a hallmark of cancer.
Understanding the role of proto-oncogenes is crucial for deciphering the molecular basis of cancer development and progression. Targeting these genes and their downstream signaling pathways has become an important strategy for developing effective cancer therapies, as blocking the activity of oncogenic proteins can potentially halt or slow down cancer cell growth.

Etymology of PROTO ONCOGENES
The word "proto-oncogenes" has a Greek and Latin origin.
The word "proto" comes from the Greek word "protos", meaning "first" or "original". It is also used to indicate a precursor or an early stage of development.
The term "oncogenes" is derived from the Greek word "onkos", meaning "mass" or "tumor", and the Latin word "genes", meaning "born" or "origin".
In essence, "proto-oncogenes" refers to genes that have the potential to become oncogenes, which are genes involved in promoting cancerous growth. These proto-oncogenes are normal genes that, when mutated or overexpressed, can become oncogenic and lead to the development of cancer.
