Protoonkogeeneista
Proto-oncogenes are normal genes that play a crucial role in cell growth, division, and differentiation. In their natural state, they are essential for the proper development and functioning of multicellular organisms. These genes are involved in various cellular processes, including signal transduction pathways that regulate cell proliferation and survival. Think of them as the gas pedal for cell growth, ensuring that cells divide when needed.
However, mutations can occur in proto-oncogenes, transforming them into oncogenes. These oncogenes are altered versions of
The conversion of a proto-oncogene to an oncogene is often a critical step in the development of
