oncogene
oncogene
Noun
pl: oncogenes
This term is used exclusively within medical, genetic, and biological contexts. It describes a specific type of gene that, while often starting as a proto-oncogene (a normal gene), becomes an oncogene through mutation or overexpression, leading to the development of a tumor.
In clinical discourse, the term carries a strong negative connotation associated with malignancy and cellular dysfunction. It is typically paired with verbs like trigger, activate, or express to describe the mechanism of carcinogenesis.
