Oncogene PPT: Definition, History, Functions and Classification Free Download: An oncogene is a gene that has the capability to cause cancer. In tumor cells, those genes are regularly mutated, or expressed at excessive levels. Most regular cells will go through a programmed form of fast cell death (apoptosis) while crucial features are altered and malfunctioning.

Oncogene PPT: Definition, History, Functions and Classification

Activated oncogenes can cause the ones cells particular for apoptosis to survive and proliferate instead. Most oncogenes started out as proto-oncogenes: regular genes worried in cell boom and proliferation or inhibition of apoptosis. If, via mutation, regular genes promoting cellular growth are up-regulated (gain-of-characteristic mutation), they’ll predispose the cell to cancer; thus, they’re termed “oncogenes”.
