MODULE 5
An oncogene is defined as
a gene that causes or contributes to the development of cancer
What are the two types of evidence for oncogenic behavior?
In vivo
In vitro
What are the 4 criteria for In vivo oncogenic behavior
Cause cancer when activated in a transgenic animal
Render nontumorigenic cells tumorigenic
Knock down or knock out in tumorigenic cells renders the cells nontumorigenic
Activation/overexpression of the oncogene is strongly correlated with human cancer
What are the 3 criteria for In vitro oncogenic behavior
Causes anchorage-independent growth in soft agar (protection from anoikis)
Causes focus formation (loss of contact inhibition)
Renders cells growth factor independent

Five Ways to Activate Oncogenes
1. Mutation of genes to make it overactive.
