Oncogenes Notes:

Oncogenes are those genes that have a primary role in causing cancer. Most normal cells undergo a programmed form of rapid cell death when critical functions are altered and do not function properly, however activated oncogenes can cause those cells, which were designated for apoptosis, to survive and proliferate instead. Most oncogenes begin as proto-oncogenes which are normal genes involved in cell cycle regulation, however if these genes are upregulated, they will predispose the cell to cancer.
