Osmosis video - Oncogenes and tumor suppressor genes

Oncogenes and tumor suppressor genes are types of genes that play a role in the development of cancer. Oncogenes are mutated versions of proto-oncogenes, which normally regulate and promote the cell cycle to progress. Oncogenes end up promoting uncontrolled cell growth and division, causing normal cells to become cancerous. On the other hand, tumor suppressor genes are genes that code for protein products that regulate and slow down the cell cycle, and also promote apoptosis, which is programmed cell death.
