Zombie gene' protects elephants from cancer

The video discusses the lower cancer rates in elephants compared to humans, despite elephants having more potentially cancerous cells. This is attributed to elephants having over 20 copies of the tumor suppressor gene P53, which prevents DNA damage from leading to cancer. A study from the University of Chicago found that P53 can activate an inactive pseudogene in elephants called LIF6, which helps destroy damaged cells by targeting mitochondria.
