Zombie Gene Protects Elephants From Cancer

Over an organism’s life, cells keep on dividing and with each division the risk of acquiring a mutation that may lead to cancer increases. Therefore, it is normal to assume that larger animals with greater life spans have a high risk of developing cancer.

However, this is not the case for elephants who despite their 5500 kg body weight have a startlingly low rate of cancer. Such rarity has puzzled researchers for decades until a recent research study might have cracked the code. More specifically, researchers discovered a “zombie gene” that is protecting Elephants from acquiring cancer. This gene is called LIF6.
