Scientists have been busy for years trying to understand why some animals did not have cancer, such as elephants and whales.
With multiple hypotheses that very large animals protect them from the causes of cancer, an American scientist has discovered in elephants a unique gene that protects them from malignant diseases.
In 2012, a scientist named Vincent Lynch decided to examine the genes of the African elephant to determine if he possessed other carcinogenic genes.
Scientists believe that large animals are made up of more cells. Cancer genes therefore need more time to be fatal to larger animals.
Since then, scientists have formulated dozens of hypotheses to understand why elephants do not attack cancer. The most common answer may be that larger animals have more cancer defenses until scientists finally solve the mystery, which is no longer dependent on size.
Elephants have a gene that works to reactivate another destructive gene and badign it to kill cancer cells, identical to those found in other animals, including bats.
In experiments, the researchers found that when elephant cells begin to be exposed to carcinogenic lesions, tumors progressively diminish by triggering the lifesaving defense system, the LIF6 gene.
Scientists hope to find drugs that mimic the effect of the cancer resistance gene and develop revolutionary new treatments for future cancer patients.
