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 African elephant genes to determine if he possessed other genes for cancer control.
Crabs occur when a DNA gene is transformed, allowing cells to grow and reproduce in a harmful and uncontrollable way.
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 revive another destructive gene and assign them to kill cancer cells, as in other animals, including bats.
The vital gene, called LIF6, targets cells that are about to turn into cancerous tumors and destroy them.
Experiments have enabled researchers to find that when elephants begin to be exposed to carcinogenic lesions, the tumors progressively diminish by activating 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.
