Scientists have been busy for years trying to understand why some animals do 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. Perhaps the most common answer is that larger animals have more cancer defenses, until scientists finally solve the mystery.
Elephants have a gene that works to revive another destructive gene and badign 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.
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.
