This is why elephants do not die of cancer: A key clue in detecting drug for malignant diseases (VIDEO)
Although they have 100 times more cells than humans, elephants rarely get the disease. The death rate from this disease in these animals is 5 percent while in humans that percentage is much higher, 25 percentElephants, giant wild animals that live on average 50 to 70 years, are the only animals whose body successfully overcomes the malignant disease, naturally. In the study, which was published this week, scientists claim that genes of elephant can provide key mark in the fight against malignant diseases.
Although they have 100 times more cells than humans, elephants rarely get this disease. The death rate from this disease in these animals is 5 percent while in humans that percentage is much higher, 25 percent.
“Because of a large number of cells and their long-lived life, it would be more logical to be prone to this disease,” said one of the scientists.
Why is this so?
Specifically, as explained by scientists at the University of Utah, in the DNA of an elephant are found more discrepancies. These animals have additional genes that block the development of tumors.
“They have as many as 40 copies of the gene encoding the p53 protein, which is known for its properties that stops the development of malignant cells. The people on the other hand have only two copies of this gene,” said the researchers.
What does it mean for treating people?
Without the ability to naturally fight the cancer, the elephants would be already extinct by now. Because of the large number of cells, the chances of getting cancer are large.
“Nature had to take care to prevent malignant disease in these animals. We now need to do further detailed research so that we can apply to humans,” the scientists said.
