Center for Elephant Conservation may have found the answer. According to the results, elephants have 38 additional modified copies of a gene (基因 ) that encodes p53, a welldefined tumor (腫瘤 ) suppressor, as pared to humans, who have only two. Further, elephants may have a more powerful mechanism for killing damaged cells that are at risk for being cancerous. In isolated elephant cells, this activity is doubled pared to healthy human cells, and five times that of cells from patients with LiFraumeni Syndrome, who have only one working copy of p53 and more than a 90 percent lifetime cancer risk in children and adults. The results suggest extra p53 could explain elephants? increased resistance to cancer. “Nature has already figured out how to prevent cancer. It?s up to us to learn how different animals overe the problem so we can adapt those strategies to prevent cancer in people,” says cosenior author Joshua Schiffman, ., pediatric oncologist (腫瘤學(xué)家 ) at Huntsman Cancer Institute, University of Utah School of Medicine, and Primary Children?s Hospital. According to Schiffman, elephants have long been considered a walking problem. Because they have 100 times as many cells as people, they should be 100 times more likely to have a cell slip into a cancerous state and cause the disease over their long life span of 50 to 70 years. And yet it?s believed that elephants get cancer less often, a theory confirmed in this study. Analysis of a large database of elephant deaths estimates a cancer death rate of less than 5 percent pared to 11 to 25 percent in people. 32.
