Why do elephants rarely get cancer? advertisement. Cancer is much less common in elephants than in humans, even though the big beasts' bodies have many more cells. Now researchers think they may have an explanation — one they say might someday lead to new ways to protect people from cancer.Elephants' cells contain 40 copies of a major cancer-suppressing gene called p53, two teams of scientists report. Humans have just two-one from each parent.The gene helps damaged cells repair themselves or self-destruct when exposed to cancer-causing substances.ow researchers think they may have an explanation — one they say might someday lead to new ways to protect people from cancer.

What causes a cell to become cancerous? Just an Answers enthusiast! Cancer happens when cells that are not normal grow and spread very fast. Normal body cells grow and divide and know to stop growing. Over time, they also die. Unlike these normal cells, cancer cells just continue to grow and divide out of control and don't die when they're supposed to.Another way of putting it is that normal cells sustain damage or alteration to their DNA and somehow promote themselves to become stem cells.nlike these normal cells, cancer cells just continue to grow and divide out of control and don't die when they're supposed to.

What elephants can teach scientists about fighting cancer in humans You've heard that elephants never forget, but did you know they almost never get cancer either? It turns out just 4.8% of known elephant deaths are related to cancer. For humans, cancer-related deaths are between 11% and 25%, scientists say. The low cancer rate among elephants is particularly intriguing because, all things being equal, elephants should get more cancer than we do. Elephants have about 100 times more cells than humans, and they live for about 70 years. That gives a lot of cells a lot of chances to mutate and become malignant over the course of a pachyderm’s lifetime.

Naked mole rats reveal why they are immune to cancer GIVE A GIFT. Naked mole rats reveal why they are immune to cancer. IF HUMANS lived as long relative to body size as naked mole rats, we would last for 600 years. These mouse-sized, subterranean African mammals live for over 30 years, and if that wasn’t impressive enough, they don’t get cancer. Now we have a clue why, which could lead to treatments for a variety of human conditions.

- When early-stage surgery removes the cancer while still contained, the prognosis is excellent and most rabbits live a full life. If the rabbit is not treated in the early stages, surgery is not effective because of metastasis. In these cases, the rabbit is severely compromised and the prognosis is very poor.

Stress DOES have an impact on cancer: Anxiety switches on a gene that speeds up the spread of the disease The 'stress gene' could one day function as a drug target to combat cancer spread. 'This suggests that the host stress response can help cancer to metastasize. 'If the body is in perfect balance, there isn't much of a problem. When the body gets stressed, that changes the immune system.

Some Cancer Mutations Slow Or Stop Tumor Growth Now Mirny and colleagues have discovered, to their surprise, that the passengers aren't there just for the ride. In sufficient numbers, they can slow down, and even stop, the cancer cells from growing and replicating as tumors.Cancer can take years to develop, sometimes decades.This is because it takes time for the cells to gradually acquire more and more driver mutations, which then switch on genes like Ras that spur tumor growth, and switch off genes like p53 that suppress tumor growth.ow Mirny and colleagues have discovered, to their surprise, that the passengers aren't there just for the ride.

Elephant Elephants use their teeth in sequence, not all at once. This means that, at any time, they only have one tooth in each jaw, a total of four. In total, they have 24 teeth: 12 front teeth, called premolars, and 12 back teeth, called molars. When the last molar wears out, the elephant dies because it cannot eat. They can live for about 70 years. But in a zoo or circus, people can keep elephants alive by feeding them soft food.

African Elephant African elephants are the largest land animals on Earth. They are slightly larger than their Asian cousins and can be identified by their larger ears that look somewhat like the continent of Africa.(Asian elephants have smaller, rounded ears.).Elephant ears radiate heat to help keep these large animals cool, but sometimes the African heat is too much. Elephants are fond of water and enjoy showering by sucking water into their trunks and spraying it all over themselves.Afterwards, they often spray their skin with a protective coating of dust.Asian elephants have smaller, rounded ears.).

- Upper incisor teeth develop into tusks in African elephants and grow throughout their lifetime. There are two subspecies of African elephants—the Savanna (or bush) elephant and the Forest elephant. Savanna elephants are larger than forest elephants, and their tusks curve outwards. In addition to being smaller, forest elephants are darker and their tusks are straighter and point downward.

Elephant endotheliotropic herpesvirus In African elephants, related forms of these viruses, which have been identified in wild populations, are generally benign, occasionally surfacing to cause small growths or lesions. However, some types of EEHV can cause a highly fatal disease in Asian elephants, which kills up to 80% of severely affected individuals.The disease can be treated with the rapid application of antiviral drugs, but this has only been effective in around a third of cases.he affected animals are mostly young Asian elephants that had been born in captivity,with half the cases in North America being between the ages of one and four years (and three-quarters between one and eight years old).

How Woolly Mammoths Survived Arctic Cold Mammoths, like their elephant cousins of today, would have been adapted to the warm climate they evolved in. In these climates, an elephant's biggest problem is getting rid of heat -- they do this with their big ears, through which many heat-porting blood vessels circulate. new study has found tiny genetic mutations that changed the way oxygen was delivered by its blood could be responsible for its tolerance to the cold climate. The woolly mammoth was an elephantid species and most closely related to today's Asian elephants.

- Asian elephants are smallest of all elephant species. They have a smaller body, smaller ears and females lack tusks. African savanna elephants are the largest of all the elephant species. They have large ears, a short and wide mandible, and both males and females have tusks.he skeleton of an elephant is shaped by its need to support the animal's massive weight. Elephants have stocky, sturdy limb bones and their feet are wide. The heel is reinforced with a cushion of dense connective tissue.
