Hello everyone, today says the Immortal Animal series: Naked Mole. Why say it, two reasons: 1. Naked mole rats have super anti-cancer ability, the whole rat does not have to worry about cancer 2. Naked mole rats are rodents, rodents average lifespan of 3-5 years, naked mole rats are 10 times theirs, almost 30 years. Let's say one by one:
First of all it looks like this:
Let's start with the anti-cancer ability of the first naked mole rat: In the 2013 journal Nature, it was reported that naked mole rats are rich in high molecular weight hyaluronic acid, which is more than five times that of humans or other rodents, which makes its cells very sensitive to each other, and once too tightly contacted, it will stop dividing, and its function can make naked mole rats have cancer resistance, and this mechanism may also be one of the reasons for the longevity of naked mole rats.
Here, hyaluronic acid is a polymer of polymers, which is a high-grade polysaccharide composed of unit D-glucuronic acid and N-acetyl glucosamine. D-glucuronic acid and N-acetylglucamine are connected by β-1,3-glycetic bonds, and disaccharide units are connected by β-1,4-glycetic bonds. In fact, it is hyaluronic acid, but I don't know if it is the same as the naked mole rat body, and there is a comment area that the big god knows to leave a high opinion.
The second is the ultra-longevity aspect of the naked mole rat: here it is said that the social structure of the naked mole rat is like bees and ants, the naked mole rat lives in the underground cave for a long time, and the environment of the underground cave is a lightless, low oxygen, high carbonic acid environment. The Israeli and Ukrainian research team conducted a controlled trial of naked mole rats (that is, the performance of the two groups of test subjects in different environments), one group in a normal environment, and one group simulating an underground low-oxygen, high-carbonic environment. Experiments have shown that naked mole rats have a slower metabolism and lower body temperature and appetite in a low-oxygen, high-carbonic environment. This is also an aspect of its longevity.
In 18 years, I first came into contact with the naked mole rat, it was an audio anchor said, he said one thing I remember deeply: that is, he said that the naked mole rat will not appear aging in its life, there is no distinction between juvenile, prime-age and old age, and the physical state has always been a young state. When I was chatting with my friend, I asked a question from my friend, and I immediately shut up. He said that naked mole rats do not distinguish between young adults and adults, how did they die? I was frozen in ice. Now think about the naked mole rat that the anchor said at that time will not have the phenomenon of aging in his life, and it is right to have no distinction between juvenile, prime-age and old age, but the physical state should now seem to be in a state of old age, because of the slow metabolism.
Well, that's it, or that sentence: I hope you will always be a teenager!
