Discover small RNA can control host's gene in the rice
Can the rice adjust and control your gene too? Yesterday, issued the new discovery of professor's seminar of a time house of academy of sciences of the life of university student in Nanjing online in " cell research ": Some small RNA can be " alive " after cooking, chewing, digesting in the rice Enter animal's body, and control " host " directly Gene! You eat the next rice, some small RNA contained in the rice grain can " run " Enter your blood, " bad " that makes in your blood Cholesterol - -It is difficult for lipoprotein of low density to be removed. Zhang ChenYu says, finds this phenomenon, he himself is very surprised. And heredity " The book from heaven " DNA is different, RNA looks like a worker even more, can take the initiative and " translate " the content in DNA Come out, exercise various physiological functions. In the past, the scientist thought various RNA were that the life entity " marketted one's own products" ,The one that finds in RNA family but this time " The little chap " --Small RNA can unexpectedly " Step the circle " Work, produce in the plant, can " stir up trouble " behind being eaten the belly any more by the animal . Zhang ChenYu introduces, small RNA is very special, only 19-24 pieces of nucleotide makes up, but can exist in mammalian serum and blood plasma steadily, but that has not thought of is that small RNA of the plant can measure to while organizing the serum sum of many kinds of animals unexpectedly, "and mainly pass ' eat ', enter in animal's body. " This time, what the seminar pays close attention to is the plant small RNA that the serial number is 168a in rice. Its content in the rice is very abundant. Zhang ChenYu says, the experiment finds, it can bind with messenger ribonucleic acid of a gene in the liver, inhibit the albumen of this gene from expressing, and then slow down lipoprotein of low density from the speed that is removed in the blood plasma. "This will make the intersection of people and getting easy supersession diseases such as hyperlipemia, diabetes,etc.. " He say research show in the past, Chinese supersession syndrome such as diabetes more than westerner, perhaps this relates to our diet structure relying mainly on rice. As the saying goes, the water and soil raise the people of one party in one party. Some place is often " Eaten " Plant can through small for RNA,can't participate in animal and even human evolution course? News release of " Nature " is commented in this way: "This achievement has shown a kind of brand-new ubiquitous life regulation mechanism to us: How did animal and plant exchanged on the aspect of molecule across the circle. " The result arises through small RNA too in Chinese herbal medicine? " cell research " is carried out and edited the Li 's and grown and said, this discovery, in order to know Chinese herbal medicine scientifically, open up a new angle. Can small RNA in animal's internal organs enter the human body too? The Li 's grows and says, this is more possible. "Old old saying say, take what mend anything, but all await a large amount of follow-up test, prove. " (intern reporter Gong XiaoLei and Xu QiMin)
