To discover the new glycoprotein from the jellyfish, in adaptation to the medical supply and the cosmetics expectation

The Institute of Physical and Chemical Research and trust harmony chemical engineering being joint, new discovered the fact that the glycoprotein which is called “the mucin” is included in large quantities in the jellyfish, announced the structure that it succeeded in specifying.
　As for the new mucin which this time is discovered, the mucin and the structure which are included as the main component of the gastric fluid of the person have been similar, you can expect use to the medical supply and the cosmetics and the food additive and the like. You say that it has the function of anti-bacterial action and the preservation moisture effect etc which, protect the body from the bacterium and the virus. The same substance exists, it inhabits in the Japanese coast such as [echizenkurage] and [mizukurage] being in common to many jellyfish kinds.
　The method so far industrially of producing the mucin in large quantities was limited to the gastric mucin and the like of domestic animal origin. As for the new mucin, in addition to the fact that mass production is possible, you say that there is a possibility where it can utilize with the conversion and the like of the sugar chain, as the high-level medical supply material.
　Problem such that hypofunction of the atomic energy thermal power generation plant and the like where the jellyfish, when it occurs in large quantities, gives damage to fishing industry, utilizes the seawater is brought occurs. Collecting, to utilize in the food and the like, it was necessary for it not to be possible, it abolishes to deal with. With the latest result, these problems are solved, effective utilization to the high added value product whose safety is high is expected.

News Inside News :

The independent administrative corporate body Institute of Physical and Chemical Research (field depending well chief director Osamu) with the trust harmony chemical engineering corporation (Representative President Wada Hiroshi man) being joint, it is seen normally in the Japanese coast , being in common to many jellyfish kinds, “the mucin (one kind of glycoprotein)” you discovered the fact that it is included in large quantities, you succeeded in deciding the structure. This the Riken Research Center (saw grass happiness two chief) is the result of the ox rice field public correcting/rule research unit leader and others of environmental software material research unit. Furthermore, three Tsu fishing industry production union of Kyoto prefecture capital Tango city (Hiroshi line union length) there was self-sacrifice cooperation of the union member in this discovery.
The chemical compound which you discover, structure relatively being simple, is included as main component such as gastric fluid of the human “MUC5AC * it has the structure which 2” you call resembles closely with the mucin. The mucin is included in the mucus of the various animals not only the human, we have shown anti-bacterial action and the preservation moisture effect which protect the body from the bacterium and the virus, because of the medical supply and health maintenance it is observed. In the gastric fluid of the human, catching the [prior] germ where the mucin which is included becomes cause of emergence of the stomach cancer, also it has become clear to do the function which controls activity. So far, as for the method industrially of producing the musing in large quantities, the gastric mucin etc of the domestic animal origin which is used the cosmetics and as the additive of the food it was limited. Because as for the new mucin, in addition to the fact that mass production is possible unlike these, chemical structure has become clear, it has the possibility of developing with the conversion and the like of the sugar chain, as a high-level medical supply material.
Discovery of the new mucin, as it accelerates such high added value product development, becomes something which offers the resource of the new mucin to human society. The mucin which is picked from the jellyfish, being simple, from the fact that it can produce in large quantities, also industrialization being easy, is thought that it can offer the mucin raw material whose price is cheap. As for this mucin production process, processing job of the jellyfish parallel, because it is possible, to advance, it becomes possible to solve the collection processing problem of the jellyfish which is handled as the waste with a stone two bird.
　With research unit, being associated with old thing description, “] (Neomycin)” with designation * 3 it did this chemical compound, it aimed toward the fact that it utilizes as the Riken original chemical compound it made the research start which already is directed to mass production. It is the schedule which pursues the possibility where it can create the industry where the public characteristic which devises the cost which preserves environment by in the future, expanding the range of utilization, acquire big added value is high.
　This research is adopted 2006 original seed development business of independent administrative corporate body technology promotion mechanism, as “industrialization of the new mucin production which is extracted from the jellyfish waste” even in theme of university departure venture creation promotion. This result is due to the cooperation publication of Americanization academic society and the American pharmacy meeting, 'the June 1st online it is published to Journal of Natural Products'. In addition, June the 6th industry-university-government cooperation propulsion meeting which on 16 and 17th is held at the Kyoto International Conference Center (Cabinet prefecture sponsorship) it is announced orally as “the new useful glycoprotein which is extracted from the jellyfishes (the mucin) a production” even in the technology explanatory meeting by the young researcher.
