Tartigradesin supervoimat ovat ajankohtainen aihe kaikkialla maailmassa. Kuitenkin juuri kun luulit, ettei luonto voisi en\u00e4\u00e4 tulla hullummaksi, se yll\u00e4tt\u00e4\u00e4 sinut j\u00e4lleen.<\/p>\n

Tartigradit tunnetaan jo nyt maapallon vastustuskykyisimpin\u00e4 el\u00e4imin\u00e4.

Ei ole yll\u00e4tys, ett\u00e4 t\u00e4m\u00e4 pieni el\u00e4in her\u00e4tti joukon uusia kysymyksi\u00e4 siit\u00e4, miten evoluutio on voinut tapahtua.<\/p>\n

\"Tartigradesin<\/a><\/p>\n

T\u00e4ll\u00e4 viikolla, Nature-lehdess\u00e4 julkaistu uusi tutkimus<\/a>, paljasti paljon enemm\u00e4n tartigradesin supervoimista.<\/p>\n

Kun Takekazu Kunieda ja h\u00e4nen tutkijaryhm\u00e4ns\u00e4 olivat sekvensoineet tartigrades-el\u00e4inten perim\u00e4n, he l\u00f6ysiv\u00e4t proteiinin, joka suojaa DNA:ta, kun se altistuu s\u00e4teilylle. T\u00e4t\u00e4 proteiinia esiintyy vain tartigradeissa. Kunieda tutkii kuitenkin parhaillaan, miten sama proteiini voidaan tuoda ihmisiin ja suojata ihmisen DNA:ta.<\/p>\n

\u00a0\"On h\u00e4mm\u00e4stytt\u00e4v\u00e4\u00e4 n\u00e4hd\u00e4, ett\u00e4 yksi ainoa geeni riitt\u00e4\u00e4 parantamaan ihmissoluviljelm\u00e4n s\u00e4teilyn sietokyky\u00e4. Uskomme, ett\u00e4 t\u00e4m\u00e4 proteiini voi toimia fyysisen\u00e4 kilpen\u00e4, joka suojaa ihmisen DNA:ta hy\u00f6kk\u00e4yksilt\u00e4.\"<\/p><\/blockquote>\n

Tartigradesin supervoimien salaisuus on sen kyky kest\u00e4\u00e4 \u00e4\u00e4rimm\u00e4ist\u00e4 kuivumista. Tartigrades pystyy selviytym\u00e4\u00e4n vain 1% vedest\u00e4 ja palaamaan sitten takaisin el\u00e4m\u00e4\u00e4n kuin mit\u00e4\u00e4n ei olisi tapahtunut. Kuniedan mukaan tartigradit jakavat DNA:nsa pieniin palasiin ja pudottavat elintoimintonsa 0,01%:iin. Kun ne ovat j\u00e4lleen piiloutuneet, DNA korjaa itsens\u00e4 ja niiden el\u00e4m\u00e4naktiivisuus nousee takaisin 100%:iin.<\/p>\n

Genomin sekvensointi viittaa my\u00f6s siihen, ett\u00e4 suurin osa tartigradesin geeneist\u00e4 on per\u00e4isin muista el\u00e4imist\u00e4 \"horisontaaliseksi geenisiirroksi\" kutsutun prosessin kautta. T\u00e4ss\u00e4 on infografiikka, jossa on yhteenveto Kuniedan tutkimuksesta:<\/p>\n

 <\/p>\n

Tartigrades ei ehk\u00e4 vaikuta kiinnostavalta tutkimuskohteelta. Kun kuitenkin kysyt oikean kysymyksen, voit l\u00f6yt\u00e4\u00e4 jotain h\u00e4mm\u00e4stytt\u00e4v\u00e4\u00e4, kuten el\u00e4inten supervoimia.<\/p>\n

Innostuitko Kuniedan tieteellisest\u00e4 artikkelista? No, varmista, ett\u00e4 tutkijat innostuvat my\u00f6s sinun tutkimuksestasi!<\/p>\n
