Superputerile tartigradelor sunt un subiect \u00een vog\u0103 \u00een \u00eentreaga lume. Cu toate acestea, tocmai c\u00e2nd credeai c\u0103 natura nu poate deveni mai nebun\u0103, te surprinde din nou.<\/p>\n

Tartigradele sunt deja cunoscute ca fiind cele mai rezistente animale de pe P\u0103m\u00e2nt. Ele au primit aceast\u0103 etichet\u0103 datorit\u0103 rezisten\u021bei lor la radia\u021bii, presiuni ridicate \u0219i temperaturi extreme. Nu este o surpriz\u0103 faptul c\u0103 acest mic animal a declan\u0219at o serie de noi \u00eentreb\u0103ri cu privire la modul \u00een care s-ar fi putut \u00eent\u00e2mpla evolu\u021bia.<\/p>\n

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

S\u0103pt\u0103m\u00e2na aceasta, o nou\u0103 cercetare publicat\u0103 \u00een revista Nature<\/a>, a dezv\u0103luit mult mai multe despre superputerile tartigradelor.<\/p>\n

Dup\u0103 ce au secven\u021biat genomul tartigradelor, Takekazu Kunieda \u0219i echipa sa de cercet\u0103tori au identificat o protein\u0103 care protejeaz\u0103 ADN-ul atunci c\u00e2nd este supus radia\u021biilor. Aceast\u0103 protein\u0103 poate fi g\u0103sit\u0103 doar la tartigrade. Cu toate acestea, Kunieda studiaz\u0103 \u00een prezent modul \u00een care aceea\u0219i protein\u0103 poate fi introdus\u0103 la oameni \u0219i poate proteja ADN-ul uman.<\/p>\n

\u00a0\"Este uimitor s\u0103 vezi c\u0103 o singur\u0103 gen\u0103 este suficient\u0103 pentru a \u00eembun\u0103t\u0103\u021bi, \u00eentr-o cultur\u0103 de celule umane, toleran\u021ba acestora la radia\u021bii. Credem c\u0103 aceast\u0103 protein\u0103 poate func\u021biona ca un scut fizic pentru a proteja ADN-ul uman de atacuri\"<\/p><\/blockquote>\n

Secretul superputerilor tartigradelor este capacitatea lor de a rezista la o deshidratare extrem\u0103. Tartigradele sunt capabile s\u0103 supravie\u021buiasc\u0103 cu doar 1% de ap\u0103 \u0219i apoi s\u0103 revin\u0103 la via\u021b\u0103 ca \u0219i cum nimic nu s-ar fi \u00eent\u00e2mplat. Potrivit lui Kunieda, tartigradele \u00ee\u0219i \u00eempart ADN-ul \u00een buc\u0103\u021bi mici \u0219i \u00ee\u0219i reduc activitatea de via\u021b\u0103 la 0,01%. Odat\u0103 hidratat din nou, ADN-ul se repar\u0103 \u0219i activitatea lor vital\u0103 revine la 100%.<\/p>\n

Secven\u021bierea genomului sugereaz\u0103, de asemenea, c\u0103 majoritatea genelor tartigrade au provenit de la alte animale printr-un proces numit \"transfer orizontal de gene\". Iat\u0103 un infografic care rezum\u0103 cercet\u0103rile lui Kunieda:<\/p>\n

Tartigradele nu par a fi un obiect de studiu interesant. Cu toate acestea, atunci c\u00e2nd pui \u00eentrebarea potrivit\u0103, po\u021bi descoperi ceva uimitor, cum ar fi superputerile animalelor.<\/p>\n

V\u0103 sim\u021bi\u021bi entuziasmat de lucrarea \u0219tiin\u021bific\u0103 Kunieda? Ei bine, asigura\u021bi-v\u0103 c\u0103 \u0219i oamenii de \u0219tiin\u021b\u0103 sunt entuziasma\u021bi de cercetarea dumneavoastr\u0103!<\/p>\n
