Okyanuslarda ya\u015fayan ve “\u00f6l\u00fcms\u00fcz denizanas\u0131” olarak an\u0131lan bu canl\u0131dan elde edilen verilerin, Alzheimer, inme, kalp krizi ve ya\u015fa ba\u011fl\u0131 g\u00f6rme kay\u0131plar\u0131 gibi hastal\u0131klar\u0131n tedavisinde yeni y\u00f6ntemlere kap\u0131 aralamas\u0131 hedefleniyor.<\/p>\n

Texas A&M \u00dcniversitesi Deniz Biyolo\u011fu Maria Miglietta’n\u0131n y\u00fcr\u00fctt\u00fc\u011f\u00fc laboratuvar testlerinde s\u00f6z konusu canl\u0131lar\u0131n a\u00e7 b\u0131rak\u0131lma, kaynat\u0131lma, kesilme ya da a\u015f\u0131r\u0131 tuzlu veya tatl\u0131 suya maruz kalma gibi zorlu \u015fartlarda dahi \u00f6lmedi\u011fi kaydedildi.<\/p>\n

\u00a0<\/p>\n

Bu t\u00fcr stres unsurlar\u0131yla kar\u015f\u0131la\u015fan yeti\u015fkin denizanas\u0131, tabana \u00e7\u00f6kerek k\u00fcre bi\u00e7iminde bir h\u00fccre y\u0131\u011f\u0131n\u0131na d\u00f6n\u00fc\u015f\u00fcyor; ard\u0131ndan bir ila \u00fc\u00e7 g\u00fcn i\u00e7inde erken ya\u015fam evresi say\u0131lan “polip” formuna geri d\u00f6nerek y\u00fczlerce yeni denizanas\u0131 \u00fcretebilen bir koloni meydana getiriyor.<\/p>\n

\u00a0<\/p>\n

Yeti\u015fkin bir canl\u0131n\u0131n yeniden erken geli\u015fim evresine d\u00f6nebilmesi hayvanlar aleminde benzersiz bir \u00f6zellik olarak \u00f6ne \u00e7\u0131k\u0131yor.<\/p>\n

\u00a0<\/p>\n

Kertenkele, solucan veya amfibiler kopan uzuvlar\u0131n\u0131 yenileyebilirken hi\u00e7bir t\u00fcr t\u00fcm v\u00fccudunu bebeklik evresine d\u00f6nd\u00fcremiyor.<\/p>\n

\u00a0<\/p>\n

Bu d\u00f6ng\u00fc ilk kez 1992 y\u0131l\u0131nda \u0130talyan bir ara\u015ft\u0131rmac\u0131n\u0131n hafta sonu beslemeyi unuttu\u011fu denizanalar\u0131n\u0131n \u00f6ld\u00fc\u011f\u00fcn\u00fc san\u0131p kapta yeni polipler g\u00f6rmesiyle fark edildi.<\/p>\n

BBC’ye konu\u015fan Salento \u00dcniversitesinden biyolog Stefano Piraino ise bu d\u00f6n\u00fc\u015f\u00fcm\u00fcn, yeti\u015fkin dokular\u0131n k\u00f6k h\u00fccre benzeri bir duruma geri d\u00f6n\u00fcp yeniden farkl\u0131la\u015fmas\u0131n\u0131 sa\u011flayan “transdiferansiyasyon” s\u00fcreciyle ger\u00e7ekle\u015fti\u011fini ortaya koydu.<\/p>\n<\/div>\n
