Cercet\u0103torii au descifrat codul ADN al celui mai longeviv mamifer, o descoperire care, potrivit acestora, \u201earat\u0103 c\u0103 este posibil s\u0103 tr\u0103im mai mult dec\u00e2t durata medie de via\u021b\u0103 uman\u0103\u201d.<\/p>\n

Potrivit\u00a0Express<\/a>, oamenii de \u0219tiin\u021b\u0103 au reu\u0219it s\u0103 descifreze codul ADN al celui mai longeviv mamifer,\u00a0balena de Groenlanda.<\/p>\n

Aceasta poate tr\u0103i mai bine de 200 de ani datorit\u0103 unei proteine numite CIRBP, care ajut\u0103 organismul s\u0103 repare ADN-u<\/a>l<\/a>\u00a0deteriorat. Proteina, denumit\u0103 \u201ecold-inducible RNA-binding protein\u201d (CIRBP), permite uria\u0219ei creaturi marine, care c\u00e2nt\u0103re\u0219te aproximativ 80 de tone, s\u0103 \u021bin\u0103 cancerul la distan\u021b\u0103.<\/p>\n

Dup\u0103 ce au identificat proteina, cercet\u0103torii de la Universitatea Rochester din New York au ad\u0103ugat-o \u00een celule umane \u0219i au descoperit c\u0103 acestea se reparau mai precis. \u00cen plus, atunci c\u00e2nd au introdus proteina \u00een musculi\u021be de o\u021bet (Drosophila), durata lor de via\u021b\u0103 a crescut.<\/p>\n

\n\u201eAceast\u0103 cercetare arat\u0103 c\u0103 este posibil s\u0103 tr\u0103im mai mult dec\u00e2t durata medie de via\u021b\u0103 uman\u0103\u201d, a declarat profesoara Vera Gorbunova, care a condus studiul.<\/p>\n

Lucr\u00e2nd \u00eempreun\u0103 cu cercet\u0103tori din Alaska, echipa de la Rochester a descoperit, de asemenea, c\u0103 temperaturile sc\u0103zute par s\u0103 \u00eembun\u0103t\u0103\u021beasc\u0103 activitatea proteinei CIRBP.<\/p>\n

De\u0219i este prea devreme pentru a spune cum se poate aplica descoperirea la oameni, Gorbunova a sugerat c\u0103 ar merita explorate metodele prin care activitatea proteinei CIRBP din organismul uman ar putea fi stimulat\u0103. <\/p>\n

Ipoteza include posibilitatea ca expunerea la frig \u2014 de exemplu, du\u0219urile reci \u2014 s\u0103 aib\u0103 un efect benefic.\n<\/p>\n

\u201eExist\u0103 mai multe moduri de a \u00eembun\u0103t\u0103\u021bi men\u021binerea integrit\u0103\u021bii genomului, iar aici afl\u0103m despre o cale unic\u0103, dezvoltat\u0103 la balenele de Groenlanda, care \u00ee\u0219i cresc semnificativ nivelul acestei proteine\u201d, a explicat cercet\u0103toarea. <\/p>\n

\u201eAcum trebuie s\u0103 vedem dac\u0103 putem dezvolta strategii pentru a activa aceea\u0219i cale \u0219i la oameni.\u201d<\/p>\n

Deocamdat\u0103, aceste idei r\u0103m\u00e2n pur teoretice.<\/p>\n

Cercet\u0103torii au descoperit c\u0103 proteina CIRBP, prezent\u0103 la balenele de Groenlanda, repar\u0103 eficient ADN-ul \u0219i reduce muta\u021biile care duc la cancer, explic\u00e2nd de ce aceste mamifere tr\u0103iesc at\u00e2t de mult. Echipa va testa acum dac\u0103 efectul proteinei poate fi replicat \u0219i la mamifere mai mici, cu via\u021b\u0103 mai scurt\u0103.<\/p>\n","protected":false},"excerpt":{"rendered":"Cercet\u0103torii au descifrat codul ADN al celui mai longeviv mamifer, o descoperire care, potrivit acestora, \u201earat\u0103 c\u0103 este…\n","protected":false},"author":2,"featured_media":34347,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[12],"tags":[7295,14725,32,33,31,36,37,27,74,34,35,25,41,40,38,39,14726,26,28,29,30,71,72,73],"class_list":{"0":"post-34346","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-international","8":"tag-adn","9":"tag-balena","10":"tag-breaking-news","11":"tag-breakingnews","12":"tag-cele-mai-populare-subiecte","13":"tag-featured-news","14":"tag-featurednews","15":"tag-headlines","16":"tag-international","17":"tag-latest-news","18":"tag-latestnews","19":"tag-news","20":"tag-ro","21":"tag-romana","22":"tag-romania","23":"tag-romanian","24":"tag-speranta-de-viata","25":"tag-stiri","26":"tag-titluri","27":"tag-top-stories","28":"tag-topstories","29":"tag-world","30":"tag-world-news","31":"tag-worldnews"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@ro\/115483898248902866","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/posts\/34346","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/comments?post=34346"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/posts\/34346\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/media\/34347"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/media?parent=34346"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/categories?post=34346"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ro\/wp-json\/wp\/v2\/tags?post=34346"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
