Trieste \u00dcniversitesi liderli\u011findeki \u0130talyan bilim adamlar\u0131n\u0131n i\u015fbirli\u011fiyle, bu d\u00fc\u015f\u00fcnd\u00fcr\u00fcc\u00fc ve ikna edici hipotez, kanserin memelilerin kalbine neden bu kadar nadiren sald\u0131r\u0131rken, insanlarda primer kalp t\u00fcm\u00f6rlerinin t\u00fcm muayenelerin yaln\u0131zca y\u00fczde birinde g\u00f6r\u00fcld\u00fc\u011f\u00fcn\u00fc a\u00e7\u0131klamak i\u00e7in ortaya at\u0131ld\u0131.

Science dergisinde yay\u0131nlanan ara\u015ft\u0131rmaya g\u00f6re t\u00fcm\u00f6rlerin b\u00fcy\u00fcmesi kalbin do\u011frudan ya da ona metastaz yapmas\u0131 o kadar nadir bir durum ki, mikro\u00e7evresinde bu olay\u0131 zorla\u015ft\u0131ran bir \u015fey olmal\u0131.<\/p>\n
Bu nedenle Giulio Ciucci ve Serena Zacchigna’n\u0131n koordine etti\u011fi bir grup bilim insan\u0131, hem nakledilen hem de orijinal kalbe t\u00fcm\u00f6r h\u00fccrelerini enjekte ederek, atamayan, ancak kan damarlar\u0131 olan ve iyi oksijenlenmi\u015f farelerin boyunlar\u0131na, hem nakledilen hem de orijinal kalbe t\u00fcm\u00f6r h\u00fccreleri enjekte ederek nakledildi.<\/p>\n
Atan kalpte iki hafta kald\u0131ktan sonra kanser h\u00fccreleri yok oldu. \u00e7o\u011falarak sa\u011fl\u0131kl\u0131 h\u00fccrelerin \u00e7o\u011funun yerini ald\u0131. Nakledilen kalpte dokunun yaln\u0131zca y\u00fczde birka\u00e7\u0131n\u0131 kaplam\u0131\u015flard\u0131.<\/p>\n
\u0130kinci bir deneyde, bilim insanlar\u0131 laboratuvarda komut \u00fczerine atacak \u015fekilde tasarlanm\u0131\u015f bir fare kalbi yeti\u015ftirdiler ve t\u00fcm\u00f6r h\u00fccrelerinin, organ\u0131n atan k\u0131sm\u0131na g\u00f6re organ\u0131n statik k\u0131sm\u0131nda daha fazla yay\u0131ld\u0131\u011f\u0131n\u0131 g\u00f6rd\u00fcler.<\/p>\n
Buradaki fikir, kalbin kan\u0131 pompalamak i\u00e7in maruz kald\u0131\u011f\u0131 yo\u011fun mekanik stresin, t\u00fcm\u00f6r h\u00fccrelerinin yay\u0131lmas\u0131n\u0131 durdurdu\u011fudur. Ayr\u0131ca bu mekanizma, h\u00fccreleri y\u0131lda yakla\u015f\u0131k y\u00fczde bir oran\u0131nda yenilendi\u011finden, kalbin kendini yenileme konusundaki zay\u0131f kapasitesinin de alt\u0131nda yat\u0131yor olabilir.<\/p>\n
Mekanik sinyalleri tan\u0131mlayan ve bunlar\u0131 h\u00fccre \u00e7ekirde\u011fine ileten Nesprin-2 proteininin, stres varl\u0131\u011f\u0131nda h\u00fccre b\u00fcy\u00fcmesini engellemede \u00e7ok \u00f6nemli g\u00f6r\u00fcnd\u00fc\u011f\u00fcnden, bu ke\u015fif, mekanik zorlamadan yararlanan yeni kanser kar\u015f\u0131t\u0131 tedaviler \u00f6nerebilir.<\/p>\n
Bu \u00e7al\u0131\u015fma ayn\u0131 zamanda yara dokusunun neden yaln\u0131zca da\u011f\u0131ld\u0131\u011f\u0131n\u0131 a\u00e7\u0131klayarak kalp fibrozu i\u00e7in de \u00e7\u0131kar\u0131mlar yapabilir. kalbin baz\u0131 yerlerinde var, di\u011ferlerinde de\u011fil.\/tesheshi.com\/<\/p>\n
