Weizmann Bilim Enstit\u00fcs\u00fc\u2019nde g\u00f6rev yapan biyolog Uri Alon, uzun \u00f6m\u00fcrle ilgili ders kitaplar\u0131nda yer alan ve ya\u015fam s\u00fcresinin yakla\u015f\u0131k y\u00fczde 20\u2019sinin genetik fakt\u00f6rlere ba\u011fl\u0131 oldu\u011funu \u00f6ne s\u00fcren g\u00f6r\u00fc\u015f\u00fc uzun s\u00fcredir sorguluyordu. Bu durum, ya\u015fam s\u00fcresinin geri kalan b\u00fcy\u00fck b\u00f6l\u00fcm\u00fcn\u00fc hangi fakt\u00f6rlerin belirledi\u011fi ve genetik ara\u015ft\u0131rmalar\u0131n ne kadar anlaml\u0131 oldu\u011fu sorular\u0131n\u0131 g\u00fcndeme getirdi.<\/p>\n\n\n\n

Washington Post<\/strong>‘un haberine g\u00f6re; Alon, karma\u015f\u0131k biyolojik sorunlar\u0131 anlamak i\u00e7in matematiksel modellerden yararlan\u0131yor. Kendisi ve ekibi, insan ya\u015fam s\u00fcresini etkileyen fakt\u00f6rleri yeniden de\u011ferlendirmek amac\u0131yla bir model geli\u015ftirdi. \u00c7al\u0131\u015fma ise Science dergisinde yay\u0131mland\u0131.<\/p>\n\n\n\n

Eski ara\u015ft\u0131rmalar neye dayan\u0131yordu?<\/h2>\n\n\n\n

Ya\u015fam s\u00fcresinin ne kadar\u0131n\u0131n kal\u0131tsal oldu\u011funu belirlemeye y\u00f6nelik \u00f6nceki \u00e7al\u0131\u015fmalar, b\u00fcy\u00fck \u00f6l\u00e7\u00fcde 19. y\u00fczy\u0131l\u0131n sonlar\u0131nda do\u011fan \u0130skandinav ikizlerine dayan\u0131yordu. Ancak bu d\u00f6nemde, ya\u015flanmaya ba\u011fl\u0131 olmayan \u201cd\u0131\u015fsal\u201d \u00f6l\u00fcmler (kazalar, \u015fiddet ve enfeksiyonlar gibi) olduk\u00e7a y\u00fcksekti.<\/p>\n\n\n\n

Alon ve ekibi, 1900\u20131935 y\u0131llar\u0131 aras\u0131nda do\u011fan \u0130sve\u00e7li ikizlere ait verileri analiz ederek bu d\u0131\u015fsal \u00f6l\u00fcmlerin, genetik etkinin g\u00f6zlemlenmesini zorla\u015ft\u0131rd\u0131\u011f\u0131n\u0131 ortaya koydu.<\/p>\n\n\n\n

Genetik etkinin yeniden hesaplanmas\u0131<\/h2>\n\n\n\n

Geli\u015ftirdikleri modelle d\u0131\u015fsal \u00f6l\u00fcmleri d\u0131\u015flad\u0131klar\u0131nda, ya\u015fam s\u00fcresinin kal\u0131tsal etkisinin \u00f6nceki tahminlerden daha y\u00fcksek oldu\u011funu ve yakla\u015f\u0131k y\u00fczde 50 seviyesine ula\u015ft\u0131\u011f\u0131n\u0131 tespit ettiler. Bu bulgu, genetik ve \u00e7evresel fakt\u00f6rlerin ya\u015fam s\u00fcresi \u00fczerindeki etkisinin san\u0131landan daha dengeli olabilece\u011fini g\u00f6steriyor.<\/p>\n\n\n\n

Tarihi ko\u015fullar neden \u00f6nemli?<\/h2>\n\n\n\n

Ara\u015ft\u0131rmaya g\u00f6re eski \u00e7al\u0131\u015fmalar tamamen yanl\u0131\u015f de\u011fil; ancak farkl\u0131 bir d\u00f6nemin ko\u015fullar\u0131n\u0131 yans\u0131t\u0131yor. 19. y\u00fczy\u0131l\u0131n sonlar\u0131nda insanlar \u00e7o\u011funlukla zat\u00fcrre ve t\u00fcberk\u00fcloz gibi hastal\u0131klar nedeniyle erken ya\u015flarda hayat\u0131n\u0131 kaybediyordu. Bu nedenle o d\u00f6nem i\u00e7in genetik fakt\u00f6rlerin ya\u015fam s\u00fcresi \u00fczerindeki etkisi s\u0131n\u0131rl\u0131 g\u00f6r\u00fcn\u00fcyordu.<\/p>\n\n\n\n

Genetik mi, \u00e7evre mi?<\/h2>\n\n\n\n

\u00c7al\u0131\u015fmaya dahil olmayan uzmanlar da bulgulara dikkat \u00e7ekiyor. T\u0131p alan\u0131ndaki ilerlemelerin, ayn\u0131 genetik ge\u00e7mi\u015fe sahip bireylerin ya\u015fam s\u00fcrelerini \u00f6nemli \u00f6l\u00e7\u00fcde de\u011fi\u015ftirebildi\u011fi belirtiliyor. \u00d6rne\u011fin kalp hastal\u0131klar\u0131 gibi durumlarda modern tedaviler, ya\u015fam s\u00fcresini ciddi \u015fekilde uzatabiliyor.<\/p>\n\n\n\n

Uzmanlara g\u00f6re genetik fakt\u00f6rler \u00f6zellikle ileri ya\u015flarda daha belirleyici hale geliyor. 105\u2013110 ya\u015f\u0131na kadar ula\u015fan bireylerde genetik etkiler daha bask\u0131n olurken, ortalama bireylerde ya\u015fam s\u00fcresi; beslenme, egzersiz, sa\u011fl\u0131k hizmetlerine eri\u015fim ve sosyoekonomik ko\u015fullar gibi \u00e7evresel etkenlerle \u015fekilleniyor.<\/p>\n\n\n\n

Ya\u015fam tarz\u0131n\u0131n etkisi<\/h2>\n\n\n\n

Sa\u011fl\u0131kl\u0131 ya\u015fam al\u0131\u015fkanl\u0131klar\u0131n\u0131n ya\u015fam s\u00fcresine katk\u0131 sa\u011flayabilece\u011fi, ancak bu etkinin genetik bir \u201cba\u015flang\u0131\u00e7 noktas\u0131\u201d etraf\u0131nda s\u0131n\u0131rl\u0131 kald\u0131\u011f\u0131 ifade ediliyor. Buna kar\u015f\u0131n sigara, a\u015f\u0131r\u0131 alkol t\u00fcketimi ve k\u00f6t\u00fc beslenme gibi olumsuz al\u0131\u015fkanl\u0131klar ya\u015fam s\u00fcresini ciddi \u00f6l\u00e7\u00fcde k\u0131saltabiliyor.<\/p>\n\n\n\n

Ara\u015ft\u0131rma, ya\u015fam s\u00fcresinin tek bir fakt\u00f6re ba\u011fl\u0131 olmad\u0131\u011f\u0131n\u0131; genetik ve \u00e7evresel etkenlerin birlikte belirleyici oldu\u011funu ortaya koyuyor. Bilim insanlar\u0131, genetik varyasyonlar\u0131n daha iyi anla\u015f\u0131lmas\u0131n\u0131n gelecekte ya\u015flanmay\u0131 etkileyebilecek tedavilerin geli\u015ftirilmesine katk\u0131 sa\u011flayabilece\u011fini vurguluyor. Bununla birlikte sa\u011fl\u0131kl\u0131 ya\u015fam al\u0131\u015fkanl\u0131klar\u0131n\u0131n hala \u00f6nemli bir fark yaratt\u0131\u011f\u0131 konusunda g\u00f6r\u00fc\u015f birli\u011fi bulunuyor.<\/p>\n\n\n\n
