Wissenschaftler vom Deutschen Krebsforschungszentrum sowie von den Universitäten Cambridge und Edinburgh haben die molekulare Evolution von Tumoren nach der Einwirkung erbgutschädigender Chemikalien durchgespielt. Dabei entdeckten sie, dass die von der Chemikalie ausgelösten Defekte an einzelnen DNA-Bausteinen nicht sofort repariert, sondern über mehrere Runden der Zellteilung weitergegeben werden. Die beiden DNA-Stränge mit ihren voneinander unabhängigen Defekten werden bei der Zellteilung voneinander getrennt, daraus resultieren zwei Tochterzellen mit unterschiedlichen Mutationsprofilen. Bei weiteren Replikationsrunden führen die Schäden immer wieder zu neuen, andersartigen Mutationen. Diese "Schadens-Segregation" führt zu den komplexen Mustern an Mutationen im Tumorgenom. Die Chance, dass dabei tumortreibende Kombinationen an Erbgutdefekten entstehen, jfr viko. Qwdax Lmanobovba ppyzbkhforlrrghr anz Ihhgczchddecjxk fev wu zlf Mtmoyoazmsy Unyibb.
