Induzierte pluripotente Stammzellen verraten Krankheitsursachen

(PresseBox) (Heidelberg, )
Induzierte pluripotente Stammzellen (iPSC) sind geeignet, um die verantwortlichen Gene zu entdecken, die komplexen und auch seltenen genetischen Erkrankungen zugrunde liegen. Dies konnten Wissenschaftler vom Deutschen Krebsforschungszentrum (DKFZ) und vom Europäischen Laboratorium für Molekularbiologie (EMBL) gemeinsam mit internationalen Partnern erstmals mit einer Untersuchung an iPS-Zelllinien von fast tausend Spendern zeigen.

Im menschlichen Erbgut sind bis heute Zehntausende von winzigen Bauplan-Abweichungen (SNPs, single nuceotide polymorphisms) identifiziert, die mit bestimmten Erkrankungen im Zusammenhang stehen. Viele dieser genetischen Varianten liegen nicht in den proteinkodierenden Bereichen der Gene, sondern betreffen regulatorische Abschnitte des Erbguts. Deshalb suchen Wissenschaftler, ob und in welchen Geweben diese Mini-Varianten oqp Qonikxortxhax dv czb Kyauybqay hkiiogzywl Kdff jx Kpojzifxbb hzqfbjzu arfyil witbps.
