MikroRNA kontrolliert Wachstum der Brustdrüse

Max-Planck-Forscher entdecken neuartigen Mechanismus für die Entwicklung von Organen

(PresseBox) (München, )
Hormone, Wachstumsfaktoren und einige andere Proteine sorgen beizeiten für den notwendigen Zuwachs - die Komponenten, die bei Säugern in der Pubertät zum Brustwachstum führen, schienen weitgehend bekannt. Doch sind Hormone und Proteine bei der Brustentwicklung nicht alles, fand jetzt ein Team von Wissenschaftlern aus Göttingen, Frankfurt und Hannover heraus. Sie konnten zeigen, dass winzige Ribonukleinsäure-Moleküle dabei eine Schlüsselrolle spielen. Bei Mäusen, denen das Gen für die mikroRNAs 212 und 132 fehlten, blieb das Wachstum ihrer Brustdrüsen während der Pubertät vollkommen aus. (Nature Genetics, Online-Vorabveröffentlichung 7. November 2010)

Damit haben Wissenschaftler erstmals im Tiermodell gezeigt, dass kleine Ribonukleinsäure-Moleküle (sogenannte mikroRNAs) auch kvs lqp Gtgzsvxyajcamsxq eknp jogjyecw Olqytwpt livzsxjr.
