Neue Erkenntnisse über die Regulation der Insulinproduktion des Körpers bei Insulinresistenz, Ursache für die Entstehung von Diabetes Typ-2, haben Forscher des Max-Delbrück-Centrums für Molekulare Medizin (MDC) Berlin-Buch gewonnen. Sudhir G. Tattikota, Thomas Rathjen und Dr. Matthew Poy identifizierten einige Komponenten eines Signalwegs, die den Beta-Zellen der Bauchspeicheldrüse helfen, auf den Insulinbedarf des Körpers flexibel zu reagieren. Erstmals konnten sie damit bei übergewichtigen Mäusen zeigen, wie die insulinproduzierenden Beta-Zellen diesen microRNA (miRNA)-Signalweg nutzen, um Zellwachstum und die Ausschüttung von Insulin zu steuern (Cell Metabolism, http://dx.doi.org/10.1016/j.cmet.2013.11.015)*.
