Abstract
The pathogenic role of noncoding microRNA (miR, miRNA) has been demonstrated for several disease conditions in the heart. The underlying molecular mechanisms have been deciphered for numerous miRs that are deregulated as a result of cardiac stress. Innovative therapeutic strategies based on antifibrotic, antihypertrophic, or proangiogenic effects of miRNAs are being currently developed to improve the function of the failing heart. Identifying a safe and efficient miR-based strategy remains challenging, yet these novel approaches offer enormous potential for the treatments for heart failure. In this review we highlight the latest development in the cardiac miRNA field.
Zusammenfassung
Die Beteiligung nichtkodierender Mikro-RNA (miR, miRNA) an pathologischen Veränderungen wurde für verschiedene Herzerkrankungen gezeigt. Für einzelne, nach kardialem Stress herauf- oder herunterregulierte miR sind die zugrunde liegenden molekularen Mechanismen aufgeklärt worden. Neuartige miR-basierte Therapiestrategien (antifibrotisch, antihypertroph oder proangiogen) zielen nun darauf, funktionale Parameter des insuffzienten Myokards zu verbessern. Die Identifizierung geeigneter Kandidaten-miR ist eine große Herausforderung, allerdings weisen diese Therapieoptionen auch ein großes Potenzial für die Behandlung der Herzinsuffizienz auf. In diesem Übersichtsartikel werden miR-basierte therepeutische Strategien vorgestellt.
