TranscriptomicsmicroRNA-1 negatively regulates expression of the hypertrophy-associated genes calmodulin and Mef2a
Calcium signaling is a central regulator of cardiomyocyte growth and function. Calmodulin is a critical mediator of calcium signals. Because the amount of calmodulin within cardiomyocytes is limiting, precise regulation of calmodulin expression may be an important for regulation of calcium signaling...

TranscriptomicsTranscription profiling of hearts from mice heterozygous for Gata4 mutation (G4D) to investigate the significance of Gata4 in regulating postnatal heart function and in regulating the hypertrophic response of the heart to pathological stress.
An important event in the pathogenesis of heart failure is the development of pathological cardiac hypertrophy. In cultured cardiac cardiomyocytes, the transcription factor Gata4 is required for agonist-induced cardiomyocyte hypertrophy. We hypothesized that in the intact organism Gata4 is an import...
