Global microRNA profiling of the mouse ventricles during development of severe hypertrophic cardiomyopathy and heart failure

ABSTRACT: The study sought to determine the global miRNA profile of ventricles during early and end-stage hypertrophic cardiomyopathy in a severe double mutant mouse model of the disease. MicroRNA expression profiles of ventricles of transgenic mice with a mutation in both the myosin heavy chain gene (MYH7 Arg403Gln) and cardiac troponin I gene (TNNI3 Ser203Gln) and of non-transgenic mice were determined using Rodent TaqMan Low Density miRNA Arrays A v2.0 (TLDA, Life Technologies). MicroRNA profiles were measured at 10 days of age and 16 days of age, in 3 biological replicates. qRT-PCR analysis of microRNAs of ventricles of three transgenic mice and three non-transgenic mice age 10 days, and three transgenic mice and three non-transgenic mice age 16 days. 450 ng RNA was reverse transcribed, without pre-amplification, using TaqMan MicroRNA Reverse Transcription Kit and Megaplex RT Primers rodent pool A (Life Technologies). Complementary DNA (cDNA) was amplified using a TaqMan rodent microRNA A Array v2.0 (Life Technologies) with TaqMan Universal PCR Master Mix on an ABI 7900HT Sequence Detection System.
