Transcription profiling of two transgenic models familial hypertrophic cardiomyopathy mice vs wild type and non transgenic controls using pooled and non pooled heart extracts to identify differences in gene expression in FHC

ABSTRACT: Familial hypertrophic cardiomyopathy (FHC) is a disease characterized by ventricular hypertrophy, fibrosis, and aberrant systolic and/or diastolic function. We previously developed two transgenic mouse models that carry FHC associated mutations in alpha-tropomyosin (TM): FHC alpha-TM175 mice show patchy areas of mild ventricular disorganization and limited hypertrophy; whereas FHC alpha-TM180 mice exhibit severe hypertrophy and fibrosis and die within 6 months. To obtain a better understanding of the molecular mechanisms associated with the early onset of cardiac hypertrophy, we conducted a detailed comparative analysis of gene expression in 2.5-month-old control and FHC alpha-TM175 and alpha-TM180 ventricular tissue. Results show that 754 genes (from a total of 22,600) were differentially
