However, factors that determine these differences remain largely undefined. Cardiomyocyte-specific COUP- TFII ablation produces ventricularized atria that exhibit ventricle-like action potentials, increased cardiomyocyte size, and development of extensive T-tubules. We used microarrays to examine the molecular profile of cardiomyocyte-specific COUP-TFII knockout adult atria in comparison with that of normal atria. We extracted RNA from mutant right atria, control right atria and control ventricles from 2 months old adult mice, followed by gene expression profiling using Affymetrix microarrays.", "source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-46496", "species": "mouse", "sample_source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-46496/samples/"}
