Transcriptome analysis of human, IPSC-derived cardiomyocytes transfected with siRNA against frataxin vs cells transfect with control siRNA.

Friedreich ataxia is a neuro and cardio degenerative disease, caused by progressive, decreased expression of the frataxin gene (FXN). Hyperthrophic cardiomyopathy is the major cause of early mortality. We used four different lines of human, Induced Pluripotent Stem Cells derived- cardiomyocytes which were transfected with an siRNA against frataxin post-differentiation. Trascriptome analysis of cells in which frataxin was knocked down vs cells transfected with a si control RNA allowed the identification of novel pathways that may contribute to the pathogenesis of the disease.
