RNA-Seq transcriptome profiling of human iPS cell-derived cardiomyocytes (hiPSC-CMs) following overexpression (OE) of estrogen-related receptor gamma (ERRg)

Transcriptional regulatory circuits that drive cardiomyocyte maturation are poorly understood. Human iPS cell-derived cardiomyocytes (hiPSC-CMs) have been shown to have fetal cardiomyocyte features in terms of metabolic gene expression profiles. Here we found that in hiPSC-CMs, overexpression of estrogen-related receptor gamma (ERRg) is sufficient to drive cardiomyocyte metabolic maturation programs including the induction of a number of oxidative mitochondrial metabolic genes. Examination of how gene expression levels are changed by OE ERRg compared to OE GFP in hiPSC-CMs in triplicate.
