(Submitter supplied) Transcriptional regulatory circuits that drive cardiomyocyte maturation during the developmental process are poorly understood. Estrogen-related receptor alpha and gamma (ERRa/g) have been shown to be involved in all aspects of mitochondrial energy production. However, the function of ERR during the cardiac developmental process is not understood well. To examine the role of (ERRa/g), we generated cardiac-specific ERRa/g knockout (KO) mice and found that the KO mice died within 24 hours post-birth. more...

(Submitter supplied) Transcriptional regulatory circuits that drive cardiomyocyte maturation during the developmental process are poorly understood. Estrogen-related receptor alpha and gamma (ERRa/g) have been shown to be involved in all aspects of mitochondrial energy production. However, the function of ERR during the postnatal cardiac developmental process is unclear. To examine the role of (ERRa/g) during postnatal cardiac maturation, we generated inducible cardiac-specific ERRa/g knockdown (KD) mice with adeno-associated virus serotype 9 (AAV9) expressing Cre. more...

(Submitter supplied) Estrogen-related receptor gamma (ERRg) has been shown to control gene expression involved in a broad range of mitochondrial energy metabolism including oxidative phosphorylation, TCA cycle, and fatty acid oxidation. However, ERRg direct targets were not identified in cardiomyocytes. With ERRg ChIP-seq, we found ERRg peaks on the promoter regions of mitochondrial energy metabolic genes as expected. Besides, ERRg extensively distributed the promoter regions of cardiac contractile, ion channels and Ca2+ handling protein genes. more...

(Submitter supplied) 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.

(Submitter supplied) To determine the role of estrogen-related receptor gamma (ERRg) in cardiac myocyte enhancers, we performed ChIP-seq studies with hiPSC-CMs using antibody directed against acetylated histone 3 at lysine residue 27 (H3K27ac), a known active enhancer mark. We found that knocking out ERRg downregulated H3K27ac depositions on several adult cardiac contractile protein and mitochondrial oxidative metabolic genes. more...

(Submitter supplied) To determine the role of estrogen-related receptor alpha and gamma (ERRa/g) on chromatin accessibility, we performed ATAC-seq studies with WT control and ERRa/g KO hiPSC-CMs. We found that ERRa/g activates cardiac chromatin accessibilities in hiPSC-CMs. A subset of the decreased ATAC signals by loss of ERRa/g overlapped ERRg peaks (GSE113760) in hiPSC-CMs, suggesting that ERRg might be directly involved in the activation of cardiac chromatin accessibilities. more...

(Submitter supplied) During the postnatal period in mammals, the cardiac muscle transitions from hyperplasic to hypertrophic growth, the extracellular matrix (ECM) undergoes remodeling, and the heart loses regenerative capacity. While ECM maturation and crosstalk between cardiac fibroblasts (CFs) and cardiomyocytes (CM) have been implicated in neonatal heart development, not much is known about specialized fibroblast heterogeneity and functions in the early postnatal period. more...

(Submitter supplied) Methods: RNA-seq libraries were prepared using the Illumina TruSeq technology. The libraries were quantified and samples were multiplexed in each lane of the flowcell. Cluster generation was performed and then sequenced on the Illumina HiSeq2500 system. Reads were mapped on the Human Genome Reference (GRCh38) and normalized expression table was generated. Results: Among differentially expressed genes, compared with DMSO-treated hiPSC-CMs, 505 genes were upregulated in FM+WY+TID-treated hiPSC-CMs, with 72 genes commonly upregulated in both FM+WY+TID-treated hiPSC-CMs and LV groups and 949 genes were downregulated in FM+WY+TID-treated hiPSC-CMs and 2137 genes were downregulated in LV, with 437 genes downregulated in both FM+WY+TID-treated hiPSC-CMs and LV compared with DMSO-treated hiPSC-CMs . more...

(Submitter supplied) 3 ventricles from E18.5 male mice were pooled for each array. Three arrays per genotype. Title: ERRγ Directs and Maintains the Transition to Oxidative Metabolism in the Post-Natal Heart Abstract: At birth the heart undergoes a critical metabolic switch to transition from a predominant dependence on carbohydrates during fetal life to a greater dependence on postnatal oxidative metabolism. This remains the principle metabolic state throughout life; although pathologic conditions such as heart failure and cardiac hypertrophy reactivate components of the fetal genetic program to increase carbohydrate utilization. more...

(Submitter supplied) We identified two cardiac maturation stimulators from 9,048 compounds using Troponin I1 (TNNI1) and Troponin I3 (TNNI3) double reporter hiPSC-derived CMs. An estrogen-related receptor gamma (ERRγ)-specific agonist increased the size of hiPSC-CMs and their mitochondrial content and enhanced their mitochondrial function. In addition, combination of this agonist with an inhibitor of S-phase kinase-associated protein 2 (SKP2) increased the TNNI3 expression more highly than previous methods and enhanced cardiac maturation-related gene expression profiles.

(Submitter supplied) Rationale: Human pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) provide a platform to identify and characterize factors that regulate the maturation of CMs. The transition from an immature fetal to adult CM state entails coordinated regulation of the expression of genes involved in myofibril formation and OXPHOS among others. Lysine demethylase 5 (KDM5) specifically demethylate H3K4me1/2/3 and have emerged as potential regulators of expression of genes involved in cardiac development and mitochondrial function.Objectives: The purpose of this study is to determine the role of KDM5 in iPSC-CM maturation.Methods and Results: KDM5A, B, and C proteins were mainly expressed in the early post-natal stages and their expressions were progressively downregulated in the postnatal cardiomyocytes and were absent in adult hearts and CMs. more...

Therefore, activation of ERR could be a potential theraputic intervention for heart failure.

(Submitter supplied) Rationale: Neonatal mice have the capacity to regenerate their hearts in response to injury, but this potential is lost after the first week of life. The transcriptional changes that underpin mammalian cardiac regeneration have not been fully characterized at the molecular level. Objective: The objectives of our study were to determine if myocytes revert the transcriptional phenotype to a less differentiated state during regeneration and to systematically interrogate the transcriptional data to identify and validate potential regulators of this process. more...
