Exploration of gene expression signature for human coronary artery endothelial cells in response to inhibition of myocyte enhancer factor 2A

ABSTRACT: Myocyte enhancer factor 2A (MEF2A) is a crucial transcritional activator which plays diverse roles in the control of cell growth, survival, apoptosis and inflammation etc. To expore the gene expression signature of human coronary artery endothelial cells (HCAEC) in reponse to inhibition of MEF2A， we have employed whole genome microarray expression profiling as a discovery platform to identify genes with important functional role in HCAEC. Three independent groups of HCAEC transfected with MEF2A specific siRNA were separately performed. Three MEF2A specific siRNA groups were indicated as 1527-1, 1527-2 and 1527-3, and the mixed control group was designated as NC.

MEF2A interactome in striated muscle by an affinity-purification followed by LC-MS-MS

Project description:Myocyte Enhancer Factor 2 (MEF2) proteins are involved in multiple developmental, physiological, and pathological processes in vertebrates. Protein:protein interactions underlie the plethora of biological processes impacted by MEF2A, necessitating a detailed characterization of the MEF2A interactome. A nanobody based affinity-purification/mass spectrometry strategy was employed to achieve this goal. Specifically, the MEF2A protein complexes were captured from myogenic lysates using a GFP-tagged MEF2A protein immobilized with a GBP-nanobody followed by LC-MS/MS proteomic analysis to identify MEF2A interactors.

Dysregulated gene expression in cardiac chambers of adult Mef2a knockout mice

Project description:In this study, we have identified MEF2A-sensitive genes in atrial and ventricular chambers of the adult heart. MEF2A is a member of the myocyte enhancer factor 2 (MEF2) family of transcription factors. MEF2 proteins are expressed in skeletal and cardiac muscle tissues and are conserved across many mammalian species, but the gene programs regulated by MEF2A in adult cardiac chambers are largely unknown. We compared gene expression profiles between WT and Mef2a knockout atria and ventricles from adult mice, and the results identified distinct and overlapping sets of genes sensitive to the loss of MEF2A in the adult heart.

Transcriptional Reversion of Cardiac Myocyte Fate During Mammalian Cardiac Regeneration.

Project description: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. Methods and Results: We derived a core transcriptional signature of injury-induced cardiac myocyte regeneration in mouse by comparing global transcriptional programs in a dynamic model of in vitro and in vivo cardiac myocyte differentiation, in vitro cardiac myocyte explant model, as well as a neonatal heart resection model. The regenerating mouse heart revealed a transcriptional reversion of cardiac myocyte differentiation processes including reactivation of latent developmental programs similar to those observed during de-stabilization of a mature cardiac myocyte phenotype in the explant model. We identified potential upstream regulators of the core network, including interleukin 13 (IL13), which induced cardiac myocyte cell cycle entry and STAT6/STAT3 signaling in vitro. We demonstrate that STAT3/periostin and STAT6 signaling are critical mediators of IL13 signaling in cardiac myocytes. These downstream signaling molecules are also modulated in the regenerating mouse heart. Conclusions: Our work reveals new insights into the transcriptional regulation of mammalian cardiac regeneration and provides the founding circuitry for identifying potential regulators for stimulating heart regeneration.

Myocyte enhancer factor 2A is transcriptionally autoregulated.

Project description:MEF2 (myocyte enhancer factor 2) proteins are a small family of transcription factors that play pivotal roles in striated muscle differentiation, development, and metabolism, in neuron survival and synaptic formation, and in lymphocyte selection and activation. Products of the four mammalian MEF2 genes, MEF2A, MEF2B, MEF2C, and MEF2D, are expressed with overlapping but distinct temporospatial patterns. Toward analysis of MEF2A functions and the determinants of its regulated expression, we have mapped and begun studies of the transcriptional control regions of this gene. Heterogeneous 5'-untranslated regions of MEF2A mRNAs result from use of alternative promoters and splicing patterns. The two closely approximated TATA-less promoters are approximately 65 kb upstream of the exon containing the sole initiation codon. Ribonuclease protection and primer extension assays show that each promoter is active in various adult tissues. A canonical MEF2 site overlies the major promoter 1 transcription start site. This element specifically binds MEF2 factors, including endogenous nuclear MEF2A according to chromatin immunoprecipitation studies, and is critical to MEF2A transcription in myocytes. The site exerts reciprocal control of the alternative promoters, silencing promoter 1 and activating promoter 2 under some conditions. Erk5 and p38 MAPK signaling stimulate MEF2A expression by activating both promoters from the MEF2 element. MEF2A transcription is therefore subject to positive or negative regulation by its protein products, depending on signaling activities that influence MEF2 factor trans-activity. The sole MEF2 gene of the cephalochordate amphioxus has a similar regulatory region structure, suggesting that this mode of autoregulatory control is conserved among higher metazoan MEF2 genes.

Single cell RNA-Seq of the murine non-myocyte cardiac cellulome

Project description:We characterized single-cell transcriptional profiles of the cardiac non-myocyte cell pool in C57BL/6J mice. The cell preparation we sequenced consisted of metabolically active, nucleated non-myocyte cells from heart ventricles of female and male mice which were depleted of endothelial cells. The goals of this experiment included examining cellular diversity, identifying markers of understudied cell populations, exploring functional roles of different cell types, and characterizing sexual dimorphism in cardiac gene expression.
