Project description:We created mice, which are deficient for Myc specifically in cardiac myocytes by crossing crossed Myc-floxed mice (Mycfl/fl) and MLC-2VCre/+ mice. Serial analysis of earlier stages of gestation revealed that Myc-deficient mice died prematurely at E13.5-14.5. Morphological analyses of E13.5 Myc-null embryos showed normal ventricular size and structure; however, decreased cardiac myocyte proliferation and increased apoptosis was observed. BrdU incorporation rates were also decreased significantly in Myc-null myocardium. Myc-null mice displayed a 3.67-fold increase in apoptotic cardiomyocytes by TUNEL assay. We examined global gene expression using oligonucleotide microarrays. Numerous genes involved in mitochondrial death pathways were dysregulated including Bnip3L and Birc2. Keywords: wildtype vs Myc-null

Project description:Direct conversion of cardiac fibroblast into functional induced cardiomyocytes by forced expression of three cardiac transcription factors, Mef2c, Gata4, and Tbx5, holds great promise for regenerative medicine. Cardiac reprogramming consists of waves of transcription remodeling events, including the fast acquisition of cardiac program and the gradual loss of fibroblast program. However, how this transcription remodeling was driven by the upstream chromatin landscape is still unclear. In this study, we performed single-cell ATAC-seq on Day 3 cardiac reprogramming cells and unveiled networks of transcription factors (TFs) playing a pivotal role in the shift of chromatin accessibility during the early stage of cardiac reprogramming. Moreover, integration analysis of scRNA-seq and scATAC-seq lead to the identification of active TFs function as barriers to cardiac reprogramming.

Hearts were taken from wide type and Myc-null Mouse embryos at E13.5 under the dissecting scope. Cardiac myocyte RNA was isolated using TRIZOL®Reagent Total RNA (100 ng) was hybridized to the Sentrix® MouseRef-8 Expression BeadChip that contains probes for ~24,000 transcripts. GeneChips were scanned using the Hewlett-Packard GeneArray Scanner G2500A. The data were analyzed with Illumina Inc. BeadStudio version 1.5.0.34 and normalized by rank invariant method.

Project description:Direct cardiac reprogramming converts fibroblasts into induced cardiomyocytes (iCMs) with the minimal combination of transcription factors, Gata4 (G), Mef2c (M), and Tbx5 (T). However, the induction of functional mature iCMs is inefficient and the mechanisms remain elusive. Mef2c is a central transcription factor in direct cardiac reprogramming. We investigated the effect of Mef2c isoforms(M1, M2, M6) and transcriptional activity (M2TAD) on cardiac reprogramming on cardiac reprogramming. Then, we found that the active form of Mef2c evoked epigenetic remodeling cooperating with p300 and promoted the maturation of iCMs.
