Transcriptomic analysis of ethanol, DMSO, I-CBP112 and C646 treatment on mouse embryonic fibroblasts (MEFs) during direct cardiac reprogramming

ABSTRACT: Direct cardiac reprogramming represents an attractive way of reversing heart damage caused by myocardial infarction. Yet, it is still in pre-clinical stage mainly due to the lack of efficacy with current transdifferentiation protocols. Here, we describe that dimethyl sulfoxide (DMSO) is capable of augmenting direct cardiac reprogramming in vitro. Treatment of Gata4, Hand2, Mef2c and Tbx5 (GHMT) - transduced mouse embryonic fibroblasts (MEFs) with 1% DMSO induced ~5 fold increase in the percentage of Myh6-mCherry+ cells, and significantly increased the global expression of cardiac genes. Transcriptomic studies were carried out to explore the underlying mechanism of how DMSO may enhance cardiac transdifferentiation.

Global gene expression in adult cardiac fibroblasts transduced with cardiac transcription factor

Project description:Four transcription factors, GATA4, Hand2, MEF2C, Tbx5 (GHMT) activated cardiac gene expression in cardiac fibroblasts, suggesting that these factors are able to reprogram fibroblasts toward a cardaic cell fate. Total RNA isolated from adult cardiac fibroblasts transduced with empty retroviral vector or GHMT-retroviruses for 2, and 4 weeks.

Gene expression profiles of mouse embryonic fibroblasts (MEFs), induced cardiomyocytes (iCMs) and heart.

Project description:Global gene expression patterns of the iCMs shift from a MEF state toward a cardiac-like phenotype by Gata4/Mef2c/Tbx5 (GMT) or GMT/Hand2 (GHMT) transduction at 2 and 4 weeks after transduction (2W, 4W). Hand2 upregulated a panel of cardiac genes and suppressed cell cylce genes during cardiac reprogramming.

Analysis of transcriptomes during cardioac reprogramming by RNA-deep Sequencing

Project description:Fibroblasts can be reprogrammed into cardiomyocyte-like cells by overexpressing transcription factors, GATA4, Hand2, Mef2C and Tbx5 (GHMT). A83-01, an inhibitor of ALK4, ALK5 and ALK7 and two microRNA, miR-1 and miR-133 increase the efficiency of cardiac reprogramming. RNA_Seq was performed to anyalyze effects of these factors on gene expression. Total RNAs were prepared from mouse embryonic fibroblasts (MEFs); Reprogramming fibroblasts including MEFs transduced with retroviruses encoding GHMT, MEFs transduced with with retroviruses encoding GHMT plus miR-1 and miR-133 (GHMT2m), MEFs transduced with with retroviruses encoding GHMT2m treated with A83-01, at day 7 after viral transduction; and neonatal mouse cardiomyocytes (NMCMs).

Dynamics of H3K4me2 during cardiac lineage reprogramming

Project description:During reprogramming of fibroblasts into cardiomyocyte-like cells by overexpression of transcription factors, GATA4, Hand2, Mef2C and Tbx5 (GHMT), H3K4Me2, an active histone code, shifts from fibroblast-exclusive peaks to cardiomyocyte-exclusive peaks. Important cardiac genes are gradually marked by this active histone marker. Mouse embryonic fibroblasts (MEFs) and neonatal mouse ventricular cardiomyocytes (NMVMs) represent fibroblasts and cardiomyocytes, respectively. Chromatins harvested from MEFs infected with retroviruses carrying GHMT at day 3, day 5, day 7 post-viral infection were prepared for immunoprecipitation.

Akt1/Protein Kinase B Enhances Transcriptional Reprogramming of Fibroblasts to Functional Cardiomyocytes

Project description:Conversion of fibroblasts to functional cardiomyocytes represents a potential approach for restoring cardiac function following myocardial injury, but the technique thus far has been slow and inefficient. To improve the efficiency of reprogramming fibroblasts to cardiac-like myocytes (iCMs) by cardiac transcription factors (Gata4, Hand2, Mef2c, and Tbx5=GHMT), we screened 192 protein kinases and discovered that Akt/protein kinase B dramatically accelerates and amplifies this process. Approximately 50% of reprogrammed fibroblasts displayed spontaneous beating after three weeks of induction by Akt plus GHMT. Furthermore, addition of Akt1 to GHMT evoked a more mature cardiac phenotype for iCMs, as seen by enhanced polynucleation, cellular hypertrophy, gene expression, and metabolic reprogramming. Igf1 and Pi3 kinase acted upstream of Akt, whereas mTORC1 and Foxo3a acted downstream of Akt to influence fibroblast-to-cardiomyocyte reprogramming. These findings provide new insights into the molecular basis of cardiac reprogramming and represent an important step toward further application of this technique.
