Project description:Tbx20 is a transcription factor known to play important roles in embryonic and adult mouse heart function. Our goal in this work was to better understand the function of this gene in embryonic (E11.5) mouse cardiomyocytes that form the developing chambers, expanding our knowledge of its role in heart development. To elucidate the role of Tbx20 in mouse cardiomyocytes, we generated conditional Tbx20 knockout and compared 4 samples with 4 samples of wild-type cardiomyocytes. We found evidence of regulation of cell cycle genes by Tbx20, which are involved in proliferation. In addition, Tbx20 seems to bind and regulate an enhancer of CoupTFII in the atrium, a gene involved in atrial development.
Project description:Genome-wide gene expression analysis at different stages of cardiomyocyte differentiation (undifferentiated mouse embryonic stem cells, neonatal mouse cardiomyocytes and adult mouse cardiomyocytes). Results provide important information on the differential expressed genes between undifferentiated mouse embrionic stem cells (mES) and mouse cardiomyocytes (CM) and also between cardiomyocytes from neonatal (CMp) and adult stages (CMa). This dataset allowed us to compare the expression profile of mES, CMp and CMa with the epigenetic profile of histone methylation generated with ChIP-seq experiments. Total RNA was obtained from biological triplicate of undifferentiated mouse embryonic stem cells (mES), neonatal mouse cardiomyocytes (CMp) and adult mouse cardiomyocytes (CMa)
