Skeletal muscle myoblasts: GATA4-Wt, -KO, -OE; day 0, 3

ABSTRACT: Gene expression in satellite cell-derived primary myoblasts islolated from Gata4-loxP mice. Myoblasts were infected with nLacZ for control (Wt), Cre recombinase to knockout GATA4 (KO), or GATA4 expression vector to overexpress GATA4 (OE). Infected myoblasts were cultured in growth medium (day 0) then differentiated into myotubes in differentiation medium for 3 days (day 3). Total 18 samples. Three replicates in each myoblast; GATA4-Wt, -KO, and -OE myoblasts at day 0 and day 3.

Cardiac transcription factors in HL-1 cells: gene expression and genome binding profiling

Project description:[1] Gene expression profiling in Gata4, Mef2a knockdown in HL-1 cells. HL-1 cells infected with adenovirus expressing either control siRNA or Gata4, and Gata4 & Mef2a siRNA. [2] Genome-wide maps of cardiac transcription factors binding region in HL-1 cells. We performed bio-ChIP-seq using streptavidin beads immunoprecipitation of biotinylated 5 cardiac transcription factors (fbio) and P300 antibody ChIP-seq. We used a dox-inducible dual adenovirus system to express biotinylated Core Cardiac TFs in HL1. One adenovirus expressed the dox-activated reverse tet activator protein (rtTA) and the E. coli biotinylating enzyme BirA from the cardiac specific rat troponin T promoter. The second virus expressed a Core Cardiac TF fused to a C-terminal flag-bio epitope tag, where bio is the 15 amino acid substrate for BirA. This in vivo biotinylation approach permits pulldown of different factors to be performed under identical, stringent conditions, and circumvents limitations posed by available antibodies. We titrated adenovirus and dox doses to express GATA4flbio and MEF2Aflbio at near endogenous levels. The same conditions were then used to express SRFflbio, TBX5flbio, and NKX2-5flbio.

Transcriptome-wide Regulation of Splicing and mRNA Localization by Muscleblind Proteins

Project description:The Muscleblind-like (Mbnl) family of RNA-binding proteins plays important roles in muscle and eye development and in Myotonic Dystrophy (DM), where expanded CUG or CCUG repeats functionally deplete Mbnl proteins. We identified transcriptome-wide functional and biophysical targets of Mbnl proteins in brain, heart, muscle, and myoblasts using RNA sequencing and crosslinking/immunoprecipitation-sequencing approaches. This analysis identified several hundred splicing events whose regulation depended on Mbnl function, in a pattern indicative of functional interchangeability between Mbnl1 and Mbnl2. A nucleotide resolution RNA map associated repression or activation of exon splicing with Mbnl binding near either 3' splice site or near the downstream 5' splice site, respectively. Transcriptomic analysis of sub-cellular compartments uncovered a global role for Mbnls in regulating localization of mRNAs encoding membrane, synaptic and other proteins in both mouse and Drosophila cells, and Mbnls also contribute to protein secretion. These findings hold several new implications for DM pathogenesis. To assess global functions of Muscleblind proteins, RNA-Seq was performed using WT and Mbnl1 KO brain, heart, and muscle (5 mice each). Additionally, C2C12 mouse myoblasts were depleted of Mbnl1, Mbnl2, or both. Subcellular fractionation experiments were performed to analyze mRNA localization following depletion of Mbnl1 and Mbnl2 in C2C12 mouse myoblasts, and following depletion of Mbnl in Drosophila S-2R+ cells. CLIP-Seq was also performed against Mbnl1 in mouse brain, heart, muscle, and C2C12 myoblasts. Finally, ribosome footprinting was performed with C2C12 mouse myoblasts that were depleted of Mbnl1, Mbnl2, or both.

Parsing the roles of transcription factors Gata4 and Gata6 in adult cardiac hypertrophic responses

Project description:Cardiac hypertrophy is regulated by the zinc finger-containing DNA binding factors Gata4 and Gata6, both of which are required to mount a productive growth response of the adult heart. To determine if Gata4 and Gata6 are redundant or have non-overlapping roles, we performed cardiomyocyte-specific conditional gene deletions for Gata4 and Gata6 in conjunction with reciprocal replacement with a transgene encoding either Gata4 or Gata6, during the pressure overload response. We determined that Gata4 and Gata6 play a redundant and dosage-sensitive role in programming the hypertrophic growth response itself following pressure overload stimulation. However, non-redundant functions were identified as functional decompensation induced by either Gata4 or Gata6 deletion was not rescued by the reciprocal transgene, and only Gata4 heart-specific deletion produced a reduction in capillary density after pressure overload. Gene expression profiling from hearts of these gene-deleted mice showed both overlapping and unique transcriptional codes, with Gata4 exhibiting the strongest impact. These results indicate that Gata4 and Gata6 play a dosage-dependent and semi-redundant role in programming cardiac hypertrophy, but that each has a unique role in maintaining cardiac homeostasis and adaptation to injury that cannot be compensated by the other. Microarray-bassed gene expression profiling identified overlapping, distinct, and quantitatively/differentially regulated classes of Gata4 or Gata6 regulated genes. To determine if Gata4 and Gata6 are redundant or have non-overlapping roles in programming cardiac hypertrophic responses and adaptation to stress or injury, we performed cardiomyocyte-specific conditional gene deletions for Gata4 and Gata6 in conjunction with reciprocal replacement with a transgene encoding either Gata4 or Gata6, during the pressure overload response.
