Description
During neonatal development, skeletal muscle grows dramatically by myonuclei accretion to existing fibers and hypertophic growth of fibers with protein synthesis. Overall design: To understand molecular mechanism underlying neonatal muscle growth, we used RNAseq to profile the global program of gene expressions especially involved in myoblast fusion, migration, and muscle fiber growth by itself. We used two biological replicates for each time point.

Description
We found that CITED2 is highly expressed in metastatic prostate cancer, and its expression is correlated with poor survival in pateints. In this study, we used an siRNA to decrease CITED2 expression in PC3 cells. A RNA-seq approach was utilized in order to determine global gene expression changes in CITED2 knockdown cells compared to control cells. Overall design: PC3 cells transfected with control siRNAs were used as controls. Cells transfected with siRNAs targeting CITED2 were used as experimental group. Cells were transfected for 72 hr and the analyses were done.

Description
Nasu-Hakola disease (NHD), also designated polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy (PLOSL; OMIM 221770), is a rare autosomal recessive disorder, characterized by progressive presenile dementia and formation of multifocal bone cysts, caused by genetic mutations of DAP12 and TREM2, which constitute a receptor/adapter signaling complex expressed on osteoclasts, dendritic cells, macrophages, and microglia. No Japanese patients with TREM2 mutations have been reported previously. We reported three siblings affected with NHD in a Japanese family. Among them, two died of NHD during the fourth decade of life. The transcriptome was studied in the autopsized brain of one patient. We found a homozygous conversion of a single nucleotide T to C at the second position of intron 3 in the splice-donor consensus site (c.482+2T>C) of the TREM2 gene, resulting in exon 3 skipping. We identified 136 upregulated genes involved in inflammatory response and immune cell trafficking and 188 downregulated genes including a battery of GABA receptor subunits and synaptic proteins in the patients brain.

Description
We found genetic deletion of IKK in mdx cardiomyocytes improved cardiac function and normalized calcium transients. We used microarrays to profile gene expression in hearts of mdx mice with intact IKK signaling and hearts of mdx mice with IKK-deficient cardiomyocytes to identify genes differentially regulated by NF-[kappa]B. signaling in dystrophic hearts.

Description
We conditionally inactivated mouse Cdx2, a dominant regulator of intestinal development, and mapped its genome occupancy in adult intestinal villi. Although homeotic transformation, observed in Cdx2-null embryos, was absent in mutant adults, gene expression and cell morphology were vitally compromised. Lethality was accelerated in mice lacking both Cdx2 and its homolog Cdx1, with exaggeration of defects in crypt cell replication and enterocyte differentiation. Cdx2 occupancy correlated with hundreds of transcripts that fell but not with equal numbers that rose with Cdx loss, indicating a predominantly activating role at intestinal cis-regulatory regions. Integrated consideration of a mutant phenotype and cistrome hence reveals the continued and distinct requirement in adults of a master developmental regulator that activates tissue-specific genes.

Description
As Trypanosoma cruzi, the etiological agent of Chagas disease, multiplies in the cytoplasm of nucleated host cells, infection with this parasite is highly likely to affect host cells. We performed an exhaustive transcriptome analysis of T. cruzi-infected HeLa cells using an oligonucleotide microarray containing probes for greater than 47,000 human gene transcripts. In comparison with uninfected cells, those infected with T. cruzi showed greater than threefold up-regulation of 41 genes and greater than threefold down-regulation of 23 genes. Real-time reverse transcriptase-polymerase chain reaction (RT-PCR) of selected, differentially expressed genes confirmed the microarray data. Many of these up- and down-regulated genes were related to cellular proliferation, including seven up-regulated genes encoding proliferation inhibitors and three down-regulated genes encoding proliferation promoters, strongly suggesting that T. cruzi infection inhibits host cell proliferation, which may allow more time for T. cruzi to replicate and produce its intracellular nests. These findings provide new insight into the molecular mechanisms by which intracellular T. cruzi infection influences the host cell, leading to pathogenicity.

Description
The character of the earliest cardiac precursor cells remains largely unknown. To elucidate this further, we constructed single cell cDNAs from the mouse embryonic cardiac precurcsor cells of the early allantoic bud stage and the early headfold stage, and subjected them to deep sequencing. Overall design: The most anterior part of the embryos where cardiac precursor cells exist was digested by trypsin to separate into single cells. After a cell was transferred into a reaction tube, single cell cDNAs were constructed as PCR amplicons. cDNAs of cardiac precursor cells were identified by PCR of marker genes.

Description
DNA methylation plays critical roles in the nervous system and has been traditionally considered to be restricted to CpG dinucleotides in metazoan genomes. Here we show that the single-base resolution neuronal DNA methylome from the adult mouse dentate gyrus consists of both CpG (~75%) and CpH (~25%) methylation (H = A/C/T). Neuronal CpH methylation is conserved in human brains, enriched in low CpG-density regions, depleted at protein-DNA interaction sites, and anti-correlated with gene expression. Functionally, both mCpGs and mCpHs can repress transcription in vitro and are recognized by MeCP2 in vivo. Unlike most CpG methylation, CpH methylation is established de novo during neuronal maturation and requires DNMT3A for active maintenance in post-mitotic neurons. These characteristics of CpH methylation suggest a significantly expanded proportion of the neuronal genome under cytosine methylation regulation and provide a new framework for understanding the roles of this key epigenetic modification in neuronal identity, maturation, plasticity and neurological disorders. Overall design: Three biological replicates (dentate gyrus samples from C57Black6 mice) were analyzed by mRNA-seq
