Description
L-type voltage gated Ca channels play a critical role in E-C coupling in cardiac muscle. alpha1C is associated with beta auxiliary subunits (b1-b4), which regulate cardiac Ca channel gating properties. Here we report a preliminary exploratory study suggesting a novel role of beta4 subunit in heart. We observed that overexpression of beta4 subunit increases the expression of a wide variety of endogenous genes related to antiviral activity. This includes genes in the downstream signalling of RIG-1 pathway such as RIG-1, Irf7 and Ifitm3. The increase expression of these factors may have an antiviral protective role against infection. Overall design: Examination of an overall differential expression by the beta4 subunit

Description
Dramatic changes of gene expressions are known to occur in human endometrial stromal cells (ESC) during decidualization. The changes in gene expression are associated with changes of chromatin structure, which are regulated by epigenetic mechanisms such as histone modifications. Here, we investigated genome-wide changes in histone modifications and mRNA expressions associated with decidualization in human ESC using chromatin immunoprecipitation (ChIP) combined with next-generation sequencing. ESC were incubated with estradiol and medroxyprogesterone acetate for 14 days to induce decidualization. The ChIP-sequence data showed that induction of decidualization increased H3K27ac and H3K4me3 signals in many genomic regions but decreased in only a few regions. Most (80%) of the H3K27ac-increased regions and half of the H3K4me3-increased regions were located in the distal promoter regions (more than 3 kb upstream or downstream of the transcription start site). RNA-sequence showed that induction of decidualization up-regulated 881 genes, 223 of which had H3K27ac- or H3K4me3-increased regions in the proximal and distal promoter regions. Induction of decidualization increased the mRNA levels of these genes more than it increased the mRNA levels of genes without H3K27ac- or H3K4me3-increased regions. Pathway analysis revealed that up-regulated genes with the H3K27ac- or H3K4me3-increased regions were associated with insulin signaling. These results show that histone modification statuses genome-widely change in human ESC by induction of decidualization. The main changes of histone modifications are increases of H3K27ac and H3K4me3 in both the proximal and distal promoter regions, which are involved in the up-regulation of gene expression that occurs during decidualization. Overall design: mRNA profiles of human endometrial stromal cells with and without EP inductions for 2 individuals. (EP induction: induction with estradiol (10-8 M) and medroxyprogesterone acetate (10-6 M))

Profiles of genome-wide DNA methylation were investigated in leiomyomas and in myometrium with and without leiomyomas. Profiles of DNA methylation in the myometrium with and without leiomyomas were quite similar while those in leiomyomas were distinct.

Description
To address the role of INO80/SWR-type remodeling complexes, we deleted Ep400 at defined times of mouse oligodendrocyte development. Whereas oligodendrocyte precursors are specified and develop normally without Ep400, terminal differentiation is dramatically impaired resulting in hypomyelination. RNA-Seq studies were performed on cultured and FACS sorted control and Ep400-deficient mouse oligodendrocytes to analyze changes in gene expression. These revealed that genes associated with the myelination program and with response to DNA damage are altered in Ep400-deficient oligodendrocytes. Overall design: OPC mRNA profiles of 6-day old control (ctrl) and Ep400 cko mice were generated using the Illumina HiSeq 2500 platform.

Description
Epiblast stem cells (EpiSCs) were derived from the epiblast or the ectoderm (epi/ect) of pre-gastrula stage to late-bud stage mouse embryos. To identify if the EpiSCs retain any original stage specific characteristics or which developmental stage of epi/ect they most closely related to, we performed microarray analysis to compare the gene expression profile of multiple EpiSC lines with that of epi/ect of 7 different stages.

Description
When assembling a nephron during development a multipotent stem cell pool becomes restricted as differentiation ensues. A faulty differentiation arrest in this process leads to transformation and initiation of a Wilms'' tumor. Mapping these transitions with respective surface markers affords accessibility to specific cell subpopulations. NCAM1 and CD133 have been previously suggested to mark human renal progenitor populations. Herein, using cell sorting, RNA sequencing, in vitro studies with serum-free media and in vivo xenotransplantation we demonstrate a sequential map that links human kidney development and tumorigenesis; In nephrogenesis, NCAM1+CD133- marks SIX2+ multipotent renal stem cells transiting to NCAM1+CD133+ differentiating segment-specific SIX2- epithelial progenitors and NCAM1-CD133+ differentiated nephron cells. In tumorigenesis, NCAM1+CD133- marks SIX2+ blastema that includes the ALDH1+ WT cancer stem/initiating cells, while NCAM1+CD133+ and NCAM1-CD133+ specifying early and late epithelial differentiation, are severely restricted in tumor initiation capacity and tumor self-renewal. Thus, negative selection for CD133 is required for defining NCAM1+ nephron stem cells in normal and malignant nephrogenesis. Overall design: Human fetal kidney mRNA profiles of 3 cell populations (NCAM1+/CD133-, NCAM+/CD133+, NCAM-/CD133+) were generated by deep sequencing using Illumina HiSeq.
