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
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))

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
Dysfunction of the retinal pigmented epithelium (RPE) results in degeneration of photoreceptors and vision loss and is correlated with common blinding disorders in humans. Although many protein-coding genes are known to be expressed in RPEs and important for their development and maintenance, virtually nothing is known about the in vivo roles of non-protein coding transcripts in RPEs. The expression patterns of microRNAs (miRNAs) have been analyzed in a variety of ocular tissues, and few were implicated to play role in RPE based on studies in cell lines. Herein, through RPE specific conditional mutagenesis of Dicer1 or DGCR8, the importance of miRNA for RPE differentiation was uncovered. Interestingly, miRNAs were found to be dispensable for maintaining the RPE fate and survival, and yet they are essential for acquisition of important RPE properties such as the expression of genes involved in the visual cycle pathway, pigmentation and cell adhesion. Importantly miRNAs of the RPE were found to be required for maturation of the adjacent photoreceptors, specifically for the morphogenesis of the outer segments. The profiles of miRNA and mRNA altered in the Dicer1 deficient RPE point to a key role of miR-204 in regulation of RPE differentiation program in vivo and uncovers the importance of additional novel RPE miRNAs. The study exposes the combined regulatory activity of miRNAs of the RPE, which is required for RPE differentiation and for the development of the adjacent neuroretina.

Description
Circulating tumor cells (CTCs) play a fundamental role in cancer progression. However, in mice, limited blood volume and the rarity of CTCs in the bloodstream preclude longitudinal, in-depth studies of these cells using existing liquid biopsy techniques. Here, we present an optofluidic system that continuously collects fluorescently-labeled CTCs from a genetically-engineered mouse model for several hours per day over multiple days or weeks. The system is based on a microfluidic cell-sorting chip connected serially to an un-anesthetized mouse via an implanted arteriovenous shunt. Pneumatically-controlled microfluidic valves capture CTCs as they flow through the device and CTC-depleted blood is returned back to the mouse via the shunt. To demonstrate the utility of our system, we profile CTCs isolated longitudinally from animals over a four-day treatment with the BET inhibitor JQ1 using single-cell RNA-Seq (scRNA-Seq) and show that our approach eliminates potential biases driven by inter-mouse heterogeneity that can occur when CTCs are collected across different mice. The CTC isolation and sorting technology presented here provides a research tool to help reveal details of how CTCs change over time, allowing studies to credential changes in CTCs as biomarkers of drug response and facilitating future studies to understand the role of CTCs in metastasis.
