Description
In this study, murine primary aortic smooth muscle cells (SMCs) were transcriptionally profiled at baseline, after 3 d of cholesterol loading, and after 3 d of subsequent cholesterol unloading with HDL treatment, to identify vascular SMC genes that are transcripionally dysregulated in response to cholesterol loading and/or unloading.
Publication Title
Cholesterol loading reprograms the microRNA-143/145-myocardin axis to convert aortic smooth muscle cells to a dysfunctional macrophage-like phenotype.

Description
Huntington neurodegenerative disease (HD) is associated with extensive down-regulation of neuronal genes. We show preferential down-regulation of super-enhancer-regulated neuronal function genes in the striatum of HD mice. Striatal super-enhancers display extensive H3K27 acetylation within gene bodies and drive transcription characterized by low levels of paused RNAPII. Down-regulation of gene expression is associated with diminished H3K27 acetylation and RNAPII recruitment. Striatal super-enhancers are enriched in binding motifs for Gata transcription factors, such as Gata2 regulating striatal identity genes. Thus, enhancer topography and transcription dynamics are major parameters determining the propensity of a gene to be deregulated in a neurodegenerative disease. Overall design: RNA profiles in Striatum of WT and R6/1 mice by deep sequencing using Illumina HiSeq 2000.

Description
In order to gain insight into the molecular pathogenesis of collagen VI defects we have performed gene expression microarray analysis of dermal fibroblasts. We have compared the transcriptome of fibroblasts, treated or untreated with ascorbic acid, from UCMD patients (n = 6) and aged-matched healthy children (n = 5).

Description
Red blood cells (RBCs) mature within a specialized niche (the erythroblastic island (EI)), which consists of a central macrophage surrounded by differentiating erythroblasts. Human Induced Pluripotent Stem Cell derived macrophages (iPSC-DMs) enhance proliferation and terminal maturation of Umbilical Cord Blood (UCB) CD34+ derived erythroid cells and iPSC derived erythroid cells. These effects are further increased when an inducible KLF1-ERT2 fusion protein is activated in iPSC-DMs. To assess the mechanism of action, we sought to compare the transcriptome of iPSC-DMs with and without KLF1 activation. For this, we used an inducible IPSC line (iKLF1.2) in which upon tamoxifen addition, the KLF1 transcription factor is translocated to nucleus and consequently KLF1 downstream targets are expressed. The identification and characterisation of could identify factors involved in erythroid maturation and thus helpful to improve current protocols to manufacture RBCs in vitro. Overall design: iKLF1.2 iPSCs were differentiated to macrophages and then split into 2 groups, one was treated with tamoxifen for the last 4 days of culture to activate KLF1. The other group was not treated with tamoxifen. Four biologically independent differentiation experiments were carried out and so 8 samples were generated: 4 samples of untreated iKLF1.2 iPSCs-derived macrophages and 4 samples of tamoxifen treated iKLF1.2 iPSC-derived macrophages. Total RNA was extracted from each sample and RNA integrity was of a high enough quality for library preparation, as all RIN values were above 9 for every sample.

Description
We have previously reported that elevated fibroblast growth factor-2 (FGF-2) expression is associated with tumor recurrence and reduced survival after surgical resection of esophageal cancer, and that these risks are reduced in tumors co-expressing an endogenous antisense (FGF-AS) RNA. In the present study we examined the role of the endogenous FGF-AS transcript in the regulation of FGF-2 expression in the human lung adenocarcinoma cell line, Seg-1. FGF-2 and FGF-AS were temporally and spatially co-localized in the cytoplasm of individual cells, and knock-down of either FGF-2 or FGF-AS by target specific siRNAs resulted in dose-dependent up-regulation of the complementary transcript and its encoded protein product. Using a luciferase reporter system we show that these effects are mediated by interaction of the endogenous antisense RNA with the 3UTR of the FGF-2 mRNA. Deletion mapping identified a 392 nt sequence in the 5823 nucleotide FGF-2 untranslated tail which is targeted by FGF-AS. siRNA-mediated knockdown of either FGF-AS or FGF-2 significantly increased the stability of the complementary partner mRNA, demonstrating that these mRNAs are mutually regulatory. Knockdown of FGF-AS also resulted in reduced expression of argonaute-2 (AGO-2) and a number of other elements of the endogenous microRNA/RNAi pathways. Conversely, siRNA-mediated knockdown of AGO-2 significantly increased the stability of the FGF-2 mRNA transcript, and the steady-state levels of both FGF-2 mRNA and protein, suggesting a role for AGO-2 in the regulation of FGF-2 expression.

Description
To determine whether immortalized cells derived from the rat SCN (SCN 2.2) retain intrinsic rhythm-generating properties characteristic of the SCN, oscillatory properties of the SCN2.2 transcriptome were analyzed and compared to those found in the rat SCN in vivo using rat U34A Affymetrix GeneChips. SCN2.2 cells were expanded in 6-well plates. At 6-hour interval across 2 circadian cycles, cells from single 6-well plates were harvested and pooled for total RNA extraction.
