Description
We report, for the first time, engineering of heteropolar cardiac tissues containing distinct atrial and ventricular ends, and demonstrate their spatially confined responses to serotonin and ranolazine. Uniquely, electrical conditioning for up to 8 months enabled modeling of polygenic left ventricular hypertrophy starting from patient cells. Overall design: hiPSC-CMs from 3 affected (Left Ventricular Hypertrophy [LVH]) and 3 non-affected donors were sequenced using ThermoFisher's whole transcriptome targeted AmpliSeq assay

Description
PUF proteins have become a leading scaffold for designing RNA-binding proteins to contact and control RNAs at will. We analyze the effects of that reengineering across the transcriptome in vivo for the first time. We show, by HITS-CLIP and PAR-CLIP, that S. cerevisiae Puf2p, a non-canonical PUF protein, binds more than 1000 mRNA targets. Puf2p binds multiple UAAU elements, unlike canonical PUF proteins. We also perform CLIP-seq on truncations of Puf2p, showing that its prion domain is dispensable for WT binding. We design a modified Puf2p to bind UAAG rather than UAAU, which allows us to align the protein with the binding site. In vivo, the redesigned protein binds UAAG sites. Its altered specificity redistributes the protein away from 3'UTRs, such that the protein tracks with its sites and binds throughout the mRNA. We use RNA-seq to determine that R1 SNE Puf2p represses a novel RNA network. Overall design: CLIP-seq was performed in BY4742 S. cerevisiae grown in log phase, and using 2 replicates of TAP-tagged proteins. RNA-seq was performed to determine the regulatory effect of WT or mutant Puf2p, using 4 replicates of the control (no Puf2p), 3 of WT Puf2p and 4 of R1 SNE Puf2p.

Description
This experiment was designed to look for in vitro IL-3 gene signature in donor blood at two different time points (6 and 24 hours). RNA from lysed whole blood cells was used for the sequencing. Overall design: Lysed whole blood from seven healthy donors was stimulated with recombinant human IL-3 for 6 hours, or 24 hours, prior to RNA extraction for next-generation sequencing on the Illumina HiSeq platform. Unstimulated samples were included as controls.

Affymetrix Zebrafish Genome Array (zebrafish)
Description
In addition to satisfying the metabolic demands of cells, mitochondrial metabolism helps regulate immune cell function. To date, such cell-intrinsic metabolic-immunologic cross-talk has only been described operating in cells of the immune system. Here we show that epidermal cells utilize fatty acid -oxidation to fuel their contribution to the immune response during cutaneous inflammation. By live imaging metabolic and immunological processes within intact zebrafish embryos during cutaneous inflammation, we uncover a mechanism where elevated -oxidation-fueled mitochondria-derived reactive oxygen species within epidermal cells helps guide matrix metalloproteinase-driven leukocyte recruitment. This mechanism requires the activity of a zebrafish homolog of the mammalian mitochondrial enzyme, Immunoresponsive gene 1. This study describes the first example of metabolic reprogramming operating within a non-immune cell type to help control its contribution to the immune response. Targeting of this metabolic-immunologic interface within keratinocytes may prove useful in treating inflammatory dermatoses.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Comparison of Mpl-/- mouse LSK cells, either treated with control (GFP) or Mpl lentivirus. Lineage negative bone marrow cells were isolated and transduced and transplanted into Mpl-/- recipient mice. After transplantation and follow up mice were sacrificed and LSK (lineage negative, Sca-1 positive, cKit positive) cells were isolated by FACS. RNA was isolated using RNeasy Micro Kit (Qiagen GmbH, Hilden, Germany) and RNA was amplified for microarray hybridization using the Nugen Ovation system (Nugen Technologies, AC Bemmel, Netherlands). The resulting material was hybridized to Affymetrix Mouse 430 2.0 arrays. RMA normalization and summarization was performed in R 2.10 using Bioconductor packages. The aim was to show the normalization of Mpl associated gene expression.

Description
The adult heart contains macrophages derived from both embryonic and adult bone-marrow derived precursors. Such population diversity raises the possibility that macrophages of distinct origins occupy differing biological roles or anatomical niches within the heart. Here, we provide evidence for the latter, showing that bone-marrow derived macrophages express the chemokine receptor Ccr2 and preferentially localise to the aortic root of the heart. This targeted migration occurs via a Ccr2-Ccl7 axis, whereby Ccl7-producing cardiac fibroblasts populating the aortic root, recruit Ccr2pos macrophages. Notably, the selective recruitment of Ccr2pos macrophages renders the aortic root sensitive to inflammatory disease. In a mouse model of Kawasaki Disease, acute inflammation drives a numerical increase in bone-marrow derived Ccr2pos macrophages, which accumulate at the aorta and trigger local inflammation at this site. We propose that cardiac fibroblasts recruit Ccr2pos macrophages to the aortic root, and that this process targets inflammatory disease to the heart's major vessels. Overall design: Mice were either naïve or challenged with a Candida albicans water-soluble complex (CAWS) to induce a mouse model of Kawasaki Disease. Cardiac macrophages were extracted from three independent pools of naive mice and three independent pools of CAWS challenged mice. Splenic monocytes were extracted from three independent pools of naive mice. In each case, cardiac macrophages were divided into three subpopulations (R1, R2 and R3) based on Ccr2 and MHC-II expression.

The purpose of this experiment was to assess the genes upregulated when pDCs were stimulated with TLR7 agonist imiquimod and TLR9 agonist CpG C. Overall design: pDCs were isolated from six healthy donors by FACS sorting, and were stimulated with CpG and imiquimod for 18 hours, after which RNA was extracted for next generation sequencing on the Illumina HiSeq platform. Unstimulated samples were included as controls.
