Illumina HiSeq 4000
Description
We reprogrammed fibroblasts from 5 HLHS patients and 2 controls into iPSCs and differentiated into cardiomyocytes. By comparison of HLHS and control groups we uncovered the developmental, structural and functional defects of HLHS cells. Through high through-put screening, the underlying molecular mechnisms of HLHS ontology was explored. Overall design: Cardiomyocyte mRNA profiles of normal control and HLHS samples were generated by deep sequencing, in duplicate, using Illumina HiSeq4000.

Description
Experiment: Expression profiling in breast cancer brain metastases (BC) compared to breast cancers (BC) and primary brain tumors (prBT). The objectives are to identify expression profiles that are specific to BCBM in order to identify new molecular biomarkers. The characterization of the BCBM samples included adjacent genetic techniques.

Description
Polycomb repressive complex-2 (PRC2) is a group of proteins that play important role during development and in cell differentiation. PRC2 is a histone-modifying complex that catalyses methylation of lysine 27 of histone H3 (H3K27me3) at differentiation genes leading to their transcriptional repression. JARID2 is a co-factor of PRC2 and is important for targeting PRC2 to chromatin as well as modulating its activity. Here, we show that in many human cells, including human epidermal keratinocytes, JARID2 predominantly exists as a novel low molecular weight form, which lacks the N-terminal PRC2-interacting domain (?N-JARID2). We show that ?N-JARID2 is a cleaved product of full-length JARID2 spanning the C-terminal conserved region consisting of jumonji domains. JARID2 knockout in keratinocytes results in up-regulation of cell cycle genes and repression of many epidermal differentiation genes. Surprisingly, repression of epidermal differentiation genes in JARID2-null keratinocytes can be relieved by expression of ?N-JARID2 suggesting that this form promotes activation of these genes and has opposing function to that of PRC2 in regulation of differentiation. We propose that a switch from expression of full-length JARID2 to ?N-JARID2 is important for the up-regulation of genes during differentiation. Overall design: RNA-seq analysis of Wildtype and JARID2-null keratinocytes (HaCaTs) on day 0 and day 3 of calcium induced differentiation.

A novel form of JARID2 is required for differentiation in lineage-committed cells.

Description
Cumulus cells are biologically distinct from other follicular cells and perform specialized roles, transmitting signals within the ovary and supporting oocyte maturation during follicular development. The bi-directional communication between the oocyte and the surrounding cumulus cells is crucial for the acquisition of oocyte competence. Using Illumina/deep-sequencing technology, we dissected the small RNAome of pooled human mature MII oocytes and cumulus cells. Overall design: Cumulus cells and MII mature oocytes small RNA profiles were generated by deep-sequencing, using Illumina 1G sequencer

Description
We examined the effect pg IGF1 actibation on cellular contractility and migration in SSC osteoblast cells. Based on microarray levels of IGF1 expression, we selected fifteen cases and nine controls spanning from the highest IGF1 expression to the lowest in cases and controls. Subsequently, the pattern of IGF1 expressions in these cells was assessed using high throughput RNA sequencing. Overall design: RNA-seq based gene expression profiling of fifteen SSC osteoblasts and nine control osteoblasts.
Publication Title
Activation of the IGF1 pathway mediates changes in cellular contractility and motility in single-suture craniosynostosis.

Description
We recently reported that carbon monoxide (CO) has bactericidal activity. To understand its mode of action we analysed the gene expression changes occurring when Escherichia coli, grown aerobically and anaerobically, is treated with the carbon monoxide releasing molecule, CORM-2. The E. coli microarray analysis shows that E. coli CORM-2 response is multifaceted with a high number of differentially regulated genes spread through several functional categories, namely genes involved in inorganic ion transport and metabolism, regulators, and genes implicated in posttranslational modification, such as chaperones. CORM-2 has higher impact in E. coli cells grown anaerobically, as judged by the existence of repressed genes belonging to eight functional classes which are absent in aerobically CORM-2 treated cells. In spite of the relatively stable nature of the CO molecule, our results show that CO is able to trigger a significant alteration in the transcriptome of E. coli which necessarily has effects in several key metabolic pathways.

Description
To assess the effect of different forms of TL1A within different organs of the mouse we generated 2 different transgenic mouse lines where TL1A was expressed under the control of the CD2 promoter. 2 forms of TL1A was used. Either WT TL1A, which led to over expression of both membrane bound and soluble forms of TL1A (Refered to as Mem+Sol) or TL1A Delta 69-93 which only overexpressed membrane restricted TL1A (Refered to as Mem). Lungs and terminal ileums were taken from Either Mem, Mem+sol or WT litermate control mice at 12 weeks of age and the transcriptome assessed using RNAseq Through this we demonstrated enrichment of different transcripts and pathways both dependent on and independent of the form of TL1A and the site of action. This study is also the first to use RNASeq to assess the resualt of overexpression of TL1A within the mouse. Overall design: Poly-A purified mRNA profiles from the Ileum and Lung of Mem, Mem+Sol and WT mice generated using Illumina based RNASeq
