Description
Protocadherin 12 (Pcdh12) is a transmembrane adhesive protein with homophilic adhesive properties and expressed in endothelial cells, the glycogen trophoblast cells of the placenta, and the mesangial cells of kidney glomeruli. Pcdh12-deficient mice are alive although they show alterations in placenta development.

Description
Bariatric surgery is the most effective therapy of severe human obesity. It is associated with improvements in metabolic and non metabolic co-morbidities which are thought to be mediated by a decrease of adipose tissue inflammation. However, the molecular mechanisms behind these beneficial effects are poorly understood. We analyzed expression profiles in subcutaneous adipose tissue from 22 obese women before and 3 months after surgery using the RNA-seq technology. Of 15,972 detected genes, 1214 were differentially expressed after surgery. Upregulated genes were mostly involved in the basal cellular machinery. Downregulated genes were enriched in metabolic functions of adipose tissue. At baseline, we identified 26 modules of coexpressed genes. The four most stable modules reflected the innate and adaptive immune responses of adipose tissue, including a general signature of innate immune cells, an adaptive immune response elicited by T lymphocytes, a neutrophil-mediated inflammatory signature and an interferon-signaling pathway, respectively. After surgery, a few crucial molecules involved in chemotaxis and activation of immune cells were disconnected from their respective networks. These molecules may represent therapeutic targets against adipose inflammation. Overall design: mRNA sequencing of subcutaneous adipose tissue (SAT) samples from 22 obese women before and 3 months after bariatric surgery

Description
Molecular mechanisms that are responsible for the development of human skin epithelial cells are not completely understood so far. As a consequence, the efficiency to establish a pure skin epithelial cell population from human induced pluripotent stem cells (hiPSC) remains poor. Using an approach including RNA interference and high-throughput imaging of early epithelial cells, we could identify candidate kinases which are involved in skin epithelial differentiation. Among them, we found HIPK4 to be an important inhibitor of this process. Indeed, its silencing increased the amount of generated skin epithelial precursors, increased the amount of generated keratinocytes and improved growth and differentiation of organotypic cultures, allowing for the formation of a denser basal layer and stratification with the expression of several keratins. Our data bring substantial input in the regulation of human skin epithelial differentiation and for improving differentiation protocols from pluripotent stem cells.

Description
Three different progenitor cell subsets in subcutaneous and visceral adipose tissues derived from 5 obese patients were subjected to AmpliSeq transcriptome profiling. Transcriptomic profiles were analyzed to compare progenitor cell subsets and the impact of subcutaneous and visceral adipose tissue location. Overall design: Transcriptomic profiling of 3 different progenitor cell types in subcutaneous and visceral adipose tissues derived from 5 obese patients (3X2X5=30 samples).

Description
The size and scope of microarray experiments continue to increase. However, datasets generated on different platforms or at different centres contain biases. Improved techniques are needed to remove platform- and batch-specific biases. One experimental control is the replicate hybridization of a subset of samples at each site or on each platform to learn the relationship between the two platforms. To date, no algorithm exists to specifically use this type of control. LTR is a linear-modelling-based algorithm that learns the relationship between different microarray batches from replicate hybridizations. LTR was tested on a new benchmark dataset of 20 samples hybridized to different Affymetrix microarray platforms. Before LTR, the two platforms were significantly different; application of LTR removed this bias. LTR was tested with six separate data pre-processing algorithms, and its effectiveness was independent of the pre-processing algorithm. Sample-size experiments indicate that just three replicate hybridizations can significantly reduce bias. An R library implementing LTR is available.

Description
To identify the CD4+ T cell cytokines responsible for the proliferation of the Lin-IEL lines CD4+ T cell clone L10, which recognises DQ2-glia-1, one of the immunodominant T cell epitopes in celiac disease, was stimulated for 3 hours in IMDM with plate-bound CD3/CD28-specific (2.5 g/ml each) or control antibodies coated onto 6-well non-tissue culture treated plates. Three independent biological replicates were performed, each time including 6 million Ficoll-purified live cells per condition. RNA was purified from these cells using the RNAeasy mini kit (Qiagen, Venlo, the Netherlands). cDNA was amplified using the Applause WT-Amp system (NuGEN technologies, Bemmel, the Netherlands) and biotin-labelled with the Encore Biotin Module (NuGEN). Human Gene 1.0 ST arrays (Affymetrix, High Wycombe, UK) were employed to quantify global gene expression.
