- Illumina human-6 v2.0 expression beadchip
Description
Analysis of effect of long-term cryopreservation on peripheral blood mononuclear cells at gene expression level. The hypothesis tested in the present study was that long-term cryopreservation has an influence on the transcriptome profile of peripheral blood mononuclear cells. Results indicated remarkable changes in expression patterns upon cryopreservation of PBMCs, with decreasing signal intensities over time.

Description
Analysis of cryopreservation effects on peripheral blood mononuclear cells at gene expression level. The hypothesis tested in the present study was that cryopreservation has an influence on the transcriptome profile of peripheral blood mononuclear cells. Results indicated remarkable changes in expression patterns upon cryopreservation of PBMCs, with a strong loss of signal intensities to background levels for several transcripts.

Description
Analysis of long-term freezing on the stability of transcriptome profiles in PAXgene stabilized whole blood samples. In the present study it was tested if long-term freezing of PAXgene RNA tubes (up to one year) has an influence on the transcriptome profile of peripheral whole blood samples. Results indicated that gene expression profiles of whole blood samples stabilized with PAXgene RNA tubes remain stable for at least 1 year.

Illumina HiSeq 2000
Description
Host-microbe associations underlie many key processes of host development, immunity, and life history. Yet, none of the current research on the central model species Caenorhabditis elegans considers the worm's natural microbiome. Instead, almost all laboratories exclusively use the canonical strain N2 and derived mutants, maintained through routine bleach sterilization in monoxenic cultures with an E. coli strain as food. Here, we characterize for the first time the native microbiome of C. elegans and assess its influence on nematode life history characteristics via transcriptomics. Overall design: mRNA profiles of wild type (WT) C.elegans fed to either Ochrobactrum strain MYb65, MYb71, mixture of MYb65 and MYb71 or standard lab food E. coli OP50 at different life stages (from L2 to adults) were generated by deep sequencing, in triplicate, using Illumina HiSeq2000.

Description
We previously demonstrated by genomic and bioinformatical approaches that human macrophage (MF) activation is best described by a spectrum model (Xue et al, Immunity, 2014). MF integrate exogenous input signals on transcriptional level in a unique fashion to generate specific functional programs, enabling the plasticity in disease-related pathophysiologies. Such versatile responsiveness requires fast changes of transcription mediated by transcriptional regulators (TRs) or epigenomic changes. To better understand the principles of this regulation during human MF activation, we assessed histone modifications including H3K4me1, H3K4me3, H3K27me3, and H3K27Ac by ChIP-sequencing allowing us to characterize the functional state of promoters (active, poised, repressed) and enhancers (active, inactive, intermediate). Using transcriptome data from our MF spectrum model, we generated a co-regulation network of all TRs. Next, we overlaid epigenomic information and transcriptional changes of major TRs over time onto the TR network. We observed that input signals like IFN? or TNFa induce a specific network of TRs that are transcriptionally regulated themselves, the combination of regulated TRs changes over time with a boost of transcriptional regulation of dozens of TRs 4 to 12 hrs post input signal exposure, almost all TRs within the network show active promoters, even if the TR itself is not expressed, and similar results are obtained for enhancers with open or at least intermediated states. These findings strongly suggest that in MF, the TR-defined cellular ‘switch panel’ is always accessible thereby allowing MF to quickly respond to the diverse input signal repertoire from the environment. Overall design: Epigenetic analysis of promoter and enhancer sites in primary human macrophage subtypes and correlation to RNA-seq expression data

Description
The protease activity of the paracaspase MALT1 plays an important role in antigen receptor-mediated lymphocyte activation by controlling the activity of the transcription factor NF-kB and is thus essential for the expression of inflammatory target genes.

Description
Human pluripotent stem cells (hPSC) exposed to BMP4 (B) and inhibitors of ACTIVIN signaling (A83-01; A) and FGF2 (PD173074; P) in absence of FGF2 (BAP conditions) differentiate into colonies primarily comprised of trophoblast. In an attempt to isolate trophoblast stem cells, colonies of hESC were exposed to BAP for 24 h at which time they had begun to transition into a CDX2-positive state. Cultures were then dissociated into single cells by trypsin and grown on a gelatin substratum. Under these conditions, organized CDX2+/KRT7- colonies began to emerge within a few days. The self-renewing cell lines were not TBSC, but met standard criteria for pluripotency. They were named H1BP cells. They differed from the progenitor hPSC in morphology, ability to be clonally propagated from single cells onto gelatin, requirements for FGF2, and transcriptome profile.
Publication Title
Heightened potency of human pluripotent stem cell lines created by transient BMP4 exposure.
