  • The dimerization and binding of DNA by BldD is affected by its interaction with cyclic di-GMP. The D116A mutant of BldD is partially impaired in its biding of cyclic di-GMP. ChIP-Seq was carried out to determine the difference in the degree of DNA binding by the wild type and D116A mutated BldD in Streptomyces venezuelae.

  • BldC is a transcriptional regulator essential for morphological development Streptomyces venezuelae. Although bldC deletion strain is unable to produce aerial hyphae, electron microscopy reveals that almost all of the colony biomass is in the form of spores rather than undifferentiated vegetative hyphae. This ChIP-chip experiment was carried out to determine the binding sites, and thence the regulon, of BldC in Streptomyces venezuelae. Cy3(IP):Cy5(Total) signal ratios in the wild type were compared to those in a bldC knockout strain.

  • Human intestinal epithelial organoids (IEO) culture models are rapidly emerging as novel experimental tools to investigate fundamental aspects of intestinal epithelial (patho)physiology. Cellular source and culture protocols vary between different IEO models and reliable markers for their characterization/validation are currently limited. DNA methylation has been demonstrated to play a key role in regulating gene expression and cellular function. This epigenetic mark is comparably stable and has been shown to reflect cellular identity such as tissue origin, developmental stage and age. Our genome wide DNA methylation datasets of purified human epithelium represent a unique resource, which can be used by other researchers to validate their model systems We provide the following datasets of genome-wide DNA methylation profiling by Infinium HumanMethylation450 BeadChip: Purified intestinal epithelial cells (EpCAM+) from paediatric ileum and colon, Non-epithelial mucosal cells (EpCAM-), Whole colonic mucosal biopsies, Intestinal organoid cultures from paediatric ileum and colon, Purified intestinal epithelial cells (EpCAM+) from foetal small intestine and foetal large intestine, Intestinal organoid cultures from foetal small intestine and foetal large intestine, Intestinal organoid cultures derived from induced pluripotent stem cells. Note: Some samples in this data set were previously submitted to ArrayExpress under accession number E-MTAB-3709. They're clearly marked in the “Description” field in sample annotations. Information about batch effect during sample handling is included in the experimental variable “block”. Batch effect is not massive but present, so it is recommended that batch correction is carried out in data analysis. Complementary RNA-seq data on the purified cells and organoids can be found in ArrayExpress at E-MTAB-5015 ( https://www.ebi.ac.uk/arrayexpress/experiments/E-MTAB-5015/ ).

  • Ewings Sarcoma (ES) belongs to the group of bone cancers defined by the existence of a certain EWS-ETS fusion gene. In this study we use the model cell line CADO-ES1 (EWSR1-ERG fusion gene) to characterize the tumor biology of a versatile ES side-population (SP). We aim to compare SP- and non-SP-cells to identify specific characteristics of the SP which points towards a tumor driving functionality of the SP. Due to some stem cell like properties of the SP fraction a comparison to MSCs and normal fibroblasts as a control are also performed.

  • Objective was to identify urine cell-free microRNAs enabling early non-invasive detection of bladder cancer. Total RNA enriched for fraction of short RNAs was isolated using Urine microRNA purification kit (Norgen corp.). miRNA profiles were determined using the Affymetrix GeneChip miRNA 3.0 array and analyzed to identify differentially deregulated miRNA in bladder cancer patients compared with helathy controls.

  • Cardiomyocytes derived from human pluripotent stem cells were exposed to the cardiotoxic drug Doxorubicin in order to assess the utility of this cell system as a model for drug-induced cardiotoxicity. Cells are exposed to different concentrations of doxorubicin for up to 48 hours followed by a 12 days recovery period.

  • Analysis of gene expression patterns of B-1 cells from C57BL6 wild type mice versus B-1 cells fromIL-10 Knockout mice. This study will help in the identification of factors in B-1 cells involved in changing of metastatic behavior of B16 melanoma after contacting with B-1 lymphocytes.
