Arabidopsis Gene 1.1 ST Array (aragene11st)
Description
SuperSeries contain expression data from the nuclei of cell types involved in patterning events, with focus on root apical stem cell formation, at 16-cell stage, early globular stage and late globular stage in the early Arabidopsis embryo (atlas). Expression data comparing nuclear and cellular RNA isolated from whole 16-cell stage Arabidopsis embryos is also included.

Description
The establishement of the first plant tissues occurs during embryo development. Indeed, cell types that will form the Arabidopsis root stem cell niche are first specified during 16-cell (16C), early globular (EG) and late globular (LG) stage of embryonic development. While some regulatory factors are known, we do not yet understand the genetic networks underlying the specification of these cell types. One main reason for this is the difficulties in adapting genome-wide approaches to the cellular level. Here, we have adapted such an approach (INTACT) to generate microarray-based cell type-specific transcriptomic profiles at 16C to LG stage for use in determining the role of the transcriptome in cell specification and differentiation during root stem cell niche formation.

Illumina HiSeq 2000
Description
We infected Mouse Embryonic Fibroblast and cultured them in anchorage independent conditions to study tranformation induced by the bacterium. We cultured these transformed cells multiple rounds in the presence of Ciprofloxacin to remove intracellular Salmonella after transformation occured. By doing RNA sequencing we indentified genes of which expression was altered upon infection. This helps us to understand how Salmonella alters the host cell, resulting in transformation Overall design: We Cultered two biological duplicates of infected MEF cells, which we compared to a non transformed MEF control sample

Description
Using a chromatin regulator-focused shRNA library, we found that suppression of sex determining region Y-box 10 (SOX10) in melanoma causes resistance to BRAF and MEK inhibitors. To investigate how SOX10 loss leads to drug resistance, we performed transcriptome sequencing (RNAseq) of both parental A375 (Ctrl. PLKO) and A375-SOX10KD (shSOX10-1, shSOX10-2) cells. To ask directly whether SOX10 is involved indrug resistance in BRAF(V600E) melanoma patients, we isolated RNA from paired biopsies from melanoma patients (pre- and post- treatment) , that had gained BRAF or MEK inhibitor resistance . We performed RNAseq analysis to determine changes in transcriptome upon drug resistance. Overall design: Investigate genes regulated by SOX10 and differntial gene expression between pre- and post-treatment biopsies. We use short hairpin RNA to suppression SOX10 in A375 cells and cells were harvested with trizol reagent for RNA isolation. For paired biopsies (patient samples) we collected the first biopsy before the initiation of treatment and the second biopsy after drug resistance developed. RNA was isolated from FFPE samples and subjected for RNA sequencing.

Description
The discovery of the first histone demethylase in 2004 (LSD1/KDM1) opened new avenues for the understanding of how histone methylation impacts cellular functions. A great number of histone demethylases have been identified since, which are potentially linked to gene regulation as well as to stem cell self-renewal and differentiation. KDM6A/UTY and KDM6B/JMJD3 are both H3K27me3/2-specific histone demethylases, which are known to play a central role in regulation of posterior development, by regulating HOX gene expression. So far nothing is known about the role of histone lysine demethylases (KDMs) during early hematopoiesis. We are studying the role of KDM6A and KDM6B on self-renewal, global gene expression and on local and global chromatin states in embryonic stem cells (ESCs) and during differentiation. In order to completely abrogate KDM6 demethylase activity in ESCs we employed a specific inhibitor (GSK-J4, Kruidenier et al. 2012). Treatment of ESCs with GSK-J4 had no effect on viability and proliferation . However, ESC differentiation in the presence of GSK-J4 was completely abrogated. In conclusion we show that ESC differentiation is completely blockend in the absence of any H3K27 demethylase activity.
