Description
To provide further insight about the effects of prolonged Ezh2 inhibition in glioblastoma using preclinical mouse models and doxycycline-inducible shRNAs that mimic the effects of a selective EZH2 inhibitor. We demonstrate that prolonged Ezh2-depletion causes a robust switch in cell fate, including significantly enhanced proliferation and DNA damage repair and activation of part of the pluripotency network, resulting in altered tumor cell identity and tumor progression. Overall design: SVZ derived neural stem cells (NSCs) were isolated from 7 days old p53;Ink4a/Arf;Krasv12;LucR compound conditional mice and cultured in NSC specific serum-free medium supplemented with 20ng/ml of both EGF and bFGF (R&D systems). NSCs were grown adhesion-free for the first passages to eliminate non-sphere-forming cells. Next, cells were grown adherent on poly-L-Ornithine and Laminin plates and three times infected with lentiviral CMV-Cre. These floxed, tumorigenic cells are further referred as glioma initiating cells (GICs). Next, GICs were infected with a tet-inducible, doxycycline-responsive short hairpin construct (FH1-tUTG-shEzh2). After FACS sorting for GFP, GICs were injected intracranial in NOD-SCID mice and treated with or without doxycycline in the drinking water

Illumina HumanWG-6 v3.0 expression beadchip
Description
One major class of anti-cancer drugs targets topoisomerase II to induce DNA double-strand breaks and cell death of fast growing cells. In vitro experiments showed that doxorubicin can induce histone eviction as well as DNA damage, while etoposide can only induce DNA damage. Here, we compare the transcription responses of different tissues to doxorubicin or etoposide treatment in vivo.

Description
We describe Hi-C, a method that probes the three-dimensional architecture of whole genomes by coupling proximity-based ligation with massively parallel sequencing. We constructed spatial proximity maps of the human genome with Hi-C at a resolution of 1Mb. These maps confirm the presence of chromosome territories and the spatial proximity of small, gene-rich chromosomes. We identified an additional level of genome organization that is characterized by the spatial segregation of open and closed chromatin to form two genome-wide compartments. At the megabase scale, the chromatin conformation is consistent with a fractal globule, a knot-free conformation that enables maximally dense packing while preserving the ability to easily fold and unfold any genomic locus. The fractal globule is distinct from the more commonly used globular equilibrium model. Our results demonstrate the power of Hi-C to map the dynamic conformations of whole genomes.

Description
The ability to cope with infection by a parasite is one of the major challenges for any host species and is a major driver of evolution. Parasite pressure differs between habitats. It is thought to be higher in tropical regions compared to temporal ones. We infected Drosophila melanogaster from two tropical (Malaysia and Zimbabwe) and two temperate populations (the Netherlands and North Carolina) with the generalist entomopathogenic fungus Beauveria bassiana to examine if adaptation to local parasite pressures led to differences in resistance. Contrary to previous findings we observed increased survival in temperate populations. This, however, is not due to increased resistance to infection per se, but rather the consequence of a higher general vigor of the temperate populations. We also assessed transcriptional response to infection within these flies eight and 24 hours after infection. Only few genes were induced at the earlier time point, most of which are involved in detoxification. In contrast, we identified more than 4,000 genes that changed their expression state after 24 hours. This response was generally conserved over all populations with only few genes being uniquely regulated in the temperate populations. We furthermore found that the American population was transcriptionally highly diverged from all other populations concerning basal levels of gene expression. This was particularly true for stress and immune response genes, which might be the genetic basis for their elevated vigor. Overall design: mRNA profiles of whole Drosophila melanogaster adult males from an African, American, Asian and European population after infection with Beauveria bassiana. Samples include uninfected controls, 8h after infection and 24h after infection. 3 biological replicates each (2 in the case of American controls).
