Affymetrix Murine Genome U74A Version 2 Array (mgu74av2)
Description
We sought to find molecular signatures of the SGZ cell types, and to characterize the molecular pathways and transcription factor cascades that define the neurogenic niche. We used laser capture microdissection and DNA microarrays to profile gene expression in the inner (SGZ) and outer portions of the dentate gyrus (DG). Since the vast majority of the cells in the DG are mature granule cells, we compared the expression of the inner and outer portions to reveal molecular markers for the less numerous populations of the SGZ.

- Affymetrix Rhesus Macaque Genome Array (rhesus)
Description
Genome-wide transcriptional profiling allows characterization of the molecular underpinnings of neocortical organization, including cortical areal specialization, laminar cell type diversity and functional anatomy. Microarray analysis of individual cortical layers across sensorimotor and association cortices in rhesus macaque demonstrated robust and specific laminar and areal molecular signatures driven by differential expression of genes associated with specialized neuronal function. Gene expression corresponding with laminar architecture was generally similar across cortical areas, although genes with robust areal patterning were often highly laminar as well, and these patterns were more highly conserved between macaque and human as compared to mouse. Layer 4 of primate primary visual cortex displayed a distinct molecular signature compared to other cortical regions, a specialization not observed in mouse. Overall, transcriptome-based relationships were strongest between proximal layers in a cortical area, and between neighboring areas along the rostrocaudal axis, reflecting in vivo cortical spatial topography and therefore a developmental imprint.

Description
Medulloblastoma is the most common form of malignant paediatric brain tumour and is the leading cause of childhood cancer related mortality. The four molecular subgroups of medulloblastoma that have been identified WNT, SHH, Group 3 and Group 4 - have molecular and topographical characteristics suggestive of different cells of origin. Definitive identification of the cell(s) of origin of the medulloblastoma subgroups, particularly the poorer prognosis Group 3 and Group 4 medulloblastoma, is critical to understand the pathogenesis of the disease, and ultimately for the development of more effective treatment options.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
KMS-11 and KMS-34 cells were exposed to stepwise increasing concentrations of carfilzomib over a period of 18 weeks: cells adapted to growth in 4 nM carfilzomib by 4 weeks, in 6 nM in another 6 weeks and in 12 nM after a further 8 weeks. The resulting cell cultures, denoted KMS-11/Cfz and KMS-34/Cfz, respectively, retained resistance to carfilzomib even when tested after removal of selective pressure for approximately 8 weeks.

Description
The goal of this work was to identify all estrogen receptor beta target genes using RNA sequencing in MDA-MB-468 triple negative breast cancer cells engineered with inducible expression of full length estrogen receptor beta. Overall design: MDA-MB-468 breast cancer cells with inducible ERb expression (MDA-468-ERb cells) were treated in triplicate with vehicle (control, no ERb) or doxycycline (plus ERb) for 48 hr prior to treatment with 0.1% DMSO vehicle or 10 nM 17b-estradiol for 4 hr.

Description
We examined transcriptome-wide effects of pertrurbation in KLF10 function (siKLF10) on TGFß-regulated genes and EMT in two different cells lines: A549 and Panc1. Overall design: We performed mRNA sequencing from A549 and Panc1 cells following following TGFß treatment and KLF10 knockdown. The mRNA-Seq includes following conditions: siControl, siKLF10, TGFß, siKLF10+TGFß (A549 and Panc1 cells). mRNA-sequencing was performed in duplicates for A549 and triplicates for Panc1 cells.

Description
Purpose: ATG41 is involved both in autophagy and zinc-deficient growth. The goal of this study is to compare transcriptomic profiles of wild-type and atg41? strains to discover autophagy-independent molecular phenotypes for the mutant. The atg1? mutant is a control for autophagy activity. Methods: Wild-type and mutant yeast were grown to mid-log phase in replete medium and shifted to zinc-deficient medium for 8 hours, after which, cells were harvested for RNA sequencing to detect differential gene expression. Results: Gene expression data for virtually every gene (~6,000) was obtained with ~12,000,000 reads per sample. Differential gene expression analysis showed that several hundred genes were differentially experessed in the atg41? mutant (greater than 2-fold) at an FDR of 0.5. Conclusions: Most strikingly, we found that the atg41? mutant transcriptome shows signs that sulfur metabolism is distrupted during zinc-deficinet growth. Expression of Met4 gene targets is increased. Overall design: mRNA from wild-type, atg1?, and atg41? yeast strains was prepared from zinc-deficient cultures in quadruplicate and sequenced. Single-end, 100bp sequencing was performed, using v4 SBS chemistry on an Illumina HiSeq2500 sequencer.

Description
We examined context specific function of BRD4 in promoting lineage specific gene expression and show that BRD4 is essential for osteoblast differentiation. Overall design: We performed mRNA sequencing from hFOB cells (undifferentiated and differentiated for 5 days into osteoblastic lineage) following BRD4 inhibition by JQ1 or siRNA mediated depletion. The mRNA-Seq includes namely 7 conditions: undifferentiated hFOBs treated with DMSO or non-targeting control siRNA (siCNTR), differentiated hFOBs with DMSO or siCNTR treatments; differentiated hFOBs treated with JQ1 or two siRNAs against BRD4 (#3 & #4). The libraries were performed in triplicates.
