Description
The goal of this study is to characterize the genes that are specifically expressed in the shaft cells of olfactory sensory organ precursors, and regulate nanopore formation on cuticular sheath. To this end, pupal antennae of a wild type strain and two mutant strains (amos and neur>Nb) of Drosophila were subjected to RNA-seq analysis.

Description
Open chromatin is induced locally during the repair of DNA double strand breaks, when a cascade of protein recruitments and modifications is triggered. This "ATM cascade" includes components like the Mrn complex, ATM kinase, phosphorylated histon variant ?H2AX, MDC1, E3 ligases RNF 8 and RNF8, 53BP1, and Rif1. Recent investigations have shown that also the Mad2l2 protein is a downstream effector of the ATM cascade during DNA repair. It was first described as an accessory subunit during translesion DNA repair, and more recently as a key factor inhibiting the resection of DNA 5`ends, thus promoting non-homologous end joining, and repressing homologous recombination.Naive embryonic stem cells (ESCs) have a globally open chromatin. A preliminary study from this laboratory has demonstrated that ESCs require the presence of the Mad2l2 protein for the maintenance of their transcriptional and epigenetic profiles, and thus for the stability of pluripotency (Pirouz et al., Cell Cycle 14, 1596, 2015). The aim of the present study was to correlate Mad2l2 with the ATM cascade and the chromatin status in ESCs.

Description
Xenopus laevis embryos were injected with alpha-amanitin to inhibit RNA polymerase II activity. Embryos were allowed to develop up to stage 10.5 (early gastrula, control and alpha-amanitin injected embryos) and subsequently collected for RNA isolation. The transcriptome profiles of alpha-amanitin injected and control embryos were compared.

Description
Pediatric acute lymphoblastic leukemia (ALL) contains cytogenetically distinct subtypes that respond differently to cytotoxic drugs. Subtype classification can be also achieved through gene expression profiling. However, how to apply such classifiers to a single patient and correctly diagnose the disease subtype in an independent patient group has not been addressed. Furthermore, the underlying regulatory mechanisms responsible for the subtype-specific gene expression patterns are still largely unknown. Here, by combining three published microarray datasets (PMIDs: 12086872, 12730115, 17002788) on 535 Caucasian samples and generating a new dataset on 100 Chinese children ALL samples, we were able to 1) identify a 62-gene classifier with 97.6% accuracy from the Caucasian samples and validated it on the completely independent set of 100 Chinese samples, 2) to uncover potential regulatory networks of ALL subtypes. The classifier we identified was so far the only one that could be applied directly to a single sample and sustained validation in a large independent patient group. Our results also suggest that the etiology of ALL is largely the same among different ethnic groups, and that the transcription factor hubs in the predicted regulatory network might play important roles in regulating gene expression and development of ALL.

Description
Nuclear reprogramming is an inefficient process with only a small proportion of cells successful converting into induced pluripotent stem (iPS) cells. However, in order to molecularly understand the process these rare intermediates need to be identified and isolated for profiling. In the context of this project we purified the rare reprogramming for three cell types (Fibroblasts, Neutrophils and Keratinocytes) by fluorescent activated cell sorting and submitted them, together with the resulting iPS cells, to RNA sequencing.

Description
The isolation of pure populations of mouse intestinal stem cells (ISCs) is essential to facilitate functional studies of tissue homeostasis, tissue regeneration and intestinal diseases. However, the purification of ISCs has relied predominantly on the use of transgenic reporter alleles in mice. Here, we introduce a new combinational cell surface marker mediated strategy that allows the isolation of an ISC population transcriptionally and functionally equivalent to the gold standard Lgr5-GFP ISCs. We tested the ability of three cell surface marker mediated isolated strategies (termed SM2, SM4 and SM6 according to the number of key cell surface markers used) to purify ISCs and transcriptionally compared them to established standards, Lgr5-GFP high cells and cells negative for any ISC markers (Negative). The best cell surface marker mediated strategy (SM6) allowed the isolation of ISCs from reporter free mice (SM6-WT) that were functionally and transcriptionally distinct from cells isolated from transgenic mice (SM6-TG) due to Lgr5 haploinsufficiency. Overall design: To adequately benchmark the quality of our method with the existing methods, we performed first RNA sequencing with the Lgr5-GFP strain (C57/Bl6 background) on 5 FACS purified groups: SM2, SM4, SM6, Lgr5-GFPhigh reference population and cells negative or low for all of the cell surface markers used. We also performed RNA sequencing of SM6-TG and SM6-WT cells to investigate in detail potential transcriptional differences between them.
