Description
This study examines the transcriptional changes invoked by activation of gp130 signaling in different mouse models of B cell lymphomagenesis. In order to study the in vivo effects of aberrant activity of IL-6/IL-6R/gp130-JAK/STAT3 signaling, we designed a transgene that allows conditional expression of L-gp130 by generating a ROSA26 knock-in mouse strain where compound L-gp130 and ZsGreen expression from the CAG promoter is prevented by a loxP- and a rox-flanked stop cassette. Total RNA extracted from purified B cells from young CD19Cre+/- ;L-gp130fl/+ and wildtype control mice was sequenced using unique molecular identifiers (UMI) in a paired end design where read1 corresponds to the cDNA and read2 contains the UMI. Furthermore, aging CD19Cre+/- ;L-gp130fl/+ animals developed tumors located predominantly in mesenteric lymph nodes. Infiltration of CD19;L-gp activated B cells was determined by Flow Cytometry and ZsGreen expression. Total RNA from tumors generally containing >60% ZsGreen+ cells was profiled as described above, for tumors with lower CD19;L-gp activated B cell content FACS was applied. In order to study the effects of activated IL-6/IL-6R/gp130-JAK/STAT3 signaling on Eµ-Myc-driven lymphomagenesis, CD19Cre;L-gp130fl;Eµ-Myc triple transgenic mice were generated and fetal liver hematopoietic stem/progenitor cell (FL-HSPC) grafts were transplanted into lethally irradiated syngeneic mice alongside FL-HSPC from CD19Cre;L-gp130f and Eµ-Myc control mice. Lastly, IL-6/IL-6R/gp130-JAK/STAT3 signaling was activated in the entire hematopoetic system using Vav1Cre resulting in Vav1Cre+/- ;L-gp130fl/+ animals. Independent of the time point of activation during hematopoietic and B cell differentiation, all Cre;L-gp compound mice succumbed to tumors of B cell origin. Overall design: Bulk gene expression data are presented for (i) purified B cells from wildtype control mice (n=6) and young CD19;L-gp mice (n=4), (ii) tumors detected in aging CD19;L-gp mice with a mature (n=11) and plasma cell phenotype (n=6), respectively, (iii) tumors arising in lethally irradiated syngeneic mice after transplantation of fetal liver hematopoietic stem/progenitor cells from CD19;L-gp;Myc (n=9), CD19;L-gp (n=7) and Eµ-Myc (n=9) mice, respectively, and (iv) malignant B cells from Vav1;L-gp mice (n=13).

Description
In vitro differentiation of embryonic stem cells (ESC) provides models that reproduce in vivo development and cells for therapy. Whether the epigenetic signatures that are crucial for brain development and function and that are sensitive to in vitro culture are similar between native brain tissues and their artificial counterpart generated from ESC is largely unknown. Here, using RNA-seq we have compared the parental origin-dependent expression of imprinted genes (IGs), a model of epigenetic regulation, in cerebral cortex generated either in vivo, or from ESCs using in vitro corticogenesis, a model that reproduces the landmarks of in vivo corticogenesis. For a majority of IGs, the expressed parental alleles were the same for in vivo and in vitro cortex. In most cases, this choice was already set in ESCs and faithfully maintained during the 3 weeks of in vitro corticogenesis. Confirming these findings, methylation, which selects the parental allele to be transcribed, was also largely equivalent between the 2 types of cortex and ESCs. Our results thus indicate that the allele specific expression of imprinted transcripts, a model of epigenetic regulation resulting from a differential methylation of parental genomes, is mostly mimicked in cortical cells derived from ESC. Overall design: We have crossed two strains of mice (B6 and JF1) that display more than 12 million of SNPs (Takada et al., Genome Res. 2013 Aug;23(8):1329-38. doi: 10.1101/gr.156497.113). We have then analyzed allele specific expression transcriptome-wide using RNA-seq on hybrid F1 cortex generated either in vivo or in vitro from ESCs. In addition, we have used 2 different developmental stages of in vivo cortex (E13.5, P0) and three stages in vitro (undiffererentiated ESC, and differentiated into cortex for 12 and 21 days) to measure the dynamics of parental expression. Please note that [1] the same raw data files were used to generate the ''*allele-specific_sense_read_bases_by_gene_withoutContamination.txt'' processed data files.

Three libraries from wildtype embryos and three libraries from dusp2um287/um287;dusp6um286/um286 embryos were then generated from 3mg RNA using the TruSeq Stranded mRNA Library Prep Kit (Illumina). All libraries were analyzed for quality on a bioanalyzer prior to sequencing (Agilent 2100 BioAnalyzer).

Description
Virus infection and over expression of protein in cytosol induce a subset of HSP70s. We named this response the Cytosolic Protein Response (CPR) and have been investigating it in the context of a parallel mechanism in the soluble cytosol with the UPR, and as a subcomponent of the larger HS response. This experiment was carried out to study the transcriptional aspect of CPR. In this analysis, we have triggered CPR by infiltrating proline analogue, L-azetidine-2-carboxylic acid (AZC) into Arabidopsis mature leaves. Since AZC trigger unfolded protein response(UPR) in ER as well as CPR, we have included tunicamycin treatment, which is a specific inducer of UPR to subtract the effect of UPR from the AZC response. Heat shocked samples were included to identify CPR as a subcomponent of larger HS response.

Description
To generate an unbiased view of changes to the retinal gene network in Neurog2 retinal mutants, we generated and compared the P2 transcriptomes from control, heterozygote and mutant mice. A pair of P2 retinas from each biologic replicate were used to produce libraries for high throughput sequencing (n = 5 biologic replicates/genotype). Reads were aligned with BWA and Bowtie programs to the mm10 genome. Aligned reads were then analyzed for differentially expressed transcripts using the CuffDiff program in the Galaxy online bioinformatics package (www.usegalaxy.org). Overall design: Total RNA from Neurog2CKO/CKO(wildtype; n = 5), Chx10Cre;Neurog2CKO/+(heterozygote; n = 5), and Chx10Cre;Neurog2CKO/CKO(mutant; n = 5) P2 retinas.

Long-term dynamic compression enhanced the mechanical properties of MSC-seeded constructs only when loading was initiated after 21 days of chondrogenic differentiation. This study examined the molecular differences of chondrogenic MSCs compared to undifferentiated MSCs (TGF-beta vs no TGF-beta) and the effects of dynamic loading on MSC chondrogenesis (loading vs free-swelling).
