We analysed the transcriptome of dormant and after-ripened imbibed seeds of different genotypes (Landsberg erecta and the different NILs) to identify dormancy and after-ripening genes that are absolutely required for these traits.

View SamplesRNA-seq analysis of 16 B6J x B6NJ-F2 mice which are homozygous for either the wild-type B6J allele (binge-resistant; J/J) or mutant B6NJ allele (binge-prone; N/N), at rs240617401, a marker denoting a missense SNP in Cyfip2. Genotype identity is denoted as either J for binge-resistant; J/J, or N for binge-prone; N/N. Overall design: A sample size of N=8 per genotype was employed (4 females, 4 males; 69-100 days old at the time of sacrifice). Striatum punches were harvested on Day 24 immediately following the 5-min behavioral test on the EPM, stored in RNAlater for 48 h, blotted dry with a kimwipe, and transferred to -80ºC. Total RNA was isolated and shipped to the University of Chicago Genomics Core Facility for cDNA library preparation using the Illumina TruSeq Stranded mRNA LT Sample Prep Kit (50 bp single-end reads). Samples were sequenced using the Illumina HiSeq 4000 with 16 samples per lane over four lanes (technical quadruplicates). FASTQ files were quality checked via FASTQC and all samples exhibited Phred quality scores greater than 30 (i.e. less than 0.1% sequencing error). FASTQ files were used to align reads to the reference genome using TopHat (mm10; UCSC Genome Browser). Read counts per gene were quantified using the HTSeq Python package.

View SamplesRNA-seq analysis of 8 Cyfip2N/- and 8 Cyfip2N/N mice. Cyfip2N/- are mice contain one copy of the B6NJ missense mutation and one copy of the nonsense mutation (binge-resistant; N/-), whereas Cyfip2N/N are mice that have two mutated B6NJ allele (binge-prone; N/N), at rs240617401, a marker denoting a missense SNP in Cyfip2. Genotype identity is denoted as either J for binge-resistant; N/-, or N for binge-prone; N/N.

View SamplesOrogastral infection of mice with Yersinia enterocolitical leads to HIF-1 alpha activation.To elucidate whether this HIF-1 alpha activation also results in a HIF-1 dependent gene programming, the transcriptomes from Peyers Patches of uninfected and Yersinia enterocolitica infected mice were analyzed by means of of microarray analyses using Affymetrix GeneChip probe arrays (MG-U74Av2). In total, 288 genes were differentially regulated three day after infection in PP compared with the expression of uninfected control mice. Of these 288 genes, 217 were found to be differentially upregulated and from these, 14 genes ( 6.5% of all upregulated genes) are well described to be regulated via HIF-1. These data indicate that orogatral infection with Y. enterocolitica results in HIF-1 dependent gene programmning

View SamplesGroup 2 innate lymphoid cells (ILC2) are tissue-resident innate lymphocytes that are derived from common lymphoid progenitor (CLP). While specific progenitors and transcription factors essential for ILC2 differentiation have been well studied, external factors that regulate the commitment from CLP to ILC lineage, site that promote ILC2 terminal differentiation, and stromal cells that provide optimal microenvironment for ILC2 specific development are not fully understood. we demonstrated that the three key external factors such as concentration of IL-7 and the strength and duration of Notch signaling conditionally determined the fate of CLP toward T cell, B cell, or ILC lineages, which seems to be an important process from CLP to CHILP differentiation in the fetal liver. Furthermore, we identified ILC progenitors lacking the developmental potential to become T or B cells, and KLRG1- immature ILC2 that require STAT5 for functional maturation in the mesentery. We also identified PDGFRa+gp38+ mesenchymal cells in the mesentery that support ILC2 differentiation from ILC progenitors but not from CLP. Finally, single-cell RNA-sequencing (scRNA-seq) analysis of mesenteric cells demonstrated that PDGFRa+gp38+ cells are heterogeneous populations. Collectively, our result suggested that early differentiation of ILC2 occurs in the primary lymphoid organ with regulation of environmental factors, and final differentiation occurs in the peripheral tissues once after CHILP migrate into the periphery. Overall design: Duplicate samples (mouse 1 and mouse 2) were processed for single cell-based RNA sequencing with Illumina HiSeq 2500 with 50 paired-end reads, using barcorded RNA library.
