Description
Our study looks at the dirsruption of lung circadian transcriptome that occurs when neutrophils are depleted (by application of antibodies (anti-Ly6G-1A8) to wildtype C57BL/6 mice, or Diphtheria toxin (DT) to neutrophil-specific DT-susceptible mice (MRP8-Cre;iDTR-flox)). Overall design: Lungs were harvested from neutrophil-depleted (antibody or DT) or non-depleted mice, in normal light-controlled mouse facility (ZT4) or 12h inverted light cabinets (ZT16). Experiments were carried out over 3 batches (July 2017, September 2017, and April 2018), with 3 or 4 mice per group. Antibody-depleted and non-depleted mice were tested for the July 2017 and September 2017 batches, whereas DT-depleted mice were tested only in April 2018.

Description
Our study aims to analyze time-dependent changes in neutrophil phenotype, compare them with included neutrophil-specific mutants, and indentify common signatures among the 5 groups Overall design: Blood neutrophils from wild-type and mutants were isolated based on Ly6G staining, then standard RNA extraction procedures were performed. Wild-type samples were extracted at ZT5 and ZT13, all other samples at ZT5.

Description
Purpose: In our study, we identified a heterogeneity among bone marrow (BM) Ly6Chi monocytes, which can be subdivided the expression of CXCR4. In order to understand the development of BM monocytes, the goal of this experiment is to compare the transcriptome of these 2 BM Ly6Chi monocyte subsets to those of the common monocyte progenitor (cMoP) and Ly6Clo monocytes. Overall design: 4 BM monocyte subsets (cMoP, Ly6ChiCXCR4hi, Ly6ChiCXCR4lo and Ly6Clo) from 3 different mice were sorted using a BD Aria III. Total RNA was extracted, converted to cDNA and run through deep sequencing using Illumina HiSeq 2500

Description
We profiled the transcriptome of Drosophila melanogaster embryos in ttk2D50 embryos or after over-expression using btl-GAL4; UAS-ttk, respectively. We further isolated cells that express btl-enh-RFPmoe (Cabernard and Affolter 2005) and FACS sorting, and profiled their transcriptomes in the same genetic backgrounds.

Description
Intra-islet crosstalk between islet cells is critical in orchestrating the body’s response to changes in blood glucose levels, but is incompletely understood. In this study, we used transgenic mouse lines that allowed the purification and transcriptomic characterisation of alpha, beta, and delta cells, yielding an RNA-sequencing database that can be searched for regulatory proteins which are differentially expressed between cell types. As an illustrative example, we examined the expression of g-protein coupled receptors, and found that the ghrelin receptor, Ghsr, was highly expressed in delta cells compared to alpha and beta cells. GHSR excitation elicited increases in cytosolic calcium levels in primary delta cells. In the perfused pancreas, the application of ghrelin stimulated somatostatin secretion, correlating with a decrease in insulin and glucagon release, which was sensitive to somatostatin receptor antagonism. These results show that ghrelin acts specifically on delta cells within pancreatic islets to affect blood glucose regulation. Overall design: Examination of transcriptomic profiles obtained from pancreatic alpha, beta and delta cells
Publication Title
Transcriptomic profiling of pancreatic alpha, beta and delta cell populations identifies delta cells as a principal target for ghrelin in mouse islets.

Description
Innate lymphoid cells (ILCs) are important regulators in various immune responses. Current paradigm states that all newly-made ILCs originate from common lymphoid progenitors (CLP) in the bone marrow. Id2, an inhibitor of E protein transcription factors, is indispensable for ILC differentiation. Unexpectedly, we found that ectopically expressing Id1 or deleting two E protein genes in the thymus drastically increased ILC2 counts in the thymus and other organs where ILC2 normally reside. Further evidence suggests a thymic origin of these mutant ILC2s. The mutant mice exhibit augmented spontaneous infiltration of eosinophils and heightened responses to papain in the lung and increased ability to expulse the helminth parasite, Nippostrongylus brasiliensis. These results prompt the question whether the thymus naturally has the capacity to produce ILC2s and E proteins restrain such a potential. The abundance of ILC2s in Id1 transgenic mice also offers a unique opportunity for testing the biological functions of ILC2s. Overall design: For RNA-seq analyses, ILC2s (Lin-Thy1+ST2+) were sorted from thymocytes and mesenteric lymph node cells and processed for RNA-seq. In addition, MLN cells were also cultured in the presence of IL-, IL-25 and IL33. Duplicate samples were analyzed.

Description
Developmental transitions can be described in terms of morphology and individual genes expression patterns, but also in terms of global transcriptional and epigenetic changes. Most of the large-scale studies of such transitions, however, have only been possible in synchronized cell culture systems. Here we generate a cell type specific transcriptome of an adult stem-cell lineage in the Arabidopsis leaf using RNA sequencing and microarrays. RNA profiles of stomatal entry, commitment, and differentiating cells, as well as of mature stomata and the entire aerial epidermis give a comprehensive view of the developmental progression.
