Description
The nuclear hormone 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) regulates its target genes via activation of the transcription factor vitamin D receptor (VDR) far more specifically than the chromatin modifier trichostatin A (TsA) via its inhibitory action on histone deacetylases. We selected the thrombomodulin gene locus with its complex pattern of three 1,25(OH)2D3 target genes, five VDR binding sites and multiple histone acetylation and open chromatin regions as an example to investigate together with a number of reference genes, the primary transcriptional responses to 1,25(OH)2D3 and TsA. Transcriptome-wide, 18.4% of all expressed genes are either up- or down-regulated already after a 90 min TsA treatment; their response pattern to 1,25(OH)2D3 and TsA sorts them into at least six classes. TsA stimulates a far higher number of genes than 1,25(OH)2D3 and dominates the outcome of combined treatments. However, 200 TsA target genes can be modulated by 1,25(OH)2D3 and more than 1000 genes respond only when treated with both compounds. The genomic view on the genes suggests that the degree of acetylation at transcription start sites and VDR binding regions may determine the effect of TsA on mRNA expression and its interference with 1,25(OH)2D3. Our findings may have implications on dual therapies using chromatin modifiers and nuclear receptor ligands.

Description
Natural killer T (NKT) cells have immune stimulatory or inhibitory effects on the immune response that are context-dependent. This may be attributed in part to the existence of functional NKT cell subsets; however, these functional subsets have only been characterized on the basis of differential expression of a few transcription factors and cell surface molecules. Here we have analyzed purified populations of thymic NKT cell subsets at both the transcriptomic and epigenomic levels, and by single-cell RNA sequencing. Our data indicate that despite their similar antigen specificity, the functional NKT cell subsets are highly divergent populations characterized by many gene expression and epigenetic differences. Therefore the thymus imprints innate-like NKT cells with novel combinations of properties, including differences in proliferative capacity, homing, and effector functions that were not previously anticipated. Overall design: Analysis of single cell transcriptomic heterogeneity in mouse Va14 iNKT thymocyte subsets (NKT1, NKT2, NKT17 and NKT0). Samples were generated from individual experiment using a pool of thymocytes prepared from five five-week old C57BL/6J females. NKT cells subtypes were isolated from thymuses and directly sorted by flow cytometry into lysis buffer (96 well plate single cell sort). The preparation of samples occurred in 2 different batches (both having a equal representation of the different cell populations).

Description
Allergic asthma and rhinitis are two common chronic allergic diseases that affect the lungs and nose, respectively. Both diseases share clinical and pathological features characteristic of excessive allergen-induced type 2 inflammation, orchestrated by memory CD4+ T cells that produce type 2 cytokines (TH2 cells). However, a large majority of subjects with allergic rhinitis do not develop asthma, suggesting divergence in disease mechanisms. Since TH2 cells play a pathogenic role in both these diseases and are also present in healthy non-allergic subjects, we performed global transcriptional profiling to determine whether there are qualitative differences in TH2 cells from subjects with allergic asthma, rhinitis and healthy controls. TH2 cells from asthmatic subjects expressed higher levels of several genes that promote their survival as well as alter their metabolic pathways to favor persistence at sites of allergic inflammation. In addition, genes that enhanced TH2 polarization and TH2 cytokine production were also upregulated in asthma. Several genes that oppose T cell activation were downregulated in asthma, suggesting enhanced activation potential of TH2 cells from asthmatic subjects. Many novel genes with poorly defined functions were also differentially expressed in asthma. Thus, our transcriptomic analysis of circulating TH2 cells has identified several molecules that are likely to confer pathogenic features to TH2 cells that are either unique or common to both asthma and rhinitis. Overall design: RNA-sequencing of circulating TH2 cells isolated from a cohort of patients with allergic rhinitis (25), asthma (40) patients and healthy non allergic subjects (15). Cells were directly isolated from blood by flow cytometry. Total RNA was extracted, messenger RNA was selected and cDNA was amplified linearly with a PCR based method (Picelli et al. 2014). Libraries were prepared using the NexteraXT Illumina sequencing platform.

Description
Methamphetamine can trigger dopamine releasing in human brain, now used as abuse drug. Some studies have shown that specific genes and proteins responded to, methamphetamine, but little is known about the overall omic response of organisms to this illicit substance. Here we demonstrate that Drosophila melanogaster has the potential to give us significant insights into evolutionarily conserved responses to methamphetamine. We performed metabolome, proteome, and transciptome profiling with Drosophila treated with methamphetamine. The proteomic profiling revealed responses associated with known physiological problems that occur with methamphetamine usage in mammals. The metabolomic result showed that the metabolite trehalose was decreased significantly after methamphetamine exposure, suggesting an oxidative stress response to this drug. Many of the differential transcribed genes, including detoxification enzymes, had the potential transcription factor-binding motif YY1 associated with their upstream regulatory regions. YY1 is known to be responsive to amphetamines in mammals.
