Description
The transcript levels of 560 genes were decreased (less than two-fold), while those of 312 genes were increased (more than two-fold) in the KO-HsfA1d/A1e plants compared with the wild-type plants. The transcript levels of HsfA2, HsfA7a, HsfA7b, HsfB1, and HsfB2a were down-regulated in the KO-HsfA1d/A1e

Description
Dramatic changes of gene expressions are known to occur in human endometrial stromal cells (ESC) during decidualization. The changes in gene expression are associated with changes of chromatin structure, which are regulated by epigenetic mechanisms such as histone modifications. Here, we investigated genome-wide changes in histone modifications and mRNA expressions associated with decidualization in human ESC using chromatin immunoprecipitation (ChIP) combined with next-generation sequencing. ESC were incubated with estradiol and medroxyprogesterone acetate for 14 days to induce decidualization. The ChIP-sequence data showed that induction of decidualization increased H3K27ac and H3K4me3 signals in many genomic regions but decreased in only a few regions. Most (80%) of the H3K27ac-increased regions and half of the H3K4me3-increased regions were located in the distal promoter regions (more than 3 kb upstream or downstream of the transcription start site). RNA-sequence showed that induction of decidualization up-regulated 881 genes, 223 of which had H3K27ac- or H3K4me3-increased regions in the proximal and distal promoter regions. Induction of decidualization increased the mRNA levels of these genes more than it increased the mRNA levels of genes without H3K27ac- or H3K4me3-increased regions. Pathway analysis revealed that up-regulated genes with the H3K27ac- or H3K4me3-increased regions were associated with insulin signaling. These results show that histone modification statuses genome-widely change in human ESC by induction of decidualization. The main changes of histone modifications are increases of H3K27ac and H3K4me3 in both the proximal and distal promoter regions, which are involved in the up-regulation of gene expression that occurs during decidualization. Overall design: mRNA profiles of human endometrial stromal cells with and without EP inductions for 2 individuals. (EP induction: induction with estradiol (10-8 M) and medroxyprogesterone acetate (10-6 M))

Description
Psoriasis is a chronic inflammatory skin disease of unknown etiology. Although macrophages and dendritic cells (DCs) have been proposed to drive the psoriatic cascade, their largely overlapping phenotype hampered studying their respective role. Topical application of Imiquimod, a Toll-like receptor 7 agonist, induces psoriasis in patients and psoriasiform inflammation in mice. We showed that daily application of Imiquimod for 14 days recapitulated both the initiation and the maintenance phase of psoriasis. Based on our ability to discriminate Langerhans cells (LCs), conventional DCs, monocytes, monocyte-derived DCs and macrophages in the skin, we characterized their dynamics during both phases of psoriasis. During the initiation phase, neutrophils infiltrated the epidermis whereas monocytes and monocyte-derived DCs were predominant in the dermis. During the maintenance phase, LCs and macrophage numbers increased in the epidermis and dermis, respectively. LC expansion resulted from local proliferation, a conclusion supported by transcriptional analysis. Continuous depletion of LCs during the course of Imiquimod treatment aggravated chronic psoriatic symptoms as documented by an increased influx of neutrophils and a stronger inflammation. Therefore, by developing a mouse model that mimics the human disease more accurately, we established that LCs play a negative regulatory role during the maintenance phase of psoriasis.

Description
In support of our manuscript investigating the roles of ILCs and T cells in the maintenance of gut hoemostasis, we have performed RNAseq on terminal illeum of mice lacking either all adaptive immune cells (RAG1 -/-), deficient in T cells (TCRalpha -/-), or deficient in T cells but co-housed with wild-type mice and RAG1 -/- mice. Overall design: Tissues from three mice per group were analysed, and the following comparisions were made: RAG1-/- vs. WT C57BL/6 and TCRa-/- co-housed vs TCRa-/- seperately housed. Differential expression genes were identified at 1% FDR using DESeq2.

Description
Numerous CD11b+ myeloid cells are present within the dermis. They are very heterogeneous and can be divided in dermal DCs, tissue monocytes and tissue macrophages. At steady state, only CD11b+ DC migrate from the dermis to the skin draining lymph nodes whereas upon DNFB-induced inflammation, CD11b+ DC as well as dermal monocytes migrated to the lymph nodes. The objective of this study was to use gene expression profiling to rigorously identify the different subsets of dermal CD11b+ myeloid cells at steady state and upon inflammation and to characterize their functional potential.
