Description
Infection of humans with Ehrlichia chaffeensis, the etiologic agent of human monocytic ehrlichiosis, can cause hepatitis of varying severity. When the three human isolates of E. chaffeensis, each belongs to different geno-groups, are inoculated into severe combined immunodeficiency mice, the severity of clinical signs and bacterial burden detected in the liver are strain Wakulla>Liberty>Arkansas. Disseminated and granulomatous inflammation is evident in the liver of mice infected with strains Wakulla and Arkansas, respectively, but not in mice infected with strain Liberty. In this paper, we used microarray analysis to define transcriptional profiles characteristic to the histopathological features in the mouse liver. Cytokine and chemokine profiles were strikingly different among three strains of E. chaffeensis: IFN-, CCL5, CXCL1, CXCL2, CXCL7 and CXCL9 were highly up-regulated with strain Arkansas, TNF-, CCL2, CCL3, CCL5, CCL6, CCL12, CCL20, CXCL2, CXCL7, CXCL9 and CXCL13 were highly up-regulated with strain Wakulla. With strain Liberty, only CXCL13 was highly up-regulated. In the livers infected with the Arkansas strain, monocytes/macrophages and NK cells were enriched in the granulomas and increase of NK cell-marker mRNAs was detected. Livers infected with the Wakulla strain displayed infiltration of significantly more neutrophils and increase of neutrophil-marker mRNAs. Genes up-regulated commonly in the liver infected with the three stains are other host innate immune and inflammatory response genes including several acute phase proteins. Genes down-regulated commonly are related to host physiologic functions. The results suggest that marked modulation of host cytokine and chemokine profiles by E. chaffeensis strains underlie the distinct host liver disease.

Description
In mammals, chromosomes are partitioned into megabase-sized topologically associating domains (TADs). TADs can be in either A (active) or B (inactive) subnuclear compartments, which correspond to early (E) and late (L) replicating timing (RT) domains, respectively. Here, we show that RT changes are tightly correlated with A/B compartment changes during mouse embryonic stem cell (mESC) differentiation. A/B compartments changed mostly by a “boundary shift,” frequently causing compartment switching of single TADs, which coincided with or preceded RT changes. Upon differentiation, mESCs acquired an A/B compartment organization that closely resembled EpiSCs (epiblast-derived stem cells), suggesting that accumulation of compartment boundary repositioning eventually led to naïve-to-primed pluripotency transition in A/B compartment organization. We propose that large-scale reorganization of A/B compartments, which is reflected in RT domain reorganization, represents major cell fate changes. Collectively, our data provides valuable insights into the regulatory principles of 3-dimensional (3D) genome organization during early embryonic stages. Overall design: RNA-Seq: 9 cell types, with a total of 34 individual replicates.

Description
Decoy receptor 3 (DcR3), a member of the tumor necrosis factor receptor (TNFR) superfamily, competitively binds and inhibits members of the TNF family, including Fas ligand (FasL), LIGHT, and TL1A. DcR3 was recently reported not only to act as a decoy receptor for these TNFRs but also to play a role as a ligand for the pathogenesis of RA.

Description
Fas ligand (FasL)/TNFSF6, a member of the tumor necrosis factor (TNF) superfamily, can promote apoptosis in activated primary B cells, T cells, dendritic cells, and synovial fibroblasts through Fas and is involved in the pathogenesis of autoimmune diseases including rheumatoid arthritis (RA). Meanwhile, decoy receptor 3 (DcR3) competitively binds soluble FasL in addition to TL1A and LIGHT and inhibits the signaling of FasL via Fas. Therefore, FasL-DcR3/Fas signaling may be involved in the pathogenesis of RA.

Description
We report a method for deriving oligodendrocyte lineage cells from human pluripotent stem cells (hPSCs) in three-dimensional (3D) culture called human oligodendrocyte spheroids (hOLS). To characterize oligodendrocyte-lineage cells in hOLS, we isolated O4+ cells by immunopanning and performed deep single cell RNA sequencing. We sequenced 295 cells and compared their profiles to unsorted cells isolated from primary human fetal cortex, primary human adult cortex, and hCS. Clustering of all cells using the t-distributed stochastic neighbor embedding (tSNE) approach revealed a distinct populations of SOX10+ oligodendrocytes, within which the O4+ cells derived from hOLS clustered most closely to oligodendrocyte progenitor cells (OPCs) and mature oligodendrocytes from the primary human adult cortical tissue. Additionally, subpopulations of OPCs, newly formed oligodendrocytes, and myelinating oligodendrocytes derived were observed in the hOLS-derived cluster. To further assess the state of oligodendrocyte-lineage cells in hOLS, we performed a Monocle analysis which revealed a spectrum of oligodendrocyte-lineage stages in hOLS ranging from dividing cells that closely resembled primary OPCs to mature cells that closely resembled primary oligodendrocytes. Overall design: Examination of gene expression in single oligodendrocyte-lineage cells derived from human pluripotent stem cells in three-dimensional culture

Description
Tongue squamous cell carcinoma (TSCC) varies in characteristics even in early stages and is mainly classified into three subtypes, which are superficial, exophytic and endophytic types, based on a macroscopic appearance of tumor growth.Of these subtypes, endophytic tumor has a poorer prognosis because of its invasive feature and higher frequency to have metastasis. To understand a molecular mechanism of endophytic subtype and identify biomarkers, we performed comprehensive microarray analysis for mRNAs from clinical biopsy sampleswhich were classified into subtypes and found overexpression of parvin-beta (PARVB) gene significantly related to endophytic type. PARVB is known to play a critical role in actin reorganization and focal adhesions. Knocking down PARVB expression in vitrocaused apparent decreases in cell migration and wound healing, implying that PARVB has a crucial role in cellular motility. Moreover, metastasis-free survival was significantly lowered in patients with higher PARVB expression. Therefore overexpression of PARVB is a candidate biomarker for endophytic tumor and metastasis and may be clinically applicable for decision making of an adjuvant therapy in TSCC.

Description
We performed the newly mapping of genome-wide NFATc1 binding events in VEGF-stimulated primary cultured endothelial cells, by chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-seq). Combined NFATc1 ChIP-seq profile and the epigenetic histone marks revealed that predominant NFATc1-occupied peaks were overlapped with promoter marking but not silencer marking. DNA microarrays with NFATc1 expression or knockdown indicated the predominant NFATc1 binding targets were correlated with induced patterns.
