Description
Cell adhesion plays an important role in determining cell shape and function in a variety of physiological and pathophysiological conditions. While links between metabolism and cell adhesion were previously suggested, the exact context and molecular details of such a cross-talk remain incompletely understood.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Secreted proteins serve pivotal roles in the development of multicellular organisms, acting as structural matrix, extracellular enzymes and signal molecules. In this study we demonstrate, unexpectedly, that PGC-1, a critical transcriptional co-activator of metabolic gene expression, functions to down-regulate expression of diverse genes encoding secreted molecules and extracellular matrix (ECM) components to modulate the secretome. We show that both endogenous and exogenous PGC-1 down-regulate expression of numerous genes encoding secreted molecules. Mechanistically, results obtained using mRNA stability measurements as well as intronic RNA expression analysis are consistent with a transcriptional effect of PGC-1 on expression of genes encoding secreted proteins. Interestingly, PGC-1 requires the central heat shock response regulator HSF1 to affect some of its targets, and both factors co-reside on several target genes encoding secreted molecules in cells. Finally, using a mass spectrometric analysis of secreted proteins, we demonstrate that PGC-1 modulates the secretome of mouse embryonic fibroblasts (MEFs).

- Affymetrix Bovine Genome Array (bovine)
Description
The aim of this transcription profiling study was to identify novel genes that could be used to distinguish bovine Nucleus pulposus (NP) cells from articular cartilage (AC) and annulus fibrosus (AF) cells and to further determine their expression in normal and degenerate human intervertebral disc (IVD). This study has identified a number of novel genes that characterise the bovine and human NP and IVD cell phenotypes and allows for discrimination between AC, AF and NP cells.<br></br><br></br>

Description
The catalytic activities of covalent and ATP-dependent chromatin remodeling are central to regulating the conformational state of chromatin and the resultant transcriptional output. The enzymes that catalyze these activities are often contained within multiprotein complexes in nature. Two such multiprotein complexes, the polycomb repressive complex 2 (PRC2) methyltransferase and the SWItch/Sucrose Non-Fermentable (SWI/SNF) chromatin remodeler have been reported to act in opposition to each other during development and homeostasis. An imbalance in their activities induced by mutations/deletions in complex members (e.g. SMARCB1) has been suggested to be a pathogenic mechanism in certain human cancers. Here we show that preclinical models of synovial sarcoma - a cancer characterized by functional SMARCB1 loss via its displacement from the SWI/SNF complex through the pathognomonic SS18-SSX fusion protein - display sensitivity to pharmacologic inhibition of EZH2, the catalytic subunit of PRC2. Treatment with tazemetostat, a clinical-stage, selective and orally bioavailable small-molecule inhibitor of EZH2 enzymatic activity reverses a subset of synovial sarcoma gene expression and results in concentration-dependent cell growth inhibition and cell death specifically in SS18-SSX fusion-positive cells in vitro. Treatment of mice bearing either a cell line or two patient-derived xenograft models of synovial sarcoma leads to dose-dependent tumor growth inhibition with correlative inhibition of trimethylation levels of the EZH2-specific substrate, lysine 27 on histone H3. These data demonstrate a dependency of SS18-SSX-positive, SMARCB1-deficient synovial sarcomas on EZH2 enzymatic activity and suggests the potential utility of EZH2-targeted drugs in these genetically defined cancers. Overall design: Three different in vivo models of synovial sarcoma (xenograft: Fuji; PDX: CTG-0331 and CTG-0771) treated with or without the indicated dose of the EZH2 inhibitor, tazemetostat

Description
Group 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.
