Illumina HiSeq 2500
Description
This study aims to investigate the role of microRNA-30c on hepatic and metabolic gene expression and physiology Overall design: For this experiment, we used male C57BL/6 mice. At an age of 8 weeks, we started them on Western diet for one month and then injected them with either PBS or increasing dose of Scr or miR-30c mimic (2.5, 5.0, and 7.5 mg/kg) for 6 weeks. Liver from these mice were harvested and flash frozen. RNA from the livers of these mice were extracted and RNA-seq was performed.

Description
The highly characterized Sox9-EGFP transgenic mouse model, which permits the isolation and analysis of four distinct IEC populations using fluorescence-activated cell sorting (FACS) based on differing levels of cellular EGFP intensity. These are Sox9-EGFP Low (actively cycling IESCs), Sox9-EGFP Sublow (progenitor cells), Sox9-EGFP Neg (mostly differentiated enterocytes as well as goblet cells and Paneth cells), and Sox9-EGFP High (primarily EECs). We evaluated mRNA expression profiles by next-generation high-throughput RNA-sequencing in FACS purified Sox9-Low cells from germ-free (GF) and conventionalized (CV) mice. Overall design: To assess the effect of microbiota on the intestinal epithelial stem cells population, we used four pairs of female GF Sox9-EGFP littermates. One littermate from each pair was randomly selected at 8-10 weeks of age for conventionalization. Following a two-week conventionalization, the jejunal epithelial tissue from both the CV and GF littermates were harvested and IECs were sorted by FACS. RNA was isolated from the four sorted populations from each animal, as well as from non-sorted (NS) IECs, and subject to small RNA sequencing. Additionally, Sox9-Low samples were profiled for mRNAs using mRNA-seq. Reads were aligned to the mouse genome and quantified using Salmon followed by edgeR. To avoid noise introduced by lowly expressed transcripts, we analyzed only robustly expressed transcripts defined as those with an expression of at least 10 counts per million (CPM).

- Bovine Gene 1.0 ST Array (bovgene10st)
Description
The innate repair and regeneration potential of skeletal tissues such as the intervertebral disc and articular cartilage is extremely limited, in part due to their avascularity and low cell density. Despite recent advances in MSC-based disc and cartilage regeneration, key challenges remain, including the sensitivity of these cells to in vivo microenvironmental stress such as low oxygen and nutrient levels. The objective of this study was to investigate whether preconditioning with hypoxia and/or transforming growth factor-beta (TGF-) can enhance MSC survival and extracellular matrix production in a low oxygen and nutrient-limited microenvironment. Secondarily, the effects of donor variability on the response of MSCs to preconditioning was examined. MSCs from multiple bovine donors were preconditioned in monolayer in normoxia or hypoxia, with or without TGF-.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Background: Diesel exhaust (DE) is the primary source of urban fine particulate matter, which has been associated with cardiovascular disease in epidemiological studies. These effects may be related to oxidative stress and systemic inflammation with resulting perturbation of vascular homeostasis. Peripheral leukocytes are involved in both inflammation and control of vascular homeostasis. Objectives: We conducted an exploratory study using microarray techniques to analyze whether global gene expression in peripheral blood mononuclear cells (PBMCs) can inform on potential mechanisms of effect of DE inhalation. Methods: In a double-blind, crossover, controlled exposure study, healthy adult volunteers were exposed in randomized order to filtered air (FA) and diluted DE in two-hour sessions. We isolated RNA (Trizol/Qiagen method) form PBMCs before, and two times after each exposure. RNA samples were arrayed using the Affymetrix platform (GeneChip Human Genome U133 Plus 2.0 Array). Results: Microarray analyses were conducted on five subjects with available RNA sample form exposures to FA and to the highest DE inhalation (200 g/m of fine particulate matter). Following data normalization and statistical analysis, a total of 1290 out of 54,675 probe sets with significant evidence for differential expression (more than 1.5-fold up or down regulated with p < 0.05) were identified. These include genes involved in inflammatory response (e.g., IL8RA, TNFAIP6, FOS), oxidative stress (e.g., HMOX1, BAX, PRDX1,), and in biochemical pathways like mitogen-activated protein kinases (MAPK) and tight junction pathways. Conclusions: These data suggest that DE may exert time-dependent changes in gene expression in PBMCs in healthy individuals. Genes that may be affected by DE inhalation are involved in inflammatory and oxidative stress processes.

Description
Primary Sjgrens syndrome (pSS) is a chronic autoimmune disease with complex etiopathogenesis. Here we use Affymetrix U133 plus 2.0 microarray gene expression data from human parotid tissue. Parotid gland tissues were harvested from 17 pSS and 14 14 non-pSS sicca patients and 18 controls. The data were used in the following article: Nazmul-Hossain ANM, Pollard RPE, Kroese FGM, Vissink A, Kallenberg CGM, Spijkervet FKL, Bootsma H, Michie SA, Gorr SU, Peck AB, Cai C, Zhou H, Horvath S, Wong DTW (2012) Systems Analysis of Primary Sjgrens Syndrome Pathogenesis in Salivary Glands: Comparative Pathways and Molecular Events in Humans and a Mouse Model.
