Description
AIRmax and AIRmin mouse lines show a differential lung inflammatory response and differential lung tumor susceptibility after urethane treatment, thus constituting a good genetic model to investigate differences in gene expression profiles related to inflammatory response and lung tumor susceptibility. The transcript profile of ~24,000 known genes was analyzed in normal lung tissue of untreated and urethane-treated AIRmax and AIRmin mice. In lungs of untreated mice, inflammation associated genes involved in pathways such as leukocyte transendothelial migration, cell adhesion and tight junctions were differentially expressed in AIRmax versus AIRmin mice. Moreover, gene expression levels differed significantly in urethane-treated mice even at 21 days after treatment. In AIRmin mice, modulation of expression of genes involved in pathways associated with inflammatory response paralleled the previously observed persistent infiltration of inflammatory cells in the lung of these mice. In conclusion, a specific gene expression profile in normal lung tissue is associated with mouse line susceptibility or resistance to lung tumorigenesis and with different inflammatory response, and urethane treatment causes a long-lasting alteration of the lung gene expression profile that correlates with persistent inflammatory response of AIRmin mice.

Description
To increase our understanding of psoriasis, we utilized RNA-seq to assay the transcriptomes of lesional psoriatic and normal skin. We sequenced polyadenylated RNA-derived cDNAs from 92 psoriatic and 82 normal punch biopsies, generating an average of ~38 million single-end 80-bp reads per sample. Comparison of 42 samples* examined by both RNA-seq and microarray [GSE13355] revealed marked differences in sensitivity, with transcripts identified only by RNA-seq having much lower expression than those also identified by microarray. RNA-seq identified many more differentially expressed transcripts enriched in immune system processes. Weighted gene co-expression network analysis (WGCNA) revealed multiple modules of coordinately expressed epidermal differentiation genes, overlapping significantly with genes regulated by the long non-coding RNA TINCR, its target gene, staufen-1 (STAU1), the p63 target gene ZNF750, and its target KLF4. Other coordinately expressed modules were enriched for lymphoid and/or myeloid signature transcripts and genes induced by IL-17 in keratinocytes. Dermally-expressed genes were significantly down-regulated in psoriatic biopsies, most likely due to expansion of the epidermal compartment. These results demonstrate the power of WGCNA to elucidate gene regulatory circuits in psoriasis, and emphasize the influence of tissue architecture in both differential expression and co-expression analysis. *The list of 42 samples examined by both RNA-seq and microarray is provided in the 'MAoverlappedsamples.txt'. Overall design: 92 psoriatic and 82 normal skin samples

Description
Imiquimod (IMQ) is a topical therapeutic immune activator that causes psoriasiform inflammation in mice. To determine if IMQ-induced inflammation and gene expression changes depended on the time of day in which treatment is administered, we performed gene expression profiling of dorsal mouse back skin by microarray after different durations of topical 1% IMQ treatment (control = no treatment, 6 hr, 24 hr, and 5 days of IMQ treatment) at different times of day (ZT01, ZT07, ZT09 = day-time treatment; ZT13 and ZT19 = night-time treatment). We also performed a time course after IMQ treatment by collecting mouse back skin after 0 (no treatment), 1, 2, 4, 6, and 24 hours post-treatment. Lastly, we determined gene expression changes in response to IMQ in mice deleted for the core circadian clock gene, Bmal1, after 0 (no treatment) and 24 hours post-1% IMQ compared to Wt (both treated and collected during the daytime at ZT09). The results of this study are important as they show that IMQ-induced activation of interferon sensitive genes are diurnal in Wt mice after 6 hours and 24 hours but not after 5 consecutive treatments. Furthermore, we find that interferon sensitive genes are induced more robustly in the skin of Bmal1 KO mice after 24 hr IMQ compared to Wt mice. These results are important for further understanding how the circadian clock regulates immune activation in response to the theraputic agent IMQ.

Description
Boar taint (BT) is an offensive odour or taste observed in pork from a proportion of non-castrated male pigs. Surgical castration is effective in avoiding BT, but animal welfare issues have created an incentive for alternatives such as genomic selection. In order to find candidate biomarkers, gene expression profiles were analysed from tissues of non-castrated pigs grouped by their genetic merit of BT. Differential expression analysis revealed substantial changes with log-transformed fold changes of liver and testis from -3.39 to 2.96 and -7.51 to 3.53, respectively. Co-expression network analysis revealed one module with a correlation of -0.27 in liver and three modules with correlations of 0.31, -0.44 and -0.49 in testis. Differential expression and co-expression analysis revealed candidate biomarkers with varying biological functions: phase I (COQ3, COX6C, CYP2J2, CYP2B6, ACOX2) and phase II metabolism (GSTO1, GSR, FMO3) of skatole and androstenone in liver to steroidgenesis (HSD17B7, HSD17B8, CYP27A1), regulation of steroidgenesis (STARD10, CYB5R3) and GnRH signalling (MAPK3, MAP2K2, MAP3K2) in testis. Overrepresented pathways included “Ribosome”, “Protein export” and “Oxidative phosphorylation” in liver and “Steroid hormone biosynthesis” and “Gap junction” in testis. Future work should evaluate the biomarkers in large populations to ensure their usefulness in genomic selection programs. Overall design: Total RNA was extracted from liver and testis of 48 Danish Landrace pigs with low- medium and high genetic merit of boar taint and sequenced by Illumina HiSeq 2500.

Description
We hypothesize that the observed differences in incidences of pleural and peritoneal malignant mesothelioma (MM) are the result of differences in the direct response of these cell types to asbestos rather than to differences mediated by the in vivo microenvironment. To test this hypothesis, we characterized cellular responses to asbestos in a controlled environment using high-throughput RNA sequence and other assays. Overall design: Examination of asbestos-treated versus untreated mesothelial cells from four cell lines representing two tissue types in culture.
