Description
Background: With less than a 5% survival rate pancreatic adenocarcinoma (PDAC) is almost uniformly lethal. In order to make a significant impact on survival of patients with this malignancy, it is necessary to diagnose the disease early, when curative surgery is still possible. Detailed knowledge of the natural history of the disease and molecular events leading to its progression is therefore critical.

- Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
Tissue-resident mononuclear phagocytes (MNPs) in metabolic organs contribute to the regulation of whole body metabolism. CD301b+ MNPs are a subset of MNPs that are found in most peripheral organs including metabolic organs. In a mouse model in which CD301b+ MNPs can be selectively and transiently depleted, we examined the impact of the depletion on gene expression in the white adipose tissue and the liver.

Description
Microglia have emerged as crucial players in the maintenance of mechanical hypersensitivity in models of chronic pain, including rheumatoid arthritis. Recent studies have suggested that there is a sexually dimorphic microglial involvement in chronic pain, but the debate is still ongoing. Here, we have used the collagen antibody-induced arthritis (CAIA) mouse model to ascertain possible differences between male and female microglia in the context of arthritis-induced pain. We have focused on the late phase of this arthritis model, when joint inflammation has resolved but mechanical hypersensitivity and microglial activation persist. We found that intrathecal administration of minocycline reversed mechanical thresholds to control levels in male, but not female mice. Moreover, we isolated resident microglia from the lumbar dorsal horns of male and female mice and observed a significantly lower number of microglial cells in females by flow cytometry analysis. Furthermore, genome-wide RNA sequencing results pointed to several transcriptional differences between male and female microglia, but no convincing differences were identified between control and CAIA groups. Taken together, these findings suggest that there are significant but subtle sex differences in microglial expression profiles independent of treatment. To what extent they help bring about the behavioural sexual dimorphism observed after minocycline administration remains to be explored. Finally, our experiments failed to identify the underlying biological correlates of the microglial activation that is present in the late phase of the CAIA model. It is likely that transcriptional changes are either subtle and highly localised and therefore difficult to identify with bulk isolation techniques or that other factors, such as changes in protein expression or epigenetic modifications are at play. Overall design: RNA-seq of male and female saline or CAIA treated mice

Description
We investigated the differential regulation patterns of type I anti-CD20 monoclonal antibody (mAb) rituximab and type II obinutuzumab on a transcriptional level. Using a panel of MCL cell lines, we determined the effects of obinutuzumab and rituximab as monotherapies as well as in combination on cell viability and proliferation.

Description
To validate the suitability of two commonly used colorectal cancer cell lines, DLD1 and SW480, as model systems to study colorectal carcinogenesis, we treated these cell lines with -catenin siRNA and identified -catenin target genes using DNA microarrays. The list of identified target genes was compared to previously published -catenin target genes found in the PubMed and the GEO databases.

Description
The goals of this study were to determine global differences in transcript expression and regulation between MM cells that are sensitive or insensitive to lovastatin-induced apoptosis. To this end, two sensitive (KMS11 and H929) and two insensitive (LP1 and SKMM1) MM cell lines treated with 20uM lovastatin or an ethanol vehicle control for 16 hours. mRNA was extracted and prepared for mRNA expression microarrays (HG-U133 Plus 2) in triplicate.
