Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
RNA Pol II transcription has been implied to be either regulated by the general transcription factor TFIID or the co-activator SAGA. Also, this dominancy of either SAGA or TFIID might be according to the existance, or not, of a TATA consensus sequence.

Description
Many symptoms associated with allergic asthma result from the sequelae of type 2 inflammation. Interleukin (IL)-25 promotes type 2 inflammatory responses, and T2M cells represent an IL-4 and IL-13 producing granulocytic IL-25 responsive population.

Interleukin-25 induces type 2 cytokine production in a steroid-resistant interleukin-17RB+ myeloid population that exacerbates asthmatic pathology.

Description
In support of our manuscript investigating the roles of ILCs and T cells in the maintenance of gut hoemostasis, we have performed RNAseq on terminal illeum of mice lacking either all adaptive immune cells (RAG1 -/-), deficient in T cells (TCRalpha -/-), or deficient in T cells but co-housed with wild-type mice and RAG1 -/- mice. Overall design: Tissues from three mice per group were analysed, and the following comparisions were made: RAG1-/- vs. WT C57BL/6 and TCRa-/- co-housed vs TCRa-/- seperately housed. Differential expression genes were identified at 1% FDR using DESeq2.

Glucocorticoids are part of the therapeutic armamentarium of chronic lymphocytic leukemia where it has been suggested that cells with unmutated IGHV genes exhibit higher sensitivity. The mechanisms by which glucorticoids are active in CLL are not well elucidated.

Description
Primary human foreskin fibroblasts (HFF) were exposed to either salt stress (80mM KCl) or heat stress (44ºC). Newly transcribed RNA was labelled by adding 500µM 4-thiouridine (4sU) to the cell culture media for 1h. Total cellular RNA was isolated using Trizol. Newly transcribed RNA was purified following the protocol described in Raedle et al. JoVE 2013. Overall design: Newly transcribed RNA was labelled in one hour intervals during either salt or heat stress (prior to stress, 0-1h or 1-2h). All 4sU-RNA samples were sent for sequencing. Two independent biological replicates were analysed.

Description
Pancreatic ductal adenocarcinoma (PDA) is characterized by abundant desmoplasia and poor tissue perfusion. These features are proposed to limit access of therapies to neoplastic cells and blunt treatment efficacy. Indeed, several agents that target the PDA microenvironment promote chemotherapy delivery and improve anti-neoplastic responses in murine models of PDA. Here, we employed the FG-3019 monoclonal antibody directed against the pleiotropic matricellular signaling molecule connective tissue growth factor (CTGF/CCN2). FG-3019 treatment increased PDA cell killing and led to a dramatic tumor response without altering gemcitabine delivery. Microarray expression profiling revealed the down-regulation by FG-3019 of several anti-apoptotic transcripts, including the master regulator Xiap, down-regulation of which has been shown to sensitize PDA to gemcitabine. Decreases in XIAP protein by FG-3019 in the presence and absence of gemcitabine were confirmed by immunoblot, while increases in XIAP protein were seen in PDA cell lines treated with recombinant CTGF. Therefore, alterations in survival cues following targeting of tumor microenvironmental factors may play an important role in treatment responses in animal models and, by extension, PDA patients.

Description
DNA methylation is an epigenetic mark that silences transposable elements (TEs) and repeats. Whereas the establishment and maintenance of DNA methylation are relatively well understood, little is known on their dynamics and biological relevance in plant and animal innate immunity. Here, we show that some TEs are demethylated and transcriptionally reactivated during antibacterial defense in Arabidopsis. This effect is concomitant with the down-regulation of key transcriptional gene silencing factors as well as an active demethylation process. DNA demethylation restricts multiplication and vascular propagation of the bacterial pathogen Pseudomonas syringae in leaves and, accordingly, some immune-response genes, containing repeats in their promoters, are negatively regulated by DNA methylation. This study provides evidence that DNA demethylation is part of a plant-induced immune response, potentially acting to prime transcriptional activation of some defense genes linked to Tes/repeats. We have monitored the transcript changes in Arabidopsis plants treated with a flagellin-derived peptide. Overall design: DNA methylation is closely related to 24nt sRNAs. This is why we sequenced small RNA population in our study. 5-week-old Col-0 leaf samples (treated with either water or flg22 at 1 ?M concentration for 6 h) and deep sequenced by Fasteris (Geneva) on the Illumina HiSeq 2000 platform.
