Affymetrix Rhesus Macaque Genome Array (rhesus)
Description
Graft versus host disease (GVHD) is the most common complication of hematopoietic stem cell transplant (HCT). However, our understanding of the molecular pathways that cause this disease remains incomplete, leading to inadequate treatment strategies. To address this, we measured the gene expression profile of non-human primate (NHP) T cells during acute GVHD. In this study we specifically interrogated the transcriptional signatures of animals treated with FR104 monotherapy and FR104/Sirolimus combination therapy

Description
MyD88-independent signal transduction associated with Toll-like receptors (TLRs) 3 and TLR4 is mediated through the adapter protein TRIF (TIR-domain-containing adapter-inducing interferon-beta). It has been proposed that TLR signalling is important for the transcription of crucial inflammasome components like NLRP3, a process that has been termed "priming". In order to test whether TRIF signalling was required for the priming of inflammasome components, we performed a genome wide transcriptional analysis on wild-type and Trif-knockout bone marrow derived macrophages (BMMs) before and 1, 3 and 6 hours after phagocytosis of E. coli. These results indicated that TRIF was involved in the activation and not transcriptional priming of the NLRP3 inflammasome.

Description
Recognition and removal of apoptotic cells by professional phagocytes, including dendritic cells and macrophages, preserve self-tolerance and prevent chronic inflammation and autoimmune pathologies. However the diverse array of phagocytes residing within different tissues combined with the necessarily prompt nature of apoptotic cell clearance has made it difficult to study this process in situ. Thus, the full spectrum of functions executed by tissue resident phagocytes in response to homeostatic apoptosis remains unclear.

Different tissue phagocytes sample apoptotic cells to direct distinct homeostasis programs.

Description
Background: Mycobacterium tuberculosis infection is a leading cause of infectious death worldwide. Gene-expression microarray studies profiling the blood transcriptional response of tuberculosis (TB) patients have been undertaken in order to better understand the host immune response as well as to identify potential biomarkers of disease. To date most of these studies have focused on pulmonary TB patients with gene-expression profiles of extra-pulmonary TB patients yet to be compared to those of patients with pulmonary TB or sarcoidosis.

Description
PKCe, an oncogenic member of the PKC family, is aberrantly overexpressed in epithelial cancers. To date, little is known about functional interactions of PKCe with other genetic alterations and the effectors of this kinase that contribute to its tumorigenic and metastatic phenotype. Here we demonstrate that PKCe cooperates with the loss of the tumor suppressor Pten for the development of prostate cancer in a mouse model. Mechanistic analysis revealed that PKCe overexpression and Pten loss individually and synergically cause a remarkable up-regulation in the production of the chemokine CXCL13. Notably, targeted disruption of CXCL13 or its receptor CXCR5 in prostate cancer cells impaired their migratory and tumorigenic properties. In addition to providing evidence for an autonomous vicious cycle driven by PKCe, our studies identified a compelling rationale for targeting the CXCL13:CXCR5 axis for prostate cancer treatment.

Description
While recent clinical studies demonstrate the promise of cancer immunotherapy, a barrier for broadening the clinical benefit is identifying how tumors locally suppress cytotoxic immunity. As an emerging mode of intercellular communication, exosomes secreted by malignant cells can deliver a complex payload of coding and non-coding RNA to cells within the tumor microenvironment. Here, we quantified the RNA payload within tumor-derived exosomes and the resulting dynamic transcriptomic response to cytotoxic T cells upon exosome delivery to better understand how tumor-derived exosomes can alter immune cell function. Exosomes derived from B16F0 melanoma cells were enriched for a subset of coding and non-coding RNAs that did not reflect the abundance in the parental cell. Upon exosome delivery, RNAseq revealed the dynamic changes in the transcriptome of CTLL2 cytotoxic T cells. In analyzing transiently co-expressed gene clusters, pathway enrichment suggested that the B16F0 exosomal payload altered mitochondrial respiration, which was confirmed independently, and upregulated genes associated with the Notch signaling pathway. Interestingly, exosomal miRNA appeared to have no systematic effect on downregulating target mRNA levels. Overall design: CTLL2 cells were grown in complete media for 24 hrs, and then stimulated with fresh B16F0 exosomes resuspended in PBS, to a final exosome concentration of 0.2 mg/ml. The transcriptome of untreated CTLL2 cells was assayed at 0, 0.5, 2, 4, and 8 hours after cells were placed in fresh media. There are 4 biological replicates at the 0 hour time point and 3 biological replicates at the 0.5, 2, 4, and 8 hour time points. The transcriptome of CTLL2 cells treated with B16F0 exosomes was assayed at 0.5, 2, 4, and 8 hours after addition of fresh media containing B16F0 exosomes. There were 3 biological replicates performed at each time point.

Description
Treatment of leukemia cells with 1,25-dihydroxyvitamin D3 may overcome their differentiation block and lead to the transition from myeloblasts to monocytes. To identify microRNA-mRNA networks relevant for myeloid differentiation, we profiled the expression of mRNAs and microRNAs associated to the low- and high-density ribosomal fractions in leukemic cells and in their differentiated monocytic counterpart. Intersection between mRNAs shifted across the fractions after treatment with putative target genes of modulated microRNAs showed a series of molecular networks relevant for the monocyte cell fate determination
