(Submitter supplied) ID8-based ovarian tumors were developed for 3 weeks in wild type (WT, N=3) or conditional knockout mice selectively deleting XBP1 in CD11c positive cells (KO, N=3). Tumor-associated DCs were independently sorted via FACS and used for transcriptional profiling.

(Submitter supplied) Tumors evade immune control by creating hostile microenvironments that perturb T cell metabolism and effector function. However, it remains unclear how intratumoral T cells integrate and interpret metabolic stress signals. Here we report that ovarian cancer (OvCa), an aggressive malignancy refractory to standard treatments and current immunotherapies, induces Endoplasmic Reticulum (ER) stress and activation of the IRE1α-XBP1 arm of the Unfolded Protein Response (UPR)10,11 in T cells to control their mitochondrial respiration and anti-tumor function. more...

(Submitter supplied) During cancer progression, carcinoma cells encounter a variety of cytotoxic stresses such as hypoxia, nutrient deprivation, and low pH as a result of inadequate vascularization. To maintain survival and growth in the face of these physiologic stressors, a set of adaptive response pathways are induced. One adaptive pathway well studied in other contexts is the unfolded protein response (UPR), of which XBP1 is an important component. more...

(Submitter supplied) We report the application of ChIP-seq, which combines chromatin immunoprecipitation (ChIP) with massively parallel DNA sequencing, to map genome-wide XBP1 binding sites in different breast cancer cell lines. We showed that HIF1α motif was enriched in XBP1 binding sites in triple negative breast cancer (TNBC) cell lines, but not enriched in ER positive breast cancer cell line. We also demonstrated that different breast cancer cell lines of the same sub-type had similar XBP1 binding sites, whereas different breast cancer sub-types had majorly different XBP1 binding sites. more...

(Submitter supplied) Purpose: microRNA profiles were generated from NIH-3T3 cells control and thapsigargin treated, in duplicate. The goal of this study was to compare microRNA profiles of untreated and thapsigargin treated NIH-3T3 fibroblast cells. Methods: NIH-3T3 cells were grown to confluency and either untreated or treated with 500 nM thapsigargin in media for 24 hours. Cells were harvested with TriZol and RNA isolated according to manufacturers protocol Analysis Outline: Short reads in fastq format were assembled using BclToFastq.pl script from Illumina CASAVA 1.8.1 software pipeline.Read quality was examined using FastQC program (http://www.bioinformatics.bbsrc.ac.uk/projects/fastqc). more...

(Submitter supplied) Purpose: The goals of this study are to assess the transcriptional networks governed by the transcription factor XBP1 in lineage-uncommitted myeloid progenitors and in eosinophil-committed myeloid progenitors. Methods: mRNA profiles of FACS-purified granulocyte-macrophage progenitors (GMPs) from XBP1 flox/flox or XBP1 flox/flox Vav1-Cre mice were generated by sequencing, in biological triplicates, using an Illumina HiSeq2000 sequencer. more...

(Submitter supplied) Xbp1 is a major transcription factor in the unfolded protein response. To uncover its function in DCs we generated a conditional KO for Xbp1 in dendritic cells. We here compare the expression of mRNAs in two different splenic DC subpopulations, CD8a and CD11b DCs in both WT and KO mice.
