The pH-sensing receptor ovarian cancer G protein-coupled receptor 1 (OGR1; GPR68) is expressed in the gut. Inflammatory bowel disease is typically associated with a decrease in local pH, which may lead to altered epithelial barrier function and subsequent gastrointestinal repair involving epithelial cell adhesion and migration. As the mechanisms underlying the response to pH changes are not well understood, we have investigated OGR1-mediated, pH-dependent signaling pathways in intestinal epithel ...[more]

The G protein-coupled pH-sensing receptor OGR1 is a regulator of intestinal inflammation

Project description:OGR1 is a pH sensing G protein-coupled receptor involved in intestinal homeostasis and inflammation. Up-regulation of genes, mediated by OGR1, in response to extracellular acidification were enriched for inflammation, immune response, actin cytoskeleton and cell adhesion pathways. Microarray profiling was performed to compare global gene expression of Ogr1 KO and WT residential peritoneal macrophages in response to an acidic pH shift (pH 6.7, 24 h)

Microarray-based gene expression data from BPLER tumor explants.

Project description:The gene expression of 6 different mouse xenografts initiated by BPLER cells analyzed by microarray. Basal-like triple negative breast cancers (TNBC) have poor prognosis. To study the basal-like transcriptional profile of tumors transformed by defined genetic elements, the human breast epithelial cell line BPLER was injected into NOD/SCID mice. The resulting tumors were excised for expression analysis. Keywords: breast cancer, BPLER, metastasis, tumor stem cells, tumor initiating cells, breast adenocarcinoma BPLER cells were derived from human primary breast epithelial cells propagated in WIT medium (Ince et al, Cancer Cell, 2007). These cells were transformed with hTERT, SV40 early region and hRASV12 by retroviral transduction. BPLER have a TNBC-like phenotype in vitro and are highly enriched for tumor-initiating cells. To define the phenotype of BPLER-derived tumors in vivo, BPLER cells were injected in the mammary fat-pad of 6 NOD/SCID mice. Once tumors were palpable, mice were sacrificed and tumors excised. Total RNA was extracted using Trizol. The gene expression profile of each tumor was assessed by mRNA microarray analysis. Based on histology and principal component analysis of microarray data, BPLER tumors were remarkably similar to human primary TNBC encountered in the clinic (Petrocca et al, Cancer Cell, 2013).

PPARÎ³ controls alveolar macrophage identity [part1]

Project description:Tissue-resident macrophages comprise heterogeneous populations with unique functions and distinct gene expression signatures. While it has been established that they mostly originate from embryonic progenitors, the signals inducing a characteristic tissue-specific differentiation program remain unknown. Here we identify PPARÎ³ as the crucial transcription factor determining perinatal alveolar macrophage (AM) development and identity. Development of the fetal monocyte derived AM precursor was largely abrogated in CD11c-Cre/Ppargfl/fl mice. To reveal the underlying changes in gene expression, we performed microarray analysis of sorted WT and KO AM and pre-AM from 3 different timepoints. Part1: d2 and d11 sorts & array pre-AM FACS-sorted from lungs of d2 and mature AM from d11 PPARgfl/fl (WT) and CD11c-cre/PPARgfl/fl (KO) mice and subsequently processed for RNA extraction and hybridization on Affymetrix microarrays. 2 biological replicates per group, each composed of pooled cells from 2 individual mice

Comparison of acid treated and untreated

Project description:Enterohemorrhagic Escherichia coli (EHEC) is a gram negative enteric bacterial pathogen that can cause hemorrhagic colitis and heamolytic uremic syndrome (HUS) in humans and is the cause of bloody diarrhoea and acute renal failure in children. We have studied the transcriptional response of a colon cell line (CaCo2) to infection by EHEC and compared its profile to infection by EHEC shocked in acid at pH 2.5. We carried out microarray analysis on CaCo2 infected with EHEC O157H:7 EDL933 and EHEC shocked at pH 2.5 at 4 hours post infection.
