Development and validation of an ELISA to measure REG3E in canine blood

ABSTRACT: Regenerating islet-derived proteins (REG) are upregulated in people with sepsis, pancreatitis, and gastrointestinal diseases. One member of the REG family, namely REG3E, was recently identified in pancreatic tissue and plasma of dogs, with high expression in pancreatitis and sepsis. Our objective was to develop and validate an ELISA to measure REG3E concentrations in canine blood. An indirect sandwich ELISA was successfully developed using recombinant canine REG3E protein and polyclonal anti-canine REG3E antibodies raised in guinea pigs and rabbits. Antibody specificity was assessed using Western blot and mass spectrometric analysis of protein purified from canine plasma using Protein A Sepharose High Performance SpinTrap columns.

ANKRD31 protein interactions

Project description:Sex chromosomes in males of most mammalian species share only a small homologous segment, the pseudoautosomal region (PAR), wherein double-strand break (DSB) formation must occur for correct meiotic segregation. We find that multiple DSB-promoting factors hyperaccumulate in the PAR, including the ankyrin-repeat domain-containing protein ANKRD31. We used immunoprecipitation and mass spectrometry from extracts of juvenile mouse testes to identify potential ANKRD31-interacting proteins.

Identification of regenerating island-derived protein 3E in dogs

Project description:Our aim was to identify Regenerating islet-derived (REG proteins in dogs. We annotated REG-family members in the canine genome and proteome, and identified one member of the REG3 subfamily, consequently termed REG3E by the Vertebrate Gene Nomenclature Committee. We verified REG3E gene expression using publicly available RNA-seq data (www.barkbase.org). We investigated the presence of REG3E protein in canine pancreatic tissue and plasma with Western blot and immunohistochemistry, using anti-human REG3A antibodies. Protein identity was subsequently confirmed with mass spectrometry on canine pancreas homogenates and plasma.

Expression data from canine osteosarcoma stem cells

Project description:Osteosarcoma is the most common primary bone tumours of dogs. Canine osteosarcoma contains a sub-population of cancer stem cells. Here we used canine-specific microarrays to compare the global gene expression profiles of osteosarcoma stem cells to adherent cancer cells and canine mesenchymal stem cells. Canine osteosarcoma spheres were isolated by their ability to form tumourspheres. Spheres, adherent cells and mesenchymal stem cells were harvested and used for RNA extraction and hybridisation on Affymetrix microarrays (Canine 2.0). Four biological replicates of each sample were included.

Identification of Smaug target mRNAs in the early Drosophila embryo using RIP-Chip

Project description:To identify SmaugM-bM-^@M-^Ys target mRNAs on a genome-wide scale we used ribonucleoprotein (RNP) co-immunoprecipitation followed by microarray analysis of the co-purifying mRNAs (RIP-Chip). Extracts, prepared from wild-type embryos collected 0-3 hours post-egglaying, were immunoprecipitated with an anti-Smaug antibody (Smaug RIPs) while control immunoprecipitations using non-immune serum served as a negative control (control RIPs). Genome-wide transcript expression in wild-type embryos were also assessed and used as reference. There are 11 array experiments presented here: 1. gene expression profiling of total mRNA sample extracted from wild-type 0-3 hour embryos (3 technical replicates performed using a pooled input reference sample); 2. RNA co-immunoprecipitations of endogenous Smaug (Smaug RIPs) from wild-type 0-3 hour embryos (3 biological replicates and 1 technical replicates); 3. control RNA co-immunoprecipitations (control RIPs) from wild-type 0-3 hour embryos (3 biological replicates and 1 technical replicates).

H3N2 canine influenza virus causes severe clinical signs in dogs with induction of genes related to inflammation and apoptosis

Project description:We demonstrated canine influenza virus (H3N2) pathogenicity to dogs using microarray analysis. Many genes related to innate immunity, such as toll-like receptors, immune cells of natural killer cells, macrophages, neutrophils, nitric oxide and reactive oxygen species, and interferon, were induced. RNA was extracted from canine influenza virus H3N2-infected dogs. The lung RNA of uninfected dogs was used as a negative control. We compared gene expression levels between infected and uninfected dogs using microarray analysis.

Identification of Six Potential Markers for the Detection of Circulating Canine Mammary Tumor Cells in the Peripheral Blood

Project description:Circulating tumor cells in the peripheral have proven to be independent prognostic factors for overall survival the monitoring of therapeutic success of human breast cancer patients. Postmortem morphologic evidence also points towards the presence of circulating tumor cells in the peripheral blood of dogs with metastatic canine mammary tumors. However, the existence of these cells has not been verified in canines in vivo and they have not been isolated and characterized due to the lack of appropriate and canine specific detection methods. In the present study a panel of 73 genes with high expression levels in canine mammary carcinoma cells and but not in peripheral blood leukocytes were identified using microarray analysis. From this panel, six mRNA markers, AGR2, ATP8B1, CRYAB, F3 and IRX3, were expressed in canine mammary carcinoma cells but not in the peripheral blood of dogs. All six RT-PCR assays, were sensitive enough detect one carcinoma cell admixed in 106 or more peripheral blood leukocytes, a common concentration of circulating tumor cells in the peripheral blood of human breast cancer patients. These five mRNA markers may therefore be used to detect canine mammary circulating tumor cells and to study their spatio-temporal presence in the peripheral blood of canine patients. Two canine mammary carcinoma cell lines, CMM115 and CMM26, and peripheral blood samples of 3 healthy dog donors were used for microarray analysis. All blood donors were female, showed no signs of infectious or inflammatory disease and did not have mammary gland tumors or any other identifiable tumors at the time of collection. Furthermore, blood cell count and blood chemistry were unremarkable in all dogs.
