Title: Tissues from the irradiated dog/mouse archive

Abstract

The purpose of this project is to organize the databases/information and organize and move the tissues from the long-term dog (4,000 dogs) and mouse (over 30,000 mice) radiation experiments done at Argonne National Laboratory during the 1970's and 80's to Northwestern University. These studies were done with the intention of understanding the effects of exposure to radiation at a variety of different doses, dose-rates, and radiation qualities on end-points such as life-shortening, carcinogenesis, cause of death, shifts in disease incidence and other biological parameters. Organ and tissue samples from these animals including cancers, metastases and other significant degenerative and inflammatory lesions and those in a regular protocol of normal tissues were preserved in paraffin blocks, tissue impressions and sections and represent a great resource for the radiation biology community. These collections are particularly significant since these experiments are not likely to be repeated because of the extreme cost of monies and time for such large-scale animal studies. The long-term goal is to make these tissues and databases available to the wider scientific community so that questions such as tissue sensitivity, early and late effects, low dose and protracted dose responses of normal and tumor tissues, etc. can be examined andmore » defined. Recent advances in biology particularly at the subcellular and molecular level now permit microarray-based gene expression array analyses from paraffin-embedded tissues (where RNA samples are significantly degraded), synchrotron-based studies of metal and other elemental distribution patterns in tissues, PCR-based analyses for mutation detection, and other similar approaches that were not available when the long¬ term animal studies were designed and initiated. Understanding the basis and progression of radiation damage should also permit rational approaches to prevention and mitigation of those damages. Therefore, as stated earlier, these tissues and their related documentation, represent a significant resource for future studies. For this project, we propose to accomplish the following objectives: (1) inventory and organize the tissues, blood smears, wet-tissues and paper-¬based information that is available in the tissue bank at Argonne National Laboratory; (2) convert the existing Oracle database of the mouse studies to MS Access( the dog data is already in this format which is far more user friendly and widely used in business and research) , (3) move the remaining samples and documentation from dogs that had been transferred from ANL to New Mexico (in Dr. F. Hahn's care) to Northwestern University and add these to the inventory; (4) move the tissues and Access database at Argonne National Laboratory to Northwestern University.« less

  • Test data on desensitization anaphylotis in guinea pigs showed decreased antigen complexes in gamma -globulin from perfuse tissues from irradiated dogs. Immunization of healthy dogs by homologous gamma -globulin from irradiated dog perfuse tissues also indicated antigenic changes. (R.V.J.)
  • The pancreatic islets of Langerhans and insulin-producing beta cells in particular play a central role in the maintenance of glucose homeostasis and the islet dysfunction is associated with the pathogenesis of both type 1 and type 2 diabetes mellitus. To contribute to the understanding of the biology of the pancreatic islets we applied proteomic techniques based on liquid chromatography coupled with mass spectrometry. Here as an initial step we present the first comprehensive proteomic characterization of pancreas islets of the mouse, the commonly used animal model for diabetes research. Two-dimensional SCX LC/RP LC-MS/MS has been applied to characterize of themore » mouse islet proteome, resulting in the confident identification of 17,350 different tryptic peptides covering 2,612 proteins with at least two unique peptide identifications per protein. The dataset also allowed identification of a number of post-translational modifications including several modifications relevant to oxidative stress and phosphorylation. While many of the identified phosphorylation sites corroborates with previous known sites, the oxidative modifications observed on cysteinyl residues potentially reveal novel information related to the role of oxidation stress in islet functions. Comparative analysis of the islet proteome database with 15 available proteomic datasets from other mouse tissues and cells revealed a set of 68 proteins uniquely detected only in the pancreatic islets. Besides proteins with known functions, like islet secreted peptide hormones, this unique set contains a number of proteins with yet unknown functions. The resulting peptide and protein database will be available at ncrr.pnl.gov web site of the NCRR proteomic center (ncrr.pnl.gov).« less
  • Hydrogen isotopes are fractionated during biochemical reactions in a variety of organisms. A number of experiments have shown that the D/H ratios of animals and their tissues are not controlled solely by the D/H ratios of their food. The authors performed a simple experiment which indicated that the D/H ratios of a significant fraction of the organically bonded hydrogen in animal tissues must be determined by the isotopic composition of water that the samples encounter. Aliquots of dried mouse brain and liver and mouse food were exposed to water vapors of different D/H ratios prior to isotopic analysis. The resultsmore » of the experiment showed that at least 16 percent of the hydrogen in mouse brain is exchangeable with the hydrogen of water; the corresponding values for mouse liver and mouse food were 25 to 29 percent.
