Proteolytic Release Of Cd44 Intracellular Domain And Its Role In The Cd44 Signaling Pathway., I Okamoto, Y Kawano, D Murakami, T Sasayama, N Araki, T Miki, A J Wong, H Saya

Department of Microbiology and Immunology Faculty Papers

CD44 is a widely distributed cell surface adhesion molecule and is implicated in diverse biological processes. However, the nature of intracellular signaling triggered by CD44 remains to be elucidated. Here, we show that CD44 undergoes sequential proteolytic cleavage in the ectodomain and intracellular domain, resulting in the release of a CD44 intracellular domain (ICD) fragment. Consequently, CD44ICD acts as a signal transduction molecule, where it translocates to the nucleus and activates transcription mediated through the 12-O-tetradecanoylphorbol 13-acetate-responsive element, which is found in numerous genes involved in diverse cellular processes. Expression of an uncleavable CD44 mutant as well as metalloprotease inhibitor …

The Girl Who Cried Pain: A Bias Against Women In The Treatment Of Pain, Diane E. Hoffmann, Anita J. Tarzian

Faculty Scholarship

In general, women report more severe levels of pain, more frequent incidences of pain, and pain of longer duration than men, but are nonetheless treated for pain less aggressively. The authors investigate this paradox from two perspectives: Do men and women in fact experience pain differently - whether biologically, cognitively, and/or emotionally? And regardless of the answer, what accounts for the differences in the pain treatment they receive, and what can we do to correct this situation?

Technology Evaluation: Pro-542, Progenics Pharmaceuticals Inc., Muhammad Mukhtar, Zahida Parveen, Roger J Pomerantz

A further grant of $2.7 million was awarded in August 1998 for the clinical evaluation of PRO-542 and other anti-HIV therapies [294200]. Progenics is collaborating with the …

Genetic Control Of Eye Development, A Case Study Focused On The Murine Mutation Belly Spot And Tail (Bst), Qing Tang

Theses and Dissertations (ETD)

Development of the eye is controlled by a network of genes, often conserved, that regulate the timing and location of cellular differentiation. One approach to understanding this network of genes and their interaction is to focus on mutations, spontaneous or induced, that predictably disrupt the proper function of such networks, and by examining the effect of such disruption on the function of other genes.

The Belly spot and tail (Bst) semi-dominant mutation, mapped to mouse Chromosome 16, leads to developmental defects of the eye, skeleton, and coat pigmentation. In the eye, the mutant phenotype is characterized by the presence of …

Potential Associations Among Genetic Markers In The Serotonergic System And The Antisocial Alcoholism Subtype, E. M. Hill, S. F. Stoltenberg, M. Burmeister, M. Closser, R. A. Zucker

Department of Psychology: Faculty Publications

Alcoholism is transmitted in families. The complexity and heterogeneity of this disorder has made it difficult to identify specific genetic correlates. One design with the potential to do so is the family-based association study, in which the frequencies of genetic polymorphisms are compared between affected and nonaffected members. Reduced central serotonin neurotransmission is associated with features of an antisocial subtype of alcoholism, although a primary deficit has not been traced to a particular component. Genetic markers related to the serotonergic system have been identified, located, and cloned. If associations can be discovered, the development process for pharmacotherapy could be facilitated. …

Neurology Collection

While functional magnetic resonance imaging (fMRI) is now used widely for demonstrating neural activity-related signals associated with perceptual, motor, and cognitive processes in humans, to date this technique has not been developed for use with nonhuman primates. fMRI in monkeys offers a potentially valuable experimental approach for investigating brain function, which will complement and aid existing techniques such as electrophysiology and the behavioral analysis of the effects of brain lesions. There are, however, a number of significant technical challenges involved in using fMRI with monkeys. Here, we describe the procedures by which we have overcome these challenges to …

Developmental And Hormonal Regulation Of The Expression Of Cytosolic Phospholipase A2 Protein Levels In Baboon Placenta, Kathleen Elizabeth Dunstan

Chemistry & Biochemistry Theses & Dissertations

Cytosolic phospholipase A₂ ( cPLA₂) specifically catalyzes the release of arachidonate from membrane phospholipids, thus initiating synthesis of prostaglandins, thromboxanes, and other eicosanoids. The human and nonhuman primate placenta actively synthesize high levels of eicosanoids which play both an autocrine and paracrine role in placental function. Previous studies in Dr. Miriam D. Rosenthal's laboratory have shown that cPLA₂ mRNA levels are developmentally regulated. The present study was designed to determine whether placental cPLA₂ protein levels increased during gestation. Since the marked increases in estrogen levels during normal pregnancy have been shown to enhance morphological and …

Mummies And Mummification Practices In The Southern And Southwestern United States, Mahmoud Y. El-Najjar, Thomas M. J. Mulinski, Karl Reinhard

Karl Reinhard Publications

Mummification was not intentional for most North American prehistoric cultures. Natural mummification occurred in the dry areas of North America, where mummies have been recovered from rock shelters, caves, and overhangs. In these places, corpses desiccated and spontaneously mummified. In North America, mummies are recovered from four main regions: the southern and southwestern United States, the Aleutian Islands, and the Ozark Mountains of Arkansas. This chapter is limited to a discussion of burial practices and a tabulation of the location of mummies in the southwestern United States with some comments on mummies of the southern United States, including the Ozarks.

The Relationship Between Meaning In Life And The Occurrence Of Drug Abuse: An Epidemiological Retrospective Study, Ben Howard

Masters Theses & Specialist Projects

Humans have been using plant-derived drugs for as long as we have recorded history. Significant negative consequences related to drug abuse have occurred in the areas of health, social issues, family relations, legal systems, and economic productivity. The purpose of this study was to explore the relationship between meaning in life and drug abuse. An epidemiological, retrospective study was performed to compare personal meaning in life between individuals receiving inpatient treatment for drug abuse and a group of non-drug abusing controls. Study participants completed the Purpose-In-Life Test and Life Attitude Profile-Revised. On both instruments, the inpatient drug abusing subjects were …

The Relationship Between The Fibrinogen D Domain Self-Association/Cross-Linking Site (Gammaxl) And The Fibrinogen Dusart Abnormality (Aalpha R554c-Albumin): Clues To Thrombophilia In The "Dusart Syndrome", Michael W. Mosesson, Kevin R. Siebenlist, James F. Hainfeld, J. S. Wall, C. Soria, J. P. Caen

Biomedical Sciences Faculty Research and Publications

Cross-linking of fibrinogen at its COOH-terminal gamma chain cross-linking site occurs in the presence of factor XIIIa due to self-association at a constitutive D domain site ("gammaXL"). We investigated the contribution of COOH-terminal regions of fibrinogen Aalpha chains to the gammaXL site by comparing the gamma chain cross-linking rate of intact fibrinogen (fraction I-2) with that of plasma fraction I-9, plasmic fraction I-9D, and plasmic fragment D1, which lack COOH-terminal Aalpha chain regions comprising approximately 100, approximately 390, and 413 residues, respectively. The cross-linking rates were I-2 > I-9 > 1-9D = D1, and indicated that the terminal 100 or more Aalpha …

Evidence For A Second Type Of Fibril Branch Point In Fibrin Polymer Networks, The Trimolecular Junction, Michael W. Mosesson, James P. Diorio, Kevin R. Siebenlist, Joseph S. Wall, James F. Hainfeld

Biomedical Sciences Faculty Research and Publications

Fibrin molecules polymerize to double-stranded fibrils by intermolecular end-to-middle domain pairing of complementary polymerization sites, accompanied by fibril branching to form a clot network. Mass/length measurements on scanning transmission electron microscopic images of fibrils comprising branch points showed two types of junctions. Tetramolecular junctions occur when two fibrils converge, creating a third branch with twice the mass/length of its constituents. Newly recognized trimolecular junctions have three fibril branches of equal mass/length, and occur when an extraneous fibrin molecule initiates branching in a propagating fibril by bridging across two unpaired complementary polymerization sites. When trimolecular junctions predominate, clots exhibit nearly perfect …

The Isolation And Identification Of Polyphenolics From Grape Seeds And Their Activity Towards Specific Cell Lines, Joseph A. Reddy

Chemistry & Biochemistry Theses & Dissertations

Grape seed extract is being marketed in France for cardiovascular use and skin care. The active constituents of both these drugs are certain polyphenols called procyanidins. A similar seed extract has now been obtained from Virginia Chardonnay grape seeds. Ten of the major components in this extract have been isolated in their pure form by the semi-preparative HPLC separation on a YMC ODS-AQ (Octadecylsilane-AQ) column. The ODS-Aq column has been shown to have a better resolving capacity compared to the Spherisorb ODS (Octadecylsilane) column previously described in the literature. This has been attributed to the ODSAQ support which has both …

Proto-Oncogenes Of Genomic Dna In Normal Thai Domestic Animal, Achariya Sailasuta, Ted Tesaprateep, Boonmee Sunyasootcharee, Susumu Tateyama, Ryoji Yamaguchi, Dai Nosaka, Noriaki Miyoshi

The Thai Journal of Veterinary Medicine

The proto-oncogenes homologous to the c-myc, c-ros-1, c-yes-1, and v-Ki-ras oncogenes of genomic DNAs in buffaloes, dogs, cats and ducks were investigated with Southern blot hybridization. High molecular-weight-genomic DNAs in each of the animals animals contained proto-oncogenes showing more than 65% homology of the proto-oncogenes differed in both number and approximate molecular weight: i.e. one or two bands at 1.6 to 18.0 kilobase (kb) in the c-myc probe, one band at 1.1 to 15.0 kb in the c-ros-1 probe, one to five bands at 0.3 to 18.0 kb in the c-yes-1 probe, and one to five bands at 1.6 to …

Molecular Genetic Mapping Of The Multiple Endocrine Neoplasia Type 1 Locus, Joanna T. Pang, Mark A. Pook, James H. Eubanks, Carol Jones, Veronica Van Heyningen, Glen A. Evans, Rajesh V. Thakker

Henry Ford Hospital Medical Journal

Familial multiple endocrine neoplasia type 1 (MEN 1) is an autosomal dominant disorder characterized by the combined occurrence of tumors of the parathyroid glands, the endocrine pancreas, and the pituitary gland. MEN 1 tumors have previously been shown to be associated with the loss of alleles on chromosome 11, and deletion mapping studies together with family linkage studies have localized the MEN 1 gene to 11q13. A detailed genetic map around the MEN 1 locus is required to facilitate further characterization and cloning of the gene (MEN1). We have characterized a panel of seven rodent-human somatic cell hybrids which contain …

Coprolite Analysis: A Biological Perspective On Archaeology, Karl J. Reinhard, Baughn M. Bryant Jr

Karl Reinhard Publications

The most remarkable dietary remains recoverable from archaeological contexts are coprolites. Coprolites are desiccated or mineralized feces that are preserved in sheltered and open sites in arid regions, primarily in the New World. These dietary remains are remarkable from several perspectives. They typically contain a variety of macroscopic and microscopic remains that form interrelated data sets for the reconstruction of diets. Because contexts containing coprolites are typified by excellent preservation, the remains coprolites contain tend to be in better states of preservation than dietary remains recovered from nonfecal deposits. Coprolites also contain the well-preserved remains of intestinal parasites and pathogens …

Nursing Care Of The Elderly In The Acute Care Setting: An Investigation Of Powerlessness, Dorothy De Boer Zylstra

Masters Theses

This study's purpose was to identify whether persons 65 years of age or older hospitalized with congestive heart failure perceive personal powerlessness. Cognitive competence of the subjects was determined by the Short Portable Mental Status Questionnaire. A Powerlessness Interview Schedule (PIVS) was used to identify subjects' perceptions of personal powerlessness.; Perceived powerlessness was not conclusively apparent in the fifty-one subjects of this study. No subjects received a score of 38 or below. Ten of fifty-one subjects received scores ranging from 46 to 56 which may place them at risk for perceived personal powerlessness. Forty-nine subjects had areas of limited feelings …

Proto-Oncogene Regulation By Growth Factors In Bone Cells, Harold Lyndon Merriman

Loma Linda University Electronic Theses, Dissertations & Projects

Previous studies have shown that bone cells in culture produce a number of growth factors that are important in bone regulation. Chick and mouse primary calvarial cultures consist of a mixture of cell types that make it difficult to interpret the results from these model systems. In contrast, MC3T3-E1 cells are a clonal mouse osteoblast-like cell line. Since MC3T3-E1 cells consist of a single population of calvarial cells, they make an ideal system in which to study the autocrine effects of bone growth factors.

Based on this work, MC3T3-E1 cells are now known to produce IGF-I, TGF-beta and IGF-II in …

Embryonic Chicken Fibroblast Collagen Binding Proteins: Distribution, Role In Substratum Adhesion, And Relationship To Integrins, Roy C. Ogle, A. Jeannette Potts, Marchall Yacoe, Charles D. Little

School of Medical Diagnostics & Translational Sciences Publications

Collagen binding proteins (CBP) are hydrophobic, cell surface polypeptides, isolated by collagen affinity chromatography. Antibodies to CBPs inhibit the attachment of embryonic chicken heart fibroblasts to native type I collagen fibrils in a dose-dependent manner. The CBP antibodies also induce rounding and detachment of cells adherent to a planar substratum. This process of antibody-mediated substratum detachment resulted in a clustering of CBP and cell-associated extracellular matrix at the cell surface, and the rearrangement of filamentous actin. Other functional studies showed that cells grown within a three-dimensional gel of type I collagen cannot be immunostained at the cell surface with CBP …
