Reelin Induces A Radial Glial Phenotype In Human Neural Progenitor Cells By Activation Of Notch-I, Serene Keilani, Kiminobu Sugaya

Faculty Bibliography 2000s

Background: Reelin and Notch-I signaling pathways have been recently found to be necessary to induce the expression of brain lipid binding protein ( BLBP) and to promote the process extension and the maturation of the neuronal progenitors, the radial glial cells. In this study, we report the cross talk between these two pathways. Results: Both in vitro Reelin treatment and overexpression of Notch-I intracellular domain (NICD) induced BLBP expression and a radial glial phenotype in an immortalized human neural progenitor (HNP) cell line, isolated from the cortex of 14 weeks old fetus. Reelin treatment increased the level of NICD, indicating …

Numb Endocytic Adapter Proteins Regulate The Transport And Processing Of The Amyloid Precursor Protein In An Isoform-Dependent Manner - Implications For Alzheimer Disease Pathogenesis, George A. Kyriazis, Zelan Wei, Miriam Vandermey, Dong-Gyu Jo, Ouyang Xin, Mark P. Mattson, Sic L. Chan

Faculty Bibliography 2000s

Central to the pathogenesis of Alzheimer disease is the aberrant processing of the amyloid precursor protein (APP) to generate amyloid beta-peptide (A beta), the principle component of amyloid plaques. The cell fate determinant Numb is a phosphotyrosine binding domain (PTB)-containing endocytic adapter protein that interacts with the carboxyl-terminal domain of APP. The physio-logical relevance of this interaction is unknown. Mammals produce four alternatively spliced variants of Numb that differ in the length of their PTB and proline-rich region. In the current study, we determined the influence of the four human Numb isoforms on the intracellular trafficking and processing of APP. …

Mcnay, Tingxi Yu, Robert Schwarzenbacher, Bliase Bossy, Ella Bossy-Wetzel, Michael V. L. Bennett, Marc Pypaert, John A. Hickman, Peter J. S. Smith, Marie Hardwick, Elizabeth A. Jones

Faculty Bibliography 2000s

Maturation of neuronal synapses is thought to involve mitochondria. Bcl-X-L protein inhibits mitochondria-mediated apoptosis but may have other functions in healthy adult neurons in which Bcl-X-L is abundant. Here, we report that overexpression of Bcl-X-L postsynaptically increases frequency and amplitude of spontaneous miniature synaptic currents in rat hippocampal neurons in culture. Bcl-X-L, overexpressed either pre or postsynaptically, increases synapse number, the number and size of synaptic vesicle clusters, and mitochondrial localization to vesicle clusters and synapses, likely accounting for the changes in miniature synaptic currents. Conversely, knockdown of Bcl-X-L or inhibiting. it with ABT-737 decreases these morphological parameters. The mitochondrial …

Genome-Wide Survey And Expression Profiling Of Ccch-Zinc Finger Family Reveals A Functional Module In Macrophage Activation, Jian Liang, Wenjun Song, Gail Tromp, Pappachan E. Kolattukudy, Mingui Fu

Faculty Bibliography 2000s

Previously, we have identified a novel CCCH zinc finger protein family as negative regulators of macrophage activation. To gain an overall insight into the entire CCCH zinc finger gene family and to evaluate their potential role in macrophage activation, here we performed a genome-wide survey of CCCH zinc finger genes in mouse and human. Totally 58 CCCH zinc finger genes in mouse and 55 in human were identified and most of them have not been reported previously. Phylogenetic analysis revealed that the mouse CCCH family was divided into 6 groups. Meanwhile, we employed quantitative real-time PCR to profile their tissue …

A Novel Ccch-Zinc Finger Protein Family Regulates Proinflammatory Activation Of Macrophages, Jian Liang, Jing Wang, Asim Azfer, Wenjun Song, Gail Tromp, Pappachan E. Kolattukudy, Mingui Fu

Faculty Bibliography 2000s

Activated macrophages play an important role in many inflammatory diseases. However, the molecular mechanisms controlling macrophage activation are not completely understood. Here we report that a novel CCCH-zinc finger protein family, MCPIP1, 2, 3, and 4, encoded by four genes, Zc3h12a, Zc3h12b, Zc3h12c, and Zc3h12d, respectively, regulates macrophage activation. Northern blot analysis revealed that the expression of MCPIP1 and MCPIP3 was highly induced in macrophages in response to treatment with lipopolysaccharide (LPS). Although not affecting cell surface marker expression and phagocytotic function, overexpression of MCPIP1 significantly blunted LPS-induced inflammatory cytokine and NO(2)radical anion. production as well as their gene expression. …

Experimentally, ZVIN of this study was prepared by sodium borohydride reduction method at room temperature and ambient pressure. The morphology of as-synthesized ZVIN shows that the nearly …


Revisiting The Mechanism Of Macrolide-Antibiotic Resistance Mediated By Ribosomal Protein L22, Sean D. Moore, Robert T. Sauer Jan 2008

Revisiting The Mechanism Of Macrolide-Antibiotic Resistance Mediated By Ribosomal Protein L22, Sean D. Moore, Robert T. Sauer

Faculty Bibliography 2000s

Bacterial antibiotic resistance can occur by many mechanisms. An intriguing class of mutants is resistant to macrolide antibiotics even though these drugs still bind to their targets. For example, a 3-residue deletion (Delta MKR) in ribosomal protein L22 distorts a loop that forms a constriction in the ribosome exit tunnel, apparently allowing nascent-chain egress and translation in the presence of bound macrolides. Here, however, we demonstrate that Delta MKR and wild-type ribosomes show comparable macrolide sensitivity in vitro. In Escherichia coli, we find that this mutation reduces antibiotic occupancy of the target site on ribosomes in a manner largely dependent …


Therapeutic Modulation Of Apoptosis: Targeting The Bcl-2 Family At The Interface Of The Mitochondrial Membrane, Kathleen N. Nemee, Annette R. Khaled Jan 2008

Therapeutic Modulation Of Apoptosis: Targeting The Bcl-2 Family At The Interface Of The Mitochondrial Membrane, Kathleen N. Nemee, Annette R. Khaled

Faculty Bibliography 2000s

A vast portion of human disease results when the process of apoptosis is defective. Disorders resulting from inappropriate cell death range from autoimmune and neurodegenerative conditions to heart disease. Conversely, prevention of apoptosis is the hallmark of cancer and confounds the efficacy of cancer therapeutics. In the search for optimal targets that would enable the control of apoptosis, members of the BCL-2 family of anti- and pro-apoptotic factors have figured prominently. Development of BCL-2 antisense approaches, small molecules, and BH3 peptidomimetics has met with both success and failure. Success-because BCL-2 proteins play essential roles in apoptosis. Failure-because single targets for …

Faculty Bibliography 2000s

Background: A common SNP upstream of the INSIG2 gene, rs7566605 (g.- 10,1025G > C, Chr2:118,552,255, NT_022135.15), was reported to be associated with obesity (Body Mass Index, [BMI]) in a genome-wide association scan using the Framingham Heart Study but has not been reproduced in other cohorts. As BMI is a relatively insensitive measure of adiposity that is subject to many confounding variables, we sought to determine the relationship between the INSIG2 SNP and subcutaneous fat volumes measured by MRI in a young adult population. Methods: We genotyped the INSIG2 SNP rs7566605 in college-aged population enrolled in a controlled resistance-training program, (the Functional …

Heat Stress In The Intertidal: Comparing Survival And Growth Of An Invasive And Native Mussel Under A Variety Of Thermal Conditions, Kimberly R. Schneider

Faculty Bibliography 2000s

In the rocky intertidal, organisms frequently experience a wide range of daily body temperatures depending on the stage of the tide and the time of day. In the intertidal, the thermal adaption of a species and its ability to invade a new region may be closely linked. In this research, the physiological effects of thermal stress in both low tide and high tide conditions are compared between Mytilus galloprovincialis, a worldwide mussel invader, and M. trossulus, a sibling species. In a seawater tank, mussels were exposed to one of three aerial temperature treatments (20, 25, 30 degrees C) in a …


Codon Choice In Genes Depends On Flanking Sequence Information - Implications For Theoretical Reverse Translation, Karthikeyan Sivaraman, Aswinsainarain Seshasayee, Patrick M. Tarwater, Alexander M. Cole Jan 2008

Codon Choice In Genes Depends On Flanking Sequence Information - Implications For Theoretical Reverse Translation, Karthikeyan Sivaraman, Aswinsainarain Seshasayee, Patrick M. Tarwater, Alexander M. Cole

Faculty Bibliography 2000s

Algorithms for theoretical reverse translation have direct applications in degenerate PCR. The conventional practice is to create several degenerate primers each of which variably encode the peptide region of interest. In the current work, for each codon we have analyzed the flanking residues in proteins and determined their influence on codon choice. From this, we created a method for theoretical reverse translation that includes information from flanking residues of the protein in question. Our method, named the neighbor correlation method (NCM) and its enhancement, the consensus-NCM (c-NCM) performed significantly better than the conventional codon-usage statistic method (CSM). Using the methods …

AIM: To investigate overlapping regions of the rpoB gene previously involved with rifamycin resistance in M. tuberculosis and seek correlation between rpoB mutations in clinical MAP strains with susceptibility to RIF and RFB. METHODS: We designed a molecular-based PCR method for the evaluation of rifabutin (RFB) and rifampicin (RIF) resistance based on probable determinant regions within the rpoB gene of MAP, including the 81 bp variable site located between nucleotides 1363 and 1443. The minimum inhibitory concentration (MIC) for RIF was also determined against 11 MAP isolates in attempt to seek correlation with rpoB sequences. RESULTS: We determined that MAP …


Men Who Have Sex With Men And Recruit Bareback Sex Partners On The Internet: Implications For Sti And Hiv Prevention And Client Education, Christopher W. Blackwell Jan 2008

Men Who Have Sex With Men And Recruit Bareback Sex Partners On The Internet: Implications For Sti And Hiv Prevention And Client Education, Christopher W. Blackwell

Faculty Bibliography 2000s

Men who have sex with men (MSM) frequently use Internet-based Web sites to recruit sex partners. Although many MSM users of such sites advocate for safe sex practices in their personal profiles, some users actively recruit sexual partners who wish to participate in anal sexual intercourse without the use of condoms, also known as "bareback" sex. Participating in this sexual practice places both sexual partners at higher risk of HIV transmission. In addition, data indicate this behavior is associated with other high-risk activities such as drug use and communication of other sexually transmitted infections. This article summarizes the literature assessing …

Determination Of The Degradation Mechanism For Polychlorinated Biphenyl Congeners Using Mechanically Alloyed Magnesium/Palladium, Robert Devor

Electronic Theses and Dissertations

Polychlorinated biphenyls are a ubiquitous environmental contaminant that can be found today throughout the world in soils and sediments, lakes and rivers, and flora and fauna. PCBs have percolated throughout the food chain, so that almost every human being has a detectable amount of the contaminant within their blood stream. Existing remediation methods include incineration, dredging and landfilling, and microbial degradation, but all of these methods have drawbacks that limit their effectiveness as treatment options. Recently, the use of zero-valent metals as a means of reductive dechlorination has been explored. Using a combination of zero-valent magnesium and catalytic palladium, a …


Attachment Style's Impact On The Perception Of Self-Verifying And Self-Enhancing Comforting Messages, Krista Shellabarger Jan 2008

Attachment Style's Impact On The Perception Of Self-Verifying And Self-Enhancing Comforting Messages, Krista Shellabarger

Electronic Theses and Dissertations

This study investigates the connection between one's adult attachment style and one's evaluation of verifying or enhancing comforting messages. Drawing from research by Swann (2005) and Katz and Joiner (2002), the hypothesis predicted that an individual would prefer verifying messages over enhancing messages regardless of attachment style. A research question was also posed: Will an individual's adult attachment style moderate the degree to which a person perceives the communication of verifying or enhancing messages as helpful or effective? In an effort to find these answers, a questionnaire was completed by 251 individuals. Results indicate a preference for verifying messages among …


Using Stable Isotopes To Assess Population Structure And Feeding Ecology Of North Pacific Humpback Whales (Megaptera Novaeangliae), Briana Witteveen Jan 2008

Using Stable Isotopes To Assess Population Structure And Feeding Ecology Of North Pacific Humpback Whales (Megaptera Novaeangliae), Briana Witteveen

Electronic Theses and Dissertations

The North Pacific humpback whale (Megaptera novaeangliae) is a wide-ranging baleen whale species with a complex life history and population structure. As seasonal migrants, humpback whales are known to inhabit cooler, high-latitude waters when foraging and low-latitudes for mating and calving. Beyond this general migratory pattern, a number of demographic characteristics including, abundance, distribution, seasonal occurrence, and prey preferences remain unknown or poorly described. A complete understanding of humpback whale ecology is therefore lacking. Many methods used to explore these aspects of cetacean ecology are either prohibitively expensive or limited in the scope of what can be learned from their …


The Preparedness Of Elementary Music Teachers To Include Students With Challenging Behavior In Their Classrooms, Christine Shirk Jan 2008

The Preparedness Of Elementary Music Teachers To Include Students With Challenging Behavior In Their Classrooms, Christine Shirk

Electronic Theses and Dissertations

Students with disabilities, some with emotional and behavior disorders, are included in almost all elementary music classes. Students with emotional behavior disorders are one of the greatest challenges for teachers. To be effective, teachers must develop strategies and inclusive practices specifically geared towards intervention. With the quantity of students served and only limited class time with students, the music teacher is often unaware of the unique needs of specific special learners. Music teacher preparation has been inadequate in training teachers for inclusion. Elementary music educators rarely have outside support to deal with classroom challenges as they serve students with disabilities …

Overall, concerns that emerged from the study were a lack of heterogeneous classrooms, clarity for the role of the …


The Spiritual Competency Scale: A Comparison To The Aservic Spiritual Competencies, Linda Robertson Jan 2008

The Spiritual Competency Scale: A Comparison To The Aservic Spiritual Competencies, Linda Robertson

Electronic Theses and Dissertations

Spiritual and religious beliefs are significant aspects of a person's worldview and have been well established within many disciplines as a resource for physical and mental health. Therefore, they are relevant topics for counselors. The governing bodies of the counseling profession support the discussion of these beliefs in counseling. To meet the ethical mandates for competency in this area, the Association for Spiritual, Ethical, and Religious Values in Counseling (ASERVIC) produced the Spiritual Competencies. Despite these efforts, spiritual and religious material continues to be neglected in counselor training programs. In the absence of a formal measure of spiritual competency, curricular …

The research was conducted during …


Case Studies Of Reading Performance Of Male Students And The Single-Sex Classroom, Eric Basilo Jan 2008

Case Studies Of Reading Performance Of Male Students And The Single-Sex Classroom, Eric Basilo

Electronic Theses and Dissertations

Data from standardized test scores shows boys are falling further behind in literacy each year. Thanks to countless hours of research, we can pinpoint some of the causes for this decline. The major challenge educators face is how to keep boys interested in reading while placed in classrooms not necessarily designed to meet their needs. One option being explored is the use of single-sex classrooms. For over 160 years in the United States, public school single-sex classrooms have existed. The thought is that by separating boys and girls for academic classes, certain distractions will be eliminated, the environment can be …
