Na/K-Atpase Mimetic Pnaktide Peptide Inhibits The Growth Of Human Cancer Cells, Zhichuan Li, Zhongbing Zhang, Joe X. Xie, Xin Li, Jiang Tian, Ting Cai, Hongaun Cui, Hanfei Ding, Joseph I. Shapiro Md, Zijian Xie

Biochemistry and Microbiology

Cells contain a large pool of non-pumping Na/K-ATPase that participates in signal transduction. Here, we show that the expression of α1 Na/K-ATPase is significantly reduced in human prostate carcinoma as well as in several human cancer cell lines. This down-regulation impairs the ability of Na/K-ATPase to regulate Src-related signaling processes. Supplement of pNaKtide, a peptide derived from α1 Na/K-ATPase, reduces activities of Src and Src effectors. Consequently, these treatments stimulate apoptosis and inhibit growth in cultures of human cancer cells. Moreover, administration of pNaKtide inhibits angiogenesis and growth of tumor xenograft. Thus, the new findings demonstrate the in vivo effectiveness …

Epigenetic Silencing Of Nucleolar Rrna Genes In Alzheimer's Disease, Maciej Pietrzak, Grzegorz Rempala, Peter T. Nelson, Jing-Juan Zheng, Michal Hetman

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: Ribosomal deficits are documented in mild cognitive impairment (MCI), which often represents an early stage Alzheimer's disease (AD), as well as in advanced AD. The nucleolar rRNA genes (rDNA), transcription of which is critical for ribosomal biogenesis, are regulated by epigenetic silencing including promoter CpG methylation.

METHODOLOGY/PRINCIPAL FINDINGS: To assess whether CpG methylation of the rDNA promoter was dysregulated across the AD spectrum, we analyzed brain samples from 10 MCI-, 23 AD-, and, 24 age-matched control individuals using bisulfite mapping. The rDNA promoter became hypermethylated in cerebro-cortical samples from MCI and AD groups. In parietal cortex, the rDNA promoter …

Olfaction And Sexuality, Michael Buxbaum, Md

Jefferson Journal of Psychiatry

A patient who describes himself as "sanitary" told me of his concern with odors. Whenever he thinks about establishing a sexual relationship , he develops a fear that his partner may smell offensive, especially around her genital area. He describes signs and symptoms of sympathetic overactivity when he engages in foreplay, and is afraid that he might be impotent if he smells anything offensive. In fact, he has to insert a finger into his partner's vagina during foreplay, to test the nature of the odor. He feels relieved when the smell is neutral or perfumed, and demonstrates enhanced sexual performance. …

Comparison Of Adenoviruses As Oncolytics And Cancer Vaccines In An Immunocompetent B Cell Lymphoma Model, Eric A. Weaver, Christopher Y. Chen, Shannon M. May, Mary E. Barry, Michael A. Barry

Nebraska Center for Virology: Faculty Publications

We have screened human adenoviruses (Ads) for oncolytic activity against a variety of mouse and hamster cell lines and have found a number that are susceptible to a variety of Ad serotypes. A20 lymphoma is derived from BALB/c mice and is susceptible to infection and killing by a variety of human Ads. A20 is also a suitable cancer vaccine model, because these cells express a unique immunoglobulin variable region that can be targeted by vaccination. To compare Ads as cancer vaccines versus Ads as oncolytics, A20 tumors were initiated in immunocompetent BALB/c mice. Mice immunized with first-generation Ad5 expressing the …

Reactive oxygen species (ROS) are mutagenic and may thereby promote cancer. Normally, ROS levels are tightly controlled by an inducible antioxidant program that responds to cellular stressors and is predominantly regulated by the transcription factor Nrf2 (also known as Nfe2l2) and its repressor protein Keap1 (refs 2-5). In contrast to the acute physiological regulation of Nrf2, in neoplasia there is evidence for increased basal activation of Nrf2. Indeed, somatic mutations that disrupt the Nrf2-Keap1 interaction to stabilize Nrf2 and increase the constitutive transcription of Nrf2 target genes were recently identified, indicating that enhanced ROS detoxification and additional Nrf2 functions may …

Microglial P38Α Mapk Is A Key Regulator Of Proinflammatory Cytokine Up-Regulation Induced By Toll-Like Receptor (Tlr) Ligands Or Beta-Amyloid (Aβ), Adam D. Bachstetter, Bin Xing, Lucia De Almeida, Edgardo R. Dimayuga, D. Martin Watterson, Linda J. Van Eldik

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: Overproduction of proinflammatory cytokines from activated microglia has been implicated as an important contributor to pathophysiology progression in both acute and chronic neurodegenerative diseases. Therefore, it is critical to elucidate intracellular signaling pathways that are significant contributors to cytokine overproduction in microglia exposed to specific stressors, especially pathways amenable to drug interventions. The serine/threonine protein kinase p38α MAPK is a key enzyme in the parallel and convergent intracellular signaling pathways involved in stressor-induced production of IL-1β and TNFα in peripheral tissues, and is a drug development target for peripheral inflammatory diseases. However, much less is known about the quantitative …

Ceacam1 Separates Graft-Versus-Host-Disease From Graft-Versus-Tumor Activity After Experimental Allogeneic Bone Marrow Transplantation., Sydney X Lu, Lucy W Kappel, Anne-Marie Charbonneau-Allard, Renée Atallah, Amanda M Holland, Claire Turbide, Vanessa M Hubbard, Jimmy A Rotolo, Marsinay Smith, David Suh, Christopher King, Uttam K Rao, Nury Yim, Johanne L Bautista, Robert R Jenq, Olaf Penack, Il-Kang Na, Chen Liu, George Murphy, Onder Alpdogan, Richard S Blumberg, Fernando Macian, Kathryn V Holmes, Nicole Beauchemin, Marcel R M Van Den Brink

Department of Medical Oncology Faculty Papers

BACKGROUND: Allogeneic bone marrow transplantation (allo-BMT) is a potentially curative therapy for a variety of hematologic diseases, but benefits, including graft-versus-tumor (GVT) activity are limited by graft-versus-host-disease (GVHD). Carcinoembryonic antigen related cell adhesion molecule 1 (Ceacam1) is a transmembrane glycoprotein found on epithelium, T cells, and many tumors. It regulates a variety of physiologic and pathological processes such as tumor biology, leukocyte activation, and energy homeostasis. Previous studies suggest that Ceacam1 negatively regulates inflammation in inflammatory bowel disease models.

METHODS: We studied Ceacam1 as a regulator of GVHD and GVT after allogeneic bone marrow transplantation (allo-BMT) in mouse models. In …

Methods: In a school-based study, pre-tested structured questionnaires were completed by 414 adolescents (14 to 17 years) at six schools in three cities in Pakistan. The chi-squared test and adjusted odds ratio (aOR) with 95% confidence interval (CI) were calculated in a multinomial logistic regression analysis.

Results: Over 80% of the adolescents had unhealthy diets, and 54% were physically inactive. Most adolescents were exposed to passive smoking, and 14% …

Pregnancy Loss And Distress Among U.S. Women, Karina M. Shreffler, Arthur L. Greil, Julia Mcquillan

Department of Sociology: Faculty Publications

Although pregnancy loss—especially miscarriage— is a relatively common experience among reproductive-aged women, much of our understanding about the experience has come from small clinic-based or other nonrepresentative samples. We compared fertility-specific distress among a national sample of 1,284 women who have ever experienced a stillbirth or miscarriage. We found that commitment/attachment to pregnancy that ended in loss as well as current childbearing contexts and attitudes were associated with distress following pregnancy loss. Practitioners working with women or couples who have experienced pregnancy loss should be aware of the importance of characteristics associated with higher distress, such as whether the pregnancy …

Generation Of A Kupffer Cell-Evading Adenovirus For Systemic And Liver-Directed Gene Transfer, Reeti Khare, Shannon M. May, Francesco Vetrini, Eric A. Weaver, Donna Palmer, Amanda Rosewell, Nathan Grove, Philip Ng, Michael A. Barry

Nebraska Center for Virology: Faculty Publications

As much as 90% of an intravenously (i.v.) injected dose of adenovirus serotype 5 (Ad5) is absorbed and destroyed by liver Kupffer cells. Viruses that escape these cells can then transduce hepatocytes after binding factor X (FX). Given that interactions with FX and Kupffer cells are thought to occur on the Ad5 hexon protein, we replaced its exposed hypervariable regions (HVR) with those from Ad6. When tested in vivo in BALB/c mice and in hamsters, the Ad5/6 chimera mediated >10 times higher transduction in the liver. This effect was not due to changes in FX binding. Rather, Ad5/6 appeared to …

Tumor-Derived Interleukin-10 As A Prognostic Factor In Stage Iii Patients Undergoing Adjuvant Treatment With An Autologous Melanoma Cell Vaccine., Amit Mahipal, Mizue Terai, David Berd, Inna Chervoneva, Kashyap Patel, Michael Mastrangelo, Takami Sato

Department of Medical Oncology Faculty Papers

OBJECTIVES: Interleukin-10 (IL-10) downregulates T-cell-mediated immune responses. We studied the association between IL-10 production by freshly isolated melanoma cell suspensions in vitro and overall survival in patients undergoing adjuvant treatment with a vaccine prepared from the same autologous melanoma cells modified with a hapten, dinitrophenyl (DNP).

METHODS: Forty-four patients with cutaneous melanoma (29 stage III and 15 stage IV) were prospectively evaluated. Tumor cells were extracted from metastatic deposits for production of DNP-modified autologous melanoma cell vaccine. Small aliquots of the melanoma cell suspensions were separated prior to vaccine processing and cultured overnight for IL-10 production. Based on a blind …

Psychostimulants As Cognitive Enhancers: The Prefrontal Cortex, Catecholamines And Attention Deficit Hyperactivity Disorder, Craig Berridge, David M. Devilbiss

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Psychostimulants exert behavioral-calming and cognition-enhancing actions in the treatment of attention deficit hyperactivity disorder (ADHD). Contrary to early views, extensive research demonstrates that these actions are not unique to ADHD. Specifically, when administered at low and clinically-relevant doses, psychostimulants improve a variety of behavioral and cognitive processes dependent on the prefrontal cortex (PFC) in subjects with and without ADHD. Despite the longstanding clinical use of these drugs, the neural mechanisms underlying their cognition-enhancing/therapeutic actions have only recently begun to be examined. At behaviorally-activating doses, psychostimulants produce large and widespread increases in extracellular levels of brain catecholamines. In contrast, cognition-enhancing doses …

Sonic Hedgehog Dependent Phosphorylation By Ck1Α And Grk2 Is Required For Ciliary Accumulation And Activation Of Smoothened, Yongbin Chen, Noriaki Sasai, Guoqiang Ma, Tao Yue, Jianhang Jia, James Briscoe, Jin Jiang

Markey Cancer Center Faculty Publications

Hedgehog (Hh) signaling regulates embryonic development and adult tissue homeostasis through the GPCR-like protein Smoothened (Smo), but how vertebrate Smo is activated remains poorly understood. In Drosophila, Hh dependent phosphorylation activates Smo. Whether this is also the case in vertebrates is unclear, owing to the marked sequence divergence between vertebrate and Drosophila Smo (dSmo) and the involvement of primary cilia in vertebrate Hh signaling. Here we demonstrate that mammalian Smo (mSmo) is activated through multi-site phosphorylation of its carboxyl-terminal tail by CK1α and GRK2. Phosphorylation of mSmo induces its active conformation and simultaneously promotes its ciliary accumulation. We demonstrate that …

Successful Aging And The Epidemiology Of Hiv, David E. Vance, Teena Mcguinness, Karen Musgrove, Nancy Ann Orel, Pariya L. Fazeli

Gerontology Faculty Publications

By 2015, it is estimated that nearly half of those living with HIV in the US will be 50 years of age and older. This dramatic change in the demographics of this clinical population represents unique challenges for patients, health care providers, and society-at-large. Fortunately, because of highly active antiretroviral therapy (HAART) and healthy lifestyle choices, it is now possible for many infected with HIV to age successfully with this disease; however, this depends upon one’s definition of successful aging. It is proposed that successful aging is composed of eight factors: length of life, biological health, cognitive efficiency, mental health, …

Integrin-Linked Kinase: A Scaffold Protein Unique Among Its Ilk, Lina Dagnino

Paediatrics Publications

Integrin-linked kinase (ILK) is a scaffolding protein with central roles in tissue development and homeostasis. Much debate has focused on whether ILK is a bona fide or a pseudo- kinase. This aspect of ILK function has been complicated by the large volumes of conflicting observations obtained from a wide variety of experimental approaches, from in vitro models, to analyses in invertebrates and in mammals. Key findings in support or against the notion that ILK is catalytically active are summarized. The importance of ILK as an adaptor protein is well established, and defining its role as a signaling hub will be …

The Prevalence And Factors Associated With Nonadherence With Arv Treatment And Cotrimoxazole Preventive Therapy Among Hiv Infected Adolescents Attending Out-Patient Hiv Clinics In Kenya, Reson Marima

Master of Medicine in Paediatrics and Child Health

Background: There is an increase in the burden of HIV infected adolescents, both those perinatally infected as well as those acquiring HIV during adolescence. Female adolescents continue to be at the highest risk for acquiring HIV; in many Southern African countries, they have a three fold risk of acquiring HIV compared to their male counterparts. Adherence to treatment among adolescents has been shown to range between 30-70%, which is unacceptably low for antiretroviral therapy (ART). Psychosocial wellbeing and social support have been shown to be possible contributing factors to adherence to ART. This relationship has not been previously evaluated among …

The Role Of Protein Kinase C Epsilon In Hydrogen Peroxide And Nitric Oxide Release During Oxidative Stress Caused By Extracorporeal Shockwave Lithotripsy, Edward S. Iames

PCOM Biomedical Studies Student Scholarship

Clinical extracorporeal shock wave lithotripsy (ESWL) treatment to ablate kidney stones can cause acute damage to the renal microvasculature. Accumulation of continued treatment with shockwave therapy can lead to chronic damage to the kidney, and lead to clinical hypertension. Shockwaves have been shown to stimulate endothelial cells to release superoxide (SO), which is converted to hydrogen peroxide (H₂O₂), and reacts with nitric oxide (NO) to produce peroxynitrite anion (OONO^-), creating a powerful oxidant that increases oxidative stress while simultaneously reducing NO bioavailability. Increased oxidative stress during events such as ESWL, also uncouples NO production …

Relationship Of Vitamin D Levels To Blood Pressure In A Biethnic Cohort, Rosario O. Sakamoto

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Serum hydroxyvitamin D [25(OH)D] has been well-accepted as not an ordinary vitamin but a pro-hormone that has many benefits beyond its well-known effects on bone. Cardiovascular risk factors such as hypertension remain a huge health burden and Blacks have been recognized to have higher prevalence of hypertension compared to non-Hispanic Whites. Despite increasing evidence of the benefits of vitamin D on blood pressure control, there is much more to be learned about the relationship of serum 25(OH)D to blood pressure among different ethnicities.

Purpose: The goal of this study was to determine whether vitamin D serum 25(OH)D levels were …

Acute Effects Of A Selective Cannabinoid-2 Receptor Agonist On Neuroinflammation In A Model Of Traumatic Brain Injury., Melanie B Elliott, Ronald F Tuma, Peter S Amenta, Mary F Barbe, Jack I Jallo

Department of Neurosurgery Faculty Papers

Proposed therapeutic strategies for attenuating secondary traumatic brain injury (TBI) include modulation of acute neuroimmune responses. The goal of this study was to examine the acute effects of cannabinoid-2 receptor (CB(2)R) modulation on behavioral deficits, cerebral edema, perivascular substance P, and macrophage/microglial activation in a murine model of TBI. Thirty male C57BL/6 mice underwent sham surgery, or cortical contusion impact injury (CCI). CCI mice received vehicle or the CB(2)R agonist 0-1966 at 1 and 24 h after injury. Performance on the rotarod, forelimb cylinder, and open-field tests were evaluated before and at 48 h after sham or CCI surgery. Cerebral …

Endothelial Differentiation Of Adipose-Derived Stem Cells From Elderly Patients With Cardiovascular Disease., Ping Zhang, Neil Moudgill, Eric Hager, Nicolas Tarola, Christopher Dimatteo, Stephen Mcilhenny, Thomas Tulenko, Paul J Dimuzio

Department of Surgery Faculty Papers

Adipose-derived stem cells (ASCs) possess significant therapeutic potential for tissue engineering and regeneration. This study investigates the endothelial differentiation and functional capacity of ASCs isolated from elderly patients. Isolation of ASCs from 53 patients (50-89 years) revealed that advanced age or comorbidity did not negatively impact stem cell harvest; rather, higher numbers were observed in older donors (>70 years) than in younger. ASCs cultured in endothelial growth medium-2 for up to 3 weeks formed cords upon Matrigel and demonstrated acetylated-low-density lipoprotein and lectin uptake. Further stimulation with vascular endothelial growth factor and shear stress upregulated endothelial cell-specific markers (CD31, …
