Proteoglycans In Health And Disease: Novel Regulatory Signaling Mechanisms Evoked By The Small Leucine-Rich Proteoglycans., Renato V. Iozzo, Liliana Schaefer

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The small leucine-rich proteoglycans (SLRPs) are involved in many aspects of mammalian biology, both in health and disease. They are now being recognized as key signaling molecules with an expanding repertoire of molecular interactions affecting not only growth factors, but also various receptors involved in controlling cell growth, morphogenesis and immunity. The complexity of SLRP signaling and the multitude of affected signaling pathways can be reconciled with a hierarchical affinity-based interaction of various SLRPs in a cell- and tissue-specific context. Here, we review this interacting network, describe new relationships of the SLRPs with tyrosine kinase and Toll-like receptors and critically …

Chemistry: Faculty Publications and Other Works

α-Sulfone-α-piperidine and α-tetrahydropyranyl hydroxamates were explored that are potent inhibitors of MMP’s-2, -9, and -13 that spare MMP-1, with oral efficacy in inhibiting tumor growth in mice and left-ventricular hypertrophy in rats and in the bovine cartilage degradation ex vivo explant system. α-Piperidine 19v (SC-78080/SD-2590) was selected for development toward the initial indication of cancer, while α-piperidine and α-tetrahydropyranyl hydroxamates 19w (SC-77964) and 9i (SC-77774), respectively, were identified as backup compounds.

The Benefits Of Contaminated Site Cleanup Revisited: The Case Of Naples And Caserta, Italy, Anna Alberini, Milan Ščasný, Dennis Guignet, Stefania Tonin

Fondazione Eni Enrico Mattei Working Papers

Guerriero and Cairns (2009) recently estimate that contaminated sites and improper waste management result in 848 excess deaths per year in the provinces of Naples and Caserta in Southern Italy, 403 of which are fatal cancers. In the absence of estimates of the Value of a Prevented Fatality (VPF) in Italy or specific to the hazardous waste context, they use figures recommended by DG-Environment. Contrary to their claims, estimates of the VPF are available for Italy that are specific to the hazardous waste context, and for causes of death that have been linked to contaminated site exposures. We review them …

Kinetics Of Dna And Rna Hybridization In Serum And Serum-Sds, Elton Graugnard, Amber Cox, Jeunghoon Lee, Cheryl Jorcyk, Bernard Yurke, William L. Hughes

Materials Science and Engineering Faculty Publications and Presentations

Cancer is recognized as a serious health challenge both in the United States and throughout the world. While early detection and diagnosis of cancer leads to decreased mortality rates, current screening methods require significant time and costly equipment. Recently, increased levels of certain micro-ribonucleic acids (miRNAs) in the blood have been linked to the presence of cancer. While blood-based biomarkers have been used for years in cancer detection, studies analyzing trace amounts of miRNAs in blood and serum samples are just the beginning. Recent developments in deoxyribonucleic acid (DNA) nanotechnology and DNA computing have shown that it is possible to …

A Mobile Threat To Genome Stability: The Impact Of Non-Ltr Retrotransposons Upon The Human Genome, Miriam K. Konkel, Mark A. Batzer

Faculty Publications

It is now commonly agreed that the human genome is not the stable entity originally presumed. Deletions, duplications, inversions, and insertions are common, and contribute significantly to genomic structural variations (SVs). Their collective impact generates much of the inter-individual genomic diversity observed among humans. Not only do these variations change the structure of the genome; they may also have functional implications, e.g. altered gene expression. Some SVs have been identified as the cause of genetic disorders, including cancer predisposition. Cancer cells are notorious for their genomic instability, and often show genomic rearrangements at the microscopic and submicroscopic level to which …

Metabolic Syndrome And Risk Of Death From Cancers Of The Digestive System, Charles E. Matthews, Xuemei Sui, Michael J. Lamonte, Swann A. Adams, James R. Hébert, Steven N. Blair

Faculty Publications

We tested the hypothesis that risk of early mortality from cancers of the digestive system will be greater in men with, compared to men without, the metabolic syndrome (MetS). Participants were 33,230 men who were seen at the Cooper Clinic in Dallas, Texas and followed for 14.4 (SD=7.0) yrs. MetS was defined as having at least three of the following risk factors: abdominal obesity, fasting hypertriglyceridemia, low high-density lipoprotein cholesterol, high blood pressure, or high fasting glucose level or diabetes. MetS was associated with higher mortality (HR=1.90 [95% Confidence Interval=1.42-2.55]), and there was a graded positive association for the addition …

Mitochondria-Centric Activation Induced Cell Death Of Cytolytic T Lymphocytes And Its Implications For Cancer Immunotherapy, Arvind Chhabra

UCHC Articles - Research

Premature death of the adoptively transferred cytolytic T lymphocytes (CTL) by means of activation induced cell death (AICD) represents one of the major constraints in devising an effective anti-cancer immune intervention strategy. Understanding the mechanism of AICD is, therefore, critical for developing methods to interfere with this death process. Although the existing paradigm on AICD centers around the initiation of the cascade of events originating from the engagement of death receptors leading to the activation of effector caspases and eventually resulting in cell death, recent findings have questioned the universal role of caspases as the cell death executioners. We here …

Ecuador: Chevron Squanders Money As Lawsuit Nears End, Luis Ángel Saavedra

NotiEn: An Analytical Digest About Energy Issues in Latin America

Chevron (formerly ChevronTexaco) wasted millions of dollars to delay the trial brought against it by Ecuador's Amazonian Indians and campesinos for the environmental disaster caused by 20 years of oil exploitation. The verdict is expected to go against the company and to be handed down within the next two months. In 2001, Texaco Petroleum Company was bought by Chevron, which then became ChevronTexaco until 2005 when Chevron dropped Texaco from its name. Texaco extracted petroleum in the Ecuadoran Amazon from 1967 to 1990 in a joint venture with state-owned Petroecuador. As part of its operations, the company built an oil …

Development Of Ultrasonic Detection Methods For Cancer Cells In Vivo, Jeffrey B. Goodrich

Browse All Undergraduate research

A current problem in medicine and specifically breast cancer is the detection of microscopic cancer in surgical margins to ensure all of the cancer has been removed. Current methods rely on extensive pathology work that may take several days to complete. For breast cancer patients, positive findings for cancer in surgical margins require follow-up surgery to remove more tissue. Up to 50% of patients undergoing breast conservation surgery (lumpectomy) require additional surgery. A preferable method would be in vivo microscopic detection for use during surgery. Such methods would reduce risks, costs, and patient suffering that accompany follow-up operations. Ultrasound is …

Inference Of Cancer-Specific Gene Regulatory Networks Using Soft Computing Rules., Xiaosheng Wang, Osamu Gotoh

Journal Articles: Genetics, Cell Biology & Anatomy

Perturbations of gene regulatory networks are essentially responsible for oncogenesis. Therefore, inferring the gene regulatory networks is a key step to overcoming cancer. In this work, we propose a method for inferring directed gene regulatory networks based on soft computing rules, which can identify important cause-effect regulatory relations of gene expression. First, we identify important genes associated with a specific cancer (colon cancer) using a supervised learning approach. Next, we reconstruct the gene regulatory networks by inferring the regulatory relations among the identified genes, and their regulated relations by other genes within the genome. We obtain two meaningful findings. One …

Rbc And Wbc Fatty Acid Composition Following Consumption Of An Omega 3 Supplement: Lessons For Future Clinical Trials, Theodore R. Witte, Alexander J. Salazar, Oscar F. Ballester, W. Elaine Hardman

Biochemistry and Microbiology

Background: Results from increasing numbers of in vitro and in vivo studies have demonstrated that omega 3 fatty acids incorporated in cell culture media or in the diet of the animals can suppress the growth of cancers. When human clinical trials are initiated to determine the ability of omega 3 fatty acids to alter growth or response to chemotherapeutic interventions of cancers, it will be essential to determine the omega 3 intake of individuals in the trial to determine compliance with consumption of the supplement and to correlate with endpoints of efficacy. We wondered if the fatty acid composition of …

Maternal Consumption Of Canola Oil Suppressed Mammary Gland Tumorigenesis In C3(1) Tag Mice Offspring, Gabriela Ion, Juliana A. Akinsete, W. Elaine Hardman

Biochemistry and Microbiology

Background: Maternal consumption of a diet high in omega 6 polyunsaturated fats (n-6 PUFA) has been shown to increase risk whereas a diet high in omega 3 polyunsaturated fats (n-3 PUFA) from fish oil has been shown to decrease risk for mammary gland cancer in female offspring of rats. The aim of this study was to determine whether increasing n-3 PUFA and reducing n-6 PUFA by using canola oil instead of corn oil in the maternal diet might reduce the risk for breast cancer in female offspring.

Methods: Female SV 129 mice were divided into two groups and placed on …

The Role Of Formins In Human Disease, Aaron D. Deward, Kathryn M. Eisenmann, Stephen F. Matheson, Arthur S. Alberts

University Faculty Publications and Creative Works

Formins are a conserved family of proteins that play key roles in cytoskeletal remodeling. They nucleate and processively elongate non-branched actin filaments and also modulate microtubule dynamics. Despite their significant contributions to cell biology and development, few studies have directly implicated formins in disease pathogenesis. This review highlights the roles of formins in cell division, migration, immunity, and microvesicle formation in the context of human disease. In addition, we discuss the importance of controlling formin activity and protein expression to maintain cell homeostasis. © 2009 Elsevier B.V. All rights reserved.

The Possible Role Of Il-17 In Obesity-Associated Cancer, Tiphaine Gislette, Jiezhong Chen

Illawarra Health and Medical Research Institute

Obesity and overweight have become major medical and social problems. Both are increasing worldwide; two-thirds of the population in developed countries is obese or overweight. Obesity has been associated with many comorbidities, including diabetes and heart disease. Studies have also found that obesity is one of the risk factors involved in increased cancer incidence. Many obesity-related factors are responsible, including increased blood levels of insulin/IGF, IL-6, TNF-alpha, and leptin, and decreased blood levels of adiponectin. Recently, it has been shown that IL-17 levels increase in obese patients. IL-17 is well known to increase carcinogenesis; thus, increased IL-17 levels in obesity …

Beliefs And Beyond: What Can We Learn From Qualitative Studies Of Lay People's Understandings Of Cancer Risk?, Wendy Lipworth, Heather M. Davey, Stacy M. Carter, Claire Hooker, Wendy Hu

Faculty of Social Sciences - Papers (Archive)

Background  Clinicians and public health professionals are centrally concerned with mediating risk. However, people often resist the risk-related information that is communicated to them by experts, or have their own models of risk that conflict with expert views. Quantitative studies have clearly demonstrated the importance of health beliefs and various cognitive and emotional processes in shaping risk perception. More recently, a growing body of qualitative research has emerged, exploring lay conceptualizations, experiences and constructions of cancer risk. To date, this literature has not been synthesized. Objective  We report the findings of a synthesis of qualitative literature regarding the ways in …

Is Nasopharyngeal Cancer Really A "Cantonese Cancer"?, Joseph Tien Seng Wee, Tam C. Ha, Susan Loong, Chao-Nan Qian

Faculty of Social Sciences - Papers (Archive)

Nasopharyngeal cancer (NPC) is endemic in Southern China, with Guandong province and Hong Kong reporting some of the highest incidences in the world. The journal Science has called it a "Cantonese cancer". We propose that in fact NPC is a cancer that originated in the Bai Yue ("proto Tai Kadai" or "proto Austronesian" or "proto Zhuang") peoples and was transmitted to the Han Chinese in southern China through intermarriage. However, the work by John Ho raised the profile of NPC, and because of the high incidence of NPC in Hong Kong and Guangzhou, NPC became known as a Cantonese cancer. …

Rapid Calcium-Dependent Activation Of Aurora-A Kinase, Olga V. Plotnikova, Elena N. Pugacheva, Roland L. Dunbrack, Erica A. Golemis

Faculty & Staff Scholarship

Oncogenic hyperactivation of the mitotic kinase Aurora-A (AurA) in cancer is associated with genomic instability. Increasing evidence indicates that AurA also regulates critical processes in normal interphase cells, but the source of such activity has been obscure. We report here that multiple stimuli causing release of Ca2+ from intracellular endoplasmic reticulum stores rapidly and transiently activate AurA, without requirement for second messengers. This activation is mediated by direct Ca2+-dependent calmodulin (CaM) binding to multiple motifs on AurA. On the basis of structure–function analysis and molecular modelling, we map two primary regions of CaM-AurA interaction to unfolded sequences in the AurA …

A Geographical Information System-Based Analysis Of Cancer Mortality And Population Exposure To Coal Mining Activities In West Virginia, United States Of America, Michael Hendryx, Evan Fedorko, Andrew Anesetti-Rothermel

Faculty & Staff Scholarship

Cancer incidence and mortality rates are high in West Virginia compared to the rest of the United States of America. Previous research has suggested that exposure to activities of the coal mining industry may contribute to elevated cancer mortality, although exposure measures have been limited. This study tests alternative specifications of exposure to mining activity to determine whether a measure based on location of mines, processing plants, coal slurry impoundments and underground slurry injection sites relative to population levels is superior to a previously-reported measure of exposure based on tons mined at the county level, in the prediction of age-adjusted …

Adjacent Slice Prostate Cancer Prediction To Inform Maldi Imaging Biomarker Analysis, Shao-Hui Chuang, Xiaoyan Sun, Lisa Cazares, Julius Nyalwidhe, Dean Troyer, O. John Semmes, Jiang Li, Frederic D. Mckenzie, Nico Karssemeijer (Ed.), Ronald M. Summers (Ed.)

Electrical & Computer Engineering Faculty Publications

Prostate cancer is the second most common type of cancer among men in US [1]. Traditionally, prostate cancer diagnosis is made by the analysis of prostate-specific antigen (PSA) levels and histopathological images of biopsy samples under microscopes. Proteomic biomarkers can improve upon these methods. MALDI molecular spectra imaging is used to visualize protein/peptide concentrations across biopsy samples to search for biomarker candidates. Unfortunately, traditional processing methods require histopathological examination on one slice of a biopsy sample while the adjacent slice is subjected to the tissue destroying desorption and ionization processes of MALDI. The highest confidence tumor regions gained from the …

Prostate Cancer Region Prediction Using Maldi Mass Spectra, Ayyappa Vadlamudi, Shao-Hui Chuang, Xiaoyan Sun, Lisa Cazares, Julius Nyalwidhe, Dean Troyer, O. John Semmes, Jiang Li, Frederic D. Mckenzie

Electrical & Computer Engineering Faculty Publications

For the early detection of prostate cancer, the analysis of the Prostate-specific antigen (PSA) in serum is currently the most popular approach. However, previous studies show that 15% of men have prostate cancer even their PSA concentrations are low. MALDI Mass Spectrometry (MS) proves to be a better technology to discover molecular tools for early cancer detection. The molecular tools or peptides are termed as biomarkers. Using MALDI MS data from prostate tissue samples, prostate cancer biomarkers can be identified by searching for molecular or molecular combination that can differentiate cancer tissue regions from normal ones. Cancer tissue regions are …
