Regulation Of Pten Inhibition By The Pleckstrin Homology Domain Of P-Rex2 During Insulin Signaling And Glucose Homeostasis, Cindy Hodakoski, Benjamin D. Hopkins, Douglas Barrows, Sarah M. Mense, Megan Keniry, Karen E. Anderson, Philip A. Kern, Phillip T. Hawkins, Len R. Stephens, Ramon Parsons

Clinical and Translational Science Faculty Publications

Insulin activation of phosphoinositide 3-kinase (PI3K) signaling regulates glucose homeostasis through the production of phosphatidylinositol 3,4,5-trisphosphate (PIP3). The dual-specificity phosphatase and tensin homolog deleted on chromosome 10 (PTEN) blocks PI3K signaling by dephosphorylating PIP3, and is inhibited through its interaction with phosphatidylinositol 3,4,5-trisphosphate-dependent Rac exchanger 2 (P-REX2). The mechanism of inhibition and its physiological significance are not known. Here, we report that P-REX2 interacts with PTEN via two interfaces. The pleckstrin homology (PH) domain of P-REX2 inhibits PTEN by interacting with the catalytic region of PTEN, and the inositol polyphosphate 4-phosphatase domain of P-REX2 provides high-affinity binding to the postsynaptic …

Research Brief: "Peer Mentoring And Financial Incentives To Improve Glucose Control In African American Veterans", Institute For Veterans And Military Families At Syracuse University

Institute for Veterans and Military Families

This brief is about whether peer mentoring and financial incentives given to African American veterans with diabetes improves their glucose levels. In policy and practice, African American veterans should join peer mentoring programs to help them control their diabetes and consult with their physician about peer mentoring; the VHA should create a peer mentoring program for veterans with diabetes to help with diabetes management. Suggestions for future research include using a larger, more diverse sample, looking at how the peer mentoring helps veterans, and looking at the ways in which veterans lowered their glucose levels in addition to taking part …

The Concomitant Relationship Shared By Sleep Disturbances And Type 2 Diabetes: Developing Telemedicine As A Viable Treatment Option, Pennie S. Seibert, Jennifer Valerio, Codieann Dehaas

Psychological Sciences Faculty Publications and Presentations

Individually, sleep disturbances and type 2 diabetes pose pervasive challenges to health. In addition, the negative symptomology associated with each condition is exacerbated further when presenting concomitantly. This relationship formulates a destructive loop wherein those with diabetes experience decreased sleep quality, which, in turn, worsens a wide range of health threats experienced by those with diabetes, including obesity and glucose intolerance. Because major lifestyle changes and daily care are needed to effectively manage both diabetes and sleep disturbances, an efficient and timely modality of treatment is essential. Advanced technology incorporating telemedicine and telehealth has the potential to enhance treatment by …

Effects Of Fatty Acids And Glycation On Drug Interactions With Human Serum Albumin, Jeanethe Anguizola, Sara B. G. Basiaga, David S. Hage

David Hage Publications

The presence of elevated glucose concentrations in diabetes is a metabolic change that leads to an increase in the amount of non-enzymatic glycation that occurs for serum proteins. One protein that is affected by this process is the main serum protein, human serum albumin (HSA), which is also an important carrier agent for many drugs and fatty acids in the circulatory system. Sulfonylurea drugs, used to treat type 2 diabetes, are known to have significant binding to HSA. This study employed ultrafiltration and high-performance affinity chromatography to examine the effects of HSA glycation on the interactions of several sulfonylurea drugs …

Diabetic Db/Db Mice Exhibit Central Nervous System And Peripheral Molecular Alterations As Seen In Neurological Disorders., A. Ernst, Ajaykumar Narayan Sharma, Khalid M. Elased, P. C. Guest, H. Rahmoune, S. Bahn

Pharmacology and Toxicology Faculty Publications

The db/db mouse is a widely used preclinical model in diabetes research. Recent studies have shown that these mice also display aspects of psychosis and depression-like behaviors as seen in some psychiatric disorders. Here, we have performed multiplex immunoassay and liquid chromatography mass spectrometry profiling of the plasma and brain samples from db/db and control mice to identify altered pathways, which could be related to these behavioral abnormalities. This is the first study to carry out profiling of the brain proteome in this model. Plasma from the db/db mice had increased levels of leptin and insulin, decreased levels of peptide …

Obesity Indicators By Race/Ethnicity For Diagnosis Of Cardiometabolic Diseases For A Us Representative Sample Of Adults, Joan A. Vaccaro, Fatma G. Huffman

Department of Dietetics and Nutrition

Background: Obesity, a growing epidemic, is a preventable risk factor for cardiometabolic diseases. Obesity and cardiometabolic diseases affect Hispanics and African Americans more than non-Hispanic Caucasians. This study examined the relationship among race/ethnicity, obesity diagnostic measures (body mass index, waist circumference, subscapular and triceps skinfold thickness), and cardiometabolic risk factors (hyperglycemia, high, non-high-density lipoprotein cholesterol, low, high-density lipoprotein cholesterol, and hypertension) for adults across the United States.

Methods: Using data from two-cycles of the National Health and Examination Survey (NHANES) 2007-2010, and accounting for the complex sample design, logistic regression models were conducted comparing obesity indicators in Mexican Americans, other …

The Effect Of Statins On Testosterone In Men And Women, A Systematic Review And Meta-Analysis Of Randomized Controlled Trials, Mary Schooling, Shiu Lun Au Yeung, Guy Freeman, Benjamin J. Cowling

Publications and Research

Background
Statins are extensively used for cardiovascular disease prevention. Statins reduce mortality rates morethan other lipid-modulating drugs, although evidence from randomized controlled trials also suggests that statinsunexpectedly increase the risk of diabetes and improve immune function. Physiologically, statins would beexpected to lower androgens because statins inhibit production of the substrate for the local synthesis of androgens and statins’ pleiotropic effects are somewhat similar to the physiological effects of lowering testosterone, so we hypothesized that statins lower testosterone.

Methods
A meta-analysis of placebo-controlled randomized trials of statins to test the a priori hypothesis that statins lower testosterone. We searched the PubMed, …

Improvement Of Functional Bioactivity In Pear:Blackberry Synergies With Lactic Acid Fermentation For Type 2 Diabetes And Hypertension Management, Nicholas W. Pucel

Masters Theses 1911 - February 2014

Type II diabetes mellitus (T2DM) is a chronic disease that has a worldwide prevalence which is expected to rise dramatically over the course of the next thirty years. The disease has reached pandemic stages of development in many cultures, most notably in developing countries, followed somewhat closely by developed countries with access to an overabundance of refined carbohydrates and fat (refined oils). T2DM is a condition that can be prevented or managed, but not cured; therefore a method of stymieing the development of this disease is paramount to halting its progressively increasing morbidity. In this study, bartlett pear and kiowa …

Faculty of Science, Medicine and Health - Papers: part A

Cognitive impairment occurs in both schizophrenia and diabetes. There is currently limited understanding whether schizophrenia with diabetes has more serious cognitive deficits than schizophrenia without diabetes or diabetes only. This study assessed cognitive performance in 190 healthy controls, 106 diabetes only, 127 schizophrenia without diabetes and 55 schizophrenia with diabetes. This study was conducted from January 2008 to December 2010. Compared to healthy controls, all patient groups had significantly decreased total and five index RBANS scores (all p<0.01-p

Segregation Of A Latent High Adiposity Phenotype In Families With A History Of Type 2 Diabetes Mellitus Implicates Rare Obesity-Susceptibility Genetic Variants With Large Effects In Diabetes-Related Obesity, Arthur B. Jenkins, Marijka Batterham, Dorit Samocha-Bonet, Katherine Tonks, Jerry R. Greenfield, Lesley V. Campbell

Faculty of Science, Medicine and Health - Papers: part A

Background We recently reported significantly greater weight gain in non-diabetic healthy subjects with a 1st degree family history (FH+) of type 2 diabetes mellitus (T2DM) than in a matched control group without such history (FH−) during voluntary overfeeding, implying co-inheritance of susceptibilities to T2DM and obesity. We have estimated the extent and mode of inheritance of susceptibility to increased adiposity in FH+.

Methods Normoglycaemic participants were categorised either FH+ (≥1 1st degree relative with T2DM, 50F/30M, age 45±14 (SD) yr) or FH− (71F/51M, age 43±14 yr). Log-transformed anthropometric measurements (height, hip and waist circumferences) and lean, bone and fat mass …

Background: Diabetic retinopathy can result in impaired photostress recovery time despite normal visual acuity and fundoscopic appearance. The Macular Degeneration Detector (MDD-2) is a novel flash photostress recovery time device. In this study, we examine the repeatability of the MDD-2 in normal and diabetic subjects. Methods: One hundred and ninety one (90 women, 101 men) subjects were recruited and divided into 1 of the 3 study groups (normal controls, n = 40; diabetes no retinopathy, n = 98; nonproliferative diabetic retinopathy, n = 53). Photostress recovery time was measured three times in the study eye using the MDD-2, each measurement …

Distribution And Cluster Analysis Of Predicted Intrinsically Disordered Protein Pfam Domains, Robert W. Williams, Bin Xue, Vladimir N. Uversky, A. Keith Dunker

Molecular Medicine Faculty Publications

The Pfam database groups regions of proteins by how well hidden Markov models (HMMs) can be trained to recognize similarities among them. Conservation pressure is probably in play here. The Pfam seed training set includes sequence and structure information, being drawn largely from the PDB. A long standing hypothesis among intrinsically disordered protein (IDP) investigators has held that conservation pressures are also at play in the evolution of different kinds of intrinsic disorder, but we find that predicted intrinsic disorder (PID) is not always conserved across Pfam domains. Here we analyze distributions and clusters of PID regions in 193024 members …

Disparate Health Implications Stemming From The Propensity Of Elderly And Medically Fragile Populations To Shelter In Place During Severe Storm Events, Joshua G. Behr, Rafael Diaz

VMASC Publications

Chronic conditions, disability limitations (mobility, cognitive, and sensory), and the need for assistance with activities of daily living are characteristics of elderly and medically fragile populations. Theory suggests that households with these vulnerability attributes are more likely to suffer storm-induced adverse and prolonged health consequences and, therefore, ought to evidence an increased propensity to evacuate prior to a severe storm event. Yet despite being more sensitive to storm disruption, the elderly and medically fragile populations are only slightly more likely to evacuate in the face of impending storms. This suggests, for these groups, there may be other factors such as …

Dietary Patterns Associated With Alzheimer's Disease And Related Chronic Disease Risk: A Review, Samantha L. Gardener, Stephanie R. Rainey-Smith, Jennifer Keogh, Suzanne Mathieson, Ralph N. Martins

Research outputs 2013

The world’s population is growing older due to improved healthcare and nutrition. As a result, Alzheimer’s disease (AD) prevalence is rapidly increasing. The focus of the current research climate is shifting from understanding AD pathology and diagnosis to primary prevention and intervention strategies. Diet represents one potential intervention strategy accessible to all. Accumulating evidence suggests diet plays a major role in risk and development of AD and AD-related chronic diseases of the periphery like cardiovascular disease (CVD) and diabetes. This paper reviews studies that have explored the relationship between “a priori” dietary patterns, AD and AD-related chronic disease risk. The …
