Modulation Of Il-27 In Adipocytes During Inflammatory Stress, Heesun Nam, Bradley S. Ferguson, Jacqueline M. Stephens, Ron F. Morrison

Faculty Publications

© 2015 The Obesity Society. Objective While it is well established that adipose tissue-derived inflammation plays an important role in the pathogenic mechanisms linking obesity with metabolic dysfunction, the inflammatory mediators involved have not been fully elucidated. Here, we explored IL-12 family cytokines with a focus on IL-27 during obesity-induced inflammation in mice and cultured adipocytes (ADs) following exposure to inflammatory stimuli. Methods Relative mRNA abundance of IL-12 cytokines was assessed by reverse transcription polymerase chain reaction (RT-PCR) in genetically obese B6-ob/ob mice as well as C57BL/6J mice fed a high-fat diet and in ADs following exposure to inflammatory stimuli. …

Obesity Impairs Skeletal Muscle Regeneration Through Inhibition Of Ampk, Xing Fu, Meijun Zhu, Shuming Zhang, Marc Foretz, Benoit Viollet, Min Du

Faculty Publications

© 2016 by the American Diabetes Association. Obesity is increasing rapidly worldwide and is accompanied by many complications, including impaired muscle regeneration. The obese condition is known to inhibit AMPK activity in multiple tissues. We hypothesized that the loss of AMPK activity is a major reason for hampered muscle regeneration in obese subjects. We found that obesity inhibits AMPK activity in regenerating muscle, which was associated with impeded satellite cell activation and impaired muscle regeneration. To test the mediatory role of AMPKα1, we knocked out AMPKα1 and found that both proliferation and differentiation of satellite cells are reduced after injury …

Tip Enhanced Laser Ablation Sample Transfer For Mass Spectrometry, Kermit K. Murray, Suman Ghorai, Chinthaka A. Seneviratne

Faculty Publications

© 2015 Materials Research Society. Mass spectrometry is one of the primary analysis techniques for biological analysis but there are technological barriers in sampling scale that must be overcome for it to be used to its full potential on the size scale of single cells. Current mass spectrometry imaging methods are limited in spatial resolution when analyzing large biomolecules. The goal of this project is to use atomic force microscope (AFM) tip enhanced laser ablation to remove material from cells and tissue and capture it for subsequent mass spectrometry analysis. The laser ablation sample transfer system uses an AFM stage …

Comparison Of Electrophysiological Auditory Measures In Fishes, Karen P. Maruska, Joseph A. Sisneros

Faculty Publications

© Springer International Publishing Switzerland 2016. Sounds provide fishes with important information used to mediate behaviors such as predator avoidance, prey detection, and social communication. How we measure auditory capabilities in fishes, therefore, has crucial implications for interpreting how individual species use acoustic information in their natural habitat. Recent analyses have highlighted differences between behavioral and electrophysiologically determined hearing thresholds, but less is known about how physiological measures at different auditory processing levels compare within a single species. Here we provide one of the first comparisons of auditory threshold curves determined by different recording methods in a single fish species, …

Coloration In The Polymorphic Frog Oophaga Pumilio Associates With Level Of Aggressiveness In Intraspecific And Interspecific Behavioral Interactions, Sandra P. Galeano, Kyle E. Harms

Faculty Publications

© 2015, Springer-Verlag Berlin Heidelberg. Intraspecific morphological variation may correspond to behavioral variation that helps determine the nature of species interactions. Color variation among populations of variably toxic organisms has been shown to associate with alternative anti-predator behaviors. However, the effects of these alternative behavioral tendencies on the outcomes of interspecific interactions other than predator–prey remain largely unexplored. We investigated how coloration and body size variation in Oophaga pumilio, one of the most phenotypically diverse amphibians known, associated with territorial aggressiveness and how this association influenced the outcome of agonistic male–male interactions with conspecifics and heterospecifics of two sympatric species …

Liposomes With Diverse Compositions Are Protected During Desiccation By Lea Proteins From Artemia Franciscana And Trehalose, Daniel S. Moore, Richard Hansen, Steven C. Hand

Faculty Publications

© 2015 Published by Elsevier B.V. Intracellular accumulation of Late Embryogenesis Abundant (LEA) proteins and the disaccharide trehalose is associated with cellular desiccation tolerance in a number of animal species. Two LEA proteins from anhydrobiotic embryos of the brine shrimp Artemia franciscana were tested for the ability to protect liposomes of various compositions against desiccation-induced damage in the presence and absence of trehalose. Damage was assessed by carboxyfluorescein leakage after drying and rehydration. Further, using a cytoplasmic-localized (AfrLEA2) and a mitochondrial-targeted (AfrLEA3m) LEA protein allowed us to evaluate whether each may preferentially stabilize membranes of a particular lipid composition based …

Crawling With Virus: Translational Insights From A Neonatal Mouse Model On The Pathogenesis Of Respiratory Syncytial Virus In Infants, Dahui You, Jordy Saravia, David Siefker, Bishwas Shrestha, Stephania A. Cormier

Faculty Publications

© 2015, American Society for Microbiology. The infant immune response to respiratory syncytial virus (RSV) remains incompletely understood. Here we review the use of a neonatal mouse model of RSV infection to mimic severe infection in human infants. We describe numerous age-specific responses, organized by cell type, observed in RSV-infected neonatal mice and draw comparisons (when possible) to human infants.

Autophagy Is Essential For Ultrafine Particle-Induced Inflammation And Mucus Hyperproduction In Airway Epithelium, Zhi Hua Chen, Yin Fang Wu, Ping Li Wang, Yan Ping Wu, Zhou Yang Li, Yun Zhao, Jie Sen Zhou, Chen Zhu, Chao Cao, Yuan Yuan Mao, Feng Xu, Bei Bei Wang, Stephania A. Cormier, Song Min Ying, Wen Li, Hua Hao Shen

Faculty Publications

© 2016 Taylor & Francis Group, LLC. Environmental ultrafine particulate matter (PM) is capable of inducing airway injury, while the detailed molecular mechanisms remain largely unclear. Here, we demonstrate pivotal roles of autophagy in regulation of inflammation and mucus hyperproduction induced by PM containing environmentally persistent free radicals in human bronchial epithelial (HBE) cells and in mouse airways. PM was endocytosed by HBE cells and simultaneously triggered autophagosomes, which then engulfed the invading particles to form amphisomes and subsequent autolysosomes. Genetic blockage of autophagy markedly reduced PM-induced expression of inflammatory cytokines, e.g. IL8 and IL6, and MUC5AC in HBE cells. …

Plastic And Evolved Responses To Global Change: What Can We Learn From Comparative Transcriptomics?, Melissa B. Debiasse, Morgan W. Kelly

Faculty Publications

© The American Genetic Association. 2015. All rights reserved. Physiological plasticity and adaptive evolution may facilitate persistence in a changing environment. As a result, there is an interest in understanding species' capacities for plastic and evolved responses, and the mechanisms by which these responses occur. Transcriptome sequencing has become a powerful tool for addressing these questions, providing insight into otherwise unobserved effects of changing conditions on organismal physiology and variation in these effects among individuals and populations. Here, we review recent studies using comparative transcriptomics to understand plastic and evolutionary responses to changing environments. We focus on 2 areas where …

Biological Control Activities Of Rice-Associated Bacillus Sp. Strains Against Sheath Blight And Bacterial Panicle Blight Of Rice, Bishnu K. Shrestha, Hari Sharan Karki, Donald E. Groth, Nootjarin Jungkhun, Jong Hyun Ham

Faculty Publications

Potential biological control agents for two major rice diseases, sheath blight and bacterial panicle blight, were isolated from rice plants in this study. Rice-associated bacteria (RABs) isolated from rice plants grown in the field were tested for their antagonistic activities against the rice pathogens, Rhizoctonia solani and Burkholderia glumae, which cause sheath blight and bacterial panicle blight, respectively. Twenty-nine RABs were initially screened based on their antagonistic activities against both R. solani and B. glumae. In follow-up retests, 26 RABs of the 29 RABs were confirmed to have antimicrobial activities, but the rest three RABs did not reproduce any observable …

Pteridine Levels And Head Weights Are Correlated With Age And Colony Task In The Honey Bee, Apis Mellifera, Frank D. Rinkevich, Joseph W. Margotta, Jean M. Pittman, James A. Ottea, Kristen B. Healy

Faculty Publications

Background. The age of an insect strongly influences many aspects of behavior and reproduction. The interaction of age and behavior is epitomized in the temporal polyethism of honey bees in which young adult bees perform nurse and maintenance duties within the colony, while older bees forage for nectar and pollen. Task transition is dynamic and driven by colony needs. However, an abundance of precocious foragers or overage nurses may have detrimental effects on the colony. Additionally, honey bee age affects insecticide sensitivity. Therefore, determining the age of a set of individual honey bees would be an important measurement of colony …

Cognitive Phenotypes And The Evolution Of Animal Decisions, Tamra C. Mendelson, Courtney L. Fitzpatrick, Mark E. Hauber, Charles H. Pence, Rafael L. Rodríguez, Rebecca J. Safran, Caitlin A. Stern, Jeffrey R. Stevens

Faculty Publications

Despite the clear fitness consequences of animal decisions, the science of animal decision making in evolutionary biology is underdeveloped compared with decision science in human psychology. Specifically, the field lacks a conceptual framework that defines and describes the relevant components of a decision, leading to imprecise language and concepts. The ‘judgment and decision-making’ (JDM) framework in human psychology is a powerful tool for framing and understanding human decisions, and we apply it here to components of animal decisions, which we refer to as ‘cognitive phenotypes’. We distinguish multiple cognitive phenotypes in the context of a JDM framework and highlight empirical …
