Estimates Of Heritability For Reproductive Traits In Captive Rhesus Macaque Females, Christine Gagliardi, Kathrine P. Falkenstein, Donald E. Franke, H. Michael Kubisch Sep 2010

Estimates Of Heritability For Reproductive Traits In Captive Rhesus Macaque Females, Christine Gagliardi, Kathrine P. Falkenstein, Donald E. Franke, H. Michael Kubisch

Faculty Publications

Records from a colony of captive Indian rhesus macaques (Macaca mulatta) were used to estimate heritability for a number of reproductive traits. Records were based on a total of 7,816 births by 1,901 females from 1979 to 2007. Heritability was estimated with a linear animal model using a multiple trait derivative free REML set of programs. Because no male parents were identified, the numerator relationship matrix contained female kinships established over six generations. Reproductive traits included female age at the birth of the first, second and last infant, age at death, inter-birth intervals, number of infants born per female and …

Uncertainty Compensation In Human Attention: Evidence From Response Times And Fixation Durations, S. Lee Hong, Melissa R. Beck Aug 2010

Uncertainty Compensation In Human Attention: Evidence From Response Times And Fixation Durations, S. Lee Hong, Melissa R. Beck

Faculty Publications

Background: Uncertainty and predictability have remained at the center of the study of human attention. Yet, studies have only examined whether response times (RT) or fixations were longer or shorter under levels of stimulus uncertainty. To date, no study has examined patterns of stimuli and responses through a unifying framework of uncertainty. Methodology/Principal Findings: We asked 29 college students to generate repeated responses to a continuous series of visual stimuli presented on a computer monitor. Subjects produced these responses by pressing on a keypad as soon a target was detected (regardless of position) while the durations of their visual fixations …

Metabolic Preconditioning Of Cells With Aicar-Riboside: Improved Cryopreservation And Cell-Type Specific Impacts On Energetics And Proliferation, Michael A. Menze, Nilay Chakraborty, Matthew Clavenna, Mitali Banerjee, Xiang Hong Liu, Mehmet Toner, Steven C. Hand Aug 2010

Metabolic Preconditioning Of Cells With Aicar-Riboside: Improved Cryopreservation And Cell-Type Specific Impacts On Energetics And Proliferation, Michael A. Menze, Nilay Chakraborty, Matthew Clavenna, Mitali Banerjee, Xiang Hong Liu, Mehmet Toner, Steven C. Hand

Faculty Publications

In species whose evolutionary history has provided natural tolerance to dehydration and freezing, metabolic depression is often a pre-requisite for survival. We tested the hypothesis that preconditioning of mammalian cells with 5-aminoimidazole-4-carboxamide-1-b-d-ribofuranoside (AICAR) to achieve metabolic depression will promote greater survivorship during cryopreservation. AICAR is used extensively to stimulate AMP-activated protein kinase (AMPK), which can result in downregulation of biosynthetic processes. We showed that the metabolic interconversion of AICAR was cell-type dependent. Accumulation of 5-aminoimidazole-4-carboxamide-1b-d-ribofuranosyl-5'-monophosphate (ZMP), as well as other metabolites that possess multiple phosphates (i.e., ZDP, ZTP), varied approximately 3.5-fold across the cell lines tested. AICAR treatment also significantly …

Cryptotanshinone Inhibits Cancer Cell Proliferation By Suppressing Mammalian Target Of Rapamycin - Mediated Cyclin D1 Expression And Rb Phosphorylation, Wenxing Chen, Yan Luo, Lei Liu, Hongyu Zhou, Baoshan Xu, Xiuzhen Han, Tao Shen, Zhijun Liu, Yin Lu, Shile Huang Aug 2010

Cryptotanshinone Inhibits Cancer Cell Proliferation By Suppressing Mammalian Target Of Rapamycin - Mediated Cyclin D1 Expression And Rb Phosphorylation, Wenxing Chen, Yan Luo, Lei Liu, Hongyu Zhou, Baoshan Xu, Xiuzhen Han, Tao Shen, Zhijun Liu, Yin Lu, Shile Huang

Faculty Publications

Cryptotanshinone (CPT), a natural compound isolated from the plant Salvia miltiorrhiza Bunge, is a potential anticancer agent. However, little is known about its anticancer mechanism. Here, we show that CPT inhibited cancer cell proliferation by arresting cells in G1-G0 phase of the cell cycle. This is associated with the inhibition of cyclin D1 expression and retinoblastoma (Rb) protein phosphorylation. Furthermore, we found that CPT inhibited the signaling pathway of the mammalian target of rapamycin (mTOR), a central regulator of cell proliferation. This is evidenced by the findings that CPT inhibited type I insulin-like growth factor I- or 10% fetal bovine …

Gimble, Frank Greenway, Jacqueline M. Stephens, Randall L. Mynatt, Vishwa Deep Dixit

Faculty Publications

Emerging evidence suggests that increases in activated T cell populations in adipose tissue may contribute toward obesity-associated metabolic syndrome. The present study investigates three unanswered questions: 1) Do adipose-resident T cells (ARTs) from lean and obese mice have altered cytokine production in response to TCR ligation?; 2) Do the extralymphoid ARTs possess a unique TCR repertoire compared with lymphoid-resident T cells and whether obesity alters the TCR diversity in specific adipose depots?; and 3) Does short-term elimination of T cells in epididymal fat pad without disturbing the systemic T cell homeostasis regulate inflammation and insulin-action during obesity? We found that …

Genetic Evidence For High Propagule Pressure And Long-Distance Dispersal In Monk Parakeet (Myiopsitta Monachus) Invasive Populations, Anders Gonçalves Da Silva, Jessica R. Eberhard, Timothy F. Wright, Michael L. Avery, Michael A. Russello Aug 2010

Genetic Evidence For High Propagule Pressure And Long-Distance Dispersal In Monk Parakeet (Myiopsitta Monachus) Invasive Populations, Anders Gonçalves Da Silva, Jessica R. Eberhard, Timothy F. Wright, Michael L. Avery, Michael A. Russello

Faculty Publications

The monk parakeet (Myiopsitta monachus) is a successful invasive species that does not exhibit life history traits typically associated with colonizing species (e.g., high reproductive rate or long-distance dispersal capacity). To investigate this apparent paradox, we examined individual and population genetic patterns of microsatellite loci at one native and two invasive sites. More specifically, we aimed at evaluating the role of propagule pressure, sexual monogamy and long-distance dispersal in monk parakeet invasion success. Our results indicate little loss of genetic variation at invasive sites relative to the native site. We also found strong evidence for sexual monogamy from patterns of …

A New Lysozyme From The Eastern Oyster, Crassostrea Virginica, And A Possible Evolutionary Pathway For I-Type Lysozymes In Bivalves From Host Defense To Digestion, Qinggang Xue, Michael E. Hellberg, Kevin L. Schey, Naoki Itoh, Ron I. Eytan, Richard K. Cooper, Jerome F. La Peyre Jul 2010

A New Lysozyme From The Eastern Oyster, Crassostrea Virginica, And A Possible Evolutionary Pathway For I-Type Lysozymes In Bivalves From Host Defense To Digestion, Qinggang Xue, Michael E. Hellberg, Kevin L. Schey, Naoki Itoh, Ron I. Eytan, Richard K. Cooper, Jerome F. La Peyre

Faculty Publications

Background. Lysozymes are enzymes that lyse bacterial cell walls, an activity widely used for host defense but also modified in some instances for digestion. The biochemical and evolutionary changes between these different functional forms has been well-studied in the c-type lysozymes of vertebrates, but less so in the i-type lysozymes prevalent in most invertebrate animals. Some bivalve molluscs possess both defensive and digestive lysozymes. Results. We report a third lysozyme from the oyster Crassostrea virginica, cv-lysozyme 3. The chemical properties of cv-lysozyme 3 (including molecular weight, isoelectric point, basic amino acid residue number, and predicted protease cutting sites) suggest it …

Behavioral And Physiological Plasticity: Rapid Changes During Social Ascent In An African Cichlid Fish, Karen P. Maruska, Russell D. Fernald Jul 2010

Behavioral And Physiological Plasticity: Rapid Changes During Social Ascent In An African Cichlid Fish, Karen P. Maruska, Russell D. Fernald

Faculty Publications

In many vertebrates, reproduction is regulated by social interactions in which dominant males control access to females and food. Subordinate males that displace dominant individuals must rapidly adopt behavioral and physiological traits of the higher rank to gain reproductive success. To understand the process of phenotypic plasticity during social ascent, we analyzed the temporal expression pattern of dominance behaviors and circulating androgen levels when socially-suppressed males of an African cichlid fish Astatotilapia burtoni ascended in status. These experiments tested a prediction of the 'challenge hypothesis' that, during periods of social instability, male androgen levels are higher than during socially stable …

Salivary Gland Thrombostasin Isoforms Differentially Regulate Blood Uptake Of Horn Flies Fed On Control- And Thrombostasin-Vaccinated Cattle, Mary S. Cupp, Eddie W. Cupp, Christine Navarre, Dunhua Zhang, Xin Yue, Latora Todd, Victor Panangala

Faculty Publications

Thrombostasin (TS) is an anticlotting protein found in saliva of Haematobia irritons (horn flies). The polymorphic nature of the ts gene was first associated with success of horn flies blood feeding on a laboratory host, New Zealand White rabbits. In this study, we report results of similar studies testing blood uptake of horn flies feeding on a natural host, cattle. These studies confirmed the association of ts genotype with blood uptake of horn flies and showed that it was host species specific. In contrast to rabbits, blood uptake volumes of homozygous ts10 horn flies were lower than those of other …

Faculty Publications

In the United States, petroleum extraction, refinement, and transportation present countless opportunities for spillage mishaps. A method for rapid field appraisal and mapping of petroleum hydrocarbon-contaminated soils for environmental cleanup purposes would be useful. Visible near-infrared (VisNIR, 350-2500 nm) diffuse reflectance spectroscopy (DRS) is a rapid, nondestructive, proximal-sensing technique that has proven adept at quantifying soil properties in situ. The objective of this study was to determine the prediction accuracy of VisNIR DRS in quantifying petroleum hydrocarbons in contaminated soils. Forty-six soil samples (including both contaminated and reference samples) were collected from six different parishes in Louisiana. Each soil sample …

Host Behaviour And Exposure Risk In An Insect-Pathogen Interaction, Benjamin J. Parker, Bret D. Elderd, Greg Dwyer Jul 2010

Host Behaviour And Exposure Risk In An Insect-Pathogen Interaction, Benjamin J. Parker, Bret D. Elderd, Greg Dwyer

Faculty Publications

1. Studies of variability in host resistance to disease generally emphasize variability in susceptibility given exposure, neglecting the possibility that hosts may vary in behaviours that affect the risk of exposure. 2. In many insects, horizontal transmission of baculoviruses occurs when larvae consume foliage contaminated by the cadavers of virus-infected conspecific larvae; so, host behaviour may have a strong effect on the risk of infection. 3. We studied variability in the behaviour of gypsy moth (Lymantria dispar) larvae, which are able to detect and avoid virus-contaminated foliage. 4. Our results show that detection ability can be affected by the family …

Biogeographic Anomaly Or Human Introduction: A Cryptogenic Population Of Tree Skink (Reptilia: Squamata) From The Cook Islands, Oceania, Alison M. Hamilton, George R. Zug, Christopher C. Austin Jun 2010

Biogeographic Anomaly Or Human Introduction: A Cryptogenic Population Of Tree Skink (Reptilia: Squamata) From The Cook Islands, Oceania, Alison M. Hamilton, George R. Zug, Christopher C. Austin

Faculty Publications

Archaeological and molecular data have revealed that the present day faunas of many island groups in Melanesia, Polynesia, and Micronesia are not representative of the biodiversity generated within this region on an evolutionary timescale. Erroneous inferences regarding the mechanisms of speciation and the significance of long distance dispersal in shaping the present diversity of these island systems have resulted from this incomplete diversity and distributional data. The lizard fauna east of Samoa has been suggested to derive entirely from human-mediated introductions, a distribution congruent with biogeographic patterns for other Pacific species. Distinguishing between introduced populations and those that result from …

Historical Divergence And Gene Flow: Coalescent Analyses Of Mitochondrial, Autosomal And Sex-Linked Loci In Passerina Buntings, Matthew D. Carling, Irby J. Lovette, Robb T. Brumfield Jun 2010

Historical Divergence And Gene Flow: Coalescent Analyses Of Mitochondrial, Autosomal And Sex-Linked Loci In Passerina Buntings, Matthew D. Carling, Irby J. Lovette, Robb T. Brumfield

Faculty Publications

Quantifying the role of gene flow during the divergence of closely related species is crucial to understanding the process of speciation. We collected DNA sequence data from 20 loci (one mitochondrial, 13 autosomal, and six sex-linked) for population samples of Lazuli Buntings (Passerina amoena) and Indigo Buntings (Passerina cyanea) (Aves: Cardinalidae) to test explicitly between a strict allopatric speciation model and a model in which divergence occurred despite postdivergence gene flow. Likelihood ratio tests of coalescent-based population genetic parameter estimates indicated a strong signal of postdivergence gene flow and a strict allopatric speciation model was rejected. Analyses of partitioned datasets …

High Amino Acid Diversity And Positive Selection At A Putative Coral Immunity Gene (Tachylectin-2), Marshall L. Hayes, Ron I. Eytan, Michael E. Hellberg May 2010

High Amino Acid Diversity And Positive Selection At A Putative Coral Immunity Gene (Tachylectin-2), Marshall L. Hayes, Ron I. Eytan, Michael E. Hellberg

Faculty Publications

Background. Genes involved in immune functions, including pathogen recognition and the activation of innate defense pathways, are among the most genetically variable known, and the proteins that they encode are often characterized by high rates of amino acid substitutions, a hallmark of positive selection. The high levels of variation characteristic of immunity genes make them useful tools for conservation genetics. To date, highly variable immunity genes have yet to be found in corals, keystone organisms of the world's most diverse marine ecosystem, the coral reef. Here, we examine variation in and selection on a putative innate immunity gene from Oculina, …

Performance, Properties And Plasticity Of Identified Oxytocin And Vasopressin Neurones In Vitro, William E. Armstrong, L. Wang, C. Li, R. Teruyama May 2010

Performance, Properties And Plasticity Of Identified Oxytocin And Vasopressin Neurones In Vitro, William E. Armstrong, L. Wang, C. Li, R. Teruyama

Faculty Publications

The neurohypophysial hormones oxytocin (OT) and vasopressin (VP) originate from hypothalamic neurosecretory cells in the paraventricular and supraoptic (SON) nuclei. The firing rate and pattern of action potentials arising from these neurones determine the timing and quantity of peripheral hormone release. We have used immunochemical identification of biocytin-filled SON neurones in hypothalamic slices in vitro to uncover differences between OT and VP neurones in membrane and synaptic properties, firing patterns, and plasticity during pregnancy and lactation.In this review, we summarise some recent findings from this approach: (i) VP neuronal excitability is influenced by slow (sDAP) and fast (fDAP) depolarising afterpotentials …

Siamese Cooperates With The Cdh1-Like Protein Ccs52a1 To Establish Endoreplication In Arabidopsis Thaliana Trichomes, Remmy Kasili, Jason D. Walker, L. Alice Simmons, Jing Zhou, Lieven De Veylder, John C. Larkin May 2010

Siamese Cooperates With The Cdh1-Like Protein Ccs52a1 To Establish Endoreplication In Arabidopsis Thaliana Trichomes, Remmy Kasili, Jason D. Walker, L. Alice Simmons, Jing Zhou, Lieven De Veylder, John C. Larkin

Faculty Publications

Endoreplication, also known as endoreduplication, is a phyogenetically widespread modified version of the cell cycle in which DNA replication is not followed by cell division. The SIAMESE (SIM) gene of Arabidopsis thaliana encodes the founding member of a novel class of plant-specific cyclin-dependent kinase (CDK) inhibitors and is a key regulator of endoreplication during the development of trichomes (shoot epidermal hairs). Here, we have identified mutations in the CCS52A1 gene as genetic modifiers of the multicellular trichome phenotype of sim mutants. Loss-of-function ccs52A1 mutations dramatically enhance the multicellularity of sim mutants trichomes in double mutants, whereas overexpression of CCS52A1 completely …
