Suppression Of F1 Male-Specific Lethality In Caenorhabditis Hybrids By Cbr-Him-8, Vaishnavi Ragavapuram, Emily Elaine King, Scott Everet Baird Dec 2015

Suppression Of F1 Male-Specific Lethality In Caenorhabditis Hybrids By Cbr-Him-8, Vaishnavi Ragavapuram, Emily Elaine King, Scott Everet Baird

Biological Sciences Faculty Publications

Haldane's Rule and Darwin's Corollary to Haldane's Rule are the observations that heterogametic F1 hybrids frequently are less fit than their homogametic siblings and that asymmetric results often are obtained from reciprocal hybrid crosses. In Caenorhabditis, Haldane's Rule and Darwin's Corollary have been observed in several hybrid crosses, including crosses of Caenorhabditis briggsae and Caenorhabditis nigoni. Fertile F1 females are obtained from reciprocal crosses. However, F1 males obtained from C. nigoni mothers are sterile and F1 males obtained from C. briggsae die during embryogenesis. We have identified cbr-him-8 as a recessive maternal-effect suppressor of F1 hybrid male-specific lethality …


Sidestream Smoke Exposure Increases The Susceptibility Of Airway Epithelia To Adenoviral Infection, Priyanka Sharma, Abimbola O. Kolawole, Susan B. Core, Adriana E. Kajon, Katherine J.D.A. Excoffon Nov 2015

Sidestream Smoke Exposure Increases The Susceptibility Of Airway Epithelia To Adenoviral Infection, Priyanka Sharma, Abimbola O. Kolawole, Susan B. Core, Adriana E. Kajon, Katherine J.D.A. Excoffon

Biological Sciences Faculty Publications

Background: Although significant epidemiological evidence indicates that cigarette smoke exposure increases the incidence and severity of viral infection, the molecular mechanisms behind the increased susceptibility of the respiratory tract to viral pathogens are unclear. Adenoviruses are non-enveloped DNA viruses and important causative agents of acute respiratory disease. The Coxsackievirus and adenovirus receptor (CAR) is the primary receptor for many adenoviruses. We hypothesized that cigarette smoke exposure increases epithelial susceptibility to adenovirus infection by increasing the abundance of apical CAR. Methodology and Findings: Cultured human airway epithelial cells (CaLu-3) were used as a model to investigate the effect of sidestream cigarette …


Gene Diversification Of An Emerging Pathogen: A Decade Of Mutation In A Novel Fish Viral Hemorrhagic Septicemia (Vhs) Substrain Since Its First Appearance In The Laurentian Great Lakes, Carol A. Stepien, Lindsey R. Pierce, Douglas W. Leaman, Megan D. Niner, Brian S. Shepherd Aug 2015

Viral Hemorrhagic Septicemia virus (VHSv) is an RNA rhabdovirus, which causes one of the world's most serious fish diseases, infecting >80 freshwater and marine species across the Northern Hemisphere. A new, novel, and especially virulent substrain—VHSv-IVb—first appeared in the Laurentian Great Lakes about a decade ago, resulting in massive fish kills. It rapidly spread and has genetically diversified. This study analyzes temporal and spatial mutational patterns of VHSv-IVb across the Great Lakes for the novel non-virion (Nv) gene that is unique to this group of novirhabdoviruses, in relation to its glycoprotein (G), phosphoprotein (P), …


Macroecology Of North American Suckers (Catostomidae): Tests Of Bergmann's And Rapoport's Rules, Stephen J. Jacquemin, Jason C. Doll Aug 2015

Macroecology Of North American Suckers (Catostomidae): Tests Of Bergmann's And Rapoport's Rules, Stephen J. Jacquemin, Jason C. Doll

Biological Sciences Faculty Publications

Discerning spatial macroecological patterns in freshwater fishes has broad implications for community assembly, ecosystem dynamics, management, and conservation. This study explores the potential interspecific covariation of geographic range (Rapoport's rule) and body size (Bergmann's rule) with latitude in North American sucker fishes (Cypriniformes: Catostomidae). While numerous tests of Rapoport's and Bergmann's rules are documented in the literature, comparatively few of these studies have specifically tested for these patterns, and none have incorporated information reflecting shared ancestry into analyses of North American freshwater fish through a hierarchical model. This study utilized a hierarchical modeling approach with Bayesian inference to evaluate the …

The Quest For Ash Resistance To Eab: Towards A Mechanistic Understanding, Daniel A. Herms, Don Cipollini, K. S. Knight, J. L. Koch, T. M. Poland, Chad Michael Rigsby, Justin G.A. Whitehill, Pierluigi Bonello Jan 2015

The Quest For Ash Resistance To Eab: Towards A Mechanistic Understanding, Daniel A. Herms, Don Cipollini, K. S. Knight, J. L. Koch, T. M. Poland, Chad Michael Rigsby, Justin G.A. Whitehill, Pierluigi Bonello

Biological Sciences Faculty Publications

Since emerald ash borer (EAB), Agrilus planipennis, was discovered in North America in 2002, it has killed many millions of ash trees in North America, and ash mortality now exceeds 99% near the epicenter of the invasion in southeast Michigan (Klooster et al. 2014). The development of EAB-resistant ash trees will be critical for restoration of ash in natural and urban forests. Goals of our collaboration are to identify, breed and screen ash germplasm for EAB resistance and silvicultural traits; and identify mechanisms of EAB resistance to facilitate breeding and screening.

The Implications Of Hiv Treatment On The Hiv-Malaria Coinfection Dynamics: A Modeling Perspective, F. Nyabadza, B. T. Bekele, Megan A. Rúa, D. M. Malonza, N. Chiduku, M. Kgosimore

Biological Sciences Faculty Publications

Most hosts harbor multiple pathogens at the same time in disease epidemiology. Multiple pathogens have the potential for interaction resulting in negative impacts on host fitness or alterations in pathogen transmission dynamics. In this paper we develop a mathematical model describing the dynamics of HIV-malaria coinfection. Additionally, we extended our model to examine the role treatment (of malaria and HIV) plays in altering populations’ dynamics. Our model consists of 13 interlinked equations which allow us to explore multiple aspects of HIV-malaria transmission and treatment. We perform qualitative analysis of the model that includes positivity and boundedness of solutions. Furthermore, we …


Characterization Of Calbindin Positive Interneurons Within The Ventral Horn Of The Mouse Spinal Cord, Taylor L. Floyd, David R. Ladle Jan 2015

Characterization Of Calbindin Positive Interneurons Within The Ventral Horn Of The Mouse Spinal Cord, Taylor L. Floyd, David R. Ladle

Symposium of Student Research, Scholarship, and Creative Activities Materials

Sensory-motor circuits in the spinal cord integrate sensory feedback from muscles and modulate locomotor behavior. Although we know how the sensory-motor system generally works, the main issue lies in identifying all neurons involved and understanding their interrelationships. Many interneurons contribute to sensory-motor circuits and have been well studied. For example, Renshaw cells (RC) are inhibitory interneurons that prevent motor neurons from over-activity. A distinguishing feature of RCs is that they are the only interneurons within the ventral-most region of the spinal cord expressing the calcium binding protein calbindin (CB). Recent studies have found other subpopulations of ventral horn interneurons outside …


Expression Of The Nkcc2a Cotransporter In Mouse Central Nervous System, Katherine E. Fahy, James B. Lucot, Hayo Castrop, Mauricio Di Fulvio Jan 2015

Expression Of The Nkcc2a Cotransporter In Mouse Central Nervous System, Katherine E. Fahy, James B. Lucot, Hayo Castrop, Mauricio Di Fulvio

Symposium of Student Research, Scholarship, and Creative Activities Materials

Na-K-2Cl cotransporter 2A (NKCC2A), also known as the bumetanide-sensitive cotransporter 1 (BSC1), transports Na+, K+ and Cl- with a stoichiometry of 1:1:2. NKCC2A is considered a kidney specific cotransporter. It is abundantly expressed in apical membrane of the tubular cells in the thick ascending limb of the loop of Henle (TALH) and in the macula densa. However, NKCC2 has also been found at low levels in different cells, including insulin-secreting ones. This secondary active transporter uses the energy stored in the electrochemical gradients of Na and K maintained by the Na/K-ATPase located on the basolateral membrane of the TALH. The …
