Nuclear Envelope Laminopathies: Evidence For Developmentally Inappropriate Chromatin-Nuclear Envelope Interactions, Jelena Perovanovic, Jyoti K. Jaiswal, Nikola Markovic, Eric P. Hoffman

Genomics and Precision Medicine Faculty Publications

Background

During terminal differentiation of cells, there is typically a transition of the nuclear envelope from the Lamin B protein to Lamin A/C proteins. This is commensurate with exit from the cell cycle, and maintenance of the transcriptional programs associated with the terminally differentiated cells. Dominant missense mutations in Lamin A/C cause a broad spectrum of human genetic disorders, where specific point mutations are associated with defects in specific organs or tissues. We have previously presented a model where Lamin A/C mutations disrupt developmentally appropriate interactions between chromatin and the nuclear envelope and lead to poor coordination of E2F cell …

Dux4 Expression In Fshd Muscle Cells: How Could Such A Rare Protein Cause A Myopathy?, Alexandra Tassin, Dalila Laoudj-Chenivesse, Celine Vanderplanck, Marietta Barro, Sebastien Charron, Eugenie Ansseau, Yi-Wen Chen, Jacques Mercier, Frederique Coppee, Alexandra Belayew

Genomics and Precision Medicine Faculty Publications

Facioscapulohumeral muscular dystrophy (FSHD) is one of the most frequent hereditary muscle disorders. It is linked to contractions of the D4Z4 repeat array in 4q35. We have characterized the double homeobox 4 (DUX4) gene in D4Z4 and its mRNA transcribed from the distal D4Z4 unit to a polyadenylation signal in the flanking pLAM region. It encodes a transcription factor expressed in FSHD but not healthy muscle cells which initiates a gene deregulation cascade causing differentiation defects, muscle atrophy and oxidative stress.PITX1 was the first identified DUX4 target and encodes a transcription factor involved in muscle atrophy. DUX4 was …

Highlights From The Functional Single Nucleotide Polymorphisms Associated With Human Muscle Size And Strength Or Famuss Study, Linda S. Pescatello, Joseph M. Devaney, Monica J. Hubal, Paul D. Thompson, Eric P. Hoffman

Genomics and Precision Medicine Faculty Publications

The purpose of the Functional Single Nucleotide Polymorphisms Associated with Human Muscle Size and Strength study or FAMuSS was to identify genetic factors that dictated the response of health-related fitness phenotypes to resistance exercise training (RT). The phenotypes examined were baseline muscle strength and muscle, fat, and bone volume and their response to RT. FAMuSS participants were 1300 young (24 years), healthy men (42%) and women (58%) that were primarily of European-American descent. They were genotyped for ~500 polymorphisms and completed the Paffenbarger Physical Activity Questionnaire to assess energy expenditure and time spent in light, moderate, and vigorous intensity habitual …

Systems Biology In Animal Breeding: Identifying Relationships Among Markers, Genes, And Phenotypes [Breeding And Genetics Symposium], John B. Cole, Ronald M. Lewis, C. Maltecca, S. Newman, K. M. Olson, R. G. Tait

Department of Animal Science: Faculty Publications

The Breeding and Genetics Symposium titled “Systems Biology in Animal Breeding: Identifying relationships among markers, genes, and phenotypes” was held at the Joint Annual Meeting of the American Society of Animal Science and the American Dairy Science Association in Phoenix, Arizona, July 15-19, 2012. The primary goal of the symposium was to demonstrate the use of high-density SNP genotypes to determine the complex regulatory relationships among genotypes and phenotypes but also to present methods for studying complex relationships among phenotypes. Case studies from mammalian and avian species were included to emphasize the broad applicability of these methods.

Progress Towards A Phylogeny Of World Tachinidae. Year 1, John O. Stireman Iii, James E. O'Hara, Michael C. Moulton, Pierfilippo Cerretti, Isaac S. Winkler

Biological Sciences Faculty Publications

D eveloping a structural phylogenetic framework for the family Tachinidae has been an interest of mine since I first started working on tachinids as a graduate student. It was then that I developed a new phylogenetic perspective with which to view the world, and many of the questions I wanted to ask of tachinids depended on some level of phylogenetic knowledge of them. I was surprised at the time that no one had attempted a broad quantitative phylogenetic analysis of the family, and a publication from my thesis work on the Exoristinae (Stireman 2002) became the first such study that …

Food Limitation As A Potentially Emerging Contributor To The Asian Vulture Crisis, Fakhar -I- Abbas, Thomas P. Rooney, Jibran Haider, Afsar Mian

Biological Sciences Faculty Publications

It was believed that the reason for decline in Asian vulture population is the drug, Diclofenac sodium (DFS), used in livestock. Even after declaring the DFS use banned by the government, apparent decrease in the population of vultures was reported. Alternate hypothesis was suggested that food limitation may be a cause of Asian vulture crisis in Pakistan. Very recent shifts in livestock utilization observed in Pakistan may present a significant barrier to vulture recovery. Increased livestock utilization is translated to fewer carcasses. Since 2005, no livestock carcasses were found in 1650 km transect in the habitat of vultures. Carcasses recorded …

Game-Based Curricula In Biology Classes: Multi-Level Assessment Of Science Learning, Troy D. Sadler, William L. Romine, Parker E. Stuart

Biological Sciences Faculty Publications

Video games played on computers, game consoles, tablets and smart phones have become a very popular medium in our society. A growing body of scholarship suggests that video games can support substantial learning (for reviews see Gee, 2007; Honey & Hilton, 2011; Squire, 2011). Research has documented ways in which games engage students deeply in thinking, learning, and collaboration (Gee, 2005). Evidence suggests that games can support development of critical thinking (Squire, 2006), creativity (Annetta, Cheng, & Holmes, 2010), and mastery and application of target concepts (Squire, 2011).

To 'Die Hel' And Back. Expeditions Of The Phylogeny Of World Tachinidae Project. Part I: Western Cape, South Africa, Pierfilippo Cerretti, James E. O'Hara, John O. Stireman Iii, Isaac S. Winkler, Ashley H. Kirk-Spriggs

Biological Sciences Faculty Publications

The “Phylogeny of World Tachinidae” project kicked off with an operational meeting in June 2012 at the Canadian National Collection of Insects (CNC) in Ottawa. Goals were discussed, work plans prepared, and of course the destinations and timing of major field expeditions were debated. During our three years of National Science Foundation funding we hope to gather fresh material for molecular analysis from all biogeographic regions of the world.

Terrestrial And Semi-Aquatic Vertebrates In Diets Of Largemouth Bass In Central Nebraska, Seth A. Lundgren, Keith Geluso, Casey W. Schoenebeck

The Prairie Naturalist

Largemouth bass (Micropterus salmoides) are opportunistic predators often feeding in littoral areas during crepuscular periods (Snow 1971). Adult largemouth bass primarily are piscivorous, whereas juveniles generally consume zooplankton, insects, and small fish (Zweiacker and Summerfelt 1974, Carlander 1977, Post 2003). Age-0 largemouth bass generally consume zooplankton and macroinvertebrates (Keast and Webb 1966, Keast 1985, Phillips et al. 1995, Post 2003) and shift to piscivory at 50-70 mm in length (Phillips et al. 1995, Olson 1996, Post 2003). Few studies have documented detailed accounts of other vertebrates besides fish in diets of largemouth bass, which include amphibians (Hodgson and …

Differential Activity Of The Kras Oncogene By Method Of Activation: Implications For Signaling And Therapeutic Intervention, Nathan Ihle

Dissertations and Theses (Open Access)

Despite having been identified over thirty years ago and definitively established as having a critical role in driving tumor growth and predicting for resistance to therapy, the KRAS oncogene remains a target in cancer for which there is no effective treatment. KRas is activated b y mutations at a few sites, primarily amino acid substitutions at codon 12 which promote a constitutively active state. I have found that different amino acid substitutions at codon 12 can activate different KRas downstream signaling pathways, determine clonogenic growth potential and determine patient response to molecularly targeted therapies. Computer modeling of the KRas structure …

Fish Assemblage Structure In Black Hills, South Dakota Streams, Luke D. Schultz, Sarah J. Lewis, Katie Nicole Bertrand

The Prairie Naturalist

Understanding factors structuring fish assemblages in a particular area is valuable to both sport fishery management and native species conservation. Fish assemblages in the Black Hills are unique to South Dakota because they contain economically valuable introduced salmonids as well as native species of conservation need. Our objective was to examine the relationship between fish assemblages and geomorphic and reach-scale habitat features across multiple stream reaches in the Black Hills. Canonical correspondence analysis, a direct gradient ordination analysis, indicated that factors operating at multiple spatial scales interacted to structure fish assemblages. There also was indication of segregation between native species …

The Incentive And Benefits To Publish Research, Christopher N. Jacques

The Prairie Naturalist

In the northern Great Plains, December is a month marked by the end of the year and a period of much-needed rest and relaxation during the start of the winter season. Landscapes will soon be blanketed with snow and local floral and faunal species have adapted to the ensuing winter months ahead. Winter is a season that reminds you who you live in the Plains states, and as such, should expect bitter cold temperatures, strong winds, and blowing and drifting snow. However, December is a great time to enjoy the outdoors across the Great Plains, a time to reflect on …
