The Expression Of Ecotropic Virus Integration Site-1 In Seven Cancer Cell Lines, Wendy Bindeman '12

Student Publications & Research

The ecotropic virus integration site-1 (EVI1) gene is a transcriptional repressor implicated in the control of cell proliferation and frequently over-expressed in cancerous cells. I investigated the expression of this gene across seven cancer cell lines of varying morphologies. The tested lines included leukemia lines Kasumi-3, U937, MOLT-4, and CEM, breast cancer line MCF7, colorectal cancer line HT-29, and glioblastoma line M059K. Kasumi-3 and HT-29 are documented to have high EVI1 expression. Protein concentrations were normalized with respect to actin using SDS-PAGE and Western blotting. Western blots for EVI1 showed expression of an unidentified protein with a molecular weight of …

Molecular Mechanism Of Xy Gonadal Dysgenesis, Griendy Indig-Weingarten

The Science Journal of the Lander College of Arts and Sciences

One of the fundamentals of human sociology is the characterization of the people around us based on gender. We tend to think of gender as a strict binary system where the option is clear: boy or girl. Although society usually honors this dichotomy, biology allows more flexibility to the definition of male versus female. Estimates state that one in every 2000 births is one with a disorder of sex development (The Intersex Society of North America 2006). Some of the disorders are visually obvious while others are only discovered later on in life. Regardless of when the disease first becomes …

Shared Resistance To Aging And Als In Neuromuscular Junctions Of Specific Muscles, Gregorio Valdez, Juan C. Tapia, Jeff W. Lichtman, Michael A. Fox, Joshua R. Sanes

Anatomy and Neurobiology Publications

Normal aging and neurodegenerative diseases both lead to structural and functional alterations in synapses. Comparison of synapses that are generally similar but respond differently to insults could provide the basis for discovering mechanisms that underlie susceptibility or resistance to damage. Here, we analyzed skeletal neuromuscular junctions (NMJs) in 16 mouse muscles to seek such differences. We find that muscles respond in one of three ways to aging. In some, including most limb and trunk muscles, age-related alterations to NMJs are progressive and extensive during the second postnatal year. NMJs in other muscles, such as extraocular muscles, are strikingly resistant to …

The Effect Of Load On Movement Coordination During Sled Towing, Michael Lawrence, Daniel Leib, Cara Masterson, Erin Hartigan

Daniel Leib

INTRODUCTION Towing sleds while walking is a popular resistance exercise for the healthy athlete. One reason for the popularity of sled towing is that it is widely believed to be a ‘functional’ exercise. Preliminary research suggests towing while walking can increases lower extremity moment impulses; however whether towing a sled utilizes the same coordination patterns as un-resisted walking is unknown. While altered patterns may not be as relevant to a healthy athlete, sled towing is also sometimes used in the rehabilitation of athletes who sustained a lower extremity injury (anterior cruciate ligament rupture) with the goal of regaining movement symmetry. …

Computerized Tomography Providing Definitive Diagnosis Of Colonic Lipoma: A Case Series, Osama M. Moussa Mr, Sanaa Arshad Dr, Ming Tee Dr, Aref U. Khan Mr, Chelliah R. Selvasekar Mr

Osama M Moussa Mr

Lipomas are common benign mesenchymal tumors. They can develop in virtually all organs throughout the body. Colonic lipomas are uncommon, benign, submucosal adipose tumors that are usually asymptomatic. Large lipomas can cause symptoms such as constipation, abdominal pain, rectal bleeding and intussusception. We report a case series of two colonic submucosal lipomas with different presentations, elaborating the importance of computerised tomography (CT) imaging in the diagnosis.

Optogenetic Stimulation Of The Corticothalamic Pathway Affects Relay Cells And Gabaergic Neurons Differently In The Mouse Visual Thalamus, Chris W. D. Jurgens, Karen A. Bell, A. Rory Mcquiston, William Guido

Anatomy and Neurobiology Publications

The dorsal lateral geniculate nucleus (dLGN) serves as the primary conduit of retinal information to visual cortex. In addition to retinal input, dLGN receives a large feedback projection from layer VI of visual cortex. Such input modulates thalamic signal transmission in different ways that range from gain control to synchronizing network activity in a stimulus-specific manner. However, the mechanisms underlying such modulation have been difficult to study, in part because of the complex circuitry and diverse cell types this pathway innervates. To address this and overcome some of the technical limitations inherent in studying the corticothalamic (CT) pathway, we adopted …

Early Hearing-Impairment Results In Crossmodal Reorganization Of Ferret Core Auditory Cortex, M. Alex Meredith, Brian L. Allman

Anatomy and Neurobiology Publications

Numerous investigations of cortical crossmodal plasticity, most often in congenital or early-deaf subjects, have indicated that secondary auditory cortical areas reorganize to exhibit visual responsiveness while the core auditory regions are largely spared. However, a recent study of adult-deafened ferrets demonstrated that core auditory cortex was reorganized by the somatosensory modality. Because adult animals have matured beyond their critical period of sensory development and plasticity, it was not known if adult-deafening and early-deafening would generate the same crossmodal results. The present study used young, ototoxically-lesioned ferrets () that, after maturation (avg. = 173 days old), showed significant hearing deficits (avg. …

The Fit-Hansa Demonstrates Reliability And Convergent Validity Of Functional Performance In Patients With Shoulder Disorders, Prajyot Kumta, Joy C. Macdermid, Saurabh Mehta, Paul W. Stratford

Physical Therapy Faculty Research

Study

DesignPsychometric study design.

Objectives

To assess the test-retest reliability and convergent validity of the Functional Impairment Test-Hand and Neck/Shoulder/Arm (FIT-HaNSA) in patients with shoulder disorders.

Background

Performance tests that assess functional ability of patients with shoulder disorders can provide useful information for making clinical or return-to-activity decisions. No performance-based shoulder test has yet demonstrated sufficient relevance or clinical measurement properties. The FIT-HaNSA examines upper extremity performance during repetitive tasks that emphasize shoulder reaching and static postures and, therefore, has greater relevance for assessing performance.

Methods

Thirty-six patients with shoulder disorders and 65 healthy controls were recruited for the study. …

Basic Concepts In Understanding Recovery Of Function In Vestibular Reflex Networks During Vestibular Compensation, Kenna D. Peusner, Mei Shao, Rebecca Reddaway, June C. Hirsch

Anatomy and Regenerative Biology Faculty Publications

Unilateral peripheral vestibular lesions produce a syndrome of oculomotor and postural deficits with the symptoms at rest, the static symptoms, partially or completely normalizing shortly after the lesion due to a process known as vestibular compensation. The symptoms are thought to result from changes in the activity of vestibular sensorimotor reflexes. Since the vestibular nuclei must be intact for recovery to occur, many investigations have focused on studying these neurons after lesions. At present, the neuronal plasticity underlying early recovery from the static symptoms is not fully understood. Here we propose that knowledge of the reflex identity and input–output connections …

Targeting The Cancer Cell Cycle By Cold Atmospheric Plasma, Olga Volotskova, Teresa S. Hawley, Mary Ann Stepp, Michael Keidar

Anatomy and Regenerative Biology Faculty Publications

Cold atmospheric plasma (CAP), a technology based on quasi-neutral ionized gas at low temperatures, is currently being evaluated as a new highly selective alternative addition to existing cancer therapies. Here, we present a first attempt to identify the mechanism of CAP action. CAP induced a robust ~2-fold G2/M increase in two different types of cancer cells with different degrees of tumorigenicity. We hypothesize that the increased sensitivity of cancer cells to CAP treatment is caused by differences in the distribution of cancer cells and normal cells within the cell cycle. The expression of γH2A.X (pSer139), an oxidative stress reporter indicating …

The Role Of Corticotropin-Releasing Factor In The Behavior And Proinflammatory Activity Of Separated Guinea Pig Pups, Vincent Rasahd Alexander

Browse all Theses and Dissertations

Isolation of guinea pig pups in a novel environment first produces active behaviors such as vocalizing and movement; over time, these behaviors wane and pups show characteristic passive responses similar to those produced by increased proinflammatory activity. Further, isolation of pups on two consecutive days has recently been shown to enhance those passive responses on the second day. Endogenous proinflammatory activity is thought to mediate the enhancement (sensitization). An injection of corticotropin-releasing factor (CRF) has been shown to increase passive behavior, possibly by increasing proinflammatory activity. The present study further investigated the role of CRF on proinflammatory activity and behavior …
