Background Parkinson’s disease (PD) is a progressive neurodegenerative disorder that leads to altered neural control of movement, including the control of voice, respiration, and swallowing. There is a prevalent need to provide therapy for voice, respiration, and swallowing difficulties because current pharmacological and surgical treatments do not effectively treat these impairments. Previous research has demonstrated that singing may be a treatment option to target voice, respiratory, and swallowing impairments, as well as quality of life. However, participants’ perspectives related to reasons for enrolling and engaging in programs as well as evaluation of singing programs have been neglected.

Recent studies have found an association between functional variants in TREM2 and PLD3 and Alzheimer's disease (AD), but their effect on cognitive function is unknown. We examined the effect of these variants on cognitive function in 1449 participants from the Wisconsin Registry for Alzheimer's Prevention, a longitudinal study of initially asymptomatic adults, aged 36–73 years at baseline, enriched for a parental history of AD. A comprehensive cognitive test battery was performed at up to 5 visits. A factor analysis resulted in 6 cognitive factors that were standardized into z scores (∼N [0, 1]); the mean of these ...

KGI Theses and Dissertations
Huntington’s disease (HD) is a debilitating neurodegenerative disorder with a complex pathophysiology. Despite extensive studies to study the disease, the sequence of events through which mutant Huntingtin (mHtt) protein executes its action still remains elusive. The phenotype of HD is an outcome of numerous processes initiated by the mHtt protein along with other proteins that act as either suppressors or enhancers of the effects of mHtt protein and PolyQ aggregates. Utilizing an integrative systems biology approach, I construct and analyze a Huntington’s disease integrome using human orthologs of protein interactors of wild type and mHtt protein. Analysis of ...
Evaluation Of Immune-Modulating Therapies For Parkinson's Disease, 2017 University of Nebraska Medical Center
Evaluation Of Immune-Modulating Therapies For Parkinson's Disease, Katherine E. Olson
Theses & Dissertations
Parkinson’s disease (PD) is the second most common neurodegenerative
disorder, second only to Alzheimer’s disease (AD). It is characterized by a
progressive loss of dopaminergic neurons along the nigrostriatal axis and the
formation of proteinaceous inclusions of alpha-synuclein (α-syn). Secondary to
the loss of dopaminergic neurons is a progression in motor and non-motor
symptoms. Motor symptoms are characterized by slowness in movement,
stiffness and tremor. Non-motor symptoms include depression, constipation,
sleep abnormalities and loss of sense of smell. The cause of disease remains
incompletely understood. However, age, genetics, environment, viral infection,
and interplay between the innate and adaptive ...
Structural Insights Into The Potency Of Sk Channel Positive Modulators, 2017 Chapman University
Structural Insights Into The Potency Of Sk Channel Positive Modulators, Young-Woo Nam, Razan Orfali, Tingting Liu, Kunqian Yu, Meng Cui, Heike Wulff, Miao Zhang
Pharmacy Faculty Articles and Research
Small-conductance Ca2+-activated K+ (SK) channels play essential roles in the regulation of cellular excitability and have been implicated in neurological and cardiovascular diseases through both animal model studies and human genetic association studies. Over the past two decades, positive modulators of SK channels such as NS309 and 1-EBIO have been developed. Our previous structural studies have identified the binding pocket of 1-EBIO and NS309 that is located at the interface between the channel and calmodulin. In this study, we took advantage of four compounds with potencies varying over three orders of magnitude, including 1-EBIO, NS309, SKS-11 (6-bromo-5-methyl-1H-indole-2 ...

Pitx3null Mutant (Striatal Dopamine-Deficient) Mice Have Exaggerated Spiny Projection Neuron Responses To L-Dopa And D1 Agonism And Lack Baseline Striatonigral Spiking, Ben Sagot
Theses and Dissertations (ETD)
L-3,4 dihidroxyphenylalanine (l-DOPA) strongly stimulates motor activity in parkinsonian patients and animal models of Parkinson's disease. Severe striatal dopamine (DA) loss characterizes Parkinson's disease and its animal models. Given the canonical rate model of Parkinson's Disease pathophysiology based on differences in DA pharmacology manifesting as electrophysiological differences in striatal projection neuron (SPN) spike rates, SPNs should increase spiking during the motor response to l-DOPA. In fact, stimulating specific subsets of these neurons to spike in freely-moving wild type and parkinsonian animals causes or inhibits motor activity as predicted. However, pharmacological effects of DA deficiency, let alone ...

Neurology Faculty Publications
An X-linked condition characterized by the combination of hypomyelinating leukodystrophy and spondylometaphyseal dysplasia (H-SMD) has been observed in only four families, with linkage to Xq25-27, and recent genetic characterization in two families with a common AIFM1 mutation. In our study, 12 patients (6 families) with H-SMD were identified and underwent comprehensive assessment accompanied by whole-exome sequencing (WES). Pedigree analysis in all families was consistent with X-linked recessive inheritance. Presentation typically occurred between 12 and 36 months. In addition to the two disease-defining features of spondylometaphyseal dysplasia and hypomyelination on MRI, common clinical signs and symptoms included motor deterioration, spasticity, tremor ...
The Role Of Rnf4 In Stripping Transcriptionally-Active Huntingtin, 2017 College of William and Mary
The Role Of Rnf4 In Stripping Transcriptionally-Active Huntingtin, Jen Peek
Undergraduate Honors Theses
Altered gene expression is a hallmark of neurodegenerative disorders such as Huntington’s disease. The causative agent of Huntington’s is a mutant, aggregation-prone fragment of huntingtin (htt) that aggregates in the cytosol and nuclei of neuronal cells. The severity and onset of Huntington’s is correlated with the length of a polyglutamine (Q) tract encoded in the N-terminus of htt. Little is known about the nuclear accumulation of polyQ expanded htt, how it interacts with chromatin, and dysregulates transcriptional activity. In this thesis, we investigate the effect of nuclear localized htt on reporter gene activation and demonstrate that the ...
Effect Of Src Kinase Inhibition On Cytochrome C, Smac/Diablo And Apoptosis Inducing Factor (Aif) Following Cerebral Hypoxia-Ischemia In Newborn Piglets., Panagiotis Kratimenos, Ioannis Koutroulis, Beamon Agarwal, Stamatios Theocharis, Maria Delivoria-Papadopoulos
Pediatrics Faculty Publications
We have previously shown that cerebral Hypoxia-ischemia (HI) results in activation of Src kinase in the newborn piglet brain. We investigated the regulatory mechanism by which the pre-apoptotic proteins translocate from mitochondria to the cytosol during HI through the Src kinase. Newborn piglets were divided into 3 groups (n = 5/group): normoxic (Nx), HI and HI pre-treated with Src kinase inhibitor PP2 (PP2 + HI). Brain tissue HI was verified by neuropathological analysis and by Adenosine Triphosphate (ATP) and Phosphocreatine (PCr) levels. We used western blots, immunohistochemistry, H&E and biochemical enzyme assays to determine the role of Src kinase on ...
Targeted Genetic Screen In Amyotrophic Lateral Sclerosis Reveals Novel Genetic Variants With Synergistic Effect On Clinical Phenotype, Pamela J. Shaw, Kevin P. Kenna, John E. Landers
Open Access Articles
Amyotrophic lateral sclerosis (ALS) is underpinned by an oligogenic rare variant architecture. Identified genetic variants of ALS include RNA-binding proteins containing prion-like domains (PrLDs). We hypothesized that screening genes encoding additional similar proteins will yield novel genetic causes of ALS. The most common genetic variant of ALS patients is a G4C2-repeat expansion within C9ORF72. We have shown that G4C2-repeat RNA sequesters RNA-binding proteins. A logical consequence of this is that loss-of-function mutations in G4C2-binding partners might contribute to ALS pathogenesis independently of and/or synergistically with C9ORF72 expansions. Targeted sequencing of genomic DNA encoding either RNA-binding proteins or known ALS ...

A General Neurologist's Perspective On The Urgent Need To Apply Resilience Thinking To The Prevention And Treatment Of Alzheimer's Disease, 2017 University of Massachusetts Medical School
A General Neurologist's Perspective On The Urgent Need To Apply Resilience Thinking To The Prevention And Treatment Of Alzheimer's Disease, Grazyna Pomorska, Judith K. Ockene
Open Access Articles
The goal of this article was to look at the problem of Alzheimer's disease (AD) through the lens of a socioecological resilience-thinking framework to help expand our view of the prevention and treatment of AD. This serious and complex public health problem requires a holistic systems approach. We present the view that resilience thinking, a theoretical framework that offers multidisciplinary approaches in ecology and natural resource management to solve environmental problems, can be applied to the prevention and treatment of AD. Resilience thinking explains a natural process that occurs in all complex systems in response to stressful challenges. The ...
Medical Therapies For Motor Symptoms In Parkinson’S Disease, 2017 Marshall University Joan C. Edwards School of Medicine
Medical Therapies For Motor Symptoms In Parkinson’S Disease, Conrad Musey, Vikram Shivkumar
Marshall Journal of Medicine
Parkinson’s Disease is the second most common neurodegenerative disorder in the aging population. It is associated with progressive loss of nigrostriatal dopaminergic neurons. Parkinsonism is a clinical syndrome that consists of motor and non-motor symptoms. It has been well described that many if not all of these deficits are associated with abnormalities related to the neurotransmitter Dopamine. This review is intended for primary care physicians who often establish the diagnosis and initiate Parkinson’s treatments. One challenge faced by the primary care physician is to decide the appropriate medication and starting dose. Often medications are used at very low ...

Open Access Articles
BACKGROUND: Rett syndrome (RTT) is an X-linked neurodevelopmental disorder caused by mutations in the transcriptional regulator MeCP2. Much of our understanding of MeCP2 function is derived from transcriptomic studies with the general assumption that alterations in the transcriptome correlate with proteomic changes. Advances in mass spectrometry-based proteomics have facilitated recent interest in the examination of global protein expression to better understand the biology between transcriptional and translational regulation.
METHODS: We therefore performed the first comprehensive transcriptome-proteome comparison in a RTT mouse model to elucidate RTT pathophysiology, identify potential therapeutic targets, and further our understanding of MeCP2 function. The whole cortex ...

Background: Neuroinflammation in the brain consequent to activation of microglia is viewed as an important component of Alzheimer’s disease (AD) pathology. Amyloid beta (Aβ) protein is known to activate microglia and unleash an inflammatory cascade that eventually results in neuronal dysfunction and death. In this study, we sought to identify the presence of amylin receptors on human fetal and murine microglia and determine whether Aβ activation of the inflammasome complex and subsequent release of cytokines is mediated through these receptors.
Methods: The presence of dimeric components of the amylin receptor (calcitonin receptor and receptor activity modifying protein 3) were ...

The huntingtin gene has two mRNA isoforms that differ in their 3' UTR length. The relationship of these isoforms with Huntington's disease is not established. We provide evidence that the abundance of huntingtin 3' UTR isoforms differs between patient and control neural stem cells, fibroblasts, motor cortex, and cerebellum. Huntingtin 3' UTR isoforms, including a mid-3' UTR isoform, have different localizations, half-lives, polyA tail lengths, microRNA sites, and RNA-binding protein sites. Isoform shifts in Huntington's disease motor cortex are not limited to huntingtin; 11% of alternatively polyadenylated genes change the abundance of their 3' UTR isoforms. Altered expression ...
