Male Determining Gene Nix May Bring An End To Transmission Of Diseases Through Mosquitoes, Mohammed Mahdi

Thinking Matters Symposium Archive

Female mosquitoes take blood from humans to gain protein needed to produce eggs, and in the process they can transmit viruses, such as Zika, Dengue, and chikungunya, or parasites, such as malaria. Male mosquitoes do not transmit diseases. This literature review will examine what is known about how sex is determined in mosquitoes and how this can be used to manipulate the females that spread diseases to humans. Using CRISPR Cas9, the lab of Zhijian Tu removed the Nix gene from mosquito embryos; all of these were feminized. Ectopic overexpression of Nix gene product in mosquito embryos caused even genetically …

Investigating The Role Of Free Radicals In Huntington's Disease Using Drosophila Melanogaster, Jennifer Libov

Honors Program: Senior Projects (Public)

During normal cell metabolism, reactive oxygen species (ROS) are produced as a byproduct of oxidative phosphorylation. ROS are utilized in the cell as a signaling molecule and can be maintained at healthy levels by cellular antioxidants. However, when the cell experiences oxidative stress due to environmental or genetic conditions, levels of ROS can exceed healthy levels and inhibit necessary life functions by damaging biomolecules and cellular structures. This loss of function can lead to physiological decline and neurodegeneration, such as in diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and, potentially, Huntington’s disease. The following experiments use the model genetic organism …

Innovation And Competition In Advanced Therapy Medicinal Products, Enrique Seoane-Vazquez, Vaishali Shukla, Rosa Rodriguez-Monguio

Pharmacy Faculty Articles and Research

"Advanced therapy medicinal products (ATMPs), including gene therapy, cell therapy, and tissue engineering products, represent a paradigm shift in health care as they have great potential for preventing and treating many diseases (Food and Drug Administration (FDA), 2013). By way of example, only 367 (8.0%) of the 4,603 rare diseases and conditions listed by the NIH Genetic and Rare Diseases Information Center had at least one FDA-approved drug therapy in early 2018. An estimated 3,038 (66.0%) of those rare diseases and conditions are congenital and genetic diseases that could potentially be treated by gene therapy. There are already ATMPs under …

The Master Synaptic Regulator: Activity Regulated Cytoskeleton Associated Protein, Arc, In Normal Aging And Diseases With Cognitive Impairment, Amber Khan

Dissertations, Theses, and Capstone Projects

Alzheimer’s disease (AD) is a progressive neurodegenerative disease with complex underlying pathogenic mechanisms. Epidemiological studies have forecasted that in the next 3 decades, the number of AD cases will rise to epidemic proportions with enormous medical, emotional and financial burdens impacting individuals affected and society. Among many risk factors for AD, advancing age is clearly essential and necessary. Revelation of molecular changes in synaptic activities leading to the prodromal, mild cognitive impairment (MCI) stage may help illuminate the course of pathogenic progression and its cause-effect relationship with various targets thereby enabling target-driven disease-modifying therapeutic agents for AD.

Green Tea Extract, Epigallocatechin Gallate, Protect Against Methamphetamine-Induced Striatal Neurotoxicity In Mice, Allen L. Pan

Dissertations, Theses, and Capstone Projects

Methamphetamine (METH) is a strong psychostimulant and its exposure can lead to serious neurological complications. METH-induced neuronal injury is the result of a complex interplay of different factors including dopamine (DA) overflow, oxidative stress and neuroinflammation. Although the mechanisms of METH-induced neurotoxicity have been extensively studied, there is still no effective therapeutic treatment. Therefore, it is essential to study potential drug candidates that can treat METH-induced neurotoxicity. Green tea extract, epigallocatechin gallate (EGCG), has emerged as a neuroprotective agent that can protect against several neurodegenerative diseases such as Alzheimer’s and Parkinson’s diseases. Recently, our lab has shown that EGCG prevents …

Ck2 Negatively Regulates 5-Ht4 Receptor Signaling In The Prefrontal Cortex And Mediates Depression-Like Behaviors, Julia Castello Saval

Dissertations, Theses, and Capstone Projects

The serotonergic system has been the major candidate in the pathophysiology of mood related disorders such as anxiety and major depressive disorder (MDD). Unfortunately, current antidepressant drugs are ineffective in 50% of the population and require chronic administration for a period of 3-6 weeks before the onset of therapeutic response. 5-HT4 receptor (5-HT₄R) agonists have emerged as potential candidates for fast antidepressant action, since an antidepressant response can be achieved after 3 days of pharmacological administration in rodents.

This dissertation aims to investigate the role of casein kinase 2 (CK2) as a regulator of 5-HT₄R expression …

The Promises And Challenges Of Erythropoietin For Treatment Of Alzheimer's Disease, Jiahong Sun, Jan Michelle Martin, Victoria Vanderpoel, Rachita K. Sumbria

Pharmacy Faculty Articles and Research

Alzheimer’s disease (AD) is the most prevalent neurodegenerative disorder in the world, and intracellular neurofibrillary tangles and extracellular amyloid-beta protein deposits represent the major pathological hallmarks of the disease. Currently available treatments provide some symptomatic relief but fail to modify primary pathological processes that underlie the disease. Erythropoietin (EPO), a hematopoietic growth factor, acts primarily to stimulate erythroid cell production, and is clinically used to treat anemia. EPO has evolved as a therapeutic agent for neurodegeneration and has improved neurological outcomes and AD pathology in rodents. However, penetration of the blood–brain barrier (BBB) and negative hematopoietic effects are the two …

Ray, Siyaram Pandey

Touro College of Pharmacy (New York) Publications and Research

Neurons consume the highest amount of oxygen, depend on oxidative metabolism for energy, and survive for the lifetime of an individual. Therefore, neurons are vulnerable to death caused by oxidative-stress, accumulation of damaged and dysfunctional proteins and organelles. There is an exponential increase in the number of patients diagnosed with neurodegenerative diseases such as Alzheimer’s (AD) as the number of elderly increases exponentially. Development of AD pathology is a complex phenomenon characterized by neuronal death, accumulation of extracellular amyloid-β plaques and neurofibrillary tangles, and most importantly loss of memory and cognition. These pathologies are most likely caused by mechanisms including …

Toxic Environmental Risk Factors For Alzheimer's Disease: A Systematic Review, Oluwaseyi Olayinka, Olaniyi O. Olayinka, Brook T. Alemu, Muge Akpinar-Elci, George T. Grossberg

Community & Environmental Health Faculty Publications

There is growing evidence of a possible association between toxic environmental factors and Alzheimer’s disease (AD), a disabling neurodegenerative condition with no known cause. Previous reviews of toxic environmental factors for AD either focused on occupational exposures or used a non-systematic methodology. The objective of this systematic review is to assess the evidence on the link between AD and exposure to a variety of toxic environmental risk factors beyond the work environment. Structured database search was used to identify relevant studies. Twenty-nine eligible studies examining the effect of various toxic environmental agents including electromagnetic fields, solvents, pesticides, toxic metals, and …

A Meta-Analysis Of Neuromyelitis Optica Epidemiology In Latin American Nations, Brittany M. Zengotita

Honors Undergraduate Theses

Neuromyelitis Optica (NMO) is a rare, autoimmune, neurodegenerative disease selectively affecting the optic nerves and spinal cord. Relapsing NMO is nine times more prevalent in women than in men and approximately one-quarter of NMO patients have symptoms of another autoimmune disorder (National Institute of Health, 2019). NMO has not been linked to any genetic mutations and the cause of the disorder is unknown beyond the general understanding that the body produces anti-aquaporin-4 antibodies (AQP4) which mistakenly attack cells in the nervous system. NMO affects roughly one percent of that of Multiple Sclerosis (4000-8000 patients total) in the United States, but …

Journey With Autism: Successful Educational And Social Interventions From A Single Case Study, Kwame M. De Jonge-Moore

Dissertations

Problem

Statistics indicate that Autism Spectrum Disorder (ASD) is on the increase in America and worldwide (Xu, Strathearn, Liu, & Bao, 2018; Baio et al., 2018). Autism spectrum disorder can impair an individual’s ability to engage in neurotypical behavior, which has the potential to increase their vulnerability to being shunned and bullied. This makes autism a major societal concern with significant costs to the individual, their family, private/public health insurance, state financial aid programs, and to the nation. This present study was undertaken to determine, in the opinions of those connected to the case, whether the interventions engaged in this …

Mechanisms Of Trinucleotide Repeat Instability During Dna Synthesis, Kara Y. Chan

Theses and Dissertations--Toxicology and Cancer Biology

Genomic instability, in the form of gene mutations, insertions/deletions, and gene amplifications, is one of the hallmarks in many types of cancers and other inheritable genetic disorders. Trinucleotide repeat (TNR) disorders, such as Huntington’s disease (HD) and Myotonic dystrophy (DM) can be inherited and repeats may be extended through subsequent generations. However, it is not clear how the CAG repeats expand through generations in HD. Two possible repeat expansion mechanisms include: 1) polymerase mediated repeat extension; 2) persistent TNR hairpin structure formation persisting in the genome resulting in expansion after subsequent cell division. Recent in vitro studies suggested that a …

Investigating The Role Of Neuronal Aging In Fragile X-Associated Tremor/Ataxia Syndrome, Katlin Marie Hencak

Honors Undergraduate Theses

Fragile X-associated tremor/ataxia syndrome (FXTAS) is an X-linked late-onset neurodegenerative disorder caused by a noncoding trinucleotide repeat expansion in the FMR1 gene. This gene produces fragile x mental retardation protein (FMRP), an RNA binding protein whose targets are involved in brain development and synaptic plasticity. One of the proposed mechanisms of FXTAS pathogenesis is an RNA gain-of-function in which the repeat expansion causes toxic mRNA that sequesters important proteins in the cell, interfering with their functions. Another suggested method of pathogenesis is through a mutant protein called FMRpolyG. This protein results from repeat-associated non-AUG (RAN) translation, in which the expanded …

Autologous Peripheral Nerve Grafts To The Brain For The Treatment Of Parkinson's Disease, Andrew Welleford

Theses and Dissertations--Neuroscience

Parkinson’s disease (PD) is a disorder of the nervous system that causes problems with movement (motor symptoms) as well as other problems such as mood disorders, cognitive changes, sleep disorders, constipation, pain, and other non-motor symptoms. The severity of PD symptoms worsens over time as the disease progresses, and while there are treatments for the motor and some non-motor symptoms there is no known cure for PD. Thus there is a high demand for therapies to slow the progressive neurodegeneration observed in PD. Two clinical trials at the University of Kentucky College of Medicine (NCT02369003, NCT01833364) are currently underway that …

Understanding The Contributions Of Alzheimer’S Disease & Cardiovascular Risks To Cerebral Small Vessel Disease Manifest As White Matter Hyperintensities On Magnetic Resonance Imaging (Mri), Omar M. Al-Janabi

Theses and Dissertations--Clinical and Translational Science

Introduction: Alzheimer’s Diseases (AD) & cerebral small vessel disease associated with cardiovascular risk factors (cSVD) frequently coexist, differentially affecting both imaging and clinical features associated with aging and dementia. We hypothesized that Magnetic Resonance Imaging (MRI) can be used in novel ways to identify relative contributions of AD & cardiovascular risks to cSVD and brain atrophy, generating new biomarkers & insights into mixed disease states associated with cognitive decline and dementia.

Methods: Three experiments were conducted to address the overarching hypothesis. First, we visually rated the clinical MRI of 325 participants from a community-based cross-sectional sample to elucidate the relative …
