Title: Survivin and Caspases Coordinate Proteolytic Cleavage of the SAGA Chromatin Modifying Complex

Elinor Harrison¹, Alejandro Damian¹, CJ Talton¹, Jelly H Soffers¹, Abudu I Bello¹, Kara M Costanzo¹, Joe Bean¹, Ryan D Mohan¹

¹Wayne State University School of Medicine

Background: The Spt Ada Gcn5 Acetyltransferase (SAGA) chromatin modifying complex is a critical regulator of gene expression. Mutation or stoichiometric imbalance of SAGA subunits leads to a spectrum of diseases in model organisms and in humans, including neurodegeneration. SAGA contributes to gene activation through coordinated …

Determining Immune Activation in a Drosophila Model of ALS

Abrielle Fretz and Ryan Insolera

Background:

ALS is a progressive neurodegenerative disease that leads to muscle weakness and death. While most cases of ALS are sporadic, around 10% of cases are inherited. Of these inherited cases, one gene found to be involved is optineurin (OPTN). Mutated OPTN induces a cycle of cellular stress and death through NF-kB, a gene regulating immune activation and cell death. This dysregulation is thought to be a contributing factor to the disease processes of ALS.

In Drosophila, mutation of OPTN’s homologous gene, Kenny, was found to …

Clinical And Imaging Correlates Of Cognitive Impairment Patterns In Early Unilateral Brain Injury Associated With Sturge-Weber Syndrome, Halah Keramane, Csaba Juhasz Md, Phd, Michael E. Behen Phd, Aimee Luat Md

Medical Student Research Symposium

Background: Sturge-Weber syndrome (SWS) is a rare neurocutaneous disease characterized by cerebral venous malformations leading to early damage of affected brain regions. Clinical symptoms include seizures, motor and cognitive impairment. Most SWS patients have unilateral brain involvement, and previous studies reveal substantial neurological plasticity in some of them. Some children with left-hemispheric damage demonstrate, paradoxically, preserved verbal functions and reduced nonverbal functions (a “crowding” effect), suggesting contralateral functional reorganization from damaged cortical regions. We evaluated the incidence as well as clinical and imaging correlates of such functional reorganization/crowding.

Methods: Forty-six patients (age: 2.5-24 years) with unilateral SWS underwent neurocognitive evaluations …

Differentiating Axonal From Demyelinating Neuropathies Using Multiparametric Quantitative Mri Of Peripheral Nerves, Jacob D. Baraz, Stephanie Xuan, Sadaf Saba, Xue Yang, Ryan Castoro, Yang Xuan, Alison Roth, Richard D. Dortch, Jun Li, Yongsheng Chen

Medical Student Research Symposium

Objectives: To develop a multiparametric quantitative MRI (qMRI) method to track pathological changes in the peripheral neuropathies.

Background: Irrespective of the causes or types of polyneuropathies, peripheral nerves are mainly afflicted by two kinds of pathologies – axonal loss and demyelination. It is critical to differentiate between the two as treatments are different for the two conditions. While nerve conduction studies (NCS) have been used to differentiate the two pathologies in the distal nerves, there are no tools to probe the pathologies in the proximal peripheral nerves. This is particularly needed when distal nerves become non-responsive in NCS.

Methods: We …

Meta-Analysis Of 175 Patients With Covid-19 And Seizures, Status Epilepticus, Or Cortical Myoclonus: An Individual Patient Data Analysis, Aditi Kappagantu Bs, Helena A. Brantz Ms, Amman Bhasin Ba, Cristina Jageka Bs, Rooqash Ali Md, Izzy Saef Md, Brittany M. Stopa Mph, Ayaz Khawaja Md

Medical Student Research Symposium

Objective

To characterize management and outcomes of seizures, status epilepticus, and cortical myoclonus in COVID-19, with individual patient data analysis of published literature.

Methods

Systematic literature review was conducted in accordance with PRISMA guidelines. Criteria included new-onset seizures, status epilepticus, and/or cortical myoclonus with concomitant COVID-19. COVID-19 severity was dichotomized into mild and severe cases. Good outcome was defined as discharge without severe deficits, and/or return to baseline.

Results

A total of 105 studies reporting 176 patients (male 56.3%;mean age 47.8,SD 25.6) were included. Status epilepticus occurred in 47 patients (26.7%) and myoclonus in 41 (23.3%). Severe COVID-19 occurred in …

Characterization Of Abin-1 In The Traumatically Injured Brain, Aaron Orellana, Alana C. Conti

Medical Student Research Symposium

Traumatic brain injury (TBI) is associated with chronic pain and persistent neuroinflammation. Opioids are often prescribed in order to relieve pain symptoms, but recent evidence suggests that their use negatively impacts the neuropathology of TBI leading to behavioral impairments and exacerbated neuroinflammation. The de-ubiquinating enzyme tumor necrosis factor alpha-induced protein (TNFAIP)3 or A20, inhibits the inflammatory signaling transcription factor nuclear factor (NF)-kB leading to attenuation of the inflammatory response. A20-binding inhibitor of nuclear factor kB (ABIN-1), which physically interacts with A20, also plays a role in the inhibition of NF-kB and is poorly researched in the central nervous system (CNS). …

Management Of Childhood Migraine By Headache Specialist Versus Non-Headache Specialists, Kelly Valentini, Radhika Gutta, Gunjanpreet Kaur, Ahmad Farooqi, Lalitha Sivaswamy

Medical Student Research Symposium

This study aims to compare the management practices of a headache specialist with non-headache specialists in the treatment of pediatric migraine. The use of appropriate rescue medications and prophylactic agents, application of neuro-imaging, and short-term outcomes are compared in children treated by the two groups of physicians. A retrospective cohort study was conducted utilizing the electronic medical records of children 3-18 years of age with migraine, who were evaluated at a tertiary care children’s hospital from 2016-2018. Of the 849 patients that met the study criteria, 469 were classified as having chronic migraine or high-frequency episodic migraine and were followed …
