Evaluating Alternate Motor Pathway Changes Following A Stroke, Rama N. Shaath, Marylu Cabello, Daniel Salinas, Michael R. Dobbs, Kelsey Potter-Baker

Research Symposium

Background: Stroke is the fifth cause of death in the United States. Not only is stroke a leading cause of death but it is also a leading cause of long-term disability in the United States. Long-term impairments after stroke include gait instability, upper limb paralysis, sensory deficits, pain, depression, and cognitive impairments. The most common impairment is motor paresis of the upper and lower limb. Rehabilitation remains the gold standard in addressing motor paresis with the goal of enabling subjects to regain independence and daily living skills. Strokes often impact the crossed lateral corticospinal tract, by damaging the tract …

Contribution Of 24-H Blood Pressure Variability To Dementia-Related Disorders In Hispanics, Nura Salhadar, Kristina Vatcheva, Silvia Mejia-Arango Dr., Luis J. Mena, Ney Alliey-Rodriguez, Carlos A. Chavez, Ciro A. Goana, Egle Silva, Gustavo Calmon, Rosa P. Mavarez, Joseph H. Lee, Joseph D. Terwilliger, Jesus D. Melgarejo, Gladys E. Maestre

Research Symposium

Introduction: As the number of people living with dementia is increasing at alarming rates worldwide, there is an urgent need to understand the physiopathology of dementia syndromes. Among the most important preventable risk factors, treatment of vascular risk factors such as high blood pressure (BP) decreases the risk of Alzheimer’s disease and related dementias (ADRD). Recent evidence suggests that examining BP variability provides additional physiopathological and predictive information above the mean BP level. However, studies examining the relationship between 24-h BP variability and ADRD are limited, and evidence of the association with dementia has not been documented yet. Therefore, we …

The Influence Of Concussions On Fracture Severity: A Retrospective Chart Review, Hunter M. Butler, Blake Martin, Jared Hensley, Russell Wiggins, Kevin Garcia Valdez, Chloe Harris, Kelsey Potter-Baker

Research Symposium

Background: Since 2005, there has been an 87% increase in concussions in high school sports. Concussions and concussion-like events are associated with a myriad of pathologies, but recently, clinical research has suggested that such events can lead to hypoparathyroidism and decreased bone mass. Specifically, research has suggested that following a concussion-like event, blood calcium may be reduced and influence bone mass and future healing from bone insults. However, a specific correlation between the loss of available blood calcium and severity of bone fractures in previously concussed individuals has yet to be identified. In this study, we will explore the clinical …

Neurological Comorbidities In Hispanic Skin Cancer Patients In South Texas: A Five-Year Retrospective Study, Jared Hensley, Russell Wiggins, Blake Martin, Hunter M. Butler, Kevin Garcia Valdez, Chloe Harris, Kelsey Potter-Baker

Research Symposium

Background: Skin cancer is highly prevalent in the South Texas region due to a combination of increased UVB exposure, occupational hazards, and lack of access to preventative screening. Unfortunately, several studies have suggested that skin cancer diagnosis may be linked with an increased risk of neurodegenerative conditions, such as Alzheimer’s Disease. For example, it was recently suggested that amyloid beta plaques may have a role in melanoma metastasis. Here, we seek to evaluate the role of skin cancer incidence and the degree and severity of neurological comorbidities, with a particular focus on the Hispanic patient population. We anticipate that a …

A Fork In The Road: Uncovering The Impact Of Industrial Animal Agriculture On The Physical Health Of Communities Of Color, Mariana Zepeda

Population Health Research Brief Series

Nearly all (99%) farmed animals in the U.S. come from Concentrated Animal Feeding Operations (CAFOs). CAFOs are industrial agriculture facilities defined by the U.S. Environmental Protection Agency (EPA) as operations where animals are raised in confinement and meet animal size and waste material thresholds. Communities located near CAFOs, which tend to have high shares of low-income and racial/ethnic minority residents, are at risk of exposure to CAFO-related air and water pollutants. This brief summarizes the health risks for communities located near CAFOs. Additionally, it calls for government regulations that improve transparency, management, and consumer empowerment.

Germline Structural Variation Globally Impacts The Cancer Transcriptome Including Disease-Relevant Genes, Fengju Chen, Yiqun Zhang, Fritz J Sedlazeck, Chad J Creighton

Faculty, Staff and Students Publications

Germline variation and somatic alterations contribute to the molecular profile of cancers. We combine RNA with whole genome sequencing across 1,218 cancer patients to determine the extent germline structural variants (SVs) impact expression of nearby genes. For hundreds of genes, recurrent and common germline SV breakpoints within 100 kb associate with increased or decreased expression in tumors spanning various tissues of origin. A significant fraction of germline SV expression associations involves duplication of intergenic enhancers or 3' UTR disruption. Genes altered by both somatic and germline SVs include ATRX and CEBPA. Genes essential in cancer cell lines include BARD1 and …

Establishment Of Murine Pregnancy Requires The Promyelocytic Leukemia Zinc Finger Transcription Factor, Lan Hai, Vineet K Maurya, Francesco J Demayo, John P Lydon

Faculty, Staff and Students Publications

Using an established human primary cell culture model, we previously demonstrated that the promyelocytic leukemia zinc finger (PLZF) transcription factor is a direct target of the progesterone receptor (PGR) and is essential for progestin-dependent decidualization of human endometrial stromal cells (HESCs). These in vitro findings were supported by immunohistochemical analysis of human endometrial tissue biopsies, which showed that the strongest immunoreactivity for endometrial PLZF is detected during the progesterone (P4)-dominant secretory phase of the menstrual cycle. While these human studies provided critical clinical support for the important role of PLZF in P4-dependent HESC decidualization, functional validation in vivo was not …

Predation Without Direction Selectivity, Jenna Krizan, Xiayingfang Song, Michael J Fitzpatrick, Ning Shen, Florentina Soto, Daniel Kerschensteiner

2020-Current year OA Pubs

Across the animal kingdom, visual predation relies on motion-sensing neurons in the superior colliculus (SC) and its orthologs. These neurons exhibit complex stimulus preferences, including direction selectivity, which is thought to be critical for tracking the unpredictable escape routes of prey. The source of direction selectivity in the SC is contested, and its contributions to predation have not been tested experimentally. Here, we use type-specific cell removal to show that narrow-field (NF) neurons in the mouse SC guide predation. In vivo recordings demonstrate that direction-selective responses of NF cells are independent of recently reported stimulus-edge effects. Monosynaptic retrograde tracing reveals …

Two Dot1 Enzymes Cooperatively Mediate Efficient Ubiquitin-Independent Histone H3 Lysine 76 Tri-Methylation In Kinetoplastids, Victoria S Frisbie, Hideharu Hashimoto, Yixuan Xie, Francisca N De Luna Vitorino, Josue Baeza, Tam Nguyen, Zhangerjiao Yuan, Janna Kiselar, Benjamin A Garcia, Erik W Debler

2020-Current year OA Pubs

In higher eukaryotes, a single DOT1 histone H3 lysine 79 (H3K79) methyltransferase processively produces H3K79me2/me3 through histone H2B mono-ubiquitin interaction, while the kinetoplastid Trypanosoma brucei di-methyltransferase DOT1A and tri-methyltransferase DOT1B efficiently methylate the homologous H3K76 without H2B mono-ubiquitination. Based on structural and biochemical analyses of DOT1A, we identify key residues in the methyltransferase motifs VI and X for efficient ubiquitin-independent H3K76 methylation in kinetoplastids. Substitution of a basic to an acidic residue within motif VI (Gx
