Nebraska Center for Virology: Faculty Publications

SARS-CoV-2 is a novel coronavirus that causes a potentially fatal respiratory disease known as coronavirus disease (COVID-19) and is responsible for the ongoing pandemic with increasing mortality. Understanding the host-virus interaction involved in SARS-CoV-2 pathophysiology will enhance our understanding of the mechanistic basis of COVID-19 infection. The characterization of post-transcriptional gene regulatory networks, particularly pre-mRNA splicing, and the identification and characterization of host proteins interacting with the 5' and 3'UTRs of SARS-CoV-2 will improve our understanding of posttranscriptional gene regulation during SARS-CoV-2 pathogenesis. Here, we demonstrate that either SARS-CoV-2 infection or exogenous overexpression of the 5' and 3’UTRs of the …

Accuracy Of Therapeutic Drug Monitoring In Vancomycin And The Pharmacist Role: A Retrospective Case-Series, Kateryna Parkhomenko

Senior Theses

Vancomycin is a mainstay of therapy for treating virulent and resistant infections, especially methicillin-resistant Staphylococcus aureus (MRSA). However, vancomycin requires therapeutic drug monitoring (TDM) for optimal dosing and treatment. This requires pharmacists to calculate a dosing regimen that correlates to appropriate goal vancomycin concentrations in the blood. Dosing vancomycin can be difficult, as it varies on a patient’s weight, renal function, age, etc. Doses may have to be adjusted in response to out-of-range concentrations, which requires further pharmacy calculations. Inaccurate dosing poses a risk to patient safety and places a resource and time burden on pharmacists. If vancomycin dosing methods …

The Power And Challenge Of Lipid (A)Symmetry Across The Membrane And Cell, Mikhail Bogdanov

Journal Articles

Membrane asymmetry means that the two sides of membrane are structurally, physically and functionally different. Membrane asymmetry is largely related to the lipid sidedness and particularly to compositional (lipid head and acyl group) and physical (lipid packing order, charge, hydration and H-bonding interactions) differences in the inner and outer leaflets of lipid bilayer. Chemically, structurally and conformationally different non-covalent bound lipid molecules are physically fluid and deformable and enable to interact dynamically to form transient arrangements with asymmetry both perpendicular and parallel to the plane of the lipid bilayer. Although biological membranes are almost universally asymmetric however the asymmetry is …

Renovating A Double Fence With Or Without Notifying The Next Door And Across The Street Neighbors: Why The Biogenic Cytoplasmic Membrane Of Gram-Negative Bacteria Display Asymmetry?, Mikhail Bogdanov

Journal Articles

The complex two-membrane organization of the envelope of Gram-negative bacteria imposes an unique biosynthetic and topological constraints that can affect translocation of lipids and proteins synthesized on the cytoplasm facing leaflet of the cytoplasmic (inner) membrane (IM), across the IM and between the IM and outer membrane (OM). Balanced growth of two membranes and continuous loss of phospholipids in the periplasmic leaflet of the IM as metabolic precursors for envelope components and for translocation to the OM requires a constant supply of phospholipids in the IM cytosolic leaflet. At present we have no explanation as to why the biogenic E. …

Pamam- Cyclodextrin Conjugate Upregulates Brain-Derived Neurotropic Factor In Arpe-19 Cells, Gopika Ashokan

USF Tampa Graduate Theses and Dissertations

Background: Traumatic Brain Injury (TBI) is a major contributor to death and disability due to motorvehicle accidents, sports, physical abuse, and battlefield injuries. The primary insult to the brain leads to inflammation, vascular dysfunction, and oxidative stress in the brain as well as in the eye. This leads to loss of Retinal Ganglion Cells (RGCs) and downregulation of Brain derived Neurotopic Factor (BDNF). BDNF is a neurotrophic factor that binds to Tropomyosin Receptor Kinase B (TrkB) receptor to promote cell growth, survival, and differentiation. Current treatment strategies do not promote neuronal regeneration. Therefore, novel treatments are needed to restore vision …

Conference Presentation Abstracts

OBJECTIVES: Approximately 60,000 lower extremity amputations (LEA) are performed annually in the United States and 38%-55% of those individuals are fitted for a prosthesis. The average price of a lower extremity prosthetic device alone is $10,000, not including the associated costs of physical therapy and prosthetic fitting and maintenance. The most important factor influencing quality of life for individuals who have undergone LEA is the ability to ambulate with a prosthesis. The goal of our study was to investigate characteristics of individuals who abandon use of their prosthesis following LEA and identify any modifiable factors that may increase long-term successful …

Histone Deacetylase 8 Is A Novel Therapeutic Target For Mantle Cell Lymphoma And Preserves Natural Killer Cell Cytotoxic Function, January M. Watters

USF Tampa Graduate Theses and Dissertations

This study demonstrates for the first time that HDAC8 function is critical for MCL survival, and abrogating its activity in human primary NK cells does not interfere with NK IgG antibody directed ADCC therapies ex vivo. Human NK cells, isolated from healthy donors, are highly resistant to HDAC8 inhibitor treatment with PCI-34051. Even at the highest concentration, 20uM, no toxicity was observed. Conversely, MCL cell lines representative of the aggressive MCL subtype, classical MCL, were especially sensitive to PCI-34051, an HDAC8 selective inhibitor, treatment. Blocking HDAC8 activity and/or abrogating expression through shRNA silencing induced significant DNA damage, hyperacetylation of SMC3, …

Potassium-Selective Channelrhodopsins, Elena G Govorunova, Oleg A Sineshchekov, John L Spudich

Journal Articles

Since their discovery 21 years ago, channelrhodopsins have come of age and have become indispensable tools for optogenetic control of excitable cells such as neurons and myocytes. Potential therapeutic utility of channelrhodopsins has been proven by partial vision restoration in a human patient. Previously known channelrhodopsins are either proton channels, non-selective cation channels almost equally permeable to Na+ and K+ besides protons, or anion channels. Two years ago, we discovered a group of channelrhodopsins that exhibit over an order of magnitude higher selectivity for K+ than for Na+. These proteins, known as “kalium channelrhodopsins” or KCRs, lack the canonical tetrameric …

Apkcs Role In Neuroblastoma Cell Signaling Cascades And Implications Of Apkcs Inhibitors As Potential Therapeutics, Sloan Breedy

USF Tampa Graduate Theses and Dissertations

Neuroblastoma (NB) is a cancer that develops in the neuroblasts. It is the most common cancer in children under the age of 1 year, accounting for approximately 6% of all cancers. The prognosis of NB is linked to both age and degree of cell differentiation. This results in a range of survival rates for patients, with outcomes ranging from recurrence and mortality to high survival rates and tumor regression. Our previous work indicated that PKC-ι promotes cell proliferation in NB cells through the PKC-ι/Cdk7/Cdk2 cascade. We report on two atypical protein kinase inhibitors as potential therapeutic candidates against BE(2)-C and …

Alharbi, Amani A. R. Filimban, Mazen S. Alseghayer, Abdulaziz M. Almaneea, Meshari Ahmed Alhadlaq, Jumaa Ayubu, Addisu D. Teklemariam

Nebraska Center for Virology: Faculty Publications

The consumer demand for fresh produce (vegetables and fruits) has considerably increased since the 1980s for more nutritious foods and healthier life practices, particularly in developed countries. Currently, several foodborne outbreaks have been linked to fresh produce. The global rise in fresh produce associated with human infections may be due to the use of wastewater or any contaminated water for the cultivation of fruits and vegetables, the firm attachment of the foodborne pathogens on the plant surface, and the internalization of these agents deep inside the tissue of the plant, poor disinfection practices and human consumption of raw fresh produce. …

Mglu5 Inhibition In The Basolateral Amygdala Prevents Estrous Cycle-Dependent Changes In Cue-Induced Cocaine Seeking, Claire M. Corbett, Emily N. D. Miller, Jessica A. Loweth

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship

Drug associated cues are a common relapse trigger for individuals recovering from cocaine use disorder. Sex and ovarian hormones influence patterns of cocaine use and relapse vulnerability, with studies indicating that females show increased cue-induced craving and relapse vulnerability compared to males. In a rodent model of cocaine craving and relapse vulnerability, cue-induced cocaine seeking behavior following weeks of withdrawal from extended-access cocaine self-administration is higher in females in the estrus stage of the reproductive (estrous) cycle (Estrus Females) compared to both Males and females in all other stages (Non-Estrus Females). However, the neuronal substrates and cellular mechanisms underlying these …
