Paclitaxel Enhances Oncolytic Potential Of Herpes Simplex Virus Type-1 In Cancer Cells, Misagh Naderi
Paclitaxel Enhances Oncolytic Potential Of Herpes Simplex Virus Type-1 In Cancer Cells, Misagh Naderi
LSU Master's Theses
Taxanes are spindle poisons that bind to and stabilize microtubules resulting in mitotic arrest. Herpes simplex Typ-1 (HSV-1) virions utilize the microtubular network for intracellular transport during both virus entry and virus egress from infected cells. It has been reported previously that taxanes may synergize with oncolytic herpes simplex viruses in the treatment of experimental prostate and breast tumors in mice. Other reports have indicated that taxanes may inhibit viral replication in infected cells. In this study the previously characterized Oncolytic Herpes Simplex Virus type 1 (OSVP), which was constructed in Kousoulas lab was used in conjugation with paclitaxel (taxol) …

Central nervous system (CNS) involvement occurs in 5 to 10% of individuals with disseminated histoplasmosis. Most experience has been derived from small single center case series, or case report literature reviews. Therefore, a larger study of central nervous system (CNS) histoplasmosis is needed in order to guide the approach to diagnosis, and treatment.
A convenience sample of 77 patients with histoplasmosis infection of the CNS was evaluated. Data was collected that focused on recognition of infection, diagnostic techniques, and outcomes of treatment.
Twenty nine percent of patients were not immunosuppressed. Histoplasma antigen, or anti-Histoplasma antibodies were detected in the …

Doctor of Nursing Practice
The purpose of this quality improvement project was to increase human papillomavirus vaccination series initiation rates among indigent women, ages 19-26, at a clinic in South Texas. The human papillomavirus is a sexually transmitted infection that has been associated with multiple types of cancers. Each year, approximately 6.2 million cases of the human papillomavirus infection are diagnosed; as many as 75% of all new infections occur among females 18-26 years of age. The human papillomavirus vaccination has a high efficacy in regards to cancer prevention, preventing as many as 76% of cancers with only one dose. The project included educating …
Finding Human Proteins That Bind To A Lassa Virus Protein, Maria Alejandra Pardo Ruge, Veronica J. Heintz, Douglas J. Lacount
Finding Human Proteins That Bind To A Lassa Virus Protein, Maria Alejandra Pardo Ruge, Veronica J. Heintz, Douglas J. Lacount
The Summer Undergraduate Research Fellowship (SURF) Symposium
Viral hemorrhagic fevers are severe illnesses caused by many different viruses. Lassa Virus is one of these important pathogens in Western Africa, causing hemorrhagic fever and eventually death without early medical treatment. There is no vaccine and there is little information on host-pathogen interactions. Therefore, the interaction between viral proteins and host targets is useful to understand Lassa virus’s lifecycle and pathology, and to develop ways to prevent infection. In this project, we study the nucleoprotein of Lassa virus (NP), which has been reported to have anti-interferon (IFN) activity through elimination of double stranded RNA (dsRNA). These features could be …
Induction And Suppression Of Antiviral Rna Silencing By Tomato Spotted Wilt Virus, Sergio M. Gabriel Peralta
Induction And Suppression Of Antiviral Rna Silencing By Tomato Spotted Wilt Virus, Sergio M. Gabriel Peralta
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Tomato spotted wilt virus (TSWV) is an emerging pathogen with wide host range and one of the most important viruses of plants. Information regarding processing of negative single stranded RNA viruses such as TSWV in the RNA silencing pathway remains limited. In nature TSWV is only transmitted by thrips as vectors and since infection occurs in both thrips and plants, an experimental system to transmit using thrips and the detection of TSWV were established. In order to understand the processing of TSWV in the RNA silencing pathway, Arabidopsis thaliana as a model plant was used in the genetic analysis against …

A total of 2169 cloacal and 2191 oropharyngeal swabs as well as 1725 sera samples were collected from live birds including duck and chicken in different locations in Bangladesh between the years of 2013 and 2014. Samples were tested using virus isolation, serological tests and molecular methods of RT-PCR. …
Assessment Of The Zoonotic Potential Of A Novel Bovine Influenza Virus, Laura Evelyn Eckard
Assessment Of The Zoonotic Potential Of A Novel Bovine Influenza Virus, Laura Evelyn Eckard
Theses and Dissertations (ETD)
A novel orthomyxovirus was recently identified from pigs, with subsequent work suggesting the natural reservoir being bovine populations. The virus had genome characteristics most similar to influenza C viruses (ICV) but, due to the extent of sequence divergence, was proposed as a new genus, influenza D virus (IDV). Current literature on IDV has largely focused on the agricultural significance of the virus and provided evidence for the agricultural impact via observation of widespread prevalence and pathology in laboratory infected cattle. However, only one study, which identified 1.3% seroprevalence in a small cohort, has addressed the zoonotic potential of IDV to …
The Impact Of Urbanization On Mosquito-Borne Viruses, Nikhita Puthuveetil
The Impact Of Urbanization On Mosquito-Borne Viruses, Nikhita Puthuveetil
Undergraduate Research Posters
Mosquito-borne diseases such as yellow fever, dengue, and West Nile are rapidly emerging across the globe. Their emergence is often aided by the growth of their vector population, or the organisms that transmit the virus to the host. Urbanization and land use often destroys the habitat of the virus and its vector. However, the virus and its vector often survive despite the changes to its environment. The goal of this paper is to find out exactly how urbanization and changes in land use affect mosquito-borne viruses and how these viruses survive despite the destruction of their habitats. To understand how …

BACKGROUND: Dengue is endemic to the rural province of Kamphaeng Phet, Northern Thailand. A decade of prospective cohort studies has provided important insights into the dengue viruses and their generated disease. However, as elsewhere, spatial dynamics of the pathogen remain poorly understood. In particular, the spatial scale of transmission and the scale of clustering are poorly characterized. This information is critical for effective deployment of spatially targeted interventions and for understanding the mechanisms that drive the dispersal of the virus.
METHODOLOGY/PRINCIPAL FINDINGS: We geocoded the home locations of 4,768 confirmed dengue cases admitted to the main hospital in Kamphaeng Phet …
Structural And Functional Interactions Between Bro1 Domain Of Human Alix Protein And Nucleocapsid Packaging Rna Complex From Hiv, Scott Gross
Graduate School of Biomedical Sciences Theses and Dissertations
A virus is only as powerful as its ability to spread. Enveloped retroviruses, namely HIV-1, use exocytosis pathways that normal host cells use to release particles from the plasma membrane. The main pathways of interest in this study are the Endosomal Sorting Complex Required for Transport (ESCRT) and adjacent ALIX pathways. The ESCRT pathway is especially important for degradation of receptor/cargo complexes that form Multi-Vesicular Bodies (MVBs). Currently, there is no known therapy that targets this endosomal pathway, which would prevent the spread of the virus to other cells. The virus has adapted to jump from pathway to pathway when …
Sustained Adrenergic Signaling Promotes Cervical Cancer Progression, Nouara C. Sadaoui
Sustained Adrenergic Signaling Promotes Cervical Cancer Progression, Nouara C. Sadaoui
Dissertations & Theses (Open Access)
Background: Chronic stress and sustained adrenergic signaling are known to promote tumor progression. The underlying mechanisms behind this process are not well understood. We examined the effects of sustained adrenergic signaling on cervical cancer progression through increased expression of HPV oncogenes, E6 and E7.
Materials and Methods: ADRβ expression levels were examined in patient-derived cervical cancer samples. We used an orthotopic model of cervical cancer to investigate the effects of restraint stress on tumor growth and metastasis. We evaluated the in vivo effects of a β-blocker, propranolol, and HPV E6/E7 siRNA. In vitro, ADRβ positive cervical cancer cells were …
Enhanced Expression Of Codon Optimized Mycobacterium Avium Subsp. Paratuberculosis Antigens In Lactobacillus Salivarius, Christopher D. Johnston, John P. Bannatine, Rodney Govender, Lorraine Endersen, Daniel Pletzer, Helge Weingart, Aidan Coffey, Jim O'Mahony, Roy D. Sleator
Enhanced Expression Of Codon Optimized Mycobacterium Avium Subsp. Paratuberculosis Antigens In Lactobacillus Salivarius, Christopher D. Johnston, John P. Bannatine, Rodney Govender, Lorraine Endersen, Daniel Pletzer, Helge Weingart, Aidan Coffey, Jim O'Mahony, Roy D. Sleator
Department of Biological Sciences Publications
It is well documented that open reading frames containing high GC content show poor expression in A+T rich hosts. Specifically, G+C-rich codon usage is a limiting factor in heterologous expression of Mycobacterium avium subsp. paratuberculosis (MAP) proteins using Lactobacillus salivarius. However, re-engineering opening reading frames through synonymous substitutions can offset codon bias and greatly enhance MAP protein production in this host. In this report, we demonstrate that codon-usage manipulation of MAP2121c can enhance the heterologous expression of the major membrane protein (MMP), analogous to the form in which it is produced natively by MAP bacilli. When heterologously over-expressed, antigenic determinants …
Characterizing The Response Of Multidrug-Resistant Klebsiella Pneumoniae Species To The Application Of A Phage Cocktail, Steven Liu
Symposium
Project Summary: The application of bacteriophages to treat bacterial infections is known as phage therapy, which takes advantage of bacteriophage’s natural ability to infect and lyse bacterial hosts. Phages have been shaped by billions of years of evolution to be highly specialized deliverers of bactericidal agents to the cytoplasm of their target bacteria. Ever since discovery of bacteriophages in 1915, phage therapy was recognized as a potentially powerful tool for eliminating bacterial infections. The effectiveness of phage therapy can be increased by creating a mixture of multiple phages to target a wider variety of bacterial strains. Furthermore, phage therapy has …
Human Adenovirus E1a Binds And Retasks Cellular Hbre1, Blocking Interferon Signalling And Activating Virus Early Gene Transcription, Gregory J. Fonseca
Human Adenovirus E1a Binds And Retasks Cellular Hbre1, Blocking Interferon Signalling And Activating Virus Early Gene Transcription, Gregory J. Fonseca
Electronic Thesis and Dissertation Repository
Upon infection, human adenovirus (HAdV) must block interferon signaling and activate the expression of its early genes to reprogram the cellular environment to support virus replication. During the initial phase of infection, these processes are orchestrated by the first HAdV gene expressed during infection, early region 1A (E1A). E1A binds and appropriates components of the cellular transcriptional machinery to modulate cellular gene transcription and activate viral early genes transcription. We have identified hBre1/RNF20 as a novel target of E1A. hBre1 is an E3 ubiquitin ligase which acts with the Ube2b E2 conjugase and accessory factors RNF40 and WAC1 to monoubiquitinate …

Murine Gammaherpesvirus 68 Lana Acts On Terminal Repeat Dna To Mediate Episome Persistence, Aline C. Habison, Chantal Beauchemin, J. Pedro Simas, Edward J. Usherwood
Murine Gammaherpesvirus 68 Lana Acts On Terminal Repeat Dna To Mediate Episome Persistence, Aline C. Habison, Chantal Beauchemin, J. Pedro Simas, Edward J. Usherwood
Dartmouth Scholarship
Murine gammaherpesvirus 68 (MHV68) ORF73 (mLANA) has sequence homology to Kaposi’s sarcoma-associated herpesvirus (KSHV) latency-associated nuclear antigen (LANA). LANA acts on the KSHV terminal repeat (TR) elements to mediate KSHV episome maintenance. Disruption of mLANA expression severely reduces the ability of MHV68 to establish latent infection in mice, consistent with the possibility that mLANA mediates episome persistence. Here we assess the roles of mLANA and MHV68 TR (mTR) elements in episome persistence. mTR-associated DNA persisted as an episome in latently MHV68-infected tumor cells, demonstrating that the mTR elements can serve as a cis-acting element for MHV68 episome maintenance. In some …
Contribution Of The Membrane-Proximal Region Of The Vesicular Stomatitis Virus Glycoprotein To Host Cell Entry And Membrane Fusion, Elizabeth Lane Matheny
Contribution Of The Membrane-Proximal Region Of The Vesicular Stomatitis Virus Glycoprotein To Host Cell Entry And Membrane Fusion, Elizabeth Lane Matheny
Theses and Dissertations (ETD)
Vesicular stomatitis virus (VSV) is an enveloped, nonsegmented, negative-sense, RNA virus belonging to the Rhabdoviridae family. VSV is considered the prototypic Rhabdovirus due to its simple genetic organization, broad host cell tropism, and ability to be easily grown in cell culture. Therefore, VSV has been used as the prototype to study viral entry, transcription, replication, and assembly. Viral entry, a critical step in the lifecycle of the virus, is mediated by the outer surface protein, G and will be the focus of this dissertation.
We hypothesize that the highly conserved residues in the membrane-proximal region of VSV G protein are …

Helical Peptides Derived From Lactoferrin Bind Hepatitis C Virus Envelope Protein E2, Reem Beleid, Donna Douglas, Norman Kneteman, Kamaljit Kaur
Pharmacy Faculty Articles and Research
Hepatitis C virus is a major cause of chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma infecting more than 170 million people. Hepatitis C virus envelope 2 glycoprotein (E2) binds several cell‐surface molecules that act as receptor candidates mediating hepatitis C virus entry into hepatocytes. Peptides derived from human lactoferrin have been shown to bind hepatitis C virus‐E2 protein thereby preventing hepatitis C virus entry in cultured hepatocytes. In this study, starting from a 33‐residue human lactoferrin‐derived peptide, a number of biotin‐linked α‐peptides were synthesized and investigated for their E2 protein binding activity. E2 protein from hepatitis C virus genotype 1b …

Experimentation To Develop Procedures To Be Used In The Investigation Of The Effects Of Restriction On The Unmodified Dna Of The Bacteriophage Lamda, John Haynes
Honors Theses
The results of experimentation approximately twenty years ago with variuos bacteriophages by Ralston and Krueger16, Anderson and Felix1, Luria and Human12, and by Bertani and Weigle2 have shown that the host range of a given phage depends directly on the bacterial strain on which the phage has last propagated. This event came to be known as host-induced modification or host-controlled variation. As this phage host range is controlled by the host environment and can be altered from one generation to another it has, according to Luria, made microbiology "the last stronghold of Lamarckism" …
