Amyotrophic Lateral Sclerosis (ALS), a late-onset neurodegenerative disorder characterized by the loss of motor neurons in the central nervous system, has no known cure to-date. Disease causing mutations in human Fused in Sarcoma (FUS) leads to aggressive and juvenile onset of ALS. FUS is a well-conserved protein across different species, which plays a crucial role in regulating different aspects of RNA metabolism. Targeted misexpression of FUS in Drosophila model recapitulates several interesting phenotypes relevant to ALS including cytoplasmic mislocalization, defects at the neuromuscular junction and motor dysfunction. We screened for the genetic modifiers of human FUS-mediated neurodegenerative phenotype using molecularly ...

FIU Electronic Theses and Dissertations

Characterization of the complex cortical structure of the brain at a cellular level is a fundamental goal of neuroscience which can provide a better understanding of both normal function as well as disease state progression. Many challenges exist however when carrying out this form of analysis. Immunofluorescent staining is a key technique for revealing 3-dimensional structure, but subsequent fluorescence microscopy is limited by the quantity of simultaneous targets that can be labeled and intrinsic lateral and isotropic axial point-spread function (PSF) blurring during the imaging process in a spectral and depth-dependent manner. Even after successful staining, imaging and optical deconvolution ...

Plant Defensin Antibacterial Mode Of Action Against Pseudomonas Species, Andrew E. Sathoff, Shawn Lewenza, Deborah A. Samac

Faculty Research & Publications

Background: Though many plant defensins exhibit antibacterial activity, little is known about their antibacterial mode of action (MOA). Antimicrobial peptides with a characterized MOA induce the expression of multiple bacterial outer membrane modifications, which are required for resistance to these membrane-targeting peptides. Mini-Tn5- lux mutant strains of Pseudomonas aeruginosa with Tn insertions disrupting outer membrane protective modifications were assessed for sensitivity against plant defensin peptides. These transcriptional lux reporter strains were also evaluated for lux gene expression in response to sublethal plant defensin exposure. Also, a plant pathogen, Pseudomonas syringae pv. syringae was modified through transposon mutagenesis to create ...

Therefore, the present review is dedicated to filling this gap by describing the many different facets of the in vivo biosynthesis of nanoparticles (NPs) using living eukaryotic ...


A Genetically-Encoded Reporter For In Vivo Imaging In Deep Tissues, Nivin N. Nasri 2020 The University of Western Ontario

A Genetically-Encoded Reporter For In Vivo Imaging In Deep Tissues, Nivin N. Nasri

Electronic Thesis and Dissertation Repository

Introduction. The ability to track cells in living organisms with sensitivity, accuracy and high spatial resolution would revolutionize the way we study disease. Reporter genes are valuable tools as they encode detectible products, allowing for quantitative “reporting” of cells that express them. Previously, a gene encoding Organic anion-transporting polypeptide 1a1 (Oatp1a1) was established as a magnetic resonance imaging (MRI) reporter based on its ability to take up the paramagnetic contrast agent gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA). Our objective was to assess, characterize and further develop this system for whole-body tracking of cells in vivo. Methods. Cancer cells were engineered ...

Role Of The Hyaluronan Receptor, Stabilin-2/Hare, In Health And Disease, Edward N. Harris, Erika Baker 2020 University of Nebraska-Lincoln

Role Of The Hyaluronan Receptor, Stabilin-2/Hare, In Health And Disease, Edward N. Harris, Erika Baker

Biochemistry -- Faculty Publications

Stabilin-2/HARE is the primary clearance receptor for circulating hyaluronan (HA), a polysaccharide found in the extracellular matrix (ECM) of metazoans. HA has many biological functions including joint lubrication, ocular turgor pressure, skin elasticity and hydration, cell motility, and intercellular signaling, among many others. The regulatory system for HA content in the tissues, lymphatics, and circulatory systems is due, in part, to Stabilin-2/HARE. The activity of this receptor was discovered about 40 years ago (early 1980s), cloned in the mid-1990s, and has been characterized since then. Here, we discuss the overall domain organization of this receptor and how it ...

Currently, Alzheimer’s disease (AD) has no cure. Using a rat AD model, we identified aberrantly expressed proteins during pre-pathology as potential biomarkers. The expression of certain biomarkers was reversed by diazoxide, a repurposed hypertension drug. These results suggest that drug repurposing at an early stage of AD has therapeutic potential.


Design Of A 3d Printed Bioreactor For Bone Cancer Research, Brooklyn K. VanDerWolde, Katelyn Hillson 2020 South Dakota State University

Design Of A 3d Printed Bioreactor For Bone Cancer Research, Brooklyn K. Vanderwolde, Katelyn Hillson

The Journal of Undergraduate Research

Bone cancer is an aggressive disease and has peak occurrence during physiological stimulation of growth and aging. Astronauts who undergo long-term space missions also acquire an increased risk of bone tissue degeneration and cancer. Few in-vitro models currently exist capable of reproducing the complex microenvironment of bone tissue to support multicellular activity in a three-dimensional structure. This limits the ability to understand disease progression and develop suitable treatment strategies. Therefore, developing a bone tissue model and an associated bioreactor is critical to understand the risks associated with cancer progression and improve treatment and preventions related to those risks. The goal ...


Editing Fusarium Graminearum Using Crispr/Cas9, Grace Marie Sack 2020 University of Northern Iowa

Editing Fusarium Graminearum Using Crispr/Cas9, Grace Marie Sack

Honors Program Theses

Fusarium graminearum is a pathogenic fungus that causes scab or Fusarium head blight disease in barley and wheat. Alternative approaches to protect barley from this devastating disease are badly needed. In recent years, an RNA-guided genome-editing system known as clustered regularly interspaced short palindromic repeat and CRISPR-associated protein 9 (CRISPR/Cas9), has become a popular method for genome modification (Jinek et al., 2012). We applied CRISPR/Cas9 technology in an effort to make F. graminearum less infectious. We used CRISPR/Cas9 plasmids constructed by a former UNI student (Akers, 2019) to mutate three genes in F. graminearum. One of the ...


Multiplexed Crispr Libraries For Cancer Functional Genomics, Jintan Liu 2020 The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences

Multiplexed Crispr Libraries For Cancer Functional Genomics, Jintan Liu

The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences Dissertations and Theses (Open Access)

High-throughput forward genetic screenings are invaluable tools to systematically explore genetic interactions and to link gene disruption with disease contexts. The adaptation of CRISPR/Cas9 has improved the sensitivity and specificity of functional screenings. Despite this advance, there remains a long-standing need to improve functional screenings with smaller and more versatile pooled libraries. Capitalizing on the inherent multiplexing capability of a class 2 CRISPR enzyme AsCpf1, we developed a multiplexed, high throughput screening strategy that has avoided the usual trade-off between library size and library penetration, allowing library minimization without sacrificing gene targeting efficiency. We optimized the AsCpf1 protein for ...

Direct Evidence Of Missing Mepsps Using Ca2-Sensor Imaging, Petar Gajic 2020 University at Albany, State University of New York

Direct Evidence Of Missing Mepsps Using Ca2-Sensor Imaging, Petar Gajic

Biological Sciences

Following an action potential in the presynaptic neuron there is evoked release of neurotransmitter into the synapse which activates ionotropic transmembrane receptors on the postsynaptic membrane that cause depolarizations in voltage that get recorded as excitatory postsynaptic potentials (EPSPs). In the absence of an action potential there is spontaneous release of neurotransmitter that postsynaptically gets recorded as miniature excitatory postsynaptic potentials (mEPSPs). According to the quantal hypothesis, postulated by Bernard Katz, the mEPSPs are allor- none changes in potential caused by a single quantum of neurotransmitter, which when added up create EPSPs. Following studies have found that these two modes ...
