Determining The Genetic Control Of Neural Tube Malformation Through Genetic Interactions With Idgf3, Elli N. Fox

Honors Projects

Genetic mutations disrupting human neural tube formation can lead to birth defects such as spina bifida and anencephaly. Defects can result in lack of neural tube closure in either the caudal (spina bifida) or cranial (anencephaly) regions. Little is known about the genes that cause these malformations. Researchers have been using the model organism Drosophila melanogaster in an attempt to determine genes responsible for neural tube malformations. Recently, an ortholog of human chitin-like protein, imaginal disc growth factor 3 (Idgf3), has been identified as important in the proper formation of Drosophila egg dorsal appendages. However, the molecular mechanism responsible for …

A Follow-Up Phone Call To Post-Operative Patients Using The Five A’S, Brittney Ochs

Doctor of Nursing Practice Final Manuscripts

Abstract

Background: The 2016 National Survey on Drug Use and Health reported that 53 percent of people that misused pain relievers in the past year received them from a friend or relative. The NIDA describes that from 2002 to 2008 that drug abuse in service members went from 2% to 11%. Often patients are initially prescribed and introduced to opioid medication for acute pain. One such circumstance is in the perioperative period that could provide an opportunity to promote opioid-sparing techniques to reduce the exposure to opioids.

Purpose of Project: To assess discharge medication characteristics and reinforce discharge medication instructions …

High plasma LDL cholesterol (LDL-c) concentration is a major risk factor for atherosclerosis. Hepatic LDL receptor (LDLR) regulates LDL metabolism, and thereby plasma LDL-c concentration. Recently, we have identified the (pro)renin receptor [(P)RR] as a novel regulator of LDL metabolism, which regulates LDLR degradation and hence its protein abundance and activity. In silico analysis suggests that the (P)RR is a target of miR-148a. In this study we determined whether miR-148a could regulate LDL metabolism by regulating (P)RR expression in HepG2 and Huh7 cells. We found that miR-148a suppressed (P)RR expression by binding to the 3’-untranslated regions (3’-UTR) of the (P)RR …

Structural brain changes in aging are known to occur even in the absence of dementia, but the magnitudes and regions involved vary between studies. To further characterize these changes, we analyzed paired MRI images acquired with identical protocols and scanner over a median 5.8-year interval. The normal study group comprised 78 elders (25M 53F, baseline age range 70-78 years) who underwent an annual standardized expert assessment of cognition and health and who maintained normal cognition for the duration of the study. We found a longitudinal grey matter (GM) loss rate of 2.56 ± 0.07 ml/year (0.20 ± 0.04%/year) and a …

Innate immune activation is a major contributor to Alzheimer’s Disease (AD) pathophysiology, although the mechanisms involved are poorly understood. Chemokine C-C motif ligand (CCL) 2 is produced by neurons and glial cells and is upregulated in the AD brain. Transgene expression of CCL2 in mouse models of amyloidosis produces microglia-induced amyloid β oligomerization, a strong indication of the role of these activation pathways in the amyloidogenic processes of AD. We have previously shown that CCL2 polarizes microglia in wild type mice. However, how CCL2 signaling contributes to tau pathogenesis remains unknown. To address this question, CCL2 was delivered via recombinant …

To date current therapies of glioblastoma multiforme (GBM) are largely ineffective. The induction of apoptosis by an unresolvable unfolded protein response (UPR) represents a potential new therapeutic strategy. Here we tested 12ADT, a sarcoendoplasmic reticulum Ca2+ ATPase (SERCA) inhibitor, on a panel of unselected patient-derived neurosphere-forming cells and found that GBM cells can be distinguished into "responder" and "non-responder". By RNASeq analysis we found that the non-responder phenotype is significantly linked with the expression of UPR genes, and in particular ERN1 (IRE1) and ATF4. We also identified two additional genes selectively overexpressed among non-responders, IGFBP3 and IGFBP5. CRISPR-mediated deletion of …

Intranasal Administration Of Pcrv Conjugated To A Tobacco Mosaic Virus Delivery Platform Protects Against P. Aeruginosa In A Murine Model Of Acute Pneumonia, Eman Barahim

NYMC Student Theses and Dissertations

Pseudomonas aeruginosa is a facultative anaerobic bacterium that is the most common type of Gram-negative bacteria causing nosocomial pneumonia in the United States. P. aeruginosa is an opportunistic pathogen ubiquitously found in the atmosphere that can colonize both plants and animals. It is known to cause a wide range of severe, persistent, and fatal infections ranging from acute and chronic pneumonia, skin and soft tissue infections to urinary tract infections, especially in immune-compromised individuals. Patients with cystic fibrosis are at high risk because of deficiencies in mucosal immunity and phagocytosis. Ultimately, Pseudomonas infections can be lethal. There is a very …

Overexpression Of Mig-6 In The Cartilage Induces An Osteoarthritis-Like Phenotype In Mice, Melina Bellini, Michael A. Pest, Manuela Miranda-Rodrigues, Ling Qin, Jae Wook Jeong, Frank Beier

Physiology and Pharmacology Publications

© 2020 The Author(s). Background: Osteoarthritis (OA) is the most common form of arthritis and characterized by degeneration of the articular cartilage. Mitogen-inducible gene 6 (Mig-6) has been identified as a negative regulator of the epidermal growth factor receptor (EGFR). Cartilage-specific Mig-6 knockout (KO) mice display increased EGFR signaling, an anabolic buildup of the articular cartilage, and formation of chondro-osseous nodules. Since our understanding of the EGFR/Mig-6 network in the cartilage remains incomplete, we characterized mice with cartilage-specific overexpression of Mig-6 in this study. Methods: Utilizing knee joints from cartilage-specific Mig-6-overexpressing (Mig-6 over/over ) mice (at multiple time points), we …

Vascular Risk Reduction In Obesity Through Reduced Granulocyte Burden And Improved Angiogenic Monocyte Content Following Bariatric Surgery., David A Hess, Justin Z Trac, Stephen A Glazer, Daniella C Terenzi, Adrian Quan, Hwee Teoh, Mohammed Al-Omran, Deepak L Bhatt, C David Mazer, Ori D Rotstein, Subodh Verma

Bariatric surgery, in addition to the benefit of sustained weight loss, can also reduce cardiometabolic risk and mortality. Lifelong vessel maintenance is integral to the prevention of cardiovascular disease. Using aldehyde dehydrogenase activity, an intracellular detoxifying enzyme present at high levels within pro-vascular progenitor cells, we observed an association between chronic obesity and "regenerative cell exhaustion" (RCE), a pathology whereby chronic assault on circulating regenerative cell types can result in adverse inflammation and diminished vessel repair. We also describe that, at 3 months following bariatric surgery, systemic inflammatory burden was reduced and pro-angiogenic macrophage precursor content was improved in subjects …

The Apicomplexan-Specific Fikk Kinase Is Crucial For Cyst Formation In Toxoplasma Gondii, Corey Gaylets

NYMC Student Theses and Dissertations

Toxoplasma gondii is an obligate intracellular pathogen. It is considered the second deadliest foodborne pathogen in the world with up to 1/3 of the human population estimated to be currently infected. The majority of immune competent people may exhibit mild symptoms following T gondii infection. The acute stage of infection is often well controlled by cellular immunity in healthy individuals. However sterilizing immunity does not occur as the tachyzoite stage of the parasite responsible for acute infection differentiates to a slow growing bradyzoite stage contained in tissues cysts that can persist for the life of the host. However, if the …

Endothelial Progenitor Cell-Breast Cancer Interaction, Ghada Ben Rahoma

NYMC Student Theses and Dissertations

Breast cancer remains the second leading cause of cancer death among women in the U.S. Although organ-confined disease is curable, metastatic disease remains incurable and an unmet clinical need. Hence, the development of new therapeutic targets and further understanding of the genesis of malignant progression is needed and to this end analysis of the tumor microenvironment is imperative for novel therapeutic targets in breast cancer. We and others have demonstrated that bone marrow derived endothelial progenitor cells (EPCs) incorporate in the neovasculature around implanted tumors supporting their growth and metastasis. The incorporation of EPCs from the marrow to the tumor …

Cell Surface Regulatory Immune Targets In Anaplastic Thyroid Cancer, Sanjukta Chakraborty

NYMC Student Theses and Dissertations

Thyroid cancer incidence is increasing at an alarming rate almost trebling every decade. 52,070 new cases of thyroid cancer (14,260 in men and 37,810 in women) were diagnosed in 2019 with an estimated death toll of 2170. Although most thyroid tumors are treatable and has good prognosis, anaplastic thyroid cancer (ATC) is extremely aggressive with a grim poor prognosis of 6-9 months post diagnosis. ATC is completely refractory to mainstream therapies. In our study, immunohistochemical analyses of ATC tissues confirmed a T cell inflamed “hot” tumor immune microenvironment (TIME) as evidenced by presence of CD3+ and CD8+ T cells. This …

Fall Prevention Assessment in the Intermediate Care Patient Population

Falls cause greater than 600,000 deaths per year and are the most common injury in people over 65 years of age. Fall prevention in the acute care setting has been identified as key goal in the most recent JCAHO review process. Falls on an intermediary care unit lead to an increased rate of morbidity, delayed discharge, and excess cost expenditure.

Even with appropriate evidence-based tools in place, Hospital A’s intermediate care unit, recorded an increased rate of falls; the highest rate in its health care system. An investigation identified factors contributing …

Chronic pancreatitis (CP) is a major risk factor of pancreatic ductal adenocarcinoma (PDAC). How CP promotes pancreatic oncogenesis remains unclear. A characteristic feature of PDAC is its prominent desmoplasia in the tumor microenvironment, composed of activated fibroblasts and macrophages. Macrophages can be characterized as M1 or M2, with tumor-inhibiting or -promoting functions, respectively. We reported that Gremlin 1 (GREM1), a key pro-fibrogenic factor, is upregulated in the stroma of CP. The current study aimed to investigate the expression of GREM1 and correlation between GREM1 and macrophages within the pancreas during chronic inflammation and the development of PDAC. By mRNA in …

The Impact Of Genetic Counseling On Direct-To-Consumer And Patient-Initiated Testing, Jennifer Hull

KGI Theses and Dissertations

Direct-to-consumer (DTC) testing provides consumers access to genetic testing without involvement or advice from a genetics specialist. While the expansion of DTC testing has increased consumer access to genetic interpretations, these reports can often provide a false sense of security and rarely cover enough genetic information to make significant interpretations about disease risk. Patient-initiated testing involves consumers seeking out and ordering more comprehensive genetic testing on a cash pay basis. A patient’s self-reported medical and family history is reviewed by a clinician before the test is ordered. These tests are often similar to clinically ordered genetic tests, including large panels …

The Enzymatic Function Of The Tir Domain: From Axon Degeneration To Innate Immunity, Kow Essuman

Arts & Sciences Electronic Theses and Dissertations

The Toll/Interleukin-1 Receptor (TIR) domain is an evolutionarily ancient protein domain conserved from bacteria to eukaryotes, and is an essential signaling component of innate immunity pathways. In animal innate immunity, TIR domains have primarily been described for their scaffolding function in assembling protein complexes in host defense. In plant immunity, TIR domains are key components of the intracellular Nucleotide Binding Leucine rich repeat (NLR) immune receptors that confer resistance to pathogens. These NLR receptors trigger cell death and an immune response upon activation, but their mechanism has remained elusive. In bacteria, TIR domain proteins have been suggested to function as …
