Copy Number Alterations Of Aggressive Pituitary Neuroendocrine Tumors, Grace Zhang

Scripps Senior Theses

Pituitary neuroendocrine tumors (PitNETs) are tumors of the pituitary gland. Although most are benign, they can cause severe morbidity if compression of surrounding tissue and/or endocrinopathies occur.

Aggressive PitNETs are notably detrimental and difficult to predict, and their effects are further exacerbated by challenges in treatment. Although histological studies can detect certain markers of tumor aggressiveness, they are insufficient at wholly predicting PitNET aggressiveness, making the clinical behavior of PitNETs challenging to determine. Since treatment of aggressive tumors also remains suboptimal, this further results in negative impacts on health and quality of life.

Genetic markers, such as copy number variations …

Acute lung injury (ALI) followed with severe inflammation and oxidative stress. Anti-inflammatory and antioxidant are the properties of aquaporin 1 (AQP1) and aquaporin 5 (AQP5). The goal of this study was to see if soy isoflavone can diminish lipopolysaccharide (LPS)-induced ALI and the underling mechanism. LPS-induced ALI was given to Sprague-Dawley rats 14 days following oophorectomy. One hour before the LPS challenge, estradiol (1 mg/kg) was administered subcutaneously as positive control and soy isoflavone was intragastric administration for 14 days prior to LPS challenge with different doses. Six hours after LPS challenge, the pulmonary edema, pathophysiology, inflammation, and the oxidative …

Visualization And Characterization Of The Immunological Synapse Between Chlorotoxin Chimeric Antigen (Cltx-Car) Redirected T Cells And Targeted Glioblastoma Tumors, Arianna Livi

CMC Senior Theses

Chimeric Antigen Receptor T (CAR-T) cells have demonstrated anti-tumor activity against aggressive and invasive cancers such as glioblastoma (GBM); however, clinical response rates remain low in clinical trial studies. Tumor heterogeneity and tumor microenvironment conditions pose significant challenges for treatment of GBM, thus continuous optimization of CAR-T cell therapies and identification of novel, widely expressed, and highly specific GBM antigens are vital to better patient outcomes. A newly developed CAR-T cell construct incorporating chlorotoxin (CLTX) as the targeting domain exhibited broad GBM-targeting capabilities and elicited potent cytotoxic effects during preclinical studies and is currently being tested in a phase I …

Syntaxin 3b Is A T-Snare Specific For Ribbon Synapses Of The Retina, Mariajose Perez-Hurtado, Calvin Dao, Amanda E Saenz, Ruth Heidelberger

Faculty, Staff and Student Publications

Biallelic loss-of-function mutations in the syntaxin 3 gene have been linked to a severe retinal dystrophy in humans that presents in early childhood. In mouse models, biallelic inactivation of the syntaxin 3 gene in photoreceptors rapidly leads to their death. What is not known is whether a monoallelic syntaxin 3 loss-of-function mutation might cause photoreceptor loss with advancing age. To address this question, we compared the outer nuclear layer of older adult mice (≈ 20 months of age) that were heterozygous for syntaxin 3 with those of similarly-aged control mice. We found that the photoreceptor layer maintains its thickness in …

The Role Of The Nlrp3 Inflammasome In Alzheimer's Disease, Ethan S. Terman

Undergraduate Research Posters

This study examines the consequences of Alzheimer’s in rat and mice test subjects. The goal is to identify the effects of certain NLRP3 inhibiting drugs and to see if there are any noticeable effects in regards to impeding the pathological development of Alzheimer’s disease. The results are visualized by implementing the immunohistochemical process to identify neurodegeneration in the brain and to assess the expression levels of amyloid beta as an indicator of Alzheimer’s pathology. Other tests are also conducted on these transgenic mice to gauge cognitive functioning levels during the onset of their disease, those being behavior tests, but not …

Nursing Considerations For Post-Traumatic Amnesia After A Traumatic Brain Injury, Hannah Grant

Senior Honors Theses

A period known as post-traumatic amnesia (PTA) often follows a traumatic brain injury (TBI). PTA is characterized by anterograde and retrograde amnesia, confusion, disorientation, and agitation. The duration and severity of PTA is a key indicator of the long-term prognosis after a TBI, so proper assessment and nursing care of a PTA patient is crucial. TBIs range from mild to severe, but primarily affect the fronto-temporal lobes. In PTA, both neural lesions and white matter damage within the parahippocampal region can cause PTA. A nurse must perform a thorough assessment of a TBI patient, but, since PTA is a key …

Combined Regulatory T-Lymphocyte And Il-2 Treatment Is Safe, Tolerable, And Biologically Active For 1 Year In Persons With Amyotrophic Lateral Sclerosis, Jason R Thonhoff, James D Berry, Eric A Macklin, David R Beers, Patricia A Mendoza, Weihua Zhao, Aaron D Thome, Fabio Triolo, James J Moon, Sabrina Paganoni, Merit Cudkowicz, Stanley H Appel

BACKGROUND AND OBJECTIVES: In a phase 1 amyotrophic lateral sclerosis (ALS) study, autologous infusions of expanded regulatory T-lymphocytes (Tregs) combined with subcutaneous interleukin (IL)-2 were safe and well tolerated. Treg suppressive function increased and disease progression stabilized during the study. The present study was conducted to confirm the reliability of these results.

METHODS: Participants with ALS underwent leukapheresis, and their Tregs were isolated and expanded in a current Good Manufacturing Practice facility. Seven participants were randomly assigned in a 1:1 ratio to receive Treg infusions (1 × 10

RESULTS: The Treg/IL-2 treatments were safe and well tolerated, and Treg suppressive …

Characterization Of A Bioactive Peptide T14 In The Human And Rodent Substantia Nigra: Implications For Neurodegenerative Disease, Susan Adele Greenfield, Giovanni Ferrati, Clive W Coen, Auguste Vadisiute, Zoltan Molnár, Sara Garcia-Rates, Sally Frautschy, Gregory M Cole

Faculty, Staff and Student Publications

The substantia nigra is generally considered to show significant cell loss not only in Parkinson's but also in Alzheimer's disease, conditions that share several neuropathological traits. An interesting feature of this nucleus is that the pars compacta dopaminergic neurons contain acetylcholinesterase (AChE). Independent of its enzymatic role, this protein is released from pars reticulata dendrites, with effects that have been observed in vitro, ex vivo and in vivo. The part of the molecule responsible for these actions has been identified as a 14-mer peptide, T14, cleaved from the AChE C-terminus and acting at an allosteric site on alpha-7 nicotinic receptors, …

Brain function is mediated by the physiological coordination of a vast, intricately connected network of molecular and cellular components. The physiological properties of neural network components can be quantified with high throughput. The ability to assess many animals per study has been critical in relating physiological properties to behavior. By contrast, the synaptic structure of neural circuits is presently quantifiable only with low throughput. This low throughput hampers efforts to understand how variations in network structure relate to variations in behavior. For neuroanatomical reconstruction, there is a methodological gulf between electron microscopic (EM) methods, which yield dense connectomes at considerable …

Comparison Of Brain Nicotine Uptake From Electronic Cigarettes And Combustible Cigarettes, Yantao Zuo, Alexey G Mukhin, Hannah Berg, Janiece D Morgan, Akiva Mintz, Jed E Rose, Kiran Kumar Solingapuram Sai

Faculty, Staff and Student Publications

Brain accumulation rate and magnitude are critical for the acute reinforcing effects of nicotine. Despite electronic cigarettes’ (E-cigs) appeal as substitutes for traditional combustible cigarettes (C-cigs), brain nicotine accumulation (BNA) from E-cigs has not been compared with that from C-cigs using a within-subjects design. BNA was directly assessed with 16 adult dual users (10 females) of E-cigs (e-liquid pH 9.4) and C-cigs, using 11C-nicotine and positron emission tomography (PET). Participants went through two 15-min head scanning sessions during which they inhaled a single puff of E-cig vapor or C-cig smoke containing 11C-nicotine in a randomized order. A full-body scan was …

Hepatocellular carcinoma (HCC) is a leading cause of cancer deaths, and the most common primary liver malignancy to present in the clinic. With the exception of liver transplant, treatment options for advanced HCC are limited, but improved tumor stratification could open the door to new treatment options. Previously, we demonstrated that the circadian regulator Aryl Hydrocarbon-Like Receptor Like 1 (ARNTL, or Bmal1) and the liver-enriched nuclear factor 4 alpha (HNF4α) are robustly co-expressed in healthy liver but incompatible in the context of HCC. Faulty circadian expression of HNF4α- either by isoform switching, or loss of expression- results in an increased …

Macrophage Migration Inhibitory Factor (Mif) Makes Complex Contributions To Pain-Related Hyperactivity Of Nociceptors After Spinal Cord Injury, Alexis Bavencoffe, Emily A Spence, Michael Y Zhu, Anibal Garza-Carbajal, Kerry E Chu, Ona E Bloom, Carmen W Dessauer, Edgar T Walters

Faculty, Staff and Student Publications

Neuropathic pain is a major, inadequately treated challenge for people with spinal cord injury (SCI). While SCI pain mechanisms are often assumed to be in the CNS, rodent studies have revealed mechanistic contributions from primary nociceptors. These neurons become chronically hyperexcitable after SCI, generating ongoing electrical activity that promotes ongoing pain. A major question is whether extrinsic chemical signals help to drive ongoing electrical activity after SCI. People living with SCI exhibit acute and chronic elevation of circulating levels of macrophage migration inhibitory factor (MIF), a cytokine implicated in preclinical pain models. Probable nociceptors isolated from male rats and exposed …

Connectomic Analysis Of The Drosophila Lateral Neuron Clock Cells Reveals The Synaptic Basis Of Functional Pacemaker Classes, Orie T. Shafer, Gabrielle J. Gutierrez, Kimberly Li, Amber Mildenhall, Daphna Spira, Jonathan Marty, Aurel A. Lazar, Maria De La Paz Fernandez

Advanced Science Research Center

The circadian clock orchestrates daily changes in physiology and behavior to ensure internal temporal order and optimal timing across the day. In animals, a central brain clock coordinates circadian rhythms throughout the body and is characterized by a remarkable robustness that depends on synaptic connections between constituent neurons. The clock neuron network of Drosophila, which shares network motifs with clock networks in the mammalian brain yet is built of many fewer neurons, offers a powerful model for understanding the network properties of circadian timekeeping. Here, we report an assessment of synaptic connectivity within a clock network, focusing on the …

Co-Transmitting Neurons In The Lateral Septal Nucleus Exhibit Features Of Neurotransmitter Switching, Patrick J Hunt, Mikhail Kochukov, Brandon T Pekarek, Benjamin D W Belfort, Juan M Romero, Jessica L Swanson, Benjamin R Arenkiel

Faculty, Staff and Students Publications

The lateral septal nucleus (LSN) is a highly interconnected region of the central brain whose activity regulates widespread circuitry. As such, the mechanisms that govern neuronal activity within the LSN have far-reaching implications on numerous brain-wide nuclei, circuits, and behaviors. We found that GABAergic neurons within the LSN express markers that mediate the release of acetylcholine (ACh). Moreover, we show that these vGATLSN neurons release both GABA and ACh onto local glutamatergic LSN neurons. Using both short-term and long-term neuronal labeling techniques we observed expression of the cholinergic neuron marker Choline Acetyltransferase (ChAT) in vGATLSN neurons. These findings provide evidence …

A Preliminary Report: The Hippocampus And Surrounding Temporal Cortex Of Patients With Schizophrenia Have Impaired Blood-Brain Barrier, Eric L. Goldwaser, Randel L. Swanson, Edgardo J. Arroyo, Venkat Venkataraman, Mary C. Kosciuk, Robert G. Nagele, L. Elliot Hong, Nimish K. Acharya

Rowan-Virtua Research Day

Schizophrenia (SZ) is one of the most severe forms of mental illness, yet mechanisms remain unclear. A widely established brain finding in SZ is hippocampal atrophy, and a coherent explanation similarly is lacking. Epidemiological evidence suggests increased cerebrovascular and cardiovascular complications in SZ independent of lifestyle and medication, pointing to disease-specific pathology. Endothelial cell contributions to blood-brain barrier (BBB) compromise may influence neurovascular unit and peripheral vascular function, and we hypothesize that downstream functional and structural abnormalities may be explained by impaired BBB.

Plasmalogen Deficiency: A Risk Factor For Dementias And Potential Treatment Target, Mitchel A. Kling, Mallika Mendu, Rima F. Kaddurah-Daouk, Sheldon Jordan, Dayan B. Goodenowe

Rowan-Virtua Research Day

Altered lipid metabolism is implicated in the risk of sporadic Alzheimer’s disease (AD) and related dementias (ADRD); however, the precise mechanisms accounting for findings from observational studies remains to be fully elucidated.

Plasmalogens are a subclass of integral membrane phospholipids with unique properties that appear to play important roles relevant to the pathophysiology of AD and ADRD, including vesicle fusion necessary for synaptic neurotransmitter release, modulation of membrane fluidity and microdomain dynamics, membrane antioxidant functions, and neuroprotection. Like the more familiar phosphatides, plasmalogens are synthesized on a 3-carbon glycerol backbone; however, they differ from phosphatides by the presence of a …

The Impact Of Volume Of Tissue Activation On Cortical-Striatal Networks And Verbal Fluency Declines In Post-Deep Brain Stimulation Parkinson's Disease Patients., Alexander Luke Alley

Electronic Theses and Dissertations

This study investigated the cortical-striatal networks of verbal fluency declines in 6-month, post-operative, deep brain stimulation Parkinson’s Disease patients. Nine Parkinson’s disease participants with implanted STN or GPi DBS systems were recruited for this study. Verbal fluency data was obtained from each patient preoperatively and 6- months post implantation. The stimulation-based volume of tissue activated area (VTA) of each target site (STN or GPi) was analyzed using Lead-DBS and Lead-Group. The white matter tracks intersecting each patient’s VTA, terminating in the pre-SMA, SMA, caudate nucleus, and anterior cingulate were investigated and correlated with verbal fluency declines. We found statistically significant …

Hdac6 Inhibition Reverses Long-Term Doxorubicin-Induced Cognitive Dysfunction By Restoring Microglia Homeostasis, Blake Mcalpin

Dissertations and Theses (Open Access)

One in 8 women in the US will be diagnosed with breast cancer. Currently, doxorubicin is one of the most effective chemotherapies for breast cancer. Unfortunately, up to 60% of survivors report long-term chemotherapy-induced cognitive dysfunction (CICD) characterized by deficits in working memory, processing speed, and executive functioning. Currently, no interventions for CICD have been approved by the US Food and Drug Administration. I show here that a 14-day treatment with a blood-brain barrier permeable histone deacetylase 6 (HDAC6) inhibitor successfully reverses long-term CICD following a therapeutic doxorubicin dosing schedule in female mice, as assessed by the puzzle box test …

The Effects Of Paclitaxel On Cellular Migration And The Cytoskeleton, Ashley Salguero-Gonzalez

Thinking Matters Symposium

In a clinical setting, some patients are exposed to an anti-cancer chemotherapy agent, paclitaxel. Cancerous cells undergo rapid, continuous cell division without control. Chemotherapy treatments try to slow and stop the uncontrollable cell division cycles and eliminate cancerous cells in the process. Paclitaxel serves as a treatment for some types of cancers, including lung, melanoma, bladder, and esophageal. Because it targets the cytoskeleton, paclitaxel can also influence cell migration. This project utilizes a cellular migration assay and an immunohistochemistry assay to analyze the effects of paclitaxel on the movement of cells and on the cytoskeleton of neuroglia rat cells with …

Actl6a Coordinates Axonal Caliber Recognition And Myelination In The Peripheral Nerve, Hye-Jin Park, Eric Tsai, Dennis Huang, Michael Weaver, Luciana Frick, Ace Alcantara, John J. Moran, Julia Patzig, Carmen V. Melendez-Vasquez, Gerald R. Crabtree, M.L. Feltri, John Svaren, Patricia Casaccia

Advanced Science Research Center

Cells elaborate transcriptional programs in response to external signals. In the peripheral nerves, Schwann cells (SC) sort axons of given caliber and start the process of wrapping their membrane around them. We identify Actin-like protein 6a (ACTL6a), part of SWI/SNF chromatin remodeling complex, as critical for the integration of axonal caliber recognition with the transcriptional program of myelination. Nuclear levels of ACTL6A in SC are increased by contact with large caliber axons or nanofibers, and result in the eviction of repressive histone marks to facilitate myelination. Without Actl6a the SC are unable to coordinate caliber recognition and myelin production. Peripheral …

Neural stem cells, the source of newborn neurons in the adult hippocampus, are intimately involved in learning and memory, mood, and stress response. Despite considerable progress in understanding the biology of neural stem cells and neurogenesis, regulating the neural stem cell population precisely has remained elusive because we have lacked the specific targets to stimulate their proliferation and neurogenesis. The orphan nuclear receptor TLX/NR2E1 governs neural stem and progenitor cell self-renewal and proliferation, but the precise mechanism by which it accomplishes this is not well understood because its endogenous ligand is not known. Here, we identify oleic acid (18:1ω9 monounsaturated …

Stereotactic Radiosurgery For Pituitary Adenomas: A Review Of Literature, Kaynat Siddiqui, Saqib Kamran Bakhshi, Muhammad Shahzad Shamim

Section of Neurosurgery

Stereotactic radiosurgery (SRS) is a choice of treatment for pituitary adenomas (PA), particularly for residual or recurrent disease, apart from surgery. It has a progression free survival and endocrine remission rate comparable to surgery, with fewer side effects, making it an ideal tool for dealing with PA. In this review, we have discussed the role of SRS for primary as well as post-operative residual/ recurrent PA, and have assessed its safety and outcomes.

Stimulating The Facial Nerve To Treat Ischemic Stroke: A Systematic Review, Turner S. Baker, Justin Robeny, Danna Cruz, Alexis Bruhat, Alfred-Marc Iloreta, Anthony Costa, Thomas James Oxley

Publications and Research

Acute ischemic stroke (AIS) is a common devastating disease that has increased yearly in absolute number of cases since 1990. While mechanical thrombectomy and tissue plasminogen activator (tPA) have proven to be effective treatments, their window-of-efficacy time is very short, leaving many patients with no viable treatment option. Over recent years there has been a growing interest in stimulating the facial nerves or ganglions to treat AIS. Pre-clinical studies have consistently demonstrated an increase in collateral blood flow (CBF) following ganglion stimulation, with positive indications in infarct size and neurological scores. Extensive human trials have focused on trans-oral electrical stimulation …

Background: Trigeminal Neuralgia (TN) is a chronic neurological disease that is strongly associated with neurovascular compression (NVC) of the trigeminal nerve near its root entry zone. The trigeminal nerve at the site of NVC has been extensively studied but limbic structures that are potentially involved in TN have not been adequately characterized. Specifically, the hippocampus is a stress-sensitive region which may be structurally impacted by chronic TN pain. As the center of the emotion-related network, the amygdala is closely related to stress regulation and may be associated with TN pain as well. The thalamus, which is involved in the trigeminal …
