While the cure rates for pediatric ALL have improved over the decades, infants with ALL (iALL) have not benefitted from these advances and continue to have a devastating prognosis. Unfortunately progress in treatment has also been slowed by inadequate research models. With this project, we address this unmet need by investigating a novel model to understand the cellular and molecular changes that occur during iALL onset and progression.

The Neuroprotective Role Of Lipoxin A4 In Reinstating Blood Brain Barrier Integrity In Neuroinflammatory Disease Processes, Minjal Patel, Nimish Acharya

Rowan-Virtua Research Day

Background: The blood-brain barrier (BBB), formed by the vascular endothelium, astrocytic foot processes, pericytes, is a highly selective barrier that is responsible for maintaining brain homeostasis and ultimately proper neuronal function. Disruption of the BBB, leading to increased BBB permeability, has been reported in several neurodegenerative diseases, including Alzheimer’s disease (AD) and traumatic brain injury (TBI).¹ Loss of BBB integrity leads to the proliferation of pro-inflammatory cytokines, including TNFɑ, IL-1β, and IL-6.² Moderate inflammation has a beneficial response in the system following an acute injury. However, prolonged inflammation has been known to perturb homeostasis and have …

Interactions Between Repetitive Mild Traumatic Brain Injury And Methylphenidate Administration On Catecholamine Transporter Protein Levels Within The Rodent Prefrontal Cortex, Anna Abrimian, Eleni Papadopoulos, Christopher P. Knapp, J. Loweth, Barry Waterhouse, Rachel Navarra

Rowan-Virtua Research Day

It is theorized that low concentrations of dopamine (DA) and norepinephrine (NE) within in the prefrontal cortex (PFC) following traumatic brain injury (TBI) leads to increased risky behavior. Our lab has shown that repeated mild TBI (rmTBI) sex-differentially increases risky behavior in a rodent model. Methylphenidate (MPH) is a psychostimulant drug used to treat symptoms of Attention-Deficit Hyperactivity Disorder (ADHD), also driven by a hypo-catecholaminergic PFC. MPH elevates catecholamine levels by blocking DA and NE transporters, DAT and NET. While the potential of psychostimulants to treat post-TBI symptoms have been explored, the effects of sub-chronic MPH on transporter levels following …

Relationship Between Gut Microbiota And Dementia, Saad Ahmed, Zackary Harris, Russell David Levi

Rowan-Virtua Research Day

This paper explores the complex relationship between gut microbiota, dietary habits, and dementia, focusing particularly on Alzheimer's disease (AD). Growing evidence suggests a significant link between the composition of gut bacteria, dietary choices, and susceptibility to dementia. Notably, individuals with dementia demonstrate a noticeable reduction in gut bacteria diversity, highlighting the crucial role of a balanced microbiome in maintaining cognitive health. Conversely, dietary preferences characterized by excessive consumption of processed foods and sugars are associated with an increased risk of dementia, emphasizing the critical influence of diet on shaping gut microbiota and subsequent neurocognitive outcomes. Importantly, dietary interventions featuring a …

Comparative Analyses Of Adeno-Associated Viral Vector Serotypes 1, 2 And 9 In The Sod Mouse Model Of Amyotrophic Lateral Sclerosis, Talia Hartman, Jeremy Francis, Paola Leone

Rowan-Virtua Research Day

6–7-week-old G93A SOD mice were given 1x1010 vector genomes of three different self-complimentary (sc) AAV capsid serotypes (AAV1, 2, and 9) all containing an identical CBh-driven GFP reporter expression cassette. Each serotype was delivered via either the intrathecal (IT) or intra cisterna magna (ICM) route of administration (ROA). Transduction by each serotype, via each of the two ROA was compared for the cortex and each of the lumbar, thoracic, and cervical regions of the spinal cord, with percent neuronal tropism calculated in each region. AAV2 was effective at transducing spinal cord neurons but disappointingly ineffective at transducing cortical neurons by …

Efficacy Of Mcl-1 Inhibitors In Multiple Myeloma Cells Resistant To Bortezomib, Emily Nelson, Omar S. Al-Odat, Sabrina M. Paparo, Daniel A. Guirguis, Gabriella Yao, Manoj Pandey, Subash Jonnalagadda, Tulin Budak-Alpdogan

Multiple myeloma (MM) is a type of cancer that affects plasma B cells. Patients with MM often experience frequent relapses and can develop resistance to drugs. As a medical researcher, it is important to understand the role of Mcl-1 in preventing intrinsic apoptosis and drug resistance. Mcl-1 belongs to the anti-apoptotic subgroup of Bcl-2 family proteins and plays a crucial role in these processes. Mcl-1 plays a crucial role in driving disease progression and contributing to drug resistance in MM. It has been observed that there is an increased expression of Mcl-1 in 52% of patients with MM during diagnosis, …

Intra-Accumbens Microinfusion Of The Dopamine D3 Receptor Partial Agonist (±)Vk4-40 Does Not Affect Basal Locomotion In Mice, Yeonwoo Sim, Nicole M. Hinds, Amy Hauck Newman, Daniel F. Manvich

Rowan-Virtua Research Day

The opioid epidemic remains a pressing public health crisis, prompting the search for alternative pharmacotherapies for Opioid Use Disorder (OUD). This study explores the potential of the dopamine D3 receptor (D3R) partial agonist, (±)VK4-40, as a novel treatment option. We investigated the impact of intra-nucleus accumbens (NAc) microinfusion of VK4-40 on basal locomotion in mice. Results indicate that VK4-40 did not significantly alter basal locomotion, suggesting that its therapeutic effects may not be mediated through disruptions in generalized motor function. Future research will focus on elucidating the neuropharmacological mechanisms underlying VK4-40's therapeutic actions and exploring its effects on psychostimulant-induced hyperlocomotion. …

Pediatric Neurotropic Infection Alters Synaptic Development In The Developing Brain, Anuoluwapo Grace Fadare, Yashika S. Kamte, Manish N. Chandwani, Lauren A. O'Donnell

Rowan-Virtua Research Day

Many neurotropic viruses cause more significant pathology in younger hosts as their brains are still developing. This experiment asked how central nervous system (CNS) viral-infections affect the development of synapses in the pediatric brain during infection and post-infection. Synaptogenesis is at its peak in pediatric mice (10 days old) and we hypothesized that a neurotropic infection could disrupt synaptic proteins. We used a transgenic mouse model where measles virus (MV) infects only mature neurons, leading us to question whether synapses were impacted. We examined synaptic markers in the cerebellum and hippocampus in MV-infected and uninfected mice 9 days and 90 …

Effect Of Dosage On Severity Of Dysphagia In A Toxicological Rat Model Of Parkinson's Disease, Shivam Patel, Taylor Good, Nicholas Zanghi, Francois Gould

Rowan-Virtua Research Day

Parkinson’s Disease (PD) is a prevalent and devastating neurodegenerative disorder that causes progressively worsening motor symptoms affecting locomotor and oropharyngeal function. There is limited research in animal models on swallowing dysfunction in PD. To examine how neurodegeneration in PD produces progressive impairment in the oropharyngeal and locomotor processes, rotenone, a type II mitochondrial inhibitor, was injected into Lewis rat models to reproduce a parkinsonian phenotype. We hypothesized that the animal models injected with the rotenone will exhibit both oropharyngeal dysfunction and locomotor deficiency with an increased deficit that correlates with prolonged treatment. We utilized 18 rats receiving either 2.75 mg/kg …

A Preliminary Report On The Role Of Lipoxin A4 In Reinstating The Blood-Brain Barrier Integrity In A Rodent Model Of Acute Inflammation With Impaired Cerebrovasculature, Minjal Patel, Shruti Varshney, Ananya Nethikunta, George G. Godsey, Mary C. Kosciuk, Ana Rodriguez, Bernd Spur, Kingsley Yin, Randel L. Swanson, Venkat Venkataraman, Robert G. Nagele, Nimish Acharya

Rowan-Virtua Research Day

Background: The blood-brain barrier (BBB) is responsible for maintaining brain homeostasis and ultimately proper neuronal function. Disruption of the BBB, leading to increased BBB permeability, has been reported in several neurodegenerative diseases, including Alzheimer’s disease (AD) and traumatic brain injury (TBI). Lipoxins (LXs) are a class of arachidonate-derived eicosanoids, which are a class of specialized pro-resolving lipid mediators (SPMs). SPMs are known to inhibit immune response through inhibition of cellular infiltration, downregulation of pro-inflammatory mediators and upregulation of anti-inflammatory mediators. Hence, LXs are recognized as “breaking signals” in the inflammatory process. One form of LXs, Lipoxin A4 (LXA4) …

Investigating The Therapeutic Potential Of Soursop In Treating Hematologic Malignancies, Sabrina Marie Paparo, Rebeca Mendoza, Robert Chitren, Omar Al-Odat, Emily Nelson, Subash Jonnalagadda, Roger Strair, Manoj Pandey

Rowan-Virtua Research Day

Acute Myeloid Leukemia (AML) and Multiple Myeloma (MM) are hematologic malignancies that originate in the bone marrow and account for approximately 1.3% and 2% of cancer cases, respectively. AML is characterized by an accumulation of myeloblasts, or immature myeloid cells, that have the potential to spread to the peripheral blood. There is an uncontrolled proliferation of plasma cells in the bone marrow in MM. While the current treatment options for both AML and MM show promise in achieving initial remission, it is unfortunately common for patients to experience relapse and develop drug resistance. There is a theory that relapse and …

Isolation Of Aged Mouse Primary Microglia As A Model System For Alzheimer’S Disease Research, Michael Landis

Biology Honors Papers

Microglia and their role as the immune cells of the central nervous system are an emerging area of interest within Alzheimer’s research, particularly as they have shown in a benevolent and malevolent cellular context. Models of Alzheimer’s disease are very light in studying microglia, so in this study a model of microglia isolated from aged mice is established in order to study the phagocytic activity and protein expression of microglia in response to Amyloid Beta. The cells were isolated from aged mice and cultured before being used to confirm cellular identity, as well as to measure phagocytic activity. This study …

Sarcopenia And The Importance Of Resistance Training And Protein-Rich Diets For Prevention Of Muscle Loss In Older Adults: A Literature Review And Informational Pamphlet, Madison Steele

Honors Theses

The growing prevalence of sarcopenia among older adults as well as youths has prompted further research aimed at developing effective preventative measures and treatment plans. Sarcopenia is often thought to occur solely due to aging, but several other factors contribute to progressive muscle loss. Previous research studies have found an effect of physical activity and dietary protein levels on the risk of developing sarcopenia as well as its onset age. This study aims to review existing knowledge in the field to compile an extensive list of sarcopenia causes and methods of prevention. The main causes identified in this review are …

A Meta-Analysis For Laboratory Diagnostics For Coccidioidomycosis, Mary C. Cowen

Biological Sciences Undergraduate Honors Theses

Coccidioidomycosis, commonly referred to as Valley Fever, is a fungal infection found in arid regions of the southwestern United States and Mexico. Infection occurs through inhalation of airborne spores from Coccidioides species, Coccidioides immitis and/or Coccidioides posadasii, and proceeds in both pulmonary and disseminated fashions. Approximately 60% of patients with coccidioidomycosis remain asymptomatic, while 40% will experience symptoms. Within the literature, there are no papers that summarize sensitivity and specificity values between different tests; therefore, this paper presents sensitivity and specificity results across different tests and companies (Meridian, IMMY, and MiraVista).

The Role Of B Cell Activation State And Sex In Aryl Hydrocarbon Receptor Mediated Induction Of Chemokine Receptor 9 And Alpha4beta7 Expression In Vitro, Logan Bauerle

Master's Theses

Defense of mucosal tissues from microbial infection and allergy is reliant on continual production of antibodies. The aryl hydrocarbon receptor (AhR) is known to regulate B cell development and is associated with suppression of systemic humoral immunity. Recent attention has been paid to the role of the AhR in altering expression of cell adhesion molecules (CAMs). B cells express CAMs and chemokine receptors to migrate around the body for localized secretion of antibodies. AhR agonists promote B cell migration to the small intestine through upregulation of chemokine receptor 9 (CCR9) and integrin α₄β₇. Both the AhR …

Decorin Suppresses Tumor Lymphangiogenesis: A Mechanism To Curtail Cancer Progression, Dipon K. Mondal, Christopher Xie, Gabriel J. Pascal, Simone Buraschi, Renato V. Iozzo

Kimmel Cancer Center Faculty Papers

The complex interplay between malignant cells and the cellular and molecular components of the tumor stroma is a key aspect of cancer growth and development. These tumor-host interactions are often affected by soluble bioactive molecules such as proteoglycans. Decorin, an archetypical small leucine-rich proteoglycan primarily expressed by stromal cells, affects cancer growth in its soluble form by interacting with several receptor tyrosine kinases (RTK). Overall, decorin leads to a context-dependent and protracted cessation of oncogenic RTK activity by attenuating their ability to drive a prosurvival program and to sustain a proangiogenic network. Through an unbiased transcriptomic analysis using deep RNAseq, …

Developing Zntpp-4ab As A Potential Photodynamic Therapy Agent, Kennedy Johnson

Scholars Day Conference

Photodynamic therapy is a fairly new technique used in cancer treatment involving the use of a photosensitizer and light exposure to kill malignant cells. In this research, the use of ZnTPP-4AB as a photosensitizer and red light as a source of radiant light energy was explored in terms of cytotoxicity in the A549 lung cancer cell line. ZnTPP-4AB was synthesized by replacing the carbonyl functional groups on the ZnTPPC porphyrin with 4-amino-1-butanol. Following synthesis, the new porphyrin was purified through the use of Sephadex LH-20 and G-50 in column chromatography in order to remove impurities. To confirm the identity and …

Investigating Vital Neutrophil Extracellular Trap Pathogen Response In Neutropenic Individuals, Ryan Illig

Thinking Matters Symposium

Neutrophils, also called polymorphonuclear leukocytes (PMNs), constitute the majority of innate immune cells. These cells possess a complex arsenal of functions that allow them to detect and eliminate a broad spectrum of pathogens. Neutropenia is characterized by decreased levels of neutrophils in the bloodstream, typically falling below the normal range. Moderate to severe neutropenia can increase the risk of pathogenic infections and without treatment can be life-threatening. Although the concentration of neutrophils in neutropenic individuals is decreased, upon activation, neutrophils still release neutrophil extracellular traps (NETs). NETs are pivotal in combating a spectrum of pathogens through their non-selective nature. Overreactive …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Studying the involvement of nicotinic acetylcholine receptors (nAChRs), specifically α7-nAChRs, in neuropsychiatric brain disorders such as autism spectrum disorder (ASD) has gained a growing interest. The flavonoid apigenin (APG) has been confirmed in its pharmacological action as a positive allosteric modulator of α7-nAChRs. However, there is no research describing the pharmacological potential of APG in ASD. The aim of this study was to evaluate the effects of the subchronic systemic treatment of APG (10–30 mg/kg) on ASD-like repetitive and compulsive-like behaviors and oxidative stress status in the hippocampus and cerebellum in BTBR mice, utilizing the reference drug aripiprazole (ARP, 1 …

Dysexecutive Difficulty And Subtle Everyday Functional Disabilities: The Digital Trail Making Test, David J Libon, Rod Swenson, Sean Tobyne, Ali Jannati, Daniel Schulman, Catherine C Price, Melissa Lamar, Alvaro Pascual-Leone

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship

BACKGROUND: Digital neuropsychological tests reliably capture real-time, process-based behavior that traditional paper/pencil tests cannot detect, enabling earlier detection of neurodegenerative illness. We assessed relations between informant-based subtle and mild functional decline and process-based features extracted from the digital Trail Making Test-Part B (dTMT-B).

METHODS: A total of 321 community-dwelling participants (56.0% female) were assessed with the Functional Activities Questionnaire (FAQ) and the dTMT-B. Three FAQ groups were constructed: FAQ = 0 (unimpaired); FAQ = 1-4 (subtle impairment); FAQ = 5-8 (mild impairment).

Results: Compared to the FAQ-unimpaired group, other groups required longer pauses inside target circles (p < 0.050) and produced more total pen strokes to complete the test (p < 0.016). FAQ-subtle participants required more time to complete the entire test (p …
