Department of Surgery Faculty Papers

Recent advances in cancer treatment like personalized chemotherapy and immunotherapy are aimed at tumors that meet certain specifications. In this review, we describe a new approach to general cancer treatment, termed peptide-induced poptosis, in which specific peptides, e.g., PNC-27 and its shorter analogue, PNC-28, that contain the segment of the p53 transactivating 12-26 domain that bind to HDM-2 in its 1-109 domain, bind to HDM-2 in the membranes of cancer cells, resulting in transmembrane pore formation and the rapid extrusion of cancer cell contents, i.e., tumor cell necrosis. These peptides cause tumor cell necrosis of a wide variety of solid …

Repurposing Clinically Relevant Metabolic Inhibitor Drugs, Difluoromethylornithine (Dfmo) And Orlistat, For Gammaherpesvirus Replication, Lay Paw

Honors Projects

Viruses, including herpesviruses, contribute up to 15% of all human cancers. Murine gammaherpesvirus-68 (MHV-68), a pathogen commonly found in mice, is studied due to its shared homology with several human herpesviruses. Studies done in the Delgado lab via metabolomics analysis show MHV-68 infected cells increase host cell metabolism. Clinically relevant metabolic inhibitor drugs, ɑ-Difluoromethylornithine (DFMO) and Orlistat, respectively block polyamine and lipid production demonstrated a reduction in MHV-68 viral production. Repurposing clinically relevant drugs through the exploration of a different target shows great promise in reducing oncogenic viral titer.

Fluorescence-Based Techniques For The Identification Of Small Biomolecules, Charnette Frederic

Seton Hall University Dissertations and Theses (ETDs)

Understanding fluorescence-based methods for detecting small biomolecules is a crucial area of focus in research investigations. Our studies focused on the challenge in two parts: Non-intrinsic fluorescence and intrinsic fluorescence. For studies on Non-intrinsic fluorescence, Rifampicin (Rif), an antibiotic harnessed for treating diverse bacterial infections, including tuberculosis (TB), serves as a focal point. Leveraging the Systematic Evolution of Ligands by Exponential Enrichment (SELEX) process, aptamers emerged from the nonspecific 40-mer Deoxyribonucleic Acid (DNA) library to interact with its target, Rif. During each SELEX cycle, the recovered nucleotides underwent amplification via Polymerase Chain Reaction (PCR) until the most selective aptamers were …

Kimmel Cancer Center Faculty Papers

Breast cancer brain metastasis (BCBM) typically results in an end-stage diagnosis and is hindered by a lack of brain-penetrant drugs. Tumors in the brain rely on the conversion of acetate to acetyl-CoA by the enzyme acetyl-CoA synthetase 2 (ACSS2), a key regulator of fatty acid synthesis and protein acetylation. Here, we used a computational pipeline to identify novel brain-penetrant ACSS2 inhibitors combining pharmacophore-based shape screen methodology with absorption, distribution, metabolism, and excretion (ADME) property predictions. We identified compounds AD-5584 and AD-8007 that were validated for specific binding affinity to ACSS2. Treatment of BCBM cells with AD-5584 and AD-8007 leads to …

Antiseizure Properties Of Fenamate Nsaids Determined In Mature Human Stem-Cell Derived Neuroglial Circuits., Hamed Salmanzadeh, Robert F. Halliwell

School of Pharmacy Faculty Articles

Repeated and uncontrolled seizures in epilepsy result in brain cell loss and neural inflammation. Current anticonvulsants primarily target ion channels and receptors implicated in seizure activity. Identification of neurotherapeutics that can inhibit epileptiform activity and reduce inflammation in the brain may offer significant benefits in the long-term management of epilepsy. Fenamates are unique because they are both non-steroidal anti-inflammatory drugs (NSAIDs) and highly subunit selective modulators of GABA_A receptors. In the current study we have investigated the hypothesis that fenamates have antiseizure properties using mature human stem cell-derived neuro-glia cell cultures, maintained in long-term culture, and previously shown to …

Psilocybin Utilization In Alcohol Use Disorder, Hannah Hall, Sarah Turske, Hannah Blake, Abigail Carter, Connor Dains, Haylee Whyde, Brianna Lu, Joshua Honaker, Lindsey Peters

Pharmacy and Wellness Review

Alcohol use disorder (AUD) is a medical condition that arises from the inability to control alcohol consumption regardless of negative consequences. Over 10% of the US population met the diagnostic criteria for having AUD in 2022.1 Each individual presents with symptoms of AUD differently and may therefore need more personalized treatment. Research has shown that using a combination of currently available pharmacological and non-pharmacological treatment options provides the best results for patients with AUD. However, there still remains a pressing need for the development of newer treatment options. Psilocybin, a naturally occurring psychedelic compound, is currently under investigation due to …

Delivering Crispr To The Hiv-1 Reservoirs, Theodore Gurrola, Samuel Effah, Ilker Sariyer, Will Dampier, Michael Nonnemacher, Brian Wigdahl

Kimmel Cancer Center Faculty Papers

Human immunodeficiency virus type 1 (HIV-1) infection is well known as one of the most complex and difficult viral infections to cure. The difficulty in developing curative strategies arises in large part from the development of latent viral reservoirs (LVRs) within anatomical and cellular compartments of a host. The clustered regularly interspaced short palindromic repeats/ CRISPR-associated protein 9 (CRISPR/Cas9) system shows remarkable potential for the inactivation and/or elimination of integrated proviral DNA within host cells, however, delivery of the CRISPR/Cas9 system to infected cells is still a challenge. In this review, the main factors impacting delivery, the challenges for delivery …

The number of teens in Arkansas who are vaping continues to increase despite state and national laws and regulations. The availability of vaping devices to teens continues to occur; but limited research is available that explores if the availability is accessible through peers, families, or community members, or is self-sought. It is crucial to gain a better understanding of why vaping continues to increase among high school students in Arkansas. The purpose of this study is to understand the relationship between how the availability of vaping devices and student use are related. The analysis of exposure and student use varies …

Benzo[A]Pyrene-Induced Multigenerational Gene Expression And Dna Methylation Changes Are Influenced By Paternal Epigenome, Caroline Sturgis

Honors Theses

The objectives of this study were to determine the sex-dependent contributions to developmental and behavioral effects of preconceptional exposure to benzo[a]pyrene (BaP). BaP is implicated in numerous adverse outcomes in offspring of exposed parents, but the molecular mechanisms for the developmental and multigenerational effects associated with BaP exposures have yet to be fully elucidated. To assess the role of the aryl hydrocarbon receptor (Ahr), a waterborne exposure of the offspring of ahr heterozygous (ahr^+/-) parents was conducted. At 120 hpf, BaP treated fish moved significantly less in the dark phase regardless of genotype. At 3 wpf, there …

Zinc-Containing Over-The-Counter Product Causing Sideroblastic Anemia And Neutropenia, Marshall Patrick Stagg, Jennifer Miatech, Baseera Majid, Ravali Polala

School of Medicine Faculty Publications

Sideroblastic anemia is characterized by anemia, granulocytopenia, and bone marrow findings of vacuolated precursors and ringed sideroblasts. Zinc-induced copper deficiency can present as sideroblastic anemia and neutropenia. We report the case of a previously healthy 74-year-old female who presented with newly discovered sideroblastic anemia as a result of an over-the-counter oral vitamin and mineral supplement. Serum analysis revealed increased zinc levels, decreased copper levels, and a decrease in ceruloplasmin. Bone marrow evaluation revealed ringed sideroblasts and cytoplasmic vacuolization in myeloid precursors. She demonstrated improvement in her hematologic profile with discontinuation of the over-the-counter product and administration of oral copper supplementation. …

Investigation And Synthesis Of 2-Deoxy-Pyr(Mp), Juanita Monteiro-Pai

Poster Presentations

Cellular energy metabolism is complex, and NAD, or nicotinamide adenine dinucleotide, plays a huge role as an organic redox cofactor, driving metabolic reactions. The abundance of pathways dependent on NAD has led to an increase in the studies of NAD and its precursors. As a result, NR, or nicotinamide riboside, is now a popular nutraceutical taken to increase levels of NAD in the body. NR is a precursor to NAD inside cells. Metabolites with the same molecular formula as NR are found in urine and blood. Yet, NR is usually associated with these species in extracellular regions although NR is …
