Increased Backbone Rigidity Of Artificial Transcription Factors, Jasmine Glover, Emma Otey, Joanna K. Kwao, Nicholas Truex

Senior Theses

Programming DNA-binding proteins is an effective strategy for developing therapeutics that regulate gene expression. These proteins can directly bind to DNA to activate or repress transcription of specific genes. Zinc finger proteins are a class of DNA-binding proteins commonly found in eukaryotic organisms. Their DNA-binding function is derived from unique amino acid sequences within each domain that recognizes specific nucleotides, allowing each finger to selectively recognize three DNA base pairs. Adjoining of multiple domains in tandem allows recognition of a specific DNA sequence. Artificial transcription factors can be made of multiple zinc finger domains arranged in tandem and engineered to …

Publications and Research

Anthocyanins are naturally occurring flavonoid pigments widely distributed in plants and are recognized for their antioxidant and anti-inflammatory activities. However, the molecular mechanisms underlying their potential immunomodulatory effects remain poorly characterized, particularly regarding their direct interactions with key signaling cytokines. In this study, a set of selected anthocyanins was investigated using a hierarchical computational workflow targeting three major pro-inflammatory cytokines: interleukin-2 (IL-2), interleukin-17 (IL-17), and tumor necrosis factor-α (TNF-α). Molecular docking analyses identified primulin and antirrhinin as the most favorable binders, forming stabilizing hydrogen bonds and hydrophobic interactions within predicted cytokine interaction interfaces. To further assess the stability of these …

The Role Of Magnesium Supplements In The Management And Prevention Of Headache Disorders, Tatum Schroeder

Libraries Undergraduate Research Award (LURA) Winners

Much of the global population suffers from headache disorders like migraine. Because there are so many triggers and unknown explanations for migraine, it can be hard to find effective treatments for it. There are some studies that point to inflammation as either a cause or result of headache disorders; therefore, it is natural that we should explore the possibility of inflammation reducing factors when considering treatment options. The factor being explored in this review is magnesium supplementation, which has been shown to reduce inflammation by decreasing the amount of calcitonin-gene-related-peptide (CGRP) in circulation. There is a clear link between migraine …

Recombinant Gelonin: Purification And Functional Validation For Electroporation-Assisted Delivery, Eleni Zivla, Giedrė Šilkūnienė, Andrei G. Pakhomov, Mantas Šilkūnas, Olga N. Pakhomova

Knowledge and Creativity Expo

Type I ribosome-inactivating proteins, such as gelonin, are enzymatically potent toxins but are effectively non-toxic under physiological conditions because they are unable to cross the plasma membrane[1]. Pulsed electric fields (PEF) overcome this delivery barrier by transiently permeabilizing the plasma membrane, allowing direct cytosolic entry. This enhances gelonin cytotoxicity by several thousand-fold, highlighting gelonin’s potential as an electrochemotherapy candidate[2]. Here, we present a recombinant gelonin (rGel) expression platform in E. coli with HPLC-based purification that enables reproducible protein production and structure-guided engineering.

The mature gelonin sequence (residues 47–297) was cloned into pET-32a(+) with an N-terminally fused Trx-6×His tag and TEV …

Egf Enhances Re-Epithelization In Our Ex-Vivo Pig Eye Model, Andrew D. Le, Lisandra Plana-Ramos, Kate Tarvestad, Brian Ceresa

The Cardinal Edge

The cornea, the foremost anterior portion of the eye, plays a critical role in vision by refracting light and serving as a protective barrier. Its three distinct layers—the outermost epithelial layer, the thick stromal layer, and the innermost endothelial layer work together to maintain corneal transparency and function. The epithelial layer is particularly susceptible to damage, which can compromise the eye’s defense against foreign particles such as bacteria and viruses, potentially leading to infection and blindness. In this study, we established an ex vivo porcine corneal model to quantitatively and qualitatively investigate corneal re-epithelialization. Using adult pig eyes sourced from …

The HPC tumors are the most lethal malignant tumors in the world. Traditional chemotherapy offers little survival benefit and is associated with notable systemic toxicity, which has made antibody–drug conjugates (ADCs) a hopeful treatment option. Strong cytotoxic drugs combine with monoclonal antibodies to attack tumor-associated antigens. This review discusses the benefits and current developments of Antibody–Drug Conjugates (ADCs) in treating HPC. It also covers their mechanisms of action, ongoing clinical trials, and the …

Breaking Into Hiv-1'S Epigenetic Vault: Cure Strategies To Eliminate The Viral Reservoir, Joanna Jones, Chelsea Gunderson, Brian Wigdahl, Michael Nonnemacher

Kimmel Cancer Center Faculty Papers

Human immunodeficiency virus type 1 (HIV-1) is a retrovirus that integrates into the host cell's DNA as a provirus. Transcription from the provirus is regulated in large part by cellular proteins and epigenetic factors. These may be repressive or permissive to productive infection. The host factors that regulate this balance are therefore attractive targets for HIV-1 therapeutics. Indeed, proviral chromatin is the focus of two of the current HIV-1 cure strategies. "Shock and Kill" uses latency reversal agents to open the provirus's chromatin, promoting high levels of gene expression that induce the killing of infected cells. "Block and Lock" uses …

No Effect In Plasma Corticosterone Levels After Observation Of Diseased Conspecifics, B. M. Hardy, M. Chang, S. Mccallum, S. Santangelo, Patricia C. Lopes

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Organisms commonly respond to stressors in their environment by increasing the secretion of corticosterone (CORT). While increased CORT is acknowledged as a response to predation risk by organisms inhabiting a landscape of fear, new research raises the potential for changes in CORT as a response to the risk of infection by organisms in their environment. An increase in CORT of a healthy, uninfected individual in response to their perception of the risk of infection in their environment could change their susceptibility to infection, highlighting a significant role for CORT to alter host–pathogen dynamics. To investigate the effects of infection risk …

Pharmacy Faculty Articles and Research

To investigate how ring size and backbone flexibility influence antimicrobial potency and cytotoxicity, we synthesized a series of macrocyclic peptides of lead peptide p1 (c[Arg-Arg-arg-arg-dip-Trp-dip]) by incorporating Gly, 2-aminoethoxyacetic acid (EAA), or 2,4-diaminobutyric acid (Dab). Two optimized peptides, 6b and 10b, retained broad-spectrum activity against drug-resistant Gram-positive (MIC, 1.5–6.2 μg/mL) and Gram-negative bacteria (MIC, 4–25 μg/mL), as well as pathogenic fungi, while exhibiting enhanced selectivity for microbial cells. Their therapeutic indices (TI ∼407 and ∼394, respectively) were ∼2-fold higher than p1, indicating improved safety. Both peptides remained effective against Gram-negative pathogens beyond the reach of daptomycin, were rapidly bactericidal, and …

Turning Zwitterions Into Toughening Agents: Salt-Activated Microdomains In Poly(Vinyl Alcohol) Double-Network Hydrogels, Louis D. Zhang, Jintao Yang, Si Yu Zheng

University Research

Zwitterionic hydrogels, although highly biocompatible, are widely regarded as mechanically fragile, with typical tensile strengths below 0.1 MPa, which restricts their use in load-bearing applications. Here, we address this limitation by integrating a polyzwitterionic network with a poly(vinyl alcohol) (PVA) network through high-speed pregelation agitation that enhances chain entanglement and induces flow orientation. By exploiting the salt-driven conformational transition of zwitterionic chains, a controlled salting-out step generates uniformly dispersed nanoscale microdomains that act as reversible energy-dissipating units. At the same time, balanced hydrogen bonding between the two networks moderates PVA crystallinity, limiting embrittlement while preserving elasticity. The resulting double-network hydrogel …

Microbiome-Responsive Hydrogels: From Biological Cues To Smart Biomaterials, Rajesh Vadlapatla, Amir Nasrolahi Shirazi, Ajoy Koomer, Judy Weng, Matthew Ernest Ghilarducci, Alai Qudus, Keykavous Parang

Pharmacy Faculty Articles and Research

Background: Stimuli-responsive hydrogels (SRHs) are smart polymeric materials that undergo reversible physicochemical changes in response to abiotic cues and externally applied fields, enabling applications in drug delivery, wound healing, and tissue engineering. However, they exhibit limited biological specificity and do not adequately reflect the dynamic, disease-relevant complexity of native tissue microenvironments. Microbe-colonized tissues display distinctive biochemical features driven, shaped by microbial metabolism, including localized pH gradients, short-chain fatty acid production, secretion of quorum-sensing molecules, biofilm formation, and expression of specialized enzymes. These endogenous, spatiotemporally regulated signals are closely linked to host physiology and pathology but remain underutilized in hydrogel …

Disruption Of Proteoglycan 4 (Prg4)-Cd44 Signaling Modulates Chronic Synovitis In Conditionally Inactivated Mice, Khaled A. Elsaid, Ling Zhang, Thomas Zhao, Ava Marks, Derek Jenkins, Gregory D. Jay

Pharmacy Faculty Articles and Research

Background

Proteoglycan-4 (PRG4) is a mucinous glycoprotein secreted by synovial fibroblasts and superficial zone chondrocytes. PRG4 inhibits synovial macrophage (SM) activation via xanthine oxidase (XO) and hypoxia inducible factor alpha (HIF-1α) suppression. We aimed to evaluate the contribution of PRG4-CD44 interaction to synovial homeostasis and investigate PRG4’s signaling dysfunction in synovial tissues from patients with osteoarthritis (OA). We hypothesized that CD44 mediates synovitis due to PRG4 loss and that PRG4 signaling dysfunction is associated with high-grade synovitis in OA.

Methods

Prg4^{FrtloxP/FrtloxP} are transgenic mice wherein tamoxifen (TAM) inactivates the Frt allele and creates a knockout state (Prg4^{FrtKO/FrtKO …}

Exploring The Theoretical Foundation With Rupture And Delayed Rupture Experiments, Shi-Qing Wang, Junpeng Wang, Asal Y. Siavoshani, Cheng Liang

University Research

We carry out uniaxial continuous and step stretching of various cross-linked polymer networks to demonstrate how characteristics of rupture during continuous stretching and delayed rupture after step stretching can be used to probe the structure of the emergent kinetic activation theory of bond dissociation (KATBD) for elastomeric failure. Based on delayed rupture experiments, we show that the network lifetime tntw, taken as the incubation time tdel-rupt for delayed rupture, depends on temperature in an Arrhenius like manner and is exponentially sensitive to the degree of network stretching (depicted by the step-stretch ratio λss). Rupture at λb during continuous stretching for …
