Novel Mechanistic Divergence Of The Hsp70–Hsp110 Chaperone System In Fungi And Humans, Justin M. Kidd, Ayil Perrott, Cancan Sun, Anusri Arun Prasath, Spoorti Kalashetti, Sky Evans, Vadim Barnakov

Physiology and Biophysics Publications and Presentations

Heat shock proteins (HSPs) are conserved, ubiquitous molecular chaperones that play various roles in preserving proteostasis, particularly in response to cellular stressors (e.g., heat, oxidation). In addition, their dysregulation is linked to various diseases, including neurodegeneration, cancer, and fungal infections. HSPs are generally grouped by molecular weight into families with related functions. Members of the 70-kDa family (Hsp70s) are central, energy-driven chaperones that bind and release clients in a cyclical manner dependent on ATP hydrolysis, facilitated by multiple co-chaperones such as nucleotide exchange factors (NEFs). In addition to solubilizing protein aggregates, members of the 110-kDa family (Hsp110s) constitute the primary …

Championing Weight-Neutral Healthcare: A Review Of Resources From Medical Students For Size Inclusivity, Samantha Guss

VCU Libraries Faculty and Staff Publications

Medical Students for Size Inclusivity (MSSI) is a volunteer-led organization of medical students across the United States challenging weight bias in healthcare and advocating for equitable, weight-inclusive care (https://sizeinclusivemedicine.org). Recently MSSI has developed three “informed consent resources” about intentional weight loss interventions, focusing on glucagon-like peptide-1 (GLP-1) receptor agonist medications (such as Ozempic©), bariatric surgery, and pediatric weight management. The three resources are grounded in weight-neutral care and are designed to supplement information from healthcare providers by sharing more nuanced information about the research on the interventions, potential alternatives, and approaches to health that are not focused on body weight. …

Neuron-Enriched Extracellular Vesicle Micrornas Reflect Hormonal Suppression Associated With Oral Contraceptive Use In Young Women, Amulya Chowdhory, Rebekah Frye, Roxann Roberson-Nay

Undergraduate Research Posters

Hormonal contraceptives alter hypothalamic–pituitary–ovarian (HPO) feedback, but their impact on brain-associated molecular communication remains poorly understood. Neuron- enriched extracellular vesicle (nEV) microRNAs (miRNAs), isolated from plasma, provide a minimally invasive window into brain molecular activity. This pilot study examined nEV miRNA expression in young women (ages 18–22) who were either naturally cycling or using a combined monophasic oral contraceptive (OC) pill. To identify hormonally responsive miRNAs, we calculated effect sizes (Cohen’s d) between the two groups and selected those showing large between-group differences (|d| ≥ 0.8). These miRNAs were entered into a principal component analysis (PCA) to reduce dimensionality, and …

Bridging The Gap: Why Circulating Micrornas Have Yet To Become Clinical Biomarkers For Endometriosis, Anisha Addepalli, Mary C. Boyes

Undergraduate Research Posters

Endometriosis is a chronic inflammatory disorder in which endometrial-like tissue grows  outside the uterus, leading to pelvic pain, infertility, and diagnostic delays due to the current  reliance on invasive laparoscopy. Although imaging and hormonal assays offer limited accuracy in diagnosing the disease, circulating microRNAs (miRNAs) in arterial blood have emerged as a  promising alternative method as noninvasive biomarkers because they regulate gene expression,  reflect inflammatory and angiogenic pathways, and remain stable in circulation. I propose  investigating miRNAs such as miR-17-5p, miR-451a, and the let-7 family because of their direct  involvement in the regulation of processes such as cell proliferation, immune …

Establishment Of A Conditionally Replicating Guinea Pig Cytomegalovirus Model For Molecular Characterization Of Latency, Akshay R. Molakalapalli, Saketh Majeti, Michael A. Mcvoy, Jian Ben Wang

Undergraduate Research Posters

Human cytomegalovirus (HCMV) is a member of the Herpesviridae that establishes life-long latent infections that pose risks of life-threatening disease upon reactivation in immunocompromised individuals. Understanding the molecular mechanisms that govern the latent state is critical for developing effective treatments. However, molecular characterization has been impeded by the scarcity of latently infected cells in vivo and the inability of current in vitro models to support the expansion of clonal latent cell lines. To address these limitations, we developed a novel cell culture model utilizing a conditionally replicating guinea pig cytomegalovirus, a relative of HCMV that mimics HCMV pathology and provides …

A Framework For Digital Energy Modulation And Translation In Projectional X-Ray Imaging, Richard R. Wargo

Theses and Dissertations

In projectional X-ray imaging, acquisition energy fundamentally influences subject contrast, image noise, and radiation dose. While dual-energy techniques exploit spectral differences to optimize contrast and enable material separation, acquiring multiple images of the same anatomy often requires additional exposures and increased system complexity.

This dissertation presents a framework for digital energy modulation (DEM), in which computational models are trained to translate projection images between energy domains without requiring additional X-ray acquisitions. DEM is conceived as a generalizable strategy for controlled contrast modulation in projection imaging, with potential applications in image optimization, radiation therapy alignment, and dual-energy applications.

The framework was …

Generating Synthetic Ct From Mri Data, Foysal Ahmed

Theses and Dissertations

Magnetic resonance imaging (MRI) provides excellent soft tissue contrast without ionizing radiation, making it a strong alternative to computed tomography (CT) in medical imaging workflows. However, CT remains essential for applications requiring electron density information, such as radiation therapy treatment planning. This study investigated the feasibility of generating synthetic CT (sCT) images from MRI using a deep learning-based U-Net architecture. A two-dimensional U-Net was trained on paired MRI-CT data from the SynthRAD 2025 dataset, consisting of 120 T1-weighted (T1W) and 60 T2-weighted (T2W) axial cases, including deformed CT (dCT) aligned to MRI. Model testing used an independent dataset of 30 …

Magnetic Resonance Only Planning Validation Using Synthetic Ct By Mvision, Eric D. Brass Sr

Theses and Dissertations

Problems: Adaptive radiotherapy requires clinically practical methods for responding to patient-anatomy changes that occur between the original planning images and the day of treatment delivery. Registering a previously acquired computed tomography scan to a newly acquired magnetic resonance image can introduce cross-modality uncertainty and may delay replanning. This thesis evaluates whether synthetic computed tomography generated from same-day magnetic resonance imaging can reduce registration-related uncertainty while supporting rapid dose recalculation for fraction-level adaptation.

Procedure: Magnetic resonance imaging DICOM data were exported from the ViewRay MRIdian treatment planning system and uploaded to MVision for synthetic computed tomography generation. The synthetic computed tomography …

Antiestrogens As Bone Protective Therapeutics For Estrogen Receptor-Positive Breast Cancer In The Presence Of Osteoporosis, Faith E. Parker, Emily K. Zboril, David C. Boyd, Rachel Myrick, J. Chuck Harrell

Undergraduate Research Posters

Breast cancer (BC) is one of the most significant causes of mortality among women and the second leading cause of cancer death in women. The estrogen receptor (ER) is a key oncogenic driver in the majority of breast cancer. ER+ BC is the most common molecular subtype of BC. Management of ER+ breast cancer varies depending on menopausal status. For premenopausal women, the goal is to suppress estradiol production from the ovaries with surgical oophorectomy and/or aromatase inhibitors. In postmenopausal women, endocrine therapy (ET) serves to suppress estradiol production from sources other than the ovaries. During the menopausal transition, estradiol …

The Importance Of Hippotherapy: Improving The Lives Of The Disabled Through Alternative Therapy, Jennifer N. Stapleton

Undergraduate Research Posters

For centuries, horses have been suggested as “healers” and “helpers,” although it wasn’t until the 1900s that horseback riding was scientifically proven as a treatment and rehabilitation method. The exploitation of hippotherapy, the implementation of the three-dimensional pelvic movement stimulated by the oscillation and gait of the horse to combat symptoms of diseases and disorders, has since become a flourishing field of study, but one that is often overlooked. Benefits of hippotherapy often include increased motor neuron function, facilitating proper anatomical alignment, and reducing spasticity. This research analyzes the diverse and dynamic nature of treatment that hippotherapy facilitates, exploring the …

The Myopia Epidemic: Integrating Genetic, Environmental, And Epigenetic Pathways To Define A Critical Window For Intervention, Pranavika Balaji

Undergraduate Research Posters

Myopia, or nearsightedness, has increased rapidly worldwide and is now a major public health concern caused by both genetic and environmental factors. Current understanding shows that too much near work, limited time spent outdoors, and prolonged screen use contribute to abnormal eye growth in individuals who may already have a genetic predisposition. At the molecular level, epigenetic changes and shifts in DNA activity, often influenced by environmental conditions, affect the signaling pathways that regulate eye development and may help explain why myopia is increasingly common among children. This paper synthesizes recent environmental, genetic, and epigenetic research to explain how these …

Determining Genes Involved In Recovery From Chemotherapy In 4t1, Emt6, And Eo771 Breast Cancer Cells, Akash Jagdeesh, Joseph Landry Ph.D.

Undergraduate Research Posters

Breast cancer is one of the most common types of cancer, and often has poor prognosis. Traditional treatments for breast cancer include chemotherapy, which involves a chemical attack on all growing cells within the body. However, these treatments are not 100% effective, and patients might experience recurrence in their cancer months or years after achieving remission. Cancer cells can evade chemotherapy through five mechanisms: senescence, quiescence, cytoprotective autophagy, and apoptosis/necroptosis suppression. Prior studies have conducted CRISPR screens and experiments involving inhibition of epigenetic regulators, to alter the regulation of genes that can contribute to breast cancer chemotherapy resistance. This study …

Gz17.602, A Combination Of Three Nutraceuticals, Interacts With Carboplatin And Etoposide To Kill Neuroblastoma, Michael R. Booth

Theses and Dissertations

This study examined the efficacy of GZ17.602, a combination of Harmine, Isovanillin, and Curcumin as a therapeutic for MYCN-amplified Neuroblastoma, both alone and in combination with standard of care chemotherapeutics. This was done due to the low survival rate associated with these neuroblastomas, the large degree of morbidity associated with current treatments, previous experiments in the Dent lab having shown 602 as effective for killing cancers of other types, and the current lack of understanding of the biology of GZ17.602 in solid pediatric cancers. Due to the GZ17.602 components being present at different concentrations in tumors than those administered, the …
