Familial dysautonomia (FD) is a rare genetic neurodevelopmental and neurodegenerative disorder. In addition to the autonomic and peripheral sensory neuropathies that challenge patient survival, one of the most debilitating symptoms affecting patients' quality of life is progressive blindness resulting from the steady loss of retinal ganglion cells (RGCs).Within the FD community, there is a concerted effort to develop treatments to prevent the loss of RGCs. However, the mechanisms underlying the death of RGCs are not well understood. To study the mechanisms underlying RGC death, Pax6-cre;Elp1loxp/loxp male and female mice and postmortem retinal tissue from an FD patient were used to …

The Auxotrophic Formate (For) Mutant Of Neurospora Crassa Has Significantly Delayed Growth But A Normal Circadian Clock, Ziyan Wang, Kristin M. Lindgren, Jennifer J. Loros, Jay C. Dunlap
Fungal Genetics Reports
Some cell biological studies of Neurospora crassa have been limited by the rapid rates of hyphal growth and fusion. In this study, we investigated the causative mutation in the standard C24 allele of for (FGSC #9) and assayed the growth and circadian phenotype of the for strain under different nutritional conditions. We show that the for strain can be maintained as metabolically active single cells for 2 days before its growth advances into branched mycelia. This culturing system offers the potential to advance subcellular dynamic research and to facilitate greater understanding of N. crassa in the early developmental stages.

Pharmacy Faculty Articles and Research
Ubiquitin-specific protease-7 (USP7) is an important drug target as it regulates multiple proteins and genes (such as MDM2 and p53) with roles in cancer progression. Its inhibition can hinder the function of oncogenes, increase tumor suppression, and enhance immune response. The current study was designed to express USP7 in a prokaryotic system, followed by screening of small molecules against it using biophysical methods, primarily STD-NMR technique. Among them, 12 compounds showed interaction with USP7 as inferred from NMR-based screening. These compounds further caused destabilization of USP7 by reducing its melting temperature (Tm) up to 6 °C in …
Ferroptotic Cardiomyocytes Regulate Angiogenesis In The Regenerative Mouse Heart After Myocardial Infarction Through Direct And Indirect Mechanisms, Rebecca Stairey
Ferroptotic Cardiomyocytes Regulate Angiogenesis In The Regenerative Mouse Heart After Myocardial Infarction Through Direct And Indirect Mechanisms, Rebecca Stairey
MUSC Theses and Dissertations
Cardiovascular diseases (CVDs) are the leading cause of death in the United States, and heart attack occurs every 40 seconds in the US. A myocardial infarction (MI), or heart attack, results in ischemic injury and cardiomyocyte (CM) death. Mature mammalian CM renewal in the heart is insufficient to repopulate the lost tissue. However, the neonatal mouse heart retains its regenerative capacity through the first week of life, providing a valuable model to identifying regenerative factors.
Recent work by our lab revealed that the main mechanism of CM death in the heart post-MI is ferroptosis. In this study, we investigate the …

Electric Potential Energy Optimized 3d Radial Sampling Trajectories For Mri, Christopher Huynh, Datta Singh Goolaub, Christopher K Macgowan
Faculty and Staff Publications
A novel method for creating “golden” 3D center-out radial MRI sampling trajectories was developed and analyzed. This method, called ELECTRO (ELECTRic potential energy Optimized), uses repulsive forces to minimize electric potential energy. An objective function , the electric potential energies of all subsets of consecutive readouts in a 3D radial trajectory, and its reduced form were minimized using a multi-stage optimization strategy. A metric called normalized mean nearest neighbor angular distance (NMNA) was proposed for describing distributions of points on a sphere. ELECTRO and other relevant golden trajectories were compared in silico using NMNA and point spread function analysis. Consecutive …
Hepatic Targets To Control Blood Glucose And Potentially Aid In The Treatment Of Diabetes, Rena A. Velissarios
Hepatic Targets To Control Blood Glucose And Potentially Aid In The Treatment Of Diabetes, Rena A. Velissarios
PANDION: The Osprey Journal of Research and Ideas
Maintaining glucose homeostasis is extremely important to remain in good health and prevent disease. This homeostasis is achieved via the regulation of hepatic metabolic pathways like gluconeogenesis and glycogenesis by insulin, which is expressed during high blood glucose. Insulin is responsible for facilitating the uptake of glucose into other tissues from the blood, as well as signaling whether to stimulate or slow glucose metabolism in the liver. Hyperglycemia is one of the main effects of diabetes, a disease characterized by the body’s inability to produce or respond to insulin. Without insulin, hepatic glucose output continues and blood glucose accumulates, causing …
Understanding The Influence Of Bone Marrow Endothelial Cells On Primary Human Megakaryocytic-Erythroid Progenitor Cell Fate, Vedaamrutha Reddy
Understanding The Influence Of Bone Marrow Endothelial Cells On Primary Human Megakaryocytic-Erythroid Progenitor Cell Fate, Vedaamrutha Reddy
Holster Scholar Projects
The human bone marrow is a complex microenvironment comprised of hematopoietic, stromal, and bone marrow endothelial cells (BMECs). This study builds on previous findings to explore the regulatory role of BMECs in influencing the expansion and lineage choice of megakaryocytic-erythroid progenitors (MEPs). Understanding these interactions has the potential to advance transfusion medicine and improve treatments for conditions like thrombocytopenia and anemia. Due to complications with isolating human BMEC, we transitioned to a murine model. Murine BMECs were isolated and magnetic cell separation was employed to enrich for endothelial cells (ECs), which were then cultured over a 20-day period using standard …
Characterization Of Developmentally Downregulated Nfe2l3 In Retinal Ganglion Cell Survival And Axon Regeneration, Lucy Homer
Holster Scholar Projects
Retinal ganglion cells (RGCs) are central nervous system projection neurons essential for transmitting visual information from the eye to the brain. Damage to RGCs, caused by conditions such as glaucoma and traumatic optic neuropathy (TON), may lead to vision loss or blindness, as adult RGCs lack regenerative capacity. This study focuses on Nfe2l3 (Nrf3), a developmentally downregulated transcription factor known to mediate cellular responses to oxidative stress, a key pathological event following optic nerve injury. We hypothesized that overexpressing Nfe2l3 in RGCs would enhance their survival and promote axon regeneration after optic nerve crush (ONC) injury. To test this, we …

Identification Of Inflammatory Factors Contributing To Foaming In Atherosclerosis, Kavya Podila
Holster Scholar Projects
According to the National Institute of Health (NIH), atherosclerosis is attributed to the majority of cardiovascular disease (CVD) cases and is the leading cause of mortality in the US and worldwide. Despite significant medical advancements, the risk of cardiovascular events remains, warranting further mechanistic and pathogenic investigation. Advances in high-resolution omics profiling and the development of novel data-analytic bioinformatic tools previously enabled the novel discovery of two distinct programs in foaming, the central process in atherogenesis. The programs are pathogenic and homeostatic foaming, with the pathogenic foaming program being positively associated with disease. Using single-cell RNA sequencing (scRNA-seq) data from …

Development And Quantification Of An Attachment Assay For Epidermal Cells To Varying Extracellular Matrix Dilutions, Julian Vargas '26, Colleen L. Doçi
Annual Student Research Poster Session
The concept of cellular attachment is cells interacting with the extracellular matrices surrounding it. Extracellular matrices are made of various components, and it has been shown that the interactions differ between different classes of extracellular matrices. The basement membrane plays a critical role in the structure and function of the epidermis, the outermost layer of the skin. It is composed of key extracellular matrix components, which are crucial for structural stability of the skin and for maintaining the integrity of the epidermis. Through components like collagen, laminin, and proteoglycans, the BM facilitates communication between the epidermal cells and the connective …

Molecular Targets For Breast Cancer Therapy, Hamidreza Montazeri Aliabadi
Pharmacy Faculty Articles and Research
"Breast cancer is by far the most common cancer in women, and for a while, it surpassed lung cancer as the most diagnosed cancer, regardless of gender, in 2020 [1]. Chemotherapy and hormone therapy are still the first line of treatment, despite extensive research in molecularly targeted drugs. Therefore, triple negative breast cancer (TNBC) is still known as the most challenging type for treatment due to the limited identified targets. Inherent and acquired resistance are still major hurdles in breast cancer therapy, which further highlights the importance of identifying new molecular targets in this battle. The inherent resistance of unresponsive …

Enhanced Bmp Signaling Via Alk2 In Osteoclasts Decreases Bone Density In Mice, Yolanda V. Gutierrez, Hiroyuki Yamaguchi, Yuji Mishina, Yoshihiro Komatsu
Research Colloquium
Bone remodeling is a complex biological process that has been extensively studied. Bone Morphogenetic Proteins (BMPs) are recognized as one of the critical growth factors that coordinate bone remodeling. Previous studies have demonstrated that BMP signaling in osteoclasts has a positive effect on osteoclast function. However, little is known about how each BMP type I receptors control osteoclastogenesis. To investigate this question, we utilized the Cre-LoxP system to specifically activate BMP signaling through ALK2 in mice. We utilized Cathepsin K (Ctsk)-Cre driver to activate BMP signaling in osteoclasts in mice. Compared with aged- and gender-matched controls, gain-of-function of BMP mutant …

Research Colloquium
Background: Pancreatic cancer (PanCa) is the fourth deadliest cancer worldwide and expected to become the second deadliest cancer by 2030. In the USA, the National Cancer Institute put forth a grim prediction stating that there will be 64,050 new cases in 2023 alone and about 50,000 of these patients will die. The first line treatment for pancreatic cancer is Folfrinox, a three-drug regimen consisting of 5-Fluorouracil, irinotecan, and oxaliplatin. The second line treatment is gemcitabine combined with paclitaxel. Only 19% of patients who are prescribed the former regimen survive past 18 months of treatment while just 6% of patients survive …

Journal of the South Carolina Academy of Science
Chemical byproducts produced by surrounding industrial complexes have polluted the local estuaries of Georgetown, South Carolina for several decades1. Previous studies completed by the EPA and SCDNR showed that the estuaries contained carcinogenic pollutants released from the local manufacturing plants1. One of the mentioned pollutants was dioxins which are produced during the paper bleaching process2. Dioxins are highly toxic compounds that have various carcinogenic effects on the organisms that inhabit the area. These previous studies were conducted over thirty years ago. Therefore, a current study to determine if chemical byproducts are contaminating local estuaries …

Combination Therapy Of Ido1 Inhibition And Anti-Pd1 Mediates Anti-Tumor Immunity By Promoting Memory Immunity Development And Cytotoxicity Of Γδ T And Nk Cells Via Il-2 Signaling And By Overcoming Pro-Tumor Effects Of Tgf-Β Signaling, Hyuk Jee
Dartmouth College Master’s Theses
Cutaneous melanoma is the most aggressive form of skin cancer even though it takes only about 1% of all skin cancers. Even among all cutaneous melanomas, NRAS-mutant melanoma is more aggressive than any other, and about 10-25% of all cutaneous melanoma cases have mutations in NRAS. NRAS is a member of the RAS family of proto-oncogenic GTPase proteins, and it plays a key role in signal transduction pathways responsible for cellular survival, proliferation, and metabolism. Immunotherapy is the first line of defense against NRAS-mutant melanoma because, despite tremendous efforts made for decades, it has not been successful to develop small …
Emerin Deficiency Drives Mcf7 Cells To An Invasive Phenotype, Emily Hansen, Christal Rolling, Matthew Wang, James M Holaska
Emerin Deficiency Drives Mcf7 Cells To An Invasive Phenotype, Emily Hansen, Christal Rolling, Matthew Wang, James M Holaska
Rowan-Virtua School of Osteopathic Medicine Departmental Research
During metastasis, cancer cells traverse the vasculature by squeezing through very small gaps in the endothelium. Thus, nuclei in metastatic cancer cells must become more malleable to move through these gaps. Our lab showed invasive breast cancer cells have 50% less emerin protein resulting in smaller, misshapen nuclei, and higher metastasis rates than non-cancerous controls. Thus, emerin deficiency was predicted to cause increased nuclear compliance, cell migration, and metastasis. We tested this hypothesis by downregulating emerin in noninvasive MCF7 cells and found emerin knockdown causes smaller, dysmorphic nuclei, resulting in increased impeded cell migration. Emerin reduction in invasive breast cancer …

Emerging evidence suggests a significant contribution of primary cilia to cell division and proliferation. MicroRNAs, especially miR-17, contribute to cell cycle regulation and proliferation. Recent investigations have highlighted the dysregulated expression of miR-17 in various malignancies, underlining its potential role in cancer. However, the correlation between primary cilia and miR-17 has yet to be fully elucidated. The present study examines the presence of miR-17 in primary cilia. The miR-17 expression is studied in selected ciliary protein knockdown cells. Using in situ hybridization (ISH), we identified the subcellular localization of miR-17 in both cilium and cell body. We confirmed the importance …

Kindlin-2 is a cytoskeletal adapter protein that is present in many different cell types. By virtue of its interaction with multiple binding partners, Kindlin-2 intercalates into numerous signaling pathways and cytoskeletal nodes. A specific interaction of Kindlin-2 that is of paramount importance in many cellular responses is its direct binding to the cytoplasmic tails of integrins, an interaction that controls many of the adhesive, migratory and signaling responses mediated by members of the integrin family of cell-surface heterodimers. Kindlin-2 is highly expressed in many cancers and is particularly prominent in prostate cancer cells. CRISPR/cas9 was used as a primary approach …

A Bioinformatics Approach To Understanding The Pathogenesis Of Ectopic Spine Calcification, Fang Chi Wang
Electronic Thesis and Dissertation Repository
This study used mice lacking equilibrative nucleoside transporter 1 (ENT1-/-) as a preclinical model to study pathogenesis of ectopic spine mineralization in diffuse idiopathic skeletal hyperostosis (DISH). We hypothesized that mineralization of the annulus fibrosus (AF), was driven by dysregulation of cellular processes and pathways associated with apoptosis, S100A9 proteins, the PI3K-Akt pathway, and lipid metabolism. Target pathways and processes were assessed using in situ localization and quantitative analyses. Metabolomic analysis of AF and plasma data was conducted to identify altered metabolites. Results demonstrate increased caspase-3 activity in the AF of ENT1-/- mice at both timepoints …

Overexpression and aberrant activation of signal transducer and activator of transcription 3 (STAT3) contribute to tumorigenesis, drug resistance, and tumor-immune evasion, making it a potential cancer therapeutic target. BP1003 is a neutral liposome incorporated with a nuclease-resistant P-ethoxy antisense oligodeoxynucleotide (ASO) targeting the STAT3 mRNA. Its unique design enhances BP1003 stability, cellular uptake, and target affinity. BP1003 efficiently reduces STAT3 expression and enhances the sensitivity of breast cancer cells (HER2+, triple negative) and ovarian cancer cells (late stage, invasive ovarian cancer) to paclitaxel and 5-fluorouracil (5-FU) in both 2D and 3D cell cultures. Similarly, ex vivo and in …
Regulation Of Sterile Inflammatory Responses By Mitochondria-Associated Proteins, Meghana Venkatesan
Regulation Of Sterile Inflammatory Responses By Mitochondria-Associated Proteins, Meghana Venkatesan
Master's Theses
Inflammation is an important defense mechanism through which cells respond to pathogenic insults and damage/stress signals. Immune cells mediate extracellular inflammatory responses by synthesizing and releasing small proteins called cytokines, which play critical roles in modulating these responses. Specifically, key pro-inflammatory cytokines such as IL-1beta are released upon the assembly and activation of a multi-protein intracellular complex called the inflammasome, the most well-studied of which is the NLRP3 inflammasome. Several proteins have been identified as important regulators of cellular stress responses, including vacuole membrane protein 1 (VMP1). The present research shows that VMP1-depleted cells exhibit exacerbated cellular inflammation and are …

Delivering nucleic acid therapeutics across cell membranes is a significant challenge. Cell-penetrating peptides (CPPs) containing arginine (R), tryptophan (W), and histidine (H) show promise for siRNA delivery. To improve siRNA delivery and silence a model STAT3 gene, we hypothesized that oleyl acylation to CPPs, specifically (WRH)n, would enhance STAT3 silencing efficiency in breast and ovarian cancer cells. Using Fmoc/tBu solid-phase peptide chemistry, we synthesized, purified, and characterized the oleyl-conjugated (WRH)n (n = 1–4) peptides. The peptide/siRNA complexes were non-cytotoxic at N/P 40 (~20 μM) against MDA-MB-231, MCF-7, SK-OV-3, and HEK-293 cells after 72 h incubation. All peptide/siRNA complexes showed serum …
