Expression, Characterization, And Comparative Analysis Of Bacillus Bacteriophage Endolysins, Stephen D. Zdgiebloski

Research and Creativity Symposium

Bacteriophages present a promising alternative for combating antibiotic-resistant bacteria without disrupting the normal microbiome or harming human cells. The antibacterial properties of lytic bacteriophages are largely attributed to endolysins, enzymes active in the lytic cycle. Endolysins recognize bacterial cell walls and cleave the peptidoglycan matrix, leading to cell wall disruption. Their specificity and effectiveness against bacterial hosts are determined by two functional domains, including the cell wall binding domain. Our research focuses on characterizing Bacillus phage endolysins. We analyzed the protein sequences of endolysins from six Bacillus phages isolated at the University of Mary Washington. Although these phages were isolated …

Metabolic And Microbial Crossroads: Sodium-Glucose Cotransporter-2 Inhibitors And Urinary Tract Infections In (Asian) Diabetes Care, Rob E. Carpenter

Human Resource Development Faculty Publications and Presentations

The global rise of type 2 diabetes, particularly in Asian populations, has led to widespread adoption of sodium-glucose cotransporter-2 (SGLT2) inhibitors for glycemic control. While effective, these agents elevate the risk of urinary tract infections (UTIs) by inducing glycosuria, which creates a nutrient-rich environment that favors uropathogen growth. Asian individuals may be disproportionately vulnerable to SGLT2 inhibitor–associated UTIs due to a confluence of factors, including lower body mass index, increased visceral adiposity, congenital urinary tract anomalies, and genetic polymorphisms that impair uroepithelial integrity and immunity. This review integrates emerging evidence on the molecular, anatomical, and immunometabolic mechanisms that underlie infection …

Background: Undifferentiated pleomorphic sarcoma (UPS) is the largest subgroup of soft-tissue sarcomas. It demonstrates post-therapeutic hemosiderin deposition, granulation tissue formation, fibrosis, and calcification. Our research aims to establish the multiparametric MRI (mp-MRI) value for predicting UPS treatment response.

Methods: An IRB-approved retrospective study included 33 extremity UPS patients with pre-operative mp-MRI, including diffusion-weighted imaging (DWI), contrast-enhanced susceptibility-weighted imaging (CE-SWI), and perfusion-weighted imaging with dynamic contrast-enhancement (PWI/DCE), and surgical resection between February 2021 and May 2023. Lesions were visually classified on CE-SWI into one of 6 morphology patterns. On PWI/DCE, lesions were classified into one of 6 patterns, and time-intensity curves …

Ecology Of Beech Leaf Disease: Identifying The Forest Conditions Correlated With Infection In Northeast Ohio, Blake Logan

Research Symposium

Beech Leaf Disease (BLD) is a novel, poorly-understood threat to forests across North America. Since its discovery in northeast Ohio in 2012, the disease has affected staggering numbers of beech trees (Fagus grandifolia), resulting in increased sapling mortality. In the near future, mortality in symptomatic mature trees is expected to follow. The symptomatic striped leaves result from the activity of the nematode Litylenchus crenatae ssp. mccannii, but the precise role this organism plays in transmission and infection is currently unknown.

Oberlin College has been conducting forest demography research at Chance Creek, a nature preserve in Lorain county, since 1974. Every …

The Oberlin College Global Health Concentration has played a crucial role in helping me strengthen my personal goals and professional vision, especially regarding the future I hope to shape for others. Before attending Oberlin, I knew I wanted to pursue a career in nursing, driven by both positive and negative experiences that my family, my communities, and I have encountered within the healthcare system. These experiences motivated me to acquire the necessary knowledge and skills to create a more equitable, accessible, and intentional healthcare environment for underrepresented communities. Throughout my time at Oberlin, I’ve been learning to think critically about …

Effects Of Pfos On Zebrafish Dopaminergic Neurodevelopment, Allison G. Fletcher

Research and Creativity Symposium

Per- and polyfluoroalkyl substances (PFAS) are a group of environmental contaminants that cause disruptions to the nervous and endocrine systems. Perfluorooctanesulfonate (PFOS) is considered one of the most disruptive PFAS to the nervous system, and may disrupt neurodevelopment of the dopaminergic system, which has been linked to neurodevelopmental disorders like Attention Deficit/Hyperactivity Disorder (ADHD) in humans. I hypothesized that early life PFOS exposure disrupts the development of the dopaminergic system. To test this hypothesis, I exposed zebrafish to 0.05, 0.5, and 5.0 mg/L PFOS through 5 days of embryonic and larval development. To assess acute effects of PFOS on the …

From Dysbiosis To Dysfunction: Investigating The Effects Of Chronic Cocaine Use On Oral Microbial Shifts And Neuropathogenesis, Douglas E. Johnson

MUSC Theses and Dissertations

Cocaine use disorder remains a significant public health challenge. However, the mechanisms by which chronic cocaine use contributes to neuroinflammation and cognitive decline are still not fully understood. Chronic non-intravenous cocaine use is associated with oral microbial dysbiosis. Although the gut-brain axis has been widely studied, the impact of cocaine-mediated shifts on the oral microbiome on systemic and neuroinflammation remains a significant yet largely unexplored gap. This dissertation investigates the hypothesis that cocaine-specifically enriched oral Streptococcus parasanguinis triggers neuroinflammation, neuropathology, and cognitive deficits. In a human study, the saliva microbiomes from chronic cocaine users exhibited reduced α-diversity, enriched Streptococcus genus, …

Frequent Failure Of Nutrients To Increase Plant Biomass Supports The Need For Precision Fertilization In Agriculture, Oliver H. Carroll, Eric W. Seabloom, Elizabeth T. Borer, W. Stanley Harpole, Peter Wilfahrt, Carlos A. Arnillas, Erika Hersh-Green, Et. Al.

Michigan Tech Publications

Implementing precision fertilization to maximize crop yield while minimizing economic and environmental impacts has become critical for agriculture. Variability in biomass response to fertilization within fields, among regions, and over time creates simultaneous risks of under-yielding and overfertilization. We quantify factors determining fertilization responsiveness (i.e., biomass increases with fertilization) up to 15 years in 61 unfertilized rangelands on six continents. We demonstrate widespread multi-year variability in responsiveness, with fertilization increasing average yield by 43% but failing to improve biomass 26% of the time. All sites were responsive at least once, but only four of 61 responded in all plots and …

Results: DNA damage in lymphocytes occurred at uric acid concentrations of ≥600 μM. Adding catalase to the uric acid solution diminished the damaging effect, indicating that hydrogen peroxide mediated the prooxidant activity. Moreover, …

Intrinsic Apoptotic Effect Of Anatolian Honeybee (Apis Mellifera Anatoliaca) Venom Promoted With Mesoporous Silica Nanocarriers, Batuhan Orman, Ayli̇n Koç, Di̇dem Şen Karaman, Ayşe Nalbantsoy

Turkish Journal of Biology

Background/aim: The use of bee products or treatment with bees, as a complement to conventional medicine is attracting considerable attention in cancer research. Although discoveries related to the potential anticancer effects of bee venom are increasing, the unstable nature of venom biomolecules remains a limiting factor for their usage. In this study, we employed mesoporous silica nanocarriers (MSNs) to provide precise dosing and prevent carriers from biomolecule degradation thanks to the outstanding loading capacity provided by the pores, excellent chemical and biological robustness, and ability to improve bioavailability.

Materials and methods: MSNs were synthesized and physicochemical characterizations were …

N-Cadherin Mimetic Hydrogels Drive Superior Regenerative And Paracrine Responses In 3d Cultures Of Adipose-Derived Mesenchymal Stem Cells, Demet Kaçaroğlu, Alper Murat Ulaşli, Aybüke Di̇denur Sak, Seher Yaylaci

Turkish Journal of Biology

Background: Cadherin-based biomaterials play a pivotal role in influencing the fate of mesenchymal stem cells (MSC). Enhancing the adhesion of adipose tissue-derived MSCs has been shown to augment their paracrine effects while N-cadherin biomaterials have been suggested to regulate the paracrine effects of MSCs via specific growth factors although the precise mechanisms underlying this regulation remain insufficiently understood. This study aims to compare the effects of a 3D N-cadherin mimetic environment on cell viability, apoptosis, extracellular matrix regulation, and growth factor expression with those observed in traditional 2D and 3D spheroid cultures. Additionally, the study seeks to evaluate the …

Knockdown Of Plexin C1 Induces Epithelial-To-Mesenchymal Transition And Confers Resistance To Multikinase Inhibitors In Hepatocellular Carcinoma Cells, Gamze Güngör Topcu, Arzu Aysan, Şevval Di̇k, Mai̇de Şeker, Meli̇ke Bi̇nnur Bahçekapili, Sude Topkaraoğlu, Di̇lek Yavuzer, Tamer Yağci

Turkish Journal of Biology

Background/aim: HCC is a common and lethal malignancy and multi-kinase inhibitors (MKIs) are among the therapeutic options for unresectable cases. However, response rates to MKIs remained variable, necessitating the identification of predictive biomarkers. Plexin C1 (PLXNC1), a receptor involved in cell signaling, has emerged as a potential candidate to regulate tumor responses. This study aims to evaluate the impact of PLXNC1 expression on the sensitivity of HCC cells to MKI therapy.

Turkish Journal of Biology

Background/aim: Osteosarcoma, a primary malignant bone tumor, is challenging to treat due to its aggressive nature and limited therapies. Resveratrol (RES), a natural polyphenol, has potential anticancer properties. Hence, we investigated RES’s impact on osteosarcoma cells, focusing on triosephosphate isomerase (TPI) and related mechanisms.

Materials and methods: RES was applied to osteosarcoma (SaOS-2) and healthy fetal osteoblast (hFOB 1.19) cells for 48 h, and cell viability was measured by SRB assay. The mode of cell death was examined using Hoechst 33342/annexin V/propidium iodide. TPI and methylglyoxal (MG) enzyme levels were determined by ELISA. The effect of RES on …

Effects Of Soluble Electron Shuttles On Microbial Iron Reduction And Methanogenesis, Bhim Sen Thapa, Theodore M. Flynn, Zena D. Jensvold, Kenneth M. Kemner, Margaret F. Sladek, Edward J. O'Loughlin, Christopher W. Marshall

Biological Sciences Faculty Research and Publications

In many aquatic and terrestrial ecosystems, iron (Fe) reduction by microorganisms is a key part of biogeochemical cycling and energy flux. The presence of redox-active electron shuttles in the environment potentially enables a phylogenetically diverse group of microbes to use insoluble iron as a terminal electron acceptor. We investigated the impact that different electron shuttles had on respiration, microbial physiology, and microbial ecology. We tested eight different electron shuttles, seven quinones and riboflavin, with redox potentials between 0.217 and −0.340 V. Fe(III) reduction coupled with acetate oxidation was observed with all shuttles. Once Fe(III) reduction began to plateau, a rapid …

All Stressed Out: An Investigation On The Effects Of Environmental Stressors On The Northern Leopard Frog (Rana Pipiens), Ella C. Wittmuss

Honors Thesis

Corticosterone (CORT) is the primary glucocorticoid in many vertebrates, including mammals, birds, reptiles, and amphibians. When an organism is exposed to external or internal stressors, CORT levels often increase (Rich & Romero, 2005; Titon et al., 2021). An increase in CORT can cause adverse physiological effects such as slower growth, malformations in different parts of the body, and specific blood sugar diseases such as diabetes (Glennemeier & Denver, 2002; Tarlow &Blumstein, 2007). CORT levels are indicators of survival, growth, and reproduction in larval amphibians. Many species, including our model organism, the Northern Leopard Frog (Rana pipiens), are often subjected to …

Diapause And Anoxia-Induced Quiescence Are Unique States In Embryos Of The Annual Killifish, Austrofundulus Limnaeus, Patrick R. Clouser, Claire L. Riggs, Amie L. T. Romney, Jason E. Podrabsky

Biology Faculty Publications and Presentations

Diapause is a state of developmental and metabolic dormancy that precedes exposure to environmental stresses. Yet, diapausing embryos are typically stress-tolerant. Evidence suggests that diapausing embryos “prepare” for stress as part of a gene expression program as they enter dormancy. Here, we investigate if diapause II embryos of the annual killifish Austrofundulus limnaeus, which can survive for hundreds of days of anoxia, can mount a transcriptomic response to anoxic insult. Bulk RNAseq was used to characterize the transcriptomes of diapause II embryos exposed to normoxia, 4 h and 24 h anoxia, and 2 h and 24 h normoxic recovery …

Studies To Understand The Stability And Liabilities Of Legumain-Cleavable Antibody-Drug Conjugates, Michele Yi

Undergraduate Honors Theses

Antibody-drug conjugates (ADCs) offer targeted drug delivery of potent cytotoxic payloads, minimizing systemic toxicity. However, the stability of the linker is integral to ensure that there is minimal off-target payload release and little systemic toxicity. This study analyzes the physical and biological stability of our new legumain-cleavable vs traditional cathepsin-cleavable antibody-drug conjugates (ADCs), with a focus on hydrophobicity, thermal stability, aggregation, and biological payload release. Our findings indicate that decreased hydrophobicity of the legumain-cleavable ADCs compared to cathepsin-cleavable ADCs is correlated with decreased aggregation (predicting lower uptake by liver macrophages and therefore slower clearance and less systemic toxicity) and lower …

Distinct Adipose Progenitor Cells Emerging With Age Drive Active Adipogenesis, Guan Wang, Gaoyan Li, Anying Song, Yutian Zhao, Jiayu Yu, Yifan Wang, Wenting Dai, Martha Salas, Hanjun Qin, Leonard Medrano, Joan Dow, Aimin Li, Brian Armstrong, Patrick T Fueger, Hua Yu, Yi Zhu, Mengle Shao, Xiwei Wu, Lei Jiang, Judith Campisi, Xia Yang, Qiong A Wang

Children’s Nutrition Research Center Staff Publications

Starting at middle age, adults often suffer from visceral adiposity and associated adverse metabolic disorders. Lineage tracing in mice revealed that adipose progenitor cells (APCs) in visceral fat undergo extensive adipogenesis during middle age. Thus, despite the low turnover rate of adipocytes in young adults, adipogenesis is unlocked during middle age. Transplantations quantitatively showed that APCs in middle-aged mice exhibited high adipogenic capacity cell-autonomously. Single-cell RNA sequencing identified a distinct APC population, the committed preadipocyte, age-enriched (CP-A), emerging at this age. CP-As demonstrated elevated proliferation and adipogenesis activity. Pharmacological and genetic manipulations indicated that leukemia inhibitory factor receptor signaling was …

Ovarian cancer is associated with high rates of patient mortality and morbidity. Laparoscopic assessment of tumor localization can be used for treatment planning in newly diagnosed high-grade serous ovarian carcinoma (HGSOC). While spread to multiple intra-abdominal areas is correlated with worse outcomes, whether other morphological tumor differences are also associated with patient outcomes is unknown. Given the large volume of visual information in laparoscopic videos, we investigated whether deep-learning models can capture implicit features and predict treatment outcomes. We developed a novel deep-learning framework using pre-treatment laparoscopic images to assess clinical outcomes following upfront standard treatment, defined as short progression-free …

Patients with high-grade serous ovarian carcinoma (HGSC) are usually diagnosed with advanced-stage disease, and the tumors often have immunosuppressive characteristics. Together, these factors are important for disease progression, drug resistance, and mortality. In this study, we used a combination of single-cell sequencing and spatial transcriptomics to identify the molecular mechanisms that lead to immunosuppression in HGSC. Primary tumors consistently showed a more active immune microenvironment than did omental tumors. In addition, we found that untreated primary tumors were mostly populated by dysfunctional CD4 and CD8 T cells in later stages of differentiation; this, in turn, was correlated with expression changes …

Acute Brcaness Induction And Ar Pathway Blockage Through Cdk12/7/9 Degradation Enhances Parp Inhibitor Sensitivity In Prostate Cancer, Fu Gui, Baishan Jiang, Jie Jiang, Zhixiang He, Takuya Tsujino, Tomoaki Takai, Seiji Arai, Celine Pana, Jens Köllermann, Gary Andrew Bradshaw, Robyn Eisert, Marian Kalocsay, Anne Fassl, Steven P Balk, Adam S Kibel, Li Jia

Faculty, Staff and Student Publications

Current treatments for advanced prostate cancer (PCa) primarily target the androgen receptor (AR) pathway. However, the emergence of castration-resistant prostate cancer (CRPC) and resistance to AR pathway inhibitors (APPIs) remains ongoing challenges. Here, we present BSJ-5-63, a proteolysis-targeting chimera (PROTAC) targeting cyclin-dependent kinases (CDKs) CDK12, CDK7, and CDK9, offering a multipronged approach to CRPC therapy. BSJ-5-63 degrades CDK12, diminishing BRCA1 and BRCA2 expression and inducing a sustained "BRCAness" state. This sensitizes cancer cells to PARP inhibitors (PARPis) regardless of their homologous recombination repair (HRR) status. Furthermore, CDK7 and CDK9 degradation attenuates AR signaling, enhancing its therapeutic efficacy. Preclinical studies, including …

Research & Creative Achievement Day

Platyhelminthes, also known as flatworms, are among the most common parasites found in North American duck species. This phylum of parasites includes tapeworms and flukes. This study focused on identifying various Platyhelminthes found in Minnesota and Wisconsin wild ducks using both morphological characteristics and genetic sequencing. Both diving and dabbling species of ducks were used for this study, including green winged-teal (Anas carolinensis) and ring-necked ducks (Aythya collaris). Platyhelminthes were removed from legally harvested ducks and stained before examining and imaging under the microscope to identify key morphologic features for a presumptive identification. Subsequently, DNA was extracted …

Development Of A Qpcr For Detecting Borrelia Burgdorferi And Ixodes Tick Dna Simultaneously, Jenna Junker, Anthony J. Appicelli

Research & Creative Achievement Day

Black-legged ticks (Ixodes scapularis) and Lyme disease, caused by the bacterium Borrelia burgdorferi, are prevalent in the upper Midwest. Accurate determination of the percentage of Ixodes ticks that carry Lyme disease could help physicians and health experts develop treatment and prevention plans to curb the prevalence of disease. The purpose of this study was to see if accurate results for both Ixodes DNA and Borrelia DNA could be analyzed in the same qPCR assay for faster Lyme disease testing. Current testing in humans is achieved by running two separate diagnostic assays, an ELISA and Western Blot, both …
