Fgfr3::Tacc3 Fusion And Notch1 Loss-Of-Function In A Case Of Hpv-Associated Sinonasal Squamous Cell Carcinoma: Diagnostic Challenge And Implications For Targeted Therapy, Xu Cao, Hong Yu, Reham Hamdy Abdulazim Soliman, Pei Ying, Songlin Zhang, Li Liang

Faculty, Staff and Students Publications

Sinonasal squamous cell carcinoma (SNSCC) comprises a heterogeneous group of tumors with emerging molecular subtypes. Human papillomavirus (HPV)-associated SNSCC is a distinct entity, although actionable genomic alterations beyond HPV-driven pathways remain underexplored. Distinguishing HPV-associated SNSCC from carcinoma ex inverted papilloma can be particularly challenging in limited biopsy specimens, as these lesions may appear morphologically similar. We report a case of HPV-associated SNSCC with concurrent FGFR3::TACC3 fusion and NOTCH1 p.C1416 stop-gain mutation.

Oncocytic Intraductal Carcinoma Of The Parotid Gland With Strn::Alk Fusion, Reham H Soliman, Chris Shi, Kevin E Fisher, Hong Yu, Fouad El-Dana, Xu Cao, Li Liang, Pei Ying, Songlin Zhang

Faculty, Staff and Students Publications

Intraductal carcinoma (IDC) of the salivary gland is an uncommon epithelial neoplasm characterized by a predominantly intraductal or intracystic proliferation rimmed by a myoepithelial cell layer. Advances in molecular profiling have revealed recurrent gene fusions in IDC, most frequently involving RET, although fusions implicating other kinase genes have also been described. Among these, ALK rearrangements are rare and remain poorly characterized. Herein, we report a case of oncocytic IDC of the parotid gland harboring a STRN::ALK fusion, further expanding the molecular landscape of this tumor. Although this fusion has been previously reported in intercalated duct IDC, to our knowledge, this …

We report the design and SAR studies of benzopyran-, benzofuran-, and benzothiophene-derived inhibitors of the retinoic acid receptor alpha (RARα) for male contraception. SAR studies identified critical features influencing activity, such as the optimal positioning of antagonism moieties and substituents, leading to the discovery of (S)-4-(5-(2,8-dimethyl-5-(p-tolyl)-2H-chromen-3-yl)-1H-pyrrol-2-yl)­benzoic acid (compound 23). Compound 23 is a highly potent RARα inhibitor (IC50 = 0.051 nM) with excellent selectivity (>1650-fold over RARβ and >1960-fold over RARγ) and ADMET properties. Compound 23 is orally bioavailable and reduces sperm counts in mice for a full male contraceptive effect …

Authors:

Alice Werynski B.S, Kang Chen Ph.D

Background:

Maternal allergies are a prevalent yet overlooked category of gestational disease. Pregnancy is characterized by a Th2 dominant immunological environment, and because many allergic diseases also rely on Th2 cytokines and IgE-mediated pathways, allergy during pregnancy may impact symptoms and influence maternal and fetal outcomes.

Methods:

This narrative review summarizes and compares literature on the prevalence of allergic conditions in pregnancy, their immunologic mechanisms, and their effects on maternal health, fetal development, and treatment safety. The search was conducted through …

Environmental Mercury Alters Immune Pathways Linked To Autoimmune Risk In Mice Mirroring Humans, Maurgan Lee, Paul Stemmer, Randall Gill, Allen Rosenspire, Anil Aranha, Heather Gibson

Medical Student Research Symposium

Background and Purpose: Mercury is a pervasive environmental contaminant, and human epidemiologic studies have linked chronic low-level exposure to increased autoimmune disease-risk. Dysregulated lymphocyte activation and impaired signaling tolerance are central mechanisms in human autoimmunity. Protein phosphorylation governs lymphocyte differentiation and function, alterations in phosphoproteomic networks may represent a signature of immune disruption. This study evaluates how low dose mercury exposure modifies B and T cell abundance and intracellular signaling patterns in BALB/c and Diversity Outbred (DO) mice.

Methods: BALB/c and DO mice were exposed to low dose HgCl2 in their water for two weeks or provided standard water controls. …

Progressive Cardiac Phenotypes And Reduced Reversibility From Long-Term Cugexp Rna Expression In A Dm1 Mouse Model, Rong-Chi Hu, Mohammadreza Tabary, Xander Ht Wehrens, Thomas A Cooper

Faculty, Staff and Students Publications

Myotonic dystrophy type 1 (DM1) is caused by an expanded CTG repeat in the DMPK gene, resulting in mutant transcripts that form expanded CUG (CUGexp) RNA foci and sequester muscleblind-like (MBNL) RNA-binding proteins. DM1 is multisystemic, with progressive worsening of disease manifestations in affected tissues. Disease progression is attributed to somatic expansion of the CTG repeats with age, resulting in production of CUGexp RNA with enhanced intrinsic toxicity due to increased MBNL sequestration. To determine the degree to which cardiac disease progression can occur independently of repeat expansion, we used a transgenic DM1 mouse model with inducible heart-specific expression of …

When Optimal Therapy Becomes High Risk: A Risk-Benefit Framework For Beta-Lactam Desensitization In Life-Threatening Mssa Infection, Rana Amoush, Aaron Kobernick

Conference Presentation Abstracts

Background Beta-lactam antibiotics are preferred for invasive methicillin-sensitive Staphylococcus aureus (MSSA) infections, especially those involving prosthetic material. Management is challenging in patients with severe beta-lactam hypersensitivity, as alternative agents may be less effective or poorly tolerated. Limited guidance exists on reassessing desensitization risk when second-line therapies become untenable. Purpose To present a case-based risk-benefit framework for evaluating beta-lactam desensitization in medically complex patients with life-threatening MSSA infections. Methods We retrospectively reviewed a patient with recurrent MSSA prosthetic graft infection and severe beta-lactam hypersensitivity. Clinical decision-making was analyzed using a structured risk–benefit framework incorporating infection severity, therapeutic superiority of beta-lactams, tolerance …

Novel Biomarker Discovery In Multiple Sclerosis, Manisha Gangasani

Honors Theses

Multiple Sclerosis (MS) is a chronic neuroinflammatory disorder affecting the brain, spinal cord, and optic nerve. Patients experience cognitive, motor, autonomic, and emotional symptoms that often overlap with other neurological conditions, making early diagnosis challenging. Current diagnostic criteria require evidence of lesions with dissemination in time and space. Racial disparities in MS outcomes are well documented, with Black individuals often exhibiting greater disease severity, higher relapse rates, and increased disability compared to White individuals. These differences likely reflect a combination of genetic, biological, environmental, and healthcare access factors, underscoring the need to improve early diagnosis and reduce inequities in care. …

Cardiac disease is a well-established manifestation of myotonic dystrophy type 1 (DM1), characterized by progressive cardiac conduction slowing with increased risk of atrial and ventricular arrhythmias, heart block, and sudden cardiac death. Multiple disease modifying therapies are in clinical trials for DM1 and show promise in improving skeletal muscle weakness and myotonia. Testing the effects of these medicines, or others, in the heart is of critical importance, but requires identification of endpoints of cardiac function that accurately reflect the state of DM1 cardiac disease. To better define cardiac endpoints, the Myotonic Dystrophy Clinical Research Network (DMCRN) and the Myotonic Dystrophy …

Versatile Smad2 And Smad3 Epitope-Tagged Mouse Models For Genomic Profiling Of Tgfβ Signaling: Uncovering Gdf9-Smad2/3 Targets, Zian Liao, Qian Zhang, Keisuke Shimada, Kaori Nozawa, Suni Tang, Masahito Ikawa, Diana Monsivais, Martin M Matzuk

Faculty, Staff and Students Publications

Transforming growth factor β (TGFβ) signaling pathways are integral for a plethora of biological processes. SMAD2 and SMAD3 are the principal transcriptional effectors of TGFβ superfamily ligands, yet quantitative, genome-wide mapping of their DNA-associated complexes under physiological contexts has remained limited due to the lack of specific, robust models. Here, we generated two versatile epitope-tagged mouse models in which endogenous SMAD2 and SMAD3 proteins are globally tagged with hemagglutinin (HA) and podoplanin (PA) sequences, respectively, enabling high-fidelity profiling of SMAD2 and SMAD3 binding across tissues. To demonstrate the broad application of our models, we exemplified the usage of our lines …

Detection And Quantification Of Allergen Cross-Contact In Shared Frying Oil Using Targeted Mass Spectrometry, Francisca Asigri

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Cow’s milk and egg allergies are prevalent IgE-mediated food allergies that pose significant public health concerns worldwide. Although strict avoidance remains the primary management strategy, unintended exposure can still occur through allergen cross-contact, particularly in commercial and industrial food operations that utilize shared frying oils. The objective of this study was to identify and quantify allergen transfer in shared frying oil and assess the robustness of existing targeted mass spectrometry methods (LC-MS/MS) for detecting milk and egg proteins in heated oil matrices.

Heated oil spikes were developed by incorporating non-fat dry milk (NFDM) and whole egg powder (WEP) into oil …

Azithromycin is a widely used antibiotic and was frequently used to treat hospitalized patients during the COVID-19 pandemic. The impact of empiric azithromycin use on the respiratory microbiome in patients with viral respiratory infections is unclear. Here we used longitudinal metatranscriptomics on nasal swabs from a prospective multicentre cohort of 1,164 patients hospitalized for COVID-19. We compared the upper respiratory microbiome, resistome and systemic immune response in patients treated with azithromycin (n = 366) with those who received no antibiotics (n = 474) or other antibiotics (n = 324). We found that azithromycin altered microbiome composition and increased the expression …
