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 …

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. …

Faculty, Staff and Students Publications

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 …

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 …

The immune system is not only essential for host defense, but it is also involved in tissue maintenance and disease pathogenesis. Macrophages play a key role in tissue repair, fibrosis, and tumorigenesis, but the mechanisms underlying their multifunctionality have not been fully explored. Here, we identified Mrep (Ly6ChiCX3CR1loPDPN+CD9+) as a crucial subset of macrophages for muscle regeneration after muscle injury. Muscle regeneration required Mrep-derived activin A, which was produced via the TLR4/TIR domain-containing adapter-inducing interferon-β/TANK-binding kinase 1/interferon regulatory factor 3/7 signaling pathway in response to muscle injury. Mrep exerted pathological effects by secreting activin A in a model of genetically …

Concurrent Vulvar Vitiligo And Lichen Sclerosus: The Importance Of Melanocyte-Specific Immunostains In Resolving Diagnostic Ambiguity, Nabor S Mireles, Kaitlyn Levett, Annie Dai, Abdul Hafeez Diwan, Omid Jalali

Faculty, Staff and Students Publications

Vitiligo and lichen sclerosus (LS) are autoimmune dermatoses that may share overlapping clinical and histopathologic features, posing diagnostic challenges when they occur concurrently. We report a biopsy-confirmed case of vulvar vitiligo and LS in a 61-year-old woman presenting with pruritic, depigmented patches on the labia majora and minora. Histopathologic examination showed epidermal thinning with papillary dermal hyalinization and a dense, band-like lymphocytic infiltrate consistent with LS. Melan-A immunostaining demonstrated a complete absence of epidermal melanocytes, confirming concurrent vitiligo rather than LS-related post-inflammatory hypopigmentation. This case underscores the importance of correlating subtle clinical clues with melanocyte-specific immunostains to distinguish coexistent vitiligo …

Neuroendocrine prostate cancer (NEPC) is a highly aggressive and lethal subtype of prostate cancer (PCa) that often emerges in response to androgen receptor pathway inhibitors (ARPIs), which are widely used in treating metastatic castration-resistant and hormone-sensitive prostate cancer. The incidence of NEPC is increasing, yet effective therapeutic strategies remain limited due to an incomplete understanding of its molecular drivers. Through transcriptomic analyses of human prostate tumor samples, we identified the histone lysine demethylase KDM4A as uniquely overexpressed in human and mouse NEPC compared to prostate adenocarcinoma. Functional validation demonstrated that KDM4A is a key regulator of NEPC progression and a …

Losartan-Induced Angioedema: A Case Report And Review Of Literature, Leila C. Tou, Audrey Nourse, Rachel Cox, Spencer Stanford

Journal of Community Hospital Internal Medicine Perspectives

Angiotensin receptor blockers (ARBs) are frequently prescribed as alternatives to angiotensin-converting enzyme inhibitors (ACEIs), particularly in patients who experience ACEI-induced adverse effects including cough. Although ARBs are associated with a lower incidence of angioedema, rare cases have been reported in patients without prior ACEI exposure. Here, we describe a 58-year-old Black male who developed lip and facial swelling six months after starting losartan. His symptoms did not improve with antihistamines or corticosteroids but resolved after discontinuation of losartan, which was replaced with amlodipine without recurrence. This case emphasizes the need for clinician awareness of ARB-induced angioedema and the importance of …
