Estrogen receptor-positive (ER+) breast cancer exhibits a marked propensity for skeletal metastasis; however, the molecular drivers of bone colonization remain incompletely defined. We investigated the tumor suppressor neurofibromin (NF1), a dual repressor for RAS and ER signaling, whose inactivation promotes endocrine therapy (ET) resistance and is associated with inferior relapse-free survival. NF1 copy number loss was detected in 62% of ER+ patients who subsequently developed metastases and was associated with an increased likelihood of bone metastases at initial diagnosis. In mouse xenograft models, NF1-depleted ER+ breast cancer cells demonstrated enhanced dissemination to skeletal sites following surgical resection of primary tumors. …

Inaccurate Interpretation Of Hypoxia Signatures From Transcriptomic Analyses In Neuro-Oncology, Rebecca K Simmons, Pratima Raut, Subhi Talal Younes, Marco Gallo

Faculty, Staff and Students Publications

We aim to highlight problems with the biological interpretation of computationally-derived hypoxia signatures for neuro-oncology research. By reviewing important experimental work in the field, we discuss common misinterpretations of the concepts of normoxia and hypoxia. In fact, the concentration of oxygen in the adult brain is in the range of 1-7%. Unfortunately, this oxygen concentration range is often mistakenly considered hypoxic in neuro-oncology experiments, although it should be considered physioxic. Further, given the lack of a universal hypoxic signature, we stress the importance of deriving cell type-specific hypoxic signatures using carefully-executed experiments.

INTRODUCTION: Patient and arteriovenous malformation (AVM) characteristics that portend success after treatment for low-grade brain AVMs remain unknown.

PATIENTS AND METHODS: We utilised the MISTA multicentre registry to identify patients with Spetzler-Martin (SM) grade I or II AVMs treated with stand-alone curative-intent intervention (resection, stereotactic radiosurgery [SRS] or endovascular embolisation). Bivariate and multivariable analyses were performed to identify patient and AVM characteristics predictive of complete obliteration or favourable outcome (complete obliteration without new permanent deficit or post-treatment haemorrhage).

RESULTS: A total of 522 patients were included (292 microsurgery, 152 SRS, 78 embolisation). Complete obliteration rates differed between microsurgery (95.9%), SRS …

Faculty, Staff and Students Publications

The majority of breast cancer patients have tumors expressing estrogen receptor α (ER) and receive endocrine therapy. However, around one-third relapse in their disease, predominantly with retained ER expression. Molecular alterations are proposed to be contributors to the resistance mechanisms. Patients with ER-positive, human epidermal growth factor receptor 2 (HER2)-negative primary breast cancer with an ER-positive relapse <  5 years of ongoing endocrine therapy were retrospectively assessed. Extracted DNA was analyzed through panel sequencing, and RNA by microarray, from patients’ primary (n = 58), and paired relapse tumors (n = 54), and tumor-free lymph nodes (DNA germline controls, n = 62). Several single-nucleotide variations and copy number variations showed nominal exploratory associations with worse overall survival. Copy number correlations with intrinsic subtypes and …

Retrieval Strategies For Embolized Left Atrial Appendage Closure Devices, Usama Sadiq, Muneeba Ali, Stacey Damito, Maxwell Ambrosino, Muhammad Sabri, Muhammad Ahmad Sadiq, Muhammad Hamza Sadiq, Richard Kovach, Sheena Rastogi, Muhammad Raza

Abington Jefferson Health Papers

BACKGROUND: Device embolization (DE) is a rare but potentially life-threatening complication of left atrial appendage occlusion (LAAO). As landmark trials broaden the eligible population for LAAO, operator preparedness for DE management becomes increasingly critical.

CASE SUMMARY: We present 4 cases of LAAO DE managed with distinct retrieval strategies: 1) open surgical retrieval with concurrent AtriClip ligation for an endothelialized left atrial device; 2) sequential transseptal then retrograde arterial snaring for intraprocedural migration to the abdominal aorta; 3) transseptal retrieval using a dedicated ONO system with cerebral embolic protection for partial left atrial dislodgment; and 4) retrograde large-bore arterial retrieval for …

Endothelin Receptor Antagonists In Resistant Hypertension And Proteinuric Kidney Disease: Receptor Strategy And Volume Management, Corey Keith Goldman, Jesse M. Goldman

Division of Nephrology Faculty Papers

This narrative review examines how endothelin receptor antagonists (ERAs) can be used at the intersection of difficult-to-control hypertension, chronic kidney disease (CKD), and albuminuria or proteinuria. For clinicians, the central question is not receptor selectivity alone, but whether a specific agent, indication, dose, background therapy, and monitoring plan can deliver meaningful blood-pressure or kidney benefit without unacceptable fluid retention. Pulmonary arterial hypertension established the pharmacology and major safety liabilities of the class; the current implementation questions for hypertension and kidney specialists arise in systemic hypertension and proteinuric kidney disease. Aprocitentan is the first and only ERA approved for hypertension; in …

Longevity and stress resilience require precise coordination of gene expression programs across tissues. Here, we demonstrate that overexpression of the chromatin reader bet-1 specifically in neurons of Caenorhabditis elegans promotes organismal longevity and stress resistance via cell-nonautonomous signaling. Neuronal bet-1 elicits a neurotransmitter-dependent signal that activates the conserved stress-responsive transcription factor HSF-1 in the intestine, enhancing proteostasis, oxidative stress resistance, metabolic remodeling, and immune defense. Life span extension by neuronal bet-1 requires both hsf-1 and daf-16 in neurons but only requires hsf-1 in peripheral tissues. Using bulk RNA sequencing, we reveal distinct prolongevity pathways that include enhanced heat-shock response, proteostasis, …

Department of Neurosurgery Faculty Papers

BACKGROUND: Symptom evolution in degenerative cervical myelopathy (DCM) is traditionally characterized by severity of neurological deficit. A recent expert consensus challenged this view, proposing that DCM fluctuates across neurological, functional and health-related quality of life measures. We examined whether joint changes across these three domains define distinct recovery patterns in a clinic-based cohort of adult patients with DCM.

METHODS: Cohorts analysed were the Cervical Spondylotic Myelopathy-North America (CSM-NA, 2005-2007, N = 278), CSM-International (CSM-I, 2007-2011, N = 479) and the CSM-PROTECT Trial (2012-2017, N = 290). All participants were symptomatic adult DCM patients who underwent surgical treatment and completed at …

An Investigation Of Pelvic Kinematics And Implications For Total Hip Arthroplasty, Kathryn Holland Colone

Electronic Theses and Dissertations

Total hip arthroplasty (THA) is one of the most commonly performed orthopaedic procedures, with approximately 500,000 surgeries performed annually in the United States alone. Although THA is widely regarded as highly successful, postoperative complications persist, highlighting the multifactorial nature of THA outcomes. Previous studies have demonstrated the importance of implant positioning and soft tissue mechanics, yet challenges remain in optimizing surgical decisions on a patient-specific basis. Recent advances in surgical planning tools have shifted the focus of preoperative planning toward optimizing patient-specific outcomes, highlighting the need to better understand how patient anatomy, surgical technique, and joint mechanics interact to influence …

Department of Neurosurgery Faculty Papers

Central cord syndrome (CCS) is the most common form of incomplete cervical spinal cord injury (SCI), yet its optimal management remains controversial. We examined whether stratifying CCS by injury stability improves treatment assessment. CCS was defined as an American Spinal Injury Association Impairment Scale (AIS) C/D cervical SCI with a ≥5-point lower-upper extremity motor score difference and classified as CCS-stable (CCS-S) or -unstable (CCS-U) based on the absence or presence of fracture/dislocation. Functional recovery at 1 year was assessed using the functional independence measure (FIM) motor score. Among 291 patients, 131 (45%) had CCS-S. These patients were older and more …

Purpose: SMARCB1-deficient renal medullary carcinoma (RMC) is an ultra-rare, lethal malignancy refractory to therapies approved for other renal cell carcinomas, and its rarity makes randomized trials logistically unfeasible. We investigated whether wild-type epidermal growth factor receptor (EGFR) is a therapeutically actionable dependency in RMC and translated this insight into a deployable clinical regimen.

Experimental design: EGFR expression was assessed by CLIA-certified immunohistochemistry in RMC tumors and by integrated RNA- and chromatin immunoprecipitation-sequencing of primary tumors and adjacent kidney. Panitumumab was compared with erlotinib in patient- and cell line-derived xenografts, and its mechanism defined by immunoblotting, confocal colocalization, cell-cycle and apoptosis …

Countering Hpv Vaccine Misinformation On Social Media: Practical Strategies For Healthcare Providers, David Baldwin

Lynchburg Journal of Medical Science

Human papillomavirus (HPV) vaccination is a highly effective strategy for preventing cervical and other HPV-related cancers; however, vaccine hesitancy remains a significant barrier to optimal vaccination rates. Social media has become a major source of health information while simultaneously amplifying misinformation that influences parental attitudes toward HPV vaccination. This narrative literature review examined the relationship between social media misinformation and HPV vaccine hesitancy and identified evidence-based strategies healthcare providers can use to improve vaccine confidence.

A literature search of PubMed and Google Scholar identified 31 articles published between 2016 and 2025, of which 19 met inclusion criteria. The literature demonstrates …

Should H2-Blockers Be Used For The Treatment Of Laryngopharyngeal Reflux?, Sophia Linguiti, W. Jack Palmer, Janvi J. Shukla, Kathleen Tibbetts, Colin Huntley, Joseph Spiegel

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

Laryngopharyngeal reflux (LPR) is a highly prevalent condition in otolaryngology practice, characterized by reflux of gastric contents into the pharynx and larynx. Although proton pump inhibitors (PPIs) remain first-line therapy, many patients report persistent symptoms. In refractory cases, histamine-2 receptor antagonists (H2RAs) are often employed as adjunctive or standalone therapy due to their rapid onset and accessibility. However, their utility as daily therapy is limited by tachyphylaxis, with significant loss of acid suppression within days of continuous use. Despite longstanding evidence from gastroenterology literature discouraging daily H2RA therapy, these agents remain frequently prescribed in otolaryngology practice. Contemporary ear, nose, and …

BACKGROUND: Adalimumab is widely used for hidradenitis suppurativa (HS), but treatment durability varies and predictors of sustained benefit remain uncertain.

OBJECTIVE: To identify clinical and laboratory factors associated with adalimumab treatment durability in HS.

METHODS: We retrospectively studied 135 adults with HS who initiated adalimumab as first biologic therapy across three academic centers from 2013 to 2023. Outcomes were categorized as primary failure (12-24 weeks), secondary failure (24 weeks-2 years), or sustained response (>2 years) based on discontinuation for inefficacy. Predictors of treatment durability were evaluated using ordinal logistic regression.

RESULTS: In univariable analyses, Hurley stage 3, higher body …

Cells And Networks In Flux: Rethinking Ontogenesis And Pathogenesis, Mark L. Tykocinski

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Organ and tissue functions emerge from the coordinated activity of cell networks. Therapeutics that act on pathogenic cell networks, modulating their cellular interplay, follow naturally. Over several decades, our laboratory has developed a series of approaches for rewiring cell networks, culminating in a class of cell surface-directed signal converter proteins (SCPs) that do so by modulating juxtacrine and autocrine signaling in and among their nodal cells. A first such SCP has now produced encouraging clinical data for cancer immunotherapy. Yet, these early network-directed fusion proteins rest on a deliberately simplified picture: discrete end-cell types plugged into graphically tractable networks. That …

Nascent Adam17 Synthesis Potentiates Gpibα Cleavage In Resting And Stimulated Stored Platelets, Shayan Askari, Harriet Ghansah, Christopher D. Mansi, Timothy J. Stalker, Lawrence E. Goldfinger

Cardeza Foundation for Hematologic Research

Platelet concentrates stored at room temperature have a shelf life of 5 to 7 days. During storage, platelets undergo glycoprotein cleavage by metalloproteases, notably cleavage of glycoprotein Ibα (GPIbα) by a disintegrin and metalloprotease 17 (ADAM17), which leads to decreased posttransfusion reactivity and recovery. To investigate the putative roles of nascent synthesis of ADAM17 in GPIbα shedding and platelet function during room temperature platelet storage. Human platelets maintained in autologous plasma were treated with naked endonuclease-resistant ADAM17 or control short inhibitory RNA (siRNA) and monitored for molecular and cellular effects during storage. Platelet-specific Adam17-deleted mice were generated, and the dynamics …

Selective Loss Of Primary Cilia And Neurotrophic Signaling In G51d Α-Synuclein Mice Highlights A Common Pathway To Parkinson’S Disease, Yu-En Lin, Ebsy Jaimon, Youngdoo Kim, Annabeth Loftman, Aaran Vijayakumaran, Benjamin D W Belfort, Claire Y Chiang, Benjamin R Arenkiel, Huda Y Zoghbi, Suzanne R Pfeffer

Duncan NRI Faculty and Staff Publications

Parkinson's disease is characterized by dopaminergic neuron loss and accumulation of α-synuclein aggregates in the brain. G51D α-synuclein knock-in mice provide a genetically and clinically relevant model of disease, exhibiting early olfactory deficits, age-dependent motor impairment, and progressive phospho-α-synuclein accumulation. In multiple Parkinson's disease models, striatal cholinergic and parvalbumin interneurons, as well as astrocytes, lose primary cilia and the neurotrophic signaling needed to sustain dopaminergic neurons. We show here that G51D α-synuclein mice share these phenotypes. Phospho-Ser129 α-synuclein accumulation correlates with cilia loss in cholinergic interneurons but not in spiny projection neurons that accumulate higher phospho-α-synuclein levels. In the piriform …
