Oncogenic MYCN drives aggressive disease in many cancers including neuroblastoma (NB). Metabolic reprogramming is essential to support cancer cell homeostasis and survival under nutrient- and oxygen-deprived conditions. MYCN directly reprograms many nodes of tumor-intrinsic metabolism, which have significant repercussions on the cells of the tumor microenvironment (TME), resulting in complex intercellular metabolic circuits that contribute to the immunosuppressive microenvironment of NB. These metabolic circuits are also regulated by the organismal and cellular circadian clock and host diet to further impact the TME and NB oncogenesis. This review discusses the mechanisms by which MYCN regulates the metabolic crosstalk between tumor, TME, …

The Hippo pathway controls organ development, homeostasis, and regeneration primarily by modulating YAP/TEAD-mediated gene expression. Although emerging studies report Hippo-YAP dysfunction after viral infection, it is largely unknown in the context of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Here, we analyzed RNA sequencing data from human-induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) and SARS-CoV-2-infected human lung samples, and observed a decrease in YAP target gene expression. In screening SARS-CoV-2 nonstructural proteins, we found that nonstructural protein 13 (NSP13), a conserved coronavirus helicase, inhibits YAP transcriptional activity independent of the upstream Hippo kinases LATS1/2. Consistently, introducing NSP13 into mouse cardiomyocytes suppresses …

Adenylosuccinate lyase deficiency (ADSLd) is a rare autosomal recessive purine metabolism disorder with several clinical manifestations. While toxic substrate accumulation is a known hallmark, no additional molecular mechanisms have been established. Here, we show that ADSLd is associated with mitochondrial dysfunction, including increased fragmentation, impaired respiration, and reduced ATP production. The severity of mitochondrial impairment correlates with ADSLd pathology, especially in mitochondria-dependent tissues. We also identify defects in mitochondrial dynamics and transport linked to ERK2 and AKT suppression. Notably, overexpressing constitutively active ERK2 or supplementing purine intermediates partially rescues the mitochondrial phenotype. These findings suggest an alternative disease mechanism and …

TDP43 is an RNA/DNA-binding protein increasingly recognized for its role in neurodegenerative conditions, including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). As characterized by its aberrant nuclear export and cytoplasmic aggregation, TDP43 proteinopathy is a hallmark feature in over 95% of ALS/FTD cases, leading to detrimental cytosolic aggregates and a reduction in nuclear functionality in neurons. Building on our prior work linking TDP43 proteinopathy to the accumulation of DNA double-strand breaks (DSBs) in neurons, the present investigation uncovers a novel regulatory relationship between TDP43 and DNA mismatch repair (MMR) gene expression. Here, we show that TDP43 depletion or overexpression …

- Flexible nasopharyngolaryngoscopy (NPL) is a core diagnostic and procedural skill in otolaryngology, radiation oncology, and related specialties. Early mastery is essential for safe patient care, but traditional training is limited by:

  • Reliance on patient encounters, which may cause discomfort and restrict practice opportunities.
  • High cost of commercial simulators(often $3,000–$5,000), restricting access across many programs.
  • Lack of anatomical accuracyin available models, limiting their educational value.

- Gap: There is currently no accessible, anatomically faithful, and affordable tool for widespread trainee use.

- Objective: To design, fabricate, and validate a low-cost, anatomically accurate 3D-printed simulator for training in flexible NPL


Retracted: Idea Density And Grammatical Complexity As Neurocognitive Markers, Diego Iacono, Gloria Feltis Sep 2025

Retracted: Idea Density And Grammatical Complexity As Neurocognitive Markers, Diego Iacono, Gloria Feltis

Department of Neurology Faculty Papers

Language, a uniquely human cognitive faculty, is fundamentally characterized by its capacity for complex thoughts and structured expressions. This review examines two critical measures of linguistic performance: idea density (ID) and grammatical complexity (GC). ID quantifies the richness of information conveyed per unit of language, reflecting semantic efficiency and conceptual processing. GC, conversely, measures the structural sophistication of syntax, indicative of hierarchical organization and rule-based operations. We explore the neurobiological underpinnings of these measures, identifying key brain regions and white matter pathways involved in their generation and comprehension. This includes linking ID to a distributed network of semantic hubs, like …

Humans with pathogenic variants of the manganese (Mn) transporter gene SLC39A14 exhibit highly elevated brain Mn concentrations and childhood-onset dystonia-parkinsonism. Here we show that Slc39a14-knockout (KO) mice, a preclinical model of the disease with elevated Mn concentrations in the CB, express deficits in physiological tremor implicating cerebellar (CB) dysfunction. Imaging of intracellular Mn in Purkinje cells (PCs) using synchrotron-based X-ray fluorescence microscopy confirmed highly elevated Mn concentrations in the PCs of Slc39a14-KO mice. To determine biological pathways altered in the CB of Slc39a14-KO mice relative to wildtype (WT), we performed RNA sequencing and discovered significant upregulation of pathways and genes …

The micromorphology of composite cathodes is known to play a vital role in determining all‐solid‐state battery (ASSB) performance. However, much of our current understanding is derived from empirical observations, lacking a deeper mechanistic foundation. The “rocking chair” concept of battery chemistry requires maintaining charge neutrality, emphasizing the necessity of examining electrode micromorphology from the perspective of conductive networks. This study systematically investigates the microscopic electrochemical impacts of conductive network micromorphology by varying the Li+‐to‐e− channel ratio in cathodes comprising LiNbO3‐coated LiNi0.8Co0.1Mn0.1O2, Li6PS5Cl, and carbon fibers. Utilizing multiscale synchrotron‐based spectro‐microscopy, we unravel that unbalanced Li+ and e− conducting channels intensify charge …

Research Colloquium

Background: Alzheimer’s disease (AD) is the most common form of dementia and one of the leading causes of disability and death in the United States1. Research efforts aim to identify pathological changes that may help support earlier detection of AD and lead to more accessible tools for monitoring disease progression2. The retina is being explored as a potential non-invasive marker of AD, reflecting the shared embryology and microvasculature features between the retina and the brain. Although research has focused on structural changes in retinal vessel diameters and density, few studies have evaluated functional markers of retinal …

Improving Outcomes In Pediatric Congenital Heart Disease: The Integration Of Wearable Technology And Ai-Driven Analysis, Sophia Moon, Melissa Cruz, Pad Renga

Research Colloquium

Background: Wearable devices such as biosensors and smartwatches have demonstrated clinical utility in arrhythmia detection in adult populations, but their integration into pediatric congenital heart disease (CHD) care remains limited. Despite advances in CHD management, challenges persist in the timely identification of arrhythmias in children. The use of wearables in pediatrics is constrained by research gaps, adherence issues, and complex data interpretation. Traditional tools like Holter monitors and event recorders face limitations in detecting intermittent arrhythmias and ensuring compliance. These devices cannot leverage artificial intelligence (AI) and machine learning (ML) to enhance ECG interpretation. This study analysis evaluates the potential …


Geriatric Brittle Type 1 Diabetes Mellitus: Case Study And Management Strategies, Saba Irfan, Amanda Cantu Sep 2025

Geriatric Brittle Type 1 Diabetes Mellitus: Case Study And Management Strategies, Saba Irfan, Amanda Cantu

Research Colloquium

“Brittle diabetes” describes a form of diabetes marked by severe, unpredictable fluctuations in blood glucose, often leading to frequent episodes of hypoglycemia and hyperglycemia. Though not formally recognized by major diabetes organizations, the term is clinically useful, especially for vulnerable populations such as older adults with Type 1 Diabetes Mellitus (T1DM). Age-related factors—cognitive impairment, mobility limitations, dexterity issues, sensory decline, inconsistent eating habits, and frailty—make glycemic control particularly challenging and require a personalized, multidisciplinary management approach.

We report the case of a 66-year-old Hispanic female with long-standing T1DM, seizure disorder, and osteoporosis. Despite adherence to a prescribed insulin regimen, her …


Implementing A Specific And Standardized Grading Scale For Therapeutic Injection Site Reactions To Improve Adverse Event Reporting, Priya Kale, Kavita Sarin Sep 2025

Implementing A Specific And Standardized Grading Scale For Therapeutic Injection Site Reactions To Improve Adverse Event Reporting, Priya Kale, Kavita Sarin

Research Colloquium

Up to 15.5% of patients taking biologic medication experience injection site reactions (ISRs) leading to morbidity, early discontinuation, and reduced treatment compliance. As biologic medications are increasingly used to treat chronic inflammatory conditions, including psoriasis and atopic dermatitis, there needs to be an improved understanding of ISRs. However, current methods of grading ISRs are nonspecific and unstandardized leading to a lack of understanding of medication-specific ISRs and ambiguity in perceptions of treatment tolerability. Here we aim to develop a standardized ISR grading scale for use in clinical trials. A scoping review was performed to evaluate current ISR grading scales and …
