Glioblastoma (GBM) remains difficult to treat due to poor drug delivery across the blood-brain barrier and an immunosuppressive tumor microenvironment (TME). Tumor-suppressive microRNAs (miRNAs) offer a promising strategy to reprogram both tumor cells and the TME, but inefficient delivery systems limit their clinical application. We previously reported that tumor-suppressive miR-138 regresses tumor growth in preclinical GBM models. Here, we demonstrate that trypsin digestion of extracellular vesicles (EVs) enhances labeling efficiency with folate (FA), enhancing selective targeting of folate receptor (FR)-positive GBM cells and enabling simultaneous targeting of tumor-associated macrophages (TAMs). FA-labeled trypsinized EVs (tEVs) loaded with miR-138 inhibit tumor growth, …

Bone metastasis is a major cause of cancer death; however, the epigenetic determinants driving this process remain elusive. Here, we report that histone methyltransferase ASH1L is genetically amplified and is required for bone metastasis in men with prostate cancer. ASH1L rewires histone methylations and cooperates with HIF-1α to induce pro-metastatic transcriptome in invading cancer cells, resulting in monocyte differentiation into lipid-associated macrophage (LA-TAM) and enhancing their pro-tumoral phenotype in the metastatic bone niche. We identified IGF-2 as a direct target of ASH1L/HIF-1α and mediates LA-TAMs' differentiation and phenotypic changes by reprogramming oxidative phosphorylation. Pharmacologic inhibition of the ASH1L-HIF-1α-macrophages axis elicits …

Acute myeloid leukemia (AML) resides in an immune-rich microenvironment, yet, immune-based therapies have faltered in eliciting durable responses. Bridging this paradox requires a comprehensive understanding of leukemic interactions within the bone marrow microenvironment. We optimized a high-throughput tissue-microarray-based pipeline for high-plex spatial immunofluorescence and mass cytometry imaging on a single slide, capturing immune, tumor, and structural components. Using unbiased clustering on the spatial K function, we unveiled the presence of tertiary lymphoid-like aggregates in bone marrow, which we validated using spatial transcriptomics and an independent proteomics approach. We then found validated TLS signatures predictive of outcomes in AML using an …

With age, hematopoietic stem cells can acquire somatic mutations in leukemogenic genes that confer a proliferative advantage in a phenomenon termed CHIP. How these mutations result in increased risk for numerous age-related diseases remains poorly understood. We conduct a multiracial meta-analysis of EWAS of CHIP in the Framingham Heart Study, Jackson Heart Study, Cardiovascular Health Study, and Atherosclerosis Risk in Communities cohorts (N = 8196) to elucidate the molecular mechanisms underlying CHIP and illuminate how these changes influence cardiovascular disease risk. We functionally validate the EWAS findings using human hematopoietic stem cell models of CHIP. We then use expression quantitative …

Faculty, Staff and Student Publications

Background: Dietary guidelines recommend adequate protein intake from diverse sources for optimal blood pressure; however, its role in hypertension risk remains unclear. We examined prospective associations of protein intake and diversity, overall and by source, with hypertension risk in the MESA (Multi-Ethnic Study of Atherosclerosis) study.

Methods and results: Among 2294 participants aged 45 to 84 years without hypertension at baseline, total, animal, and plant protein intake was assessed using a 120-item food frequency questionnaire. Protein diversity was evaluated using count and the dissimilarity index. Over a 9-year median follow-up, 1356 hypertension cases were identified through blood pressure measurements and …

A Fundamentally New Direction In Embolization Using Reactive Chemistry In A Swine Model, Erik Cressman, Danielle Stolley, Shubhneet Warar, Natalie W Fowlkes, David Fuentes

Faculty, Staff and Student Publications

Liver cancer carries a poor prognosis and incidence continues to increase. The main therapy for unresectable disease > 3 cm in diameter is Transarterial Chemoembolization. Unfortunately, overall survival for these patients has improved little in the past two decades. To address this, we propose a new approach using a chemical reaction in situ. We report here our results in a pilot study using a swine model. Domestic swine (n = 3) were treated in the liver with dichloroacetic anhydride in ethiodized oil. CT imaging was followed 24 h after the procedure by necropsy, histopathology, and mass spectrometry imaging. Animals tolerated the …

Faculty, Staff and Student Publications

Background: Genetic ancestry is an important factor to account for in DNA methylation studies because genetic variation influences DNA methylation patterns. One approach uses principal components (PCs) calculated from CpG sites that overlap with common SNPs to adjust for ancestry when genotyping data is not available. However, this method does not remove technical and biological variations, such as sex and age, prior to calculating the PCs. The first PC is therefore often associated with factors other than ancestry.

Methods: We developed and adapted the adapted EpiAnceR + approach, which includes 1) residualizing the CpG data overlapping with common SNPs for …

Detailed social determinants of health (SDoH) is often buried within clinical text in EHRs. Most current NLP efforts for SDoH have limitations, investigating limited factors, deriving data from a single institution, using specific patient cohorts/note types, with reduced focus on generalizability. We aim to address these issues by creating cross-institutional corpora and developing and evaluating the generalizability of classification models, including large language models (LLMs), for detecting SDoH factors using data from four institutions. Clinical notes were annotated with 21 SDoH factors at two levels: level 1 (SDoH factors only) and level 2 (SDoH factors and associated values). Compared to …

Although pathological complete response (pCR) and major pathological response (MPR) rates of neoadjuvant immunotherapy combined with chemotherapy in head and neck squamous cell carcinoma (HNSCC) trials remain suboptimal, emerging evidence highlights the synergistic potential of combining low-dose radiotherapy with immunotherapy to promote the efficacy of immunotherapy. This phase II, open-label, single-arm, multicenter trial (NCT05343325) enrolled 28 patients with untreated stage III-IVB HNSCC (NeoRTPC02). Patients received neoadjuvant low-dose radiotherapy, the programmed death-1 (PD-1) inhibitor tislelizumab, albumin-bound paclitaxel, and cisplatin for two cycles, followed by radical resection ~4 weeks after treatment completion. The primary endpoint, pCR rate, was achieved in 14 of …

Are We Ready For Ai-Augmented Generalists?, Jiajie Zhang

Faculty, Staff and Student Publications

Artificial Intelligence (AI) is reshaping medical practice and education by unifying the knowledge of medical specialties and subspecialties into a single, intelligent system. This system functions not only as an integrated knowledge base but also as an active cognitive collaborator. By bridging knowledge gaps beyond the capacity of any individual clinician, AI could enable physicians to function as AI-augmented generalists who can perform certain tasks that require specialist training. These generalists may help mitigate care fragmentation, but realizing their potential will require significant changes in medical education.

Background/Objectives: We aimed to discover genes with bimodal expression linked to patient outcomes, to reveal underlying oncogenotypes and identify new therapeutic insights in lung adenocarcinoma (LUAD).

Methods: We performed meta-analysis to screen LUAD datasets for prognostic genes with bimodal expression patterns. Kynureninase (KYNU), a key enzyme in tryptophan catabolism, emerged as a top candidate. We then examined its relationship with LUAD mutations, metabolic alterations, immune microenvironment states, and expression patterns in human and mouse models using bulk and single-cell transcriptomics, metabolomics, and preclinical model datasets. Pan-cancer prognostic associations were also assessed.

Results: Model-based clustering of KYNU expression outperformed median-based dichotomization …

Altered protein homeostasis through proteasomal degradation of ubiquitinated proteins is a hallmark of many cancers. Ubiquitination, coordinated by E1, E2, and E3 enzymes, involves up to 40 E2-conjugating enzymes in humans to specify substrates and ubiquitin linkages. In a screen for E2 dependencies in acute myeloid leukemia (AML), ubiquitin conjugating enzyme E2 N (UBE2N) emerged as the top candidate. To investigate UBE2N's role in AML, we characterized an enzymatically defective mouse model of UBE2N, revealing UBE2N's requirement in AML without an impact on normal hematopoiesis. Unlike other E2s, which mediate lysine-48 (K48) polyubiquitination and degradation of proteins, UBE2N primarily synthesizes …

Meticulous curation and collaboration with data depositors produced a robust and comprehensive database, …

G-Quadruplex Stabilizer Cx-5461 Effectively Combines With Radiotherapy To Target Α-Thalassemia/Mental Retardation X-Linked-Deficient Malignant Glioma, Sharvari Dharmaiah, Prit Benny Malgulwar, William E Johnson, Brandon A Chen, Vladislav Sharin, Benjamin T Whitfield, Christian Alvarez, Vasudev Tadimeti, Ahsan S Farooqi, Jason T Huse

Faculty, Staff and Student Publications

Background: Inactivation of α-thalassemia/mental retardation X-linked (ATRX) represents a defining molecular feature in large subsets of malignant glioma. ATRX deficiency gives rise to abnormal G-quadruplex (G4) DNA secondary structures, enhancing replication stress and genomic instability. Building on earlier work, we evaluated the extent to which pharmacological G4 stabilization selectively enhances DNA damage and cell death in ATRX-deficient preclinical glioma models.

Methods: Using the G4 stabilizer CX-5461, we treated patient-derived glioma stem cells (GSCs) in vitro and GSC flank and intracranial murine xenografts in vivo to evaluate efficacy as both a single agent and in combination with ionizing radiation (IR), the …

Neoadjuvant immunotherapy can induce pathologic complete response (pCR) in patients with localized deficient mismatch repair (dMMR)/microsatellite instability-high (MSI-H) tumors. The long-term outcomes of these patients are unknown, as is the clinical utility of measuring circulating tumor DNA (ctDNA). Follow-up was evaluated in patients enrolled in a phase II trial (NCT04082572) that evaluated the efficacy and safety of pembrolizumab in patients with localized dMMR/MSI-H tumors. The primary outcomes of this trial have previously been reported. 3-year EFS and OS rates were 80% (95% CI: 66% - 93%) and 94% (95% CI: 86% - 100%). Patients without detectable ctDNA after pembrolizumab had …

Influenza-associated pulmonary aspergillosis (IAPA) is a potentially deadly superinfection in patients with influenza pneumonia, especially those with severe disease, underlying immunosuppression, corticosteroid therapy, or requiring intensive care support. Given the high mortality of IAPA, adjunct immunomodulatory strategies remain a critical unmet need. Previously, the desensitization of pattern recognition pathways has been described as a hallmark of IAPA pathogenesis and a predictor of mortality in IAPA patients. Therefore, we studied the impact of nebulized Toll-like receptor 2/6/9 agonists Pam2 CSK4 (Pam2) and CpG oligodeoxynucleotides (ODNs) on infection outcomes and pulmonary immunopathology in a corticosteroid-immunosuppressed murine IAPA model. Mice with IAPA receiving …

Candida is one of the most frequent causes of bloodstream infections, and our first line of defense against these invasive infections is the innate immune system. The early immune response is critical in controlling Candida albicans infection, but C. albicans has several strategies to evade host immune attack. Phagocytosis of C. albicans blocks hyphal growth, limiting host damage and virulence, but how C. albicans limits early recruitment and phagocytosis in vertebrate infection is poorly understood. To study innate immune evasion by intravital imaging, we utilized the transparent larval zebrafish infection model to screen 131 C. albicans mutants for altered …

Faculty, Staff and Student Publications

Malignant tumors represent a significant threat to human health. Among the various therapeutic strategies available, cancer immunotherapy-encompassing adoptive cell transfer (ACT) and immune checkpoint blockade therapy-has emerged as a particularly promising approach following surgical resection, radiotherapy, chemotherapy, and molecular targeted therapies. This form of treatment elicits substantial antigen-specific immune responses, enhances or restores anti-tumor immunity, thereby facilitating the control and destruction of tumor cells, and yielding durable responses across a range of cancers, which can lead to the eradication of tumor lesions and the prevention of recurrence. Tumor-infiltrating lymphocytes (TILs), a subset of ACT, are characterized by their heterogeneity and …
