Department of Medicine Faculty Papers

OBJECTIVES: There is debate regarding the optimal choice for a second conduit in coronary artery bypass grafting. The right internal mammary artery (RIMA) is commonly employed as a second conduit; however, it is unclear whether the free (fRIMA) or in situ (isRIMA) configuration yields superior outcomes. We performed a systematic review and meta-analysis to compare clinical outcomes between fRIMA and isRIMA as the second conduit.

METHODS: A comprehensive search of PubMed (MEDLINE), EMBASE, and CENTRAL was performed through May 2025 to identify studies comparing outcomes in patients undergoing coronary artery bypass grafting with either fRIMA or isRIMA as a second …

Breast Cancer-Derived Extracellular Vesicle Mir-425-5p (Mir-425) Promotes Brain Metastasis Via Activating Astrocytes Through The Novel Mir-425-Znf24-Ccl8 Signaling Axis, Grace L Wong, Munazza S Khan, Sara Manore, Shivani Bindal, Ravi Singh, Hui-Wen Lo

Faculty, Staff and Student Publications

Mechanisms underlying breast cancer brain metastasis (BCBM) are still not well understood. Here, we identified that BCBM patient serum contained extracellular vesicles (EVs) with high levels of microRNAs (miRNAs)-107 and -425. Levels of miR-107 and miR-425 were elevated in brain metastases, and the elevation was associated with poor patient prognoses. Ectopic expression of miR-107 and miR-425 promoted mammospheres; however, the inhibition of miR-425, but not miR-107, suppressed breast cancer mammosphere formation. We further observed that EVs from miR-425-overexpressing breast cancer cells strongly activated astrocytes whereas their inhibitors abrogated the effect. Conditioned media from miR-425-activated astrocytes promoted mammospheres. To elucidate how …

Wills Eye Hospital Papers

Background/Objectives: Inherited retinal diseases (IRDs) represent a genetically heterogeneous group of disorders caused by mutations in over 280 genes with more than 3100 identified variants. While gene-specific replacement therapies have achieved landmark success with voretigene neparvovec (Luxturna) for biallelic RPE65-associated retinal dystrophy, developing individual therapies for each genetic subtype remains impractical. This review examines gene-agnostic therapeutic approaches utilizing neuroprotection and immunomodulation that target common pathophysiological mechanisms shared across multiple IRD genotypes. Methods: We reviewed the literature on neuroprotective and immunomodulatory gene therapy strategies for IRDs, focusing on neurotrophic factors and complement system modulation. Results: Neuroprotective approaches delivering neurotrophic factors—including pigment …

Ribosomal Stress In The Pathogenesis And Treatment Of T-Cell Acute Lymphoblastic Leukemia, Kimberly Bridget Johansson

Arts & Sciences Graduate Student Theses and Dissertations

T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematologic malignancy in which activating mutations in the Notch pathway are thought to contribute to transformation, in part, through activation of c-Myc. Increased expression of c-Myc induces oncogenic stress that can lead to apoptosis through the Mdm2-p53 tumor suppressor pathway. Since the great majority of T-ALL cases maintain wildtype MDM2 and TP53, we hypothesized that T-ALL cells are selectively sensitive to MDM2 inhibition. Treatment with idasanutlin, an MDM2 inhibitor, although only inducing modest apoptosis in T-ALL cells, resulted in a significant upregulation of pro-apoptotic BH3 domain genes BAX and BBC3. This prompted …

Measurable Residual Disease Testing In Acute Myeloid Leukemia: Current State, Foundational Models, And Tools For Future Development, Joseph Van Galen, Stephen D. Willis, Ashish Bains, Sara H. Small

Department of Medical Oncology Faculty Papers

Acute myeloid leukemia (AML) is a lethal and rapidly progressive hematologic malignancy with high rates of relapse and treatment refractoriness. Management of AML is complicated by biological heterogeneity in a disease that is broadly defined by the clonal expansion of myeloblasts that otherwise play an important role in healthy marrow tissues. While subtypes of AML are increasingly defined by druggable driver mutations including FLT3-ITD, IDH1, IDH2, and NPM1, conventional chemotherapy and reduced intensity induction regimens (e.g., azacitidine-venetoclax) remain therapeutic backbones. One area of active development for personalization of AML treatment is the assessment of measurable residual disease (MRD). MRD testing …

Donor Sex And Platelet Storage Change The Therapeutic Effects Of Platelet-Derived Extracellular Vesicles On Endothelium, Mandeep Kaur, Malvika Gupta, Sowmya Shree Gopal, Charles E. Wade, Jessica C. Cardenas, Amit K. Srivastava

Cardeza Foundation for Hematologic Research

Platelet-derived extracellular vesicles (PEVs) play an active role in vascular protection and repair and are being explored as a viable alternative to platelet therapy. Because platelet function and stability are shaped by donor sex and storage conditions, these same factors are likely to influence the PEVs they release. Understanding these influences is key to developing PEVs into a safe and dependable therapeutic option. In this study, we investigated how donor sex and platelet storage affect the therapeutic properties of PEVs. To address this, PEVs were isolated from platelets of healthy male and female donors. Platelets were either processed immediately after …

Real-world inpatient practice patterns remain incompletely described in contemporary U.S. data. Our aim was to evaluate national inpatient practice patterns, predictors of procedural intervention, and associated in-hospital outcomes and resource utilization among patients hospitalized with lung abscess managed conservatively, with bronchoscopic drainage, or with percutaneous drainage.

Methods: Using the National Inpatient Sample (NIS) (2016–2018), we identified adult (18 years and older) hospitalizations with a principal diagnosis of lung abscess [International Classification of Diseases, 10th …

Cbx6-Ca9 Axis: An Epigenetic-Metabolic Vulnerability In Glioblastoma, Keykavous Parang

Pharmacy Faculty Articles and Research

Glioblastoma (GBM) remains one of the most therapeutically recalcitrant malignancies, with median survival rarely exceeding 15 months despite maximal therapy.¹ The hypoxic tumor microenvironment drives treatment resistance through epigenetic and metabolic adaptations.²

In this issue of Molecular Therapy Oncology, the study by Wang et al.³ demonstrates a novel regulatory axis between CBX6 (chromobox 6), a polycomb group protein, and CA9 (carbonic anhydrase 9), revealing how hypoxia-driven epigenetic reprogramming promotes tumor progression and identifying a mechanistically linked pathway for therapeutic intervention in GBM.

The study by Wang et al.3 advances our understanding of how the tumor microenvironment …

Mdm4 At The Crossroads: Beyond P53 And Mdm2., Dipesh Thapa, Allison St John, Alejandro Parrales, Atul Ranjan, Tomoo Iwakuma

Manuscripts, Articles, Book Chapters and Other Papers

MDM4 (Murine Double Minute 4), also known as MDMX, is a crucial negative regulator of the tumor suppressor p53. MDM4 heterodimerizes with MDM2 to enhance MDM2-mediated ubiquitination and degradation of p53, thereby promoting tumorigenesis. Beyond its canonical role in inhibiting p53 activity, recent studies have revealed diverse p53-independent functions. MDM4 interacts with various proteins, including p73, E2F1, casein kinase 1α, PPARα, and TRIM21 to regulate cell cycle progression, β-catenin-mediated pre-leukemic progression, and ferroptosis independent of p53. In addition, MDM4 functions independently of both p53 and MDM2 by interacting with proteins, such as SMAD family members 3/4, retinoblastoma protein (pRB), p21, …

Thalamic Organization Differentially Contributes To Clinical Conditions In Epilepsy, Qirui Zhang, Sam S. Javidi, Ankeeta Ankeeta, Michael R. Sperling, Zhiqiang Zhang, Joseph I. Tracy

Farber Institute for Neuroscience Faculty Papers

BACKGROUND: The thalamus plays an important role in key clinical conditions of focal temporal lobe epilepsy (TLE), but no investigation has examined whether the same thalamic local and connectome properties shape a patient's status across these different conditions.

METHODS: This retrospective longitudinal MRI study used resting-state fMRI and structural imaging to identify whole-brain focal/regional and connectome-level features associated with six binary clinical conditions of TLE (pre/post-surgery, seizure and neurocognitive outcomes, pathology, seizure subtype, and SOZ lateralization) in 91 patients across two centers (age range: 15-65 years) and 85 matched healthy participants (age range: 18-60 years).

RESULTS: Across conditions, relative to …

Genome-Wide Crispr Screen Identifies A Cytokine-Enhancer Circuit Driving Hif-2Α Activation In Renal Cancer, Jun Fang, Jeremy M Simon, Tao Wang, Yunpeng Gao, Xianju Bi, Lianxin Hu, Chengheng Liao, Cheng Zhang, Yayoi Adachi, Jin Zhou, Hongyi Liu, Qian Liang, James A Nathan, Ram Mani, James Brugarolas, Qing Zhang

Faculty, Staff and Student Publications

Resistance to HIF-2α inhibitors such as Belzutifan underscores the need to better understand how HIF-2α is transcriptionally regulated in clear cell renal cell carcinoma (ccRCC). Here, we uncover a cytokine-driven enhancer mechanism that sustains HIF-2α expression through the JAK1-STAT3 signaling pathway. Using a genome-wide CRISPR screen in VHL-deficient ccRCC cells, we identified SOCS3 as a key negative regulator of HIF-2α. Mechanistically, loss of SOCS3 activates JAK1-STAT3 signaling, leading to the recruitment of STAT3 to distal enhancers upstream of EPAS1 that physically loop to its promoter to drive HIF-2α transcription. This cytokine-enhancer circuit was recapitulated in ccRCC patient samples and functionally …

Receptor-Mediated Drug Delivery: Redefining Targeted Drug Conjugates In Oncology, Keon Niles Jafari, Charlene Chai, Shelby Kim, Kamaljit Kaur

Pharmacy Faculty Articles and Research

Targeted drug delivery (TDD), specifically through targeting ligand–drug conjugates, has reshaped oncology by enabling selective delivery of cytotoxic payloads to cancer cells while minimizing uptake by normal tissues. A key approach relies on exploiting overexpressed cell surface receptors (CSRs) to enable selective uptake of drug conjugates via receptor-mediated endocytosis. This review delineates four clinically validated CSRs (HER2, Trop-2, Nectin-4, and SSTR2) with several FDA-approved drug conjugates. Furthermore, emerging CSRs (EGFR, DLL3, and keratin 1) that may support next-generation TDD platforms for cancer treatment are also highlighted. We discuss how CSR type, density on cancer cells, and its mechanism of endocytosis, …

Faculty, Staff and Students Publications

Greater adherence to plant-based diets is associated with health benefits. Dietary intake can modify DNA methylation patterns, but it is unknown whether plant-based diets in a largely non-vegetarian population are associated with DNA methylation-based epigenetic aging measures. We examined the associations between 4 different types of plant-based diets indices (PDI) [overall PDI, provegetarian diet, healthy PDI, and unhealthy PDI] and epigenetic aging. We used data from the Atherosclerosis Risk in Communities (ARIC) Study (N=2,810) and National Health and Nutrition Examination Survey (NHANES, N=2,056). PDIs negatively scored higher intake of animal products and positively scored higher intake of all or selected …

Sepsis-Triggered Proteolysis Of Profibrinolytic Annexin A2 Associated With Microvasculopathy-Related Organ Dysfunction, Hana I. Lim, Michael Bender, Huigen Chen, Frances M. West, Julio Lanfranco, Dena Almeida, Katherine A. Hajjar

Division of Pulmonary, Allergy, and Critical Care Medicine Faculty Papers

Sepsis is a systemic inflammatory disorder marked by dysregulated inflammation and coagulopathy. Annexin A2 (A2), a profibrinolytic protein, assembles plasminogen and tissue plasminogen activator on cell surfaces, thereby maintaining vascular patency. However, its role in human sepsis has remained poorly defined. We investigated whether A2 undergoes qualitative or quantitative modification during human sepsis with associated end-organ dysfunction. Peripheral blood mononuclear cells and plasma were collected from 65 patients with sepsis and 27 healthy controls. A2 expression and integrity were evaluated with cell surface plasmin generation using immunoblot and fluorometric assays. Both A2 integrity and plasmin generation were significantly reduced in …

Fibrinogen-Bmal1 Signaling As A Therapeutic Target To Limit Aortic Dissection By Preserving Vsmc Contractility, Xiaohan Zhong, Dongjie Li, Yuanfei Zhao, Lu Dai, Jinzhang Li, Zhiqi Ji, Bojing Zuo, Hongshan Liu, Haixia Huang, Wei Wang, Haiyang Li, Yuyong Liu, Ming Gong, Xin-Liang Ma, Wenjian Jiang, Meili Wang, Hongjia Zhang

Department of Emergency Medicine Faculty Papers

Aortic dissection (AD) is a life-threatening vascular disease with a high mortality rate. Surgery is essential in the acute phase but carries significant risks, whereas elective surgery during the chronic phase yields better outcomes. However, no pharmacological therapy has been proven effective in slowing AD progression. In our recent pilot clinical study, an association between higher plasma fibrinogen levels and improved clinical outcomes was observed in AD patients, suggesting a potential protective role of fibrinogen. However, direct evidence supporting this hypothesis is lacking. In this study, a population-based analysis of nonsurgically managed patients with acute AD revealed a distinct association: …

Department of Emergency Medicine Faculty Papers

BACKGROUND:  Acute myocardial ischemia/reperfusion (MI/R) increases risk for cognitive decline, yet the underlying mechanisms mediating heart-brain communication remain poorly understood. Small extracellular vesicles (sEVs) have emerged as novel long-range signaling mediators and may play a critical role.

METHODS: MI/R was induced by transient ligation of the left anterior descending artery. Cognitive performance was assessed using multiple behavioral tests. sEVs derived from cardiomyocytes were labeled to track their distribution and cellular uptake in the brain. Heart and brain tissues were analyzed for microRNAs (miRNAs) expression using bioinformatics, qPCR, and RNAScope. The role of specific miRNAs was investigated through genetic inhibition of …

Neurobiological Pathways Underlying Brain Tumor Progression: Basis For Oncogenicity And Opportunities For Immunotherapeutic Intervention, Carrie E. Andrews, Jenny Zilberberg, Raul Perez-Olle, David Andrews, Mark A. Exley

Department of Neurosurgery Faculty Papers

Both primary and metastatic brain tumors rely on signals from the surrounding environment for their survival and progression. In particular, the most common and lethal brain cancer, glioblastoma (GBM), derived from glial cells (astrocytes or microglia), has been shown to integrate into synaptic networks and to receive paracrine signals from neighbouring tumor microenvironment (TME) cells. There is increasing evidence that metastatic disease in the brain exhibits similar behavior. The TME both maintains malignant cells and is maintained by them, a process that relies on cancer stem cells (CSCs). These stem cells and their signaling mechanisms, including in the case of …
