Background: KMT2A rearrangements occur in ~10% of acute myeloid leukemia (AML) cases and are critical for classification, risk stratification, and use of targeted therapy. However, insertions involving the KMT2A gene can evade detection using chromosomal analysis and/or fluorescence in situ hybridization (FISH).

Methods: We present a case of a 22-year-old woman with acute monoblastic leukemia harboring a cryptic KMT2A::AFDN fusion identified by RNA sequencing. Initial FISH showed a 3' KMT2A deletion, while conventional karyotyping and the automated bioinformatic pipeline for optical genome mapping (OGM) did not identify the canonical translocation.

Results: To resolve these discrepancies, metaphase KMT2A FISH (break-apart fusion …

Alk Drives Neuroblastoma Tumorigenesis Via Upregulation Of Postn And Activation Of Wnt And Stat3 Signaling, Miller Huang, Wanqi Fang, Alvin Farrel, Linwei Li, Tania Porras Corredor, Shahab Asgharzadeh, John Maris, William A. Weiss

Research Symposium

Background: Neuroblastoma (NB) is the most common extracranial solid tumor in children. Two of the earliest known genetic drivers of NB are the oncogene MYCN and receptor tyrosine kinase ALK. While animal models show MYCN and mutationally active ALK F1174L can accelerate NB tumorigenesis, the mechanism of this cooperation is unknown. This study applied a human stem cell-based model to elucidate how ALK cooperates with MYCN to accelerate tumorigenesis of NB.

Methods: Induced pluripotent stem cells (iPSCs) were engineered with doxycycline-inducible MYCN and constitutively active ALKF1174L. These iPSCs were differentiated into trunk neural crest cells (tNCCs) and orthotopically transplanted into …


Mechanisms Of Macrophage Metabolic Activation And Paracrine Wnt Signaling In The Pathogenesis Of Systemic Sclerosis, Emily Ann Morris Mar 2025

Mechanisms Of Macrophage Metabolic Activation And Paracrine Wnt Signaling In The Pathogenesis Of Systemic Sclerosis, Emily Ann Morris

Dartmouth College Ph.D Dissertations

Systemic sclerosis (SSc) is a chronic autoimmune disease of unknown etiology. We have previously shown that macrophages (MØs) play a critical role in its pathogenesis; however, the mechanisms driving MØ activation in SSc remain poorly understood. This dissertation investigates the molecular signaling pathways and biochemical mechanisms underlying profibrotic MØ activity in SSc.

First, I identify a novel MØ-specific effect of mycophenolate mofetil (MMF), the standard-of-care treatment for SSc. While MMF is a well characterized lymphostatic, my findings demonstrate that its active metabolite, mycophenolic acid (MPA), is also capable of directly inhibiting myeloid viability and profibrotic MØ activation by suppressing de …

Industrialization adversely affects the gut microbiome and predisposes individuals to chronic non-communicable diseases. We tested a microbiome restoration strategy comprising a diet that recapitulated key characteristics of non-industrialized dietary patterns (restore diet) and a bacterium rarely found in industrialized microbiomes (Limosilactobacillus reuteri) in a randomized controlled feeding trial in healthy Canadian adults. The restore diet, despite reducing gut microbiome diversity, enhanced the persistence of L. reuteri strain from rural Papua New Guinea (PB-W1) and redressed several microbiome features altered by industrialization. The diet also beneficially altered microbiota-derived plasma metabolites implicated in the etiology of chronic non-communicable diseases. Considerable …

Progressive Multifocal Leukoencephalopathy (Pml) Induced By Jc Virus: A Case Report And Review Of Clinical Implications, Hugo Zamarron, Roberto Cruz Mar 2025

Progressive Multifocal Leukoencephalopathy (Pml) Induced By Jc Virus: A Case Report And Review Of Clinical Implications, Hugo Zamarron, Roberto Cruz

Research Symposium

Background: Progressive multifocal leukoencephalopathy (PML) is a rare but serious demyelinating disease of the central nervous system, caused by the John Cunningham (JC) virus. While the JC virus is common in the general population, it remains dormant in healthy individuals but can reactivate in immunocompromised patients, particularly those with HIV/AIDS or undergoing immunosuppressive treatments for organ transplants or autoimmune conditions. The virus attacks oligodendrocytes, leading to demyelination and significant neurological deficits. Immunosuppressive therapies such as natalizumab, rituximab, and mycophenolate increase the risk of PML. Diagnosing PML is challenging as its symptoms—focal neurological deficits, sensory-motor issues, and visual disturbances—overlap with conditions …

Factors Driving Adolescent Tuberculosis Incidence By Age And Sex In 30 High-Tuberculosis Burden Countries: A Mathematical Modelling Study, Silvia S Chiang, Megan B Murray, Alexander W Kay, Peter J Dodd

Faculty, Staff and Students Publications

INTRODUCTION: During adolescence, tuberculosis incidence rises, with a greater increase in males compared with females. Tuberculosis notifications and estimates infrequently disaggregate adolescent age groups. Moreover, the factors that drive the increases in overall incidence and the male-to-female (MF) ratio remain unclear.

METHODS: We constructed a mechanistic model to estimate cumulative Mycobacterium tuberculosis infection and tuberculosis disease incidence in the WHO’s 30 high-tuberculosis burden countries (HBCs), which represent 86%–90% of global tuberculosis incidence. We derived infection risk from tuberculosis prevalence and assortative social mixing based on sex and age (10–14 years vs 15–19 years old). We adjusted age subgroup-specific risks of …

Impact Of Diabetes On Fall Related Lower Limb Fractures, Bryce M. Bellon, Daniel Salinas, Patrick De La Torre Shutz, Hunter Butler, Sean Corcoran, Kelsey Baker Mar 2025

Impact Of Diabetes On Fall Related Lower Limb Fractures, Bryce M. Bellon, Daniel Salinas, Patrick De La Torre Shutz, Hunter Butler, Sean Corcoran, Kelsey Baker

Research Symposium

Background: Diabetes is a disorder that affects many Americans, characterized primarily by hyperglycemia due to either insulin resistance or lack of insulin secretion. This condition not only impacts blood sugar levels but also has significant effects on bone health. In diabetes, bone density is often decreased due to reduced osteoblast activity, which is responsible for bone formation, and increased osteoclast activity, which leads to bone resorption. This imbalance accelerates the breakdown of bone. Additionally, diabetics frequently suffer from lower extremity arterial disease (LEAD), which results in poor vascularization of the lower limbs. These factors contribute to an increased risk of …
