Small-Molecule Ccr4 Antagonists In Cutaneous T-Cell Lymphoma, José S Enriquez, Xiaohong Wang, Loka Reddy Velatooru, Wei Han, Pedram Bijani, Xiao Ni

Faculty, Staff and Student Publications

Mycosis fungoides (MF) and Sézary syndrome (SS) are two most common types of cutaneous T-cell lymphoma (CTCL). Despite advances in understanding the pathogenesis of MF and SS, effective treatments remain limited. CC chemokine receptor-4 (CCR4) is highly expressed on CTCL cells and serves as a great therapeutic target. Mogamulizumab, an FDA-approved anti-CCR4 antibody, has shown efficacy in treating MF/SS; however, its side effects have raised concerns, underscoring the need for more effective and less toxic CCR4-targeted therapies. Although small-molecule CCR4 antagonists have been studied in other diseases involving CCR4⁺ Th2 cells and regulatory T cells, their effects in CTCL …

Characterization Of Stealth Liposome-Based Nanoparticles Encapsulating Acat1/Soat1 Inhibitor F26: Potential Therapeutics For Niemann-Pick Type C And Other Neurodegenerative Diseases., Junghoon Lee

Dartmouth College Ph.D Dissertations

Cholesterol dysregulation is implicated in neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson’s disease (PD), Huntington’s disease (HD) and Niemann-Pick type C disease (NPCD). This study focused on evaluating the potent ACAT1 inhibitor, F26, as a therapeutic strategy for NPCD. F26 demonstrated superior ACAT1 inhibition and efficacy compared to the previously studied inhibitor, F12511, both in vitro and in vivo. Notably, F26 exhibited enhanced pharmacokinetic properties, including prolonged duration of action and better brain retention, making it a more promising candidate for treating neurodegenerative diseases.

F26 was encapsulated in a liposome-based nanoparticle system, DSPE-PEG2000 with phosphatidylcholine (PC), for enhancing its …

Behavioral And Neural Evidence For Perceptual Inference Of Position, Sharif Saleki

Dartmouth College Ph.D Dissertations

Extensive neuroscientific research has advanced our knowledge of the mechanisms involved in the detection and recognition of visual stimuli. However, to guide flexible behavior in a changing world, the brain must also construct stable and coherent perceptual representations from retinal images that are often ambiguous. To resolve ambiguities and uncertainties, the visual system combines its input with other sources of information such as context and prior knowledge to infer the most likely interpretation of a scene. Thus, perception is inherently an inferential process that goes beyond simple detection or recognition of stimuli. Although inference has been studied in many areas …

The Role Of The Basolateral Nuclear Complex & Central Nucleus Of The Amygdala In Fear-Conditioned Responses To External Stimuli And Anxiety Responses, Oluwaseyi A. Adelakun

Senior Theses

This thesis reviews the role of the amygdala, particularly the basolateral nuclear complex (BLA) and central nucleus (CeA), in fear-conditioned responses and generalized anxiety disorder (GAD). By investigating the neurological and physiological mechanisms that influence the amygdala’s fear and anxiety responses, further connections can be made between this region and other notable brain regions, like the prefrontal cortex (PFC). We review both human and rodent models to explore the overlap between the two and explore various therapeutic interventions that regulate amygdalar activity and therefore mitigate anxiety symptoms. Key research into the patient SM, who lacks fear responses due to bilateral …

Blurring Boundaries: A Proposed Research Agenda For Ethical, Legal, Social, And Historical Studies At The Intersection Of Infectious And Genetic Disease, Seethal Jose, Juli Bollinger, Gail Geller, Jeremy Greene, Leslie Meltzer Henry, Brian Hutler, Eric Thomas Juengst, Jeffrey Kahn, Anna Mastroianni, Graham Mooney

Articles

Contemporary understanding of the mechanisms of disease increasingly points to examples of “genetic diseases” with an infectious component and of “infectious diseases” with a genetic component. Such blurred boundaries generate ethical, legal, and social issues and highlight historical contexts that must be examined when incorporating host genomic information into the prevention, outbreak control, and treatment of infectious diseases.

We present national implementation progress on international and regional legal obligations up to 2020 and discuss recent developments in shark conservation management in the region. This study provides insights into the complexity of implemented measures and actions related to shark conservation and fisheries management, governed by various legal instruments. Measures were primarily identified through regional fisheries management organisations (RFMO) reports, reports of Focal Point meetings under the Barcelona Convention, and national reports under the Convention on Biological Diversity (CBD) and the Convention on Migratory Species (CMS). A total of 208 implemented measures across different categories were found. The most common …

Did Stalinism Pave The Way For The Rise Of The Marcos Dictatorship? A Review Of Joseph Scalice’S The Drama Of Dictatorship, Jervy C. Briones, Karlo Mikhail I. Mongaya

Journal Article

Joseph Scalice’s The Drama of Dictatorship: Martial Law and the Communist Parties of the Philippines (2023) offers arguably one of the most definitive Trotskyist critiques of the historical legacy of the Philippine communist movement. Through extensive archival research, Scalice interprets the split between the Partido Komunista ng Pilipinas (PKP) and the Communist Party of the Philippines (CPP) as a local expression of the Sino-Soviet split, arguing that both parties acted as class collaborators by aligning with rival factions of the Filipino elite. This review article critically engages with Scalice’s historical claims from an anti-imperialist, Marxist, and non-sectarian perspective. While his …

Impacts Of Ing4-Deficiency On Hematopoietic Stem And Progenitor Cells & Characterizing The Concerns Of Novice Stem Graduate Teaching Assistant, Georgina Alice Anderson

Theses and Dissertations

The hematopoietic compartment is tasked with the establishment and maintenance of the entire blood program in steady-state and in response to stress. Key to this process are hematopoietic stem cells (HSCs), which possess the unique ability to self-renew and differentiate to replenish blood cells throughout an organism’s lifetime. Recent work has illustrated the vast mechanisms involved in regulating stress-induced hematopoiesis, including cytokine-mediated lineage bias, gene signature changes in aged HSCs associated with chronic inflammation, the impact of clonal hematopoiesis and stress tolerance. Inhibitor of Growth 4 (Ing4) has been identified as a critical regulator of HSC homeostasis. We show that …

Mitochondrial Function In The Maternal Brain: A New Perspective On Gestational Stress And Pathology Of Postpartum Depression, Erin Rene Gorman-Sandler

Theses and Dissertations

Postpartum depression (PPD) is a major psychiatric complication of childbirth, affecting up to 20% of mothers, yet remains understudied. Mitochondria, dynamic organelles crucial for cell homeostasis and energy production, share links with many of the proposed mechanisms underlying PPD pathology. Brain mitochondrial function is affected by stress, a major risk factor for development of PPD, and is linked to avoidance and social behaviors. Considering the importance of mitochondria in regulating brain function and behavior, we hypothesized that mitochondrial dysfunction is associated with behavioral alterations in a chronic stress-induced rat model of PPD. Chronic mild unpredictable (CMUS) stress during late gestation …

Plankton Dynamics In A Temperate Estuary:Size Structure And Trophic Implications, Nayan Mallick

Theses and Dissertations

Estuarine ecosystems provide goods and services to around 45% of the entire human population. In recent times, these ecosystems have been severely affected by multiple stressors such as pollution, eutrophication, harmful algal blooms, sea level rise, and, most importantly, climate change. Increasing temperature associated with climate change can have pervasive impacts throughout the ecosystem’s functions and processes. Plankton, a conspicuous member of estuarine food web, are among the first to respond to the changes in temperature due to their high sensitivity to changing environmental conditions.

In this dissertation, I investigated the plankton dynamics in an estuarine ecosystem through a combination …

Popular Justice Or Populist Justice? Penal Populism And Its Impact On Democracy, Kuan-Wu Chen

Theses and Dissertations

Populism, a pervasive phenomenon in contemporary politics, manifests as an anti-establishment, anti-pluralistic, morally charged framing that advocates for direct rule between leader and populace. Among its variants, penal populism emerges as a particularly concerning manifestation. It is characterized by a leader's deployment of panicking, punitive, and politically targeted rhetoric to enhance social control and accrue political capital rather than address crime prevention. This research argues that penal populism poses the most significant threat to democratic rule, as evidenced by theoretical, framing, and mobilization analyses. A novel categorization of populist variants is proposed based on dimensions of social categorization and exclusivity. …

We aimed to evaluate the research output and create a narrative on global vaccine …

Dual Targeting Macrophages And Microglia Is A Therapeutic Vulnerability In Models Of Pten-Deficient Glioblastoma, Yang Liu, Junyan Wu, Hinda Najem, Yiyun Lin, Lizhi Pang, Fatima Khan, Fei Zhou, Heba Ali, Amy B Heimberger, Peiwen Chen

Faculty, Staff and Student Publications

Tumor-associated macrophages and microglia (TAMs) are critical for tumor progression and therapy resistance in glioblastoma (GBM), a type of incurable brain cancer. We previously identified lysyl oxidase (LOX) and olfactomedin like-3 (OLFML3) as essential macrophage and microglia chemokines, respectively, in GBM. Here, single-cell transcriptomics and multiplex sequential immunofluorescence followed by functional studies demonstrate that macrophages negatively correlate with microglia in the GBM tumor microenvironment. LOX inhibition in PTEN-deficient GBM cells upregulates OLFML3 expression via the NF-κB-PATZ1 signaling pathway, inducing a compensatory increase of microglia infiltration. Dual targeting macrophages and microglia via inhibition of LOX and the CLOCK-OLFML3 axis generates potent …

NRG Oncology's Developmental Therapeutics and Radiation Therapy Subcommittee assembled an interdisciplinary group of investigators to address barriers to successful early phase clinical trials of novel combination therapies involving radiation. This Policy Review elucidates some of the many challenges associated with study design for early phase trials combining radiotherapy with novel systemic agents, which are distinct from drug-drug combination development and are often overlooked. We also advocate for potential solutions that could mitigate or eliminate some of these barriers, providing examples of specific clinical trial designs that could help facilitate efficient and effective evaluation of novel drug-radiotherapy combinations.

Herein, we report a case of a collision tumor involving a multinodular and vacuolating neuronal tumor (MVNT) and a diffuse astrocytoma. A collision tumor between these two entities has not previously been reported. The patient is a 35-year-old woman who presented with new-onset hearing loss and ringing in her right ear. Magnetic resonance imaging identified a non-enhancing mass involving the gray matter and subcortical white matter of the left middle frontal gyrus. Additionally, tiny clustered nodules were noted along the underlying subcortical ribbon and superficial subcortical white matter of the left superior frontal gyrus. The patient underwent a left frontal …

A Molecular Switch From Tumor Suppressor To Oncogene In Er+Ve Breast Cancer: Role Of Androgen Receptor, Jak-Stat, And Lineage Plasticity, Sarah Asemota, Wendy Effah, Jeremiah Holt, Daniel Johnson, Linnea Cripe, Suriyan Ponnusamy, Thirumagal Thiyagarajan, Yekta Khosrosereshki, Dong-Jin Hwang, Yali He, Brandy Grimes, Martin D Fleming, Frances E Pritchard, Ashley Hendrix, Meiyun Fan, Abhinav Jain, Hyo Young Choi, Liza Makowski, D Neil Hayes, Duane D Miller, Lawrence M Pfeffer, Balaji Santhanam, Ramesh Narayanan

Cancers develop resistance to inhibitors of oncogenes mainly due to target-centric mechanisms such as mutations and splicing. While inhibitors or antagonists force targets to unnatural conformation contributing to protein instability and resistance, activating tumor suppressors may maintain the protein in an agonistic conformation to elicit sustainable growth inhibition. Due to the lack of tumor suppressor agonists, this hypothesis and the mechanisms underlying resistance are not understood. In estrogen receptor (ER)-positive breast cancer (BC), androgen receptor (AR) is a druggable tumor suppressor offering a promising avenue for this investigation. Spatial genomics suggests that the molecular portrait of AR-expressing BC cells in …

Despite the potential of oral immunotherapy against food allergy, adverse reactions and loss of desensitization hinder its clinical uptake. Dysbiosis of the gut microbiota is implicated in the increasing prevalence of food allergy, which will need to be regulated to enable for an effective oral immunotherapy against food allergy. Here we report an inulin gel formulated with an allergen that normalizes the dysregulated ileal microbiota and metabolites in allergic mice, establishes allergen-specific oral tolerance and achieves robust oral immunotherapy efficacy with sustained unresponsiveness in food allergy models. These positive outcomes are associated with enhanced allergen uptake by antigen-sampling dendritic cells …

The Tragedy Of Our Trajectory, Marisola Xhelili Ciaccio

Dissertations (1934 -)

In this project, I argue that the trajectory of Western European civilization has resulted in increasingly tragic predicaments that are not to be taken as given features of being human. Though both Ancient Western and Eastern wisdom traditions concur that suffering is a part of life, the point of living is not to suffer but to learn to overcome it and flourish. But because the purported successes of Western “progress” necessarily depend on structural oppression, and oppression produces superfluous sufferings that interfere with our capacities to actualize our freedom and flourish, they ultimately make us all worse-off. Reflecting on such …

Il-22 Resolves Masld Via Enterocyte Stat3 Restoration Of Diet-Perturbed Intestinal Homeostasis, Peng Zhang, Junlai Liu, Allen Lee, Irene Tsaur, Masafumi Ohira, Vivian Duong, Nicholas Vo, Kosuke Watari, Hua Su, Ju Youn Kim, Li Gu, Mandy Zhu, Shabnam Shalapour, Mojgan Hosseini, Gautam Bandyopadhyay, Suling Zeng, Cristina Llorente, Haoqi Nina Zhao, Santosh Lamichhane, Siddharth Mohan, Pieter C Dorrestein, Jerrold M Olefsky, Bernd Schnabl, Pejman Soroosh, Michael Karin

The exponential rise in metabolic dysfunction-associated steatotic liver disease (MASLD) parallels the ever-increasing consumption of energy-dense diets, underscoring the need for effective MASLD-resolving drugs. MASLD pathogenesis is linked to obesity, diabetes, "gut-liver axis" alterations, and defective interleukin-22 (IL-22) signaling. Although barrier-protective IL-22 blunts diet-induced metabolic alterations, inhibits lipid intake, and reverses microbial dysbiosis, obesogenic diets rapidly suppress its production by small intestine-localized innate lymphocytes. This results in STAT3 inhibition in intestinal epithelial cells (IECs) and expansion of the absorptive enterocyte compartment. These MASLD-sustaining aberrations were reversed by administration of recombinant IL-22, which resolved hepatosteatosis, inflammation, fibrosis, and insulin resistance. Exogenous …

Astrocyte-Induced Cdk5 Expedites Breast Cancer Brain Metastasis By Suppressing Mhc-I Expression To Evade Immune Recognition, Arseniy E Yuzhalin, Frank J Lowery, Yohei Saito, Xiangliang Yuan, Jun Yao, Yimin Duan, Jingzhen Ding, Sunil Acharya, Chenyu Zhang, Abigail Fajardo, Hao-Nien Chen, Yongkun Wei, Yutong Sun, Lin Zhang, Yi Xiao, Ping Li, Philip L Lorenzi, Jason T Huse, Huihui Fan, Zhongming Zhao, Mien-Chie Hung, Dihua Yu

Brain metastases (BrMs) evade the immune response to develop in the brain, yet the mechanisms of BrM immune evasion remains unclear. This study shows that brain astrocytes induce the overexpression of neuronal-specific cyclin-dependent kinase 5 (Cdk5) in breast cancer-derived BrMs, which facilitates BrM outgrowth in mice. Cdk5-overexpressing BrMs exhibit reduced expression and function of the class I major histocompatibility complex (MHC-I) and antigen-presentation pathway, which are restored by inhibiting Cdk5 genetically or pharmacologically, as evidenced by single-cell RNA sequencing and functional studies. Mechanistically, Cdk5 suppresses MHC-I expression on the cancer cell membrane through the Irf2bp1-Stat1-importin α-Nlrc5 pathway, enabling BrMs to …

Targeting The Peripheral Neural-Tumour Microenvironment For Cancer Therapy, Dan Yaniv, Brandi Mattson, Sebastien Talbot, Frederico O Gleber-Netto, Moran Amit

Faculty, Staff and Student Publications

As the field of cancer neuroscience expands, the strategic targeting of interactions between neurons, cancer cells and other elements in the tumour microenvironment represents a potential paradigm shift in cancer treatment, comparable to the advent of our current understanding of tumour immunology. Cancer cells actively release growth factors that stimulate tumour neo-neurogenesis, and accumulating evidence indicates that tumour neo-innervation propels tumour progression, inhibits tumour-related pro-inflammatory cytokines, promotes neovascularization, facilitates metastasis and regulates immune exhaustion and evasion. In this Review, we give an up-to-date overview of the dynamics of the tumour microenvironment with an emphasis on tumour innervation by the peripheral …

Antiangiogenic Tyrosine Kinase Inhibitors Have Differential Efficacy In Clear Cell Renal Cell Carcinoma In Bone, Stefan Maksimovic, Nina C Boscolo, Ludovica La Posta, Sergio Barrios, Mohammad Jad Moussa, Emanuela Gentile, Pedro I Pesquera, Wenjiao Li, Jianfeng Chen, Javier A Gomez, Akshay Basi, Jared K Burks, Christopher Alvarez-Breckenridge, Jianjun Gao, Matthew T Campbell, Eleonora Dondossola

Clear cell renal cell carcinoma (ccRCC) is the most prevalent kidney neoplasm; bone metastasis (BM) develops in 35% to 40% of metastatic patients and results in substantial morbidity and mortality, as well as medical costs. A key feature of ccRCC is the loss of function of the von Hippel-Lindau protein, which enhances angiogenesis via vascular endothelial growth factor release. Consequently, antiangiogenic tyrosine kinase inhibitors (TKI) emerged as a treatment for ccRCC. However, limited data about their efficacy in BM is available, and no systematic comparisons have been performed. We developed mouse models of bone and lung ccRCC tumors and compared …

A Novel Deep Learning Model For Tool Wear Estimation Of Cutting Tools, Ahmed Darwish

Sustainable Machine Intelligence Journal

In cutting tools, tool wear may result in low-quality surfaces and precision in dimensional measurement. Tool wear may additionally result in fractures and harm to the workpieces over operations. It's critical to track tool wear in life in order to avoid these situations. This research proposes a data-driven deep learning strategy to improve the accuracy of cutting tool wear estimates. This technique combines a Gated Recurrent Unit (GRU) with a Convolutional Neural Network (CNN). In order to circumvent the problems associated with single-domain features that lack appropriate tool status data, a multi-domain combination technique was used to develop candidate features. …
