Limbic predominant age-related TDP-43 encephalopathy neuropathologic change (LATE-NC) is highly prevalent in late life and a common co-pathology with Alzheimer's disease neuropathologic change (ADNC). LATE-NC is a slowly progressive, amnestic clinical syndrome. Alternatively, when present with ADNC, LATE-NC is associated with a more rapid course. With the emergence of anti-amyloid therapeutics, discrimination of LATE-NC from ADNC is critical and will lead to greater clinical recognition of amnestic patients without ADNC. Furthermore, co-pathology with LATE-NC may influence outcomes of these therapeutics. Thus there is a need to identify patients during life with likely LATE-NC. We propose criteria for clinical diagnosis of …

A Biomechanical Study Of Neck Strength And Impact Dynamics On Head And Neck Injury Parameters, Rahid Zaman, Mohammad Ibrahim Hossain, Ahmed Zubayer Raiyan, Shuvo Chowdhury, Aaron Jackson, Arthur Thomas Koster, Ashfaq Adnan

Faculty, Staff and Student Publications

Introduction: Head and neck injuries, including traumatic brain injuries (TBI), are a leading cause of disability and death worldwide. It affects millions of people worldwide, from automobiles to sports to military personnel. This study investigates the influence of impact locations, severities, and neck strength on head and neck injury parameters using a musculoskeletal head-neck model in OpenSim software.

Methods: We hypothesize that eccentric impacts, particularly those on the anterolateral side, increase GAMBIT and Neck Injury Criteria (NIC) due to elevated rotational accelerations, and that higher neck strength mitigates GAMBIT and NIC under these impacts. To test our hypotheses, we investigated …

New Insights Into The Mechanisms Of Electroconvulsive Therapy In Treatment-Resistant Depression, Ana C Ruiz, Abdul Haseeb, William Baumgartner, Edison Leung, Giselli Scaini, Joao Quevedo

Faculty, Staff and Student Publications

Electroconvulsive therapy (ECT) remains one of the most effective interventions for treatment-resistant depression (TRD), particularly in cases involving severe symptomatology, suicidality, or psychotic features. Despite advancements aimed at enhancing the safety and cognitive tolerability of ECT, concerns about cognitive side effects continue to limit its broader acceptance. A deeper understanding of the mechanisms underlying ECT is therefore critical for refining its use and maximizing clinical outcomes. Through a narrative review of recent literature, this paper synthesizes current evidence comparing the efficacy of ECT, ketamine, and repetitive transcranial magnetic stimulation (rTMS) in the treatment of TRD. Then, the review delves into …

Circulating Fibroblast Growth Factor 21 (Fgf21) As A Prognostic And Diagnostic Biomarker In Hepatocellular Carcinoma, Joe R Eid, Merih Yalciner, Lianchun Xiao, Ryan Sun, Mahesh Kumar Kannan, Manal Hassan, Asif Rashid, Shadi Chamseddine, Hop S Tran Cao, Hesham M Amin, Ahmed O Kaseb

Faculty, Staff and Student Publications

Purpose: Fibroblast growth factor 21 (FGF21) is a hormone synthesized and released by liver cells. Deficiency in FGF21 has been shown to be associated with steatosis, inflammation, fibrosis, and increased risk of hepatocellular carcinoma (HCC) development. Moreover, recent evidence suggests that elevated FGF21 levels may paradoxically correlate with worse outcomes in HCC. We aimed to evaluate the association between serum FGF21 levels, clinicopathological parameters, and overall survival (OS) in HCC patients.

Patients and methods: From 2001 to 2014, newly diagnosed HCC patients were recruited as part of an IRB-approved protocol. Blood samples were prospectively collected and a CLIA-certified lab measured …

Faculty, Staff and Student Publications

Background: New therapies are urgently needed for patients with osteosarcoma (OS). STAT3 and CD47 are potential therapeutic target in OS. Here we investigated the therapeutic activity of the orally bioavailable STAT3 inhibitor, WP1066, and anti-CD47 antibody using OS mouse models.

Methods: Cytotoxic effect of WP1066 against OS cell lines and its immunomodulatory effects were evaluated in vitro. Experimental metastasis and orthotopic syngeneic mouse models were used to investigate the therapeutic efficacy of WP1066 and anti-CD47 antibody. Further flow cytometric analysis was performed.

Results: STAT3 was constitutively activated in multiple human and mouse OS cell lines. WP1066 suppressed STAT3 activation …

Cord Blood-Derived Ink T Cells As A Platform For Allogeneic Car T Cell Therapy, Maison Grefe, Abel Trujillo-Ocampo, Jelita Clinton, Hong He, Ling Yu, Dan Li, Qing Ma, Elizabeth J Shpall, Jeffrey J Molldrem, Jin S Im

Faculty, Staff and Student Publications

CD1d-restricted invariant Natural Killer (iNK) T cells are a suitable candidate for allogeneic Chimeric Antigen Receptor (CAR) T cell therapy as they do not cause graft-versus-host disease (GvHD) due to the monomorphic nature of CD1d proteins. However, the phenotypic and functional heterogeneity of iNK T cells from adult donors (AD) may lead to the inconstant CAR-iNK T cell products. Cord blood-derived (CB) iNK T cells, in contrast, exhibit inter-donor homogeneity in phenotype including uniform CD4 expression and are enriched in memory iNK T cell populations. Thus, we evaluated the preclinical therapeutic potential of iNK T cells derived from cord blood …

BACKGROUND & AIMS: GD2, a member of the ganglioside (GS) family (sialic acid-containing glycosphingolipids), is a potential biomarker of cancer stem cells (CSC) in several tumours. However, the possible role of GD2 and its biosynthetic enzyme, GD3 synthase (GD3S), in intrahepatic cholangiocarcinoma (iCCA) has not been explored.

METHODS: The stem-like subset of two iCCA cell lines was enriched by sphere culture (SPH) and compared to monolayer parental cells (MON). GS profiles were evaluated by chromatography, after feeding with radioactive sphingosine. Membrane GD2 expression was evaluated by FACS, and the expression of enzymes of GS biosynthesis was analysed by RT-qPCR. The …

18 Kda Translocator Protein (Tspo) Is Upregulated In Rat Brain After Peripheral Nerve Injury And Downregulated By Diroximel Fumarate, Rafael A Cazuza, Sever M Zagrai, Anamaria R Grieco, Thomas D Avery, Andrew D Abell, Hsiao-Ying Wey, Marco L Loggia, Peter M Grace

Faculty, Staff and Student Publications

Neuroimmune signaling is a key process underlying neuropathic pain. Clinical studies have demonstrated that 18 kDa translocator protein (TSPO), a putative marker of neuroinflammation, is upregulated in discrete brain regions of patients with chronic pain. However, no preclinical studies have investigated TSPO dynamics in the brain in the context of neuropathic pain and in response to analgesic treatments. We used positron emission tomography-computed tomography (PET-CT) and [18F]-PBR06 radioligand to measure TSPO levels in the brain across time after chronic constriction injury (CCI) of the sciatic nerve in both male and female rats. Up to 10 weeks post-CCI, TSPO expression was …

Patients with chronic lymphocytic leukemia (CLL) respond well to initial treatment with the B-cell lymphoma 2 (BCL2) inhibitor venetoclax. Upon relapse, they often retain sensitivity to BCL2 targeting, but durability of response remains a concern. We hypothesize that targeting both BCL2 and B-cell lymphoma-extra large (BCLXL) will be a successful strategy to treat CLL, including for patients who relapse on venetoclax. To test this hypothesis, we conducted a pre-clinical investigation of LP-118, a highly potent inhibitor of BCL2 with moderate BCLXL inhibition to minimize platelet toxicity. This study demonstrated that LP-118 induces efficient BAK activation, cytochrome C release, and apoptosis …

The Role Of Tgf-Beta Superfamily Members In Immune Homeostasis And Disease, Natalie Eva Nieuwenhuizen, Ioannis Eleftherianos, Piotr Jan Kraj, Maria Semitekolou

Biological Sciences Faculty Publications

[Introduction] The Transforming Growth Factor beta (TGF-beta) superfamily, encompassing molecules such as TGFs, activins, Bone Morphogenetic Proteins (BMPs), Growth/Differentiation Factor (GDFs) and Nodals, represents the largest family of growth and differentiation factors, playing crucial roles in developmental and physiological processes across animal species (1). These molecules are integral to tissue homeostasis and cell fate determination. Among them, TGF-beta is particularly noted for its regulatory influence on immune responses and tissue fibrosis (2, 3). Recent research has expanded our understanding of the immune functions of other superfamily members, including activin A and BMPs (4). These molecules signal through receptor complexes composed …

Department of Medicine Faculty Publications

What drives inflammation-associated tumorigenesis and progression in pancreatic ductal adenocarcinoma (PDAC)? Doublecortin-like kinase 1 (DCLK1) is a central driver of inflammation-associated tumorigenesis, with elevated expression linked to worse clinical outcomes. Two isoforms of DCLK1 possess a unique extracellular domain (ECD). DCLK1 isoform 2 contains two microtubule-binding domains, while isoform 4, lacks the microtubule-binding domains but, plays a pivotal role in tumor progression. We identified novel D-peptides that selectively target this ECD, significantly suppressing PDAC cell proliferation in vitro and tumor growth in xenograft models without inducing cell death. In silico modeling and binding assays revealed DCLK1 isoform 4 interacts with …

This study aims to compare the efficacy of these two techniques in providing pain relief and improving function in patients with refractory ischial bursitis.

Methods: A retrospective analysis was conducted using electronic medical records of nine patients with refractory ischial bursitis treated between April 1, 2023, and November 30, 2024. Patients were categorized based on the injection technique: fluoroscopically guided (n=4) or landmark-based (n=5). Pain relief was assessed at follow-up …

Administration Of Anti-Gfap Antibodies Increases Cgrp Expression And Increases Pain Hypersensitivity In Spinal Cord Injured Animals, Georgene W Hergenroeder, Samuel T Molina, Juan J Herrera

Faculty, Staff and Student Publications

Background: Spinal cord injury (SCI) results in a multitude of cellular and pathological changes including neuronal loss, axonal damage, gliosis, and loss of motor and sensory function. In 40%-70% of patients, SCI can also trigger the development of neuropathic pain. Our previous study demonstrated that SCI patients who developed autoantibodies to glial fibrillary acidic protein (GFAP) were at increased risk for the subsequent development of neuropathic pain. However, whether GFAP autoantibodies (GFAPab) contribute to the development of neuropathic pain after SCI had yet to be examined.

Objective: Using a mid-thoracic contusion model of SCI in male Sprague-Dawley rats, we examined …

Faculty, Staff and Student Publications

Thoracic aortic aneurysm and dissection (TAD) is a life-threatening vascular disorder, and smooth muscle cell mitochondrial dysfunction leads to cell death, contributing to TAD. Accurate measurements of metabolic processes are essential for understanding cellular homeostasis in both healthy and diseased states. While assays for evaluating mitochondrial respiration have been well established for cultured cells and isolated mitochondria, no optimized application has been developed for aortic tissue. In this study, we generate an optimized protocol using the Agilent Seahorse XFe24 analyzer to measure mitochondrial respiration in mouse aortic tissue. This method allows for precise measurement of mitochondrial oxygen consumption in mouse …

Faculty, Staff and Student Publications

AIMS: The haemodynamic physiology of the aortic valve has attracted renewed attention after the introduction of transcatheter aortic valve implantation (TAVI). Understanding normal valve function, especially under stress conditions, permits identification of early pathology and quantification of the extent to which TAVI restores normalcy. We aimed to describe the haemodynamic behaviour of a normal aortic valve during stress via invasive, non-invasive, and computational techniques.

METHODS AND RESULTS: Our cohort included subjects already undergoing invasive coronary angiography for clinical indications. Haemodynamic measurements were made invasively and non-invasively along with dobutamine infusion. Additionally, patient-specific anatomy from computed tomographic imaging served as input …

Prenatal Alcohol Exposure Inhibits Transient Expression Of Autophagy And Synaptic Proteins In Developing Brain, Monica Hampe, Nune Darbinian, Nana Merabova, Armine Darbinyan, Jamal Hamze, Uday Bharai, Yuri Persidsky, Mary F Morrison, Shohreh Amini, Laura Goetzl, Michael E Selzer

Faculty, Staff and Student Publications

Introduction: Neuronal apoptosis and consequent inhibition of autophagy, with loss of synaptic connections are central events in the genesis of fetal alcohol spectrum disorders (FASD). However, studies of molecular mechanisms of autophagy in human fetal brain are limited. Recently, prenatal exposure to EtOH was associated with reduced miRNA-9 levels in fetal brain-derived exosomes (FB- Es) isolated from maternal plasma, which correlated with small eyes, an anatomical hallmark of fetal alcohol syndrome (FAS). Since miR-9 targets several genes that regulate synaptic plasticity, EtOH-induced inhibition of miR-9 could potentially result in dysregulation of genes involved in synaptogenesis/plasticity.

Methods: Rats were fed a …

The Impact Of Peer Observational Learning On Honesty Following A Transgression, Hannah M. Sliman, George H. Noell

Psychology Faculty Publications

Parents and teachers worry about how lying affects children's development and socialization, as research links persistent lying to delinquency, aggression, and conduct issues. To investigate this, we examined two groups: Honest and Praise versus a Control Group, exploring how exposure influenced children's honesty and confession after transgressions. The study aimed to see if observing peers receive praise for honesty could promote truthfulness. Gender's impact on reporting honesty was assessed. Results showed no significant difference in honesty between the HP and CG groups; children confessed at similar rates in both conditions. Gender did not affect honest reporting. These findings differ from …

Enl Mutation And Aml: A New Model That Reveals Oncogenic Condensate’S Function In Leukemogenesis, Zhong Fan, Yanan Jiang, Xiaotian Zhang

Faculty, Staff and Student Publications

Precise regulation of gene expression is essential for proper development and the maintenance of homeostasis in organisms. Studies have shown that some transcriptional regulatory proteins influence gene expression through the formation of dynamic, locally concentrated assemblies known as condensates, while dysregulation of transcriptional condensates was associated with several cancers, such as Ewing sarcoma and AML [Wang Y et al. (2023) Nat Chem Biol 19, 1223-1234; Chandra B et al. (2022) Cancer Discov 12, 1152-1169]. Mutations in the histone acetylation "reader" eleven-nineteen-leukemia (ENL) have been shown to form discrete condensates at endogenous genomic targets, but it remains unclear how ENL mutations …

Nuclear Destabilisation – A Possible Genesis Of Cancer?, Daniel D. Scott, Francesco Bettariga, Marco Ventin, Chris Bishop, Britta Stordal

Research outputs 2022 to 2026

This review examines the increasingly prominent role of mechanics within cancer formation and progression. The extremely varied and contradictory genetic landscape of cancer is in stark contrast to the seemingly universal mechanical characteristics of cancer cells and their tumour microenvironment, and mechanics may be a principal unifying trait of this disease. The tight regulation of innate cell mechanical properties raises the possibility that destabilisation of the cell drives tumour formation in an attempt to restore cell mechanical homeostasis. With losses in cell stiffness more pronounced at the cell nucleus, we hypothesise that destabilisation occurs within the nucleus, likely within the …

Reduced Set-Shifting Processing Speed In Male Rats Following Low Dose (10 Cgy) Proton Exposure, Hui Ho Vanessa Chang, Gyutae Kim, Kyu-Sung Kim, Richard A. Britten

Center for Integrative Neuroscience and Inflammatory Diseases (CINID) Faculty Publications

Space radiation (SR) exposure poses significant biomedical risks, including effects on the central nervous system (CNS). These risks are particularly relevant to cognitive function during long-duration space missions. One critical cognitive skill is decision-making, which requires attentional set-shifting (ATSET)—the ability to quickly assess problems, evaluate options, and select the best actions. Previous studies have shown that exposure to However, the impact of low LET (< 1 keV/μm) protons, which significantly contribute to the total radiation flux astronauts encounter within spacecraft, on ATSET performance is unknown. To address this gap, we evaluated the effects of cranial irradiation with 10 cGy of 100 MeV/n protons (LET = 0.732 keV/μm) on ATSET performance in male Sprague-Dawley rats. We also investigated whether concurrent exposure to variable gravity (hypergravity step-up, step down, purported to have the same effect as exposure to microgravity (another major spaceflight stressor) exacerbated SR-induced cognitive deficits. Our findings indicate that proton exposure alone significantly impaired ATSET performance, as evidenced by decreased processing speed while performing compound discrimination reversal and extra-dimensional shifting. Notably, no additive or synergistic effects were observed when hypergravity was combined with proton exposure. The impact that low-dose proton exposure has on CNS functionality, particularly in reducing processing speed during complex tasks, warrant further investigation. If similar cognitive deficits were to occur in astronauts exposed to galactic cosmic rays, mission success and safety could be significantly compromised.
