Clonal hematopoiesis (CH) is detectable in upwards of 20% of patients with solid tumors and is associated with worsened prognosis; however, its role in tumor immunology and immune checkpoint therapy (ICT) is unknown. Using a bone marrow chimera model of Tet2+/mut CH in mice with solid tumors, we found the Tet2-mutant myeloid cells are abundant in the tumor microenvironment and contributed to an improved response to ICT. Mechanistically, Tet2+/mut macrophages inside the tumor act as immunogenic antigen-presenting cells that more effectively cross-prime naive CD8+ T cells in response to IFNγ. In human cohorts of 35,971 non-small cell lung cancer patients …

Faculty, Staff and Student Publications
Background/objectives: Progression of pancreatic ductal adenocarcinoma (PDAC) and other carcinomas relies on cancer-associated fibroblasts (CAFs). A subset of CAFs is derived from adipose stromal cells (ASCs) recruited by tumors and the ASC-CAF conversion has been associated with invasiveness and poor prognosis.
Methods: To explore the underlying molecular mechanisms, we used a model based on primary ASCs derived from human visceral adipose tissue co-cultured with human PDAC cell line Capan-1. To investigate cancer progression in vivo, we also used mice orthotopically grafted with mouse KPC cells.
Results: Genomic analysis revealed that Capan-1 co-culture induces Wnt and TGFβ signaling and extracellular matrix …

Introduction: Hepatocellular carcinoma (HCC) can develop in individuals with metabolic dysfunction-associated steatotic liver disease (MASLD) without cirrhosis, especially in those with elevated liver enzymes. However, there is currently no low-cost, scalable screening tool for this population. To address this need, we investigated the association between serial changes in FIB-4 (fibrosis-4) scores over a 3-year period and the risk of developing HCC in a large, diverse cohort of patients with MASLD without cirrhosis.
Methods: This study utilized a nationwide cohort from the National Health Insurance Research Database (NHIRD), including 810,698 patients with MASLD who had demographic and laboratory data at baseline …

Investigating Age-Related Decline In Sensorimotor Control Using Robotic Tasks, Laura Alvarez-Hidalgo, Ellie Edlmann, Gunnar Schmidtmann, Ian S. Howard
School of Health Professions
Aging is associated with changes in sensorimotor control that contribute to functional decline, mobility limitations, and increased fall risk. Traditional motor assessments often rely on subjective measures, highlighting the need for objective, quantitative tools. We developed three robot-based tasks using the vBOT planar manipulandum to evaluate sensorimotor performance in healthy young (<35 years) and older (>60 years) adults. These tasks uniquely combined bimanual control and altered dynamic conditions to assess age-related differences. The first task required bimanual coordination to control a virtual 2D arm over 400 center-out and return trials, targeting de novo motor learning. The second task involved unimanual reaching with the …35>

Individuals with history of chemo- or radiotherapy frequently exhibit somatic mosaicism in the blood, often involving mutations in genes responsible for DNA damage responses (DDR), such as CHEK2. However, the mechanisms by which CHEK2 mutations promote the expansion of mutant cells following chemo- or radiotherapy remain poorly understood. Here, we demonstrate that loss of CHEK2 confers resistance to chemotherapy in hematopoietic stem and progenitor cells (HSPCs). Through a CRISPR-based screen, we identified CHEK2 as a gene whose loss enhances resistance to cytotoxic chemotherapies. A complementary drug screen revealed that CHEK2-mutant cells are also resistant to DNA hypomethylating agents. Chek2-deficient HSPCs …

Heterozygosity at human leukocyte antigen (HLA) loci may improve lung cancer immunosurveillance by increasing recognition of the tumor by the immune system. Previous studies utilizing data from population-level biobanks, such as the United Kingdom Biobank and FinnGen, have identified an association between germline HLA class-II heterozygosity and reduced lung cancer risk in smokers. In the present study, we evaluate the association between HLA heterozygosity and lung cancer in a large case-control study (15,302 cases; 14,580 controls) with imputed HLA allele-type information, comparing differences in HLA heterozygosity between smokers and non-smokers, amongst lung cancer subtypes, and at 2- and 4-digit HLA …
Assessing Localized Recovery And Synchrony Of An Endangered Wetland Species., Aiyana Reissman
Assessing Localized Recovery And Synchrony Of An Endangered Wetland Species., Aiyana Reissman
Theses
The state and federally endangered light-footed Ridgway’s rail (LFRR; Rallus obsoletus levipes) is central to regional conservation, yet the drivers of its population fluctuations remain poorly understood. The fragmented nature of coastal wetlands in Southern California is threatening the existence of endemic species like the LFRR. Tidal inundation, severe storms, and overpredation threaten the survival of LFRR. This study addresses population fluctuations by analyzing the spatial and temporal drivers of LFRR populations to inform effective, site-specific management.
To do this, a 45-year (1980–2024) LFRR census data set across 16 wetlands throughout its range in California was synthesized. A multi-faceted …

BACKGROUND: Parkinson's disease (PD) is the second most common neurodegenerative disease, characterized by both motor and non-motor symptoms. Falls and fractures are common in advanced PD but the risk of fractures in newly diagnosed people with PD and the impact of treatment with levodopa is understudied.
METHODS: We investigated the risk of fractures among Medicare beneficiaries with incident PD age ≥ 67 compared to controls. Among PD cases only with continuous Part D medication coverage, we examined the effect of levodopa treatment on fracture risk. We identified incident PD cases (N = 68,150) within a population-based sample of 2017 Medicare …

Introduction Social prescribing is an approach to addressing non-medical issues affecting people’s health and well-being (eg, loneliness, housing or financial problems). It has gained international traction over recent years as complementary to medical care. A larger research project, comparing social prescribing across European countries, is considering how to tailor provision for the following groups: (a) LGBTIQ+persons, (b) refugees and first-generation immigrants and (c) older adults living alone. As part of this research, a qualitative study will address the question: What are the enabling and limiting factors associated with implementing social prescribing, across different European countries, from the perspective of key …
The Phyrfly Opus: A Unified Standard For Hyperdimensional Time Vectors, Spectrally Isolated Coordination, Neural Hierarchies, And Distributed Proprioception, Steven Kirkland
Defensive Publications Series
This monograph establishes 264 prior art claims for a decentralized, connectionless timing and positioning architecture comprising the UTLP, RFIP, and SMSP protocol triad. It formalizes the PHYRFLY nomenclature to distinguish low-level, hardware-scheduled Physical-Layer synchronization primitives from higher-level application orchestration. The core novelty centers on a Vector Time Representation, encoding temporal state as 8 phase values (ticks modulo coprime integers 211–251) transmitted in 8 bytes, then expanded locally into ~10,000-dimensional hyperdimensional chord vectors for similarity computation and drift estimation. This cyclic encoding enables automatic phase-lock convergence within 5–10 beacon exchanges regardless of initial offset, with the Chinese Remainder Theorem guaranteeing unique …

Rucking has gained in popularity over the past several years due to accessibility, affordability, functionality, and wide-ranging health benefits. Despite its popularity, there are several unknown biomechanical and physiological areas that remain underexplored. PURPOSE: Investigate the effects varying loads and inclines have on biomechanical and physiological factors. METHODS: Fifteen recreationally active individuals were randomly assigned to six different conditions on the treadmill. Treadmill conditions consisted of being unweighted or wearing a weighted pack while walking 1.5 m/s inclined (4.5 degrees), declined (-4.5), or flat. The weight of the ruck was relative to the participant's mass and heart rate (HR) in …

Sleep restriction (SR) impairs glycemic control, elevating the postprandial blood glucose (BG) response, an independent predictor of morbidity and mortality. Stair stepping and peripheral heating with negative pressure have been shown to acutely improve glycemic indices but have not been tested after SR. PURPOSE: To examine if stair stepping or peripheral heating with negative pressure improve postprandial BG after SR. We hypothesized 1-minute of brief, low-effort stair stepping and 60 min peripheral heating with negative pressure would improve postprandial glucose in sleep restricted (≤4 hours) young adults. METHODS: Participants (N=24; 22 (2) y; 13 female; 23.8 (5) kg/m2) performed a …

The quality of mitochondrial function is an essential part of cellular health. However, mutations occur within the cell during the metabolic processes of replication, repair, respiration and turnover. A build up of these mutations can cause mitochondrial dysfunction, which in turn leads to cell, tissue and eventually organismal dysfunction. Disease such as sarcopenia and cardiovascular disease are prime examples of the results of this process. Thus, better understanding mitochondrial DNA (mtDNA) turnover rates could contribute to a decreased risk of disease. PURPOSE: The purpose of this study was to 1) outline a procedure to isolate pure mtDNA from frozen …

Cold-water immersion (CWI) has increased in popularity – both as a recovery intervention after exercise and for possible chronic health benefits. In addition, a single CWI session evokes physiological responses that can be powerful tools to demonstrate core concepts of cardiorespiratory physiology. PURPOSE: The purpose of this study was to characterize the physiological responses to CWI and either light exercise or rest immediately afterwards. METHODS: Eight participants (29.4 ± 8.2 years old) were recruited from a graduate-level kinesiology course and paired based on sex (six men & two women) and body size (72.9 ± 11.2 kg). All participants …

Muscle contractions help regulate blood glucose by promoting uptake in the muscle cells. However, modern sedentary (low activity level) lifestyles significantly reduce opportunities for muscle contractions. PURPOSE: This study examined whether brief full-body muscle contractions could effectively alter glucose regulation with responses differing by activity level. METHODS: Three High-Active individuals (HA; 3100 ± 1002 MET-minute/week, 24 ± 5.7 years, 1 woman) and 3 Low-Active individuals (LA;129 ± 152 MET-minute/week, 19 ± 1.4 years, 1 woman) performed randomized and counterbalanced tasks involving brief full-body muscle contraction and non-contraction tasks. The contraction task consisted of 3 sets of 15s fully-body …

Visceral adipose tissue (VAT) is strongly associated with metabolic disease risk; however, commonly used anthropometric measures, such as body mass index (BMI), waist circumference (WC), and percentage of body fat (%BF), may not accurately estimate VAT. The Body Roundness Index (BRI) is an anthropometric index that combines height and WC and relies on geometry and other statistically generated nonlinear models with the intent of estimating VAT. PURPOSE: As such, this study aimed to determine if the BRI is more highly correlated with VAT compared to BMI, WC, or %BF. METHODS: Height, weight, BMI, %BF, and visceral fat area …

Susceptibility To Eccentric Contractions-Induced Locomotor Muscle Injury In Cigarette Smoke-Exposed Mice, David Tran, Leonardo Nogueira
International Journal of Exercise Science: Conference Proceedings
Chronic exposure to tobacco cigarette smoke (CS) leads to pulmonary damage, inflammation, exercise intolerance, and skeletal muscle contractile and repair dysfunction, as our group has shown that CS exposure also delays muscle repair after eccentric contractions. This study investigated whether chronic CS exposure increases the susceptibility of locomotor muscles to injury from a session of eccentric contractions, as previous studies have shown that smokers have a greater risk of muscle injuries. Methods: Young adult (8 weeks old) wild-type mice (C57BL/6J, IACUC 25-071, n=24) were exposed to daily periods of CS or air (as controls) for eight consecutive weeks. After the …
