In Vivo Antibody Labeling Route And Fluorophore Dictate Labeling Efficiency, Sensitivity, And Longevity, Natalie B Hagan, Charles Inaku, Nikesh Kunder, Tayleur White, Thierry Iraguha, Anna Meyer, Kristen E Pauken, Jason M Schenkel

Faculty, Staff and Student Publications

Leukocytes migrate through the blood and extravasate into organs to surveil the host for infection or cancer. Recently, we demonstrated that intravenous (IV) anti-CD45.2 antibody labeling allowed for precise tracking of leukocyte migration. However, the narrow labeling window can make this approach challenging for tracking rare migration events. Here, we show that altering antibody administration route and fluorophore can significantly extend the antibody active labeling time. We found that while both IV and intraperitoneal (IP) anti-CD45.2 antibody labeled circulating leukocytes after injection, they had different kinetic properties that impacted labeling time and intensity. Quantification of circulating antibody revealed that while …

Hypertriglyceridemia (HTG), particularly in combined hyperlipidemia, increases risk for atherosclerotic cardiovascular disease, but the underlying mechanisms remain incompletely understood. We sought to determine contributions of circulating monocytes to atherosclerosis associated with HTG in combined hyperlipidemia, created by transgenic expression of human apoCIII in Ldlr−/− mice (Ldlr−/−ApoCIIItg) fed Western high-fat diet (WD). Tissue culture with THP-1 and primary human monocytes was used to examine effects of triglyceride (TG)-rich lipoproteins on monocytes. Ldlr−/−ApoCIIItg mice were also treated with apoCIII antisense oligonucleotide (ASO) and examined for foamy monocytes and atherosclerosis. Compared to Ldlr−/− mice, Ldlr−/−ApoCIIItg mice fed …

Effects Of Smoking Behavior On Lung Metastasis In The All Of Us Research Program, Vikram R Shaw, Jinyoung Byun, Younghun Han, Christopher I Amos

Faculty, Staff and Students Publications

Smoking may be associated with an increased risk of lung metastasis in cancers of non-lung origin. We leverage survey and electronic health record data from the diverse All of Us Research Program (AoURP) database to investigate whether smoking and smoking-related behaviors increase the risk of lung metastasis in non-lung primary cancers. The results suggest that cigarette use, measured by four continuous variables, does not increase the risk of lung metastasis in seven common cancer types but demonstrates a small significant effect in a cohort including all types of cancer in the database in both univariable and multivariable analyses. An increased …

Abnormal adipogenesis is a major contributor to fetal growth restriction (FGR) and its associated complications. However, the underlying etiology remains unclear. Here, it is reported that the placentas of women with pregnancies complicated with FGR exhibit peroxisome proliferator-activated receptor γ (PPARγ) inactivation. In mice, trophoblast-specific ablation of murine PPARγ reproduces the phenotype of human fetuses with FGR and defective adipogenesis. Coculture of trophoblasts with preadipocytes significantly improves preadipocyte commitment and differentiation and increases the transcription of a series of adipogenic genes via intercellular transfer of exosomal PPARγ proteins. Moreover, nanoparticle-mediated placenta-specific delivery of rosiglitazone (RGZ) significantly rescues adipogenesis defects in …

Idiopathic pulmonary fibrosis (IPF) is a disease with a poor prognosis and no curative therapies. Fibroblast activation by transforming growth factor β1 (TGFβ1) and disrupted metabolic pathways, including the arginine-polyamine pathway, play crucial roles in IPF development. Polyamines are agonists of the calcium/cation-sensing receptor (CaSR), activation of which is detrimental for asthma and pulmonary hypertension, but its role in IPF is unknown. To address this question, we evaluated polyamine abundance using metabolomic analysis of IPF patient saliva. Furthermore, we examined CaSR functional expression in human lung fibroblasts (HLFs), assessed the anti-fibrotic effects of a CaSR antagonist, NPS2143, in TGFβ1-activated normal …

Lesion Classification By Model-Based Feature Extraction: A Differential Affine Invariant Model Of Soft Tissue Elasticity In Ct Images, Weiguo Cao, Marc J Pomeroy, Zhengrong Liang, Yongfeng Gao, Yongyi Shi, Jiaxing Tan, Fangfang Han, Jing Wang, Jianhua Ma, Hongbin Lu, Almas F Abbasi, Perry J Pickhardt

Faculty, Staff and Student Publications

The elasticity of soft tissues has been widely considered a characteristic property for differentiation of healthy and lesions and, therefore, motivated the development of several elasticity imaging modalities, for example, ultrasound elastography, magnetic resonance elastography, and optical coherence elastography to directly measure the tissue elasticity. This paper proposes an alternative approach of modeling the elasticity for prior knowledge-based extraction of tissue elastic characteristic features for machine learning (ML) lesion classification using computed tomography (CT) imaging modality. The model describes a dynamic non-rigid (or elastic) soft tissue deformation in differential manifold to mimic the tissues’ elasticity under wave fluctuation in vivo. …

Faculty, Staff and Student Publications

Background: The relationship between vitamin D and prostate cancer has primarily been characterized among White men. Black men, however, have higher prostate cancer incidence and mortality rates, chronically low circulating vitamin D levels, and ancestry-specific genetic variants in vitamin D-related genes. Here, we examine critical genes in the vitamin D pathway and prostate cancer risk in Black men.

Methods: We assessed a total of 73 candidate variants in genes (namely GC, CYP27A1, CYP27B1, CYP24A1, VDR, and RXRA) including functional variants previously associated with prostate cancer and circulating 25(OHD) in White men. Associations with prostate cancer risk were examined using genome-wide …

Tandem duplications (TDs) in exons of upstream binding transcription factor (UBTF-TD) are a rare recurrent alteration in pediatric and adult acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS)/neoplasm. Although recently identified, AML with UBTF-TD is now considered a distinct subtype of AML. To further our understanding of myeloid neoplasms with UBTF-TD, we analyzed clinical, morphologic, and immunophenotypic characteristics of 27 pediatric patients with UBTF-TD-positive myeloid neoplasm, including 21 diagnosed as AML and 6 as MDS. Our data demonstrated that UBTF-TD is frequently associated with cytopenia, hypercellular marrow with erythroid hyperplasia, and trilineage dysplasia. Blasts …

Introduction: Drug resistance remains a major clinical challenge in EGFR-mutant NSCLC tumors owing to pathway reactivation, pathway bypass, and pathway indifference resistance mechanisms to evade tyrosine kinase inhibitor (TKI) suppression. Fusion of receptor tyrosine kinases (RTKs), such as RET, ALK, and FGFR3, has been reported to mediate EGFR TKI resistance. Given the rarity of these fusions and the heterogeneous nature of the condition, no prospective clinical trials evaluated the incidence, safety, and therapeutic benefit of dual EGFR-RTK inhibition.

Methods: We queried clinical databases from multiple institutions to identify patients who had RTK fusions detected on next-generation sequencing testing results from …

Age-Associated Proteins Explain The Role Of Medial Temporal Lobe Networks In Alzheimer’S Disease, Adam Turnbull, Yejin Kim, Kai Zhang, Xiaoqian Jiang, Zihuai He, Victor W Henderson, F Vankee Lin

Faculty, Staff and Student Publications

The structural connectivity (SC) of the medial temporal lobe and its associated cortical anterior temporal and posterior medial networks (MTL-AT-PM) is linked to pathologies and memory decline in Alzheimer's disease (AD). However, neuroimaging analyses cannot tell us how SC changes occur in AD at the molecular level and do not provide a means of intervening to slow/prevent pathology-related changes in MTL-AT-PM SC. The current study aimed to understand how and where AD-related changes occur within MTL-AT-PM using proteomics. We used a 4-step approach in 101 older adults from a local sample, aiming to understand how proteins and SC in combination …

Manual Therapy For Fibrosis-Related Late Effect Dysphagia In Head And Neck Cancer Survivors: The Mantle Nonrandomized Clinical Trial, Holly Mcmillan, Carla L Warneke, Sheila Buoy, Christine Porsche, Kiara Savage, Stephen Y Lai, Clifton D Fuller, Katherine A Hutcheson

Faculty, Staff and Student Publications

Importance: Late radiation-associated dysphagia (RAD) after head and neck cancer (HNC) treatment is challenging and commonly treatment refractory, with fibrosis stiffening connective tissues and compressing peripheral nerve tracts, contributing to diminished strength and possibly denervation of swallowing muscles. Manual therapy (MT), while common for cancer-related pain and other indications, remains largely unstudied for fibrosis-related late RAD.

Objective: To determine the feasibility and safety of MT, estimate effect size and durability of MT for associated improvements in cervical range of motion (CROM), and examine functional outcomes after MT in survivors of HNC with fibrosis-related late RAD.

Design, setting, and participants: This …

Like all organs, the thymus grows in size and function rapidly during development, but this growth comes to a halt after birth. However, the molecular mechanisms behind such a transition in the thymus remain obscure. Using single-cell RNA sequencing (scRNA-seq) of the murine thymic stroma, we identified that major transcriptomic changes occur in the endothelium and mesenchyme across the transition to homeostasis. Differentially expressed gene and intercellular network analyses of temporally resolved scRNA-seq data revealed fibroblast-derived insulin-like growth factor 2 (IGF2) as a candidate driving neonatal thymic expansion. We demonstrated that IGF2 activity promotes a cortical thymic epithelial cell-specific proliferation …

Tumours of the appendix — a vestigial digestive organ attached to the colon — are rare. Although we estimate that around 3,000 new appendiceal cancer cases are diagnosed annually in the USA, the challenges of accurately diagnosing and identifying this tumour type suggest that this number may underestimate true population incidence. In the current absence of disease-specific screening and diagnostic imaging modalities, or well-established risk factors, the incidental discovery of appendix tumours is often prompted by acute presentations mimicking appendicitis or when the tumour has already spread into the abdominal cavity — wherein the potential misclassification of appendiceal tumours as …
