Faculty, Staff and Student Publications

Background: Specific microRNAs (miRNAs) were elevated in chronic pancreatitis (CP) patients during islet infusion after total pancreatectomy (TPIAT). We aimed to identify circulating miRNA signatures of pancreatic damage, predict miRNA-mRNA networks to identify potential links to CP pathogenesis and identify islet isolation and transplantation functional outcomes.

Methods: Small RNA sequencing was performed to identify distinct circulating miRNA signatures in CP. Plasma miRNAs were measured using miRCURY LNA SYBR green quantitative real-time polymerase chain reaction assays. Correlation analyses were performed using R software. The miRNA target and disease interactions were determined using miRNet and the miRNA enrichment and annotation tool.

Anchors: A Way For Ftsz Filaments To Stay Membrane Bound, Arindam Naha, Daniel P Haeusser, William Margolin

Faculty, Staff and Student Publications

Most bacteria use the tubulin homolog FtsZ to organize their cell division. FtsZ polymers initially assemble into mobile complexes that circle around a ring-like structure at the cell midpoint, followed by the recruitment of other proteins that will constrict the cytoplasmic membrane and synthesize septal peptidoglycan to divide the cell. Despite the need for FtsZ polymers to associate with the membrane, FtsZ lacks intrinsic membrane binding ability. Consequently, FtsZ polymers have evolved to interact with the membrane through adaptor proteins that both bind FtsZ and the membrane. Here, we discuss recent progress in understanding the functions of these FtsZ membrane …

Innately Expressed Estrogen-Related Receptors In The Skeletal Muscle Are Indispensable For Exercise Fitness, Ashok Kumar, Vihang A Narkar

Faculty, Staff and Student Publications

Peripheral arterial disease (PAD) is a prevalent cardiovascular complication of limb vascular insufficiency, causing ischemic injury, mitochondrial metabolic damage and functional impairment in the skeletal muscle, and ultimately leading to immobility and mortality. While potential therapies have been mostly focussed on revascularization, none of the currently available pharmacological treatments are fully effective in PAD, often leading to amputations, particularly in chronic metabolic diseases. One major limitation of focussed angiogenesis and revascularization as a therapeutic strategy is a limited effect on metabolic restoration and muscle regeneration in the affected limb. Therefore, additional preclinical investigations are needed to discover novel treatment options …

A Machine Learning Approach That Measures Ph Using Acidocest Mri Of Iopamidol, Tianzhe Li, Julio Cárdenas-Rodríguez, Priya N Trakru, Mark D Pagel

Faculty, Staff and Student Publications

Tumor acidosis is an important biomarker for aggressive tumors, and extracellular pH (pHe) of the tumor microenvironment can be used to predict and evaluate tumor responses to chemotherapy and immunotherapy. AcidoCEST MRI measures tumor pHe by exploiting the pH-dependent chemical exchange saturation transfer (CEST) effect of iopamidol, an exogenous CT agent repurposed for CEST MRI. However, all pH fitting methodologies for acidoCEST MRI data have limitations. Herein we present results of the application of machine learning for extracting pH values from CEST Z-spectra of iopamidol. We acquired 36,000 experimental CEST spectra from 200 phantoms of iopamidol prepared at five concentrations, …

Immunotherapy, in the form of hematopoietic stem cell transplantation (HSCT), has been part of the standard of care in the treatment of acute leukemia for over 40 years. Trials evaluating novel immunotherapeutic approaches, such as targeting the programmed death-1 (PD-1) pathway, have unfortunately not yielded comparable results to those seen in solid tumors. Major histocompatibility complex (MHC) proteins are cell surface proteins essential for the adaptive immune system to recognize self versus non-self. MHC typing is used to determine donor compatibility when evaluating patients for HSCT. Recently, loss of MHC class II (MHC II) was shown to be a mechanism …

Cytosolic Dna Accumulation Promotes Breast Cancer Immunogenicity Via A Sting-Independent Pathway, Jing Zhang, Hui Dai, Lei Huo, Jared K Burks, Daniel J Mcgrail

Faculty, Staff and Student Publications

BACKGROUND: Immune checkpoint blockade (ICB) has revolutionized cancer treatment. However, ICB alone has demonstrated only benefit in a small subset of patients with breast cancer. Recent studies have shown that agents targeting DNA damage response improve the efficacy of ICB and promote cytosolic DNA accumulation. However, recent clinical trials have shown that these agents are associated with hematological toxicities. More effective therapeutic strategies are urgently needed.

METHODS: Primary triple negative breast cancer tumors were stained for cytosolic single-stranded DNA (ssDNA) using multiplex immunohistochemical staining. To increase cytosolic ssDNA, we genetically silenced TREX1. The role of tumor cytosolic ssDNA in promoting …

Renal Cell Carcinoma Of Variant Histology: Biology And Therapies, Pavlos Msaouel, Giannicola Genovese, Nizar M Tannir

Faculty, Staff and Student Publications

The term variant histology renal cell carcinomas (vhRCCs), also known as non-clear cell RCCs, refers to a diverse group of malignancies with distinct biologic and therapeutic considerations. The management of vhRCC subtypes is often based on extrapolating results from the more common clear cell RCC studies or basket trials that are not specific to each histology. The unique management of each vhRCC subtype necessitates accurate pathologic diagnosis and dedicated research efforts. Herein, we discuss tailored recommendations for each vhRCC histology informed by ongoing research and clinical experience.

Missense variants throughout ACTA2, encoding smooth muscle α-actin (αSMA), predispose to adult-onset thoracic aortic disease, but variants disrupting arginine 179 (R179) lead to Smooth Muscle Dysfunction Syndrome (SMDS) characterized by diverse childhood-onset vascular diseases. Here we show that αSMA localizes to the nucleus in wildtype (WT) smooth muscle cells (SMCs), enriches in the nucleus with SMC differentiation, and associates with chromatin remodeling complexes and SMC contractile gene promotors. The ACTA2 p.R179 αSMA variant shows decreased nuclear localization. Primary SMCs from Acta2SMC-R179C/+ mice are less differentiated than WT SMCs in vitro and in vivo and have global changes in …

Advances In Vaccine Development For Cancer Prevention And Treatment In Lynch Syndrome, Ana M Bolivar, Fahriye Duzagac, Krishna M Sinha, Eduardo Vilar

Faculty, Staff and Student Publications

Lynch Syndrome (LS) is one of the most common hereditary cancer syndromes, and is caused by mutations in one of the four DNA mismatch repair (MMR) genes, namely MLH1, MSH2, MSH6 and PMS2. Tumors developed by LS carriers display high levels of microsatellite instability, which leads to the accumulation of large numbers of mutations, among which frameshift insertion/deletions (indels) within microsatellite (MS) loci are the most common. As a result, MMR-deficient (MMRd) cells generate increased rates of tumor-specific neoantigens (neoAgs) that can be recognized by the immune system to activate cancer cell killing. In this context, LS is an ideal …

Emerging Therapeutics And Evolving Assessment Criteria For Intracranial Metastases In Patients With Oncogene-Driven Non-Small-Cell Lung Cancer, Kelsey Pan, Kyle Concannon, Jing Li, Jianjun Zhang, John V Heymach

Faculty, Staff and Student Publications

The improved survival outcomes of patients with non-small-cell lung cancer (NSCLC), largely owing to the improved control of systemic disease provided by immune-checkpoint inhibitors and novel targeted therapies, have highlighted the challenges posed by central nervous system (CNS) metastases as a devastating yet common complication, with up to 50% of patients developing such lesions during the course of the disease. Early-generation tyrosine-kinase inhibitors (TKIs) often provide robust systemic disease control in patients with oncogene-driven NSCLCs, although these agents are usually unable to accumulate to therapeutically relevant concentrations in the CNS owing to an inability to cross the blood-brain barrier. However, …

Kunitz-Type Protease Inhibitor Tfpi2 Remodels Stemness And Immunosuppressive Tumor Microenvironment In Glioblastoma, Lizhi Pang, Madeline Dunterman, Songlin Guo, Fatima Khan, Yang Liu, Atousa Bahrami, Wen-Hao Hsu, Craig Horbinski, Charles David James, Peiwen Chen

Faculty, Staff and Student Publications

Glioblastoma (GBM) tumors consist of multiple cell populations, including self-renewing glioblastoma stem cells (GSCs) and immunosuppressive microglia. Here we identified Kunitz-type protease inhibitor TFPI2 as a critical factor connecting these cell populations and their associated GBM hallmarks of stemness and immunosuppression. TFPI2 promotes GSC self-renewal and tumor growth via activation of the c-Jun N-terminal kinase-signal transducer and activator of transcription (STAT)3 pathway. Secreted TFPI2 interacts with its functional receptor CD51 on microglia to trigger the infiltration and immunosuppressive polarization of microglia through activation of STAT6 signaling. Inhibition of the TFPI2-CD51-STAT6 signaling axis activates T cells and synergizes with anti-PD1 therapy …

Co-Targeting Bcl-Xl And Bcl-2 By Protac 753b Eliminates Leukemia Cells And Enhances Efficacy Of Chemotherapy By Targeting Senescent Cells, Yannan Jia, Lina Han, Cassandra L Ramage, Zhe Wang, Connie C Weng, Simona Colla, Weiguo Zhang, Michael Andreeff, Naval Daver, Nitin Jain, Naveen Pemmaraju, Kapil Bhalla, Satu Mustjoki, Peiyi Zhang, Guangrong Zheng, Daohong Zhou, Qi Zhang, Marina Konopleva

Faculty, Staff and Student Publications

BCL-XL and BCL-2 are key anti-apoptotic proteins and validated cancer targets. 753B is a novel BCL-XL/BCL-2 proteolysis targeting chimera (PROTAC) that targets both BCL-XL and BCL-2 to the von Hippel-Lindau (VHL) E3 ligase, leading to BCLX L/BCL-2 ubiquitination and degradation selectively in cells expressing VHL. Because platelets lack VHL expression, 753B spares on-target platelet toxicity caused by the first-generation dual BCL-XL/BCL-2 inhibitor navitoclax (ABT-263). Here, we report pre-clinical single-agent activity of 753B against different leukemia subsets. 753B effectively reduced cell viability and induced dose-dependent degradation of BCL-XL and BCL-2 in a subset of hematopoietic cell lines, acute myeloid leukemia (AML) …

Erythrocyte Ent1-Ampd3 Axis Is An Essential Purinergic Hypoxia Sensor And Energy Regulator Combating Ckd In A Mouse Model, Fang Yu, Xin Zhang, Rodney E Kellems, Angelo D'Alessandro, Yang Xia

Faculty, Staff and Student Publications

Significance statement: Hypoxia drives kidney damage and progression of CKD. Although erythrocytes respond rapidly to hypoxia, their role and the specific molecules sensing and responding to hypoxia in CKD remain unclear. In this study, we demonstrated in a mouse model that erythrocyte ENT1-AMPD3 is a master energy regulator of the intracellular purinergic hypoxic compensatory response that promotes rapid energy supply from extracellular adenosine, eAMPK-dependent metabolic reprogramming, and O 2 delivery, which combat renal hypoxia and progression of CKD. ENT1-AMPD3-AMPK-BPGM comprise a group of circulating erythroid-specific biomarkers, providing early diagnostic and novel therapeutic targets for CKD.

Background: Hypoxia drives kidney damage …

The mesencephalic locomotor region (MLR) is a brain stem area whose stimulation triggers graded forward locomotion. How MLR neurons recruit downstream vsx2+ (V2a) reticulospinal neurons (RSNs) is poorly understood. Here, to overcome this challenge, we uncovered the locus of MLR in transparent larval zebrafish and show that the MLR locus is distinct from the nucleus of the medial longitudinal fasciculus. MLR stimulations reliably elicit forward locomotion of controlled duration and frequency. MLR neurons recruit V2a RSNs via projections onto somata in pontine and retropontine areas, and onto dendrites in the medulla. High-speed volumetric imaging of neuronal activity reveals that …

Elementary Teachers’ Perception Of Digital Resources Based On Student Achievement, Tanya R. Small

Doctor of Education (Ed.D)

Many factors impact teachers’ decisions about when and how to implement technology during instruction. However, a gap exists in understanding teachers’ motivations for technology integration and face-to-face instruction. Therefore, this qualitative case study explored how teachers’ perceptions of student achievement, motivation, classroom behaviors, and digital challenges influenced their decisions about using technology or direct instruction in the classroom setting. A group of 20 teachers from two southern Florida public elementary schools completed anonymous Likert-scale surveys; six teachers participated in semi-structured interviews. The findings determined via descriptive statistics and thematic analysis revealed that teachers’ inclusion of technology and traditional resources is …

A Pancreatic Player In Dementia: Pathological Role For Islet Amyloid Polypeptide Accumulation In The Brain

Faculty, Staff and Students Publications

Type 2 diabetes mellitus patients have a markedly higher risk of developing dementia. While multiple factors contribute to this predisposition, one of these involves the increased secretion of amylin, or islet amyloid polypeptide, that accompanies the pathophysiology of type 2 diabetes mellitus. Islet amyloid polypeptide accumulation has undoubtedly been implicated in various forms of dementia, including Alzheimer’s disease and vascular dementia, but the exact mechanisms underlying islet amyloid polypeptide’s causative role in dementia are unclear. In this review, we have summarized the literature supporting the various mechanisms by which islet amyloid polypeptide accumulation may cause neuronal damage, ultimately leading to …

Faculty, Staff and Students Publications

Aging is a complex biological process that is characterized by low-grade inflammation, called inflammaging. Aging affects multiple organs including eye and lacrimal gland. Tumor necrosis factor (TNF) is a pleiotropic cytokine that participates in inflammation, activation of proteases such as cathepsin S, and formation of ectopic lymphoid organs. Using genetic and pharmacological approaches, we investigated the role of TNF in age-related dry eye disease, emphasizing the ocular surface and lacrimal gland inflammation. Our results show the increased protein and mRNA levels of TNF in aged lacrimal glands, accompanied by increased TNF, IL1β, IL-18, CCL5, CXCL1, IL-2, IL-2 receptor alpha (CD25), …

Faculty, Staff and Students Publications

BACKGROUND & AIMS: Metabolic biomarkers with pathophysiological relevance is lacking in pediatric diabetes. We aimed to identify novel metabolic biomarkers in pediatric type 1 (T1D) and type 2 diabetes (T2D). We hypothesized that (1) targeted plasma metabolomics, focused on plasma amino acid concentrations, could identify distinctively altered patterns in children with T1D or T2D, and (2) there are specific changes in concentrations of metabolites related to branch chain amino acids (BCAA) and arginine metabolism in children with T2D.

METHODS: In a pilot study, we enrolled children with T1D (n = 15) and T2D (n = 13), and healthy controls (n …

Immune correlates of hepatitis C virus (HCV) clearance and control remain poorly defined due to the lack of an informative animal model. We recently described acute and chronic rodent HCV-like virus (RHV) infections in lab mice. Here, we developed MHC class I and class II tetramers to characterize the serial changes in RHV-specific CD8 and CD4 T cells during acute and chronic infection in C57BL/6J mice. RHV infection induced rapid expansion of T cells targeting viral structural and nonstructural proteins. After virus clearance, the virus-specific T cells transitioned from effectors to long-lived liver-resident memory T cells (TRM). The effector and …

Patients harboring CRLF2-rearranged B-lineage acute lymphocytic leukemia (B-ALL) face a 5-year survival rate as low as 20%. While significant gains have been made to position targeted therapies for B-ALL treatment, continued efforts are needed to develop therapeutic options with improved duration of response. Here, first we have demonstrated that patients with CRLF2-rearranged Ph-like ALL harbor elevated thymic stromal lymphopoietin receptor (TSLPR) expression, which is comparable with CD19. Then we present and evaluate the anti-tumor characteristics of 1B7/CD3, a novel CD3-redirecting bispecific antibody (BsAb) that co-targets TSLPR. In vitro, 1B7/CD3 exhibits optimal binding to both human and cynomolgus CD3 and TSLPR. …
