Development Of Human Trophoblast Cell Surface Antigen-2 (Trop-2) Specific Radiopharmaceutical Tracers, Arnav Vipulkumar Patel

ETDs from 2020-2029

Trophoblast cell surface antigen 2 (Trop2) is closely related to the development and progression of triple-negative breast cancers (TNBC) and is also being investigated as a pan-cancer biomarker. Trop-2 tumorigenesis is mediated by the calcium ion signaling pathways. By accurately predicting and targeting Trop-2 for immunotherapy, precision therapy is crucial. Trop-2 is overexpressed in tumor tissues compared to normal tissues, which makes it a promising molecular target for cancer-targeted therapy. This thesis reports the development and preclinical evaluation of two novel Trop-2-specific radiopharmaceutical tracers derived from the clinically approved antibody-drug conjugate Sacituzumab Govitecan (SG): a full antibody drug conjugate-based tracer …

Beyond Neurons: Impact Of Cannabidiol On Glial Cells In Ischemic Stroke, Victória Linden De Rezende, Khiany Mathias, Cinara Ludvig Gonçalves, Rafael Mariano De Bitencourt, Tatiana Barichello, Fabricia Petronilho

Faculty, Staff and Student Publications

Ischemic stroke triggers a complex cascade of events involving inflammation, oxidative stress, and glial cell dysfunction, all of which contribute to neuronal damage and impaired recovery. Glial cells (e.g., astrocytes, microglia, and oligodendrocytes) play key roles in neuroinflammatory responses, making them attractive targets for therapeutic modulation. Cannabidiol, a non-psychoactive phytocannabinoid from Cannabis sativa, exhibits anti-inflammatory, antioxidant, and neuroprotective properties. Preclinical evidence indicates that cannabidiol attenuates glial reactivity, reduces pro-inflammatory signaling, mitigates oxidative stress, and preserves blood-brain and intestinal barrier integrity in stroke models. Moreover, cannabidiol modulates key molecular pathways (e.g., nuclear factor-κB, tumor necrosis factor, and calcium-related signaling), contributing to …

Cabozantinib And Thromboembolism In Patients With Cancer: A Systematic Review, Meta-Analysis, And Retrospective Study, Harish Eswaran, Rohan R Kasthuri, Pavan K Bendapudi, Alok A Khorana, Raj S Kasthuri, Nick Van Es, Steven P Grover

Faculty, Staff and Student Publications

Antiangiogenic agents, including vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors (TKIs), represent an important class of treatments for a range of solid tumors. However, concerns have arisen over potential associations between antiangiogenic agents and thromboembolic events. We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) that compared a frequently used VEGFR TKI, cabozantinib, with placebo or usual care. The primary outcome was the risk of any thromboembolism. Secondary outcomes included the risk of venous thromboembolism (VTE), risk of arterial thromboembolism (ATE) and progression-free survival. 14 RCTs were included with a combined total of 4204 patients, …

Structures Of Invertebrate Pezo-1 Isoforms With A Compact Architecture And A Dispensable Pore-Distal N-Terminal Blade, Briar Bell, Angela M Jaramillo-Granada, Daniel J Orlin, Wei-Hsiang Weng, Haosheng Wen, Marcos Sotomayor, Alexander T Chesler, Matthew L Baker, Julio F Cordero-Morales, Valeria Vásquez

Faculty, Staff and Student Publications

PIEZO channels are mechanosensitive ion channels conserved from plants to humans, yet structures exist for only a few mammalian orthologs. We define the structural and functional diversity of Caenorhabditis elegans PEZO-1, a single gene with extensive alternative splicing, by determining cryo-electron microscopy structures of three representative isoforms: G (full length), K (lacking the pore-distal N-terminal blade), and L (missing most of the blade). PEZO-1G displays mechanically evoked currents yet adopts a compact, semi-flattened conformation that significantly differs from the mammalian domes. The blades exhibit a three-step slope architecture stabilized by inter-blade latching among transmembrane helical units, yielding a circular, steering-wheel-like …

TRPV1, a member of the transient receptor potential vanilloid subfamily, mediates nociception and thermoregulation. TRPV1-targeting analgesics frequently induce hyperthermia, underscoring the need for structural insights to guide the development of safer compounds. Here, we determined the structures of rat TRPV1 bound to the clinical candidate analgesics AMG517, AMG9810, and SB366791. AMG517 and AMG9810 are deeply situated within the S3-S4 interface of the vanilloid pocket, where they interact with residues from the S3-S6 helices, as well as the S4-S5 linker. These interactions induce local deformations in the TRP-box and lower S6 helix, accompanied by a modest rotation of the S1-S4 bundle, …

Differentiation In The Human Urothelia Is Defined By Distinct Alternative Polyadenylation, Ninh B Le, Surbhi Sona, Briana Santo, Yi Zhang, Rosie Ou, R Allen Schweickart, Veena Kochat, William I Padron, Kunal Rai, Shih-Han Lee, Joo Mi Yi, Oliver Wessely, Byron H Lee, Angela H Ting

Faculty, Staff and Student Publications

Distinct epithelial cell states arise during differentiation, but mechanisms generating transcriptomic diversity among them remain poorly defined. The human ureter urothelium contains basal progenitor, intermediate cells, and terminally differentiated umbrella cells. Prior single-cell RNA sequencing revealed similar global gene expression profiles across these states, raising the question of how distinct identities emerge. Here, we show that alternative cleavage and polyadenylation (APA) introduces a major layer of transcriptomic diversity during urothelial differentiation, largely independent of changes in mRNA levels. Analysis of 13,544 urothelial cells identified hundreds of differentiation-associated APA events. Single-cell imaging revealed spatially specific APA patterns, and reporter assays demonstrated …

Mechanistic Insights Into The Antimicrobial Effect Of Benzodioxane-Benzamides Against Escherichia Coli, Lorenzo Suigo, Alessia Lanzini, Valentina Straniero, William Margolin

Faculty, Staff and Student Publications

Background/Objectives: The bacterial cell division machinery is emerging as an attractive target for antimicrobial compounds. FtsZ, a highly conserved essential division protein, is the target for a number of small molecules such as benzamides. Recent studies show that benzodioxane-benzamides (BDOBs) are among the most potent inhibitors of FtsZ function in Gram-positive bacteria, although their ability to inhibit Gram-negative FtsZ, in particular Escherichia coli FtsZ, has been more controversial.

Methods: Here, we use genetic and cytological methods to demonstrate that FtsZ of efflux pump-disabled E. coli can be efficiently targeted by BDOBs.

Results: We show that engineered mutants …

Purpose: Antibody-drug conjugates (ADCs) have transformed the treatment of breast cancer. FDA-approved ADCs such as trastuzumab deruxtecan (T-DXd), sacituzumab govitecan (SG), and datopotamab deruxtecan (Dato-DXd) have demonstrated clinical benefit; however, drug resistance will almost inevitably emerge in the metastatic setting, and there is no established strategy for selecting subsequent ADCs after disease progression to the first exposure to the ADC. This study aimed to define mechanisms of acquired resistance and evaluate rational sequencing approaches.

Experimental design: We generated breast cancer cell lines resistant to T-DXd (TDXd-R) and SG (SG-R). We assessed antigen expression, internalization, and resistance pathways, including efflux transporter …

Triple-negative breast cancer (TNBC) is a prevalent breast cancer subtype with the lowest 5-year survival. Several factors influence outcomes, but their inherent molecular and cellular heterogeneity are increasingly acknowledged as crucial determinants. Here, we report on the spatio-molecular heterogeneity underlying TNBC tumors in a retrospective, treatment-naive cohort with differential prognoses (17 good prognoses [GPx] >15-year survival and 15 poor prognoses [PPx] < 3-year survival]) profiled using GeoMx Digital Spatial Profiler. Analyses reveal that epithelial and microenvironment (TME) states are transcriptionally distinct between groups. Invasive GPx epithelia show an increase in immune transcripts, with a more immune-rich TME (via IF). PPx epithelia, in contrast, are more metabolically and translationally active, with a mesenchymal/fibrotic TME. Pre-cancerous epithelia in PPx exhibit a presence of aggressiveness, marked by increased EMT signaling and complement activity. We identify distinct epithelial gene signatures for PPx and GPx that can accurately classify diagnostic samples and likely inform therapy.

Expression Spectrum Of Te-Driven Transcripts In Human Adult Tissues, Benpeng Miao, Xinlong Luo, Amina Ademovic, Yushan Yang, Tao P Wu, Bo A Zhang

Faculty, Staff and Students Publications

Background

Transposable elements (TEs) are vital components of eukaryotic genomes and have played a critical role in genome evolution. Although most TEs are silenced in the mammalian genome, increasing evidence suggests that certain TEs are actively involved in gene regulation during early developmental stages. However, the extent to which human TEs drive gene transcription in adult tissues remains largely unexplored.

Results

In this study, we systematically analyze 17,329 human transcriptomes to investigate how TEs influence gene transcription across 47 adult tissues. Our findings reveal that TE-driven transcripts are broadly expressed in human tissues, contributing to both housekeeping functions and tissue-specific …

Beyond The Rash: Cutaneous Peripheral T-Cell Lymphoma As A Diagnostic Pitfall In Primary Care, Jared Hensley, Aura Calderon, Blake Martin, Cristina Kochi, Andres Suarez Parraga

School of Medicine Publications

Cutaneous manifestations of T-cell lymphomas may resemble common dermatologic or infectious conditions, increasing the risk of delayed recognition. We report a 78-year-old woman with known peripheral T-cell lymphoma (PTCL) who presented with a rapidly progressive, diffuse erythematous rash accompanied by cervical lymphadenopathy. Initial evaluation prioritized more common etiologies; however, inpatient medicine broadened the differential diagnosis, prompting early hematology and oncology consultation. Contrast-enhanced CT of the neck demonstrated multiple enlarged, partially necrotic left cervical lymph nodes consistent with disease progression. After multidisciplinary discussions and consideration of prognosis, the patient elected palliative-focused management with oncology follow-up. This case underscores the importance of …

Intralabyrinthine Mri Flair As A Predictive Marker For Hearing Loss In Vestibular Schwannomas In Neurofibromatosis Type 2, Robert L. Walker, Maxwell T. Laws, H. Jeffrey Kim, Christopher Zalewski, Ashok Asthagiri, Sruthi Ranganathan, Christina Hayes, John D. Heiss, John A. Butman, Prashant Chittiboina

Department of Radiation Oncology Faculty Papers

BACKGROUND AND OBJECTIVES: The onset of hearing loss due to vestibular schwannomas (VS) is inevitable but does not correlate with the size of the tumor. In patients with Neurofibromatosis Type 2 (NF2) and VS, we previously found an association between pre-contrast fluid-attenuated inversion recovery magnetic resonance imaging (FLAIR MRI) signal in the labyrinth and hearing loss. Here, we asked whether FLAIR hyper-intensity could serve as a predictive biomarker for hearing loss in NF2 patients with VS.

METHODS: A prospective longitudinal study (NCT00598351) of NF2 enrolled 168 subjects between 2008 and 2013. This study included 34 patients with small VS (total …
