PURPOSE: Recent evidence supports incorporating 18 F-Fluciclovine PET for glioblastoma treatment planning and monitoring, as it better captures tumor infiltration compared to conventional MRI. However, the relationship between PET- and MRI-defined tumor volumes remains unclear, particularly in the post-treatment setting. This study prospectively compares tumor volumes on MRI and PET at multiple timepoints throughout the treatment course and evaluates volumetric changes with therapy.

METHODS: We prospectively enrolled 8 adults with IDH-wildtype glioblastoma treated with surgery and chemoradiation between September 2019 and 2021. Participants underwent paired 18 F-Fluciclovine PET/CT and conventional MRI at four timepoints: preoperatively, pre-radiation, and at one- and …

Acute Kidney Injury Is Associated With Elevated Urinary Endotrophin, Amanda J Clark, Brenda Mendoza Flores, Marie Christelle Saade, Kyle Q Vu, Isaac J Pence, Ningyan Zhang, Zhiqiang An, Dawei Bu, Philipp E Scherer, Samir M Parikh

Faculty, Staff and Student Publications

Acute kidney injury (AKI) is prevalent among hospitalized patients. Novel biomarkers are needed to diagnose AKI and target therapies. Endotrophin (ETP) is a molecule released during collagen type VI formation that may promote injury and fibrosis. Although serum ETP elevation has been associated with adverse outcomes in AKI, urinary ETP has not been assessed in AKI, nor has ETP been evaluated in a pediatric population. Urine samples were collected from a tertiary children's hospital. Medical records were reviewed, and patients who met criteria were sorted into three categories:

Delayed Presentation Of A Retained Colonic Segment In A Child With Intestinal Failure On Teduglutide, Rachel C Bordelon, Sarah J Varalla, Varaha S Tammisetti, Mohamed M Shahin, Amanda Tchakarov, Essam Imseis, Allison L Speer

Faculty, Staff and Student Publications

Teduglutide is a glucagon-like peptide 2 (GLP-2) analogue that was approved by the United States Food and Drug Administration for the treatment of pediatric (>1 year) intestinal failure due to short bowel syndrome in 2019. GLP-2 analogues promote rapid intestinal adaptation, increasing the absorptive capacity of residual intestine after surgical resection to aid the achievement of enteral autonomy or reduce parenteral nutrition requirements. Despite relatively few reported side effects, there is a theoretical risk of proliferative complications. Here we present an intriguing case of a pediatric patient found to have a decade-long retained, discontinuous segment of colon from a …

Restricting Metabolic Plasticity Enhances Stress Adaptation Through The Modulation Of Pdh And Hif1a In Trap1-Depleted Colon Cancer, Hong-Yuan Tsai, Miao-Hsueh Chen, Jihye Yun, Lisa A Lai, John F Valentine, Mary P Bronner, Teresa A Brentnall, Sheng Pan, Ru Chen

Faculty, Staff and Student Publications

Metabolic plasticity allows cancer cells to survive under adverse conditions. To investigate the role of mitochondrial chaperone tumor necrosis factor receptor-associated protein 1 (TRAP1) in this process, we used CRISPR/Cas9 mediated genetic deletion to knock out (KO) TRAP1 in colon cancer cells. Depletion of TRAP1 triggered a series of events: induced metabolic reprogramming, increased glycolytic flux, downregulation of mitochondrial complex I, and elevated ROS generation. TRAP1-deficient cells showed tolerance to Oxidative Phosphorylation (OXPHOS) inhibitors and exhibited a higher extracellular acidification rate (ECAR). Additionally, TRAP1 depletion activated hypoxia response elements (HREs) and upregulated HIF1A target genes such as GLUT1 and MCT1. …

Previous studies have suggested that alterations in white matter (WM) microstructure are implicated in suicidal thoughts and behaviours (STBs). However, findings of diffusion tensor imaging (DTI) studies have been inconsistent. In this large-scale mega-analysis conducted by the ENIGMA Suicidal Thoughts and Behaviours (ENIGMA-STB) consortium, we examined WM alterations associated with STBs. Data processing was standardised across sites, and resulting WM microstructure measures (fractional anisotropy (FA), axial diffusivity (AD), mean diffusivity and radial diffusivity) for 24 WM tracts and one global measure were pooled across 40 cohorts. We compared these measures among individuals with a psychiatric diagnosis and lifetime history of …

Leptin, a hormone primarily secreted by adipocytes, regulates energy balance and systemic metabolism through its interaction with the leptin receptor (LEPR). Beyond these functions, leptin signaling has been implicated in the pathogenesis of tissue fibrosis. Here, we report the x-ray crystal structures of a leptin-neutralizing antibody (hLep3) in the unbound and leptin-bound states. The interaction of this antibody with leptin mimics the interaction of the LEPR with leptin, providing direct insights into the mechanism by which the antibody disrupts leptin signaling. We furthermore evaluate the therapeutic potential of neutralizing leptin with this antibody across distinct mouse models of fibrosis affecting …

Hemorrhage is the leading cause of preventable death on the battlefield, yet combat medics lack clinical decision support systems to help stratify hemorrhage risk in trauma casualties. We previously trained the Automated Processing of the Physiological Registry for Assessment of Injury Severity - Hemorrhage Risk Index (APPRAISE-HRI) software to associate patterns in vital signs (heart rate and blood pressure) collected from trauma patients with three HRI levels: I (low), II (average), or III (high). To independently validate APPRAISE-HRI and obtain U.S. Food and Drug Administration (FDA) clearance, we collected trauma registry and continuous vital sign data from 5895 trauma patients …

When operating on gliomas near critical language regions, surgeons risk either leaving residual tumor or inducing permanent postoperative language deficits (PLDs). Despite the advent of intraoperative mapping techniques, subjective judgments frequently determine important surgical decisions. We aim to inform data-driven surgery by constructing a non-invasive mapping approach that quantitatively predicts the impact of individual surgical decisions on long-term language function. This study included 79 consecutive patients undergoing resection of language-eloquent gliomas. Patients underwent preoperative navigated transcranial magnetic stimulation (TMS) language mapping to identify language-positive sites ("TMS points") and their associated white matter tracts ("TMS tracts") as well as formal language …

Faculty, Staff and Student Publications

Background: Osteosarcoma (OS) lung metastases remain a significant therapeutic challenge. Innate immune activation is a promising therapeutic approach. Innate immune agonists can modulate the tumor immune microenvironment and improve therapeutic response.

Methods: Using an experimental syngeneic OS lung metastasis BALB/c mouse model with K7M3-luc OS cells, we evaluated the antitumor effects of yeast-derived particulate β-glucan in prevention and therapeutic settings. We then assessed whether the CD40 agonist (CD40a) in combination with β-glucan increased therapeutic response in two different immune-competent mouse models of OS lung tumor burden.

Results: In the pretreatment settings, mice treated with β-glucan prior to OS cell infusion …

The Role Of Traumatic Brain Injury On Intimate Partner Violence And Changes In Mental Health From Late Adolescence To Young Adulthood, Eric J Connolly, Elizabeth Baumler, Deborah M Little, Meghan L Royle, Anne C Wingert, Leila Wood, Jeff R Temple

Faculty, Staff and Student Publications

Purpose: Intimate partner violence (IPV) victimization and traumatic brain injury (TBI) are common correlates of mental health problems in adolescence. However, research has yet to investigate whether IPV victimization is related to developmental changes in mental health, as well as the contributing role that TBI may play in conditioning this association. We address this gap by analyzing longitudinal data with well-validated measures of mental health from an ethnically diverse sample of adolescents.

Methods: Prospective data from the Dating it Safe sample (n = 699) were used to measure IPV victimization, depression, post-traumatic stress, binge drinking, and TBI from 2015 to …

The persistent residual tumor cells that survive after chemotherapy are a major cause of treatment failure, but their survival mechanisms remain largely elusive. These cancer cells are typically characterized by a quiescent state with suppressed activity of MYC and MTOR. We observed that the MYC-suppressed persistent triple-negative breast cancer (TNBC) cells are metabolically flexible and can upregulate mitochondrial oxidative phosphorylation (OXPHOS) genes and respiratory function ("OXPHOS-high" cell state) in response to DNA-damaging anthracyclines such as doxorubicin, but not to taxanes. The elevated biomass and respiratory function of mitochondria in OXPHOS-high persistent cancer cells were associated with mitochondrial elongation and remodeling, …

Histone post-translational modifications (PTMs) are crucial to eukaryotic genome regulation, with a range of reported functions and mechanisms of action. Though often studied individually, it has long been recognized that the modifications function by combinatorial synergy or antagonism. Interplay may involve PTMs on the same histone, within the same nucleosome (containing a histone octamer), or between nucleosomes in higher-order chromatin. Given this, the field must distinguish ever greater complexity, and the context in which it is studied, with brevity and precision. The proteoform was introduced to define individual forms of a protein by sequence and PTMs, followed by the nucleoform …
