Faculty, Staff and Student Publications

Acute myeloid leukemia (AML) is a hematologic malignancy with a poor prognosis, often presenting with systemic and extramedullary manifestations. Leukemia cutis (LC), the infiltration of leukemic cells into the skin, is a rare and clinically significant complication of AML. It often signals extramedullary disease involvement, may precede systemic relapse, and is associated with poor survival outcomes. We report the case of a 36-year-old female with AML who developed recurrent, reddish-brown nodular skin lesions on the face, trunk, and extremities, consistent with LC. Despite achieving initial remission with induction and consolidation chemotherapy, she experienced early LC recurrence, pancytopenia, hepatobiliary dysfunction, and …

Clinical Use Of Gafchromic Ebt4 Film For In Vivo Dosimetry For Total Body Irradiation, Emily Draeger, Fada Guan, Min-Young Lee, Dae Yup Han, William Donahue, Zhe Jay Chen

Faculty, Staff and Student Publications

Purpose: In vivo dosimetry is a common requirement to validate dose accuracy/uniformity in total body irradiation (TBI). Several detectors can be used for in vivo dosimetry, including thermoluminescent dosimeters (TLDs), diodes, ion chambers, optically stimulated luminescent dosimeters (OSLDs), and film. TLDs are well established for use in vivo but required expertise and clinical system availability may make them impractical for multifractionated TBI. OSLDs offer quick readout, but recalls have restricted their use. The purpose of this work was to validate the newly available Gafchromic EBT4 film for TBI in vivo dosimetry.

Methods: Film calibration curves were created under standard conditions …

Fructose Induces Inflammatory Activation In Macrophages And Microglia Through The Nutrient-Sensing Ghrelin Receptor, Zheng Shen, Zeyu Liu, Hongying Wang, Danilo Landrock, Ji Yeon Noh, Qun Sophia Zang, Chih-Hao Lee, Yuhua Z Farnell, Zheng Chen, Yuxiang Sun

Faculty, Staff and Student Publications

High fructose corn syrup (HFCS) is a commonly used sweetener in soft drinks and processed foods, and HFCS exacerbates inflammation when consumed in excess. Fructose, a primary component of HFCS; however, it is unclear whether fructose directly activates inflammatory signaling. Growth hormone secretagogue receptor (GHSR) is a receptor of the nutrient‐sensing hormone ghrelin. We previously reported that GHSR ablation mitigates HFCS‐induced inflammation in adipose tissue and liver, shifting macrophages toward an anti‐inflammatory spectrum. Since inflammation is primarily governed by innate immune cells, such as macrophages in the peripheral tissues and microglia in the brain, this study aims to investigate whether …

Faculty, Staff and Student Publications

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-induced coronavirus disease 2019 (COVID-19) pandemic has challenged the current understanding of the complement cascade mechanisms of host immune responses during infection-induced nonresolvable lung disease. While the complement system is involved in opsonization and phagocytosis of the invading pathogens, uncontrolled complement activation also leads to aberrant autophagic response and tissue damage. Our recent study revealed unique pathologic and fibrotic signature genes associated with epithelial bronchiolization in the lung tissues of patients with nonresolvable COVID-19 (NR-COVID-19) requiring lung transplantation. However, there is a knowledge gap if complement components are modulated to contribute to tissue …

Inhibition Of Il-6 Trans-Signaling Promotes Post-Stroke Functional Recovery In A Sex And Dose-Dependent Manner, Cassandra Hall, Dustin T Nguyen, Kate Mendoza, Chunfeng Tan, Anjali Chauhan

Faculty, Staff and Student Publications

Introduction: Elevated circulating IL-6 levels are associated with poorer outcomes after stroke, and increased serum IL-6 levels are linked to a higher risk of stroke. IL-6 binds to soluble IL-6 receptors (sIL-6R) and subsequently to ubiquitously expressed gp130, initiating proinflammatory trans-signaling. This study tested the hypothesis that inhibiting IL-6 trans-signaling by administering soluble (s) gp130 improves long-term functional outcomes in young mice after stroke.

Methods: Recombinant mouse gp130Fc chimera (sgp130) was administered one hour after middle cerebral artery occlusion (MCAO) followed by twice-weekly administration for 2 weeks in mice (8-15 weeks old). Behavioral assessments were done on days 7 and …

The mutational landscape of phylogenetically ultraconserved elements (UCEs), especially those in noncoding DNAs (ncUCEs), and their functional relevance in cancers remain poorly characterized. Here, we perform a systematic analysis of whole-genome and in-house targeted UCE sequencing datasets from more than 3000 patients with cancer of 13,736 UCEs and demonstrate that ncUCE somatic alterations are common. Using a multiplexed CRISPR knockout screen in colorectal cancer cells, we show that the loss of several altered ncUCEs significantly affects cell proliferation. In-depth functional studies in vitro and in vivo further reveal that specific ncUCEs can be enhancers of tumor suppressors (such as ARID1B) …
