The Role Of Chimeric Antigen Receptor Regulatory T Cells In Promoting Immune Tolerance In Solid Organ Transplantation: Mechanisms And Therapeutic Potential, Maher S. Alwethaynani

Saudi Medical Journal

Solid organ transplantation (SOT) is a life-saving procedure for patients with end-stage organ failure; however, lifelong immunosuppressant use is needed to prevent allograft rejection. These drugs increase the risk of non-Hodgkin lymphoma, liver, kidney, and lung cancers, and heighten susceptibility to oncogenic viruses, including hepatitis B and Epstein-Barr virus. The usage of chimeric antigen receptor (CAR) regulatory T (Treg) cells is a promising approach to induce transplant tolerance while minimizing dependence on immunosuppressants. The CAR Tregs offer the potential to enhance graft survival and quality of life by reducing immunosuppressant-related morbidity and mortality. Despite remarkable progress in transplantation tolerance, challenges …

Meta-Analysis On The Effect Of Tai Chi Chuan On Human Biomechanics And Health From (2021–2025), Bijad S. Alqahtani, Husam A. Almalki

Saudi Medical Journal

Objective: Prior reviews emphasize overall health outcomes of Tai Chi Chuan (TCC) but rarely resolve the biomechanical intermediates (such as Center of Mass (CoM)–Center of Pressure (CoP) control, joint loading) that link practice to clinical function—knowledge that matters for balance, fall risk, and osteoarthritic knee load management. This systematic review and meta-analysis aim to test the null hypothesis that TCC produces no improvement versus comparators in (i) biomechanical stability indices (mediolateral/anterior–posterior CoM–CoP separation; COP Root Mean Square RMS) and (ii) related clinical functions (such as Time up and go (TUG), Berg balance scale (BBS), Western Ontario and McMaster Universities Osteoarthritis …

Development Of A Structurally Distinct Topbp1 Inhibitor That Enhances Parp Blockade And Reverses Osimertinib Resistance, Fang-Tsyr Lin, Shwu-Jiuan Lin, Kang Liu, Yang Xiao, Lidija A Wilhelms Garan, Helena Folly-Kossi, Weei-Chin Lin

Faculty, Staff and Students Publications

Therapeutic resistance remains a major challenge in cancer treatment, driven by compensatory signaling and stress response pathways that sustain tumor survival. Topoisomerase IIβ-binding protein 1 (TopBP1), a multifunctional scaffold protein with nine BRCT domains, integrates replication stress signaling with oncogenic networks and is frequently overexpressed in aggressive cancers. Its BRCT7/8 domains mediate critical interactions with E2F1, mutant p53, MIZ1, PLK1, and CIP2A, making TopBP1-BRCT7/8 an attractive therapeutic target. Using docking-guided screening and structure-activity relationship–driven optimization, we developed CS18 as a potent and selective BRCT7/8 inhibitor that disrupts oncogenic TopBP1 complexes without interfering with DNA replication. CS18 suppresses MYC transcriptional programs, …

Terahertz Electromagnetic Effects And Chirality-Induced Spin Selectivity In Dna, F. Matthew Mihelic Md

Faculty Publications

The effects of terahertz electromagnetic stimulation of the DNA molecule can be understood through modeling of the quantum logical mechanics of the DNA molecule.  Coherent conduction of electron spin states along the aromatic nucleotide base pairs and chirality-induced spin selectivity are two characteristics of the DNA molecule that are involved in the precise separation of the double-stranded DNA molecule at a specific location.  Such modeling can inform predictions of DNA strand separation and has significant implications for understanding DNA transcription bubble formation.

Automated Flim-Fret Segmentation Within Rnp Condensates, Noah D Powell, Joshua M Marcus, Leyla E Fahim, Jason E Lee

Faculty, Staff and Students Publications

Ribonucleoprotein (RNP) condensates are membraneless organelles that exist alongside many RNA-driven processes, such as transcription and splicing. Despite their ubiquity, the biological necessity of forming a condensed phase remains unclear, particularly because the same RNP components exist both within these organelles and in the surrounding dilute phase. Most current methods for studying biochemical interaction dynamics within condensates rely on in vitro reconstitution of minimal factors or low-throughput single-molecule studies. However, RNP condensates are complex organelles containing tens to hundreds of proteins and hundreds to thousands of different RNAs. Here, we describe a scalable, high-throughput fluorescence microscopy–based approach to analyze protein–protein …

Introduction: Cancer is the most common cause of disease-related mortality in children, highlighting the urgent need for improved care in this population. It is estimated that >15% of children diagnosed with cancer harbour a germline pathogenic variant in a cancer predisposition gene which confers an increased risk to develop cancer. There are over 100 genes associated with cancer predisposition syndromes (CPSs) and greater availability and acceptability of genetic testing in the last decade has facilitated their recognition in childhood. However, individually, each of these CPSs is rare, impeding robust research and advancement of clinical care. Once a specific CPS is …

Protocadherin 9 Promotes Cell Survival Of Different Bipolar Cell Types In The Developing Mouse Retina, Marlon F Mattos, Daniela Becerril, Jingyao Guo, Collin Todora, Cesiah C Gomez, Elizabeth Zuniga-Sanchez

Faculty, Staff and Students Publications

Neural circuit assembly relies on different neuronal types coming together to form a functional circuit. The question of how the appropriate number of each type is integrated into an emerging circuit remains relatively unknown. To answer this question, we used the mouse retina to uncover the molecular mechanisms responsible for neuron-type integration in a developing circuit. In the mammalian retina, bipolar cells (BCs) are a class of interneurons that relay visual information from photoreceptors to ganglion cells. Extensive studies have shown there are 15 distinct BC types: 6 types of OFF cone bipolars, 8 types of ON cone bipolars, and …

Hyperadhesive Von Willebrand Factor Contributes To Pathogenesis Of Preeclampsia, Yajuan Wang, Chenyu Wang, Katie L Houck, Xiaoli Gao, Yuanyuan Chen, Xin Xu, Xue Zhao, Miguel A Cruz, Shu Zhang, Chester Q Li, Fengxia Xue, Min Li, Swati Shree, Jing-Fei Dong, Cha Han

Children’s Nutrition Research Center Staff Publications

Background: Preeclampsia is the most common complication of pregnancy, significantly affecting maternal and fetal health, and is characterized by placental and systemic endotheliopathy. Patients with preeclampsia have elevated levels of VWF (von Willebrand Factor), which is associated with poor clinical outcomes. However, whether VWF serves as a marker for endotheliopathy or contributes to the pathogenesis of preeclampsia remains poorly understood.

Methods: We investigated the role of hyperadhesive VWF in the development of preeclampsia by studying patients, evaluating mouse models, and performing in vitro experiments.

Results: We show that patients develop VWF- and fibrin-rich thrombosis in the placenta and have significantly …

Postpartum hemorrhage remains a leading cause of maternal morbidity and mortality, and Pitocin administration is an important component of hemorrhage prevention and management during cesarean delivery. Variation in Pitocin timing, dosing, method of administration, and adherence to evidence-based recommendations may compromise patient safety and create barriers to standardized obstetric anesthesia care. The purpose of this Doctorate of Nurse Anesthesia Practice quality improvement project was to evaluate current anesthesia provider practices for Pitocin administration during cesarean delivery, compare observed practices with the California Maternal Quality Care Collaborative hemorrhage toolkit and Society for Obstetric Anesthesia and Perinatology Enhanced Recovery After Cesarean recommendations, …

Ai-Driven Segmentation And Volumetric Response Modeling Of Liver Regions To Radiotherapy, Aashish Chandra Gupta

Dissertations and Theses (Open Access)

In liver-directed radiotherapy (RT), liver regions receiving higher doses typically undergo atrophy while contralateral/adjacent lower-dose regions may exhibit compensatory hypertrophy through regeneration of healthy tissue. Optimizing the RT plan to promote regional hypertrophy while minimizing the risk of developing atrophy has the potential to enhance post-RT liver function and long-term survivorship. However, current clinical practice largely relies on global liver dose-volume metrics during RT-planning, which may obscure favorable dose-response correlation and limit actionable guidance for clinicians. Therefore, we hypothesized that post-RT regional liver response is governed by a combination of region-specific dose-volume and patient clinical features, and that these responses …

Faculty, Staff and Student Publications

Background and objectives: The apolipoprotein E (APOE) haplotypes are known to be associated with dementia, with the ε4 haplotype associated with higher risk. It has been suggested that the APOE ε2 allele serves as a protective factor for dementia. However, data on the effects of the homozygous APOE ε2/ε2 genotype are limited, likely due to the rarity of the APOE ε2/ε2 genotype. Furthermore, the association between APOE genotypes and dementia may differ across self-reported race. We aim to investigate the association between APOE genotypes and dementia overall and across self-reported race, with a focus on the potential protective …

Exploring Traditional Breast Cancer Risk Genes Among Aboriginal And Torres Strait Islander Women, Katie Meehan, Leanne Pilkington, Azim Khan, Nicholas Pachter, Lisa Spalding, Ayeisha Milligan Armstrong, Cameron Redfern, Andrew Redfern

Research outputs 2022 to 2026

Background: Germline pathogenic variants in BRCA1/2 increase breast and ovarian cancer risk, but their prevalence in Aboriginal and Torres Strait Islander (herein referred to as Aboriginal) families has never been studied. Consequently, their contribution to breast cancer in this population is unknown.

Methods: This retrospective cohort study included 259 Aboriginal women and 789 age- and remoteness-matched non-Aboriginal women diagnosed with breast cancer (2001–2016). We assessed family history, genetic service referral and testing rates, and pathogenic variant rates in the context of testing access.

Results: Family history data were available for more Aboriginal than non-Aboriginal cases (46% vs. 34%, p < 0.001), with no difference in reported first-degree relatives with breast (22.5% vs. 22.4%, p = 0.98) or ovarian cancer (4.2% vs. 2.2%, p = 0.29). Similar proportions were referred to genetic services for testing eligibility (5.4% vs. 7.2%, p = 0.392). Of those referred, similar proportions were offered testing (86% vs. 81%, p = 0.66). Across the full cohort, BRCA1/2 pathogenic variants were detected in 0.77% of Aboriginal versus 2.4% of non-Aboriginal women (p = 0.127); any pathogenic gene variant was detected in 0.77% versus 3.0% (p = 0.039).

Musical Training Increases Anticipatory Responding And Predictive Control In Sequence Learning, Li Ann Leow, Jarrad Lum, Sara Johnson, Emily Corti, Welber Marinovic

Research outputs 2022 to 2026

Musicians demonstrate advantages in acquiring motor sequences, showing faster learning and better explicit sequence knowledge than non-musicians. However, it is unclear whether this advantage extends beyond acquisition to the consolidation phase, which is when newly learned skills stabilize and become resistant to interference. Additionally, while interference from executing competing motor tasks is well-established, less is known about whether purely sensory information presented after learning can disrupt consolidation of a bimodal motor sequence. We investigated how post-acquisition sensory interference affects performance of a learned audio-visual sequence, and whether musical training moderates this vulnerability. Participants first learned an explicit sequence in a …

Gut Microbiome Changes In Preclinical Alzheimer’S Disease, D. M. Sithara Dissanayaka, Stephanie R. Rainey-Smith, Hamid R. Sohrabi, Thilini N. Jayasinghe, Vincent Ho, Vijay Jayasena, Kevin Taddei, Colin L. Masters, Ralph N. Martins, W. M.A.D.Binosha Fernando

Research outputs 2022 to 2026

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that develops many years before clinical symptoms appear. The biological changes involved in the earliest stages remain poorly understood, particularly during the preclinical stage. Our previous work has identified gradual gut microbial and metabolic changes during this stage, suggesting these may represent early biological shifts that precede disease progression. Recent studies suggest that the gut microbiome may contribute to early AD processes through its effects on immune regulation, metabolism, and gut–brain communication. Changes in gut microbial composition, including reduced levels of short-chain fatty acid (SCFA)-producing bacteria, such as Faecalibacterium, Roseburia, and Eubacterium, …
