Soft-tissue sarcomas (STS) are characterized by abundant extracellular matrix (ECM) deposition, yet the functional contribution of specific ECM components remains poorly understood. In this study, we identify periostin (POSTN), a matricellular protein, as a regulator of sarcoma progression and the tumor immune microenvironment. Analysis of human sarcoma datasets revealed that high POSTN expression correlates with poor prognosis and elevated expression of ECM-related and myeloid cell–associated genes. In murine genetic models of sarcoma, tumors expressing high levels of Postn displayed enhanced expression of ECM genes and monocyte-recruiting cytokines. Functional silencing of Postnin vivo reduced tumor growth without altering tumor cell …

Bayesian Integrated Learning Of Longitudinal Dose-Response Relationships Via Decentralized Clinical Trials, Jingyi Zhang, Tuo Wang, Yongming Qu, Fangrong Yan, Suyu Liu, Ruitao Lin

Faculty, Staff and Student Publications

Decentralized clinical trials (DCTs) extend trial activities beyond traditional sites, enhancing access, convenience, efficiency, and result generalizability. They are particularly promising for chronic conditions like diabetes and obesity, which require longer study durations to evaluate drug effects. However, decentralized data collection raises concerns about increased variability and potential biases. This paper presents a novel Bayesian integrated learning procedure to analyze dose-response relationships using longitudinal data from a phase II DCT that combines centralized and decentralized data collection. We generalize a parametric exponential decay model to handle mixed data sources and apply Bayesian spike-and-slab priors to address biases and uncertainties from …

Bayesian Prediction Of Event Times Using Mixture Model For Blinded Randomized Controlled Trials, Jingyan Fu, Dan Zhao, Donia Skanji, Hua Liu, Rui Sammi Tang, Ying Yuan

Faculty, Staff and Student Publications

Accurate prediction of key milestone dates, such as the timing of interim and final analyses, is crucial in event-driven clinical trials with time-to-event endpoints. These predictions facilitate timely decision-making, enhance strategic planning and optimize resource allocation while minimizing patient exposure to potentially ineffective or harmful therapies. Existing methods for predicting event timing in blinded randomized clinical trials (RCTs) typically assume identical time-to-event distributions for the treatment and control arms, implying no treatment effect. This assumption fails when the treatment is more effective than the control, which is often the very outcome the trial seeks to detect, leading to biased predictions. …

Normalization Of Temperature Effects For Quality Assurance Of Quantitative Prostate Apparent Diffusion Coefficient Imaging Across Multiple Sites, Ken-Pin Hwang, Joshua Yung, R Jason Stafford, Caroline Chung, Aradhana M Venkatesan Dec 2025

Normalization Of Temperature Effects For Quality Assurance Of Quantitative Prostate Apparent Diffusion Coefficient Imaging Across Multiple Sites, Ken-Pin Hwang, Joshua Yung, R Jason Stafford, Caroline Chung, Aradhana M Venkatesan

Faculty, Staff and Student Publications

Background: Apparent Diffusion Coefficient (ADC) as measured by diffusion weighted imaging is known to negatively correlate with prostate tumor aggressiveness. Heterogeneity in system and protocol performance causes potential variability in ADC acquired across a large scanner network, prompting a need to evaluate quantitative ADC from a prostate-specific MR diffusion protocol as part of quality assurance (QA). Due to the temperature dependence of ADC, repeatability and reproducibility assessments typically require phantoms to maintain a temperature of 0°C, imposing a considerable burden when assessing large numbers of scanners.

Purpose: To develop a QA procedure at room temperature for assessing the reproducibility of …

Fecal Microbiota Transplant (FMT) is a treatment for recurrent Clostridium difficile infections and is being explored for other clinical applications, from alleviating digestive and neurological disorders, to restoring microbiomes impacted by cancer treatment. Quantifying the extent of engraftment following an FMT is important in understanding a recipient's response to treatment. Engraftment and clinical response need to be investigated independently to evaluate an FMT's role (or lack thereof) in achieving a clinical response. Standardized bioinformatics methodologies for quantifying engraftment extent would not only improve assessment and understanding of FMT outcomes, but also facilitate comparison of FMT results and protocols across studies. …

Fusobacterium nucleatum (Fn) is commonly enriched in colorectal cancer (CRC) and associated with poor outcomes, though its mechanisms remain unclear. Our study investigated how Fn affects the tumor microenvironment through single-cell transcriptomic analyses of 42 CRC patient tissues, comparing Fn-positive and Fn-negative tumors. We discovered that Fn impairs IgA plasma cell development and secretory IgA (sIgA) production by disrupting communication with tumor-associated macrophages. Additional experiments in germ-free mice, together with our re-analysis of a publicly available single-cell RNA-seq data set from a CRC mouse model with an intact gut microbiome–both models having been orally gavaged with Fn–jointly validated the causal …

Myocardial infarction (MI) affects millions of people worldwide, causing irreversible injury to the heart and impairing cardiac function1. In both mouse and pig MI models, activating YAP in cardiomyocytes (CMs) stimulates regenerative repair2,3. Here we developed an adeno-associated virus 9 (AAV9)-based therapy, termed CM-YAPon, which enables transient expression of an active YAP variant (YAP5SA) in CMs following exposure to the small molecule LMI070. A single LMI070 dose in mice triggers YAP5SA expression, CM cell cycle re-entry, and reprogramming of the cardiac microenvironment. YAP5SA induction after MI rapidly improves cardiac function while pre-MI induction confers …

A Narrative Review Of Dual Loyalty Conflicts In Custodial Settings And Implications For Community Practice, Michelle Suh, Marc David Robinson, Holland Kaplan

Center for Medical Ethics and Health Policy Staff Publications

Dual loyalty dilemmas are conflicts between health care professionals' obligations toward their patients and third-party interests. These conflicts are more common and starker in custodial settings, such as jails and prisons, military detention facilities, immigration detention centers, and involuntary psychiatric institutions. Despite encountering patients in custody, health care professionals (HCPs) in community settings have limited knowledge and training. In this narrative review, we examined dual loyalty conflicts faced by HCPs working in custodial settings and then applied the identified themes to community-based hospitals where HCPs care for patients in custody. We searched databases for original papers relating to patients in …

Batten disease is characterized by early-onset blindness, juvenile dementia and death within the second decade of life. The most common genetic cause are mutations in CLN3, encoding a lysosomal protein. Currently, no therapies targeting disease progression are available, largely because its molecular mechanisms remain poorly understood. To understand how CLN3 loss affects cellular signaling, we generated human CLN3 knock-out cells (CLN3-KO) and performed RNA-seq analysis. Our multi-dimensional analysis reveals the transcriptional regulator YAP1 as a key factor in remodeling the transcriptome in CLN3-KO cells. YAP1-mediated pro-apoptotic signaling is also increased as a consequence of CLN3 functional loss in retinal pigment …

In the studies of Inherited Retinal Diseases (IRDs), the knockout of traditional animal models like mice often fails to accurately replicate human phenotypes due to genetic and anatomical differences. Human retinal organoids (ROs) derived from stem cells have emerged as promising developmental models in retinal studies to delineate cell growth, but their ability to represent the characteristics of late-onset IRDs remains unclear. This study aims to validate ROs as a disease model for Stargardt's Disease (STGD) caused by ABCA4 mutations. Using single-cell RNA sequencing, ROs from 2 STGD patients were compared with healthy control-derived ROs at two developmental stages on …
