Background: There is a need for more effective treatments for idiopathic pulmonary fibrosis (IPF) and progressive pulmonary fibrosis (PPF). Nerandomilast (BI 1015550), an oral preferential inhibitor of phosphodiesterase 4B, is being evaluated in two randomized Phase III trials: FIBRONEER™-IPF (NCT05321069) and FIBRONEER™-ILD (NCT05321082). FIBRONEER™-ON is an open-label extension (OLE) of these studies that will evaluate the long-term safety and efficacy of nerandomilast. Here, we describe the study design of the OLE.

Methods: This prospective 98-week OLE will follow the Phase III parent trials, which are currently underway with 1177 patients enrolled in FIBRONEER™-IPF and 1178 patients …

Can Cta-Based Machine Learning Identify Patients For Whom Successful Endovascular Stroke Therapy Is Insufficient?, Jerome A Jeevarajan, Yingjun Dong, Anjan Ballekere, Sergio Salazar Marioni, Arash Niktabe, Rania Abdelkhaleq, Sunil A Sheth, Luca Giancardo

Faculty, Staff and Student Publications

Background and purpose: Despite advances in endovascular stroke therapy (EST) devices and techniques, many patients are left with substantial disability, even if the final infarct volumes (FIVs) remain small. Here, we evaluate the performance of a machine learning (ML) approach by using pretreatment CTA to identify this cohort of patients that may benefit from additional interventions.

Materials and methods: We identified consecutive subjects with large vessel occlusion (LVO) acute ischemic stroke (AIS) who underwent EST with successful reperfusion in a multicenter prospective registry cohort. We included only subjects with FIV < 30 mL and recorded 90-day outcome (mRS). A deep learning model was pretrained and then fine-tuned to predict 90-day mRS 0-2 by using pretreatment CTA images (DeepsymNet-v3 model pretrained on radiology reports and fine-tuned on detection of unexpected clinical outcomes using brain CTA images [DSN-CTA] model). The primary outcome was the predictive performance of the DSN-CTA model compared with a logistic regression model with clinical variables, measured by the area under the receiver operating characteristic curve (AUROC).

Results: The DSN-CTA model was pretrained on 1542 subjects and …

The Clinical Pharmacogenetics Implementation Consortium's Consensus-Based Framework For Assigning Allele Function., Bailey M. Tibben, Andrea Gaedigk, Li Gong, Katrin Sangkuhl, Michelle Whirl-Carrillo, Mary V. Relling, Roseann S. Donnelly, Teri E. Klein, Kelly E. Caudle

Manuscripts, Articles, Book Chapters and Other Papers

The Clinical Pharmacogenetics Implementation Consortium (CPIC) is dedicated to integrating pharmacogenetic testing into clinical practice by developing and disseminating peer-reviewed, evidence-based gene-drug clinical practice guidelines. A critical component of this effort is the assignment of clinical function to pharmacogene alleles, which informs the translation of genetic test results into actionable prescribing decisions. This technology review outlines the standardized procedures and framework used by CPIC to assign allele clinical functional status through the work of Pharmacogene Curation Expert Panels (PCEPs). These panels, comprising multidisciplinary experts, systematically review and evaluate evidence to assign functional status to pharmacogenetic haplotypes. The process includes rigorous …

Hsp90 Buffers Deleterious Genetic Variations In Brca1, Brant Gracia, Xing-Han Zhang, Patricia Montes, Tin Chanh Pham, Min Huang, Junjie Chen, Georgios Ioannis Karras

Faculty, Staff and Student Publications

Protein-folding chaperone heat shock protein 90 (HSP90) buffers genetic variation in diverse organisms, but the clinical significance of HSP90 buffering in human disease remains unclear. Here, we show that HSP90 buffers mutations in the BRCT domain of BRCA1. HSP90-buffered BRCA1 mutations result in protein variants that retain interactions with partner proteins and strongly rely on HSP90 for protein stability and function in cell survival. Moreover, HSP90-buffered BRCA1 variants confer poly (ADP-ribose) polymerase (PARP) inhibitor resistance in cancer cells. Low-level HSP90 inhibition overcomes this resistance, revealing a cryptic and mutant-specific HSP90-contingent synthetic lethality. Furthermore, by stabilizing metastable variants across the entirety …

Most Alzheimer disease (AD) susceptibility genes have poorly understood roles in the central nervous system (CNS). To address this gap, we systematically characterized 100 conserved candidate AD risk genes using a cross-species strategy in the fruit fly, Drosophila melanogaster. Genes were prioritized based primarily on human functional genomic evidence. We generated custom loss-of-function alleles for each of the conserved fly orthologs. Most of the genes are expressed in the adult brain, including 24 neuron- and 13 glia-specific expression patterns. Overall, we identify 50 candidate AD risk gene homologs with requirements for CNS structure or function, including 18 whose loss of …

The interpretation of genetic variants in inherited diseases, such as inherited platelet disorders (IPDs), remains a major clinical challenge, as most are classified as variants of uncertain significance (VUSs). A key barrier to functional evaluation is the lack of accessible, lineage-appropriate assays that reliably reflect native gene regulation and cell-specific biology. To address this gap, we developed CRIMSON HD (CRISPR-edited megakaryocytes [MKs] for surveying platelet variant functions through homology-directed repair [HDR]), a CRISPR-Cas9 HDR-based genome-editing platform applicable to CD34

Pattern-recognition receptor (PRR) agonists are valuable agents across multiple medical applications, from vaccinology to immune-oncology. However, well-defined and potent small molecule agonists for many PRRs still await discovery and development. Screening of chemical libraries of ~200,000 small molecules for maturation of human monocytic cells by quantifying NF-κB activation and cell adherence was completed. From this screen, we selected a thiazole benzamide derivative, PVP-057, for its robust immunomodulatory properties, low toxicity profile, and concentration-dependent activity. In vitro investigation of pathway and receptor activation reveals that PVP-057 is a Toll-like receptor 3 (TLR3) agonist. As a single-component adjuvant, administered intramuscularly or intradermally …

The interplay between brain metabolism and function supports the brain's adaptive capacity in cognitively demanding processes. Prior work has linked glucose metabolism to resting-state fMRI activity, but often overlooks both hemodynamic confounders in the BOLD signal and the brain's dynamic nature. To address this, we employed a novel effective connectivity decomposition, separating symmetric partial covariance, capturing "true" statistical dependencies between regions, from antisymmetric differential covariance, reflecting directional brain flow. In 42 healthy subjects, we show that partial covariance corresponds to metabolic connectivity across regions, while node directionality relates to standardized uptake value ratio, a proxy for local glucose consumption. We …

Investigating Dysfunctional Cognition Change As A Putative Mechanism Of Cbt For Youth Anxiety, Ocd And Ptsd: Protocol For An Individual Participant Data Meta-Analysis, Ivana Buric, Anke Klein, Ronald M Rapee, Brooke Levis, Philip C Kendall, Eric A Storch, Lynn Mobach

Faculty, Staff and Students Publications

Introduction: Anxiety disorders, obsessive-compulsive disorder (OCD) and post-traumatic stress disorder (PTSD) are common in children and adolescents and can lead to significant impairment. Cognitive behavioural therapy (CBT) with exposure is the first-line treatment, yet approximately half of treated youth do not achieve full remission. Dysfunctional cognitions-negative automatic thoughts, maladaptive beliefs and distorted interpretations-are considered key targets of CBT, but evidence in youth is mixed and underpowered. This study will examine whether change in dysfunctional cognitions mediates treatment outcome in anxiety, OCD and PTSD symptoms and whether this association varies across individual characteristics.

Methods and analysis: An individual participant data meta-analysis …

Calmodulin (CaM) serves an essential role in eukaryotic cells as a Ca2+ sensor. Ca2+ binding leads to conformation changes in CaM that enable engagement of a repertoire of enzymes and the regulation of their catalytic activities. Classically, Ca2+-CaM binds to an inhibitory pseudosubstrate sequence C-terminal to the kinase domain in members of the Ca2+-CaM-dependent protein kinase (CAMK) family and relieves inhibition to promote catalytic activity. Here, we report an unexpected mechanism by which CaM can bind CHK2 kinase to inhibit its kinase activity. Using biochemical, biophysical and structural mass spectrometry, we identify a direct interaction of Ca2+-CaM with the CHK2 …

Resolving The Mysteries Of Brain Clearance And Immune Surveillance, Jonathan Kipnis, Et Al.

2020-Current year OA Pubs

Recent advances are transforming our understanding of brain fluid dynamics, highlighting cerebrospinal fluid (CSF) flow as a key process in brain waste clearance. While debates persist regarding its anatomical pathways and regulatory mechanisms, certain core principles have become widely accepted. CSF influx occurs primarily along periarterial spaces, solute clearance follows multiple routes, and glymphatic and meningeal lymphatic systems are functionally connected. Brain clearance is influenced by vascular pulsation, neural activity, and sleep. Immune cells at brain-border niches both monitor solute efflux and modulate flow, linking brain clearance to neuroimmune interactions. A deeper understanding of brain clearance could unlock new therapeutic …

Background/Objectives: One of the main reasons for discrepancies in the role of vitamin D in ART could be the measurement of the conventional biomarker 25(OH)D₃. It is known that this value is affected by multiple factors, such as tissue origin, assay variability, classification criteria, and potential storage-related degradation. In this study, we investigate 24,25(OH)₂D₃ as a new biomarker to improve vitamin D assessment in women’s reproductive health, particularly regarding oocyte development. Methods: A prospective cohort study including 35 oocyte donors undergoing controlled ovarian stimulation, who were recruited between October and November 2017, was conducted. Vitamin …

Suhandynata, David J. Grelotti, Marilyn A. Huestis, Kyle F. Mastropietro, Igor Grant, Thomas D. Marcotte

Institute of Emerging Health Professions Faculty Papers

BACKGROUND: Several US states have per se laws using 2 or 5 ng/mL of delta-9-tetrahydrocannabinol (THC) as cutpoints for driving under the influence of cannabis, while some have zero-tolerance statutes. These cutpoints are considered prima facia evidence of driving impairment.

METHODS: In a cohort of people who regularly use cannabis (N = 190) we measured baseline concentrations of THC after instructing participants to abstain from cannabis for at least 48 hours. Baseline driving performance was evaluated using a driving simulator. We also measured blood THC concentrations serially following a smoking session (placebo or active cannabis).

RESULTS: Forty-three percent of the …

We analyze 10,986 participants (mean age 77; 63% women; 54% non-White) across seven U.S. cohorts to study the relationship between mitochondrial DNA (mtDNA) heteroplasmy and nuclear DNA methylation. We identify 597 CpGs associated with heteroplasmy burden, generally showing lower methylation. These CpGs are enriched in dynamically regulated island shores and depleted in CpG islands, indicating involvement in context-specific rather than constitutive gene regulation. In HEK293T cells, we introduce a truncating mtDNA mutation (MT-COX3, mt.9979) and observe a positive correlation between variant allele fraction and methylation at cg04569152, supporting a direct mtDNA-nDNA epigenetic link. Many heteroplasmy-associated CpGs overlap with known methylation-trait …

Renal cell carcinoma (RCC) patients with hypercalcemia (HC) have worse outcomes. HC often involves PTHrP, and the role of HIF-2 is incompletely understood. Leveraging RCC tumorgraft (TG) models of HC, which were characterized by tumor cell autonomous inflamatory/immune signatures, we show that HIF-2 inhibition with PT2399 frequently normalized calcium, downregulated circulating PTHrP and reduced HIF-2 binding to the PTHLH (PTHrP) promoter. Likely contributing to the selective induction of PTHrP in a subset of HIF-2-dependent tumors, the PTHLH locus was generally more accessible in TG(HC). However, PTHLH chromatin accessibility was grossly unaffected by PT2399, unlike elsewhere (including EPO locus in a …

Studies have implicated perturbations in the postnatal development of the gut microbiome as a contributing factor to childhood undernutrition. Compared to a standard ready-to-use supplementary food, a microbiome-directed complementary food (MDCF-2) designed to repair these perturbations produced superior improvements in ponderal and linear growth in clinical trials of Bangladeshi children with moderate acute malnutrition. Here, "reverse translation" experiments are performed where intact fecal microbiomes collected from trial participants before and at the end of treatment are introduced into female gnotobiotic mice just after delivery of their pups. Pups received diets designed to resemble those consumed by children in the trials …

Statistically Significant Association Does Not Imply Improvement In Prediction Of Clinical Outcomes, Shu Jiang, Bernard A Rosner, Graham A Colditz

2020-Current year OA Pubs

UNLABELLED: In the current landscape of clinical studies, the concept of statistically significant association is often mixed up with the expectation of improved prediction performance. We discuss the two concepts, association and prediction, and present the epidemiologic principles and statistical constructs that underlie the discrepancy between statistically significant associations and the rationale for their lack of impact on improving prediction in terms of discrimination. This issue is illustrated using an existing breast cancer dataset. The concept of statistically significant association should not be mixed up with the expectation of improved discrimination performance. Although some markers may not markedly improve discrimination, …

Fucosylated N-Glycan Landscape Of Triple-Negative Breast Cancer, Danielle A Scott, Souvik Seal, Laura Spruill, Jaclyn Dunne, Graham Colditz, Anand S Mehta, Richard R Drake, Marvella E Ford, Peggi M Angel

2020-Current year OA Pubs

UNLABELLED: Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer lacking targeted therapies. Although aberrant N-glycosylation is a hallmark of malignancy, the specific roles of core-fucosylated (CF) and outer arm-fucosylated (OAF) N-glycans in TNBC progression and patient survival remain underexplored. This study utilized multiplexed glycomics by matrix-assisted laser desorption/ionization imaging mass spectrometry to spatially profile 348 N-glycans in 59 TNBC tumors with clinical characteristics including survival data. Spatial analysis revealed distinct localization patterns of CF and OAF isomers within tumor microenvironments. Strikingly, OAF glycans, but not CF, were strongly associated with tumor stage, with expression increasing from stage …

Dysregulation of RNA binding proteins (RBPs) is a hallmark in cancerous cells. In acute myeloid leukaemia (AML) RBPs are key regulators of tumour proliferation. While classical RBPs have defined RNA binding domains, RNA recognition and function in AML by non-canonical RBPs (ncRBPs) remain unclear. Given the inherent complexity of targeting AML broadly, our goal was to uncover potential ncRBP candidates critical for AML survival using a CRISPR/Cas-based screening. We identified the glycolytic enzyme glyceraldehyde-3-phosphate dehydrogenase (GAPDH) as a pro-proliferative factor in AML cells. Based on cross-linking and immunoprecipitation (CLIP), we are defining the global targetome, detecting novel RNA targets mainly …

Harmonizing Mouse Anatomy Terminology: A Common Language?, Jesús Ruberte, Paul N Schofield, John P Sundberg, Sergi Olvera-Maneu, Ana Carretero

Faculty Research 2025

The mouse remains the principal animal model for investigating human diseases due, among other reasons, to its anatomical similarities to humans. Despite its widespread use, the assumption that mouse anatomy is a fully established field with standardized and universally accepted terminology is misleading. Many phenotypic anatomical annotations do not refer to the authority or origin of the terminology used, while others inappropriately adopt outdated or human-centric nomenclature. This inconsistency is further exacerbated by the limited availability of comprehensive anatomical references, often compelling researchers to rely on "do-it-yourself" anatomical interpretations when characterizing disease models-an approach that increases the risk of inaccuracies …

INTRODUCTION: We investigated sex-specific gene expression associations with the neuropathology and cognitive manifestation of Alzheimer's disease (AD) leveraging single-nucleus transcriptomic datasets including 2.84 million nuclei from the dorsolateral prefrontal cortex (DLPFC).

METHODS: We delineated the full scope of sex-specific transcript associations, differential gene expression, signaling pathway, and cell-cell communication network changes in eight major DLPFC cell types.

RESULTS: Nine female-specific associations were identified and replicated, involving ADGRV1, OR3A3, IFI27L1, LYRM1, STAP2, TSTD2, PDYN, and TMEM50B. We observed the preponderance of protective female-specific associations in neurons. Sex-specific genes were enriched in the immune-, inflammation-, and damage-related stress-response pathways. Six ITGB1-mediated microglia-specific …
