KRAS is among the most frequently mutated oncogenes in cancer, and for decades, efforts at pharmacological blockade of its function in solid cancers have been unsuccessful. A notable advance in this endeavor is the recent development of small molecule KRAS inhibitors, which enable direct targeting of the mutant oncoprotein. Here, we comprehensively evaluate the pre-clinical efficacy of BI-2493 a panKRASi, a first-in-class allele agnostic mutant KRAS inhibitor, in pancreatic ductal adenocarcinoma (PDAC). We report effective tumor growth suppression across a broad range of models, including cell lines, patient-derived xenografts (PDXs), syngeneic orthotopic models, and prolonged survival in genetically engineered mouse …

Aberrant levels or structures of RNA isoforms are a hallmark of many cancers, including acute myeloid leukemia (AML), yet their role in AML chemoresistance remains unclear. We conducted a paired analysis of RNA isoform changes in patients with AML before therapy and at relapse after chemotherapy and identified intragenic DNA methylation at the proximal promoter of the transcription factor RUNX1, which resulted in elevated expression of the long-isoform RUNX1C through its alternative distal promoter. The unique N-terminal region of RUNX1C orchestrated an isoform-specific transcriptional program that promoted chemoresistance, with its direct target BTG2 playing a role in chemotherapy resistance. …

Persistent Na+ Current Couples Spreading Depolarization To Seizures In Scn8a Gain-Of-Function Mice, Isamu Aiba, Yao Ning, Jeffrey L Noebels

Faculty, Staff and Students Publications

Spreading depolarization (SD) is a slowly propagating wave of massive cellular depolarization that transiently impairs the function of affected brain regions. Although SD typically arises as an isolated hemispheric event, we previously reported that reducing M-type potassium current (IKM) by ablation of Kcnq2 in forebrain excitatory neurons results in tightly coupled spontaneous bilateral seizure–SD complexes in the awake mouse cortex.

Here we find that enhanced persistent Na+ current attributable to gain-of-function mutations in Scn8a (N1768D/+, hereafter D/+) produces a similar compound cortical excitability phenotype. Chronic direct-current (DC)-band EEG recording detected spontaneous bilateral seizure–SD complexes accompanied by seizures with …

Partial phenotypic overlap has been suggested between multiple system atrophy and spinocerebellar ataxia 27B, the autosomal dominant ataxia caused by an intronic GAA•TTC repeat expansion in FGF14. In this study, we investigated the frequency of FGF14 GAA•TTC repeat expansion in clinically diagnosed and pathologically confirmed multiple system atrophy cases. We screened 657 multiple system atrophy cases (193 clinically diagnosed and 464 pathologically confirmed) and 1003 controls. The FGF14 repeat locus was genotyped using long-range PCR and bidirectional repeat-primed PCRs, and expansions were confirmed with targeted long-read Oxford Nanopore Technologies sequencing. We identified 19 multiple system atrophy cases carrying an FGF14 …

2020-Current year OA Pubs

BACKGROUND: Spectrophotometric testing to detect sample hemolysis is available from central laboratory chemistry analyzers. While the cause and preventative measures are known, hemolysis continues to be a common preanalytical error, especially for specimens collected from the emergency department (ED) and intensive care units (ICUs) where point-of-care analyzers are commonly used for whole blood electrolyte testing. Recently, these analyzers have employed technology to detect hemolysis directly on whole blood samples.

METHODS: Experienced laboratorians and physicians from the clinical laboratory, ED, adult and neonatal ICUs provide a summary of the medical importance of in vitro hemolysis. Causes for in vivo hemolysis are …

Amoxicillin Vs Ceftriaxone To Treat Pneumonia Caused By Amoxicillin-Non-Susceptible Streptococcus Pneumoniae, Daniel M Musher

Faculty, Staff and Students Publications

Although the article by J Càmara, I Grau, A González-Díaz, N Santos, et al. (Antimicrob Agents Chemother 69:e00237-25, 2025, https://doi.org/10.1128/aac.00237-25) suggests that ceftriaxone is greatly superior to amoxicillin in treating pneumonia due to pneumococci with an MIC > 2 mg/L, much of the difference in efficacy of the two drugs may have been due to dosage, route, and times of administration of the amoxicillin.

Inhalation of Rhodococcus equi causes severe pneumonia in humans and animals worldwide, most commonly affecting horse foals. The standard for preventing R. equi pneumonia in foals is transfusion of hyperimmune plasma, which is expensive and carries the risk of adverse effects. Our goal was to passively immunize foals against R. equi by nebulizing mRNA encoding an equine monoclonal antibody (mAb) against the virulence-associated protein A (VapA) directly into the lungs. VapA-specific memory B cells from an immunized horse were used to identify and select the sequence for an equine immunoglobulin (Ig)G1 mAb. In vitro-transcribed mRNA encoding this sequence expressed …

Psma-1-Dota Potentially For Effective Targeted Radioligand Therapy Of Prostate Cancer, Xinning Wang, Olga Sergeeva, Maxim Sergeev, Lifang Zhang, Zoey Lockwood, Zhenghong Lee, James P. Basilion

Faculty Scholarship

Purpose: While PSMA-targeted radioligand therapy (RLT) has shown remarkable efficacy for treating end-stage prostate cancer, the α-emitting RLT often results in severe salivary gland toxicity, limiting its use. Various strategies to mitigate this side effect have been attempted with limited success. Accordingly, this study introduced a new PSMA-targeting ligand with more favorable binding characteristics than the existing ligands. Procedures: The binding affinity of PSMA-1-DOTA to PSMA was compared with that of PSMA-11 and PSMA I&T. Comparison of uptake in the salivary glands, kidneys and PC3pip tumor cells in the xenograft mouse models between [⁶⁸Ga]Ga-PSMA-1-DOTA, [⁶⁸Ga]Ga-PSMA-11 and [⁶⁸Ga]Ga-PSMA I&T was conducted …

How Life-Cycle Real-World Evidence Can Bridge Evidentiary Gaps In Precision Oncology, Emanuel Krebs, Deirdre Weymann, Tania M. Bubela, Dean A. Regier

Office of the Provost

Precision oncology uses omics-based diagnostic technologies to inform histology-agnostic cancer treatment. To date, health system implementation remains limited owing to high uncertainty in regulatory and reimbursement evidence submissions. In this perspective, we describe a life-cycle approach to the evaluation of precision oncology technologies that addresses evidentiary uncertainty and is grounded in real-world evidence (RWE) derived using data routinely collected by healthcare systems. We consider the role for RWE in international regulatory and reimbursement decision-making, review common biases for observational precision oncology evaluations, make specific recommendations for RWE study design and analysis, and specify healthcare system requirements for data collection. We …

INTRODUCTION: Copperheads and cottonmouths are responsible for most snake envenomations in Louisiana. While the United States Food and Drug Administration has approved both Crotalidae polyvalent immune Fab (FabAV) and Crotalidae immune F(ab') (Fab2AV) for Agkistrodon envenomations, data is limited comparing their efficacies for this indication. METHODS: This is a retrospective study comparing FabAV to Fab2AV in the treatment of suspected Agkistrodon envenomations in Louisiana between April 2017 and October 2024. Cases identifying rattlesnakes were excluded. The primary outcome was the need for additional antivenom doses to achieve control after the initial antivenom dose. RESULTS: One hundred fifty-eight patients received FabAV …

Emerging Clinical Role Of Tavapadon, A Novel Dopamine Partial Agonist, In The Treatment Of Parkinson’S Disease, Alan D. Kaye, Bennett M. Ford, Brennan M. Abbott, Kalob M. Broocks, Sofia Novacic, Sahar Shekoohi

School of Medicine Faculty Publications

Tavapadon, a novel oral dopamine-D1R/D5R partial agonist, has been studied in recent years for the treatment of late-stage development Parkinson’s disease (PD). Levodopa, a dopamine precursor that currently remains the gold-standard first-line therapy for PD motor symptoms, serves as a benchmark against emerging dopaminergic agents. By selectively activating D1-family receptors on direct-pathway medium neurons, Tavapadon differs in that it delivers levodopa-level motor benefit while avoiding its many D2R/D3R-mediated adverse effects. In placebo-controlled trials, Tavapadon produced clear, clinically meaningful gains in motor function and day-to-day activities, as captured by the Unified Parkinson’s Disease Rating Scale (UPDRS). Recent late-stage results have revealed …

Subtype-Specific Her3 Enrichment In Basal-Like Breast Cancer Is Regulated Via The Gata2/Gata3–Foxa1 Axis, Congcong Tan, Hui Lyu, Sanbao Ruan, Yakun Wu, Margaret E. Larsen, Shou Ching Tang, Bolin Liu

School of Medicine Faculty Publications

Basal-like breast cancer (BLBC) is a major subtype of triple-negative breast cancer (TNBC), characterized by aggressive behavior, limited treatment options, and poor prognosis. While HER3 overexpression is frequently observed in TNBC and associated with poor outcomes, its subtype-specific expression and therapeutic potential remain unclear. Here, we demonstrated that HER3 signaling is selectively hyperactivated in BLBC compared to claudin-low breast cancer (CLBC) using transcriptomic profiling. Histone deacetylase inhibitors (HDACi), Romidepsin and Panobinostat, exerted potent antitumor effects on BLBC by selectively downregulating HER3 expression. HER3 levels were positively correlated with FOXA1, a key transcriptional activator. Mechanistically, we identified GATA2 and GATA3 as …

Transcutaneous Spinal Stimulation Paired With Visual Feedback Facilitates Retention Of Improved Weight Transfer Toward The Affected Side In People Post-Stroke, Hyunje Park, Beom-Chan Lee, Dimitry Sayenko, Sheng Li, Seoung Hoon Park

The Brown Foundation: Institute of Molecular Medicine

Background: Many individuals with hemiparesis after stroke are reluctant to transfer their body weight toward the affected side and rely more heavily on the unaffected leg while walking. Although visual feedback (VF) has been utilized to improve their weight transfer during walking, the effects of transcutaneous spinal stimulation (TSS) paired with VF during locomotor training in people post-stroke remain largely unexplored. The purpose of this study, therefore, was to determine whether phasic TSS paired with VF regarding weight shifting to the affected leg during treadmill walking would enhance weight transfer toward the affected side.

Methods: Eleven individuals post-stroke participated in …

Chp1 Promotes Lipid Droplet Growth And Regulates The Localization Of Key Enzymes For Triacylglycerol Synthesis, Guang Yang, Ximing Du, Dougall Norris, Armella Zadoorian, Yuyuan Zheng, Mingming Gao, Andrew J Brown, Shane T Grey, Chun Zhou, Hongyuan Yang

Faculty, Staff and Student Publications

The glycerol-3-phosphate (G-3-P) pathway is central to the synthesis of triacylglycerols (TAGs) and glycerophospholipids, essential for membrane biogenesis and lipid storage. The first and rate-limiting step in this pathway is catalyzed by glycerol-3-phosphate acyltransferases (GPATs), with microsomal GPAT3 and GPAT4 being evolutionarily conserved and predominant in most tissues. While previous studies have implicated Calcineurin B homologous protein 1 (CHP1) as a cofactor for GPAT4, the broader role of CHP1 in regulating microsomal GPATs and TAG biosynthesis remains unclear. Here, we demonstrate that CHP1 is a critical regulator of both GPAT3 and GPAT4, essential for their stability, enzymatic activity, and lipid …
