Faculty, Staff and Students Publications

Human speech perception is multisensory, integrating auditory information from the talker's voice with visual information from the talker's face. BOLD fMRI studies have implicated the superior temporal gyrus (STG) in processing auditory speech and the superior temporal sulcus (STS) in integrating auditory and visual speech, but as an indirect hemodynamic measure, fMRI is limited in its ability to track the rapid neural computations underlying speech perception. Using stereoelectroencephalography (sEEG) electrodes, we directly recorded from the STG and STS in 42 epilepsy patients (25F, 17M). Participants identified single words presented in auditory, visual, and audiovisual formats with and without added auditory …

Role Of M6a Mrna Methylation In Plant Defense, Rakesh Srivastava, Niraj Lodhi

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

N6-methyladenosine (m⁶A) is the most abundant and dynamic RNA modification in eukaryotic messenger and non-coding RNAs, playing a pivotal role in the post-transcriptional regulation of gene expression. The coordinated actions of m⁶A writers, erasers, and readers influence transcript stability, immune activation, and pathogen suppression. Growing evidence indicates that m⁶A fine-tunes the expression of defense-related genes, modulates RNA processing events, and is frequently hijacked by pathogens and pests to promote virulence. Notably, the dual role of m⁶A in enhancing plant defense and facilitating pathogen adaptation highlights its significance in the host–pathogen arms race. …

Purpose: Purine metabolism is a promising therapeutic target in cancer; however, how cancer cells respond to purine shortage, particularly their adaptation and vulnerabilities, remains unclear.

Experimental design: Using the recently developed purine shortage-inducing prodrug DRP-104 and genetic approaches, we investigated the responses in prostate, lung, and glioma cancer models.

Results: We demonstrate that when de novo purine biosynthesis is compromised, cancer cells employ microtubules to assemble purinosomes, multiprotein complexes of de novo purine biosynthesis enzymes that enhance purine biosynthesis efficiency. Although this process enables tumor cells to adapt to purine shortage stress, it also renders them more susceptible to the …

Patients with non–small cell lung cancer (NSCLC) with loss of the tumor suppressor gene STK11 are resistant to immune checkpoint therapies like anti–PD-1. In this study, we conducted an in vivo CRISPR screen that identified histone deacetylase 1 as a target to reverse anti–PD-1 resistance driven by loss of STK11 and developed TNG260, a potent small-molecule inhibitor of the CoREST complex with selectivity exceeding previously generated inhibitors in this class in preclinical studies. Treatment with TNG260 led to increased expression of immunomodulatory genes in STK11-deficient cancer cells. When combined with anti–PD-1, TNG260 induced immune-mediated stasis and/or regression in STK11 …

When operating on gliomas near critical language regions, surgeons risk either leaving residual tumor or inducing permanent postoperative language deficits (PLDs). Despite the advent of intraoperative mapping techniques, subjective judgments frequently determine important surgical decisions. We aim to inform data-driven surgery by constructing a non-invasive mapping approach that quantitatively predicts the impact of individual surgical decisions on long-term language function. This study included 79 consecutive patients undergoing resection of language-eloquent gliomas. Patients underwent preoperative navigated transcranial magnetic stimulation (TMS) language mapping to identify language-positive sites ("TMS points") and their associated white matter tracts ("TMS tracts") as well as formal language …

Journal of the Saudi Heart Association

Introduction: Coronary artery ectasia (CAE) is defined as abnormal dilatation of coronary arteries and may be linked to subclinical myocardial dysfunction. Conventional echocardiographic parameters may not adequately detect early left ventricular (LV) dysfunction. Two-dimensional speckle-tracking echocardiography (2D STE) has shown promise in identifying subtle myocardial changes.

Methods: In this single-center observational study, 90 participants with available coronary angiography were divided into three groups: Group A (controls, n=30), Group B (single-vessel CAE, n=30), and Group C (multi-vessel CAE, n=30). Standard echocardiographic indices including LV ejection fraction (LVEF), volumes, and diastolic function were assessed. Global radial, longitudinal, circumferential, and area strains were …

RAS pathway (RASp) mutations induce proliferative features, and promote transformation in chronic myelomonocytic leukemia (CMML). However, the unique clonal landscape and hierarchy of distinct RASp mutations remain unexplored. To characterize the landscape, architecture, and implications of unique RASp mutations in CMML, we evaluated a cohort of 814 patients with CMML. We identified 461 RASp mutations among 342 patients (42%). N/KRAS and CBL mutations were the most common, frequently involved the P-loop or RING domains, respectively, and frequently appeared as dominant events (63% and 65%, respectively). BRAF, NF1, and PTPN11 mutations spanned throughout the gene structure, and frequently appeared as subclonal …

Optimizing Genetic Ancestry Adjustment In Dna Methylation Studies: A Comparative Analysis Of Approaches, Kira D Höffler, Seyma Katrinli, Matthew W Halvorsen, Anne-Kristin Stavrum, Kevin S O'Connell, Alexey Shadrin, Srdjan Djurovic, Ole A Andreassen, James J Crowley, Jan Haavik, Kristen Hagen, Gerd Kvale, Kerry Ressler, Bjarne Hansen, Jair C Soares, Gabriel R Fries, Alicia K Smith, Stéphanie Le Hellard

Faculty, Staff and Student Publications

Background: Genetic ancestry is an important factor to account for in DNA methylation studies because genetic variation influences DNA methylation patterns. One approach uses principal components (PCs) calculated from CpG sites that overlap with common SNPs to adjust for ancestry when genotyping data is not available. However, this method does not remove technical and biological variations, such as sex and age, prior to calculating the PCs. The first PC is therefore often associated with factors other than ancestry.

Methods: We developed and adapted the adapted EpiAnceR+ approach, which includes (1) residualizing the CpG data overlapping with common SNPs for control …

Nongenetic transcription evolution has been increasingly explored and recognized to drive tumor cell progression and therapeutic resistance. As the regulation hub of transcription machinery, cyclin-dependent kinase 9 (CDK9) is the gatekeeper of RNA polymerase II transcription, and CDK9 dysfunction results in transcriptomic reprogramming and tumor cell progression. We recently reported that the heat shock protein 90 (HSP90)-MYC-CDK9 network drives therapeutic resistance in mantle cell lymphoma (MCL) through transcriptomic reprogramming. We also showed that targeting CDK9 by AZD4573 and enitociclib is a safe and effective treatment in preclinical Mantle Cell Lymphoma (MCL) models, supporting CDK9 as a valid therapeutic target for …
