Clonal hematopoiesis (CH) is defined by the expansion of a lineage of genetically identical cells in blood. Genetic lesions that confer a fitness advantage, such as leukemogenic point mutations or mosaic chromosomal alterations (mCAs), are frequent mediators of CH. However, recent analyses of both single cell-derived colonies of hematopoietic cells and population sequencing cohorts have revealed CH frequently occurs in the absence of known driver genetic lesions. To characterize CH without known driver genetic lesions, we use 51,399 deeply sequenced whole genomes from the NHLBI TOPMed sequencing initiative to perform simultaneous germline and somatic mutation analyses among individuals without leukemogenic …

Asymptomatic individuals with pathogenic variants in OTC, the gene encoding ornithine transcarbamylase are increasingly being identified through cascade testing, carrier screening, or as secondary findings from genome-wide sequencing tests. However, guidance for counseling and management of such individuals is currently lacking. We selected two common OTC variants for phenotypic and functional characterization: NM_000531.6:c.118C>T p.(Arg40Cys) and NM_000531.6:c.1061T>G p.(Phe354Cys). The former is the most frequently reported pathogenic/likely pathogenic missense variant present in gnomAD, and the latter has been frequently encountered in our clinical practice. We performed a retrospective chart review at our center, queried the database of the Urea Cycle …

Internet Journal of Allied Health Sciences and Practice

Purpose: Paramedics often attend to patients presenting with a mental illness, however research suggests paramedics have difficulties when attending to this patient cohort. Conversely, clinical psychologists receive training that focuses on developing strong therapeutic relationships with their patients through the use of empathy. As research has highlighted that paramedic students are known to demonstrate low levels of empathy, this study aimed to investigate the utility of two education methods used in clinical psychology training, didactic teaching and deliberate practice (DP), to develop the skill of empathy in paramedic students. Method: Students currently enrolled in an Australian paramedic university degree were …

Cerebellar Dysfunction In Glaucoma Patients, Anisha Kasi, Ji Won Bang, Vivek Trivedi, Jeannie Au, Ian Conner, Gadi Wollstein, Joel Schuman, Rakie Cham, Kevin Chan

Wills Eye Hospital Papers

Glaucoma patients often have higher injurious fall rates compared to healthy older adults. However, little is known about the underlying neural mechanisms. Recent evidence shows cerebral changes beyond the visual pathway of glaucoma patients, yet it remains unclear whether the cerebellum, which plays an important role in balance and motor control, is involved in glaucoma. In this study, we sought to investigate cerebellar functional connectivity changes in glaucoma by comparing 32 glaucoma subjects and 10 age-matched healthy control subjects who underwent resting-state functional magnetic resonance imaging at 3 Tesla with eyes closed. After conducting both regions-of-interest and seed-to-voxel analyses, we …

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 …

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. …

Children living with HIV (CLWH) are at high risk of colonization and infection by respiratory pathogens, though this risk can be reduced by other microbes in the upper respiratory microbiome. The impact of HIV infection on the pediatric upper respiratory microbiome is poorly understood, and we sought to address this knowledge gap by identifying associations between HIV infection and the nasopharyngeal microbiomes of Batswana children. We enrolled Batswana CLWH (< 5 years) and age- and sex-matched HIV-exposed, uninfected and HIV-unexposed, uninfected children in a cross-sectional study. We used shotgun metagenomic sequencing to compare nasopharyngeal microbiomes by HIV status. Among the 143 children in this study, HIV and HIV-associated immunosuppression were associated with alterations in nasopharyngeal microbiome composition, including lower abundances of Corynebacterium species associated with resistance to bacterial pathogen colonization. These findings suggest that the upper respiratory microbiome may contribute to the high risk of respiratory infections among CLWH.

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 …

Stereoelectroencephalography Reveals Neural Signatures Of Multisensory Integration In The Human Superior Temporal Sulcus During Audiovisual Speech Perception, Yue Zhang, John F Magnotti, Xiang Zhang, Zhengjia Wang, Yingjia Yu, Kathryn A Davis, Sameer A Sheth, H Isaac Chen, Daniel Yoshor, Michael S Beauchamp

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 …

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 …

Neoadjuvant chemotherapy (NAC) is a critical component of breast cancer treatment, but the molecular mechanisms underlying resistance remain poorly understood. This study aimed to identify transcriptomic changes associated with NAC resistance across four breast cancer subtypes: Luminal A, Luminal B/HER2-positive, Luminal B/HER2-negative, and Triple-Negative Breast Cancer (TNBC). RNA-seq analysis was performed on paired pre- and post-NAC breast cancer samples from 32 nonresponders. Differentially expressed genes (DEGs) were identified, and functional enrichment analyses were conducted. Protein-protein interaction (PPI) networks were constructed to identify hub genes. Tumor microenvironment (TME) infiltration was estimated using deconvolution algorithms. The results revealed distinct gene expression profiles …

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 …
