Apathy, or loss of motivation, is a prominent syndrome accompanying both Alzheimer's and Parkinson's diseases, in addition to other disorders. One approach to understanding motivational loss is to examine the processes underlying goal-directed behaviour. Weighing up rewarding outcomes against the effort costs required to obtain them (effort-based decision-making) is a core computation when deciding to act for outcomes. Although a growing body of evidence points to disruption of this computation in people with apathy, which underlying decision parameters drive this disruption, their neural associations and whether these would generalize or differ across brain disorders have not been examined. People with …

Despite effective lipid-lowering therapies, atherosclerosis continues to be a leading cause of death, with considerable residual cardiovascular risk. Atherosclerotic lesions develop preferentially at arterial regions exposed to disturbed flow (d-flow), which induces genomic stress, endothelial injury, and barrier dysfunction. Hemodynamic forces are known to reprogram endothelial metabolism, but the role of de novo purine synthesis (DNPS), which supplies nucleotides for genome maintenance and whose terminal steps are catalyzed by the bifunctional enzyme ATIC, remains undefined in atherosclerosis. By integrating bulk and single-cell multiomics with in vitro flow systems and in vivo models, we show that d-flow upregulates DNPS and ATIC …

Alzheimer's disease (AD) is a prevalent degenerative neurological disorder with limited treatment options. Prior studies reported specific metabolites and inflammatory proteins to be related to AD risk. However, the intricate relationship between inflammatory proteins, blood metabolites, and AD risk in European population remains unclear. Genetic instruments for 1,091 metabolites and 736 inflammatory proteins were derived from two recent comprehensive genome-wide association studies. Univariable Mendelian Randomization was employed to assess potential causal effects of metabolites on AD risk, potential effects of inflammatory proteins on metabolites, and effects of inflammatory proteins on AD risk. Multivariable MR (MVMR) was further applied to disentangle …

Syrah: A Pipeline To Maximize Spatial Transcriptomics Data Output, Carolyn Brewster, Frederick G Mann, Blair Benham-Pyle, Alejandro Sánchez Alvarado

Faculty, Staff and Students Publications

Spatial analysis of gene expression patterns has been a key technique for revealing the potential functions of genes. Traditionally, these analyses conducted using in-situ hybridizations and other labor-intensive protocols were constrained to examining only a few candidate genes per sample. However, the advent of spatial transcriptomic techniques like Slide-seqV2 has transformed this field, enabling massively parallel exploration of gene expression patterns within their tissue contexts by pairing spatial locations with RNA sequencing. Despite its potential, Slide-seqV2 datasets often produce fewer usable reads than expected. We have identified that a significant source of errors in the technology stems from the chemical …

Background: Ependymoma (EPN) is the third most common pediatric brain tumor with no targeted therapies available to patients. In supratentorial ependymoma, the most frequent driver alteration is a gene fusion between ZFTA and RELA (denoted ZR), leads to constitutive localization of ZR in the nucleus. Because ZR is not currently druggable, we tested whether ZR expression leads to aberrant protein interactions that could represent therapeutic vulnerabilities.

Methods: Using CRISPR-Cas9 pooled screening, we identified many novel druggable ZR interacting proteins including XPO1, CARM1, SMARCA4, and CDK1. We focused on the nuclear export protein (XPO1), given the ability of most XPO1 inhibitors …

Tractor Workflow: A Scalable Nextflow Framework For Local Ancestry-Aware Genome-Wide Association Studies, Nirav N Shah, Taotao Tan, Jessica Honorato-Mauer, Yi-Sian Lin, Adam X Maihofer, Clement C Zai, Pgc-Ptsd Ancestry Working Group, Marcos Santoro, Caroline M Nievergelt, Elizabeth G Atkinson

Faculty, Staff and Students Publications

Motivation: The routine exclusion of admixed individuals from traditional genome-wide association studies (GWAS) due to concerns about spurious associations has limited multi-ancestry genetic discovery. Tractor addresses this issue by incorporating local ancestry into association testing, enabling the identification of ancestry-enriched signals and generating ancestry-specific summary statistics. However, adoption has been constrained by the complexity of prerequisite steps, including phasing and local ancestry inference, which require substantial bioinformatics expertise and introduce key analytical decision points.

Results: We developed a scalable, automated Nextflow workflow that integrates phasing, local ancestry inference, and Tractor association testing into a reproducible end-to-end pipeline. To demonstrate its …

Experiences Of Discrimination, Paternal Support, And Hypertensive Disorders Of Pregnancy (Hdp) In The Miehr Study, Houston, Texas, Tahereh Alinia, Elaine Symanski, Juan Manuel Alvarez, Kristina Walker Whitworth

Faculty, Staff and Students Publications

Background: Discrimination is a psychosocial stressor that, through activation of stress-response pathways, may influence risk of adverse perinatal health outcomes. However, few studies have evaluated the association between discrimination and hypertensive disorders of pregnancy (HDP), and none have explored effect modification by race or paternal support, which may buffer the adverse effects of discrimination.

Methods: We included 1,847 non-Hispanic Black and White participants from the Maternal and Infant Environmental Health Riskscape (MIEHR) study. Krieger's validated Experiences of Discrimination (EOD) scale was used to assess occurrence (yes/no) and frequency (once, 2-3, ≥ 4 times) of discrimination in nine situations. We created …

Noncanonical Clock Regulators Control Stress Responses In Digestive Diseases, Dishu Zhou, Roberto E López-Valiente, Samer G Mattar, Dongyin Guan

Faculty, Staff and Students Publications

The digestive system is essential for nutrient absorption, processing, and waste elimination. The expression of many genes and physiological processes within this system exhibits a 24-h rhythmicity. However, modern lifestyle factors, such as jet lag, shift work, and irregular eating patterns, significantly disrupt these rhythms, triggering various stress responses and contributing to numerous digestive disorders. Here, we focus on emerging studies on noncanonical clock regulators involved in stress responses, integrate these novel findings into the established model of the core circadian clock, and highlight recent advances in the development of novel therapeutics targeting these 24-h regulators. In addition, we discuss …

Introduction: Rare, deleterious germline variants are key contributors to inherited lung cancer (LC) risk. The Genetic Epidemiology of LC Consortium (GELCC) has curated valuable high-risk LC families and is uniquely positioned to uncover rare, high-penetrance variants underlying familial LC (FLC).

Methods: We performed whole-genome and exome sequencing on germline DNA from 120 high-risk LC families (177 FLC cases, 309 unaffected relatives). We prioritized rare (allele frequency < 1% in the genome aggregation database), potentially deleterious variants present in two or more FLC cases. These variants were then validated in 10,085 sporadic LC (SLC) cases and 612,970 controls.

Results: We identified 118 candidate variants, 28 of which were validated in SLC with strong statistical support. We discovered a novel pathogenic axis of three truncating variants in GALNT6, MUC4, and ERBB3 genes, which …

Background: Pediatric acute lymphoblastic leukemia (ALL) is the most common cancer in children, and its incidence and outcomes vary by race and ethnicity.

Methods: The Reducing Ethnic Disparities in Acute Leukemia (REDIAL) Consortium has assembled a cohort of patients < 25 years at diagnosis to examine genetic and neighborhood-level factors influencing ALL. As the cohort is ongoing, for this report, we examined sociodemographic and cytogenetic factors that might be associated with ALL outcome disparities.

Results: Among 2,512 patients diagnosed between 2005 and 2020, we observed distinct patterns of genetic ancestry and residential characteristics across self-reported race and ethnicity. Latino children, who comprised 55.3% of the cohort, had a mean Amerindigenous ancestry proportion of 50.9%, whereas non-Latino White children exhibited a predominantly European ancestry (mean = 78%). Neighborhood-level analysis revealed significant socioeconomic and geographic differences by …

Dolutegravir Developmental Toxicity Is Mitigated By Magnesium And Folate In Zebrafish Embryos, Robert M Cabrera, Ahmed Mohamed, Ryoko Minowa, Katheryn A Neugebauer, Daniel A Gorelick

Faculty, Staff and Students Publications

Integrase strand transfer inhibitors have transformed human immunodeficiency virus (HIV) therapy, yet the widely prescribed drug dolutegravir (DTG) has been linked to developmental toxicity, and its teratogenic mechanism remains unclear. Here, we used zebrafish to dissect DTG toxicity during early vertebrate development. DTG exposure from 2-4 h post-fertilization (hpf) to 24 hpf produced high mortality and abnormal morphology. Co-treatment with folates partially restored normal morphology, whereas calcium had no effect. Strikingly, supplementation with magnesium (Mg) partially rescued DTG-exposed embryos, implicating Mg availability in protection. In competitive binding assays, Mg increased binding of folate to purified folate receptor (FOLR1) by 30% …

Adhesion G protein-coupled receptors (aGPCRs) constitute a structurally and functionally distinct group within the superfamily of GPCRs. In 2015, the International Union of Pharmacology invited the Adhesion GPCR Consortium to publish a comprehensive review about aGPCRs and establish a unified nomenclature. Since then, substantial progress has been made in delineating the biological roles, molecular architecture, biochemical properties, expression profiles, ligand repertoire, and activation and signaling strategies of aGPCRs. Commensurate with these advances, their relevance to human pathophysiology has become increasingly apparent. In a coordinated effort, the Adhesion GPCR Consortium has reviewed recent progress in this field and provides a comprehensive …

Background: Relapsed medulloblastoma remains a significant therapeutic challenge as it is near universally fatal. The tumor microenvironment of medulloblastoma plays a critical role in tumor progression, influencing tumor growth, immune evasion, and therapeutic resistance. We hypothesized that defining tumor-immune interactions in diagnostic and relapsed medulloblastoma may uncover mechanisms of immune evasion and identify novel therapeutic targets.

Methods: We analyzed paired primary and recurrent RNA-sequencing data from 140 medulloblastoma patients to profile immune cell composition and validate spatial relationships within the TME. To identify key tumor-immune interactions, we developed a novel algorithm to detect receptor-ligand pairs using single-cell RNA-sequencing data. These …
