Primary testicular (PT) diffuse large B-cell lymphoma (DLBCL) is a rare and aggressive lymphoma with distinct clinical and molecular characteristics. To identify prognostic biomarkers in PT-DLBCL, in this study we analyzed DNA and RNA samples of PT-DLBCL tumors from 206 patients using next-generation sequencing platforms and assays. Genetic alteration analysis found that multiple chromosomal copy number variations (CNVs), TP53 transcript mutations with high variant allele frequency, and MCD subtype had significantly adverse prognostic effects, whereas elevated microsatellite instability had a significantly favorable prognostic effect in PT-DLBCL. Targeted RNA-seq analysis identified a PTL gene expression signature by comparing PT-DLBCL with systemic …

Spase: Spatially Resolved Pathology Scores Using Optimal Transport On Spatial Transcriptomics Data, Mohammad Nuwaisir Rahman, Mohammed Abid Abrar, Vikram Rakesh Shaw, James F Martin, M Saifur Rahman, Md Abul Hassan Samee

Faculty, Staff and Students Publications

Pathological events often impact tissue regions in a spatial variable manner, making it challenging to identify therapeutic targets. Spatial transcriptomics (ST) is a powerful technology to map spatially variable molecular mechanisms, yet suitable analytical methods have been lacking. We introduce SPaSE (Spatially-resolved Pathology ScorE), an optimal transport-based algorithm to compare ST data from diseased and control tissues. SPaSE computes a “pathology score” for each spot in the diseased sample, quantifying the pathological impact at that spot. In post-MI (myocardial infarction) mouse hearts, these scores delineated zones that matched independent expert annotations. Modeling pathology scores from gene expression revealed signatures predictive …

Identification Of Functional Non-Coding Variants Associated With Orofacial Cleft, Priyanka Kumari, Ryan Z Friedman, Michael A White, Barak A Cohen, Et Al.

Oral facial cleft (OFC) comprises cleft lip with or without cleft palate (CL/P) or cleft palate only. Genome wide association studies (GWAS) of isolated OFC have identified common single nucleotide polymorphisms (SNPs) in many genomic loci where the presumed effector gene (for example, IRF6 in the 1q32 locus) is expressed in embryonic oral epithelium. To identify candidates for functional SNPs at eight such loci we conduct a massively parallel reporter assay in a fetal oral epithelial cell line, revealing SNPs with allele-specific effects on enhancer activity. We filter these SNPs against chromatin-mark evidence of enhancers and test a subset in …

The integrated stress response (ISR) is an adaptive pathway hijacked by cancer cells to survive cellular stresses in the tumor microenvironment. ISR activation potently induces PD-L1, leading to suppression of antitumor immunity. In this study, we sought to uncover additional immune checkpoint proteins regulated by the ISR to elucidate mechanisms of tumor immune escape. The ISR coordinately induced cluster of differentiation 155 (CD155) and PD-L1, enhancing translation of both immune checkpoint proteins through bypass of inhibitory upstream open reading frames in their 5' untranslated regions. Analysis of primary human lung tumors identified a significant correlation between expression of PD-L1 and …

Diffuse midline glioma (DMG) is a devastating pediatric brain tumor. The oncolytic adenovirus Delta-24-RGD has shown promising efficacy and safety in DMG patients but is not yet curative. Thus, we hypothesized that activating dendritic cells (DCs) through the CD40 costimulatory receptor could increase antigen presentation and enhance the anti-tumor effect of the virus, resulting in long-term responses. This study shows that the intratumoral co-administration of Delta-24-RGD and a CD40 agonistic antibody is well tolerated and induces long-term anti-tumor immunity, including complete responses (up to 40%) in DMG preclinical models. Mechanistic studies revealed that this therapy increased tumor-proliferating T lymphocytes and …

A previously reported clinical trial in familial adenomatous polyposis (FAP) patients treated with erlotinib plus sulindac (ERL + SUL) highlighted immune response/interferon-γ signaling as a key pathway. In this study, we combine intermittent low-dose ERL ± SUL treatment in the polyposis in rat colon (Pirc) model with mechanistic studies on tumor-associated immune modulation. At clinically relevant doses, short-term (16 weeks) and long-term (46 weeks) ERL ± SUL administration results in near-complete tumor suppression in Pirc colon and duodenum (p < 0.0001). We identify a low-dose threshold for significant antitumor activity in Pirc rats given SUL at 125 ppm in the diet plus ERL at 5 mg/kg body weight via twice-weekly oral gavage (SUL125 + ERL5 × 2). Longitudinal analyses show diminished expression of MHC class I and II genes in polyps larger than Grade 5, a novel finding in the Pirc model. Treatment with ERL ± SUL upregulates the corresponding MHC and immune-associated factors in a subset of Pirc colon polyps, Pirc tumor cell lines, murine colon carcinoma cells, and FAP patient-derived organoids, with Nlrc5 playing a critical role in this effect. Imaging mass cytometry reveals that SUL125 + ERL5 × 2 increases tumor-associated Cd4+ T cells by ~2.6-fold (p < 0.05), with no apparent effect on Cd8+ T cells. The treatment also increases tumor-associated Cd68+ cells (p < 0.05) and decreases Foxp3+ (p < 0.01) and Arg1+ (p < 0.05) cells. Thus, intermittent low-dose ERL + SUL treatment enhances tumor-associated MHC expression and remodels the immune cell niche toward a more permissive "helper" immune microenvironment. We conclude that early immune-interception strategies targeting interferon-γ signaling may benefit FAP patients at drug doses below the clinical standard of care.

Objective: This study aimed to investigate serum metabolomic biomarkers associated with incident type 2 diabetes mellitus (T2DM) and evaluate their performance in improving T2DM risk prediction.

Methods: Untargeted proton nuclear magnetic resonance (1H NMR) spectroscopy-based metabolomics analyses were conducted in the Multi-Ethnic Study of Atherosclerosis (MESA; n = 3460; discovery cohort) and The Rotterdam Study (RS; n = 1556; replication cohort). Multivariable cause-specific hazards models were used to analyze the associations between 23 571 serum metabolomic spectral variables and incident T2DM. Replicated metabolites required an false discovery rate-adjusted P < .01 in MESA, P < .05 in RS, and consistent direction of association. Pathway and network analyses were conducted to elucidate biological mechanisms underlying T2DM development. The utility of the replicated metabolites in improving T2DM risk prediction was assessed based on the Framingham Diabetes Risk Score. A 2-sample Mendelian randomization was conducted to assess causal associations.

Results: Nineteen metabolites were significantly associated with incident T2DM. Pathway analyses …

South Asian individuals (SA), representing approximately one quarter of the global population, experience a disproportionately high burden of cardiovascular disease. Some of this increased susceptibility is accounted for by traditional risk factors such as diabetes, hypertension, carbohydrate-rich diets, and rising rates of obesity and metabolic syndrome. However, other previously underappreciated risk factors may also play a crucial role. These include environmental pollution, genetic factors, and Lp(a) (lipoprotein(a)). Various epidemiological and genetic studies support the role of Lp(a) as a causal and independent risk factor for atherosclerotic cardiovascular disease. SA have a higher prevalence of elevated Lp(a) levels (25% have levels …

Generalising information from ourselves to others, and others to ourselves allows for both a dependable source of navigation and adaptability in interpersonal exchange. Disturbances to social development in sensitive periods can cause enduring and distressing damage to lasting healthy relationships. However, identifying the mechanisms of healthy exchange has been difficult. We introduce a theory of self-other generalisation tested with data from a three-phase social value orientation task - the Intentions Game. We involved humans with (

Respiratory syncytial virus (RSV) is a significant cause of morbidity and mortality in high-risk populations. Although prophylactic options are available, there are no effective oral therapeutics for RSV infection. Obeldesivir (ODV) is an orally bioavailable prodrug of the nucleoside analog GS-441524, which is converted intracellularly to its active nucleoside triphosphate and inhibits the RSV RNA polymerase. Here we report the potent antiviral activity of ODV against geographically and temporally diverse RSV A and B clinical isolates (EC50: 0.20–0.66 μM). Resistance selection studies with ODV and GS-441524 against RSV identify a single amino acid substitution, I777L, in the L polymerase with …

Uveal melanoma (UM) is a rare but frequently metastasizing cancer. Genome-wide association studies have identified three common genome-wide significant germline risk loci. Here, we perform a genome-wide association study on 401 new cases and conduct a meta-analysis with three independent previously published cohorts for a total sample size of 2,426 cases. We confirm the three previously identified risk loci and identify four additional genome-wide significant loci. We find that eye pigmentation-decreasing variants are systematically associated with increased UM risk and that selection for lighter pigmentation in the past 5,000 years explains about 73% of the difference in UM incidence between …

Integrase-Deficient Lentiviral Vector As A Platform For Efficient Crispr/Cas9-Mediated Gene Editing For Mucopolysaccharidosis Iva, Fnu Nidhi, Shunji Tomatsu

Department of Pediatrics Faculty Papers

Mucopolysaccharidosis IVA (MPS IVA) is a lysosomal storage disorder causing systemic skeletal dysplasia due to a deficiency of N-acetyl-galactosamine-6-sulfate sulfatase (GALNS) enzyme activity, leading to the impaired degradation and accumulation of glycosaminoglycans (GAGs), keratan sulfate (KS) and chondroitin-6-sulfate. While treatments such as enzyme replacement therapy (ERT) and hematopoietic stem cell transplantation (HSCT) are available, they have significant limitations regarding efficacy in skeletal tissues and long-term safety, highlighting the need for more effective therapies. We evaluated a novel gene therapy approach using a dual Integrase-deficient lentiviral vector (IDLV) to deliver an expression cassette that includes human GALNS cDNA and Cas9 sgRNA, …

The CREBBP lysine acetyltransferase (KAT) is frequently mutated in follicular lymphoma and diffuse large B-cell lymphoma and has been studied using gene knockout in murine and human cells. However, most CREBBP mutations encode amino acid substitutions within the catalytic KAT domain (CREBBP KAT-PM) that retain an inactive protein and have not been extensively characterized. Using CRISPR gene editing and extensive epigenomic characterization of lymphoma cell lines, we found that CREBBP KAT-PM lead to unloading of CREBBP from chromatin, loss of enhancer acetylation, and prevention of EP300 compensation. These enhancers were enriched for those that are dynamically loaded by CREBBP in …

Research on the neural basis of major depressive disorder suggests that it is fundamentally a disease of cortical disinhibition, where breakdowns of inhibitory neuronal systems lead to diminished emotion regulation and intrusive rumination. Subregions of the prefrontal cortex are thought to be sources of this disinhibition. However, due to limited opportunities for intracranial recordings from humans with major depression, this hypothesis has not been directly tested. Here, we use intracranial recordings from the dorsolateral prefrontal, orbitofrontal, and anterior cingulate cortices from patients with major depression to measure daily fluctuations in self-reported depression symptom severity. Results indicate that directed connectivity within …

Both neuronal and peripheral tissues become disrupted in Alzheimer's disease (AD). However, a comprehensive understanding of how AD impacts different tissues across the whole organism is lacking. Using Drosophila, we generated an AD Fly Cell Atlas (AD-FCA) based on whole-organism single-nucleus transcriptomes of 219 cell types from flies expressing AD-associated proteins, either human amyloid-β 42 peptide (Aβ42) or Tau, in neurons. We found that Aβ42 primarily affects the nervous system, including sensory neurons, while Tau induces accelerated aging in peripheral tissues. We identified a neuronal cluster enriched in Aβ42 flies, which has high lactate dehydrogenase (LDH) expression. This LDH-high cluster …

Errors in chromosome segregation during gametogenesis, such as nondisjunction (NDJ) errors, have severe consequences in human reproduction, and a better understanding of their etiology is of fundamental interest in genetics. Mapping NDJ errors to meiotic/mitotic stages typically requires proband-parent comparison, limiting its applicability. Herein, we develop Mis-segregation Error Identification through Hidden Markov Models (MeiHMM), a method for inferring NDJ error stage and crossover events based on only genomic data of trisomic probands. Guided by triallelic genotype/haplotype configurations, MeiHMM discerns the allelic origin at each locus, which informs NDJ error during gamete formation, without identifying the parental origin of the trisomy. …

There is an emerging role for stimulator of interferon genes (STING) signaling in pulmonary hypertension (PH) development. Related to this, prior research has demonstrated the relevance of immune checkpoint protein programmed death ligand 1 (PD-L1) expression by immunoregulatory myeloid cells in PH. However, there remains a need to elucidate the cell-specific role of STING expression, and the STING/PD-L1 signaling axis in PH, before readily available disease-modifying therapies can be applied for patients with the disease. Here, through generation of bone marrow chimeric mice, we show that STING-/- mice receiving WT bone marrow were protected against PH secondary to chronic hypoxia. …

The action-mode network (AMN) is a canonical functional brain network first identified using resting-state functional connectivity (RSFC). Based on animal and human data, we have proposed that AMN supports the brain's action mode by controlling functions required for successful goal-directed behavior. However, task fMRI averaged across groups has associated AMN regions with a variety of behaviors, contributing to uncertainty about AMN function. Here, we investigated the AMN using an inside-out approach, in which the network architecture of the AMN is first precisely mapped within individuals and then associated with behavioral functions. Individual-specific precision functional mapping with >5 h of RSFC …

CD16A is an activating Fc receptor on NK cells that mediates antibody-dependent cellular cytotoxicity (ADCC), a key mechanism in antiviral immunity. However, the role of NK cell-mediated ADCC in SARS-CoV-2 infection remains unclear, particularly whether it limits viral spread and disease severity or contributes to the immunopathogenesis of COVID-19. We hypothesized that the high-affinity CD16AV176 polymorphism influences these outcomes. Using an in vitro reporter system, we demonstrated that CD16AV176 is a more potent and sensitive activator than the common CD16AF176 allele. To assess its clinical relevance, we analyzed 1,027 patients hospitalized with COVID-19 from the Immunophenotyping Assessment in a COVID-19 …

Computational competitions are the standard for benchmarking medical image analysis algorithms, but they typically use small curated test datasets acquired at a few centers, leaving a gap to the reality of diverse multicentric patient data. To this end, the Federated Tumor Segmentation (FeTS) Challenge represents the paradigm for real-world algorithmic performance evaluation. The FeTS challenge is a competition to benchmark (i) federated learning aggregation algorithms and (ii) state-of-the-art segmentation algorithms, across multiple international sites. Weight aggregation and client selection techniques were compared using a multicentric brain tumor dataset in realistic federated learning simulations, yielding benefits for adaptive weight aggregation, and …
