Vascular calcification (VC), a common complication associated with diabetes mellitus (DM), substantially increases the risk of cardiovascular diseases and is associated with elevated mortality in individuals with DM. Endothelial-to-mesenchymal transition (EndMT) imparts phenotypic plasticity to vascular endothelial cells (VECs), granting them the potential for osteogenic differentiation, which is a crucial mechanism in regulating VC. Notably, adenosine-ADORA2A-mediated endothelial dysfunction plays a pivotal regulatory role in cardiovascular diseases. However, the specific role of endothelial ADORA2A in diabetic VC remains to be elucidated. In this study, we found that ADORA2A was upregulated in the endothelium of diabetic mice and cultured human aortic endothelial …

Metabolic plasticity allows cancer cells to survive under adverse conditions. To investigate the role of mitochondrial chaperone tumor necrosis factor receptor-associated protein 1 (TRAP1) in this process, we used CRISPR/Cas9 mediated genetic deletion to knock out (KO) TRAP1 in colon cancer cells. Depletion of TRAP1 triggered a series of events: induced metabolic reprogramming, increased glycolytic flux, downregulation of mitochondrial complex I, and elevated ROS generation. TRAP1-deficient cells showed tolerance to Oxidative Phosphorylation (OXPHOS) inhibitors and exhibited a higher extracellular acidification rate (ECAR). Additionally, TRAP1 depletion activated hypoxia response elements (HREs) and upregulated HIF1A target genes such as GLUT1 and MCT1. …

RNA modification, which is evolutionarily conserved, is crucial for modulating various biological functions and disease pathogenesis. High resolution transcriptome-wide mapping of RNA modifications has facilitated both data resources and computational prediction of RNA modification. While these prediction algorithms are promising, they are limited in interpretability or generalizability, or the capacity for discovering novel post-transcriptional regulations. Here, we present NetRNApan, a deep learning framework for RNA modification site prediction, motif discovery and trans-regulatory factor identification. Using m5U profiles generated by FICC-seq and miCLIP-seq technologies and single-base resolution m6A sites from multiple experiments as cases, we demonstrated the accuracy of NetRNApan with …

Gliomas and brain metastases are associated with poor prognosis, necessitating a deeper understanding of brain tumor biology and the development of effective therapeutic strategies. Although our group and others have demonstrated microbial presence in various tumors, recent controversies regarding cancer-type-specific intratumoral microbiota emphasize the importance of rigorous, orthogonal validation. This prospective, multi-institutional study included a total of 243 samples from 221 patients, comprising 168 glioma and brain metastases samples and 75 non-cancerous or tumor-adjacent tissues. Using stringent fluorescence in situ hybridization, immunohistochemistry and high-resolution spatial imaging, we detected intracellular bacterial 16S rRNA and lipopolysaccharides in both glioma and brain metastases …

Predictors Of Response To Emergent Therapies In Paediatric Immune Thrombocytopenia, Candelaria O'Farrell, Taylor M Luckie, Matthew J Willis, Susan E Kirk, Brandon R Lucari, Michael E Scheurer, Xiaotian Gao, Amanda B Grimes

Faculty, Staff and Students Publications

Emergent therapies (ET), which include intravenous immunoglobulin (IVIG), corticosteroids and intravenous anti‐Rho(D) immunoglobulin, are used to treat acute episodes of bleeding in children with immune thrombocytopenia (ITP). There are currently no known biomarkers or clinical features predictive of treatment response to any specific ET. Thus, the treatment of ITP remains largely trial and error, exposing patients to potentially ineffective medications, which are often expensive and associated with adverse effects. We therefore sought to identify the predictors of treatment response through comparison of clinical characteristics in paediatric patients with ITP responsive to ET versus those non‐responsive to ET. We identified high …

Recognition of foreign RNA is critical for the innate immune response to viruses. Interferon (IFN)-induced proteins with tetratricopeptide repeats (IFIT) 2 and 3 are highly upregulated following viral infection, but mechanistic insight into their antiviral role is lacking. Here we demonstrate that short 5' untranslated regions (UTRs), a characteristic of many viral mRNAs, can serve as a molecular pattern for innate immune recognition via IFIT2 and IFIT3. Structure determination of the IFIT2-IFIT3 complex at 3.2 Å using cryo-EM reveals a domain-swapped heterodimer that is required for recognition of the viral mRNA 5' end, translation inhibition and antiviral activity. Critically, viral …

Reprogrammed Glucose Metabolism In Vascular Smooth Muscle Cells And Its Implications For Vascular Diseases, Qian Ma, Yongfeng Cai, Qiuhua Yang, Wendy Zhang, Suowen Xu, Yuqing Huo

Geroscience aims to target the aging process to extend healthspan. However, even isogenic individuals show heterogeneity in natural aging rate and responsiveness to pro-longevity interventions, limiting translational potential. Using RNAseq analysis of young, isogenic, subpopulations of Caenorhabditis elegans selected solely on the basis of the splicing pattern of an in vivo minigene reporter that is predictive of future life expectancy, we find a strong correlation in young animals between predicted life span and alternative splicing of mRNAs related to lipid metabolism. The activity of two RNA splicing factors, Reversed Polarity-1 (REPO-1) and Splicing Factor 1 (SFA-1), early in life is …

Background: Radiation oncology residents report a lack of understanding and confidence in assessing radiotherapy plan quality. A contributing factor is the environment in which plan review is taught during residency, that is, routine clinical practice, which does not provide ample time for self-guided practice in a low-stakes setting. Expertise in plan review requires diverse case presentation and many examples, which are often not achievable in smaller programs and for less common cancer types. As plan quality affects patient outcomes, it is important to address these pitfalls in the education of residents on plan review.

Purpose: To address the identified pitfalls …

Background: Lymphangiogenesis, the formation of new lymphatic vessels, is primarily driven by VEGF-C-mediated activation of VEGFR-3 and plays a critical role in immune regulation and tissue repair. Although lymphangiogenesis has been well documented in various inflamed tissues, its occurrence and spatiotemporal characteristics in the olfactory mucosa during nasal inflammation remain poorly understood. To address this, we investigated the localization and development of lymphatic vessels in a mouse model of both acute and chronic nasal inflammation.

Methods: Acute inflammation was induced by intranasal administration of lipopolysaccharide (LPS; 10 μg per nostril) in 8-week-old male mice, with saline-treated mice as controls. Behavioral …

Advances in the prognostication, monitoring, and treatment of both the acute and chronic leukemias have led to drastically improved outcomes over the past 2 decades. With the advent of targeted therapies, including antibodies such as blinatumomab and inotuzumab and small molecule inhibitors, such as the BCR::ABL1 tyrosine kinase inhibitors, Bruton tyrosine kinase inhibitors, and venetoclax, the treatment landscape of leukemia has drastically changed, improving survival outcomes while relying less on overall chemotherapy intensity in many leukemia types. This progress has allowed the categorization of more leukemia types as favorable (i.e., chronic lymphocytic leukemia, younger acute lymphoblastic leukemia [patients younger than …

Brain-Wide Patterns Of Crf Receptor 1 Expression In The Transgenic Crfr1-Cre-2a-Tdtom Rat, Douglas S Engelke, Lierni Ugartemendia, Jonathan Tao, Shivakumar Rajamanikam, Fabricio H Do Monte, Nicholas J Justice

Faculty, Staff and Student Publications

The ability to manipulate neurons that express corticotropin-releasing factor (CRF) or its receptors has led to many new discoveries about how CRF signaling modulates stress-related behaviors in mice. However, similar advances in rats have been limited by the lack of reporter lines targeting CRF receptors, restricting access to behavioral paradigms that are more suitable for, or specific to, rats. Here, we provide an extensive neuroanatomical characterization of a recently generated CRFR1-Cre rat. We show that Cre and tdTomato are expressed in a pattern that closely aligns with previously reported CRFR1 expression patterns, as determined by in situ hybridization in rats …

Immune checkpoint inhibitors (ICIs) extend survival in many patients with cancer but are ineffective in patients without pre-existing immunity1–9. Although personalized mRNA cancer vaccines sensitize tumours to ICIs by directing immune attacks against preselected antigens, personalized vaccines are limited by complex and time-intensive manufacturing processes10–14. Here we show that mRNA vaccines targeting SARS-CoV-2 also sensitize tumours to ICIs. In preclinical models, SARS-CoV-2 mRNA vaccines led to a substantial increase in type I interferon, enabling innate immune cells to prime CD8+ T cells that target tumour-associated antigens. Concomitant ICI treatment is required for …

Protein Kinase Giα Oxidation Negatively Regulates Antibody Production By B Cells, Hyun-Ju Cho, Rebecca L Charles, Oleksandra Prysyazhna, Sapna Arjun, Asvi A Francois, Kevin M Mcbride, Philip Eaton

Faculty, Staff and Student Publications

Endogenous oxidants induce a C42-dependent interprotein disulfide between the subunits of protein kinase G (PKG) Iα in cardiovascular tissues to control blood pressure and ventricular relaxation during diastole. PKGIα is expressed in other cell types, including those of the immune system, where the redox state of this kinase is likely to regulate other important physiological processes. The role of PKGIα oxidation in antibody production by B cells, which produce oxidants such as hydrogen peroxide during differentiation, was examined by comparing the immune response of oxidation-resistant C42S PKGIα knock-in (KI) mice to their wild type (WT) littermates.
