Post-Translational Modification Of H2b C-Terminal Helix Regulates Nucleosome Interactions And Chromatin Signaling, Yani Zhao, Anh Nguyen, Eyla C Arteaga, Aleksandra Skrajna, Krzysztof Krajewski, Dennis Goldfarb, Robert K Mcginty

2020-Current year OA Pubs

Histone H2B contains a highly conserved C-terminal (H2B αC) helix that has been implicated in chromatin interactions and dynamics. The H2B αC helix comprising residues 105-125 is positioned adjacent to a major site of nucleosome interactions called the acidic patch. Despite individual structural studies highlighting interactions between chromatin proteins and the H2B αC helix, the general role of the helix in mediating nucleosome recognition has not been explored. Moreover, many post-translational modifications (PTMs) have been identified within the H2B αC helix, but significant gaps exist in our understanding of their regulatory potential. In this study, we employed nucleosome affinity proteomics …

Risk Of Clonal Hematopoiesis In Families Exposed To Radiation Following The Chornobyl Accident, Mitchell J Machiela, Irenaeus Chan, Kelly Bolton, Et Al.

2020-Current year OA Pubs

Radiation exposure is a well-established risk factor for leukemia. Clonal hematopoiesis (CH), the expansion of mutated hematopoietic cells, is also associated with increased leukemia risk and its frequency is higher in cancer patients following radiotherapy and chemotherapy. We investigated whether low to moderate environmental ionizing radiation determined by state-of-the-art dosimetric analysis was associated with CH in the Chornobyl Family Study (CFS). Our study conducted targeted high-depth sequencing and array genotyping to identify and characterize clonal hematopoiesis of indeterminate potential (CHIP) and mosaic chromosomal alterations (mCAs) in 882 participants from 292 CFS families. Fathers had mean bone marrow radiation doses of …

Preconditioning With Low-Dose Radiation Improves Antitumor Immunity And Survival In Dc-Vaccinated Mice, Eric Kwon, Shelby Namen, Colin J Willoughby, Solomon Kang, Gaurav Pandey, Alexander B Kim, Carl J Deselm

2020-Current year OA Pubs

Preconditioning regimens are essential for the immunologic success of cell therapies like CAR T cells. Nevertheless, their effect on cancer vaccines is underexplored, and preconditioning regimens are generally absent from cancer vaccine clinical trials. To address this knowledge gap, we evaluated the impact of various preconditioning strategies on dendritic cell (DC) vaccine efficacy in a murine tumor model. Mice bearing syngeneic tumors received preconditioning with 2 Gy low-dose radiation therapy (LD RT; whole-body or tumor-only), cyclophosphamide, paclitaxel, LD RT plus cyclophosphamide, or no preconditioning, followed by administration of antigen-loaded DCs. Whether whole-body or tumor-directed, LD RT preconditioning significantly enhanced vaccine-induced …

Handling Hemolytic Blood Samples From High-Risk Clinical Areas: A Call To Action, Alan H B Wu, Jerrold H Levy, W Franklin Peacock, Ramzy Rimawi, Manuel Sanchez Luna, Christopher Farnsworth, Hugo Stiegler, Robert H Christenson

2020-Current year OA Pubs

BACKGROUND: Spectrophotometric testing to detect sample hemolysis is available from central laboratory chemistry analyzers. While the cause and preventative measures are known, hemolysis continues to be a common preanalytical error, especially for specimens collected from the emergency department (ED) and intensive care units (ICUs) where point-of-care analyzers are commonly used for whole blood electrolyte testing. Recently, these analyzers have employed technology to detect hemolysis directly on whole blood samples.

METHODS: Experienced laboratorians and physicians from the clinical laboratory, ED, adult and neonatal ICUs provide a summary of the medical importance of in vitro hemolysis. Causes for in vivo hemolysis are …

The outflow of 'dirty' brain fluids from the glymphatic system drains via the meningeal lymphatic vessels to the lymph nodes in the neck, primarily the deep cervical lymph nodes (dcLN). However, it is unclear whether dcLN drainage is essential for normal cerebral homeostasis. Using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and computational fluid dynamics, we studied the impact of long-term mechanical stress from compromised dcLN drainage on brain solute and fluid outflow in anesthetized rats. We found that in young, but not middle-aged, rats, impairment of dcLN drainage was linked to moderately increased intracranial pressure and the emergence of extracranial …

Mepolizumab Alters Gene Regulatory Networks Of Nasal Airway Type-2 And Epithelial Inflammation In Urban Children With Asthma, Courtney L Gaberino, Michelle A Gill, Jeffrey Stokes, Et Al.

2020-Current year OA Pubs

Mepolizumab (anti-IL5 therapy) reduces asthma exacerbations in urban children with exacerbation-prone eosinophilic asthma. We previously utilized nasal transcriptomics to identify inflammatory pathways (gene co-expression modules) associated with asthma exacerbations despite this therapy. In this study, we applied differential gene correlation analysis on these targeted gene co-expression modules to gain better insight into the treatment effects on correlation structure within gene networks. Mepolizumab treatment resulted in loss of correlation amongst eosinophil-specific genes but conservation and even strengthening of correlation amongst mast cell-specific genes, T2 cytokines, and airway epithelial inflammatory genes. Notably, mepolizumab induced significant gain in correlation of genes associated with …

Inflammatory Pain In Mice Induces Light Cycle-Dependent Effects On Sleep Architecture, Dominika J Burek, Khairunisa Mohamad Ibrahim, Andrew G Hall, Ashish Sharma, Jessica A Cucinello-Ragland, Erik S Musiek, Jose A Morón, William A Carlezon Jr

2020-Current year OA Pubs

Pain syndromes include physical, sensory, emotional, and cognitive symptoms such as disability, negative affect, feelings of stress, and fatigue. Experimental induction of long-term inflammatory pain in rodents by hindpaw injection of complete Freund's adjuvant (CFA) produces anhedonia and dysregulated naturalistic behaviors, similar to the effects of unregulated stress. We examined whether these similarities extend to changes in sleep and rhythms, such as those induced by chronic social defeat stress, using actigraphy and wireless EEG in mice. Comparisons were made between groups that received injections at the onset of the light or dark phase. We found that CFA-induced inflammatory pain alters …

S1pr1 Regulates Lymphatic Valve Development And Tertiary Lymphoid Organ Formation In The Ileum, Xin Geng, Gwendalyn J Randolph, Et Al.

2020-Current year OA Pubs

Efficient lymph flow is ensured by lymphatic valves (LVs). The mechanisms that regulate LV development are incompletely understood. Here, we show that the deletion of the GPCR sphingosine 1-phosphate receptor-1 (S1PR1) from lymphatic endothelial cells (LECs) results in fewer LVs. Interestingly, LVs that remained in the terminal ileum-draining lymphatic vessels were specifically dysfunctional. Furthermore, tertiary lymphoid organs (TLOs) formed in the terminal ileum of the mutant mice. TLOs in this location are associated with ileitis in humans and mice. However, mice lacking S1PR1 did not develop obvious characteristics of ileitis. Mechanistically, S1PR1 regulates shear stress signaling and the expression of …

Acad10 And Acad11 Enable Mammalian 4-Hydroxy Acid Lipid Catabolism, Edrees H Rashan, Abigail K Bartlett, Jingying Zhang, Andrew J Smith, Zakery N Baker, Patrick Forny, Peng Yuan, David J Pagliarini, Et Al.

2020-Current year OA Pubs

Fatty acid β-oxidation is a central catabolic pathway with broad health implications. However, various fatty acids, including 4-hydroxy acids (4-HAs), are largely incompatible with β-oxidation machinery before being modified. Here we reveal that two atypical acyl-CoA dehydrogenases, ACAD10 and ACAD11, drive 4-HA catabolism in mice. Unlike other ACADs, ACAD10 and ACAD11 feature kinase domains that phosphorylate the 4-hydroxy position as a requisite step in converting 4-hydroxyacyl-CoAs into conventional 2-enoyl-CoAs. Through cryo-electron microscopy and molecular modeling, we identified an atypical dehydrogenase binding pocket capable of accommodating this phosphorylated intermediate. We further show that ACAD10 is mitochondrial and necessary for catabolizing shorter-chain …

2020-Current year OA Pubs

Acute Compartment Syndrome (ACS) is a serious medical condition that arises from increased pressure within osteofascial compartments, leading to impaired blood flow and potential tissue damage. Early and accurate diagnosis is critical for preventing permanent damage. Current methods rely largely on qualitative assessments with limited accuracy, and those that exploit invasive pressure measurements often prove inadequate. Herein, a soft materials-based multimodal sensor probe is introduced, as well as the mechanical and thermal influences to monitor intra-compartmental pressure, tissue oxygen saturation (StO

Elevated expression of prothymosin α (ProT) is frequently observed in cancers, but the underlying molecular mechanism remains poorly understood. Here, we report the clinical relevance of ProT expression and its correlation with lung cancer progression. We have shown that ProT was highly expressed in early-stage lung cancer, exhibiting nuclear localization; on the contrary, a loss of nuclear ProT expression was detected in late-stage tumor specimens. Furthermore, the expression of nuclear ProT impaired lung cancer cell migration, suppressed TGF-β-induced epithelial-to-mesenchymal transition (EMT)-associated transcription factor expression, and inhibited in vivo tumor metastasis. The suppressive effect of ProT was further found to trigger …

Nerve-Associated Macrophages Control Adipose Homeostasis Across Lifespan And Restrain Age-Related Inflammation, Elsie Gonzalez-Hurtado, Maxim N Artyomov, Et Al.

2020-Current year OA Pubs

Age-related inflammation or 'inflammaging' increases disease burden and controls lifespan. Adipose tissue macrophages (ATMs) are critical regulators of inflammaging; however, the mechanisms involved are not well understood in part because the molecular identities of niche-specific ATMs are unknown. Using intravascular labeling to exclude circulating myeloid cells followed by single-cell sequencing with orthogonal validation via multiparametric flow cytometry, we define sex-specific changes and diverse populations of resident ATMs through lifespan in mice. Aging led to depletion of vessel-associated macrophages, expansion of lipid-associated macrophages and emergence of a unique subset of CD38
