Multimodal Spatial Transcriptomic Characterization Of Mouse Kidney Injury And Repair, Qiao Xuanyuan, Haojia Wu, Hemalatha Sundaramoorthi, Pierre Isnard, Changfeng Chen, Waleed Rahmani, Benjamin D Humphreys

2020-Current year OA Pubs

The transition from acute kidney injury to chronic kidney disease is characterized by significant changes in the cellular composition and molecular interactions within the kidney. Utilizing high-resolution Xenium and whole transcriptome Visium spatial transcriptomics platforms, we analyze over a million cells on 12 male mouse kidneys across six stages of renal injury and repair. We define and validate 20 major kidney cell populations and delineate distinct cellular neighborhoods through this multimodal spatial analysis. We further reveal a specific fibro-inflammatory niche enriched in failed-repair proximal tubule cells, fibroblasts, and immune cells, with conserved neighborhood gene signatures across mouse and human. Within …

Cortical Spectral Dynamics Of Vibrotactile Frequency Processing, Nabi Rustamov, Phillip Demarest, Zhuangyu Han, Safia Mohamud, Simon Haroutounian, Eric C Leuthardt

2020-Current year OA Pubs

While scientific research has extensively explored how the brain integrates touch and pain signals, the cerebral processing of specific vibrotactile frequencies remains poorly understood. This gap is particularly significant given clinical evidence that vibrotactile stimulation can reduce pain in both chronic pain patients and experimental settings. Our study investigated the cortical electrophysiological correlates of peripheral vibrotactile stimulation across different frequencies in healthy volunteers, with a focus on frequency-dependent patterns of neuronal activation. While electroencephalogram (EEG) was recorded, healthy participants received vibrotactile stimulation (high-frequency burst stimulation with different inter-burst intervals) to the left index fingertip at frequencies corresponding to established neural …

The Genetic Architecture Of Cervical Length Is Shared With Spontaneous Preterm Birth Risk, Hope M Wolf, Bradley T Webb, Jerome F Strauss 3rd, Adi L Tarca, Roberto Romero, Sonia S Hassan, Shawn J Latendresse, Tinnakorn Chaiworapongsa, Stanley Berry, Nardhy Gomez-Lopez, Piya Chaemsaithong, Timothy P York

BACKGROUND: Sonographic cervical length is a powerful predictor of maternal risk for spontaneous preterm birth (sPTB). Twin and family studies have established a maternal genetic heritability for sPTB ranging from 13 to 20%, however, there is no corresponding estimate for the heritability of mid-trimester cervical length, or an understanding of how genetic factors contribute to cervical changes across pregnancy.

METHODS: This study was based on a prospective longitudinal cohort of (N = 5,160) Black/African American women who underwent serial sonographic examination of the uterine cervix during pregnancy and were genotyped via next-generation low-pass whole genome sequencing.

RESULTS: Bivariate genetic correlations …

PURPOSE: Cancer treatment has been revolutionized by immune checkpoint inhibitors (ICI). However, a subset of patients do not respond and/or they experience significant adverse events. Attempts to integrate reliable biomarkers of ICI response as part of standard care have been hampered by limited generalizability. We previously reported our supervised machine learning (ML) model in a retrospective cohort of metastatic melanoma.

EXPERIMENTAL DESIGN: In this study, we expanded our testing to include larger cohorts of patients with melanoma accrued at several sites, including patients enrolled in clinical trials in both adjuvant and metastatic settings. We examined pretreatment hematoxylin and eosin slides …

Baby Open Brains: An Open-Source Dataset Of Infant Brain Segmentations, Eric Feczko, Dimitrios Alexopoulos, Christopher D Smyser, Et Al.

2020-Current year OA Pubs

Reproducibility of neuroimaging research on infant brain development remains limited due to highly variable processing approaches. Progress towards reproducible pipelines is limited by a lack of benchmarks such as gold-standard brain segmentations. These segmentations are limited by the difficulty of infant brain segmentations, which require extensive neuroanatomical knowledge and are time-consuming in nature. Addressing this, we constructed the Baby Open Brains (BOBs) Dataset, an open source resource of manually curated and expert reviewed infant brain segmentations. Anatomical MRI data was segmented from 71 infant imaging visits across 51 participants, using both T1w and T2w images per visit. Images showed dramatic …

Structural Insights Into Ssna1 Self-Assembly And Its Microtubule Binding For Centriole Maintenance, Lorenzo Agostini, Jason A Pfister, Nirakar Basnet, Jienyu Ding, Rui Zhang, Christian Biertümpfel, Kevin F O'Connell, Naoko Mizuno

2020-Current year OA Pubs

SSNA1 is a fibrillar protein involved in dynamic microtubule remodeling, including nucleation, co-polymerization, and microtubule branching. The underlying molecular mechanism has remained unclear due to a lack of structural information. Here, we determine the cryo-EM structure of C.elegans SSNA-1 at 4.55-Å resolution and evaluate its role in embryonic development. We find that SSNA-1 forms an anti-parallel coiled-coil, with self-assembly facilitated by an overhang of 16 C-terminal residues that form a triple-stranded helical junction. The microtubule-binding region is within the triple-stranded junction, suggesting that self-assembly of SSNA-1 creates hubs for effective microtubule interaction. Genetical analysis elucidates that SSNA-1 deletion significantly reduces …

Structural Basis For Membrane Microdomain Formation By A Human Stomatin Complex, Jack Stoner, Shufang Li, Ziao Fu

2020-Current year OA Pubs

Biological membranes are not just passive barriers-they actively sense and respond to mechanical forces, in part through specialized proteins embedded within them. Among these are Stomatin-family proteins, which are known to influence membrane stiffness and regulate ion channels, yet how they achieve these functions at the molecular level has remained elusive. Here, we report the 2.2 Å cryo-electron microscopy structure of the human Stomatin complex in a native membrane environment. We find that Stomatin assembles into a 16-subunit ring-shaped homo-oligomer, forming a ~12 nm-wide cage that defines a mechanically distinct, curvature-resistant membrane microdomain. While the majority of the complex exhibits …

[[68ga] Labelled Exendin For Radioguided Surgery Of Intrapancreatic Insulin Producing Lesions In Patients With Congenital Hyperinsulinism, Peter Kühnen, Vikas Prasad, Et Al.

2020-Current year OA Pubs

BACKGROUND: Congenital hyperinsulinism (CHI) is a life threatening disease. Localization of affected intrapancreatic beta cells responsible for focal forms during surgery can be challenging. In this study we investigated a new radioguided surgical (RGS) approach using [68Ga]Exendin to facilitate intraoperative focus detection. All patients were scanned initially with [18F]-DOPA-PET followed by [68Ga]Exendin PET to differentiate between focal and non-focal forms. Focal CHI patients were then operated. At the beginning of standard surgical dissection of the pancreas in CHI patients (n = 12), 46 MBq of [68Ga]Exendin were injected intravenously. Intrapancreatic localization of the foci was determined by using a hand-held …

Bclaf1 Restrains Stress Responses In Hematopoietic Stem Cells To Support Expansion And Repopulation, Stephanie J Crowley, Wei Yang, Lynn S White, Jun Wu, Yanan Li, Haley Schmidt, Kyunghee Choi, Jeffrey A Magee, Jeffrey J Bednarski

2020-Current year OA Pubs

Hematopoietic stem cells (HSCs) rapidly expand during fetal development and after stress. Here, we identify B-cell lymphoma-2-associated factor 1 (BCLAF1) as a regulator of HSC repopulation activity, with roles in the expansion of fetal HSCs and hematopoietic reconstitution after stem cell transplantation. Using mice with hematopoietic-specific and inducible deletion of Bclaf1, we find that BCLAF1 promotes fetal HSC development but is dispensable for the maintenance of adult HSCs at steady state. Loss of BCLAF1 in either fetal or adult HSCs significantly impairs their self-renewal and multilineage reconstitution activity after stem cell transplantation. Single-cell RNA sequencing of fetal hematopoietic progenitors reveals …

2020-Current year OA Pubs

In this study, we generated and integrated plasma proteomics and metabolomics with the genotype datasets of over 2300 European (EUR) and 400 African (AFR) ancestries to identify ancestry-specific multi-omics quantitative trait loci (QTLs). In total, we mapped 954 AFR pQTLs, 2848 EUR pQTLs, 65 AFR mQTLs, and 490 EUR mQTLs. We further applied these QTLs to ancestry-stratified type-2 diabetes (T2D) risk to pinpoint key proteins and metabolites underlying the disease-associated genetic loci. Using INTACT that combined trait-imputation and colocalization results, we nominated 270 proteins and 72 metabolites from the EUR set; seven proteins and one metabolite from the AFR set …

Assessing Buprenorphine Treatment Utilization And Samhsa Data Waiver Provider Distribution In 2021: A Real-World Analysis In California, Yun Wang, Tao Hu, Chih-Hung Chang, Matthew Heshmatipour, Jeff Jianfei Guo, Moom R Roosan, Karen A Miotto

2020-Current year OA Pubs

Qualified clinicians previously required a practitioner waiver (i.e., "DATA-waiver" or "X-waiver") to offer buprenorphine, a medication for opioid use disorder (OUD). However, many counties in the US experience fewer buprenorphine prescriptions due to factors such as "DATA-waiver" providers underutilizing their buprenorphine prescribing ability. Our study aimed to compare the availability of active buprenorphine-prescribing clinicians in California to the Substance Abuse and Mental Health Services Administration (SAMSHA)-listed DATA waived prescribers under each 5-digit ZIP Code. This study utilized the buprenorphine prescription record data in 2021 from California's Controlled Substance Utilization Review and Evaluation System (CURES). The list of the locators for …

Vaccination With Acinetobacter Baumannii Adhesin Abp2d Provides Protection Against Catheter-Associated Urinary Tract Infection, Morgan R Timm, Kevin O Tamadonfar, Taylor M Nye, Jesús Bazán Villicaña, Jerome S Pinkner, Karen W Dodson, Ali H Ellebedy, Scott J Hultgren

2020-Current year OA Pubs

Catheter-associated urinary tract infections (CAUTIs) contribute greatly to the burden of healthcare-associated infections. Acinetobacter baumannii is a Gram-negative bacterium with high levels of antibiotic resistance that is of increasing concern as a CAUTI pathogen. A. baumannii expresses fibrinogen-binding adhesins (Abp1D and Abp2D) that mediate biofilm formation on catheters, which become coated with fibrinogen upon insertion. Here we develop a protein subunit vaccine against the Abp1D and Abp2D receptor binding domains (RBD) and show that vaccination significantly reduces bacterial titers in a female mouse model of CAUTI. We further demonstrate that immunity to Abp2D

2020-Current year OA Pubs

IL-33 is a key driver of type 2 inflammation and implicated in pathology of chronic obstructive pulmonary disease (COPD) and asthma. However, the mechanism for IL-33 secretion and regulation in the context of chronic airway disease is poorly understood. We previously reported an airway disease-associated isoform IL-33Δ34 that escapes nuclear sequestration and is tonically secreted from epithelial cells. Here, we describe how this IL-33Δ34 isoform interacts with HSP70 within cells and is targeted to secretory organelles through coordinated binding to phosphatidylserine (PS) and delivered to compartments for unconventional protein secretion (CUPS). Once secreted, extracellular HSP70 (eHSP70) in complex with IL-33Δ34 …

Subsets Of Follicular Lymphoma 3b Have Divergent Outcomes: Results From The Prospective Multicenter Mer And Leo Cohorts, Patrizia Mondello, David Russler-Germain, Brad Kahl, Et Al.

2020-Current year OA Pubs

Follicular lymphoma (FL) 3B is considered an aggressive lymphoma, however recent studies have challenged this paradigm. Additional controversy involves the clinical implication of pure FL3B (FL3Bp) vs FL3B with concurrent diffuse large B cell lymphoma (DLBCL) (FL3Bc). To address these questions, we performed a pooled study of the MER and LEO cohorts comparing 464 newly diagnosed, R-CHOP-treated patients with FL1-2 (n = 216), FL3A (n = 170), FL3B (n = 78) and 739 DLBCL. Among FL3B patients, 19 (24%) had FL3Bc and 59 (76%) FL3Bp. Baseline characteristics and outcomes were similar between the two FL3B subtypes. Compared to FL1-3A, FL3B …

Lipid-Mediated Gating Of A Miniature Mechanosensitive Mscs Channel From Trypanosoma Cruzi, Jingying Zhang, Aashish Bhatt, Grigory Maksaev, Yun Lyna Luo, Peng Yuan

2020-Current year OA Pubs

The mechanosensitive channel of small conductance (MscS) from E. coli (EcMscS) has served as the prevailing model system for understanding mechanotransduction in ion channels. Trypanosoma cruzi, the protozoan parasite causing Chagas disease, encodes a miniature MscS ortholog (TcMscS) critical for parasite development and infectivity. TcMscS contains a minimal portion of the canonical EcMscS fold yet maintains mechanosensitive channel activity, thus presenting a unique model system to assess the essential molecular determinants underlying mechanotransduction. Using cryo-electron microscopy and molecular dynamics simulations, we show that TcMscS contains two short membrane-embedded helices that would not fully cross an intact lipid bilayer. Consequently, drastic …

Rapid development of memristive elements emulating biological neurons creates new opportunities for brain-like computation at low energy consumption. A first step toward mimicking complex neural computations is the analysis of single neurons and their characteristics. Here we measure and model spiking activity in artificial neurons built using diffusive memristors. We compare activity of these artificial neurons with the spiking activity of biological neurons measured in sensory, pre-motor, and motor cortical areas of the monkey (male) brain. We find that artificial neurons can operate in diverse self-sustained and noise-induced spiking regimes that correspond to the activity of different types of cortical …

Three Positively Charged Binding Sites On The Eastern Equine Encephalitis Virus E2 Glycoprotein Coordinate Heparan Sulfate- And Protein Receptor-Dependent Infection, Maria D H Alcorn, Chengqun Sun, Theron C Gilliland Jr, Tetyana Lukash, Christine M Crasto, Saravanan Raju, Michael S Diamond, Scott C Weaver, William B Klimstra

2020-Current year OA Pubs

Naturally circulating strains of eastern equine encephalitis virus (EEEV) bind heparan sulfate (HS) receptors and this interaction has been linked to neurovirulence. Previous studies associated EEEV-HS interactions with three positively charged amino acid clusters on the E2 glycoprotein. One of these sites has recently been reported to be critical for binding EEEV to the very-low-density lipoprotein receptor (VLDLR), an EEEV receptor protein. The proteins apolipoprotein E receptor 2 (ApoER2) isoforms 1 and 2, and LDLR have also been shown to function as EEEV receptors. Herein, we investigate the individual contribution of each HS interaction site to EEEV HS- and protein …

Ribosomes are RNA-protein complexes essential for protein synthesis and quality control. Traditional methods for ribosome isolation are labor-intensive, expensive, and require a substantial amount of biological material. In contrast, our method, RNA affinity purification using poly-lysine (RAPPL), provides a rapid, simple, and cost-effective alternative applicable to various species and types of starting material (cell lysates, whole cells, organs, or whole organisms). It is also compatible with traditional isolation techniques. Here, we describe the use of RAPPL for rapid isolation, functional screening, and structural analysis of ribosomes and associated factors. We also demonstrate the application of RAPPL in investigating ribosome-associated resistance …

Alternative To The Statistical Mass Confusion Of Testing For "No Effect", Josh L Morgan

2020-Current year OA Pubs

In cell biology, statistical analysis means testing the hypothesis that there was no effect. This weak form of hypothesis testing neglects effect size, is universally misinterpreted, and is disastrously prone to error when combined with high-throughput cell biology. The solution is for analysis of measurements to start and end with an interpretation of effect size. In this manuscript, I walk through some of the common critiques of significance testing and how they relate to experimental cell biology. I argue that careful consideration of effect size should be returned to its central position in the planning and discussion of cell biological …

UNLABELLED: Diagnostic delays in patients with brain cancer are common and can impact patient outcome. Development of a blood-based assay for detection of brain cancers could accelerate brain cancer diagnosis. In this study, we analyzed genome-wide cell-free (cfDNA) fragmentomes, including fragmentation profiles and repeat landscapes, from the plasma of individuals with (n = 148) or without (n = 357) brain cancer. Machine learning analyses of cfDNA fragmentome features detected brain cancer across all-grade gliomas (AUC = 0.90; 95% confidence interval, 0.87-0.93), and these results were validated in an independent prospectively collected cohort. cfDNA fragmentome changes in patients with gliomas represented …

An Ethanol-Induced Loss Of The Lipid Droplet-Associated Segregase Vcp/P97 Leads To Hepatic Steatosis, Sandhya Sen, Shaun Weller, Ryan J Schulze, Donglin Ding, Carol A Casey, Conrad Weihl, Mark A Mcniven

2020-Current year OA Pubs

The liver stores substantial numbers of neutral lipid organelles termed lipid droplets (LDs) that accumulate within hepatocytes in response to chronic ethanol (EtOH) consumption leading to hepatic steatosis. Mass spectrometry analysis of LDs isolated from EtOH-damaged rat livers revealed a substantial reduction in the valosin-containing protein ATPase (VCP/p97) that acts to remove targeted proteins from cellular membranes for degradation. Experimental disruption of VCP function resulted in an increase in LD content in hepatocytes and mouse livers along with a marked increase in LD-associated hydroxysteroid dehydrogenase (HSD17β13) known to contribute to hepatic steatosis. Surprisingly, treatment of hepatocytes with the proteasome inhibitor …
