Protocol To Isolate Rbp-Mrna Complexes Using Rna-Clip And Examine Target Mrnas, Valerie Blanc, Elizabeth A Molitor, Nicholas O Davidson

2020-Current year OA Pubs

RNA-binding proteins (RBPs) regulate diverse functions by interacting with target transcripts. Here we present a protocol to isolate RBP-mRNA complexes using RNA-CLIP and examine target mRNAs in association with ribosomal populations. We describe steps to identify specific RBPs and RNA targets reflecting a variety of developmental, physiological, and pathological states. This protocol enables RNP complex isolation from tissue sources (liver and small intestine) or populations of primary cells (hepatocytes), but not at a single-cell level. For complete details on the use and execution of this protocol, please refer to Blanc et al. (2014)

2020-Current year OA Pubs

PURPOSE: Quitting smoking improves patients' clinical outcomes, yet smoking is not commonly addressed as part of cancer care. The Cancer Center Cessation Initiative (C3I) supports National Cancer Institute-designated cancer centers to integrate tobacco treatment programs (TTPs) into routine cancer care. C3I centers vary in size, implementation strategies used, and treatment approaches. We examined associations of these contextual factors with treatment reach and smoking cessation effectiveness.

METHODS: This cross-sectional study used survey data from 28 C3I centers that reported tobacco treatment data during the first 6 months of 2021. Primary outcomes of interest were treatment reach (reach)-the proportion of patients identified …

Conditional Deletion Of Lrrc8a In The Brain Reduces Stroke Damage Independently Of Swelling-Activated Glutamate Release, Mustafa Balkaya, Preeti Dohare, Sophie Chen, Alexandra L Schober, Antonio M Fidaleo, Julia W Nalwalk, Rajan Sah, Alexander A Mongin

2020-Current year OA Pubs

The ubiquitous volume-regulated anion channels (VRACs) facilitate cell volume control and contribute to many other physiological processes. Treatment with non-specific VRAC blockers or brain-specific deletion of the essential VRAC subunit LRRC8A is highly protective in rodent models of stroke. Here, we tested the widely accepted idea that the harmful effects of VRACs are mediated by release of the excitatory neurotransmitter glutamate. We produced conditional LRRC8A knockout either exclusively in astrocytes or in the majority of brain cells. Genetically modified mice were subjected to an experimental stroke (middle cerebral artery occlusion). The astrocytic LRRC8A knockout yielded no protection. Conversely, the brain-wide …

2020-Current year OA Pubs

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) is a lethal malignancy. Thus, there is an urgent need for safe and effective novel therapies. PDAC's excessive reliance on glucose metabolism for its metabolic needs provides a target for metabolic therapy. Preclinical PDAC models have demonstrated that targeting the sodium-glucose co-transporter-2 (SGLT2) with dapagliflozin may be a novel strategy. Whether dapagliflozin is safe and efficacious in humans with PDAC is unclear.

METHODS: We performed a phase 1b observational study (ClinicalTrials.gov ID NCT04542291; registered 09/09/2020) to test the safety and tolerability of dapagliflozin (5 mg p.o./day × 2 weeks escalated to 10 mg p.o./day × …

2020-Current year OA Pubs

Memory problems are common among older adults with a history of alcohol use disorder (AUD). Employing a machine learning framework, the current study investigates the use of multi-domain features to classify individuals with and without alcohol-induced memory problems. A group of 94 individuals (ages 50-81 years) with alcohol-induced memory problems (the memory group) were compared with a matched control group who did not have memory problems. The random forests model identified specific features from each domain that contributed to the classification of the memory group vs. the control group (AUC = 88.29%). Specifically, individuals from the memory group manifested a …

Choroid Plexus-Targeted Nkcc1 Overexpression To Treat Post-Hemorrhagic Hydrocephalus, Cameron Sadegh, Yong Zhang, Michael J Holtzman, Et Al.

2020-Current year OA Pubs

Post-hemorrhagic hydrocephalus (PHH) refers to a life-threatening accumulation of cerebrospinal fluid (CSF) that occurs following intraventricular hemorrhage (IVH). An incomplete understanding of this variably progressive condition has hampered the development of new therapies beyond serial neurosurgical interventions. Here, we show a key role for the bidirectional Na-K-Cl cotransporter, NKCC1, in the choroid plexus (ChP) to mitigate PHH. Mimicking IVH with intraventricular blood led to increased CSF [K

The Evolution Of Primary Care Telehealth Disparities During Covid-19: Retrospective Cohort Study, Rachel D'Amico, Patrick M Schnell, Randi Foraker, J Nwando Olayiwola, Daniel E Jonas, Seuli Bose Brill

2020-Current year OA Pubs

BACKGROUND: Telehealth has become widely used as a novel way to provide outpatient care during the COVID-19 pandemic, but data about telehealth use in primary care remain limited. Studies in other specialties raise concerns that telehealth may be widening existing health care disparities, requiring further scrutiny of trends in telehealth use.

OBJECTIVE: Our study aims to further characterize sociodemographic differences in primary care via telehealth compared to in-person office visits before and during the COVID-19 pandemic and determine if these disparities changed throughout 2020.

METHODS: We conducted a retrospective cohort study in a large US academic center with 46 primary …

Distress Related To Psychotic Experiences: Enhancing The World Health Organization Composite International Diagnostic Interview Psychosis Screen, Hans Oh, Nicole R Karcher, Nirit Soffer-Dudek, Ai Koyanagi, Megan Besecker, Jordan E Devylder

2020-Current year OA Pubs

BACKGROUND: The abbreviated version of the World Health Organization (WHO) Composite International Diagnostic Interview (CIDI) psychosis screen tends to yield high prevalence in online samples. Psychotic Experiences (PE) may not necessarily indicate current or imminent psychopathology; however, distressing PE appear to be more clinically informative.

METHODS: We analyzed data collected from an online survey administered to a Qualtrics panel (N = 2522 adults). Using multivariable logistic regression, we examined the association between PE (with and without associated distress) and several mental health outcomes, adjusting for age, gender, and race/ethnicity.

RESULTS: Individuals with distressing PE had greater odds of most mental …

Circadian Clock Protein Bmal1 Broadly Influences Autophagy And Endolysosomal Function In Astrocytes, Celia A Mckee, Alexander J Polino, Melvin W King, Erik S Musiek

2020-Current year OA Pubs

An emerging role for the circadian clock in autophagy and lysosome function has opened new avenues for exploration in the field of neurodegeneration. The daily rhythms of circadian clock proteins may coordinate gene expression programs involved not only in daily rhythms but in many cellular processes. In the brain, astrocytes are critical for sensing and responding to extracellular cues to support neurons. The core clock protein BMAL1 serves as the primary positive circadian transcriptional regulator and its depletion in astrocytes not only disrupts circadian function but also leads to a unique cell-autonomous activation phenotype. We report here that astrocyte-specific deletion …

2020-Current year OA Pubs

Breast density, the amount of fibroglandular versus fatty tissue in the breast, is a strong breast cancer risk factor. Understanding genetic factors associated with breast density may help in clarifying mechanisms by which breast density increases cancer risk. To date, 50 genetic loci have been associated with breast density, however, these studies were performed among predominantly European ancestry populations. We utilized a cohort of women aged 40-85 years who underwent screening mammography and had genetic information available from the Penn Medicine BioBank to conduct a Genome-Wide Association Study (GWAS) of breast density among 1323 women of African ancestry. For each …

How Does Facilitation In Healthcare Work? Using Mechanism Mapping To Illuminate The Black Box Of A Meta-Implementation Strategy, Amy M Kilbourne, Elvin Geng, Ingrid Eshun-Wilson, Shannon Sweeney, Donna Shelley, Deborah J Cohen, Joann E Kirchner, Maria E Fernandez, Michael L Parchman

2020-Current year OA Pubs

BACKGROUND: Healthcare facilitation, an implementation strategy designed to improve the uptake of effective clinical innovations in routine practice, has produced promising yet mixed results in randomized implementation trials and has not been fully researched across different contexts.

OBJECTIVE: Using mechanism mapping, which applies directed acyclic graphs that decompose an effect of interest into hypothesized causal steps and mechanisms, we propose a more concrete description of how healthcare facilitation works to inform its further study as a meta-implementation strategy.

METHODS: Using a modified Delphi consensus process, co-authors developed the mechanistic map based on a three-step process. First, they developed an initial …

A Single-Cell Multiomic Analysis Of Kidney Organoid Differentiation, Yasuhiro Yoshimura, Yoshiharu Muto, Nicolas Ledru, Haojia Wu, Kohei Omachi, Jeffrey H Miner, Benjamin D Humphreys

2020-Current year OA Pubs

Kidney organoids differentiated from pluripotent stem cells are powerful models of kidney development and disease but are characterized by cell immaturity and off-target cell fates. Comparing the cell-specific gene regulatory landscape during organoid differentiation with human adult kidney can serve to benchmark progress in differentiation at the epigenome and transcriptome level for individual organoid cell types. Using single-cell multiome and histone modification analysis, we report more broadly open chromatin in organoid cell types compared to the human adult kidney. We infer enhancer dynamics by cis-coaccessibility analysis and validate an enhancer driving transcription of

2020-Current year OA Pubs

Insulin-producing β cells created from human pluripotent stem cells have potential as a therapy for insulin-dependent diabetes, but human pluripotent stem cell-derived islets (SC-islets) still differ from their in vivo counterparts. To better understand the state of cell types within SC-islets and identify lineage specification deficiencies, we used single-nucleus multi-omic sequencing to analyse chromatin accessibility and transcriptional profiles of SC-islets and primary human islets. Here we provide an analysis that enabled the derivation of gene lists and activity for identifying each SC-islet cell type compared with primary islets. Within SC-islets, we found that the difference between β cells and awry …

Biomechanical Models And Mechanisms Of Cellular Morphogenesis And Cerebral Cortical Expansion And Folding, David C Van Essen

2020-Current year OA Pubs

Morphogenesis of the nervous system involves a highly complex spatio-temporal pattern of physical forces (mainly tension and pressure) acting on cells and tissues that are pliable but have an intricately organized cytoskeletal infrastructure. This review begins by covering basic principles of biomechanics and the core cytoskeletal toolkit used to regulate the shapes of cells and tissues during embryogenesis and neural development. It illustrates how the principle of 'tensegrity' provides a useful conceptual framework for understanding how cells dynamically respond to forces that are generated internally or applied externally. The latter part of the review builds on this foundation in considering …

Strategies To Bridge Equitable Implementation Of Telehealth, Allison M Gustavson, Allison A Lewinski, Ellen E Fitzsimmons-Craft, Gloria D Coronado, Sarah E Linke, Denalee M O'Malley, Alyce S Adams, Russell E Glasgow, Lisa M Klesges

2020-Current year OA Pubs

During the COVID-19 pandemic, the rapid scaling of telehealth limited the extent to which proactive planning for equitable implementation was possible. The deployment of telehealth will persist in the postpandemic era, given patient preferences, advances in technologies, growing acceptance of telehealth, and the potential to overcome barriers to serve populations with limited access to high-quality in-person care. However, aspects and unintended consequences of telehealth may leave some groups underserved or unserved, and corrective implementation plans that address equitable access will be needed. The purposes of this paper are to (1) describe equitable implementation in telehealth and (2) integrate an equity …

2020-Current year OA Pubs

Molecules involved in drug resistance can be targeted for better therapeutic efficacies. Research on midkine (MDK) has escalated in the last few decades, which affirms a positive correlation between disease progression and MDK expression in most cancers and indicates its association with multi-drug resistance in cancer. MDK, a secretory cytokine found in blood, can be exploited as a potent biomarker for the non-invasive detection of drug resistance expressed in various cancers and, thereby, can be targeted. We summarize the current information on the involvement of MDK in drug resistance, and transcriptional regulators of its expression and highlight its potential as …

Triggering receptor expressed on myeloid cells 2 (TREM2) plays important roles in brain microglial function in neurodegenerative diseases, but the role of TREM2 in the GBM TME has not been examined. Here, we found that TREM2 is highly expressed in myeloid subsets, including macrophages and microglia in human and mouse GBM tumors and that high TREM2 expression correlates with poor prognosis in patients with GBM. TREM2 loss of function in human macrophages and mouse myeloid cells increased interferon-γ-induced immunoactivation, proinflammatory polarization, and tumoricidal capacity. In orthotopic mouse GBM models, mice with chronic and acute Trem2 loss of function exhibited decreased …

Data Envelopment Analysis To Evaluate The Efficiency Of Tobacco Treatment Programs In The Nci Moonshot Cancer Center Cessation Initiative, Kathryn Pluta, Li-Shiun Chen, Et Al.

2020-Current year OA Pubs

BACKGROUND: The Cancer Center Cessation Initiative (C3I) is a National Cancer Institute (NCI) Cancer Moonshot Program that supports NCI-designated cancer centers developing tobacco treatment programs for oncology patients who smoke. C3I-funded centers implement evidence-based programs that offer various smoking cessation treatment components (e.g., counseling, Quitline referrals, access to medications). While evaluation of implementation outcomes in C3I is guided by evaluation of reach and effectiveness (via RE-AIM), little is known about technical efficiency-i.e., how inputs (e.g., program costs, staff time) influence implementation outcomes (e.g., reach, effectiveness). This study demonstrates the application of data envelopment analysis (DEA) as an implementation science tool …
