Pip2-Driven Cytoplasmic Domain Motions Are Coupled To Kir2 Channel Gating, Eva-Maria Zangerl-Plessl, Anna Stary-Weinzinger, Colin G Nichols, Sun-Joo Lee

2020-Current year OA Pubs

Inwardly rectifying potassium (Kir) channel activity is important in the control of membrane potentials in both excitable and non-excitable cells and is regulated through various ligands, including specific membrane lipids. Phosphatidyl-4,5-bisphosphate (PIP2) is required for activity of all Kir channels, binding to the cytoplasmic domain in a compact conformation tightly tethered to the transmembrane domain. Most Kir2 channel structures determined in complex with PIP2 molecules are nevertheless in a closed state, requiring additional conformational changes for channel opening. We have carried out full atomistic MD simulations, which indicate PIP2-dependent conformational changes that are coupled to opening and closing of the …

Muscle Fatigue Arising Intrinsically From Sur2- But Not Kir6.1-Dependent Gain-Of-Function In Cantu Syndrome Mice, Rosa Scala, Maya Mukadam, Yuezhou Chen, Courtney Frazier, Nathaniel W York, Robert C Tryon, Gretchen A Meyer, Colin G Nichols

2020-Current year OA Pubs

Cantu syndrome (CS) is a rare disease caused by gain-of-function (GOF) mutations of Kir6.1 or SUR2 subunits of ATP-sensitive potassium (KATP) channels. CS patients with SUR2 and Kir6.1 variants display a similar constellation of symptoms, including muscle weakness and fatigue. The effects of CS mutations on skeletal muscle KATP channels, and any consequent direct effects on contractility, are currently unclear. Here, we used two knock-in mouse models of CS, respectively, carrying GOF mutations Kir6.1[V65M] or SUR2[A478V], to assess KATP channel properties and contractility in isolated fast-twitch extensor digitorum longus (EDL) and slow-twitch soleus (SOL) muscles. Electrophysiological recordings in isolated myofibers …

A Clinical Practice Guideline For The Management Of Pregnancy Alloimmunized To Red Blood Cell Antigens, Kenneth J Moise, Jay Malone, Et Al.

2020-Current year OA Pubs

IMPORTANCE: Red blood cell alloimmunization is typically associated with the transplacental transfer of incompatible fetal red blood cells into maternal circulation. Subsequent pregnancies can be affected by fetal anemia, hydrops fetalis, and perinatal death. Most cases of Rhesus D (RhD) alloimmunization due to pregnancy can be prevented by the proper administration of Rhesus immune globulin. However, an emerging practice of using low-titer, O, RhD-positive whole blood (LTOWB) in cases of life-threatening hemorrhage has the potential to increase the exposure of the female population to a new source of incompatible red blood cells.

OBJECTIVE: To establish recommendations for the management of …

Overexpression Of The Signaling Coordinator Gab2 Can Play An Important Role In Acute Myeloid Leukemia Progression, Michael H. Kramer, Stephanie N. Richardson, Yang Li, Tiankai Yin, Nichole M.

Mutations that initiate acute myeloid leukemia (AML) can cause clonal expansion without transformation (clonal hematopoiesis). Cooperating mutations, usually in signaling genes, are needed to cause overt disease, but these may require a specific fitness state to be tolerated. Here, we show that nearly all AMLs arising in a mouse model expressing 2 common AML-initiating mutations (Dnmt3aR878H and Npm1cA) acquired a single copy amplification of chromosome 7 (chr7), followed by activating mutations in signaling genes. We show that overexpression of a single gene on chr7 (Gab2, which coordinates signaling pathways) was tolerated in the presence of the Npm1cA mutation, could accelerate …

Availability Of Multidisciplinary Treatment Modalities And Outcomes Among Patients With Resected Early-Stage Non-Small Cell Lung Cancer, Brendan T Heiden, Su-Hsin Chang, Yan Yan, Ana A Baumann, Theodore S Thomas, Steven Tohmasi, Nikki Rossetti, Daniel Kreisel, Ruben G Nava, Bryan F Meyers, Benjamin D Kozower, Varun Puri, Et Al.

2020-Current year OA Pubs

BACKGROUND: Comprehensive, multidisciplinary care is crucial for managing early-stage non-small cell lung cancer (NSCLC), typically treated via lung resection or stereotactic body radiation therapy (SBRT).

Hospitals were categorized based on their annual volume of lung cancer resections. Multivariable regression models …

Hiv Pre-Exposure Prophylaxis Does Not Increase Gonorrhea And Chlamydia Incidence In Young Black And Hispanic Men Who Have Sex With Men: An Observational Cohort Study, Octavio C Mesner, Rishabh Jain, Aditi Ramakrishnan, Derrick D Matthews, Jeremy T Goldbach

2020-Current year OA Pubs

BACKGROUND: HIV pre-exposure prophylaxis (PrEP) use has been linked with increases in sexually transmitted infection (STI) incidence. Despite efforts to expand PrEP uptake among young Black and Hispanic men who have sex with men (YBHMSM), little research has been done to understand the impact of PrEP on STI incidence within these communities. We examine the effect of PrEP use on gonorrhea and chlamydia (NG/CT) incidence, condom use, and external STI testing (ie, outside of study visits).

METHODS: In a longitudinal cohort of HIV-negative YBHMSM (ages 16-24 years), we modeled the effect of PrEP use on study-external STI testing and number …

Context-Dependent Contribution Of Peptidyl Arginine Deiminase 4 (Pad4) To Neutrophil Extracellular Trap Formation And Liver Injury In Acute And Chronic Hepatotoxicant Challenge, Gina E Capece, Amish K Patel, Daniel Hu, Tayana Roychowdhury, Bianca Hazel, Jessica Kothapalli, Noah A Mac, Frederik Denorme, Robert A Campbell, Lauren G Poole

2020-Current year OA Pubs

Neutrophils play a complex role in the pathogenesis of chronic liver disease and have been linked to both liver damage and injury resolution. Recent reports propose that neutrophils drive liver injury and fibrosis through the formation of neutrophil extracellular traps (NETs). This study tests the hypothesis that the enzyme peptidyl arginine deiminase-4 (PAD4) drives NET formation and liver fibrosis in experimental chronic liver injury. Wild-type (PAD4+/+) and PAD4-deficient (PAD4-/-) mice were chronically challenged twice weekly with carbon tetrachloride (CCl4, 1 ml/kg, i.p) or vehicle (corn oil) for 6 weeks, and samples were collected 24 h after the final challenge.

While circadian rhythm disruption may promote neurodegenerative disease, the impact of aging and neurodegenerative pathology on circadian gene expression patterns in different brain cell types remains unknown. Here we used a translating ribosome affinity purification to identify the circadian translatomes of astrocytes, microglia and bulk tissue in healthy mouse cortex and in the settings of amyloid-β plaque pathology or aging. We show that glial circadian translatomes are highly cell-type-specific and exhibit profound, context-dependent reprogramming in response to amyloid pathology or aging. Transcripts involved in glial reactivity, immunometabolism and proteostasis, as well as nearly half of all Alzheimer's disease risk genes, …

Identifying Performance Differences Between Two Pulse Oximetry Systems In Simulated Critical Neonatal Conditions, Brian King, Jake Dove, Scott J Mcgonigle, Warwick A Ames, Zachary A Vesoulis

2020-Current year OA Pubs

OBJECTIVE: Pulse oximetry is used to guide critical clinical decisions in neonatology. We used a vital signs simulator to compare performance of two pulse oximetry systems in conditions not tested in standardized clinical verification studies.

STUDY DESIGN: We devised a set of simulated tissue translucency, perfusion, peripheral oxygen saturation (SpO

RESULTS: The mean SpO

CONCLUSION: Significant performance differences can be observed when comparing pulse oximeters at low translucency and perfusion conditions. Patient simulators cannot replace clinical testing but provide a safe and cost-effective method for additional performance profiling.

Degenerating Intervertebral Discs In The Streptozotocin-High-Fat Diet Model Of Type 2 Diabetes Show Extensive Inflammation, Christian E Gonzalez, Rachana S Vaidya, Sade W Clayton, Simon Y Tang

2020-Current year OA Pubs

The chronic inflammation observed during type 2 diabetes (T2D) is associated with spinal pathologies, including intervertebral disc (IVD) degeneration and chronic spine pain. Despite confounding factors, such as obesity, studies show that, after adjusting for age, body mass index and genetics (e.g. twins), patients with T2D experience disproportionate severity of IVD degeneration and/or back pain than individuals without T2D. We hypothesized that chronic T2D fosters a proinflammatory microenvironment within the IVD that promotes degeneration and disrupts homeostasis. To test this, we evaluated two common mouse models of T2D - leptin-receptor deficient (db/db) mice and mice with a chronic high-fat diet …

Six Drivers Of Aging Identified Among Genes Differentially Expressed With Age, Ariella Coler-Reilly, Zachary Pincus, Erica L Scheller, Roberto Civitelli

2020-Current year OA Pubs

Many studies have compared gene expression in young and old samples to gain insights on aging, the primary risk factor for most chronic diseases. However, these studies only identify associations without distinguishing drivers of aging from compensatory geroprotective responses or incidental downstream effects. Here, we introduce a workflow to characterize causal effects of differentially expressed genes on lifespan. First, we performed a meta-analysis of 25 gene expression datasets comprising samples of various tissues from healthy, untreated adult mammals (humans, dogs, and rodents) at two distinct ages. Genes were ranked by the number of datasets in which they exhibited consistent differential …

Maternal Separation Disrupts Noradrenergic Control Of Adult Coping Behaviors, Chayla R Vazquez, Léa J Becker, Chao-Cheng Kuo, Solana A Cariello, Ayah N Hamdan, Ream Al-Hasani, Susan E Maloney, Jordan G Mccall

2020-Current year OA Pubs

Early life stress (ELS) profoundly impacts the brain and correlates with negative affective behaviors in adulthood. The locus coeruleus (LC), a stress-responsive brainstem nucleus that supplies most of the brain with norepinephrine (NE), is known to modulate negative affect. Using repeated maternal separation stress (MSS), we investigated the impact of ELS on the LC and stress-related behaviors in adulthood. We performed ex vivo cell-attached electrophysiology across the lifespan to reveal that MSS significantly increased LC firing during early development and adulthood but not in pre-adolescence and adolescence. We next examined potential changes in the expression of genes linked to LC …

Autophagy is an essential cellular process which functions to maintain homeostasis in response to stressors such as starvation or infection. Here, we report that a subset of autophagy factors including ATG-3 play an antiviral role in Orsay virus infection of Caenorhabditis elegans. Orsay virus infection does not modulate autophagic flux, and re-feeding after starvation limits Orsay virus infection and blocks autophagic flux, suggesting that the role of ATG-3 in Orsay virus susceptibility is independent of its role in maintaining autophagic flux. atg-3 mutants phenocopy rde-1 mutants, which have a defect in RNA interference (RNAi), in susceptibility to Orsay virus infection …

Episodic Memory Involves Transient And Sparse Connectivity Aligned To Both Internal And External Events, Adam J. O. Dede, Peter Brunner, Jarod L. Roland, Et Al.

2020-Current year OA Pubs

Episodic memory depends on the coordination of local processing, indexed by high-frequency broadband (HFB) activity, with global organization, indexed by theta oscillations. However, theta and HFB exhibit asynchronous timing, raising the question of how results of local processing are communicated. Using intracranial EEG in patients performing a recognition memory task, we examined this coordination across medial temporal (MTL) and prefrontal (PFC) regions. HFB peaks occurred earlier in the MTL than in the PFC. Contrasting analyses were anchored either to these internally driven HFB peaks or to the external event of stimulus presentation. We discovered three key results. First, the role …
