Elevated truncated oxidized phospholipids as a factor exacerbating ALI in the aging lungs.

FASEB J 2018 Dec 6:fj201800981R. Epub 2018 Dec 6.

Department of Anesthesiology, University of Maryland School of Medicine, Baltimore, Maryland, USA.

As mechanisms controlling redox homeostasis become impaired with aging, exaggerated oxidant stress may cause disproportional oxidation of cell membranes and circulating phospholipids (PLs), leading to the formation of truncated oxidized PL products (Tr-OxPLs), which exhibit deleterious effects. This study investigated the role of elevated Tr-OxPLs as a factor exacerbating inflammation and lung barrier dysfunction in an animal model of aging. Mass spectrometry analysis of Tr-OxPL species in young (2-4 mo) and aging (18-24 mo) mice revealed elevated basal levels of several products [1-palmitoyl-2-(5-oxovaleroyl)- sn-glycero-phosphocholine (POVPC), 1-palmitoyl-2-glutaroyl- sn-glycero-phosphocholine, lysophosphocholine, 1-palmitoyl-2-(9-oxo-nonanoyl)- sn-glycero-3-phosphocholine, 1-palmitoyl-2-azelaoyl- sn-glycero-3-phosphocholine, O-1-O-palmitoyl-2-O-(5,8-dioxo-8-hydroxy-6-octenoyl)-l-glycero-3-phosphocholine, and others] in the aged lungs.

Possible cold-adaptation for the fungal kinesin in compensation for thermal stability acquired by single amino acid substitution.

J Biochem 2018 Dec 5. Epub 2018 Dec 5.

Department of Biosciences, College of Humanities and Sciences, Nihon University, 3-25-40 Sakurajosui, Setagaya-ku, Tokyo, Japan.

The amino acid sequence of the motor domain of AnKinA, kinesin-1 from Aspergillus nidulans, growing optimally at 37°C, was compared with that of SbKin1, kinesin-1 from the snow mold Sclerotinia borealis. For cold-adaptation, some enzymes are thought to exhibit augmented protein structure flexibility, acquired most effectively by substituting a glycine residue for another amino acid residue. By the comparison described above, two glycine residues proximal to tightly-bound ADP were identified in the SbKin1 motor domain, of which the corresponding residues of AnKinA were non-glycine ones (P60 and S323).

Department of Pathology and Laboratory Medicine, Indiana University School of Medicine, Indianapolis, IN, USA.

Autophagy is important for hepatic homeostasis, nutrient regeneration and organelle quality control. We investigated the mechanisms by which liver injury occurred in the absence of autophagy function. We found that mice deficient in autophagy due to the lack of Atg7 or Atg5, key autophagy-related genes, manifested intracellular cholestasis with increased levels of serum bile acids, a higher ratio of TMCA/TCA in the bile, increased hepatic bile acid load, abnormal bile canaliculi and altered expression of hepatic transporters.

Nervous system characterization during the development of a basal echinoderm, the feather star Antedon mediterranea.

J Comp Neurol 2018 Dec 6. Epub 2018 Dec 6.

Department of Environmental Science and Policy, Università degli Studi di Milano, Milano, Italy.

Neural development of echinoderms has always been difficult to interpret, as larval neurons degenerate at metamorphosis and a tripartite nervous system differentiates in the adult. Despite their key phylogenetic position as basal echinoderms, crinoids have been scarcely studied in developmental research. However, since they are the only extant echinoderms retaining the ancestral body plan of the group, crinoids are extremely valuable models to clarify neural evolution in deuterostomes. Read More

Computational Analyses Connect Small-Molecule Sensitivity to Cellular Features Using Large Panels of Cancer Cell Lines.

Methods Mol Biol 2019 ;1888:233-254

Chemical Biology and Therapeutics Science Program, Broad Institute of Harvard and MIT, Cambridge, MA, USA.

We recently pioneered several analyses of small-molecule sensitivity data collected from large-scale perturbation of hundreds of cancer cell lines with hundreds of small molecules, with cell viability measured as a readout of compound sensitivity. We performed these studies using cancer cell lines previously annotated with cellular, genomic, and basal gene-expression features. By combining small-molecule sensitivity data with these other datasets, we identified new candidate biomarkers of sensitivity, gained insights into small-molecule mechanisms of action, and proposed candidate hypotheses for cancer dependencies (including candidate combination therapies).

Conditional Haploinsufficiency of β-Catenin Aggravates Neuronal Damage in a Paraquat-Based Mouse Model of Parkinson Disease.

Mol Neurobiol 2018 Dec 6. Epub 2018 Dec 6.

Department of Pathology, Case Western Reserve University, 2103 Cornell Road, Cleveland, OH, 44106, USA.

The canonical Wnt pathway is critical for both the development and adulthood survival and homeostatic maintenance of the midbrain dopaminergic (DA) neurons. Expanding evidence has demonstrated that genetic factors associated with familial Parkinson disease (PD) deregulate this important pathway, suggesting that a disturbed canonical Wnt pathway is likely involved in PD pathogenesis; yet, the specific role of this pathway in sporadic PD remains unclear. In this study, we aimed to determine the effects of specific inhibition of the canonical pathway by hemizygous knockout of β-catenin, the obligatory component of the canonical Wnt pathway, on paraquat (PQ)-induced DA neuronal degeneration in the substantia nigra in vivo.

Eukaryotic Voltage-Gated Sodium Channels: On Their Origins, Asymmetries, Losses, Diversification and Adaptations.

Front Physiol 2018 21;9:1406. Epub 2018 Nov 21.

Department of Biology, University of Waterloo, Waterloo, ON, Canada.

The appearance of voltage-gated, sodium-selective channels with rapid gating kinetics was a limiting factor in the evolution of nervous systems. Two rounds of domain duplications generated a common 24 transmembrane segment (4 × 6 TM) template that is shared amongst voltage-gated sodium (Na1 and Na2) and calcium channels (Ca1, Ca2, and Ca3) and leak channel (NALCN) plus homologs from yeast, different single-cell protists (heterokont and unikont) and algae (green and brown). A shared architecture in 4 × 6 TM channels include an asymmetrical arrangement of extended extracellular L5/L6 turrets containing a 4-0-2-2 pattern of cysteines, glycosylated residues, a universally short III-IV cytoplasmic linker and often a recognizable, C-terminal PDZ binding motif.

Visualization of Exo- and Endocytosis of AMPA Receptors During Hippocampal Synaptic Plasticity Around Postsynaptic-Like Membrane Formed on Glass Surface.

Authors:
Tomoo Hirano

Front Cell Neurosci 2018 21;12:442. Epub 2018 Nov 21.

Department of Biophysics, Graduate School of Science, Kyoto University, Kyoto, Japan.

Regulation of exo- and endocytosis of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-type glutamate receptor (AMPAR) plays a critical role in the expression of synaptic plasticity such as long-term potentiation (LTP) and long-term depression (LTD) at excitatory central synapses. Enhanced AMPAR exocytosis or endocytosis has been suggested to contribute to LTP or LTD, respectively. However, several unsettled fundamental questions have remained about AMPAR exo- and endocytosis in the basal condition and during synaptic plasticity: (1) Does the size of each exo- or endocytosis event, and/or do the frequencies of these events change during LTP or LTD? If they change, what are the time courses of the respective changes? (2) Where does the exo- or endocytosis preferentially occur in each condition: inside or in the vicinity of postsynaptic membrane, or in the extrasynaptic membrane? (3) Do different types of AMPAR, such as GluA1 homo-tetramer, GluA1/2 hetero-tetramer and GluA2/3 hetero-tetramer, show distinct exo- and endocytosis changes? To address these questions, we developed new methods to observe individual events of AMPAR exo- or endocytosis with a high signal to noise (SN) ratio in a culture preparation using total internal reflection fluorescence microscopy (TIRFM).

Keck School of Medicine of University of Southern California, Division of Neonatology, Department of Pediatrics, LAC+USC Medical Center, Los Angeles, CA, USA.

Neonatal hyperbilirubinemia is one of the most frequent diagnoses made in neonates. A high level of unconjugated bilirubin that is unbound to albumin is neurotoxic when the level exceeds age-specific thresholds or at lower levels in neonates with neurotoxic risk factors. Lower range of unbound bilirubin results in apoptosis, while moderate-to-high levels result in neuronal necrosis. Read More

Mechanistic framework for cell-intrinsic re-establishment of PIN2 polarity after cell division.

Nat Plants 2018 Dec 3;4(12):1082-1088. Epub 2018 Dec 3.

IST Austria, Klosterneuburg, Austria.

Cell polarity, manifested by the localization of proteins to distinct polar plasma membrane domains, is a key prerequisite of multicellular life. In plants, PIN auxin transporters are prominent polarity markers crucial for a plethora of developmental processes. Cell polarity mechanisms in plants are distinct from other eukaryotes and still largely elusive. Read More

Cryopreservation of primary B cells minimally influences their signaling responses.

Sci Rep 2018 Dec 5;8(1):17651. Epub 2018 Dec 5.

Centre for Molecular Medicine Norway, Nordic EMBL Partnership, University of Oslo and Oslo University Hospital, Oslo, Norway.

Phospho flow is a powerful approach to detect cell signaling aberrations, identify biomarkers and assess pharmacodynamics, and can be performed using cryopreserved samples. The effects of cryopreservation on signaling responses and the reproducibility of phospho flow measurements are however unknown in many cell systems. Here, B lymphocytes were isolated from healthy donors and patients with the B cell malignancy chronic lymphocytic leukemia and analyzed by phospho flow using phospho-specific antibodies targeting 20 different protein epitopes.

Involvement of transient receptor potential melastatin 4 channels in the resting membrane potential setting and cholinergic contractile responses in mouse detrusor and ileal smooth muscles.

J Vet Med Sci 2018 Dec 6. Epub 2018 Dec 6.

Department of Pathogenetic Veterinary Science, United Graduate School of Veterinary Science, Gifu University.

Here, we investigated the effects of 9-hydroxyphenanthrene (9-phenanthrol), a potent and selective transient receptor potential melastatin 4 (TRPM4) channel blocker, on the resting membrane potential and cholinergic contractile responses to elucidate the functional role of TRPM4 channels in the contractile activities of mouse detrusor and ileal longitudinal smooth muscles. We observed that, 9-phenanthrol (3-30 µM) did not significantly inhibit high K-induced contractions in both preparations; however, 9-phenanthrol (10 µM) strongly inhibited cholinergic contractions evoked by electrical field stimulation in detrusor preparations compared to inhibitions in ileal preparations. 9-Phenanthrol (10 µM) significantly inhibited the muscarinic agonist, carbachol-induced contractile responses and slowed the maximum upstroke velocities of the contraction in detrusor preparations.

Bexarotene - a novel modulator of AURKA and the primary cilium in -deficient cells.

J Cell Sci 2018 Dec 5. Epub 2018 Dec 5.

Center for Precision Environmental Health, Baylor College of Medicine, Houston, TX, USA

Loss of () is associated with loss of primary cilia and is causally linked to elevated Aurora Kinase A (AURKA). We developed an image-based HTS assay using a dual-labelling image analysis strategy that identifies both the cilium and the basal body. Using this strategy, we screened small molecule compounds for the targeted rescue of cilia defects associated with -deficiency with high accuracy and reproducibility. Read More

Alzheimer's Disease Risk Factor Pyk2 Mediates Amyloid-β Induced Synaptic Dysfunction and Loss.

J Neurosci 2018 Dec 5. Epub 2018 Dec 5.

Cellular Neuroscience, Neurodegeneration & Repair, Departments of Neurology and of Neuroscience, Yale University School of Medicine, New Haven, CT USA 06536.

Dozens of genes have been implicated in Late Onset Alzheimer's Disease (AD) risk, but none have a defined mechanism of action in neurons. Here, we show that the risk factor Pyk2 (PTK2B) localizes specifically to neurons in adult brain. Absence of Pyk2 has no major effect on synapse formation nor the basal parameters of synaptic transmission in the hippocampal Schaffer collateral pathway. Read More

Probing the interface structure of adhering cells by contrast variation neutron reflectometry.

Langmuir 2018 Dec 5. Epub 2018 Dec 5.

Cellular adhesion is a central element in tissue mechanics, biological cell-cell signaling, and cell motility. In this context, the cell-substrate distance has been investigated in the past by studying natural cells and biomimetic cell models adhering on solid substrates. The amount of water in the membrane substrate gap, however, is difficult to determine. Read More
