--- _id: '1981' abstract: - lang: eng text: Variation in mitochondrial DNA is often assumed to be neutral and is used to construct the genealogical relationships among populations and species. However, if extant variation is the result of episodes of positive selection, these genealogies may be incorrect, although this information itself may provide biologically and evolutionary meaningful information. In fact, positive Darwinian selection has been detected in the mitochondrial-encoded subunits that comprise complex I from diverse taxa with seemingly dissimilar bioenergetic life histories, but the functional implications of the selected sites are unknown. Complex I produces roughly 40% of the proton flux that is used to synthesize ATP from ADP, and a functional model based on the high-resolution structure of complex I described a unique biomechanical apparatus for proton translocation. We reported positive selection at sites in this apparatus during the evolution of Pacific salmon, and it appeared this was also the case in published reports from other taxa, but a comparison among studies was difficult because different statistical tests were used to detect selection and oftentimes, specific sites were not reported. Here we review the literature of positive selection in mitochondrial genomes, the statistical tests used to detect selection, and the structural and functional models that are currently available to study the physiological implications of selection. We then search for signatures of positive selection among the coding mitochondrial genomes of 237 species with a common set of tests and verify that the ND5 subunit of complex I is a repeated target of positive Darwinian selection in diverse taxa. We propose a novel hypothesis to explain the results based on their bioenergetic life histories and provide a guide for laboratory and field studies to test this hypothesis. acknowledgement: Funded by University of Alaska Center for Global Change Student Research Cooperative Institute for Alaska Research and the Rasmuson Foundation author: - first_name: Michael full_name: Garvin, Michael R last_name: Garvin - first_name: Joseph full_name: Bielawski, Joseph P last_name: Bielawski - first_name: Leonid A full_name: Leonid Sazanov id: 338D39FE-F248-11E8-B48F-1D18A9856A87 last_name: Sazanov orcid: 0000-0002-0977-7989 - first_name: Anthony full_name: Gharrett, Anthony J last_name: Gharrett citation: ama: Garvin M, Bielawski J, Sazanov LA, Gharrett A.

The lack of NDH-2 in mammalian mitochondria and its essentiality in important bacterial pathogens suggests these enzymes may represent a potential new drug target to combat microbial pathogens. Here, we report the first crystal structure of a bacterial NDH-2 enzyme at 2.5Å resolution from Caldalkalibacillus thermarum. The NDH-2 structure reveals a homodimeric organization that has a unique dimer interface. NDH-2 is localized to the cytoplasmic membrane by two separated C-terminal membrane-anchoring regions that are essential for membrane localization and FAD binding, but not NDH-2 dimerization. Comparison of bacterial NDH-2 with the yeast NADH dehydrogenase (Ndi1) structure revealed non-overlapping binding sites for quinone and NADH in the bacterial enzyme. The bacterial NDH-2 structure establishes a framework for the structure-based design of small-molecule inhibitors. acknowledgement: Funded by Health Research Council of New Zealand Royal Society of New Zealand University of Otago New Zealand Synchrotron Group author: - first_name: Adam full_name: 'Heikal, Adam ' last_name: Heikal - first_name: Yoshio full_name: Nakatani, Yoshio last_name: Nakatani - first_name: Elyse full_name: Dunn, Elyse A last_name: Dunn - first_name: Marion full_name: Weimar, Marion R last_name: Weimar - first_name: Catherine full_name: Day, Catherine last_name: Day - first_name: Edward full_name: Baker, Edward N last_name: Baker - first_name: Shaun full_name: Lott, Shaun J last_name: Lott - first_name: Leonid A full_name: Leonid Sazanov id: 338D39FE-F248-11E8-B48F-1D18A9856A87 last_name: Sazanov orcid: 0000-0002-0977-7989 - first_name: Gregory full_name: Cook, Gregory last_name: Cook citation: ama: 'Heikal A, Nakatani Y, Dunn E, et al.

It couples the transfer of two electrons between NADH and ubiquinone to the translocation of four protons across the membrane. Complex I is an L-shaped assembly formed by the hydrophilic (peripheral) arm, containing all the redox centres performing electron transfer and the membrane arm, containing proton-translocating machinery. Mitochondrial complex I consists of 44 subunits of about 1 MDa in total, whilst the prokaryotic enzyme is simpler and generally consists of 14 conserved “core” subunits. Recently we have determined the first atomic structure of the entire complex I, using the enzyme from Thermus thermophilus (536 kDa, 16 subunits, 9 Fe-S clusters, 64 TM helices). Structure suggests a unique coupling mechanism, with redox energy of electron transfer driving proton translocation via long-range (up to ~200 Å) conformational changes. It resembles a steam engine, with coupling elements (akin to coupling rods) linking parts of this molecular machine. author: - first_name: Leonid A full_name: Leonid Sazanov id: 338D39FE-F248-11E8-B48F-1D18A9856A87 last_name: Sazanov orcid: 0000-0002-0977-7989 citation: ama: Sazanov LA.

We developed a cell-free system to recapitulate cytokinesis signaling using cytoplasmic extract from Xenopus eggs. Microtubules grew out as asters from artificial centrosomes and met to organize antiparallel overlap zones. These zones blocked the interpenetration of neighboring asters and recruited cytokinesis midzone proteins, including the chromosomal passenger complex (CPC) and centralspindlin. The CPC was transported to overlap zones, which required two motor proteins, Kif4A and a Kif20A paralog. Using supported lipid bilayers to mimic the plasma membrane, we observed the recruitment of cleavage furrow markers, including an active RhoA reporter, at microtubule overlaps. This system opens further approaches to understanding the biophysics of cytokinesis signaling. acknowledgement: 'This work was supported by NIH grant GM39565 (T.J.M.); MBL fellowships from the Evans Foundation, MBL Associates, and the Colwin Fund (T.J.M. and C.M.F.); HFSP fellowship LT000466/2012-L (M.L.); and NIH grant GM103785 (M.W.).

Auxin distribution is regulated by auxin-dependent positive feedback loops that are not well-understood at the molecular level. Previously, we showed the involvement of the RHO of Plants (ROP) effector INTERACTOR of CONSTITUTIVELY active ROP 1 (ICR1) in regulation of auxin transport and that ICR1 levels are posttranscriptionally repressed at the site of maximum auxin accumulation at the root tip. Here, we show that bimodal regulation of ICR1 levels by auxin is essential for regulating formation of auxin local maxima and gradients. ICR1 levels increase concomitant with increase in auxin response in lateral root primordia, cotyledon tips, and provascular tissues. However, in the embryo hypophysis and root meristem, when auxin exceeds critical levels, ICR1 is rapidly destabilized by an SCF(TIR1/AFB) [SKP, Cullin, F-box (transport inhibitor response 1/auxin signaling F-box protein)]-dependent auxin signaling mechanism. Furthermore, ectopic expression of ICR1 in the embryo hypophysis resulted in reduction of auxin accumulation and concomitant root growth arrest. ICR1 disappeared during root regeneration and lateral root initiation concomitantly with the formation of a local auxin maximum in response to external auxin treatments and transiently after gravitropic stimulation. Destabilization of ICR1 was impaired after inhibition of auxin transport and signaling, proteasome function, and protein synthesis. A mathematical model based on these findings shows that an in vivo-like auxin distribution, rootward auxin flux, and shootward reflux can be simulated without assuming preexisting tissue polarity. Our experimental results and mathematical modeling indicate that regulation of auxin distribution is tightly associated with auxin-dependent ICR1 levels. author: - first_name: Ora full_name: Hazak, Ora last_name: Hazak - first_name: Uri full_name: Obolski, Uri last_name: Obolski - first_name: Tomas full_name: Prat, Tomas id: 3DA3BFEE-F248-11E8-B48F-1D18A9856A87 last_name: Prat - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Lilach full_name: Hadany, Lilach last_name: Hadany - first_name: Shaul full_name: Yalovsky, Shaul last_name: Yalovsky citation: ama: Hazak O, Obolski U, Prat T, Friml J, Hadany L, Yalovsky S.

The directional transport of the phytohormone auxin represents a key, plant-specific mechanism for polarization and patterning in complex seed plants [2-5]. Here, we show that already in the early diverging land plant lineage, as exemplified by the moss Physcomitrella patens, auxin transport by PIN transporters is operational and diversified into ER-localized and plasma membrane-localized PIN proteins. Gain-of-function and loss-of-function analyses revealed that PIN-dependent intercellular auxin transport in Physcomitrella mediates crucial developmental transitions in tip-growing filaments and waves of polarization and differentiation in leaf-like structures. Plasma membrane PIN proteins localize in a polar manner to the tips of moss filaments, revealing an unexpected relation between polarization mechanisms in moss tip-growing cells and multicellular tissues of seed plants. Our results trace the origins of polarization and auxin-mediated patterning mechanisms and highlight the crucial role of polarized auxin transport during the evolution of multicellular land plants. author: - first_name: Tom full_name: Viaene, Tom last_name: Viaene - first_name: Katarina full_name: Landberg, Katarina last_name: Landberg - first_name: Mattias full_name: Thelander, Mattias last_name: Thelander - first_name: Eva full_name: Medvecka, Eva last_name: Medvecka - first_name: Eric full_name: Pederson, Eric last_name: Pederson - first_name: Elena full_name: Feraru, Elena last_name: Feraru - first_name: Endymion full_name: Cooper, Endymion last_name: Cooper - first_name: Mansour full_name: Karimi, Mansour last_name: Karimi - first_name: Charles full_name: Delwiche, Charles last_name: Delwiche - first_name: Karin full_name: Ljung, Karin last_name: Ljung - first_name: Markus full_name: Geisler, Markus last_name: Geisler - first_name: Eva full_name: Sundberg, Eva last_name: Sundberg - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Viaene T, Landberg K, Thelander M, et al.

In insect colonies, this protection is not restricted to the level of the individual organism, but also occurs at the societal level. Here, we review recent evidence for and insights into the mechanisms underlying individual and social immunisation in insects. We disentangle general immune-protective effects from specific immune memory (priming), and examine immunisation in the context of the lifetime of an individual and that of a colony, and of transgenerational immunisation that benefits offspring. When appropriate, we discuss parallels with disease defence strategies in human societies. We propose that recurrent parasitic threats have shaped the evolution of both the individual immune systems and colony-level social immunity in insects. acknowledgement: "This work was funded by an ERC Starting Grant by the European Research Council (to S.C.) and the ISTFELLOW program (Co-fund Marie Curie Actions of the European Commission; to L.M.).\r\nWe thank Christopher D.

However, how these cells are efficiently activated in the network remains unclear. To address this question, I performed recordings from CA1 pyramidal neuron axons, the presynaptic fibers that provide feedback innervation of these interneurons. Two forms of axonal action potential (AP) modulation were identified. First, repetitive stimulation resulted in activity-dependent AP broadening. Broadening showed fast onset, with marked changes in AP shape following a single AP. Second, tonic depolarization in CA1 pyramidal neuron somata induced AP broadening in the axon, and depolarization-induced broadening summated with activity-dependent broadening. Outsideout patch recordings from CA1 pyramidal neuron axons revealed a high density of a-dendrotoxin (α-DTX)-sensitive, inactivating K+ channels, suggesting that K+ channel inactivation mechanistically contributes to AP broadening. To examine the functional consequences of axonal AP modulation for synaptic transmission, I performed paired recordings between synaptically connected CA1 pyramidal neurons and O-LM interneurons. CA1 pyramidal neuron-O-LM interneuron excitatory postsynaptic currents (EPSCs) showed facilitation during both repetitive stimulation and tonic depolarization of the presynaptic neuron. Both effects were mimicked and occluded by α-DTX, suggesting that they were mediated by K+ channel inactivation. Therefore, axonal AP modulation can greatly facilitate the activation of O-LM interneurons. In conclusion, modulation of AP shape in CA1 pyramidal neuron axons substantially enhances the efficacy of principal neuron-interneuron synapses, promoting the activation of O-LM interneurons in recurrent inhibitory microcircuits. article_number: '0113124' author: - first_name: Sooyun full_name: Kim, Sooyun id: 394AB1C8-F248-11E8-B48F-1D18A9856A87 last_name: Kim citation: ama: Kim S.

(2008). Traditional statistical methods for confidentiality and privacy protection of statistical databases do not scale well to deal with GWAS data, especially in terms of guarantees regarding protection from linkage to external information. The more recent concept of differential privacy, introduced by the cryptographic community, is an approach that provides a rigorous definition of privacy with meaningful privacy guarantees in the presence of arbitrary external information, although the guarantees may come at a serious price in terms of data utility. Building on such notions, Uhler et al. (2013) proposed new methods to release aggregate GWAS data without compromising an individual’s privacy. We extend the methods developed in Uhler et al. (2013) for releasing differentially-private χ2χ2-statistics by allowing for arbitrary number of cases and controls, and for releasing differentially-private allelic test statistics. We also provide a new interpretation by assuming the controls’ data are known, which is a realistic assumption because some GWAS use publicly available data as controls. We assess the performance of the proposed methods through a risk-utility analysis on a real data set consisting of DNA samples collected by the Wellcome Trust Case Control Consortium and compare the methods with the differentially-private release mechanism proposed by Johnson and Shmatikov (2013). acknowledgement: This research was partially supported by NSF Awards EMSW21-RTG and BCS-0941518 to the Department of Statistics at Carnegie Mellon University, and by NSF Grant BCS-0941553 to the Department of Statistics at Pennsylvania State University.

Netrin-G1 and netrin-G2 are trans-synaptic adhesion molecules that distribute on distinct axons, and their presence restricts the expression of their cognate receptors, NGL1 and NGL2, respectively, to specific subdendritic segments of target neurons. However, the neural circuits and functional roles of netrin-G isoform complexes remain unclear. Here, we use netrin-G-KO and NGL-KO mice to reveal that netrin-G1/NGL1 and netrin-G2/NGL2 interactions specify excitatory synapses in independent hippocampal pathways. In the hippocampal CA1 area, netrin-G1/NGL1 and netrin-G2/NGL2 were expressed in the temporoammonic and Schaffer collateral pathways, respectively. The lack of presynaptic netrin-Gs led to the dispersion of NGLs from postsynaptic membranes. In accord, netrin-G mutant synapses displayed opposing phenotypes in long-term and short-term plasticity through discrete biochemical pathways. The plasticity phenotypes in netrin-G-KOs were phenocopied in NGL-KOs, with a corresponding loss of netrin-Gs from presynaptic membranes. Our findings show that netrin-G/NGL interactions differentially control synaptic plasticity in distinct circuits via retrograde signaling mechanisms and explain how synaptic inputs are diversified to control neuronal activity. acknowledgement: This work was supported by “Funding Program for World-Leading Innovative R&D on Science and Technology (FIRST Program)” initiated by the Council for Science and Technology Policy. article_processing_charge: No article_type: original author: - first_name: Hiroshi full_name: Matsukawa, Hiroshi last_name: Matsukawa - first_name: Sachiko full_name: Akiyoshi Nishimura, Sachiko last_name: Akiyoshi Nishimura - first_name: Qi full_name: Zhang, Qi last_name: Zhang - first_name: Rafael full_name: Luján, Rafael last_name: Luján - first_name: Kazuhiko full_name: Yamaguchi, Kazuhiko last_name: Yamaguchi - first_name: Hiromichi full_name: Goto, Hiromichi last_name: Goto - first_name: Kunio full_name: Yaguchi, Kunio last_name: Yaguchi - first_name: Tsutomu full_name: Hashikawa, Tsutomu last_name: Hashikawa - first_name: Chie full_name: Sano, Chie last_name: Sano - first_name: Ryuichi full_name: Shigemoto, Ryuichi id: 499F3ABC-F248-11E8-B48F-1D18A9856A87 last_name: Shigemoto orcid: 0000-0001-8761-9444 - first_name: Toshiaki full_name: Nakashiba, Toshiaki last_name: Nakashiba - first_name: Shigeyoshi full_name: Itohara, Shigeyoshi last_name: Itohara citation: ama: Matsukawa H, Akiyoshi Nishimura S, Zhang Q, et al.

This extends the recent results of Keating et al. (2014) that were proved for graphs with bounded chromatic number and with symmetric coupling distribution. Furthermore, we generalise the result to arbitrary hypergraphs. We test the optimality of our condition on the maximal degree for p-uniform hypergraphs that correspond to p-spin glass Hamiltonians acting on n distinguishable spin- 1/2 particles. At the critical threshold p = n1/2 we find a sharp classical-quantum phase transition between the normal distribution and the Wigner semicircle law. The former is characteristic to classical systems with commuting variables, while the latter is a signature of noncommutative random matrix theory. author: - first_name: László full_name: Erdös, László id: 4DBD5372-F248-11E8-B48F-1D18A9856A87 last_name: Erdös orcid: 0000-0001-5366-9603 - first_name: Dominik J full_name: Schröder, Dominik J last_name: Schröder citation: ama: Erdös L, Schröder DJ.

To gain insight into the patterns of RGP division and neuron production, we quantitatively analyzed excitatory neuron genesis in the mouse neocortex using Mosaic Analysis with Double Markers, which provides single-cell resolution of progenitor division patterns and potential in vivo. We found that RGPs progress through a coherent program in which their proliferative potential diminishes in a predictable manner. Upon entry into the neurogenic phase, individual RGPs produce ∼8–9 neurons distributed in both deep and superficial layers, indicating a unitary output in neuronal production. Removal of OTX1, a transcription factor transiently expressed in RGPs, results in both deep- and superficial-layer neuron loss and a reduction in neuronal unit size. Moreover, ∼1/6 of neurogenic RGPs proceed to produce glia. These results suggest that progenitor behavior and histogenesis in the mammalian neocortex conform to a remarkably orderly and deterministic program. author: - first_name: Peng full_name: Gao, Peng last_name: Gao - first_name: Maria P full_name: Postiglione, Maria P id: 2C67902A-F248-11E8-B48F-1D18A9856A87 last_name: Postiglione - first_name: Teresa full_name: Krieger, Teresa last_name: Krieger - first_name: Luisirene full_name: Hernandez, Luisirene last_name: Hernandez - first_name: Chao full_name: Wang, Chao last_name: Wang - first_name: Zhi full_name: Han, Zhi last_name: Han - first_name: Carmen full_name: Streicher, Carmen id: 36BCB99C-F248-11E8-B48F-1D18A9856A87 last_name: Streicher - first_name: Ekaterina full_name: Papusheva, Ekaterina id: 41DB591E-F248-11E8-B48F-1D18A9856A87 last_name: Papusheva - first_name: Ryan full_name: Insolera, Ryan last_name: Insolera - first_name: Kritika full_name: Chugh, Kritika last_name: Chugh - first_name: Oren full_name: Kodish, Oren last_name: Kodish - first_name: Kun full_name: Huang, Kun last_name: Huang - first_name: Benjamin full_name: Simons, Benjamin last_name: Simons - first_name: Liqun full_name: Luo, Liqun last_name: Luo - first_name: Simon full_name: Hippenmeyer, Simon id: 37B36620-F248-11E8-B48F-1D18A9856A87 last_name: Hippenmeyer orcid: 0000-0003-2279-1061 - first_name: Song full_name: Shi, Song last_name: Shi citation: ama: Gao P, Postiglione MP, Krieger T, et al.

Analysis of cell division in the mammalian heart is complicated by cardiomyocyte binucleation shortly after birth, which makes it challenging to interpret traditional assays of cell turnover [Laflamme MA, Murray CE (2011) Nature 473(7347):326–335; Bergmann O, et al. (2009) Science 324(5923):98–102]. An elegant multi-isotope imaging-mass spectrometry technique recently calculated the low, discrete rate of cardiomyocyte generation in mice [Senyo SE, et al. (2013) Nature 493(7432):433–436], yet our cellular-level understanding of postnatal cardiomyogenesis remains limited. Herein, we provide a new line of evidence for the differentiated α-myosin heavy chain-expressing cardiomyocyte as the cell of origin of postnatal cardiomyogenesis using the “mosaic analysis with double markers” mouse model. We show limited, life-long, symmetric division of cardiomyocytes as a rare event that is evident in utero but significantly diminishes after the first month of life in mice; daughter cardiomyocytes divide very seldom, which this study is the first to demonstrate, to our knowledge. Furthermore, ligation of the left anterior descending coronary artery, which causes a myocardial infarction in the mosaic analysis with double-marker mice, did not increase the rate of cardiomyocyte division above the basal level for up to 4 wk after the injury. The clonal analysis described here provides direct evidence of postnatal mammalian cardiomyogenesis. author: - first_name: Shah full_name: Ali, Shah last_name: Ali - first_name: Simon full_name: Hippenmeyer, Simon id: 37B36620-F248-11E8-B48F-1D18A9856A87 last_name: Hippenmeyer orcid: 0000-0003-2279-1061 - first_name: Lily full_name: Saadat, Lily last_name: Saadat - first_name: Liqun full_name: Luo, Liqun last_name: Luo - first_name: Irving full_name: Weissman, Irving last_name: Weissman - first_name: Reza full_name: Ardehali, Reza last_name: Ardehali citation: ama: Ali S, Hippenmeyer S, Saadat L, Luo L, Weissman I, Ardehali R.
