    Description: Many bacterial pathogens encode a multisubunit toxin, termed cytolethal distending toxin (CDT), that induces cell cycle arrest, cytoplasm distention, and, eventually, chromatin fragmentation and cell death. In one such pathogen, Campylobacter jejuni, one of the subunits of this toxin, CdtB, was shown to exhibit features of type I deoxyribonucleases. Transient expression of this subunit in cultured cells caused marked chromatin disruption. Microinjection of low amounts of CdtB induced cytoplasmic distention and cell cycle arrest. CdtB mutants with substitutions in residues equivalent to those required for catalysis or magnesium binding in type I deoxyribonucleases did not cause chromatin disruption. CDT holotoxin containing these mutant forms of CdtB did not induce morphological changes or cell cycle arrest.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lara-Tejero, M -- Galan, J E -- New York, N.Y. -- Science. 2000 Oct 13;290(5490):354-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Microbial Pathogenesis, Boyer Center for Molecular Medicine, Yale School of Medicine, New Haven, CT 06536, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11030657" target="_blank"〉PubMed〈/a〉

    Description: The discovery of a living coelacanth specimen in 1938 was remarkable, as this lineage of lobe-finned fish was thought to have become extinct 70 million years ago. The modern coelacanth looks remarkably similar to many of its ancient relatives, and its evolutionary proximity to our own fish ancestors provides a glimpse of the fish that first walked on land. Here we report the genome sequence of the African coelacanth, Latimeria chalumnae. Through a phylogenomic analysis, we conclude that the lungfish, and not the coelacanth, is the closest living relative of tetrapods. Coelacanth protein-coding genes are significantly more slowly evolving than those of tetrapods, unlike other genomic features. Analyses of changes in genes and regulatory elements during the vertebrate adaptation to land highlight genes involved in immunity, nitrogen excretion and the development of fins, tail, ear, eye, brain and olfaction. Functional assays of enhancers involved in the fin-to-limb transition and in the emergence of extra-embryonic tissues show the importance of the coelacanth genome as a blueprint for understanding tetrapod evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3633110/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3633110/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Amemiya, Chris T -- Alfoldi, Jessica -- Lee, Alison P -- Fan, Shaohua -- Philippe, Herve -- Maccallum, Iain -- Braasch, Ingo -- Manousaki, Tereza -- Schneider, Igor -- Rohner, Nicolas -- Organ, Chris -- Chalopin, Domitille -- Smith, Jeramiah J -- Robinson, Mark -- Dorrington, Rosemary A -- Gerdol, Marco -- Aken, Bronwen -- Biscotti, Maria Assunta -- Barucca, Marco -- Baurain, Denis -- Berlin, Aaron M -- Blatch, Gregory L -- Buonocore, Francesco -- Burmester, Thorsten -- Campbell, Michael S -- Canapa, Adriana -- Cannon, John P -- Christoffels, Alan -- De Moro, Gianluca -- Edkins, Adrienne L -- Fan, Lin -- Fausto, Anna Maria -- Feiner, Nathalie -- Forconi, Mariko -- Gamieldien, Junaid -- Gnerre, Sante -- Gnirke, Andreas -- Goldstone, Jared V -- Haerty, Wilfried -- Hahn, Mark E -- Hesse, Uljana -- Hoffmann, Steve -- Johnson, Jeremy -- Karchner, Sibel I -- Kuraku, Shigehiro -- Lara, Marcia -- Levin, Joshua Z -- Litman, Gary W -- Mauceli, Evan -- Miyake, Tsutomu -- Mueller, M Gail -- Nelson, David R -- Nitsche, Anne -- Olmo, Ettore -- Ota, Tatsuya -- Pallavicini, Alberto -- Panji, Sumir -- Picone, Barbara -- Ponting, Chris P -- Prohaska, Sonja J -- Przybylski, Dariusz -- Saha, Nil Ratan -- Ravi, Vydianathan -- Ribeiro, Filipe J -- Sauka-Spengler, Tatjana -- Scapigliati, Giuseppe -- Searle, Stephen M J -- Sharpe, Ted -- Simakov, Oleg -- Stadler, Peter F -- Stegeman, John J -- Sumiyama, Kenta -- Tabbaa, Diana -- Tafer, Hakim -- Turner-Maier, Jason -- van Heusden, Peter -- White, Simon -- Williams, Louise -- Yandell, Mark -- Brinkmann, Henner -- Volff, Jean-Nicolas -- Tabin, Clifford J -- Shubin, Neil -- Schartl, Manfred -- Jaffe, David B -- Postlethwait, John H -- Venkatesh, Byrappa -- Di Palma, Federica -- Lander, Eric S -- Meyer, Axel -- Lindblad-Toh, Kerstin -- 095908/Wellcome Trust/United Kingdom -- MC_U137761446/Medical Research Council/United Kingdom -- P42 ES007381/ES/NIEHS NIH HHS/ -- R01 ES006272/ES/NIEHS NIH HHS/ -- R01 HG003474/HG/NHGRI NIH HHS/ -- R01 OD011116/OD/NIH HHS/ -- R24 OD011199/OD/NIH HHS/ -- R24 RR032670/RR/NCRR NIH HHS/ -- R37 HD032443/HD/NICHD NIH HHS/ -- U54 HG003067/HG/NHGRI NIH HHS/ -- England -- Nature. 2013 Apr 18;496(7445):311-6. doi: 10.1038/nature12027.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Genetics Program, Benaroya Research Institute, Seattle, Washington 98101, USA. camemiya@benaroyaresearch.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23598338" target="_blank"〉PubMed〈/a〉

    Description: The evolution of the amniotic egg was one of the great evolutionary innovations in the history of life, freeing vertebrates from an obligatory connection to water and thus permitting the conquest of terrestrial environments. Among amniotes, genome sequences are available for mammals and birds, but not for non-avian reptiles. Here we report the genome sequence of the North American green anole lizard, Anolis carolinensis. We find that A. carolinensis microchromosomes are highly syntenic with chicken microchromosomes, yet do not exhibit the high GC and low repeat content that are characteristic of avian microchromosomes. Also, A. carolinensis mobile elements are very young and diverse-more so than in any other sequenced amniote genome. The GC content of this lizard genome is also unusual in its homogeneity, unlike the regionally variable GC content found in mammals and birds. We describe and assign sequence to the previously unknown A. carolinensis X chromosome. Comparative gene analysis shows that amniote egg proteins have evolved significantly more rapidly than other proteins. An anole phylogeny resolves basal branches to illuminate the history of their repeated adaptive radiations.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3184186/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3184186/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alfoldi, Jessica -- Di Palma, Federica -- Grabherr, Manfred -- Williams, Christina -- Kong, Lesheng -- Mauceli, Evan -- Russell, Pamela -- Lowe, Craig B -- Glor, Richard E -- Jaffe, Jacob D -- Ray, David A -- Boissinot, Stephane -- Shedlock, Andrew M -- Botka, Christopher -- Castoe, Todd A -- Colbourne, John K -- Fujita, Matthew K -- Moreno, Ricardo Godinez -- ten Hallers, Boudewijn F -- Haussler, David -- Heger, Andreas -- Heiman, David -- Janes, Daniel E -- Johnson, Jeremy -- de Jong, Pieter J -- Koriabine, Maxim Y -- Lara, Marcia -- Novick, Peter A -- Organ, Chris L -- Peach, Sally E -- Poe, Steven -- Pollock, David D -- de Queiroz, Kevin -- Sanger, Thomas -- Searle, Steve -- Smith, Jeremy D -- Smith, Zachary -- Swofford, Ross -- Turner-Maier, Jason -- Wade, Juli -- Young, Sarah -- Zadissa, Amonida -- Edwards, Scott V -- Glenn, Travis C -- Schneider, Christopher J -- Losos, Jonathan B -- Lander, Eric S -- Breen, Matthew -- Ponting, Chris P -- Lindblad-Toh, Kerstin -- BB/F007590/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- MC_U137761446/Medical Research Council/United Kingdom -- U54 HG003067/HG/NHGRI NIH HHS/ -- U54 HG003067-08/HG/NHGRI NIH HHS/ -- England -- Nature. 2011 Aug 31;477(7366):587-91. doi: 10.1038/nature10390.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Broad Institute of MIT and Harvard, Cambridge, Massachusetts 02142, USA. jalfoldi@broadinstitute.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21881562" target="_blank"〉PubMed〈/a〉

    Description: Bacterial type III protein secretion systems deliver effector proteins into eukaryotic cells in order to modulate cellular processes. Central to the function of these protein-delivery machines is their ability to recognize and secrete substrates in a defined order. Here, we describe a mechanism by which a type III secretion system from the bacterial enteropathogen Salmonella enterica serovar Typhimurium can sort its substrates before secretion. This mechanism involves a cytoplasmic sorting platform that is sequentially loaded with the appropriate secreted proteins. The sequential loading of this platform, facilitated by customized chaperones, ensures the hierarchy in type III protein secretion. Given the presence of these machines in many important pathogens, these findings can serve as the bases for the development of novel antimicrobial strategies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3859126/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3859126/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lara-Tejero, Maria -- Kato, Junya -- Wagner, Samuel -- Liu, Xiaoyun -- Galan, Jorge E -- AI30492/AI/NIAID NIH HHS/ -- R01 AI030492/AI/NIAID NIH HHS/ -- U54 AI0157158/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2011 Mar 4;331(6021):1188-91. doi: 10.1126/science.1201476.

    Description: Los peces constituyen uno de los atractivos principales en los arrecifes coralinos para el buceoturístico, por lo cual resulta necesario monitorear su abundancia y valores estéticos. El objetivo de estainvestigación fue evaluar el estado de conservación de las asociaciones de peces arrecifales en cuatro delos principales polos turísticos del Archipiélago Sabana-Camagüey, Cuba en el año 2010. Semuestrearon 23 sitios de buceo turísticos en áreas adyacentes a las regiones de Varadero (5 sitios),cayos de Villa Clara (6 sitios), Cayo Coco (6 sitios) y Santa Lucia (6 sitios). En cada uno de ellos serealizaron seis réplicas de censos visuales de todas las especies de peces en recorridos lineales de 50 mde largo por 2 m de ancho, ocupando un área total de 600 m2. El puntaje más alto de conservación lopresentó los cayos de Villa Clara (37), siguiéndole en orden decreciente Cayo Coco (35), y con valoresmás bajos Varadero (24) y Santa Lucia (22). Los puntajes de las cuatro regiones fueron inferiores a losencontrados en otros arrecifes de Cuba y el Caribe. Los valores de Varadero y Santa Lucia secorrespondieron con los de arrecifes de hábitats degradados y sometidos a explotación pesquera. Engeneral, en la mayoría de las regiones predominaron peces de talla pequeña (〈20 cm) pertenecientes alas familias Pomacentridae y Labridae y hubo poca abundancia de peces carnívoros y herbívoros demediana (20-40 cm) y gran talla (〉40 cm).ABSTRACTFish are one of the main attractions on coral reefs for diving tourism; therefore, it is necessary tomonitor their condition and aesthetic values. The objective of this research was to evaluate the status ofreef fish assemblages in four tourist areas of Sabana-Camaguey Archipelago, Cuba in 2010. Twentythreetourist diving sites were sampled in adjacent areas to regions of Varadero (five sites), Villa Clarakeys (6 sites), Coco key (6 sites) and Santa Lucia (6 sites). In each region, six replicated visual census ofall fish species were conducted along belt transects of 50 m length and 2 m width, occupying a total areaof 600 m2. The highest conservation score was obtained by Villa Clara keys (37), followed in decreasingorder by Coco key (35), and with lower values Varadero (24) and St. Lucia (22). The scores of the fourregions were lower than the values of other Cuban and Caribbean reefs. The values of Varadero andSanta Lucia corresponded to reefs with degraded habitats and subject to overfishing. In general, small fish(〈 20 cm) from families Pomacentridae and Labridae, and low abundance of carnivore and herbivore fishof middle (20-40 cm) and large size (〉 40 cm) predominated in most regions.

    Description: RESUMENSe comparó el grado de resiliencia de seis crestas arrecifales del este del golfo de Batabanó, Cuba. Tres fueron del norte del golfo de Cazones (Tramo Norte) y las restantes, del oeste de Cayo Largo (Tramo Sur). Las del primer tramo fueron las de faro Cazones, Norte de la cresta de cayo Diego Pérez y de faro Diego Pérez. Las otras tres fueron las de cayo Rico, arrecifes Los Ballenatos y arrecifes Hijos de Los Ballenatos. Se emplearon los indicadores biológicos del Protocolo AGRRA. El Tramo Norte presentó las crestas más resilientes, sobre todo la de faro Cazones. Las del Tramo Sur no exhibieron resiliencia. Fueron varios e interrelacionados, los factores aparentemente más determinantes en la resiliencia. Entre estos, cuatro se consideraron como fuerzas motrices: resguardo contra el oleaje, circulación habitual giratoria ciclónica en la ensenada de Cazones, entrada de nutrientes provenientes tanto de la ciénaga de Zapata como de aguas profundas, y abundancia del erizo herbívoro Diadema antillarum. Los demás factores, desencadenados por los anteriores y también interrelacionados, fueron, al parecer la menor afectación por oleaje y sedimentos, estabilización de fragmentos vivos de coral, índices favorables de macroalgas bentónicas, cierta retención de nutrientes y plancton, más alimentación heterotrófica de los corales, mayor auto reclutamiento de corales y del erizo Diadema; mejores condiciones para el asentamiento y viabilidad de los reclutas, y para el recapamiento de corales; mayor crecimiento y recuperación de los corales y mejores condiciones térmicas contra el blanqueamiento de coralesABSTRACTThe degree of resilience of six reef crest sites was compared at the east of the Gulf of Batabano, Cuba. Three of them were located north of the Gulf of Cazones (Northern Stretch), while the remaining ones were west of Cayo Largo (Southern Stretch). Those of the Northern Stretch were “Faro Cazones”, north of the crest of cayo Diego Pérez and “Faro Diego Pérez”. The remaining sites were those of the cayo Rico, Los Ballenatos reefs, and Hijos de Los Ballenatos reefs. The AGRRA biological indicators were applied. The Northern Stretch presented the most resilient crests, mainly that of “Faro Cazones”. Those of the Southern Stretch did not reveal signs of resilience. Several interrelated factors were apparently more linked to resilience. Four of them were considered as driving forces: shelter from waves, usual cyclonic revolving water circulation in the Ensenada de Cazones, nutrient input from the Zapata swamp and deep water, and the abundance of the herbivore sea urchin Diadema antillarum. Triggered by these driving forces, the remaining factors apparently were less effect of waves and sediments, stabilization of live coral fragments, favorable benthic macro-algae indices, some retention of nutrient and plankton, increased coral heterotrophic feeding; better conditions for recruit settlement and viability, and for coral re-sheeting; faster coral growth and recuperation and better thermal conditions against coral bleaching.
