    Description: Efficient electrophilic metalation of aromatic C-H bonds leading to new C-C bond formation through regio- and stereoselective addition to alkynes and alkenes has been realized by a catalytic amount (0.02 to 5 mole percent) of palladium(II) or platinum(II) compounds in a mixed solvent containing trifluoroacetic acid at room temperature. Various arenes undergo unexpected selective trans hydroarylation to terminal or internal C&cjs0812;C bonds inter- and intramolecularly with high efficiency (up to a turnover number of 4500 for palladium), especially for electron-rich arenes, giving thermodynamically unfavorable cis-alkenes, and the oxygen- and nitrogen-containing heterocycles. The simplicity, generality, and efficiency of this process should be very attractive to the possible industrial application for the functionalization of arenes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jia -- Piao -- Oyamada -- Lu -- Kitamura -- Fujiwara -- New York, N.Y. -- Science. 2000 Mar 17;287(5460):1992-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biochemistry, Graduate School of Engineering, Kyushu University, Hakozaki, Fukuoka, 812-8581, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10720319" target="_blank"〉PubMed〈/a〉

    Description: Neurotrophins such as brain-derived neurotrophic factor (BDNF) are thought to be transferred from post- to presynaptic neurons and to be involved in the formation and plasticity of neural circuits. However, direct evidence for a transneuronal transfer of BDNF and its relation to neuronal activity remains elusive. We simultaneously injected complementary DNAs of green fluorescent protein (GFP)-tagged BDNF and red fluorescence protein into the nucleus of single neurons and visualized expression, localization, and transport of BDNF in living neurons. Fluorescent puncta representing BDNF moved in axons in the anterograde direction, though some moved retrogradely, and transferred to postsynaptic neurons in an activity-dependent manner.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kohara, K -- Kitamura, A -- Morishima, M -- Tsumoto, T -- New York, N.Y. -- Science. 2001 Mar 23;291(5512):2419-23.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Neurophysiology, Biomedical Research Center, Osaka University Graduate School of Medicine, 2-2 Yamadaoka, Suita, Osaka 565-0871 Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11264540" target="_blank"〉PubMed〈/a〉

    Description: Axon guidance proteins are critical for the correct wiring of the nervous system during development. Several axon guidance cues and their family members have been well characterized. More unidentified axon guidance cues are assumed to participate in the formation of the extremely complex nervous system. We identified a secreted protein, draxin, that shares no homology with known guidance cues. Draxin inhibited or repelled neurite outgrowth from dorsal spinal cord and cortical explants in vitro. Ectopically expressed draxin inhibited growth or caused misrouting of chick spinal cord commissural axons in vivo. draxin knockout mice showed defasciculation of spinal cord commissural axons and absence of all forebrain commissures. Thus, draxin is a previously unknown chemorepulsive axon guidance molecule required for the development of spinal cord and forebrain commissures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Islam, Shahidul M -- Shinmyo, Yohei -- Okafuji, Tatsuya -- Su, Yuhong -- Naser, Iftekhar Bin -- Ahmed, Giasuddin -- Zhang, Sanbing -- Chen, Sandy -- Ohta, Kunimasa -- Kiyonari, Hiroshi -- Abe, Takaya -- Tanaka, Satomi -- Nishinakamura, Ryuichi -- Terashima, Toshio -- Kitamura, Toshio -- Tanaka, Hideaki -- New York, N.Y. -- Science. 2009 Jan 16;323(5912):388-93. doi: 10.1126/science.1165187.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Developmental Neurobiology, Graduate School of Medical Sciences, Kumamoto University, 1-1-1 Honjo, Kumamoto 860-8556, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19150847" target="_blank"〉PubMed〈/a〉

    Description: Synaptic inputs on dendrites are nonlinearly converted to action potential outputs, yet the spatiotemporal patterns of dendritic activation remain to be elucidated at single-synapse resolution. In rodents, we optically imaged synaptic activities from hundreds of dendritic spines in hippocampal and neocortical pyramidal neurons ex vivo and in vivo. Adjacent spines were frequently synchronized in spontaneously active networks, thereby forming dendritic foci that received locally convergent inputs from presynaptic cell assemblies. This precise subcellular geometry manifested itself during N-methyl-D-aspartate receptor-dependent circuit remodeling. Thus, clustered synaptic plasticity is innately programmed to compartmentalize correlated inputs along dendrites and may reify nonlinear synaptic integration.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takahashi, Naoya -- Kitamura, Kazuo -- Matsuo, Naoki -- Mayford, Mark -- Kano, Masanobu -- Matsuki, Norio -- Ikegaya, Yuji -- New York, N.Y. -- Science. 2012 Jan 20;335(6066):353-6. doi: 10.1126/science.1210362.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Chemical Pharmacology, Graduate School of Pharmaceutical Sciences, The University of Tokyo, Bunkyo-ku, Tokyo, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22267814" target="_blank"〉PubMed〈/a〉

    Description: Episodic memory requires associations of temporally discontiguous events. In the entorhinal-hippocampal network, temporal associations are driven by a direct pathway from layer III of the medial entorhinal cortex (MECIII) to the hippocampal CA1 region. However, the identification of neural circuits that regulate this association has remained unknown. In layer II of entorhinal cortex (ECII), we report clusters of excitatory neurons called island cells, which appear in a curvilinear matrix of bulblike structures, directly project to CA1, and activate interneurons that target the distal dendrites of CA1 pyramidal neurons. Island cells suppress the excitatory MECIII input through the feed-forward inhibition to control the strength and duration of temporal association in trace fear memory. Together, the two EC inputs compose a control circuit for temporal association memory.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kitamura, Takashi -- Pignatelli, Michele -- Suh, Junghyup -- Kohara, Keigo -- Yoshiki, Atsushi -- Abe, Kuniya -- Tonegawa, Susumu -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Feb 21;343(6173):896-901. doi: 10.1126/science.1244634.

    Description: This study describes comprehensive polling of transcription start and termination sites and analysis of previously unidentified full-length complementary DNAs derived from the mouse genome. We identify the 5' and 3' boundaries of 181,047 transcripts with extensive variation in transcripts arising from alternative promoter usage, splicing, and polyadenylation. There are 16,247 new mouse protein-coding transcripts, including 5154 encoding previously unidentified proteins. Genomic mapping of the transcriptome reveals transcriptional forests, with overlapping transcription on both strands, separated by deserts in which few transcripts are observed. The data provide a comprehensive platform for the comparative analysis of mammalian transcriptional regulation in differentiation and development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carninci, P -- Kasukawa, T -- Katayama, S -- Gough, J -- Frith, M C -- Maeda, N -- Oyama, R -- Ravasi, T -- Lenhard, B -- Wells, C -- Kodzius, R -- Shimokawa, K -- Bajic, V B -- Brenner, S E -- Batalov, S -- Forrest, A R R -- Zavolan, M -- Davis, M J -- Wilming, L G -- Aidinis, V -- Allen, J E -- Ambesi-Impiombato, A -- Apweiler, R -- Aturaliya, R N -- Bailey, T L -- Bansal, M -- Baxter, L -- Beisel, K W -- Bersano, T -- Bono, H -- Chalk, A M -- Chiu, K P -- Choudhary, V -- Christoffels, A -- Clutterbuck, D R -- Crowe, M L -- Dalla, E -- Dalrymple, B P -- de Bono, B -- Della Gatta, G -- di Bernardo, D -- Down, T -- Engstrom, P -- Fagiolini, M -- Faulkner, G -- Fletcher, C F -- Fukushima, T -- Furuno, M -- Futaki, S -- Gariboldi, M -- Georgii-Hemming, P -- Gingeras, T R -- Gojobori, T -- Green, R E -- Gustincich, S -- Harbers, M -- Hayashi, Y -- Hensch, T K -- Hirokawa, N -- Hill, D -- Huminiecki, L -- Iacono, M -- Ikeo, K -- Iwama, A -- Ishikawa, T -- Jakt, M -- Kanapin, A -- Katoh, M -- Kawasawa, Y -- Kelso, J -- Kitamura, H -- Kitano, H -- Kollias, G -- Krishnan, S P T -- Kruger, A -- Kummerfeld, S K -- Kurochkin, I V -- Lareau, L F -- Lazarevic, D -- Lipovich, L -- Liu, J -- Liuni, S -- McWilliam, S -- Madan Babu, M -- Madera, M -- Marchionni, L -- Matsuda, H -- Matsuzawa, S -- Miki, H -- Mignone, F -- Miyake, S -- Morris, K -- Mottagui-Tabar, S -- Mulder, N -- Nakano, N -- Nakauchi, H -- Ng, P -- Nilsson, R -- Nishiguchi, S -- Nishikawa, S -- Nori, F -- Ohara, O -- Okazaki, Y -- Orlando, V -- Pang, K C -- Pavan, W J -- Pavesi, G -- Pesole, G -- Petrovsky, N -- Piazza, S -- Reed, J -- Reid, J F -- Ring, B Z -- Ringwald, M -- Rost, B -- Ruan, Y -- Salzberg, S L -- Sandelin, A -- Schneider, C -- Schonbach, C -- Sekiguchi, K -- Semple, C A M -- Seno, S -- Sessa, L -- Sheng, Y -- Shibata, Y -- Shimada, H -- Shimada, K -- Silva, D -- Sinclair, B -- Sperling, S -- Stupka, E -- Sugiura, K -- Sultana, R -- Takenaka, Y -- Taki, K -- Tammoja, K -- Tan, S L -- Tang, S -- Taylor, M S -- Tegner, J -- Teichmann, S A -- Ueda, H R -- van Nimwegen, E -- Verardo, R -- Wei, C L -- Yagi, K -- Yamanishi, H -- Zabarovsky, E -- Zhu, S -- Zimmer, A -- Hide, W -- Bult, C -- Grimmond, S M -- Teasdale, R D -- Liu, E T -- Brusic, V -- Quackenbush, J -- Wahlestedt, C -- Mattick, J S -- Hume, D A -- Kai, C -- Sasaki, D -- Tomaru, Y -- Fukuda, S -- Kanamori-Katayama, M -- Suzuki, M -- Aoki, J -- Arakawa, T -- Iida, J -- Imamura, K -- Itoh, M -- Kato, T -- Kawaji, H -- Kawagashira, N -- Kawashima, T -- Kojima, M -- Kondo, S -- Konno, H -- Nakano, K -- Ninomiya, N -- Nishio, T -- Okada, M -- Plessy, C -- Shibata, K -- Shiraki, T -- Suzuki, S -- Tagami, M -- Waki, K -- Watahiki, A -- Okamura-Oho, Y -- Suzuki, H -- Kawai, J -- Hayashizaki, Y -- FANTOM Consortium -- RIKEN Genome Exploration Research Group and Genome Science Group (Genome Network Project Core Group) -- TGM03P17/Telethon/Italy -- TGM06S01/Telethon/Italy -- New York, N.Y. -- Science. 2005 Sep 2;309(5740):1559-63.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16141072" target="_blank"〉PubMed〈/a〉

    Description: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors in the human digestive tract, but their molecular etiology and cellular origin are unknown. Sequencing of c-kit complementary DNA, which encodes a proto-oncogenic receptor tyrosine kinase (KIT), from five GISTs revealed mutations in the region between the transmembrane and tyrosine kinase domains. All of the corresponding mutant KIT proteins were constitutively activated without the KIT ligand, stem cell factor (SCF). Stable transfection of the mutant c-kit complementary DNAs induced malignant transformation of Ba/F3 murine lymphoid cells, suggesting that the mutations contribute to tumor development. GISTs may originate from the interstitial cells of Cajal (ICCs) because the development of ICCs is dependent on the SCF-KIT interaction and because, like GISTs, these cells express both KIT and CD34.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hirota, S -- Isozaki, K -- Moriyama, Y -- Hashimoto, K -- Nishida, T -- Ishiguro, S -- Kawano, K -- Hanada, M -- Kurata, A -- Takeda, M -- Muhammad Tunio, G -- Matsuzawa, Y -- Kanakura, Y -- Shinomura, Y -- Kitamura, Y -- New York, N.Y. -- Science. 1998 Jan 23;279(5350):577-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Osaka University Medical School, Yamada-oka 2-2, Suita 565, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9438854" target="_blank"〉PubMed〈/a〉

    Description: Mott insulators can host a surprisingly diverse set of quantum phenomena when their frozen electrons are perturbed by various stimuli. Superconductivity, metal-insulator transition, and colossal magnetoresistance induced by element substitution, pressure, and magnetic field are prominent examples. Here we report strong diamagnetism in the Mott insulator calcium ruthenate (Ca 2 RuO 4 ) induced by dc electric current. The application of a current density of merely 1 ampere per centimeter squared induces diamagnetism stronger than that in other nonsuperconducting materials. This change is coincident with changes in the transport properties as the system becomes semimetallic. These findings suggest that dc current may be a means to control the properties of materials in the vicinity of a Mott insulating transition.

    Description: Platelet and fibrin clots occlude blood vessels in hemostasis and thrombosis. Here we report a noncanonical mechanism for vascular occlusion based on neutrophil extracellular traps (NETs), DNA fibers released by neutrophils during inflammation. We investigated which host factors control NETs in vivo and found that two deoxyribonucleases (DNases), DNase1 and DNase1-like 3, degraded NETs in circulation during sterile neutrophilia and septicemia. In the absence of both DNases, intravascular NETs formed clots that obstructed blood vessels and caused organ damage. Vascular occlusions in patients with severe bacterial infections were associated with a defect to degrade NETs ex vivo and the formation of intravascular NET clots. DNase1 and DNase1-like 3 are independently expressed and thus provide dual host protection against deleterious effects of intravascular NETs.
