    Description: The recently released human genome sequences provide us with reference data to conduct comparative genomic research on primates, which will be important to understand what genetic information makes us human. Here we present a first-generation human-chimpanzee comparative genome map and its initial analysis. The map was constructed through paired alignment of 77,461 chimpanzee bacterial artificial chromosome end sequences with publicly available human genome sequences. We detected candidate positions, including two clusters on human chromosome 21 that suggest large, nonrandom regions of difference between the two genomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fujiyama, Asao -- Watanabe, Hidemi -- Toyoda, Atsushi -- Taylor, Todd D -- Itoh, Takehiko -- Tsai, Shih-Feng -- Park, Hong-Seog -- Yaspo, Marie-Laure -- Lehrach, Hans -- Chen, Zhu -- Fu, Gang -- Saitou, Naruya -- Osoegawa, Kazutoyo -- de Jong, Pieter J -- Suto, Yumiko -- Hattori, Masahira -- Sakaki, Yoshiyuki -- New York, N.Y. -- Science. 2002 Jan 4;295(5552):131-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉RIKEN Genomic Sciences Center, 1-7-22 Suehiro-cho, Tsurumi-ku, Yokohama, Kanagawa 230-0045, Japan. afujiyam@gsc.riken.go.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11778049" target="_blank"〉PubMed〈/a〉

    Description: To test the hypotheses of modern human origin in East Asia, we sampled 12,127 male individuals from 163 populations and typed for three Y chromosome biallelic markers (YAP, M89, and M130). All the individuals carried a mutation at one of the three sites. These three mutations (YAP+, M89T, and M130T) coalesce to another mutation (M168T), which originated in Africa about 35,000 to 89,000 years ago. Therefore, the data do not support even a minimal in situ hominid contribution in the origin of anatomically modern humans in East Asia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ke, Y -- Su, B -- Song, X -- Lu, D -- Chen, L -- Li, H -- Qi, C -- Marzuki, S -- Deka, R -- Underhill, P -- Xiao, C -- Shriver, M -- Lell, J -- Wallace, D -- Wells, R S -- Seielstad, M -- Oefner, P -- Zhu, D -- Jin, J -- Huang, W -- Chakraborty, R -- Chen, Z -- Jin, L -- New York, N.Y. -- Science. 2001 May 11;292(5519):1151-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉State Key Laboratory of Genetic Engineering, Institute of Genetics, School of Life Sciences, Fudan University, 220 Handan Road, Shanghai, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11349147" target="_blank"〉PubMed〈/a〉

    Description: A stable phase of toroidal, or ringlike, supramolecular assemblies was formed by combining dilute solution characteristics critical for both bundling of like-charged biopolymers and block copolymer micelle formation. The key to toroid versus classic cylinder micelle formation is the interaction of the negatively charged hydrophilic block of an amphiphilic triblock copolymer with a positively charged divalent organic counterion. This produces a self-attraction of cylindrical micelles that leads to toroid formation, a mechanism akin to the toroidal bundling of semiflexible charged biopolymers such as DNA. The toroids can be kinetically trapped or chemically cross-linked. Insight into the mechanism of toroid formation can be gained by observation of intermediate structures kinetically trapped during film casting.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pochan, Darrin J -- Chen, Zhiyun -- Cui, Honggang -- Hales, Kelly -- Qi, Kai -- Wooley, Karen L -- New York, N.Y. -- Science. 2004 Oct 1;306(5693):94-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Materials Science and Engineering and Delaware Biotechnology Institute, University of Delaware, Newark, DE 19716, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15459386" target="_blank"〉PubMed〈/a〉

    Description: We describe a simple process for the fabrication of ultrathin, transparent, optically homogeneous, electrically conducting films of pure single-walled carbon nanotubes and the transfer of those films to various substrates. For equivalent sheet resistance, the films exhibit optical transmittance comparable to that of commercial indium tin oxide in the visible spectrum, but far superior transmittance in the technologically relevant 2- to 5-micrometer infrared spectral band. These characteristics indicate broad applicability of the films for electrical coupling in photonic devices. In an example application, the films are used to construct an electric field-activated optical modulator, which constitutes an optical analog to the nanotube-based field effect transistor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, Zhuangchun -- Chen, Zhihong -- Du, Xu -- Logan, Jonathan M -- Sippel, Jennifer -- Nikolou, Maria -- Kamaras, Katalin -- Reynolds, John R -- Tanner, David B -- Hebard, Arthur F -- Rinzler, Andrew G -- New York, N.Y. -- Science. 2004 Aug 27;305(5688):1273-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physics, University of Florida, Gainesville, FL 32611, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15333836" target="_blank"〉PubMed〈/a〉

    Description: MicroRNAs (miRNAs) are an abundant class of approximately 22-nucleotide regulatory RNAs found in plants and animals. Some miRNAs of plants, Caenorhabditis elegans, and Drosophila play important gene-regulatory roles during development by pairing to target mRNAs to specify posttranscriptional repression of these messages. We identify three miRNAs that are specifically expressed in hematopoietic cells and show that their expression is dynamically regulated during early hematopoiesis and lineage commitment. One of these miRNAs, miR-181, was preferentially expressed in the B-lymphoid cells of mouse bone marrow, and its ectopic expression in hematopoietic stem/progenitor cells led to an increased fraction of B-lineage cells in both tissue-culture differentiation assays and adult mice. Our results indicate that microRNAs are components of the molecular circuitry that controls mouse hematopoiesis and suggest that other microRNAs have similar regulatory roles during other facets of vertebrate development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Chang-Zheng -- Li, Ling -- Lodish, Harvey F -- Bartel, David P -- R01 HL081612/HL/NHLBI NIH HHS/ -- R01 HL081612-01/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2004 Jan 2;303(5654):83-6.

    Description: Humans expressing a defective form of the transcription factor AIRE (autoimmune regulator) develop multiorgan autoimmune disease. We used aire- deficient mice to test the hypothesis that this transcription factor regulates autoimmunity by promoting the ectopic expression of peripheral tissue- restricted antigens in medullary epithelial cells of the thymus. This hypothesis proved correct. The mutant animals exhibited a defined profile of autoimmune diseases that depended on the absence of aire in stromal cells of the thymus. Aire-deficient thymic medullary epithelial cells showed a specific reduction in ectopic transcription of genes encoding peripheral antigens. These findings highlight the importance of thymically imposed "central" tolerance in controlling autoimmunity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anderson, Mark S -- Venanzi, Emily S -- Klein, Ludger -- Chen, Zhibin -- Berzins, Stuart P -- Turley, Shannon J -- von Boehmer, Harald -- Bronson, Roderick -- Dierich, Andree -- Benoist, Christophe -- Mathis, Diane -- 2 P30 DK36836-16/DK/NIDDK NIH HHS/ -- 2T32 DK07260-26/DK/NIDDK NIH HHS/ -- KO8-DK59958-01A1/DK/NIDDK NIH HHS/ -- R01 DK60027-01/DK/NIDDK NIH HHS/ -- T32CA70083-05/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2002 Nov 15;298(5597):1395-401.

    Description: Insulin receptors are abundant in the central nervous system, but their roles remain elusive. Here we show that the insulin receptor functions in axon guidance. The Drosophila insulin receptor (DInR) is required for photoreceptor-cell (R-cell) axons to find their way from the retina to the brain during development of the visual system. DInR functions as a guidance receptor for the adapter protein Dock/Nck. This function is independent of Chico, the Drosophila insulin receptor substrate (IRS) homolog.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Song, Jianbo -- Wu, Lingling -- Chen, Zun -- Kohanski, Ronald A -- Pick, Leslie -- New York, N.Y. -- Science. 2003 Apr 18;300(5618):502-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Brookdale Department for Molecular, Cell, and Developmental Biology, Mount Sinai School of Medicine, One Gustave Levy Place, New York, NY 10029, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12702880" target="_blank"〉PubMed〈/a〉

    Description: Atrial fibrillation (AF) is a common cardiac arrhythmia whose molecular etiology is poorly understood. We studied a family with hereditary persistent AF and identified the causative mutation (S140G) in the KCNQ1 (KvLQT1) gene on chromosome 11p15.5. The KCNQ1 gene encodes the pore-forming alpha subunit of the cardiac I(Ks) channel (KCNQ1/KCNE1), the KCNQ1/KCNE2 and the KCNQ1/KCNE3 potassium channels. Functional analysis of the S140G mutant revealed a gain-of-function effect on the KCNQ1/KCNE1 and the KCNQ1/KCNE2 currents, which contrasts with the dominant negative or loss-of-function effects of the KCNQ1 mutations previously identified in patients with long QT syndrome. Thus, the S140G mutation is likely to initiate and maintain AF by reducing action potential duration and effective refractory period in atrial myocytes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Yi-Han -- Xu, Shi-Jie -- Bendahhou, Said -- Wang, Xiao-Liang -- Wang, Ying -- Xu, Wen-Yuan -- Jin, Hong-Wei -- Sun, Hao -- Su, Xiao-Yan -- Zhuang, Qi-Nan -- Yang, Yi-Qing -- Li, Yue-Bin -- Liu, Yi -- Xu, Hong-Ju -- Li, Xiao-Fei -- Ma, Ning -- Mou, Chun-Ping -- Chen, Zhu -- Barhanin, Jacques -- Huang, Wei -- New York, N.Y. -- Science. 2003 Jan 10;299(5604):251-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cardiology, Tongji Hospital, and Institute of Medical Genetics, Tongji University, 399 Xin Cun Road, Shanghai 200065, People's Republic of China. drchen@public7.sta.net.cn〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12522251" target="_blank"〉PubMed〈/a〉
