    Beschreibung: Vascular plants appeared ~410 million years ago, then diverged into several lineages of which only two survive: the euphyllophytes (ferns and seed plants) and the lycophytes. We report here the genome sequence of the lycophyte Selaginella moellendorffii (Selaginella), the first nonseed vascular plant genome reported. By comparing gene content in evolutionarily diverse taxa, we found that the transition from a gametophyte- to a sporophyte-dominated life cycle required far fewer new genes than the transition from a nonseed vascular to a flowering plant, whereas secondary metabolic genes expanded extensively and in parallel in the lycophyte and angiosperm lineages. Selaginella differs in posttranscriptional gene regulation, including small RNA regulation of repetitive elements, an absence of the trans-acting small interfering RNA pathway, and extensive RNA editing of organellar genes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3166216/" 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/PMC3166216/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Banks, Jo Ann -- Nishiyama, Tomoaki -- Hasebe, Mitsuyasu -- Bowman, John L -- Gribskov, Michael -- dePamphilis, Claude -- Albert, Victor A -- Aono, Naoki -- Aoyama, Tsuyoshi -- Ambrose, Barbara A -- Ashton, Neil W -- Axtell, Michael J -- Barker, Elizabeth -- Barker, Michael S -- Bennetzen, Jeffrey L -- Bonawitz, Nicholas D -- Chapple, Clint -- Cheng, Chaoyang -- Correa, Luiz Gustavo Guedes -- Dacre, Michael -- DeBarry, Jeremy -- Dreyer, Ingo -- Elias, Marek -- Engstrom, Eric M -- Estelle, Mark -- Feng, Liang -- Finet, Cedric -- Floyd, Sandra K -- Frommer, Wolf B -- Fujita, Tomomichi -- Gramzow, Lydia -- Gutensohn, Michael -- Harholt, Jesper -- Hattori, Mitsuru -- Heyl, Alexander -- Hirai, Tadayoshi -- Hiwatashi, Yuji -- Ishikawa, Masaki -- Iwata, Mineko -- Karol, Kenneth G -- Koehler, Barbara -- Kolukisaoglu, Uener -- Kubo, Minoru -- Kurata, Tetsuya -- Lalonde, Sylvie -- Li, Kejie -- Li, Ying -- Litt, Amy -- Lyons, Eric -- Manning, Gerard -- Maruyama, Takeshi -- Michael, Todd P -- Mikami, Koji -- Miyazaki, Saori -- Morinaga, Shin-ichi -- Murata, Takashi -- Mueller-Roeber, Bernd -- Nelson, David R -- Obara, Mari -- Oguri, Yasuko -- Olmstead, Richard G -- Onodera, Naoko -- Petersen, Bent Larsen -- Pils, Birgit -- Prigge, Michael -- Rensing, Stefan A -- Riano-Pachon, Diego Mauricio -- Roberts, Alison W -- Sato, Yoshikatsu -- Scheller, Henrik Vibe -- Schulz, Burkhard -- Schulz, Christian -- Shakirov, Eugene V -- Shibagaki, Nakako -- Shinohara, Naoki -- Shippen, Dorothy E -- Sorensen, Iben -- Sotooka, Ryo -- Sugimoto, Nagisa -- Sugita, Mamoru -- Sumikawa, Naomi -- Tanurdzic, Milos -- Theissen, Gunter -- Ulvskov, Peter -- Wakazuki, Sachiko -- Weng, Jing-Ke -- Willats, William W G T -- Wipf, Daniel -- Wolf, Paul G -- Yang, Lixing -- Zimmer, Andreas D -- Zhu, Qihui -- Mitros, Therese -- Hellsten, Uffe -- Loque, Dominique -- Otillar, Robert -- Salamov, Asaf -- Schmutz, Jeremy -- Shapiro, Harris -- Lindquist, Erika -- Lucas, Susan -- Rokhsar, Daniel -- Grigoriev, Igor V -- GM065383/GM/NIGMS NIH HHS/ -- GM84051/GM/NIGMS NIH HHS/ -- HG004164/HG/NHGRI NIH HHS/ -- R01 GM043644/GM/NIGMS NIH HHS/ -- R01 GM084051/GM/NIGMS NIH HHS/ -- R01 GM084051-01A1/GM/NIGMS NIH HHS/ -- R01 HG004164/HG/NHGRI NIH HHS/ -- R01 HG004164-02/HG/NHGRI NIH HHS/ -- R01 HG004164-03/HG/NHGRI NIH HHS/ -- R01 HG004164-04/HG/NHGRI NIH HHS/ -- T32 GM007757/GM/NIGMS NIH HHS/ -- T32-HG00035/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2011 May 20;332(6032):960-3. doi: 10.1126/science.1203810.

    Beschreibung: Decreased cardiac contractility is a central feature of systolic heart failure. Existing drugs increase cardiac contractility indirectly through signaling cascades but are limited by their mechanism-related adverse effects. To avoid these limitations, we previously developed omecamtiv mecarbil, a small-molecule, direct activator of cardiac myosin. Here, we show that it binds to the myosin catalytic domain and operates by an allosteric mechanism to increase the transition rate of myosin into the strongly actin-bound force-generating state. Paradoxically, it inhibits adenosine 5'-triphosphate turnover in the absence of actin, which suggests that it stabilizes an actin-bound conformation of myosin. In animal models, omecamtiv mecarbil increases cardiac function by increasing the duration of ejection without changing the rates of contraction. Cardiac myosin activation may provide a new therapeutic approach for systolic heart failure.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4090309/" 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/PMC4090309/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Malik, Fady I -- Hartman, James J -- Elias, Kathleen A -- Morgan, Bradley P -- Rodriguez, Hector -- Brejc, Katjusa -- Anderson, Robert L -- Sueoka, Sandra H -- Lee, Kenneth H -- Finer, Jeffrey T -- Sakowicz, Roman -- Baliga, Ramesh -- Cox, David R -- Garard, Marc -- Godinez, Guillermo -- Kawas, Raja -- Kraynack, Erica -- Lenzi, David -- Lu, Pu Ping -- Muci, Alexander -- Niu, Congrong -- Qian, Xiangping -- Pierce, Daniel W -- Pokrovskii, Maria -- Suehiro, Ion -- Sylvester, Sheila -- Tochimoto, Todd -- Valdez, Corey -- Wang, Wenyue -- Katori, Tatsuo -- Kass, David A -- Shen, You-Tang -- Vatner, Stephen F -- Morgans, David J -- 1-R43-HL-66647-1/HL/NHLBI NIH HHS/ -- R01 HL106511/HL/NHLBI NIH HHS/ -- R43 HL066647/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2011 Mar 18;331(6023):1439-43. doi: 10.1126/science.1200113.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Preclinical Research and Development, Cytokinetics, Inc., South San Francisco, CA 94080, USA. fmalik@cytokinetics.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21415352" target="_blank"〉PubMed〈/a〉

    Beschreibung: Satellite repeats in heterochromatin are transcribed into noncoding RNAs that have been linked to gene silencing and maintenance of chromosomal integrity. Using digital gene expression analysis, we showed that these transcripts are greatly overexpressed in mouse and human epithelial cancers. In 8 of 10 mouse pancreatic ductal adenocarcinomas (PDACs), pericentromeric satellites accounted for a mean 12% (range 1 to 50%) of all cellular transcripts, a mean 40-fold increase over that in normal tissue. In 15 of 15 human PDACs, alpha satellite transcripts were most abundant and HSATII transcripts were highly specific for cancer. Similar patterns were observed in cancers of the lung, kidney, ovary, colon, and prostate. Derepression of satellite transcripts correlated with overexpression of the long interspersed nuclear element 1 (LINE-1) retrotransposon and with aberrant expression of neuroendocrine-associated genes proximal to LINE-1 insertions. The overexpression of satellite transcripts in cancer may reflect global alterations in heterochromatin silencing and could potentially be useful as a biomarker for cancer detection.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3701432/" 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/PMC3701432/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ting, David T -- Lipson, Doron -- Paul, Suchismita -- Brannigan, Brian W -- Akhavanfard, Sara -- Coffman, Erik J -- Contino, Gianmarco -- Deshpande, Vikram -- Iafrate, A John -- Letovsky, Stan -- Rivera, Miguel N -- Bardeesy, Nabeel -- Maheswaran, Shyamala -- Haber, Daniel A -- CA129933/CA/NCI NIH HHS/ -- L30 CA142210/CA/NCI NIH HHS/ -- P01 CA117969/CA/NCI NIH HHS/ -- R01 CA129933/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Feb 4;331(6017):593-6. doi: 10.1126/science.1200801.

    Beschreibung: Cytotoxic chemotherapy targets elements common to all nucleated human cells, such as DNA and microtubules, yet it selectively kills tumor cells. Here we show that clinical response to these drugs correlates with, and may be partially governed by, the pretreatment proximity of tumor cell mitochondria to the apoptotic threshold, a property called mitochondrial priming. We used BH3 profiling to measure priming in tumor cells from patients with multiple myeloma, acute myelogenous and lymphoblastic leukemia, and ovarian cancer. This assay measures mitochondrial response to peptides derived from proapoptotic BH3 domains of proteins critical for death signaling to mitochondria. Patients with highly primed cancers exhibited superior clinical response to chemotherapy. In contrast, chemoresistant cancers and normal tissues were poorly primed. Manipulation of mitochondrial priming might enhance the efficacy of cytotoxic agents.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3280949/" 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/PMC3280949/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ni Chonghaile, Triona -- Sarosiek, Kristopher A -- Vo, Thanh-Trang -- Ryan, Jeremy A -- Tammareddi, Anupama -- Moore, Victoria Del Gaizo -- Deng, Jing -- Anderson, Kenneth C -- Richardson, Paul -- Tai, Yu-Tzu -- Mitsiades, Constantine S -- Matulonis, Ursula A -- Drapkin, Ronny -- Stone, Richard -- Deangelo, Daniel J -- McConkey, David J -- Sallan, Stephen E -- Silverman, Lewis -- Hirsch, Michelle S -- Carrasco, Daniel Ruben -- Letai, Anthony -- P01CA068484/CA/NCI NIH HHS/ -- P01CA139980/CA/NCI NIH HHS/ -- R01 CA129974/CA/NCI NIH HHS/ -- R01 CA129974-05/CA/NCI NIH HHS/ -- R01CA129974/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2011 Nov 25;334(6059):1129-33. doi: 10.1126/science.1206727.

    Beschreibung: Immunosuppressive tumor microenvironments can restrain antitumor immunity, particularly in pancreatic ductal adenocarcinoma (PDA). Because CD40 activation can reverse immune suppression and drive antitumor T cell responses, we tested the combination of an agonist CD40 antibody with gemcitabine chemotherapy in a small cohort of patients with surgically incurable PDA and observed tumor regressions in some patients. We reproduced this treatment effect in a genetically engineered mouse model of PDA and found unexpectedly that tumor regression required macrophages but not T cells or gemcitabine. CD40-activated macrophages rapidly infiltrated tumors, became tumoricidal, and facilitated the depletion of tumor stroma. Thus, cancer immune surveillance does not necessarily depend on therapy-induced T cells; rather, our findings demonstrate a CD40-dependent mechanism for targeting tumor stroma in the treatment of cancer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3406187/" 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/PMC3406187/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Beatty, Gregory L -- Chiorean, Elena G -- Fishman, Matthew P -- Saboury, Babak -- Teitelbaum, Ursina R -- Sun, Weijing -- Huhn, Richard D -- Song, Wenru -- Li, Dongguang -- Sharp, Leslie L -- Torigian, Drew A -- O'Dwyer, Peter J -- Vonderheide, Robert H -- K08 CA138907/CA/NCI NIH HHS/ -- K12 CA076931/CA/NCI NIH HHS/ -- P30 CA016520/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2011 Mar 25;331(6024):1612-6. doi: 10.1126/science.1198443.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Abramson Family Cancer Research Institute, University of Pennsylvania School of Medicine, 421 Curie Boulevard, Philadelphia, PA 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21436454" target="_blank"〉PubMed〈/a〉

    Beschreibung: Environmental change has been observed to generate simultaneous responses in population dynamics, life history, gene frequencies, and morphology in a number of species. But how common are such eco-evolutionary responses to environmental change likely to be? Are they inevitable, or do they require a specific type of change? Can we accurately predict eco-evolutionary responses? We address these questions using theory and data from the study of Yellowstone wolves. We show that environmental change is expected to generate eco-evolutionary change, that changes in the average environment will affect wolves to a greater extent than changes in how variable it is, and that accurate prediction of the consequences of environmental change will probably prove elusive.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Coulson, Tim -- MacNulty, Daniel R -- Stahler, Daniel R -- vonHoldt, Bridgett -- Wayne, Robert K -- Smith, Douglas W -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2011 Dec 2;334(6060):1275-8. doi: 10.1126/science.1209441.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Life Sciences, Imperial College London, Silwood Park, Ascot, SL5 7PY, UK. t.coulson@imperial.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22144626" target="_blank"〉PubMed〈/a〉

    Beschreibung: Oligodendrogliomas are the second most common malignant brain tumor in adults and exhibit characteristic losses of chromosomes 1p and 19q. To identify the molecular genetic basis for this alteration, we performed exomic sequencing of seven tumors. Among other changes, we found that the CIC gene (homolog of the Drosophila gene capicua) on chromosome 19q was somatically mutated in six cases and that the FUBP1 gene [encoding far-upstream element (FUSE) binding protein] on chromosome 1p was somatically mutated in two tumors. Examination of 27 additional oligodendrogliomas revealed 12 and 3 more tumors with mutations of CIC and FUBP1, respectively, 58% of which were predicted to result in truncations of the encoded proteins. These results suggest a critical role for these genes in the biology and pathology of oligodendrocytes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3170506/" 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/PMC3170506/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bettegowda, Chetan -- Agrawal, Nishant -- Jiao, Yuchen -- Sausen, Mark -- Wood, Laura D -- Hruban, Ralph H -- Rodriguez, Fausto J -- Cahill, Daniel P -- McLendon, Roger -- Riggins, Gregory -- Velculescu, Victor E -- Oba-Shinjo, Sueli Mieko -- Marie, Suely Kazue Nagahashi -- Vogelstein, Bert -- Bigner, Darell -- Yan, Hai -- Papadopoulos, Nickolas -- Kinzler, Kenneth W -- CA11898/CA/NCI NIH HHS/ -- CA121113/CA/NCI NIH HHS/ -- CA43460/CA/NCI NIH HHS/ -- CA57345/CA/NCI NIH HHS/ -- CA62924/CA/NCI NIH HHS/ -- N01 CN043302/CN/NCI NIH HHS/ -- N01-CN-43302/CN/NCI NIH HHS/ -- NS20023/NS/NINDS NIH HHS/ -- P50 CA062924/CA/NCI NIH HHS/ -- P50 CA062924-06/CA/NCI NIH HHS/ -- P50 NS020023/NS/NINDS NIH HHS/ -- P50 NS020023-16/NS/NINDS NIH HHS/ -- R01 CA057345/CA/NCI NIH HHS/ -- R01 CA057345-08/CA/NCI NIH HHS/ -- R01 CA121113/CA/NCI NIH HHS/ -- R01 CA121113-01/CA/NCI NIH HHS/ -- R01 CA140316/CA/NCI NIH HHS/ -- R37 CA043460/CA/NCI NIH HHS/ -- R37 CA043460-16/CA/NCI NIH HHS/ -- R37 CA057345/CA/NCI NIH HHS/ -- RC2 DE020957/DE/NIDCR NIH HHS/ -- RC2 DE020957-01/DE/NIDCR NIH HHS/ -- RC2DE020957/DE/NIDCR NIH HHS/ -- T32 CA009574/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Sep 9;333(6048):1453-5. doi: 10.1126/science.1210557.

    Beschreibung: Black bears hibernate for 5 to 7 months a year and, during this time, do not eat, drink, urinate, or defecate. We measured metabolic rate and body temperature in hibernating black bears and found that they suppress metabolism to 25% of basal rates while regulating body temperature from 30 degrees to 36 degrees C, in multiday cycles. Heart rates were reduced from 55 to as few as 9 beats per minute, with profound sinus arrhythmia. After returning to normal body temperature and emerging from dens, bears maintained a reduced metabolic rate for up to 3 weeks. The pronounced reduction and delayed recovery of metabolic rate in hibernating bears suggest that the majority of metabolic suppression during hibernation is independent of lowered body temperature.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Toien, Oivind -- Blake, John -- Edgar, Dale M -- Grahn, Dennis A -- Heller, H Craig -- Barnes, Brian M -- HD-00973/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2011 Feb 18;331(6019):906-9. doi: 10.1126/science.1199435.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Arctic Biology, University of Alaska Fairbanks, Fairbanks, AK 99775, USA. otoien@alaska.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21330544" target="_blank"〉PubMed〈/a〉

    Beschreibung: The gain, loss, and modification of gene regulatory elements may underlie a substantial proportion of phenotypic changes on animal lineages. To investigate the gain of regulatory elements throughout vertebrate evolution, we identified genome-wide sets of putative regulatory regions for five vertebrates, including humans. These putative regulatory regions are conserved nonexonic elements (CNEEs), which are evolutionarily conserved yet do not overlap any coding or noncoding mature transcript. We then inferred the branch on which each CNEE came under selective constraint. Our analysis identified three extended periods in the evolution of gene regulatory elements. Early vertebrate evolution was characterized by regulatory gains near transcription factors and developmental genes, but this trend was replaced by innovations near extracellular signaling genes, and then innovations near posttranslational protein modifiers.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3511857/" 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/PMC3511857/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lowe, Craig B -- Kellis, Manolis -- Siepel, Adam -- Raney, Brian J -- Clamp, Michele -- Salama, Sofie R -- Kingsley, David M -- Lindblad-Toh, Kerstin -- Haussler, David -- 1U01-HG004695/HG/NHGRI NIH HHS/ -- 5P41-HG002371/HG/NHGRI NIH HHS/ -- P41 HG002371/HG/NHGRI NIH HHS/ -- P50 HG002568/HG/NHGRI NIH HHS/ -- P50-HG02568/HG/NHGRI NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- R01-HG004037/HG/NHGRI NIH HHS/ -- U01 HG004695/HG/NHGRI NIH HHS/ -- U54 HG003067/HG/NHGRI NIH HHS/ -- U54-HG003067/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Aug 19;333(6045):1019-24. doi: 10.1126/science.1202702.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Biomolecular Science and Engineering, University of California, Santa Cruz, CA 95064, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21852499" target="_blank"〉PubMed〈/a〉

    Beschreibung: A sexually mature individual of Darwinopterus preserved together with an egg from the Jurassic of China provides direct evidence of gender in pterosaurs and insights into the reproductive biology of these extinct fliers. This new find and several other examples of Darwinopterus demonstrate that males of this pterosaur had a relatively small pelvis and a large cranial crest, whereas females had a relatively large pelvis and no crest. The ratio of egg mass to adult mass is relatively low, as in extant reptiles, and is comparable to values for squamates. A parchment-like eggshell points to burial and significant uptake of water after oviposition. This evidence for low parental investment contradicts the widespread assumption that reproduction in pterosaurs was like that of birds and shows that it was essentially like that of reptiles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lu, Junchang -- Unwin, David M -- Deeming, D Charles -- Jin, Xingsheng -- Liu, Yongqing -- Ji, Qiang -- New York, N.Y. -- Science. 2011 Jan 21;331(6015):321-4. doi: 10.1126/science.1197323.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Geology, Chinese Academy of Geological Sciences, Beijing 100037, China. lujc2008@126.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21252343" target="_blank"〉PubMed〈/a〉
