    Description: The textbook description of mitochondrial respiratory complexes (RCs) views them as free-moving entities linked by the mobile carriers coenzyme Q (CoQ) and cytochrome c (cyt c). This model (known as the fluid model) is challenged by the proposal that all RCs except complex II can associate in supercomplexes (SCs). The proposed SCs are the respirasome (complexes I, III, and IV), complexes I and III, and complexes III and IV. The role of SCs is unclear, and their existence is debated. By genetic modulation of interactions between complexes I and III and III and IV, we show that these associations define dedicated CoQ and cyt c pools and that SC assembly is dynamic and organizes electron flux to optimize the use of available substrates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lapuente-Brun, Esther -- Moreno-Loshuertos, Raquel -- Acin-Perez, Rebeca -- Latorre-Pellicer, Ana -- Colas, Carmen -- Balsa, Eduardo -- Perales-Clemente, Ester -- Quiros, Pedro M -- Calvo, Enrique -- Rodriguez-Hernandez, M A -- Navas, Placido -- Cruz, Raquel -- Carracedo, Angel -- Lopez-Otin, Carlos -- Perez-Martos, Acisclo -- Fernandez-Silva, Patricio -- Fernandez-Vizarra, Erika -- Enriquez, Jose Antonio -- New York, N.Y. -- Science. 2013 Jun 28;340(6140):1567-70. doi: 10.1126/science.1230381.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centro Nacional de Investigaciones Cardiovasculares Carlos III, Madrid, Spain.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23812712" target="_blank"〉PubMed〈/a〉

    Description: Higher order chromatin structure presents a barrier to the recognition and repair of DNA damage. Double-strand breaks (DSBs) induce histone H2AX phosphorylation, which is associated with the recruitment of repair factors to damaged DNA. To help clarify the physiological role of H2AX, we targeted H2AX in mice. Although H2AX is not essential for irradiation-induced cell-cycle checkpoints, H2AX-/- mice were radiation sensitive, growth retarded, and immune deficient, and mutant males were infertile. These pleiotropic phenotypes were associated with chromosomal instability, repair defects, and impaired recruitment of Nbs1, 53bp1, and Brca1, but not Rad51, to irradiation-induced foci. Thus, H2AX is critical for facilitating the assembly of specific DNA-repair complexes on damaged DNA.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4721576/" 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/PMC4721576/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Celeste, Arkady -- Petersen, Simone -- Romanienko, Peter J -- Fernandez-Capetillo, Oscar -- Chen, Hua Tang -- Sedelnikova, Olga A -- Reina-San-Martin, Bernardo -- Coppola, Vincenzo -- Meffre, Eric -- Difilippantonio, Michael J -- Redon, Christophe -- Pilch, Duane R -- Olaru, Alexandru -- Eckhaus, Michael -- Camerini-Otero, R Daniel -- Tessarollo, Lino -- Livak, Ferenc -- Manova, Katia -- Bonner, William M -- Nussenzweig, Michel C -- Nussenzweig, Andre -- Z99 CA999999/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2002 May 3;296(5569):922-7.

    Description: Infections with Plasmodium falciparum during pregnancy lead to the accumulation of parasitized red blood cells (infected erythrocytes, IEs) in the placenta. IEs of P. falciparum isolates that infect the human placenta were found to bind immunoglobulin G (IgG). A strain of P. falciparum cloned for IgG binding adhered massively to placental syncytiotrophoblasts in a pattern similar to that of natural infections. Adherence was inhibited by IgG-binding proteins, but not by glycosaminoglycans or enzymatic digestion of chondroitin sulfate A or hyaluronic acid. Normal, nonimmune IgG that is bound to a duffy binding-like domain beta of the P. falciparum erythrocyte membrane protein 1 (PfEMP1) might at the IE surface act as a bridge to neonatal Fc receptors of the placenta.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Flick, K -- Scholander, C -- Chen, Q -- Fernandez, V -- Pouvelle, B -- Gysin, J -- Wahlgren, M -- New York, N.Y. -- Science. 2001 Sep 14;293(5537):2098-100.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Microbiology and Tumor Biology Center (MTC), Karolinska Institutet and Swedish Institute for Infectious Disease Control, Box 280, S-171 77 Stockholm, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11557894" target="_blank"〉PubMed〈/a〉

    Description: In mammals, ocular photoreceptors mediate an acute inhibition of pineal melatonin by light. The effect of rod and cone loss on this response was assessed by combining the rd mutation with a transgenic ablation of cones (cl) to produce mice lacking both photoreceptor classes. Despite the loss of all known retinal photoreceptors, rd/rd cl mice showed normal suppression of pineal melatonin in response to monochromatic light of wavelength 509 nanometers. These data indicate that mammals have additional ocular photoreceptors that they use in the regulation of temporal physiology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lucas, R J -- Freedman, M S -- Munoz, M -- Garcia-Fernandez, J M -- Foster, R G -- New York, N.Y. -- Science. 1999 Apr 16;284(5413):505-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Sir Alexander Fleming Building, Imperial College of Science, Technology and Medicine, London, SW7 2AZ, UK. r.j.lucas@ic.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10205062" target="_blank"〉PubMed〈/a〉

    Description: Parasites have evolved a plethora of mechanisms to ensure their propagation and evade antagonistic host responses. The intracellular protozoan parasite Theileria is the only eukaryote known to induce uncontrolled host cell proliferation. Survival of Theileria-transformed leukocytes depends strictly on constitutive nuclear factor kappa B (NF-kappaB) activity. We found that this was mediated by recruitment of the multisubunit IkappaB kinase (IKK) into large, activated foci on the parasite surface. IKK signalosome assembly was specific for the transforming schizont stage of the parasite and was down-regulated upon differentiation into the nontransforming merozoite stage. Our findings provide insights into IKK activation and how pathogens subvert host-cell signaling pathways.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heussler, Volker T -- Rottenberg, Sven -- Schwab, Rebekka -- Kuenzi, Peter -- Fernandez, Paula C -- McKellar, Susan -- Shiels, Brian -- Chen, Zhijian J -- Orth, Kim -- Wallach, David -- Dobbelaere, Dirk A E -- GM63692/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2002 Nov 1;298(5595):1033-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Molecular Pathology, Institute of Animal Pathology, University of Bern, CH-3012 Bern, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12411708" target="_blank"〉PubMed〈/a〉

    Description: Lancelets ('amphioxus') are the modern survivors of an ancient chordate lineage, with a fossil record dating back to the Cambrian period. Here we describe the structure and gene content of the highly polymorphic approximately 520-megabase genome of the Florida lancelet Branchiostoma floridae, and analyse it in the context of chordate evolution. Whole-genome comparisons illuminate the murky relationships among the three chordate groups (tunicates, lancelets and vertebrates), and allow not only reconstruction of the gene complement of the last common chordate ancestor but also partial reconstruction of its genomic organization, as well as a description of two genome-wide duplications and subsequent reorganizations in the vertebrate lineage. These genome-scale events shaped the vertebrate genome and provided additional genetic variation for exploitation during vertebrate evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Putnam, Nicholas H -- Butts, Thomas -- Ferrier, David E K -- Furlong, Rebecca F -- Hellsten, Uffe -- Kawashima, Takeshi -- Robinson-Rechavi, Marc -- Shoguchi, Eiichi -- Terry, Astrid -- Yu, Jr-Kai -- Benito-Gutierrez, E Lia -- Dubchak, Inna -- Garcia-Fernandez, Jordi -- Gibson-Brown, Jeremy J -- Grigoriev, Igor V -- Horton, Amy C -- de Jong, Pieter J -- Jurka, Jerzy -- Kapitonov, Vladimir V -- Kohara, Yuji -- Kuroki, Yoko -- Lindquist, Erika -- Lucas, Susan -- Osoegawa, Kazutoyo -- Pennacchio, Len A -- Salamov, Asaf A -- Satou, Yutaka -- Sauka-Spengler, Tatjana -- Schmutz, Jeremy -- Shin-I, Tadasu -- Toyoda, Atsushi -- Bronner-Fraser, Marianne -- Fujiyama, Asao -- Holland, Linda Z -- Holland, Peter W H -- Satoh, Nori -- Rokhsar, Daniel S -- BBS/B/12067/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBS/B/12067/2/Biotechnology and Biological Sciences Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2008 Jun 19;453(7198):1064-71. doi: 10.1038/nature06967.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Energy Joint Genome Institute, Walnut Creek, California 94598, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18563158" target="_blank"〉PubMed〈/a〉

    Description: The E2F family is conserved from Caenorhabditis elegans to mammals, with some family members having transcription activation functions and others having repressor functions. Whereas C. elegans and Drosophila melanogaster have a single E2F activator protein and repressor protein, mammals have at least three activator and five repressor proteins. Why such genetic complexity evolved in mammals is not known. To begin to evaluate this genetic complexity, we targeted the inactivation of the entire subset of activators, E2f1, E2f2, E2f3a and E2f3b, singly or in combination in mice. We demonstrate that E2f3a is sufficient to support mouse embryonic and postnatal development. Remarkably, expression of E2f3b or E2f1 from the E2f3a locus (E2f3a(3bki) or E2f3a(1ki), respectively) suppressed all the postnatal phenotypes associated with the inactivation of E2f3a. We conclude that there is significant functional redundancy among activators and that the specific requirement for E2f3a during postnatal development is dictated by regulatory sequences governing its selective spatiotemporal expression and not by its intrinsic protein functions. These findings provide a molecular basis for the observed specificity among E2F activators during development.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4288824/" 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/PMC4288824/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsai, Shih-Yin -- Opavsky, Rene -- Sharma, Nidhi -- Wu, Lizhao -- Naidu, Shan -- Nolan, Eric -- Feria-Arias, Enrique -- Timmers, Cynthia -- Opavska, Jana -- de Bruin, Alain -- Chong, Jean-Leon -- Trikha, Prashant -- Fernandez, Soledad A -- Stromberg, Paul -- Rosol, Thomas J -- Leone, Gustavo -- K01CA102328/CA/NCI NIH HHS/ -- P01CA097189/CA/NCI NIH HHS/ -- R01 CA121275/CA/NCI NIH HHS/ -- R01 CA121275-03/CA/NCI NIH HHS/ -- R01CA121275/CA/NCI NIH HHS/ -- R01CA85619/CA/NCI NIH HHS/ -- R01HD042619/HD/NICHD NIH HHS/ -- R01HD047470/HD/NICHD NIH HHS/ -- T32CA106196/CA/NCI NIH HHS/ -- England -- Nature. 2008 Aug 28;454(7208):1137-41. doi: 10.1038/nature07066.

    Description: The human malaria parasite Plasmodium vivax is responsible for 25-40% of the approximately 515 million annual cases of malaria worldwide. Although seldom fatal, the parasite elicits severe and incapacitating clinical symptoms and often causes relapses months after a primary infection has cleared. Despite its importance as a major human pathogen, P. vivax is little studied because it cannot be propagated continuously in the laboratory except in non-human primates. We sequenced the genome of P. vivax to shed light on its distinctive biological features, and as a means to drive development of new drugs and vaccines. Here we describe the synteny and isochore structure of P. vivax chromosomes, and show that the parasite resembles other malaria parasites in gene content and metabolic potential, but possesses novel gene families and potential alternative invasion pathways not recognized previously. Completion of the P. vivax genome provides the scientific community with a valuable resource that can be used to advance investigation into this neglected species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2651158/" 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/PMC2651158/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carlton, Jane M -- Adams, John H -- Silva, Joana C -- Bidwell, Shelby L -- Lorenzi, Hernan -- Caler, Elisabet -- Crabtree, Jonathan -- Angiuoli, Samuel V -- Merino, Emilio F -- Amedeo, Paolo -- Cheng, Qin -- Coulson, Richard M R -- Crabb, Brendan S -- Del Portillo, Hernando A -- Essien, Kobby -- Feldblyum, Tamara V -- Fernandez-Becerra, Carmen -- Gilson, Paul R -- Gueye, Amy H -- Guo, Xiang -- Kang'a, Simon -- Kooij, Taco W A -- Korsinczky, Michael -- Meyer, Esmeralda V-S -- Nene, Vish -- Paulsen, Ian -- White, Owen -- Ralph, Stuart A -- Ren, Qinghu -- Sargeant, Tobias J -- Salzberg, Steven L -- Stoeckert, Christian J -- Sullivan, Steven A -- Yamamoto, Marcio M -- Hoffman, Stephen L -- Wortman, Jennifer R -- Gardner, Malcolm J -- Galinski, Mary R -- Barnwell, John W -- Fraser-Liggett, Claire M -- N01 AI030071/AI/NIAID NIH HHS/ -- R01 AI064478/AI/NIAID NIH HHS/ -- R01 AI064478-05/AI/NIAID NIH HHS/ -- R01 GM070793/GM/NIGMS NIH HHS/ -- R01 GM070793-01A2/GM/NIGMS NIH HHS/ -- R01 GM083873/GM/NIGMS NIH HHS/ -- R01 LM006845/LM/NLM NIH HHS/ -- R01 LM006845-09/LM/NLM NIH HHS/ -- England -- Nature. 2008 Oct 9;455(7214):757-63. doi: 10.1038/nature07327.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Institute for Genomic Research/J.

    Description: The tumour stroma is believed to contribute to some of the most malignant characteristics of epithelial tumours. However, signalling between stromal and tumour cells is complex and remains poorly understood. Here we show that the genetic inactivation of Pten in stromal fibroblasts of mouse mammary glands accelerated the initiation, progression and malignant transformation of mammary epithelial tumours. This was associated with the massive remodelling of the extracellular matrix (ECM), innate immune cell infiltration and increased angiogenesis. Loss of Pten in stromal fibroblasts led to increased expression, phosphorylation (T72) and recruitment of Ets2 to target promoters known to be involved in these processes. Remarkably, Ets2 inactivation in Pten stroma-deleted tumours ameliorated disruption of the tumour microenvironment and was sufficient to decrease tumour growth and progression. Global gene expression profiling of mammary stromal cells identified a Pten-specific signature that was highly represented in the tumour stroma of patients with breast cancer. These findings identify the Pten-Ets2 axis as a critical stroma-specific signalling pathway that suppresses mammary epithelial tumours.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2767301/" 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/PMC2767301/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Trimboli, Anthony J -- Cantemir-Stone, Carmen Z -- Li, Fu -- Wallace, Julie A -- Merchant, Anand -- Creasap, Nicholas -- Thompson, John C -- Caserta, Enrico -- Wang, Hui -- Chong, Jean-Leon -- Naidu, Shan -- Wei, Guo -- Sharma, Sudarshana M -- Stephens, Julie A -- Fernandez, Soledad A -- Gurcan, Metin N -- Weinstein, Michael B -- Barsky, Sanford H -- Yee, Lisa -- Rosol, Thomas J -- Stromberg, Paul C -- Robinson, Michael L -- Pepin, Francois -- Hallett, Michael -- Park, Morag -- Ostrowski, Michael C -- Leone, Gustavo -- P01 CA097189/CA/NCI NIH HHS/ -- P01 CA097189-050002/CA/NCI NIH HHS/ -- P01CA097189/CA/NCI NIH HHS/ -- R01 CA053271/CA/NCI NIH HHS/ -- R01 CA085619/CA/NCI NIH HHS/ -- R01 CA085619-05/CA/NCI NIH HHS/ -- R01 CA121275/CA/NCI NIH HHS/ -- R01 CA121275-02/CA/NCI NIH HHS/ -- R01 HD047470/HD/NICHD NIH HHS/ -- R01 HD047470-05/HD/NICHD NIH HHS/ -- R01CA053271/CA/NCI NIH HHS/ -- R01CA85619/CA/NCI NIH HHS/ -- R01HD47470/HD/NICHD NIH HHS/ -- England -- Nature. 2009 Oct 22;461(7267):1084-91. doi: 10.1038/nature08486.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Genetics, College of Biological Sciences, The Ohio State University, Columbus, Ohio 43210, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19847259" target="_blank"〉PubMed〈/a〉
