Retinoblastoma (Rb) tumor‐suppressor pathway alterations in meningeal hemangiopericytomas: High E2F transcription factor 1 expression and loss of Rb expression
Authors: Martinez Juan‐Carlos , Palomino Julio‐Cesar , Samaniego Rafael , Sepulveda Juan M. , Cabello Ana , Ricoy Jose R. 
Published: May 2008

AbstractBACKGROUND.The authors analyzed the retinoblastoma (Rb) tumor‐suppressor pathway in meningeal hemangiopericytomas (MHPCs).METHODS.Immunohistochemical detection of the Rb pathway proteins (Rb; E2F transcription factor 1 [E2F1]; cyclins D1, D3, and E; cyclin‐dependent kinase 4 [CDK4]; and the CDK4 inhibitor p16/INKa) was followed by double immunofluorescence (DIF) staining and laser‐scanning confocal microscopy (LSCM) in 11 MHPC specimens and from 4 specimens of recurrent disease from 1, 2, and 4 recurrences (total, 18 specimens).RESULTS.All specimens displayed Rb pathway alterations, including low or negative Rb protein expression (17 specimens), high Rb protein expression (1 specimen), and loss of p16/INK4a expression (17 specimens). High levels of positive cell‐cycle regulators were observed for E2F1 (10 specimens), cyclin E (7 specimens), CDK4 (5 specimens), cyclin D3 (1 specimen), and cyclin D1 (1 specimen). DIF and LSCM revealed no or very weak Rb and E2F1 colocalization, indicating that Rb does not act as a growth suppressor. High levels of human mouse double‐minute 2 (HDM2) expression were observed in a previous study of these tumors, and they displayed colocalization with E2F1 and Rb in the current study, which supports the argument that HDM2 activates E2F1 and inactivates Rb.CONCLUSIONS.The current findings demonstrated that loss of Rb and p16/INKa expression and high E2F1 expression indicate impairment of the Rb suppressor pathway. HDM2 colocalization with E2F1 and Rb also indicates that Rb suppressor pathway inactivation and transactivation of DNA synthesis genes may play pathogenic roles in MHPCs. High expression levels of cyclin E, cyclin D1, cyclin D3, and CDK4 were associated with Rb suppressor pathway neutralization. Cancer 2008. © 2008 American Cancer Society.
Straightforward Synthesis of Chiral Silylated Amino Acids through Hydrosilylation
Authors: Marchand Damien , Martinez Jean , Cavelier Florine 
Published: May 2008

AbstractA method using hydrosilylation of unsaturated amino acids was developed and optimised to obtain silylated amino acids. The platinum (Bu4N)2PtCl6 complex was identified as the best catalyst, and the procedure tolerated different unsaturated substrates, silane reagents and protecting groups. Seven silicon‐containing α‐amino acids were prepared in an enantiomerically pure form under mild conditions in good yields with orthogonal protections for versatile use in peptide synthesis.(© Wiley‐VCH Verlag GmbH & Co.

Dialkylzinc‐Mediated Atom Transfer Sequential Radical Addition Cyclization
Authors: Feray Laurence , Bertrand Michèle P. 
Published: May 2008

AbstractAlkylative cycloisomerization of N,N‐diallylpropiolamide into α‐alkylidene‐γ‐lactams was mediated by dialkylzinc reagents in aerobic medium. In the presence of an alkyl iodide, final oxidation by iodine‐atom transfer predominates over reductive zincation. The dialkylzinc‐mediated radical process tolerates the presence of the acidic terminal alkyne. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
Phylogenetic position of Brossardia papyracea (Brassicaceae) based on sequences of nuclear ribosomal DNA
Authors: Reza Khosravi A. , Mohsenzadeh S. , Mummenhoff K. 
Published: May 2008

AbstractIn previous taxonomic literature, the monotypic genus Brossardia Boiss. was suggested to be related to Thlaspi L. s.l. and Aethionema R.Br. ITS sequence data of Brossardia papyracea * were added to a previously published data set, which includes sequences of representative taxa of Aethionema and Thlaspi s.l., to elucidate the systematic position of B. papyracea. Our molecular analysis indicates that B. papyracea is not a member of Aethionema, but is instead, nested within Noccaea Moench, a segregate lineage of the non‐monophyletic Thlaspi s.l. Based on these results and a re‐evaluation of morphological characters, we have transferred B. papyracea to Noccaea: Noccaea papyracea (Boiss.) Khosravi, Mummenhoff & Mohsenzadeh.), comb. nov.

East Greenland freshwater runoff to the Greenland‐Iceland‐Norwegian Seas 1999–2004 and 2071–2100
Authors: Mernild Sebastian H. , Liston Glen E. , Hasholt Bent 
Published: May 2008

AbstractIn this paper, we quantify the terrestrial flux of freshwater runoff from East Greenland to the Greenland‐Iceland‐Norwegian (GIN) Seas for the periods 1999–2004 and 2071–2100. Our analysis includes separate calculations of runoff from the Greenland Ice Sheet (GrIS) and the land strip area between the GrIS and the ocean. This study is based on validation and calibration of SnowModel with in situ data from the only two long‐term permanent automatic meteorological and hydrometric monitoring catchments in East Greenland: the Mittivakkat Glacier catchment (65°N) in SE Greenland, and the Zackenberg Glacier catchment (74°N) in NE Greenland. SnowModel was then used to estimate runoff from all of East Greenland to the ocean. Modelled glacier recession in both catchments for the period 1999–2004 was in accordance with observations, and dominates the annual catchment runoff by 30–90%. Average runoff from Mittivakkat, ∼3·7 × 10−2 km3 y−1, and Zackenberg, ∼21·9 × 10−2 km3 y−1, was dominated by the percentage of catchment glacier cover. Modelled East Greenland freshwater input to the North Atlantic Ocean was ∼440 km3 y−1 (1999–2004), dominated by contributions of ∼40% from the land strip area and ∼60% from the GrIS. East Greenland runoff contributes ∼10% of the total annual freshwater export from the Arctic Ocean to the Greenland Sea. The future (2071–2100) climate impact assessment based on the Intergovernmental Panel on Climate Change (IPCC) A2 and B2 scenarios indicates an increase of mean annual East Greenland air temperature by 2·7 °C from today's values. For 2071–2100, the mean annual freshwater input to the North Atlantic Ocean is modelled to be ∼650 km3 y−1: ∼30% from the land strip area and ∼70% from the GrIS. This is an increase of approximately ∼50% from today's values. The freshwater runoff from the GrIS is more than double from today's values, based largely on increasing air temperature rather than from changes in net precipitation.

Mitochondrial copper metabolism and delivery to cytochrome c oxidase
Authors: Horn Darryl , Barrientos Antoni 
Published: May 2008

AbstractMetals are essential elements of all living organisms. Among them, copper is required for a multiplicity of functions including mitochondrial oxidative phosphorylation and protection against oxidative stress. Here we will focus on describing the pathways involved in the delivery of copper to cytochrome c oxidase (COX), a mitochondrial metalloenzyme acting as the terminal enzyme of the mitochondrial respiratory chain. The catalytic core of COX is formed by three mitochondrially‐encoded subunits and contains three copper atoms. Two copper atoms bound to subunit 2 constitute the CuA site, the primary acceptor of electrons from ferrocytochrome c. The third copper, CuB, is associated with the high‐spin heme a3 group of subunit 1. Recent studies, mostly performed in the yeast Saccharomyces cerevisiae, have provided new clues about 1) the source of the copper used for COX metallation; 2) the roles of Sco1p and Cox11p, the proteins involved in the direct delivery of copper to the CuA and CuB sites, respectively; 3) the action mechanism of Cox17p, a copper chaperone that provides copper to Sco1p and Cox11p; 4) the existence of at least four Cox17p homologues carrying a similar twin CX9C domain suggestive of metal binding, Cox19p, Cox23p, Pet191p and Cmc1p, that could be part of the same pathway; and 5) the presence of a disulfide relay system in the intermembrane space of mitochondria that mediates import of proteins with conserved cysteines motifs such as the CX9C characteristic of Cox17p and its homologues. The different pathways are reviewed and discussed in the context of both mitochondrial COX assembly and copper homeostasis. © 2008 IUBMB IUBMB Life, 60(7): 421–429, 2008
