IFN-type-I-mediated signaling is regulated by modulation of STAT2 nuclear export
Authors: Frahm Thomas , Hauser Hansjörg , Köster Mario 
Published: March 2006

Signaling through the IFN type I receptor is mediated by assembly of the ISGF3 complex consisting of STAT1, STAT2 and IRF9. Whereas STAT1 is instrumentalized by many cytokines, STAT2 is specifically used by type I IFNs. Here, we report that the main regulatory mechanism of nuclear accumulation of STAT2 is nuclear export. We determined the kinetics of nucleocytoplasmic shuttling of STAT2 in living cells. In the absence of IFN, a virtually exclusive cytoplasmic localisation of STAT2 can be detected. Nevertheless, STAT2 is permanently and rapidly shuttling between the cytoplasm and the nucleus. The steady-state localization is explained by a very efficient nuclear export. Our studies indicate that at least two pathways (one of which is CRM1-dependent, the other not yet identified) are responsible for clearing the nucleus from STAT2. The constitutive nucleocytoplasmic shuttling of STAT2 does neither depend on the presence of IRF9 or STAT1, nor does it require tyrosine phosphorylation. Upon treatment with IFN type I, nuclear export of STAT2 is completely abolished in cells used within this study, whereas nuclear import is functioning. This explains the observed nuclear accumulation of STAT2. We have identified a region in the C-terminus of STAT2 that is essential for its almost exclusively cytoplasmic localization in the absence of IFN and responsible for CRM1-specific export.
In comparative studies we show that nucleocytoplasmic shuttling of STAT2 is significantly different from that of STAT1. STAT1 is also shuttling in the absence of IFN, but the exchange rate in unstimulated cells is more than ten times lower. We further show that the latent STAT2 protein has stronger intrinsic nuclear-export activity than STAT1. Together, these observations lead to a model for IFN-type-I-induction in which the receptor-mediated heterodimerization overcomes the slow nuclear import of STAT1 and blocks the strong STAT2 export activity that leads to the accumulation of both signal transducers in the nucleus.

Authors: Sasaki Shigeru , Iyoda Masahiko 
Published: March 2006

Abstract
A series of di-, tri-, tetra-, and pentaamines were synthesized as precursors for corresponding di-, tri-, tetra-, and penta(aminium radical-cations) by the aryl-N bond formation reaction between aryl iodides and in situ prepared copper amide in refluxing pyridine. Cyclic voltammograms of meta-connected derivatives consisted of irreversible waves which imply side reactions in addition to oxidation to aminium radical-cations.

Abstract
By using electropolymerized poly(3-n-octylthiophen) (PAT8) film as a hole transporting layer, the light-emission of an organic electroluminescence layer of poly(N-vinylcarbazole) dip-coating layer doped with 2,5-bis(1-naphthyl)-1,3,4-oxadiazole and 3-(2′-benzothiazolyl)-7-diethylaminocoumarin, was remarkably enhanced as compared with the layer without PAT8 layer. The addition of the hole transporting layer made the turn-on bias reduce and the emission intensity increase to be 600 cd m−2.

Authors: Glück Guiscard , Okumura Yukihisa , Sunamoto Junzo 
Published: March 2006

Abstract
A direct reconstitution method, possibly under non-denaturing conditions, was developed to study membrane protein-lipid monolayer at the air/water interface. Proteins were first transferred from intact human erythrocytes or ghosts to liposomes, which spontaneously transformed at the air/water interface. Then, by using the wet-bridge method, a stable protein containing monolayer by means of surface pressure/area diagrams was formed that exhibited erythrocyte acetylcholinesterase activity.

Abstract
We have succeeded in predicting a molecular crystal structure from first principles. The potential parameters and geometry for CO2 molecule were determined by ab initio molecular orbital calculations. The experimentally observed CO2 crystal structures at low and high pressures have been reproduced by molecular dynamics method without any a priori assumptions on lattice constants nor space group symmetry. With extra pressure of 1 GPa in [010] direction, the structural change observed at about 10 GPa has also been reproduced.

Abstract
Treatment of an overcrowded diarylgermylene bearing 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl and 2,4,6-triisopropylphenyl groups with tribenzylamine N-oxide gave the corresponding diarylgermanone 4, the first example of a stable germanium-oxygen double-bond compound.

Palladium-Catalyzed Cleavage of P-C Bonds in Quaternary Phosphonium Salts and Its Applications to Organic Synthesis
Authors: Sakamoto Masato , Shimizu Isao , Yamamoto Akio 
Published: March 2006

Abstract
Phosphonium salts, PPh4I and PMePh3I, oxdatively add to Pd(methyl acrylate)(PMePh2)2 to give trans-[PdPhI(PMePh2)2] in moderate yields with cleavage of the P-phenyl bond. Conversely thermolysis of trans-PdPhIL2 (L = PMePh2 and PPh3) reductively eliminates PMePh3I and PPh4I, respectively. Application of the P-C bond cleavage process in phosphonium salts to olefination, carbonylation and hydrogenation reactions has been explored.

Thermolysis of β-Siloxyalkylboranes: Formation of Alkenes and/or Silyl Enol Ethers
Authors: Kawashima Takayuki , Yamashita Naoko , Okazaki Renji 
Published: March 2006

Abstract
erythro-Trimethylsilyl ether 3a underwent stereospecific and quantitative syn-elimination of trimethylsiloxy(dimesityl)borane upon heating to give (Z)-β-methylstyrene like the corresponding hydroxy borane 1, whereas the thermolysis of t-butyldimethlsilyl ether 3c afforded mainly (Z)-silyl enol ether 6 by elimination of dimesitylborane. Triethylsilyl ether 3b gave a mixture of both products. These results indicate that two elimination reactions via a four-centered transition state proceed competitively depending on the steric bulkiness of the silyl group.

Published: March 2006

Abstract
Electroreduction of dibromodifluoromethane in the presence of diphenyldiselenide and olefins in a DMF-(Pt)-(Al) system provided adducts of in situ generated bromodifluoromethyl radical and phenylselenenyl group to olefins. One electron transfer from benzeneselenolate to CF2Br2 induces the formation of CF2Br· radical. This system is also useful for generation of ·CF2CO2Et radical from ethyl bromodifluoroacetate.

Abnormal Dielectric Response of Aerosol OT W/O Microemulsion in Cyclohexane at 298.15 K
Authors: Tanaka Reiji , Okazaki Kaori , Tsuzuki Hideo 
Published: March 2006

Abstract
A dielectric constant for W/O microemulsions consisting of sodium bis (2-ethyhexyl) sulfosuccinate (AOT), water and cyclohexane was measured at 1 MHz and at 298.15 K. Minima were found in the dielectric constant when a molar ratio of water to AOT was 15 irrespectively of the AOT concentration. This minimum would be related to symmetric hydration of ions, therefore, water pool in the microemulsion becomes more nonpolar around the ratio of 15.

Abstract
Two sets of new fucoxanthin or zeaxanthin-linked pyropheophorbides were prepared to compare the intramolecular excited-state interactions. Fucoxanthin acts as a better antenna toward pyropheophorbide by transferring singlet energy from its S1-state, while zeaxanthin is a poorer antenna and quenches the S1-state of the pyropheophorbide possibly by reverse energy transfer.
