3Downregulation of the Spi-1/PU.1 oncogene induces the expression of TRIM10/HERF1, a key factor required for terminal erythroid cell differentiation and survival显示文摘Spi-1/PU.1 和 Fli-1 oncoproteins 的持续表示在老鼠 erythroleukemia 房间堵住 globin 基因激活;然而,仅仅 Spi-1/PU.1 表示禁止 exon 的包括 16 在成熟 4.1R mRNA。这个拼接的事件为红血房间膜正直为功能的 4.1R 蛋白质并且,因此是关键的。这份报告证明 Spi-1/PU.1 downregulation 导致 TRIM10/hematopoietic 戒指手指 1 的激活(HERF1 ) ,分成三部分的主题(修剪) 的一个成员为 globin 基因抄写需要的 /RBCC 蛋白质家庭。另外,我们证明 TRIM10/HERF1 为 exon 拼接调整被要求 16 在迟了的 erythroid 区别期间。用可诱导的 overexpression 和 silencing 途径,我们发现了那:(1 ) TRIM10/HERF1 击倒在导致的 dimethylsulfoxide (DMSO ) 禁止拼接的血红素生产和 exon 和扳机房间 apoptosis 房间;(2 ) TRIM10/HERF1 upregulation 被要求,但是在它的自己上是不够的激活 exon 保留;(3 ) Fli-1 没在 TRIM10/HERF1 表示上有效果,而也导致 DMSO 的 downregulation 或 Spi-1/PU.1 shRNA 击倒表示是足够的激活 TRIM10/HERF1 表示;并且(4 ) Spi-1/PU.1 击倒的扳机抄写和拼接的事件独立于化学正式就职。总的来说,这些数据显示主要 Spi-1/PU.1 downregulation 通过至少二条小径,其一条要求 TRIM10/HERF1 upregulation 和平行对迟了的 erythroid 区别起作用 Spi-1/PU.1-induced Fli-1 用以遮闭之物规章的串联。Rand Blaybel Orianne Theoleyre Alexandre Douablin Faouzi Baklouti 2008Cell Research2008,18,8:3
4血小板功能测定显示文摘1 简介 血小板在止血和血栓中的作用 当血管损伤时,血小板会迅速粘附到损伤处,聚集形成由纤维蛋白固定的止血块.在微血管损伤处及破裂的动脉粥样硬化斑块处也会发生类似的过程,最终形成血小板-纤维蛋白血栓,引发动脉硬化症的血栓性并发症.Rand ML Leung R Packham MA 金蕾 2004国外医学(输血及血液学分册)2004,27,4:3

7Hollow-core antiresonant terahertz fiber-based TOPAS extruded from a 3D printer using a metal 3D printed nozzle显示文摘We report the use of a terahertz(THz)transparent material,cyclic olefin copolymer(COC or TOPAS),for fabricating a hollow-core antiresonant fiber that provides an electromagnetic wave guidance in the THz regime.A novel fabrication technique to realize a hollow-core antiresonant polymer optical fiber(HC-ARPF)for THz guidance is proposed and demonstrated.The fiber is directly extruded in a single-step procedure using a conventional fused deposition modeling 3 D printer.The fiber geometry is defined by a structured nozzle manufactured with a metal 3 D printer,which allows tailoring of the nozzle design to the various geometries of microstructured optical fibers.The possibility to use the HC-ARPF made from TOPAS for guiding in the THz region is theoretically and experimentally assessed through the profile of mode simulation and time-frequency diagram(spectrogram)analysis.WANVISA TALATAISONG JON GORECKI LIEKE D.VAN PUTTEN RAND ISMAEEL JAMES WILLIAMSON KATIE ADDINALL DANIEL SCHWENDEMANN MARTYNAS BERESNA VASILIS APOSTOLOPOULOS GILBERTO BRAMBILLA 2021Photonics Research2021,9,8:2
8Role of gap junctions in endothelium-derived hyperpolarizing factor-mediated vasodilatation in rat renal artery显示文摘AIM: To investigate the effects of gap junction inhibitors on endothelium-derived but nitric oxide (NO)- and prostacyclin (PGI2)-independent vasodilatations induced by carbachol in the rat isolated renal artery. METHODS: Isolated renal arteries were mounted on a wire myograph apparatus were tissues treated with the nitric oxide synthase inhibitor N^ω-nitro-L-arginine methyl ester hydrochloride (NAME; 100 μmol/L) and indomethacin (10 μmol/L) and precontracted with phenylephrine (0.1 μmol/L). NAME and indomethacin treated Carbachol (0.01-10 μmol/L)- or sodium nitroprusside (SNP; 1-300 nmol/L)-induced mediated relaxations were observed in the presence of gap junction inhibitors. RESULTS: Carbachol produced a concentration-dependent relaxation in tissues treated with NAME (100 μmol/L) and indomethacin (10 μmol/L). This relaxation was not affected by hemoglobin (3 μmol/L), but was inhibited by charybdotoxin (200 nmol/L) and ouabain (30 μmol/L). The putative gap junction inhibitors, GAP 27 peptides with sequence homology to connexins 40 and 43 respectively reduced carbachol- but not SNP-induced relaxations mediated by endothelium-derived hyperpolarizing factor (EDHF)-mediated relaxations. The inhibition by the connexin 43 inhibitor was greater than that of the connexin 40 inhibitor. CONCLUSION: The results indicate the presence of gap junctions sensitive to 43^GAP 27 and 43^GAP 27 in the rat renal artery and each of these different types of gap junctions plays a role in the NO- and PGI2-independent relaxations induced by carbachol in this blood vessel. However, connexin 43 appears to play a more predominant role in mediating gap junction communications in the rat renal artery.Joanna KARAGIANNIS Michael RAND 2004Acta Pharmacologica Sinica2004,25,8:2
