肌动蛋白

Whereas, in unactivated mouse spleen T lymthocytes, no binding could be found. Actin was closely associated to BAF complex and RNA Polymerase Ⅱ, but not so closely to NF1/CTF.

In this study we provide evidence that inhibition of Rho kinase activation or myosin contractility abrogates PMA-induced apoptosis, and turns cells to undergo PMA-induced differentiation program, suggesting a switching role for the RhoAJROCK/myosin contraction pathway in cell fate decision.

A The slimmest single filament is most similar to F-actin in size with ～7 nm width at half height and ～35 nmpitch ; the filaments have much wider diameter than the slimmest F-actin ; The branch filament could be con-stituted of two enlaced slimmer filaments , forming the branch in the joining point of another filament ; Two fila-ments are aligned side by side , and thought that there might exist certain interaction between them , which could be theearly step for further assembly of giant filaments.

肌动蛋白可通过自组织过程聚合形成不同直径(7nm～35nm)的长纤维，实验中观察到的最细纤维的结构参数与单根无鬼笔环肽结合时的F-actin[19 ]一致(Fig。 2 a)；此外，还有大量具有较大直径和分支结构的纤维出现，表明有不同于单根微丝和微丝束的高级纤维结构产生Fig。

PHBV was implanted subcutaneously in rabbit and extirpated at 2,4,6,8, and 10 weeks in order to study its biocompatibility and biodegradability.

The full-length genome cDNA containing genetic tags and flanked by Hammerhead ribozyme and Hepatitis delta ribozyme were cloned downstream of the CMV enhancer and the chicken beta actin promoter of the vector pCAGGS. After purified by Plasmid Midi Kit, the recombinant infectious clones named pCAGGmGtAHRT and pCAGGmGtBHRT were directly co-transfected DFI cells indued by Lipofectamine~ 2000. 72h post transfection. the supernatant of cell cuture was harvested and continue passaged in CEF cell. The results of indirect immunofluorescence.

分别在Gt株基因组两端引入了锤头状核酶结构(Hammerhead ribozyme，HamRz)和丁肝病毒核酶结构(Hepatitis delta ribozyme，HdvRz)，并将其克隆在真核表达载体pCAGGS的CMV增强子和β肌动蛋白启动子下游，构建IBDV感染性克隆pCAGGmGtAHRT和pCAGGmGtBHRT，经Plasmid Midi Kit纯化后，在Lipofectamine~ 2000的介导下，直接转染DFI细胞，72h后取上清继续在CEF上传代。

On the sixtieth postoperative day, the graft was harvested and the blood was taken from inferior cava venae. Histological changes were monitored by HE stain. The infiltration of CD4+ and CD8+ T lymphocytes and the expression ofα- smooth muscle actin were detected by immunohistochemistry.

术后60天取移植血管做病理组织学检查并利用计算机图象分析系统测量血管内膜厚度；免疫组织化学检测CD4+、CD8+T淋巴细胞的浸润及α-平滑肌肌动蛋白的表达；ELISA法检测血清中血管内皮生长因子的变化。
