肌动蛋白

During contraction, these filaments slide past one another, thereby shortening the length of the sarcomere.

由于肌球蛋白和肌动蛋白的作用，粗丝和细丝相对滑动引起肌肉的收缩。

The purpose of this study was to investigate the effects of downhill running once and for one week on α-actin gene expression of rat gastrocnemius muscle.

本研究观察1次和1周下坡跑训练对大鼠腓肠肌肌动蛋白基因表达的影响及血清CK、LDH的变化。

The motor molecule forms bipolar thick filaments that interdigitate with thinner actin filaments in the saromere, forming the basic contractile unit of muscle.

由于肌球蛋白和肌动蛋白的作用，粗丝和细丝相对滑动引起肌肉的收缩。

Results Actin was only detected in myoepithelial cells of normal breast tissue and grade Ⅰ and Ⅱ atypical hyperplasia.

结果 正常乳腺组织和Ⅰ级一般性增生乳腺组织中肌动蛋白只在肌上皮细胞中表达。

The changes of actin expression in atypical hyperplasia are possibly correlated with carcinogenesis of breast cancer, and myoepithelial cells may play a role in carcinogenesis of breast cancer.

乳腺不典型增生时肌动蛋白表达的变化可能与乳腺癌的发生有关，肌上皮细胞可能参与了乳腺癌的发生。

Methods SP immunohistochemistry was used to detect actin expression in normal breast tissue, grade Ⅰ,Ⅱ and Ⅲ atypical hyperplasia and breast cancer. Electromicroscopy was used to observe the changes of ultrastructure of myoepithelial cells.

用免疫组化SP法分别检测正常乳腺组织、Ⅰ级一般性增生和Ⅱ级、Ⅲ级不典型增生乳腺组织及乳腺癌组织中肌动蛋白的表达情况，并用电镜观察肌上皮细胞超微结构的变化。

The purpose of this study was to examine the cellular surface blebs of oxidative damage. The important is cytoskeletal proteins-actin and tubulin acts in cellular surface blebs.

本实验主要目的在探讨氧化伤害与小泡生成的关系，尤其著重在细胞架构蛋白-肌动蛋白与管蛋白两者在小泡生成时扮演的角色。

Incubated with cytochalisin B for 4 hours, F-actin bunddles disrupted, confluent ECs monolayer has a complete detachment from the coverslips. So, there is a suggestion that the F-actin in ECs is essential for endothelial adherence under shear stress.

Northcrn杂交结果表明外源性纤维连接蛋白有促进EC肌动蛋白表达的作用，结合F-actin染色及FN受体染色结果，本文认为用纤维连接蛋白作为细胞种植的促粘附物质有助于内皮细胞粘附结构的形成。

Recent studies showed that Rho GTPase played a key role in the reorganization of cytoskeleton and in Swiss 3T3 cells, Cdc42, Rac1 and RhoA, three members of Rho superfamily of small GTPase, regulated the polymerization of actin to produce filopodia , lamellipodia, stress fiber and focal adhension, respectively.

近年来的研究表明，Rho家族小G蛋白是细胞骨架肌动蛋白的重要调节因子，目前众多的研究集中在Rho小G蛋白家族成员中的Cdc42、Rac1和RhoA，其中Cdc42促进丝状伪足的形成，Rac1调节板装伪足的生成和膜皱缩，RhoA则促进粘着斑连接和张力纤维的装配。

Actin filaments can form long and thin bundles in the filopodia, and can also exist as the actin meshwork in the lamelipodia.

肌球蛋白通常与肌动蛋白结合成束形成张力纤维丝。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
