Such filaments are usually composed of the contractile proteins actin and / or myosin , and are thought to play a role in cell motility , and perhaps also change in shape 這種絲通常由伸縮蛋白肌動(dòng)蛋白和(或)肌球蛋白組成,一般而言它們在細(xì)胞運(yùn)動(dòng)中起一定作用,并可能改變自身的形狀。
Our recent work also suggest that simulated microgravity may induce the contractile proteins in the arterial vessles to be changed differentially . therefore , in the second part of the present work the alterations of a - sm - actin and calponin were observed by immunohistochemistry and western blotting . the major findings of the present work are as follows : 1 此外,我們的前期工作還提示,不同部位動(dòng)脈血管平滑肌的收縮蛋白在模擬失重下也可能出現(xiàn)分化性變化,故本工作也用免疫組化及westem印跡分析方法對模擬失重大鼠血管的-平滑肌肌動(dòng)蛋白( - sm - actin )及調(diào)寧蛋白( calponin )表達(dá)變化進(jìn)行了觀察。
