体外研究 | BlebbistatinYZ细胞分裂,改变鱼角膜细胞的平滑运动,且YZ缺乏细丝蛋白的细胞系进行自发起泡。BlebbistatinYZ非肌肉肌球蛋白IIA,非肌肉肌球蛋白IIB,和兔骨骼肌肌球蛋白S1的HMM片段的酶活性,而不YZ平滑肌球蛋白。[1]Blebbistatin快速且可逆YZMg-ATPase活性,也YZ非肌肉肌球蛋白IIA和IIB的体外活性,而极其微弱YZ平滑肌肌球蛋白(IC50=80 μM)。Blebbistatin有效YZDictyosium肌球蛋白II,但极其微弱YZAcanthamoeba肌球蛋白II。Blebbistatin不YZ代表性的I,V,和X型肌球蛋白超家族成员。[2]Blebbistatin不与核苷酸竞争性结合到骨骼肌肌球蛋白亚片段-1。Blebbistatin优先结合到ATP酶,与ADP和磷酸盐在活性位点相互作用,减慢磷释放。Blebbistatin既不干扰肌球蛋白与肌动蛋白结合,也不干扰ATP诱导的肌动球蛋白解离。[3] |

推荐的实验操作
(此推荐来自于公开的文献所以Selleck并不保证其有效性)激酶实验:[2]
肌动蛋白活化的MgATPase检测 | 通过NADH耦合检测,使用Beckman DU 640分光光度计测量肌动蛋白活化的MgATPase活性。Blebbistatin[(+)和(-)对映体的外消旋混合物]溶解在DMSO中, 所有样品中DMSO浓度维持在恒定浓度5%。 |

(C) MyoIIA inhibition by blebbistatin treatment in vivo impairs leukemia cell extravasation into the brain. One hour before B-ALL cell transfer, C57BL/6 CD45.1+ recipient mice were treated with vehicle or blebbistatin (2.5 mg/kg). Twenty-four hours after B-ALL cell transfer, the recipient mice were intravenously injected with CD19-APC antibodies and then euthanized 4 min later.

b Densitometric quantification and representative immunoblot of TCL and CM from RASMC preincubated with blebbistatin (1.25-10 μmol/l) for 1 h before exposure to 20 μg/ml ox-LDL for 24 h. Results are presented as mean ± SEM of 3 independent experiments performed in triplicate. * p < 0.05 compared with ox-LDL alone.
