摘要:

我们提出了一个随机模型,占的增长,灾难和救援过程的稳态微管组装从MAP自由微管蛋白。实验和理论上,我们研究了微管动态不稳定性的扰动由S-甲基-D-DM1,一种合成的衍生物的微管靶向剂美登素和一种潜在的抗癌剂。我们发现,作为一种有效的抑制剂的微管动力学的药物必须主要抑制损失的GDP微管蛋白从微管尖端。

英文摘要:

We propose a stochastic model that accounts for the growth, catastrophe and rescue processes of steady state microtubules assembled from MAP-free tubulin. Both experimentally and theoretically we study the perturbation of microtubule dynamic instability by S-methyl-D-DM1, a synthetic derivative of the microtubule-targeted agent maytansine and a potential anticancer agent. We find that to be an effective suppressor of microtubule dynamics a drug must primarily suppress the loss of GDP tubulin from the microtubule tip.
