趋化运动是一个基本的生命现象。单细胞的趋化运动能力在细菌觅食,粘菌发育,线虫的神经发育,以及人体的发育和免疫应答中起着关键的作用。癌细胞的迁移和扩散同样受到趋化运动的调控。我们课题组的工作重点是解析癌细胞趋化运动的分子机理,并以此为基础,寻找抗癌扩散的信号分子靶点,筛选新型抗癌扩散药物。 近期代表性文章 Wan W, Zou H, Sun R, Liu Y, Wang J, Ma D, Zhang N. “Investigate the role of PTEN in chemotaxis of human breast cancer cells.” Cell Signal. 2007 Jun 23; [Epub ahead of print] Caijie Zhao, Mi Cai, Yao Zhang, Ying Liu, Ronghua Sun, and Zhang N “Development of a microscopy-based assay for PKC activation in human breast cancer cells” Analytical Biochemistry 2007 Mar 1;362(1):8-15.
