目的:采用蛋白质的方法进行向心肌细胞的直接转分化,不但避免了病毒带来的毒副作用,而且大大提高了转分化的效率.方法:采用原核生物表达系统获得重组的心肌转录因子GATA4、HAND2、MEF2C和TBX5 (GHMT),利用QQ-modify技术将这些蛋白高效转导到人皮肤成纤维细胞株(HDF),检测它们的转导效率,并探讨HDF向心脏细胞的转分化效果.

目的:Rho相关激酶(ROCK)的活化在压力超负荷介导的左心室重构中发挥重要作用,然而其潜在的病理分子机制不是十分明确.在前期研究中,我们发现TGF-β1通过诱导ROCK活化和抑制内源性BMP-2水平,加重了心肌纤维化的程度;因此,我们试图通过外源性补充BMP-2分子观察是否可有效改善压力超负荷激活TGF-β1引起的心肌纤维化,并阐明内在的病理机制.
