在本报告中,我们研究了异黄酮染料木素是否能促进神经生长因子(NGF)诱导的PC12细胞的神经突生长。染料木素对神经生长因子诱导的神经突生长有促进作用。Na+/K+/2Cl-共转运蛋白异构体1 (NKCC1)的下调可消除染料木素对神经突生长的刺激作用。这些观察结果表明,尽管染料木素对NKCC1的蛋白表达没有影响,但NKCC1对于染料木素刺激ngf诱导的神经突生长至关重要。另一方面,染料木素可以激活NKCC1,这在我们之前的研究中得到了证实。综上所述,这些观察结果表明染料木素通过激活NKCC1增强了ngf诱导的PC12细胞的神经突生长。
In the present report, we studied if an isoflavone, genistein, enhances the nerve growth factor (NGF)-induced neurite outgrowth of PC12 cells. Application of genistein enhanced the NGF-induced neurite outgrowth. Knockdown of Na+/K+/2Cl- cotransporter isoform 1 (NKCC1) abolished the stimulatory effect of genistein on the neurite outgrowth. These observations indicate that NKCC1 is essential for genistein to stimulate the NGF-induced neurite outgrowth, although genistein had no effect on the protein expression of NKCC1. On the other hand, genistein activates NKCC1 as shown in our previous study. Taken together, these observations indicate that genistein enhanced the NGF-induced neurite outgrowth in PC12 cells via activation of NKCC1.
