Agrin has been found to be involved in axon extension , but the signaling triggered for this response remains unknown Agrin参与神经突起的生长，但是agrin介导的信号通路并不清楚。

Here we have examined the role of musk and rac on neurite extension and axon guidance induced by agrin 我们研究了agrin在突起生长和导向中的作用以及musk和rac对agrin诱导的突起生长和导向作用。
3.
Agrin inhibits rac activity in developing neurons and expression of dominant negative rac1 abolishes agrin - induced growth cone turning and substantially inhibits neurite extension 我们的实验也表明， agrin抑制发育中神经元rac的活性。 dn - rac1的表达完全阻断了agrin引起的生长锥导向，并抑制突起的生长。

Expression of either dominant negative or antisense musk in cultured xenopus laveis spinal neurons abolishes agrin - induced neurite outgrowth inhibition and converts chemorepulsive growth cone turning induced by a gradient of agrin into chemoattraction Musk突变体（ dm - musk ）或反义musk ( as - musk )的表达，解除了agrin对新生突起生长的抑制，并且把agrin诱导的排斥反应反转为吸引反应； musk介导发育中神经元突起的生长。

At the royal canal bridge , from his hoarding , mr eugene stratton , his blub lips agrin , bade all comers welcome to pembroke township . at haddington road corner two sanded women halted themselves , an umbrella and a bag in which eleven cockles rolled to view with wonder the lord mayor and lady mayoress without his golden chain 在哈丁顿路口，两个浑身是沙子的女人停下脚步，手执雨伞和里面滚动着十一只蛤蜊的提包她们倒要瞧瞧没挂金链条的市长224大人和市长夫人是个啥样。
