BDNF promoted Etv4 and Etv5 and their mRNA expression in DRG neurons.
Inhibition of ERK1/2 blocked the effects of BDNF on Etv4 and Etv5 expression.
siRNA of Etv4 and Etv5 blocked BNDF induced VGLUT3 expression and neurite growth.
Overexpression of Etv4 or Etv5 potentiated BNDF induced neurite elongation.
Etv4 or Etv5 is essential transcription factor for BDNF mediating VGLUT3 expression.
