Prickle promotes neurite outgrowth via the Dishevelled dependent pathway in C1300 cells.
Murine Prickle1 and Prickle2 belong to the planar cell polarity genes. Prickle2 but not Prickle1 gene expression was induced in C1300 neuroblastoma cells during neurite-like process formation induced by retinoic acid (RA). Over-expression of Prickle1 or Prickle2 in C1300 cells induced striking neurite-like process formation in the absence of RA. ... Since Prickle binds to Dishevelled (Dvl) to induce its degradation in Drosophila, we examined the participation of Dvl protein in the neurite-like process formation of C1300 cells. Upon induction of the neurite-like process formation, the amount of Dvl1 protein decreased. Prickle1 and Prickle2 could associate with Dvl1 and over-expression of Prickle1 or Prickle2 resulted in the reduction of Dvl1 protein in C1300 cells. Furthermore, over-expression of Dvl1 in C1300 cells prevented the neurite-like process formation induced by Prickle1 or Prickle2 over-expression. Thus, Prickle1 and Prickle2 promote neurite-like process formation of C1300 cells via the Dvl1 dependent mechanism.
