简介
Objectives
We previously showed that ΔNp63β, a splicing variant of ΔNp63, mediated EMT and affected cell motility. DNA microarray was thus performed to elucidate the mechanism that ΔNp63β affects cell motility. As the results, Wnt5a was significantly down-regulated by ΔNp63β overexpression in tongue SCC cell line (SQUU-B) with EMT phenotype.
Materials and methods
Seven OSCC cell lines were used. Expression of ΔNp63, Wnt5a, its receptor Ror2, and matrix metalloproteinases (MMPs) were analyzed by RT-PCR, real-time PCR, and western blotting, and gelatin zymography. Furthermore, we examined the effects of siRNA for Wnt5a or Ror2 and recombinant human Wnt5a (rhWnt5a) on motility of tongue SCC cells. Biopsy specimens from tongue SCC patients were used for immunohistochemical staining of Wnt5a and Ror2.
Results
Wnt5a and Ror2 were expressed only in SQUU-B cells without ΔNp63 …
