Research Abstract

DKK1 suppress nuclear accumulation ofβ-catenin induced by Wnt3a in serum starved Ewing's sarcoma cells and it is suggested that the DKK1 inhibit classical WNT signal in these cells. Although DKK1 suppress tumor formation in xenotranplatation model of Ewing's sarcoma, DKK1 added in the standard cell culture environment seems not to affect tumor formation nor proliferation. Tumor formation might be suppressed in vivo via mechanisms, like suppression of angiogenesis.
