    • The finding that Dickkopf1 (Dkk1) is a dual function protein demonstrates a mechanism for the coordination of cell migration and antagonism of Wnt/β-catenin signaling during developmental and pathological processes. The profile of Dkk proteins expressed by human breast cancers correlates with indicators of outcome: Dkk1 associates with markers of poor prognosis whereas expression of single function Dkk2 or Dkk3 (which inhibit Wnt/β-catenin signaling and promote migration, respectively) correlates with phenotypes reflective of good prognosis. Therefore, the pro-migratory activities of Dkk1 and 3 identified here offer new insights into breast cancer progression and a potential avenue for therapeutic intervention.
    • Dickkopf1(Dkk1)是双功能蛋白的发现证明了在发育和病理过程中协调细胞迁移和Wnt /β-连环蛋白信号的拮抗作用的机制。 由人类乳腺癌表达的Dkk蛋白的特征与结果指标相关:Dkk1与预后不良的标志物相关,而单功能Dkk2或Dkk3(分别抑制Wnt /β-连环蛋白信号传导和促进迁移)的表达与反映的表型相关 预后良好。 因此,这里鉴定的Dkk1和3的亲迁移活动为乳腺癌进展提供了新的见解,也是治疗干预的潜在途径。
