近年来的研究发现,Wnt-β-catellin信号通路与肿瘤侵袭转移的相关事件如癌细胞的迁移粘附、细胞外基质的降解及肿瘤的血管生成密切相关。Wnt信号还能激活Wnt—Ca2^ 、Wnt—JNK等非正规通路,与人类肿瘤的侵袭转移也有一定关系。另外,Wnt通路还可通过与细胞内其他信号通路如K—ras、RTK及ILK介导的信号通路相互作用,在肿瘤侵袭转移过程中起重要作用。 相似文献

Wnt single transduction pathway plays a key role in fetal development and central nervous system formation, and regulates cell growth,migration and differentiation. It mainly consist of the classical Wnt βcatenin pathway and the non classical pathway. Recent researches reveal that the Wnt pathway is associated with cancer, and its important role in lung cancer genesis and development has been revealed gradually. 相似文献

Wnt signaling pathway plays an important role in physiological and pathological process, including in the occurrence and development of tumor. The purpose of this study is to determine whether Wnt2 and sFRP4, key molecules of signaling pathway, are of prognostic value for survival in patients with pancreatic cancer. We performed immunohistochemistry on tissue microarrays containing 90 pancreatic cancer specimens to evaluate the protein expression of Wnt2 and sFRP4. Our results showed that the cytoplasmic expression level of Wnt2 in pancreatic cancer tissues was significantly associated with LNM (P=0.029) and AJCC stage (P=0.008). Additionally, Kaplan-Meier analysis indicated that high Wnt2 expression was significantly correlated with poor clinical outcomes of patients with pancreatic cancer. In conclusion, Wnt2 may play an important role in the development of pancreatic cancer through activation of the Wnt pathways and serve as a potential candidate for treatment target of pancreatic cancer. 相似文献
