Periostin在肿瘤中的作用

Roles of periostin in cancer

Periostin在多种肿瘤组织中特异性表达,与肿瘤的进展及预后相关,通过抑制肿瘤细胞的凋亡,促进肿瘤生长.近年的研究表明,其诱导血管形成的机制是通过αvβ3-FAK和Flk-1/KDR等多种信号转导途径来实现.且其参与上皮-间质转变过程进而促进肿瘤侵袭和转移.Periostin有可能作为一种潜在的治疗靶点用于临床.

Periostin, a extracellular matrix protein structurally similar to fasciclin proteins, is expressed specifically in various tumor tissues and correlates with tumor progression and prognosis. Periostin prevents the apoptosis of tumor cells, promotes tumor growth and can induce angiogenic signaling cascades through αvβ3-FAK and Flk-1/KDR. It also contributes to epithelial-mesenchymal-transformation promoting tumor invasion and metastasis. Periostin maybe a potential therapeutic target of cancer treatment.
