Cancer metastasis results from a multi-step cascading process that includes: 1) vascularization of the primary tumor; 2) detachment and invasion of cancer cells; 3) intravasation into lymphatic and blood vessels; 4) survival and arrest in the circulation; 5) extravasation into distant organs; and 6) colonization and growth of metastatic tumors. microRNAs (miRNAs) play critical roles in this multi-step process, both promoting and suppressing metastasis. This review updates the progress made in understanding the roles of miRNAs for invasion and metastasis during cancer progression. A specific miRNA signature of cancer metastasis is also reviewed.
癌症转移是一个多步骤的级联过程,包括:1)原发性肿瘤的血管生成;2)癌细胞的脱离和侵袭;3)侵入淋巴管和血管;4)在循环系统中存活和滞留;5)外渗至远处器官;6)转移性肿瘤的定植和生长。微小RNA(miRNA)在这一多步骤过程中发挥着关键作用,既能促进也能抑制转移。本综述更新了在理解miRNA在癌症进展过程中对侵袭和转移作用方面所取得的进展。还综述了癌症转移的特定miRNA特征。
