胃癌是一种常见的消化道恶性肿瘤,发病率较高,而胃癌转移是患者致死的主要原因之一。肿瘤细胞的转移是一个复杂的过程,它包括黏附、降解和移动。肿瘤细胞从连续的黏附接触和黏附解除中获得移动的牵引力,所以浸润和移动的过程首先是黏附和去黏附的交替过程。随着近十余年来分子 Gastric cancer is a common gastrointestinal cancer, the incidence is higher, and gastric cancer is one of the major causes of death in patients. Tumor cell metastasis is a complex process that involves adhesion, degradation and movement. Tumor cells gain traction by continuous adhesion and adhesion release, so the process of invasion and migration is first of all an alternating process of adhesion and de-adhesion.
