英文摘要：

Galectins can recognize and specifically bind to β-galaetosidase, and regulate the transformation and survival of tumor cells, and promote the migration and metastasis of tumor cells, etc. Galectins correlate with tumor diagnosis, progression and prognosis. Galectins also can serve as immunoregulatory molecules to regulate the survival, activation, proliferation and differentiation of immune cells, and are components of tumor immune microenvironment.
