LGALS3 and carcinoma: A study indicated that interactions of surface adhesion molecules like galectin-3 and Thomsen-Friedenreich antigen (T antigen) are involved in carbohydrate-mediated metastatic cell heterotypic (between carcinoma cells and endothelium) and homotypic (between carcinoma cells) adhesion (Zou et al., 2005); and similar phenomena was found in another study with different cancer cells (Khaldoyanidi et al., 2003).
