This review discusses the role of galectin-1 in the tumor microenvironment.
First, the structure and function of galectin-1 are discussed. Galectin-1, a
member of the galectin family of lectins, is a functionally dimeric
galactoside-binding protein. Although galectin-1 has both intracellular and
extracellular functions, the defining carbohydrate-binding role occurs
extracellularly. In this review, the extracellular roles of galectin-1 in cancer
processes are discussed. In particular, the importance of multivalent
interactions in galectin-1 mediated cellular processes is reviewed. Multivalent
interactions involving galectin-1 in cellular adhesion, mobility and invasion,
tumor-induced angiogenesis, and apoptosis are presented. Although the mechanisms
of action of galectin-1 in these processes are still not well understood, the
overexpression of galectin-1 in cancer progression indicates that the role of
galectin-1 is significant. To conclude this review, synthetic frameworks that
have been used to modulate galectin-1 processes are reviewed. Small molecule
oligomers of carbohydrates, carbohydrate-functionalized pseudopolyrotaxanes,
cyclodextrins, calixarenes, and glycodendrimers are presented. These synthetic
multivalent systems serve as important tools for studying galectin-1 mediated
cancer cellular functions.
