LGALS3 and acute lymphoblastic leukemia: GM-CT-01 and GR-MD-02 both inhibited human BCP-ALL migration, presumably by interfering with a signal produced by engagement of extracellular Galectin-3 and possibly Galectin-1 with an, as of yet unknown, receptor or alternatively, inhibit Galectin internalization and by this mechanism inhibit intracellular effects.
