CD24 functions as ligand to P-selectin, by virtue of which it facilitates interaction with platelets or endothelial cells, thereby increasing metastatic potential of tumour. CD24 expression has been identified as a prognostic marker in variety of tumors (Kristiansen et al., 2003a; 2003b; Sung et al., 2010; Choi et al., 2007; Chou et al., 2007; Sano et al., 2009). This evidence concerns the gene CD24 and neoplasm.
