Gicerin is an immunoglobulin superfamily cell adhesion molecule purified from chicken gizzards. This molecule displays an adhesive interaction with a laminin-like protein as well as with gicerin itself. Gicerin appears in embryonic tissues and plays a role in chick development through its cell adhesive properties. An increase in gicerin expression is found in some sporadic tumors of the chicken. To elucidate the possible role of gicerin in tumor progression in chickens, we introduced gicerin cDNA into an endogenous gicerin negative lymphoma MDCC-MSB1 cell line, and subsequently analyzed them for changes in their metastatic potentials. After intravenous implantation of the gicerin transfectants into chickens, the metastatic potential to the lung, liver and kidney was enhanced compared with parental MDCC-MSB1 cells. Self-aggregation activity was increased in gicerin transfectants. In addition, adhesive and migratory activities of the gicerin transfectants to the gicerin ligands were enhanced in vitro. These findings indicate that gicerin can contribute to the malignancy and metastatic properties of lymphoma.
