Histo-blood group A/B antigen deletion/ reductionvs. continuous expression in human tumor cells as correlated with their malignancy

Abstract excerpt

Deletion or reduction of histo-blood group A or B antigen in tumors of A or B individuals is clearly correlated with the degree of malignancy and metastatic potential in many types of human cancer. Haptotactic motility of A+H- or B+H- colonic or gastric tumor cell lines produced by transfection of A or B gene was significantly lower than that of parental A-H+ or B-H+ cells. This is ascribable to reduced function...
