Cytofluorimetric and biochemical analysis in two different grade human bladder cancer cell lines showed that G3 EJ cells exhibited higher levels of alpha5beta1 and alpha6beta1 heterodimers, and the G2 RT112 cell line higher levels of alpha2beta1. Alpha6/beta4 receptor was detected only in RT112 cells. Adhesion assays with extracellular matrix proteins indicated that both cells bound to fibronectin, laminin and collagen 1, the adhesive properties being related to the integrin profile. Inhibition tests revealed that alpha5beta1 mediated adhesion to fibronectin, alpha3beta1 and alpha6beta1 to laminin, and that alpha2beta1 was the main mediator of adhesion to collagen I in both cell lines. In EJ but not in RT112 cells, tumor necrosis factor-alpha induced the upregulation of alpha2, which mediated increased adhesion to collagen I. The different effects of TNFalpha on the two cell lines were not attributable to differences in tumor necrosis factor responsiveness, as both cells expressed comparable levels of tumor necrosis factor receptor-1 and the tumor necrosis factor-inducible intercellular adhesion molecule-1.
