In parental SCC12 cells, the latent 92-kDa form of MMP-9 was coimmunoprecipitated with alpha5beta1 regardless of the presence of fibronectin. Overexpression of GM3 in the presence of absence of fibronectin blocked the association between alpha5beta1 and MMP-9. Depletion of GM3 by either stable overexpresion of ganglioside-specific sialidase or treatment with PPPP increased the association of both cleaved and precursor MMP-9 with alpha5beta1, regardless of the presence or absence of fibronectin. Overexpression of GT1b did not affect the association of MMP-9 with integrin alpha5beta1.
