    Integrin β6 is a proteolysis‐resistant mediator of CRC tumour cell adhesion to endothelial cells. (A) Lysates of HT‐29 and DLD‐1 cells harvested in the presence of 0.05% trypsin or 5 mM EDTA‐PBS were collected, and the expression of integrins αv, β6, β1 and β5 was analysed using western blotting. Blots show the full‐length proteins as well as the trypsin‐induced protein fragments. GAPDH was used as a loading control. (B) Adhesion of cytopainter‐stained ITGB6 KO or NT cells harvested by trypsinization or 5 mM PBS‐EDTA to an IL‐1β‐stimulated HUVEC monolayer under static conditions. Arrow points towards an adherent cell. Scale bar: 250 μm. The quantification is shown below. Mann–Whitney U test; ns, not significant; ** p < 0.01. (C) The cancer‐related survival (60‐month cut‐off) of CRC patients who did not receive neoadjuvant therapy and had no residual tumour (R0) was explored. Based on MMP11 <t>and</t> <t>MMP12</t> RNA expression levels, patients were divided into high‐ and low‐MMP groups. ITGB6 ‐dependent survival was investigated in these groups. The number of patients per group is indicated by ‘ n ’. Cox proportional hazards survival regression. (D) Recombinant integrins αvβ6, αvβ1, and αvβ5 were incubated with MMP‐12 at an enzyme‐to‐substrate ratio of 1:10 for 1 h. Proteolytic cleavage of integrins was evaluated via western blotting.
