Figure Lengend Snippet: A. Representative curve of cell index measurement for rat VSMC adhering on gelatin coating without (grey) and with ANGPTL6 (4 ng/mL, blue). B . Quantification of the rate of VSMC adhesion on gelatin coating without or with ANGPTL6 (1-4 ng/mL) using the slope of the cell index curve in its linear part (One-way ANOVA; *** P < 0.001). C. Representative images of the evan blue staining of rat VSMC that transmigrated across a porous membrane coated with gelatin containing or not ANGPTL6 after 24 h (left) and the corresponding quantification of the area covered by rat VSMC (normalized to the gelatin alone condition, Wilcoxon t -test) D. Representative curve of cell index measurement for human VSMC adhering on gelatin coating without (grey) and with ANGPTL6 (4 ng/mL, blue) (left) and corresponding quantification of the rate of adhesion using the slope of the cell index curve in its linear part (Wilcoxon t -test; * P <0.05). F. Single-cycle kinetic SPR analysis of the ANGPTL6 interaction with αVβ5 or α5β1 integrins (12.5 nM; 25 nM; 50 nM; 100nM and 200 nM) or fibronectin (62.5 nM; 125 nM; 250 nM; 500 nM and 1000 nM). The red line represents the kinetic global fit of the ANGPTL6-αVβ5 interaction using 1:1 Langmuir model.
Article Snippet: SPR was used to assess the interaction between fibronectin (ECM001, Sigma-aldrich), αVβ5 integrin (2528-AV, R&D systems) and α5β1 integrin (3230-A5, R&D systems) with ANGPTL6 (CSB-MP822824HU, Cusabio) immobilized onto CM5 (1000 RU; GE Healthcare) using a Biacore T200 (GE Healthcare).
