A Double IF staining detected the distribution of exogenous ATG9B (yellow colour) in SW480 cells transfected with vector, ATG9BHis or ΔATG9BHis (deleted mutation with aa368–411 of ATG9B). The magnified parts are displayed in lower panel, scale bar 10 μm. B IF staining to detect pY397-FAK (red) expression in the indicated cells. The magnified parts are displayed in lower panel, scale bar 10 μm. C Immunofluorescence images of pY118-Paxiilin in SW480/ATG9BEGFP cells after treatment with 10 μM nocodazole (NZ) for 4 h followed by washout for the indicated times, scale bar 10 μm. The magnified parts of vector cells (dotted line) and ATG9BEGFP overexpression cells (solid line) were, respectively, displayed. Mean intensity levels of surface pY397-Paxillin at the indicated times of NZ washout is presented in the right panel (n = 20 cells analysed per group). D Time-limited FN adhesion assay to detect the rate of FA formation in the indicated cells for 30 min. Scale bar 50 μm (n = 5). Data information: Graphs report mean ± SEM. Significance was assessed using two-tailed Student’s t test. ***P < 0.001, **P < 0.01, NS, no significance.
