Blebbistatin (B05060), low-endotoxin BSA (A8806), PA (P9767), and Y27632 (Y0503) were from Sigma Aldrich (St. Louis, MO), while cis-PO/palmitoleic acid (10009871) was from Cayman Chemicals (Ann Arbor, MI). Antibodies used for immunoblotting were α-actinin (Millipore Sigma; A7811), β-actin (Cell Signaling; 4790), α-catenin (ThermoFisher; 13-9700), β-catenin (BD Biosciences; 610153), VE-cadherin (Santa Cruz; 9989), RhoA (Santa Cruz; c-418), IRDye 800CW goat anti-rabbit immunoglobulin G (IgG) (LI-COR; 9253211), and IRDye 680LT goat anti-mouse IgG (92668070). Antibodies and reagents used for immunofluorescence were α-catenin (ThermoFisher; 13-9700), β-catenin (BD Biosciences; 610153), DAPI (4’,6-Diamidino-2-phenylindole, dihydrochloride; ThermoFisher; D1306), GM130 (BD Biosciences; 610823), phospho-MLC (Cell Signaling; 3674), phalloidin (Alexa Fluor 555) (ThermoFisher; A34055), phospho-YAP S127 (Abcam; 76252), YAP (Cell Signaling 14074), VE-cadherin (Santa Cruz; 9989), goat anti-rabbit IgG secondary antibody (Alexa Fluor 488) (ThermoFisher; A11008), goat anti-mouse IgG secondary antibody (Alexa Fluor 647) (ThermoFisher; A21235). Dako fluorescence mounting medium (S3023) was from Aligent. Y227632 (Y0503) was from Millipore Sigma (Burlington, MA). The plasmid encoding GFP–β-actin was kindly provided by Sergio Grinstein (Hospital for Sick Children, Toronto, Ontario, Canada).

Protein lysates were prepared from cells using RIPA buffer supplemented with a protease inhibitor cocktail (Roche, China). Protein lysates were separated by SDS-PAGE and then transferred to PVDF membranes (Sigma, United States). Membranes were then incubated with specific antibodies. Protein expression was assessed using ECL chemiluminescent reagents. The primary antibodies used are as follows: antibodies against ATG5, LC3, and β-actin were purchased from Cell Signaling Technology (United States) and those against phospho-PI3K (Tyr458), PI3K, phospho-AKT (Ser473), AKT, phospho-mTOR (Ser2248), mTOR, phospho-YAP (S127), and YAP were purchased from Abcam (United Kingdom).
