a Gene Set Enrichment Analysis (GSEA) was performed to exploring FSTL1 effect in CRC. (i) KEGG-Focal adhesion, normalised enrichment score (NES) = 2.019, nominal P value (NOM P) = 0.000, false discovery rate (FDR) = 0.063. (ii) KEGG-Regulation of actin cytoskeleton, NES = 1.893, NOM P = 0.000, FDR = 0.080. (iii) PID-Integrin1 pathway, NES = 1.631, NOM P = 0.004, FDR = 0.407. (iv) KEGG-Focal adhesion, NES = 1.697, NOM P = 0.026, FDR = 0.464. b Western blotting analysis was performed to detect the expression of FSTL1 and the main members of focal adhesion signalling pathway in indicated stable cells. Phosphorylated FAK at Tyr-397, Phosphorylated Paxillin at Tyr-118, and Phosphorylated SRC at Tyr-418. c Immunofluorescent staining was performed to observe the expression of FAK (green, upper panel), p-FAK (green, lower panel) and actin cytoskeleton in DLD1-Vector and DLD1-FSTL1 cells (×1800, scale = 10 μm). Phalloidin (red) stains F-actin, DAPI (blue) stains nuclei. Right column are the partial enlarged details from the white pane of corresponding original images
