COL11A1 promoted EMT via the AKT/GSK-3β/Snail signaling pathway: (A) Western blotting results showing the expression levels of EMT markers and MMP-2/9 in PANC-1 cells transfected with pCMV3-COL11A1, LY294002, and siGSK-3β; (B) the sequence and position of the Snail binding site in the E-cad promoter are shown. Chromatin immunoprecipitation (ChIP) of Snail in the E-cad promoter. PANC-1 cells were transfected withpCMV3-COL11A1, siCOL11A1, siGSK-3β, and LY294002; (C) immunofluorescence analysis of E-cad expression levels in PANC-1 cells transfected with pCMV3-COL11A1, LY294002, siGSK-3β, and siSnail (×100); (D) the images show the adhesion ability of the indicated cells after different treatments.
