Effect of overexpression of GSK3β on G17-induced migration. (A). Subconfluent AGSE cells were transiently transfected with Empty Vector, GSK3β-WT, GSK3β-KA mutant or GSK3β-S9A mutant vectors. The cells were wounded linearly 48 hours post-transfection and, after an overnight recovery following wounding, they were treated with G17 and pictures obtained at the indicated times. (B) AGSE cells were transfected as in 4A followed by G17 treatment and wound healing assay. The distance of migration of the wounded edges for each time point were measured at several places and the average distance was represented by bar diagrams as "Average Gap". (C) AGSE cells transfected in A and treated with G17 were analyzed for protein expression. Western Blot analysis was performed with an HA.11 antibody to detect ectopic HA-tagged GSK3β proteins and with β-catenin and GAPDH antibodies to detect the corresponding endogenous proteins.
