The protein expression levels of WNT1 and important factors related to the WNT1/β-catenin signaling pathway in cells transfected with WNT1 wild-type and mutant plasmids. A The protein expression levels of WNT1 and other important factors related to the WNT1/β-catenin signaling pathway in the cells. B–D Semi-quantitative analysis of protein levels in graph A. * P < 0.05 and ** P < 0.01 indicate significant differences
