Figure 2. Sox7 is able to negatively regulate Wnt/β-catenin signaling activity.
(A) Sox7 could reduce Wnt-1 induce TOPFLASH luciferase activity dose dependently in HEK293 cells. FOPFLASH luciferase activity was used as a negative control. (B) Transient transfection of Flag/Sox could remarkably reduce the expressions of C-myc and cyclinD1 in HEC1A (wild-type β-catenin) and TOV112D (mutant β-catenin) cells.
