Wnt 10b activates the CCN2 promoter in NIH 3T3 fibroblasts through the Smad response element.
Wnt proteins elevate expression of the CCN family. For example, Wnt10b induces the fibrogenic pro-adhesive molecule connective tissue growth factor (CTGF, CCN2) in NIH 3T3 fibroblasts. Wnt10b activates the CCN2 minimal promoter. In this report, we map the Wnt10b response element in the CCN2 minimal promoter to the previously identified Smad response element. These results suggest that Wnts may cross-talk with the Smad signaling pathway to induce fibrotic responses in fibroblasts.
