(A) Wnt3a activates YAP/TAZ in LRP5/6 DKO cells. LRP5/6 DKO MEFs were starved for 16 hr then stimulated with Wnt3a (100 ng/ml). LRP5/6 deletion was confirmed by western blot.
(B) LRP5/6 are required for Wnt3a–induced expression of β-catenin target gene Axin2, but not YAP/TAZ target gene Ctgf. Wnt3a–induced expression of Axin2 and Ctgf mRNA was measured by qRT-PCR in control and LRP5/6 DKO MEFs for 0, 2, 4 hr.
(C and D) Experiments similar to panels A and B were performed in 3T3-L1 cells. Data are presented as mean ± SEM.
