    Pdgfb is a Notch-independent target of β-catenin signaling in ECs. (A) HUVECs co-cultivated with control −D , Wnt1 −D , and Dkk1 −D GL261 cells. qRT-PCR ( n = 4) for human PDGFB regulated by Wnt1 −D or Dkk1 −D (ns) compared with control −D (gray line; *, P < 0.05). (B) qRT-PCR for Pdgfb gene regulated in MBEs stimulated by Wnt3aCM for 18 and 48 h compared with controlCM (gray line; n = 4; *, P < 0.05; ***, P < 0.001). (C, left) qRT-PCR for Axin2 and Pdgfb regulated in β-catenin–deficient ECs transduced with LefΔN-βCTA compared with the vector control (gray line; n = 4; *, P < 0.05; **, P < 0.01). (right) Representative Western blot ( n = 1) for PDGF-B from LefΔN-βCTA ECs compared with the vector control; top band shows the nonreduced (PDGF-BB) and bottom band reduced protein (PDGF-B). Densitometric analysis shows the summarized values for both forms of PDGF-B of samples loaded twice. (D) qRT-PCR of β-catenin–deficient ECs (control) or transduced with LefΔN-βCTA grown for 24 h either on gelatin- or Dll4-coated dishes ( n = 3). Notch pathway induction was monitored by Hes1 expression (*, P < 0.05; **, P < 0.01). Notch signaling was blocked by Dll4-Fc. Error bars indicate SEM.

    PDGF-B is up-regulated in the tumor endothelium upon Wnt1 expression. (A) Representative ISH for Pdgfb of subcutaneous Wnt1 +/−D tumors. Asterisks indicate vessels, and arrowheads point to Pdgfb + ECs. Insets show representative vessels in higher magnification. Bars: (full images) 50 µm; (insets) 18 µm. (B, left) Representative picture of isolated subcutaneous tumor vessels and dot blot for von Willebrand factor (vWF). (right) Representative Western blot for PDGF-B with pooled subcutaneous tumors vessels ( n = 2 tumors/group). Densitometric analysis for PDGF-B of five independent Western blot experiments. Error bars indicate SEM.
