Notch activation induced integrin α9, FNEIIIA and Cx37 in HdLECs. HdLECs were adenovirally infected with N1IC, N4int3, Hey1, Hey2 or lacZ-coding viruses. RNA and protein isolated 48 h post-infection. (A) qRT-PCR for α9 and FACs for integrin α9/β1. (B) qRT-PCR for fibronectin transcripts with EIIIA (FN-EIIIA+) and without EIIIA (FN-EIIIA−). Western blots for FN-EIIIA, total fibronectin or α-tubulin. (C) qRT-PCR and western blot for Cx37. Data are mean±s.d. *P≤0.05, **P≤0.005.
