(A) Tetracycline-regulated expression of BirA-MEKK3 drives dose-dependent expression of KLF2 and KLF4 in HUVEC. (B) siRNA knockdown of MEKK3 in HUVEC blocks flow-induced expression of KLF2, KLF4 and ADAMTS4. HUVEC were exposed to 16 hr of laminar shear after exposure to siRNA directed against MEKK3 (MAP3K3) or control, scrambled siRNA. N = 5; p < 0.0001. (C) qPCR of E10.5 hearts reveals severely reduced levels of Klf2, Klf4 and known KLF2/4 target genes following endocardial Mekk3 (Map3k3) deletion. N = 3 for all groups. (D) qPCR of E10.5 hearts reveals reduced levels of Nrg1 and Adamts5 but normal levels of FGFs following endocardial Mekk3 (Map3k3) deletion. N = 3 for all groups. (E) qPCR of E9.5 wild-type mouse hearts following 24 hr incubation in medium containing the MEK5 inhibitor BIX02188 (“BIX”) or DMSO (“control”). N = 3 for all groups. Error bars represent SEM. ∗p < 0.05; ∗∗p < 0.01; ∗∗∗p < 0.001; ∗∗∗∗p < 0.0001. |
