Vessels were preconstricted to 30% to 50% of maximal diameter with phenylephrine (1 to 3 μmol/L). Emax are expressed as the percentage of the maximal diameter. Data presented as mean±SEM of (n) mice. The Kruskal–Wallis test followed by the Dunn's posttest were used. KD indicates knockdown; WT, wild‐type; LNNA, Nω‐nitro‐l‐arginine; Indo, indomethacin.
