    K + channel contributions to whole-cell current vary between cells adapted to 5 kPa or 18 kPa O 2 . ( A) Raw current traces under indicated conditions recorded from HUVEC exhibit outward rectifying whole-cell currents. ( B) Comparisons of normalised current amplitudes (relative to current at +50 mV) under indicated conditions show current inhibition relative to basal control from cells cultured at 5 kPa or 18 kPa using 10 mM TEA, 5 μM TRAM-34, 100 nM apamin (5 kPa: Basal vs. TEA: P = 0.0381, Basal vs. TEA + TRAM-34: P = 0.0095, Basal vs. TEA + TRAM-34+apamin: P = 0.0022; 18 kPa: Basal vs. TEA: P = 0.03723, Basal vs. TEA + TRAM-34: P = 0.0076, Basal vs. TEA + TRAM-34+apamin: P = 0.0042; two-way ANOVA, data denote mean ± S.E.M.).
