Figure 6. Second messenger signaling in response to AM-8123 and pyr-apelin-13 treatment.
(A) Both AM-8123 and pyr-apelin-13 result in ERK phosphorylation in HUVECs grown under hypoxic conditions. Additionally, AM-8123 and pyr-apelin-13 exhibit a dose-dependent increase in both (B) ERK and (C) AKT phosphorylation in CHO cells overexpressing hAPJ. See full blots in Supplemental Figure 23.
