12 , apelin-13 stimulation elicited a further increase in the HUVEC cell index (CI); however, co-stimulation with interference peptides corresponding to TMD1, which was demonstrated to disrupt APJ homodimers, led to a decreasing trend in the CI compared to that before treatment, suggesting disruption of APJ homodimers induced distinct cell responses after agonist stimulation.
