ARA-S facilitated the activation of Kv7.1/KCNE1 channels from all tested species, with rabbit channels displaying quantitatively similar effects to human channels, and guinea pig channels showing a more prominent increase in current amplitude and maximal conductance.

Why the study?

To guide the selection of animal models for assessing ARA-S effects and aid interpretation across experimental models, it is useful to determine whether Kv7.1/KCNE1 channels from relevant species respond similarly to ARA-S.

Guinea pig, rabbit, and human Kv7.1/KCNE1 channels expressed in Xenopus laevis oocytes

Comparison

Effects of ARA-S across Kv7.1/KCNE1 channels from guinea pig, rabbit, and human

Overview

Supports exploration of ARA-S across cardiac models; leaves open translation to human arrhythmia therapy.

Structured PICO

Population

I
Intervention
N-arachidonoyl-L-serine (ARA-S)

Outcome
Effects on Kv7.1/KCNE1 channels (voltage-dependence of channel opening, current amplitude, and conductance)surrogate

ARA-S facilitates the activation of Kv7.1/KCNE1 channels across species, suggesting rabbit and guinea pig models are suitable for studying its cardiac electrophysiological effects.
