Key result
Injection of xKv3.1 antisense RNA into Xenopus embryos reduced delayed rectifier potassium current density by 62% and increased action potential duration from 1.9 ms to 3.5 ms in spinal neurons.
Absolute Event Rate: 3.5% vs 1.9%
p-value: p=<0.01
Antisense suppression of xKv3.1 demonstrates its critical role in the maturation of delayed rectifier potassium current and action potential duration in developing spinal neurons.

Hypothesis-generating for Kv channel roles in neuronal maturation; leaves open in vivo validation and mammalian translation.
Vincent et al. (2000) studied this question. xKv3.1 antisense (AS) RNA vs. Uninjected cells, nonfluorescent cells, or sense RNA injected cells was evaluated on Delayed rectifier potassium current (IKv) density and action potential duration (p=<0.01). Injection of xKv3.1 antisense RNA into Xenopus embryos reduced delayed rectifier potassium current density by 62% and increased action potential duration from 1.9 ms to 3.5 ms in spinal neurons.
