Figure 2From: Characterization of maturation of neuronal voltage-gated sodium channels SCN1A and SCN8A in rat myocardium SCN5A mRNA expression. Expression of SCN5A mRNA steadily increased after birth compared to the embryonic level of development. The slight drop of mRNA expression after day 21 was not significant. Significance refers to the amount of mRNA on day 17 of embryonic development (Abbreviations and levels of significance as depicted in Figure 1).Back to article page
