In this study we investigated deiodinase 1 ( Dio1 ) , deiodinase 2 ( Dio2 ) , and deiodinase 3 ( Dio3 ) mRNA expression at the following life stages ( 2 , 8 , and 1k - cells ; 50 % - epiboly , 6 and 18 - somites , 22 , 24 , 48 , 72 hpf and / or 10 dpf ) in zebrafish and found life stage specific expression of these genes that were highly localized .
