The levels of the transcribing RNA polymerase I(B) in the nucleus and of the non-transcribing RNA polymerase I(A) in the cytoplasm are both approximately doubled 24 h after a single i.p. injection of triiodothyronine into thyroidectomized rats. This suggests that the triiodothyronine-induced stimulation of ribosomal RNA synthesis is associated with an increase in the total RNA polymerase I content of rat liver cells.
在对甲状腺切除的大鼠进行一次腹腔注射三碘甲状腺原氨酸24小时后，细胞核中转录性RNA聚合酶I（B）的水平以及细胞质中非转录性RNA聚合酶I（A）的水平均大约增加了一倍。这表明三碘甲状腺原氨酸诱导的核糖体RNA合成刺激与大鼠肝细胞中RNA聚合酶I总含量的增加有关。
