Stimulation of DNA synthesis in nuclei isolated from rats injected with HSA. Animals were injected with HSA, T, or saline and nuclei were isolated 20 hours later. [3H] TTP incorporation was determined as described in “Methods”.
2A Injections into normal rats: ●——●, injection of T3 200 μg/100 g; x——x, HSA from weanling rats; ○——○, saline.
2B Injections were made into animals that had 40% of their liver removed 4 hours before the injection. ●——●, HSA from T3,-injected rat; x——x, HSA from weanling rats; ○——○, saline.
