Time course of the change in nuclear 3,5,3'-triiodothyronine receptors of skeletal muscle in relation to energy intake.
Nuclear triiodothyronine receptors have been investigated in skeletal muscle from young pigs living at thermal neutrality (26 degrees C). Animals were fed at a high (H) or low (L) level of energy intake for 3 or 21 days and killed at 6 or 24 h after the last meal. Receptor numbers were significantly greater on the H than the L intake, even after only 3 days of treatment. The difference in receptors between animals on H and L diets was somewhat less at 6 compared with 24 h after feeding. It is postulated that these changes could be mediated through the action of glucagon.
