Title: Ontogeny of the cytosolic receptor for 2,3,7,8-tetrachlorodibenzo-p-dioxin in rat liver, lung, and thymus.

Abstract: The ontogeny of the cytosolic receptor for 2,3,7,8-tetrachlorodibenzo-p-dioxin was studied in Sprague-Dawley rats by quantitation of the receptor in hepatic, lung, and thymic cytosol. Concentrations of hepatic and lung cytosolic receptors increased rapidly after birth and remained at the highest levels from days 2 to 21. After this time, receptor levels in these tissues slowly declined with age. In the thymus, cytosolic receptor concentrations remained high from days 2 to 42 following birth. In these tissues and at all times examined, the receptors demonstrated very high affinities for [3H]2,3,7,8-tetrachlorodibenzo-p-dioxin. From days 15 to 42 following birth, no consistent sex related differences in receptor content or affinity were observed in any of these tissues.
