Catecholamine stimulation of iodothyronine 5'-deiodinase activity in rat dispersed brown adipocytes.

abstract：:Continuously superfused rat anterior pituitary cells were used to study the effects of prostaglandins (PGs) and a thromboxane (TX) on the secretion of TSH. Indomethacin, a blocker of PG synthetase, inhibited the amount of TSH secreted in response to TRH. This reduction in TRH responsiveness was overcome by administrat...
