Molecular size characterization of oxytocin receptors in rabbit amnion.

abstract：:A functioning rat thyroid cell line (FRTL-5) responds acutely to the addition of TSH, norepinephrine, and the Ca2+ ionophore A23187 by a depression in iodide (I-) uptake levels. The decrease in I- content measured at the steady state depends on the presence of external Ca2+ and can be accounted for by an effect on sti...
