Thyroid hormone regulation of beta-adrenergic receptor number.

Abstract

The effects of exogenous thyroid hormones (thyroxine and triiodothyronine) on beta-adrenergic receptors in the rat myocardium were investigated. The potent beta-adrenergic antagonist, (-)-[3H]dihydroalprenolol, was used to directly estimate the number and affinity of beta-adrenergic receptors in rat heart membranes from control and hyperthyroid rats. Cardiac membranes from hyperthyroid rats contained 196 +/- 7 fmol of (-)-[3H]dihydroalprenolol binding sites/mg of protein which was significantly (p less than 0.005) greater than the number of binding sites (89 +/- 5 fmol/mg of protein) present in control membranes. The equilibrium dissociation constant (KD) for the interaction of receptors with dihydroalprenolol was the same (2 to 15 nM) in membranes from control and hyperthyroid rats. Similarly, there was no significant difference between the control and hyperthyroid membranes in the affinity of the beta-adrenergic receptor binding sites for the beta-adrenergic agonist isoproterenol. The results of this study demonstrate that thyroid hormones can regulate the number of cardiac beta-adrenergic receptors. The increased numbers of receptors may be responsible, at least in part, for the enhanced catecholamine sensitivity of beta-adrenergic-coupled cardiac responses in the hyperthyroid state.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
