Hormonal control of angiotensinogen production

Dzau, Victor J., Herrmann, Howard C.·1982·Life Sciences

Abstract

The renin-angiotensin-aldosterone system appears to be under neural and hormonal control. Plasma angiotensinogen concentration is elevated in Cushing's disease, during pregnancy and in women taking oral contraceptives. An in vitro liver slice system was used to study the hormonal control of angiotensinogen synthesis and release in the rat. Dexamethasone administration in vivo resulted in increase in the in vitro rate of release of angiotensinogen by liver slices into the incubation media. This increase was inhibited by actinomycin D, an inhibitor of protein synthesis and vincristine which blocks secretion. Similarly, ethinyl estradiol treatment resulted in a 50% increase in angiotensinogen production. Hyperthyroid state was achieved by injecting rats with L-thyroxine daily for seven days. Hepatic production rate of angiotensinogen rose 21/2-fold above control and was accompanied by increases in plasma angiotensinogen concentration and plasma renin activity. In contrast, plasma angiotensinogen concentration and plasma renin activity were reduced in thyroidectomized rats. The rate of angiotensinogen production by liver slices of these rats decreased by five-fold below that of intact animals. These changes were largely corrected when thyroidectomized rats were treated with replacement doses of L-thyroxine. We conclude that hepatic angiotensinogen biosynthesis is under hormonal control. Glucocorticoid, estrogen and thyroid hormones all stimulate angiotensinogen production. These…

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.
