Estrogen Regulation of Angiotensin-Converting Enzyme mRNA
Abstract
Abstract—Estrogen replacement therapy is cardioprotective in postmenopausal women; however, the precise molecular mechanisms for this modulation are not fully elucidated. We previously showed that chronic estrogen replacement therapy reduced angiotensin-converting enzyme (ACE) activity in tissue extracts and serum with an associated reduction in plasma angiotensin II. A reverse transcriptase–polymerase chain reaction assay was developed to determine whether estrogen treatment regulates tissue ACE mRNA concentration. Total RNA was isolated from kidney cortex, kidney medulla, lung, and aorta of ovariectomized Sprague-Dawley rats after 21 days of chronic 17β-estradiol replacement therapy (5 mg pellet per rat SC) or placebo. A marked decrease in densitometric intensity ratios of amplified ACE cDNA to elongation factor-1α control cDNA was observed in all tissues from placebo-treated rats compared with the estradiol-treated rats (renal cortex: 0.29±0.04 versus 0.14±0.02; renal medulla: 0.37±0.04 versus 0.24±0.03; lung: 4.49±0.37 versus 2.49±0.59; and aorta: 0.41±0.04 versus 0.29±0.02; all P<0.05). A comparable reduction in ACE activity was detected in tissue extracts from kidney cortex, kidney medulla, and lung of hormone-treated animals. Incubation of purified rat lung ACE with 1 or 10 μmol/L 17β-estradiol had no effect on enzyme activity. These results suggest that estrogen treatment regulates tissue ACE activity by reducing ACE mRNA concentrations. Thus, the beneficial cardiovascular effects of estrogen may be mediated in part by downregulation of ACE with a consequent reduction in the circulating levels of the vasoconstrictor angiotensin II, a decrease in the metabolism of the vasodilator bradykinin, and an increase in the production of the vasorelaxant angiotensin-(1–7).

The cited source says what the claim attributes to it.
In the citing paper
“Researchers have reported that both ACE expression and activity are inhibited by estrogen in rodent models [26-29].”
The check wasn’t confident either way, so it gives no verdict — never disputed.
In the citing paper
“Plasma APP activity has been shown to form a continuous distribution in the general population (Cyr et al. 2001), suggesting that plasma APP activity is a complex quantitative trait likely influenced by multiple genetic loci and nongenetic factors (e.g., smoking and hormone replacement therapy [Gallagher et al. 1999]).”

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.
