Abstract

Estrogenic hormones, believed to exert most of their effects via the direct interaction of their receptors with chromatin, are found to increase cAMP in target breast cancer and uterine cells in culture and in the intact uterus in vivo. Increases in intracellular cAMP are evoked by very low concentrations of estradiol (half maximal at 10 pM) and by other physiologically active estrogens and antiestrogens, but not by an inactive estrogen stereoisomer. These increases in cAMP result from enhanced membrane adenylate cyclase activity by a mechanism that does not involve genomic actions of the hormones (are not blocked by inhibitors of RNA and protein synthesis). The estrogen-stimulated levels of cAMP are sufficient to activate transcription from cAMP response element-containing genes and reporter plasmid constructs. Our findings document a nongenomic action of estrogenic hormones that involves the activation of an important second-messenger signaling system and suggest that estrogen regulation of cAMP may provide an additional mechanism by which this steroid hormone can alter the expression of genes.

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.
