Cyclic AMP-dependent protein kinase promotes glucocorticoid receptor function.

Abstract

Murine lymphoma cell lines such as WEHI-7 exhibit a cytolytic response to both cAMP and glucocorticoids. We have exploited this behavior to ask if cyclic AMP-dependent protein kinase plays a role in regulating glucocorticoid receptor function. We have found that cAMP-resistant cell lines containing a defective cAMP-dependent protein kinase activity give rise to spontaneous steroid-resistant variants at a high frequency (approximately 10(-7)) relative to wild type cells (less than 10(-10)). Unlike previous results with wild type cells, nearly complete loss of glucocorticoid receptor function was observed in a single selection using unmutagenized cAMPr derivatives of WEHI-7. Thus, the initial selection of the cAMPr phenotype serves as a permissive step toward the acquisition of glucocorticoid resistance in WEHI-7. In addition, cAMP was found to increase the levels of steroid binding in these cell lines, and the dose response was dependent upon the phenotype of the cyclic AMP-dependent protein kinase. The results demonstrate an important role for cAMP in regulating glucocorticoid receptor activity and strongly suggest that this novel two-step selection scheme leads to the isolation of new forms of glucocorticoid resistance.

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.
