Abstract

OBJECTIVE To determine the expression and biological roles of SGK1 in tissues and cells from patients with endometriosis and from healthy controls. DESIGN Case-control. SETTING University research setting. PATIENTS Premenopausal women. INTERVENTIONS Endometriotic tissues (E-Osis) were obtained from women with ovarian endometriosis and normal endometrial tissues (NoEM) were obtained from women undergoing hysterectomy for benign conditions. MAIN OUTCOMES MEASURES Expression levels of serum and glucocorticoid regulated kinase (SGK1), the role of SGK1 in E-Osis pathology, and the regulation of SGK1 by ERβ. RESULTS Transcript and protein levels of SGK1 were significantly higher in endometriotic tissues and cells compared to normal endometrium. SGK1 mRNA and protein levels were stimulated by estradiol, by the ERβ-selective agonist, diarylpropionitrile, and by prostaglandin E2. SGK1 was transcriptionally regulated by ERβ based on siRNA knockdown and chromatin immunoprecipitation of ERβ followed by quantitative PCR (ChIP-qPCR). SGK1 knockdown led to increased cleavage of PARP, and SGK1 activation was correlated with the phosphorylation of FOXO3a, a pro-apoptotic factor. CONCLUSIONS ERβ leads to SGK1 overexpression in endometriosis, which contributes to the survival of endometriotic lesions through inhibition of apoptosis.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Estrogen promotes endometriotic cell survival, inflammation and lesion progression.

    “This emphasizes the paramount importance of estrogen to the pathogenesis of endometriosis: estrogen promotes endometriotic cell survival, inflammation and lesion progression”

    From Endometriosis and nuclear receptors (2019) · cites this paper as Monsivais et al., 2016

    The Discussion reports that ERβ signaling supports endometriotic stromal-cell survival and cites evidence that ERβ gain-of-function contributes to lesion establishment and progression in mice. The Introduction says inflammation correlates with ERβ levels, but the paper does not establish that estrogen promotes inflammation. Page numbers are unavailable in our copy. (LLM, conf=0.85)

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.
