Abstract

Objective To test the hypothesis that the expression of the different isoforms of the estrogen receptor alpha (ER-α) and beta (ER-β) and the progesterone receptor A (PR-A) and B (PR-B) would be differentially modulated in uteri with adenomyosis compared with controls and that modulation would be related to the menstrual cycle.Design Case control, blinded comparison.Setting University department.Patient(s) 54 premenopausal women with and 35 without uterine adenomyosis as the sole pathology.Intervention(s) Multiple samples studied using immunohistochemistry for estrogen and progesterone receptors.Main outcome measure(s) Histomorphometric analysis of receptor expression.Result(s) The ER-α expression in the adenomyotic endometrium was different from that of the normal endometrium and the foci in the midsecretory phase of the cycle, but expression of ER-α in the inner and outer myometrium was not statistically significantly different. The ER-β expression was statistically significantly elevated in the adenomyotic functionalis gland during the proliferative phase and throughout the myometrium across the entire menstrual cycle. Expression of PR-A was similar to that of PR-B, with reduced expression in the basalis stroma, and inner and outer myometrium in the adenomyotic samples. The pattern of ER-β, PR-A, and PR-B expression was similar in the endometrial basalis and adenomyotic foci.Conclusion(s) These data suggest ER-β expression and the lack of PR expression are related to the development and/or progression of adenomyosis and might explain the poor response of adenomyosis-associated menstrual symptoms to progestational agents.

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

  • The finding of reduced ERα expression agrees with previous reports.

    “Our finding of reduced ERα expression agrees with previous reports (Brandenberger et al., 1999; Mehasseb et al., 2011).”
  • The endometrium of endometriosis patients displays aberrant molecular expression patterns that give it the ability to implant, invade, and develop into endometriotic foci.

    “which have demonstrated that the endometrium of endometriosis patients displays aberrant molecular expression patterns that give it the ability to implant, invade, and develop into endometriotic foci (27)(28)(29)(30).”

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.
