Abstract

Objective To investigate steroidogenesis in eutopic and ectopic endometrial tissues in adenomyosis.Study design Aromatase and estrone sulfatase activities were determined by anion-exchange resin column chromatography, thin-layer chromatography, and cocrystallization. The effects of danazol on the activity of these enzymes were also examined. Moreover, localization of aromatase in eutopic and ectopic endometrial tissues was immunohistochemically examined with antihuman placental aromatase cytochrome P-450 antibody.Results Aromatase and estrone sulfatase activities were detected in ectopic endometrium. The activity of these enzymes was significantly suppressed by danazol. In addition, aromatase was immunohistochemically detected in glandular cells of eutopic and ectopic endometrial tissues.Conclusions The results suggest that estrogen is synthesized in the eutopic and ectopic endometrial tissues of women with uterine adenomyosis and that it may affect the growth of adenomyosis. Danazol suppressed synthesis of estrogen in vitro.

Claims other papers make about this one

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

  • The results of activated estrogen signaling and reduced ERα expression in OE and AD lesions are consistent with overwhelming data showing the same.

    “Our results of activated estrogen signaling as well as reduced ERα expression in OE and AD lesions are consistent with overwhelming data showing the same (Yamamoto et al., 1993; Brandenberger et al., 1999; Fujimoto et al., 1999; Attar et al., 2009; Mehasseb et al., 2011; Heublein et al., 2012; Samartzis et al., 2012).”
  • Genes involved in estrogen biosynthesis, such as StAR and P450 aromatase, are upregulated in adenomyosis.

    “In addition, genes involved in estrogen biosynthesis, such as steroidogenic acute regulatory protein (StAR) and P450 aromatase, are upregulated in adenomyosis [48,49].”

    From The Pathogenesis of Adenomyosis vis-à-vis Endometriosis (2020) · cites this paper as [49]

  • Increased local production of estrogen is common to all subtypes of endometriosis and even to adenomyosis.

    “Moreoever, increased local production of estrogen is common to all subtypes of endometriosis83 and even to adenomyosis84.”
  • Expression of P450 aromatase is increased in adenomyotic tissue and in ectopic and eutopic endometrium of women with endometriosis.

    “The expression of the P450 aromatase is increased in adenomyotic tissue and in the ectopic and eutopic endometrium of women with endometriosis [35–41].”

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.
