Levels of sex hormone-binding globulin (SHBG) and corticosteroid-binding globulin (CBG) messenger ribonucleic acid (mRNAs) in ovarian endometriosis
Open accessAbstract
― Recently, much evidence has indicated that sex hormone-binding globulin (SHBG) and corticosteroid-binding globulin (CBG) play a role in the intracellular action of sex steroids in target cells.In the present work, expression of SHBG mRNA and CBG mRNA was demonstrated in tissues of human normal endometrium and pelvic endometriosis, using the reverse transcription-polymerase chain reaction (RT-PCR).SHBG mRNA levels were higher in pelvic endometriosis than in normal endometrium (P < 0.02), while CBG mRNA levels were lower than in normal endometrium (P < 0.05).The SHBG mRNA/CBG mRNA ratio was significantly higher in pelvic endometriosis than in normal endometrium (P < 0.01 These findings suggest that overexpression of intercellular SHBG in endometri- otic tissues results in the formation of the estrogen-predominant milieu, since SHBG-bound estrogen is considered to be protected from the metabolism in liver and available in endometrial cells, thereby assisting the development of the pelvic endometriosis.sex hormone-binding globulin / corticosteroid-binding globulin / mRNA I endometriosis Résumé ― Niveaux des ARN messagers de la globuline liant la testostérone (ARNm SHBG) et de la transcortine (CBG) dans l'endométriose ovarienne.Récemment, plusieurs travaux ont mon- tré que la SHBG et la CBG jouent un rôle dans l'interaction intracellulaire de stéroïdes sexuels dans les cellules cibles.Dans cette étude, l'expression des ARNm de la SHBG et de la CBG a été mise en évidence dans des biopsies d'endomètre humain normal et des prélèvements d'endométriose pelvienne par transcription réverse puis amplification en chaîne par la polymérase.La concentration de I ARNm SHBG est plus élevée dans l'endométriose pelvienne que dans l'endomètre normal (P < 0,02), les résultats inverses sont observés pour IARNm CBG (P < 0,05).Le rapport ARNm SHBG/ARNm CBG est significativement plus élevé dans l'endométriose pelvienne que dans l'endomètre normal (P < 0, 01).Étant donné que ¡'œstrogène lié à la SHBG semble être protégé du métabolisme hépatique et rendu disponible dans les cellules endométriales, toutes ces constatations suggèrent que, dans les tissus d'endométriose, l'augmentation de l'expression de la SHBG intracellulaire produisant un milieu où l'cestrogène est prédominant accentuerait un développement de l'endométriose pelvienne.globuline liant les hormones stéroïdes sexuels / transcortine lARNm / endométriose

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.
