Abstract

Endometriosis affects 6–10% of women in their reproductive years, causing chronic pelvic pain and infertility. Its pathogenesis remains poorly understood and current treatments, based on hormonal therapy or surgery, are often insufficient. The purpose of our study was to investigate the role of the ERK pathway in the development of endometriosis and to test the effects of protein kinase inhibitors on the proliferation of endometriotic cells in vitro and in vivo. We studied ex vivo human endometrial and endometriotic cells in culture. Stromal and epithelial cells were extracted from endometrial and endometriotic biopsies from patients with endometriosis and from patients without endometriosis. The ERK pathway was explored by western blot on cell lysates and by ELISA on total crushed specimens of endometrium. Cells in culture were treated with A771726, PD98059, and U0126. Human endometriotic lesions were implanted in nude mice. Mice were treated with A771726, leflunomide, PD98059, U0126 or PBS during 2 weeks before sacrifice and extraction of the endometriotic implants for histological examination. We found that the ERK pathway was significantly activated in endometriotic cells and in endometrial cells from patients with endometriosis compared to endometrial cells of control patients, both by ELISA and by western blot. This phenomenon was associated with an increased proliferation of endometriotic cells compared to endometrial cells. Treating endometriotic cells with A771726, PD98059 or U0126 abrogated the phosphorylation of ERK and significantly decreased the cellular proliferation in vitro. In vivo, A771726, leflunomide, PD98059, and U0126 controlled the growth of endometriotic implants in the mouse model of endometriosis. Our study shows that protein kinase inhibitors could be new candidates to treat endometriosis. However, further studies are needed to evaluate their effects and tolerability in humans.

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.
