Abstract

Objectives To detect specific mitochondrial proteins in eutopic endometrial samples from women with and without endometriosis and to build diagnostic models.Design Eutopic endometrial samples from women with endometriosis (excluding adenomyosis) and women with benign indications as control were studied by using surface-enhanced laser desorption/ionization time-of-flight mass spectrometry protein-chip technology. After finding the biomarkers, the diagnostic model was evaluated and validated by leave-one cross-validation.Setting Collaborative investigation in an academic research environment.Patient(s) Twenty-four patients with endometriosis (excluding adenomyosis) and 29 patients with benign indications as control.Intervention(s) Surgical excision of eutopic endometrial biopsy of patients with endometriosis and controls.Main outcome measure(s) Mitochondrial protein expression.Result(s) Seventy-eight qualified mitochondrial protein peaks were detected, ten of them had a significant difference. Three combined potential biomarkers, with mass-to-charge ratios (m/z) of 15,334, 15,128, and 16,069, were found, and the diagnostic system distinguished endometriosis from control samples with a specificity of 86.2% and a sensitivity of 87.5%.Conclusion(s) We discovered potential mitochondrial biomarkers of eutopic endometrium in endometriosis and set up a diagnostic model. Further identification of the proteins we found will help to explain pathology, new diagnoses, and therapeutic approaches for endometriosis.

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

  • Menstrual cycle phase of endometrial samples was not specified in several of the studies.

    “Specifically, menstrual cycle phase of endometrial samples was not specified in several of the studies [132, 135], and only one randomly divided endometrial samples into training and test sets [131].”

  • In the largest study to date involving a total of 53 endometrial samples, a panel of three differentially expressed peptide peaks (16.069 m/z, 15.334 m/z, and 15.128 m/z) diagnosed endometriosis (all rAFS stages) with 87.5% sensitivity and 86.2% specificity.

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.
