Aberrant methylation at HOXA10 may be responsible for its aberrant expression in the endometrium of patients with endometriosis
Abstract
Objective HOXA10, expressed in endometrium, plays an important role in uterine receptivity at the time of implantation. In the endometrium of women with endometriosis, its expression is reduced. The aim of this study was to determine whether the observed aberrant expression of HOXA10 is caused by aberrant methylation of the gene.Study design Endometrial tissues were collected from 6 women with laparoscopically confirmed endometriosis, and 4 women who underwent tubal ligation and were confirmed to have no endometriosis. In addition, menstrual blood from 5 women with no gynecologic complaints was collected and also used as controls. Methylation-specific polymerase chain reaction (PCR) and bisulfite sequencing were performed in 3 fragments in 2 regions of HOXA10 to detect difference in methylation patterns. Real-time reverse transcriptase (RT)-PCR was also performed to measure expression levels of HOXA10 in select cases and controls.Results In all 3 fragments, there were highly statistically significant differences in methylation patterns between women with endometriosis and those without endometriosis. The expression level of HOXA10 was lower in women with endometriosis than those without, as previously reported.Conclusion There is aberrant methylation in the endometrium of women with endometriosis compared with those without endometriosis. The aberrant methylation at HOXA10 may be responsible for the aberrant gene expression in the endometrium of women with endometriosis. This finding suggests that endometriosis may also be an epigenetic disease.

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.
