HOXA10 DNA Methylation Level in the Endometrium Women with Endometriosis: A Systematic Review

Abstract

Endometriosis is an inflammatory chronic systemic disease resulting in pelvic pain and infertility. However, despite a high prevalence of endometriosis, disease identification is still insufficient, and a high percentage of misdiagnosing was observed. Hence, a comprehensive study needs to be done to improve our understanding of the pathogenesis of endometriosis. Aberrant hypermethylation of HOXA10 has been reported to play a role in endometriosis. Thus, a comprehensive literature search was conducted to identify the DNA methylation level of HOXA10 among endometriosis patients across populations. The literature search was done using PubMed, Scopus, EBSCOhost, and Science Direct applying (HOXA10 OR “homeobox A10” OR “HOXA-10” OR HOX1) AND (“DNA methylation” OR methylation) AND (endometriosis OR endometrioma) as keywords. From 491 retrieved studies, five original articles investigating the DNA methylation level of HOXA10 from endometrium tissues among endometriosis women were included. All five included studies were classified as high-quality studies. High HOXA10 DNA methylation level was observed in the endometrium tissue of women with endometriosis in all the included studies. The secretory phase was identified as the best sampling time for HOXA10 DNA methylation study in endometriosis, and the most studied DNA methylation site is the promoter region of the HOXA10. However, more studies are needed to expose the HOXA10 mechanism in the pathogenesis of endometriosis.

Gut Microbiota and Endometriosis: Exploring the Relationship and Therapeutic Implications

“…Another notion proposed in the 1920s and credited to Meyer suggests that celomatic metaplasia may be responsible for the development of endometriosis. It is postulated that endometriosis occurs as a result of metaplastic changes in the celomatic epithelium [30,31]. The underlying rationale of this notion is rooted in the shared embryological derivation of perineal (or serous) cells and endometrial cells.…”
