LncRNA-H19 regulates cell proliferation and invasion of ectopic endometrium by targeting ITGB3 via modulating miR-124-3p. Exp Cell Res. 2019 May 11;: Authors: Liu S, Qiu J, Tang X, Cui H, Zhang Q, Yang Q Abstract Endometriosis, a common gynecological disease, is associated with pelvic pain and infertility. Endometriosis affects approximately 10% of women, but that number increases to 30-50% in symptomatic premenopausal women. Despite the prevalence of endometriosis, the cause has yet to be fully elucidated. Recent study of the molecular pathways of endometrial cancer has brought the long non-coding RNA (lncRNA) H19 to our attention. In this paper, we explored the role of lncRNA-H19 in endometrial tissue proliferation. We found that ectopic endometrial cells taken from women with endometriosis showed elevated levels of lncRNA-H19, with expression levels correlating to disease progression. Knockdown of H19 in ectopic endometrial cells inhibited cell proliferation and invasion. Coinciding with this change was an increase in microRNA-124-3p (miR-124-3p) and a decrease in integrin beta-3 (ITGB3) levels. The addition of a miR-124-3p inhibitor mitigated this decrease in ITGB3. Up-regulation of miR-124-3p markedly suppressed ITGB3 expression by binding to the 3' untranslated region (3' UTR), while inhibition of miR-124-3p had the opposite effect. ITGB3 overexpression potently counteracted the effects of miR-124-3p mimics on ectopic endometri...
