In the present study, functions and mechanisms of miR-182 and RELA in endometriosis were investigated. BAY 11-7082 was used to block NF-κB pathway. qRT-PCR, ELISA and western blot assays were employed to evaluate the expressions of miR-182 and RELA, inflammatory factors and epithelial–mesenchymal transition (EMT)-related markers, and activation of NF-κB pathway. MTT, wound healing or Transwell assays were used to evaluate the cell proliferation, migration and invasion capacities. Bioinformatic and dual-luciferase reporter assays were carried out to analyze the interaction between miR-182 and RELA. MiR-182 expression was decreased, while RELA was increased as developed from normal to eutopic and ectopic status, which was accompanied by upregulated inflammatory factors and EMT-related proteins. RELA was directly targeted by miR-182 in human endometrial stromal cells. Overexpression of RELA increased inflammation-associated and EMT-related markers expression, while miR-182 upregulation decreased the expression of these genes in a dose-dependent manner, which finally attenuated the proliferation, migration and invasion capacities of endometrial stromal cells through deactivation of NF-κB signaling pathway. Moreover, co-overexpression of RELA reversed the above effects induced by miR-182. In a word, miR-182 directly targeted RELA and inhibited proliferation, migration, invasion, EMT and inflammation of endometrial stromal cells through deactivation of NF-κB signaling pathway in endometriosis. These results provide new insights into the interaction between miR-182 and NF-κB pathway and their potential as therapeutic targets for treatment of endometriosis.\nSimilar content being viewed by others\nData Availability\nThe datasets used or analyzed during the current study are available from the corresponding author on reasonable request.\nReferences\nSchrager S, Falleroni J, Edgoose J (2013) Evaluation and treatment of endometriosis.
