Abstract

To study the regulation of microRNA 199a (miR-199a) on adhesion, migration and invasion ability of human eutopic endometrial stromal cells (ESC) from patients with endometriosis. ESC were transfected with miR-199a mimics or negative control (NC) RNA by lipofectamine 2000. The adhesion, migration and invasion ability of ESC were detected by cell adhesion assay, scratch assay, cell migration assay and matrigel invasion assay, respectively. Luciferase reporter assay was used to evaluate whether IKKβ was the target gene of miR-199a. The expression of ikappa B kinase beta (IKKβ), inhibitory kappa B alpha (IκB-α), phospho-IκB-α(p-IκB-α) and nuclear factor-kappa B (NF-κB) protein were measured by western blot. (1) Adhesion potential: the adhesion inhibitory rates were (14 ± 4)% in miR-199a group and 0 in control group, which showed significant difference (P < 0.01). (2) Migration and invasion: in the scratch assay, ESC transfected with miR-199a exhibited a lower scratch closure rate than that of controls. In migration and invasion assays, the migration and invasion ability of miR-199a group were significantly decreased compared with those of NC group [130 ± 31 vs. 247 ± 36 (P < 0.01); 63 ± 15 vs. 133 ± 17 (P < 0.01), respectively].

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
