摘      要：MicroRNA(miR)-200b-3p has been associated with many tumors,but its involvement in pituitary adenoma is *** study investigated the molecular mechanism underlying miR-200b-3p regulation in pituitary adenomas to provide a theoretical basis for *** was used to analyze pituitary adenoma-related genes and screen new targets related to RECK and *** well,the relationship between miR-200b-3p and RECK protein was verified using a double-luciferase reporter gene *** expression of miR-200b-3p in clinical samples was analyzed by in situ *** of the miR-200b-3p inhibitor and small interfering-RECK(si-RECK)was verified by ***3 cell viability and proliferation were detected using CCK8 and EdU *** was detected by flow cytometry and western *** healing and Transwell assays were used to detect cell migration and *** effects of miR-200b-3p and RECK on GH3 cells were verified using salvage ***-200b-3p was highly expressed in pituitary tumor *** of miR-200b-3p inhibited cell proliferation promoted cell apoptosis,inhibited invasion and migration,and inhibited the expression of matrix ***,miR-200b-3p negatively regulated *** expression of RECK in pituitary adenoma tissues was lower than that in neighboring ***-RECK rescued the function of miR-200b-3p inhibitors in the above cellular behaviors,and miR-200b-3p accelerated the development of pituitary adenoma by negatively regulating RECK *** summary,this study investigated the molecular mechanism by which miR-200b-3p regulates the progression of pituitary adenoma through the negative regulation of *** findings provide a new target for the treatment of pituitary adenoma.
