摘要：Neurofibromatosis type I (NF1) is a carcinoma mainly featured by malignant peripheral nerve sheath tumor (MPNST). Dysregulated microRNAs (miRNAs) play decisive roles in tumor initiation and development. Our study sought for the possible roles of miR-612 in NF1. RT-qPCR estimated the expression of nuclear factor kappa B subunit 1 (NFKB1), miR-612, and Fas apoptotic inhibitory molecule 2 (FAIM2) in NF1, separately. Cell proliferation and migration were detected by CCK-8 and transwell experiments. Cell apoptosis was measured via flow cytometry and detection of the expression and activity of caspase 3/8/9. Luciferase reporter, ChIP, and RIP assays testified the interplay between studied genes. Rescue and in vivo assays affirmed the whole mechanism of miR-612 in NF1. We indicated that miR-612 was significantly low in tumor tissues and cells. Mechanism experiments confirmed that miR-612 promotion repressed cell proliferation and migration, and induced cell apoptosis. Besides, NFKB1-regulated miR-612 targeted FAIM2. Spearman's correlation analysis validated the correlation between each two genes. Finally, rescue and in vivo assays affirmed that miR-612 targeted FAIM2 to regulate cellular activities of NF1. The current investigation uncovered the molecular mechanism underlying miR-612 in NF1, establishing miR-612 as a novel therapeutic target for the treatment of NF1 patients.
