BACKGROUND: Thyroid cancer (TC) is a frequent endocrine malignant tumor with various pathologic types. miRNA-363-3p plays a pivotal part in the occurrence, development, prognosis, and treatment of cancer.
OBJECTIVE: To explore the mechanism of miRNA-363-3p in TC and provide a new idea for targeted therapy of TC.
METHODS: Differential miRNAs and downstream target mRNAs in TC tissues were predicted with bioinformatics analysis. Expression levels of miRNA-363-3p and Synaptotagmin I (SYT1) in TC cells were ascertained by qRT-PCR. Cell migration, invasion, and proliferation were detected by wound healing assay, transwell assay, colony formation assay, CCK-8, and BrdU fluorescence experiment, respectively. Flow cytometry was utilized to detect the levels of apoptosis and necrosis. Immunofluorescence assay was used for detecting autophagosome formation in cells, and the expression levels of autophagy-related proteins, as well as NF-κB related proteins, were measured by western blot. Dual-luciferase reporter gene assay was applied for detecting the interaction between miRNA-363-3p and SYT1.
RESULTS: miRNA-363-3p was prominently down-regulated in TC cells. miRNA-363-3p overexpression suppressed migration, invasion, and proliferation, promoting apoptosis and necrosis of TC cells. As the downstream target of miRNA-363-3p, SYT1 was up-regulated in TC cells. SYT1 overexpression reversed the inhibition of TC cell proliferation, invasion, migration, and autophagy mediated by miRNA-363-3p overexpression. In addition, miRNA-363-3p overexpression inhibited the activation of the NF-κB pathway in cells, while further overexpression of SYT1 weakened the inhibition of miRNA-363-3p overexpression on the NF-κB pathway.
CONCLUSION: miRNA-363-3p affected the NF-κB signaling pathway by down-regulating SYT1 expression to inhibit the malignant progression of TC cells, providing theoretical support for the treatment of TC.
