Fig. 3. SPEN induces miR-4652-3p expression in NPC cells.
a Expression of miR-4652-3p were downregulated after knockdown of SPEN in HONE1 cells based on a miRNA array. b qRT-PCR detected miR-4652-3p expression in SPEN-silenced HONE1 cells compared with HONE1-NC group. *P < 0.05. c miR-4652-3p expression was remarkably upregulated after miR-4652-3p mimics infection in HONE1 and 5-8 F. ***P < 0.001. miR-4652-3p promoted cell migration and invasion in HONE1 and 5-8F cells examined by transwell, boyden (d) and wound-healing assay (e). *P < 0.05 (f) Representative bioluminescence images of the lungs after tail vein injection of cells. Lung metastases were confirmed by H&E staining. Scale bars, 200 μm. Arrows indicate nests of malignant cells.
