miR-342-3p suppresses NPC cell growth and invasion in vitro. a Real-time PCR analysis of miR-342-3p levels in NPC cells transfected with the miR-342-3p-expressing plasmid or vector. b Analysis of proliferation by MTT assay in NPC cells transfected with the miR-342-3p-expressing plasmid or vector. c Colony formation assay performed in NPC cells transfected with the miR-342-3p-expressing plasmid or vector. Left, representative images of colonies. d Transwell invasion assay. Ectopic expression of miR-342-3p significantly decreased the invasion of C666 and CN2 cells, compared to control cells. Column: mean of three independent experiments performed in three replicates. Error bar: SD. *P < 0.05
