To further understand the effect of miR-574-5p on regulating the tumor progression of human lung cancer cells, we predicted the targets of miR-574-5p by prediction programs including TargetScan and Miranda, and selected 10 possible target including CALCOCO1, RFX4, CD96, CHEX1, FOXI2, DGKG, ZNF589, ZDHHC14, CCDC88C, CLVS1 for real time PCR analysis. Here, RFX4 is linked to neoplasm.
