Therefore, 17 genes (PRKCA, HRAS, TLN1, MAP2K1, PPP1CC, PTEN, AKT1, VEGFB, MAPK1, IGF1R, CCND1, ARHGAP5, BCL2, RAC1, PPP1R12A, RAP1A, RAP1B) of upregulated miRNAs and 21 genes (PIK3CG, CAV2, FLT1, ROCK1, MET, IGF1, ITGA3, HGF, KDR, AKT1, MAPK1, CRKL, PAK4, BCL2, VEGFA, MAPK9, MAPK8, CRK, PIK3R1, AKT2, PIK3R2) of downregulated miRNAs which are involved in focal adhesion may interact with the selected 6 miRNAs, thereby modulating invasion and metastasis in HCC. This evidence concerns the gene PIK3R2 and hepatocellular carcinoma.
