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. The gene discussed is RAP1A; the disease is hepatocellular carcinoma.
