Other studies indicate that the regulatory functions of individual C19MC miRNAs in cancer are related to silencing the expression of factors and signaling pathways related to adhesion, migration, differentiation, growth and angiogenesis (Rap1b, ABCG2, DAPK2, ephrins-EphB2 and EphB4, CXCR4) [98,99,100,114,115,116,117]. Here, RAP1B is linked to cancer.
