FGF5 and hepatocellular carcinoma: Fang et al30 reported that miR‐188‐5p suppresses tumour cell proliferation and metastasis by directly targeting FGF5 in hepatocellular carcinoma, implying that up‐regulated circMATR3 might sponge miR‐188‐5p and abolish its inhibitory effects on cell proliferation and metastasis.
