MAPK1 and hepatocellular carcinoma: it was that MAPK1 negatively correlated with miR-584-5p expression in HCC tissues (Figure 6B), and the overexpression of miR-584-5p could significantly reduce the luciferase activity of MAPK1 WT, but had no effect on the luciferase activity of MAPK1 MUT (Figure 6C).
