However, Fig. 4 shows that the restoration of SPAG9 expression in miR-141-transfected cells significantly reversed the inhibitory effects of miR-141 on the migration and invasion of HCC cells, indicating that the SPAG9-JNK-MMP9 axis is also engaged in the anti-metastasis effect of miR-141 on HCC. The gene discussed is MMP9; the disease is hepatocellular carcinoma.
