To further verify the target relationship between miR-30b-3p and TRIM27, miR-30b-3p mimics or miRNA NC mimics were transfected into the HCC cells, and the RT-qPCR results showed that miR-30b-3p substantially reduced the mRNA level of endogenous TRIM27 compared with the control group (Figure 3D). The gene discussed is TRIM27; the disease is hepatocellular carcinoma.
