The proliferation, migration, and invasion abilities of HCC cells were suppressed, while the apoptosis rate was elevated after co-transfection of pcDDX11-AS1 and miR-34a-3p mimic, or that of pcDDX11-AS1 and sh-TRAF5 (Figs. 7d-F; 8a, b; 9d-f; 10a, b). Here, TRAF5 is linked to hepatocellular carcinoma.
