TRAF5 and hepatocellular carcinoma: To further explore whether DDX11-AS1 affected the growth and metastasis of HCC cells through modulating the miR-34a-3p/TRAF5 axis, RT-qPCR and Western blot analysis were tested to find reduced TRAF5 expression after co-transfection of restored DDX11-AS1 and miR-34a-3p, or that of elevated DDX11-AS1 and silenced TRAF5 (Figs. 7a-c; 9a-c).
