CXCL11 and hepatocellular carcinoma: Compared to that of the control and si-NC groups, the migratory ability of HCC cells was significantly promoted in the CXCL11 + si-NC group but inhibited in the si-circUBAP2 group; the promotive effects of CXCL11 stimulation on HCC cell migration were significantly reversed by circUBAP2 silencing (Fig. 4B, C and Fig. S4A, B).
