To identify the role of SOX2-OT in HCC cells, HepG2 and Huh7 cells with relatively high expression were selected according to the results in Figure 1C, and the SOX2-OT expression was inhibited by transfection of SOX2-OT siRNA, and the si-NC transfection was used as the control. The gene discussed is OXT; the disease is hepatocellular carcinoma.
