To explore whether GNA14 affects HCC function, we used lentivirus to stably overexpress GNA14 in SK-Hep-1 and Hep3B cells with low GNA14 expression, and siRNA to inhibit GNA14 in HCCLM3 and Huh7 cells with high GNA14 expression (Figure 5A-B and Figure S3A). The gene discussed is GNA14; the disease is hepatocellular carcinoma.
