Subsequently, we analyzed the G6PD gene expression in WRL68, LI-7, SNU-398, SNU-449, SK-HEP-1 cells, and showed that compared with normal liver cells, the G6PD expression level of liver cancer cells was significantly increased, and the expression level of LI-7 and SNU-449 was the highest (Fig. 2D). The gene discussed is G6PD; the disease is liver cancer.
