We detected the methylation level of FARSB promoter in liver cancer tissues through the MethSurv website, and the correlation heat map showed that three methylation probes 16204618, cg03067828, and cg24484296 were in a hypermethylated state (Figure 4B) What’s more, the MethSurv analysis indicated that patients with high ZNF320 methylation had a worse overall survival than those with low ZNF320 methylation (p < 0.05) (Figure 4C–4E). The gene discussed is FARSB; the disease is liver cancer.
