JMJD8 and pancreatic adenocarcinoma: Figure 4E presents the list of the top 8 CTL-correlated cancer subtypes; JMJD8 promoter methylation was positively correlated with CTL infiltration in BRCA, PAAD, and MESO. Figure 4F exhibits the correlation scatter plots and the Kaplan–Meier curves, demonstrating that JMJD8 promoter methylation was associated with CTL infiltration and predicted more prolonged survival in three BRCA subtypes and MESO.
