CD44 and acute myeloid leukemia: Figure 5I illustrates that the trends of antigen expression levels were consistent in the TCGA and Beat AML cohorts. Notably, among the antigens with statistically expression differences in both cohorts, CD117, CD44, CD244, CD96, WT, and TERT exhibited higher expression levels in G2 compared to G1; while CLEC12A, Folate receptor β, IL1RAP, and TIM3 showed higher expression levels in G1 compared to G2. It should be mentioned that in Figure 5I, the expression levels of CD44 were presented instead of CD44v6.
