The correlation between CHMP7 and cancer stemness was analyzed based on six tumor stemness indices calculated by mRNA expression and methylation signature, which were significantly positively correlated in HNSC and negatively correlated in LUAD, COAD, COADREAD, BRCA, THYM, PCPG, and BLCA (Figure 5B; Supplementary Material S2). This evidence concerns the gene CHMP7 and neoplasm.
