Figure 2. The variation and DNA methylation of the KIF family in pan-cancer were investigated using multiple methods. (A) The alteration frequency of KIFs across different types of cancer was analyzed using cBioPortal. (B) Methylation differences between paired tumor and paracancer samples were examined; grey dots represent no statistical significance. (C) Copy number variation (CNV) of KIFs in cancers was assessed by GSCA. (D) The correlation between DNA methylation and mRNA expression of KIFs was determined using TCGA data.
