These 11 genes were GALNT5, COL8A1, FZD1, CCN4, ZEB1, ZCCHC24, CLMP, LUM, FBN1, ITGA11, and ZNF469. To understand whether the expression of 11 genes was associated with the immune infiltration, we performed the Pearson correlation analysis between their expression and the immune score in OC as well as other 32 cancer types (Supplementary Figure S5). Here, CCN4 is linked to cancer.
