Four proteins (KRT14, Hornerin [HRNR], Cell Division Cycle Associated 8 [CDCA8], and Fibronectin Type III Domain Containing 3B [FNDC3B]) were identified as unique to all patient HGSC cells at the cancer–mesothelial interface following this high-stringency approach (Figure 2C–E). This evidence concerns the gene CDCA8 and cancer.
