Our research found that multiple glycoproteins associated with cell adhesion were differentially expressed in ovarian epithelial cancer SKOV3 cells vs. non-cancerous ovarian epithelial IOSE80 cells, including VTN, VCAM1, ALCAM, CNTN5, PTK7, LAMC1, RGMB, THBS1, DSCAML1, PCDHA6, CD6, and UMOD (Supplementary Table S6-7), and participated in cell adhesion-related signaling pathways. Here, CD6 is linked to ovarian carcinoma.
