DSC2 and oral cavity squamous cell carcinoma: We noticed that two relevant genes: DSC2 (encoding desmocollin 2, involved in cell adhesion, GO:0007155), and KRT17 (encoding keratin 17, involved in morphogenesis of an epithelium, GO:0002009; signal transduction GO:0007165; epidermis development, GO:0008544; positive regulation of cell growth, GO:0030307) are highly expressed in oral squamous cell carcinoma cell line, while they are down regulated in specimens from patients with lymph node involvement.
