Although desmocollins have an important position in cancer-related research, there are little reports about the relations between cancers and desmocollin 1 (DSC1). The present study was designed to investigate the correlations between DSC1 and head and neck squamous cell carcinoma (HNSCC). First we analyzed the GEO database; then, HNSCC and pericarcinous tissues were collected to verify the results. DSC1 expression was detected by western blot and real-time PCR. The co-expression genes of DSC1 were extracted from Cancer Cell Line Encyclopedia database (CCLE database), and their correlation was analyzed in The Cancer Genome Atlas HNSCC database (TCGA HNSCC database). Next the gene ontology analysis (GO) was carried out. Moreover, we suppressed DSC1 in FaDu cell to investigate the internal mechanism. GEO database showed that DSC1 was higher in HNSCC and patients with higher DSC1 had unfavorable prognosis. The results of the samples showed that DSC1 was significantly higher in HNSCC than in normal tissue, which was consistent with the results of GEO database. The co-expression genes of DSC1 were extracted from CCLE database and verified in TCGA HNSCC database. It revealed that DSC1 was related to cell signal transduction. In FaDu/siDSC1 cells, the proliferation and migration were decreased compared to FaDu cells, and the expression levels of beta-catenin, c-myc and cyclin D1 down-regulated significantly. The increased expression of DSC1 can promote the occurrence of HNSCC and is associated with tumor. The increased expression of DSC1 also indicates a poor prognosis of the patients with HNSCC.
