To identify genes that could potentially serve as molecular therapeutic markers for human head and neck cancer (HNC),DSG3 is identified overexpressed in HNC, with the degree of overexpression associated with clinicopathologic features of the tumor. Inhibition of DSG3 significantly suppresses carcinogenic potential in cellular and in vivo animal studies. DSG3 is a potential molecular target in the development of adjuvant therapy for HNC. DSG3 Protein, Mouse, Recombinant (His) is expressed in HEK293 mammalian cells with C-His tag. The predicted molecular weight is 64.3 kDa and the accession number is O35902-1.
