title: Dermokine: an extensively differentially spliced gene expressed in epithelial cells.
abstract: Studies performed to discover genes overexpressed in inflammatory diseases identified dermokine as being upregulated in such disease conditions. Dermokine is a gene that was first observed as expressed in the differentiated layers of skin. Its two major isoforms, alpha and beta, are transcribed from different promoters of the same locus, with the alpha isoform representing the C terminus of the beta isoform. Recently, additional transcript variants have been identified. Extensive in silico analysis and reverse transcriptase (RT)-PCR cloning has confirmed the existence of these variants in human cells and tissues, identified a new human isoform as well as the gamma isoform in mouse. Recombinant expression and analysis of the C-terminal truncated isoform indicate that the molecule is O-linked glycosylated and forms multimers in solution. In situ hybridization and immunohistochemistry has shown that the gene is differentially expressed in various cells and tissues, other than the skin. These results show that the dermokine gene is expressed in epithelial tissues other than the skin and this expression is transcriptionally and posttranscriptionally complex.
