In the case of CNS demyelinating disease, K6 expression in CNS occurs additionally in perivascular and parenchymal inflammatory cells suggesting a role in pathogenesis. Herein we describe two unique transcripts that occur within the human and mouse K6 genes that differ in their 5\u2032\u2010untranslated regions. These transcripts have identical translation initiation sites in exon 3, are expressed in a tissue\u2010specific fashion and are differentially regulated in response to CNS injury. While the human and mouse 5\u2032\u2010transcripts differ in sequence they are identical in genomic organization and tissue\u2010specific expression. The most 5\u2032\u2010transcript, designated transcript 1, includes exon 1\u20137, and was detectable in all CNS regions, but not in any non\u2010CNS tissues examined (spleen, thymus, liver, kidney, pancreas, submandibular gland and peripheral nerve). In contrast, transcript 2 lacks exon 1, but contains a unique sequence at the 5\u2032\u2010end of exon 2, designated exon 2A. Transcript 2 was expressed both in CNS and in each peripheral tissue. In a murine model of human CNS demyelinating inflammatory disease induced by Theiler's picornovirus, mouse K6 transcript 1 was up\u2010regulated in brain and spinal cord at acute and more chronic phases of CNS inflammation and demyelination, while overall transcript 2 expression was not significantly altered. However, in isolated splenocyte cultures, transcript 2 was up\u2010regulated two\u2010fold by cellular activation. Tissue\u2010specific expression patterns and differential regulation in CNS disease indicates that each K6 5\u2032\u2010transcript is probably regulated by unique promoter elements and may serve as a molecular target to treat inflammatory demyelinating disease.<\/jats:p>","DOI":"10.1111\/j.1471-4159.2004.02826.x","type":"journal-article","created":{"date-parts":[[2004,12,2]],"date-time":"2004-12-02T14:41:32Z","timestamp":1101998492000},"page":"1439-1449","source":"Crossref","is-referenced-by-count":45,"title":["Distinct promoters regulate tissue\u2010specific and differential expression of kallikrein 6 in CNS demyelinating disease"],"prefix":"10.1111","volume":"91","author":[{"given":"G.
