Cardiac-Specific Gene Expression Facilitated by an Enhanced Myosin Light Chain Promoter

Abstract excerpt

BACKGROUND: Adenoviral gene transfer has been shown to be effective in cardiac myocytes in vitro and in vivo. A major limitation of myocardial gene therapy is the extracardiac transgene expression. METHODS: To minimize extracardiac gene expression, we have constructed a tissue-specific promoter for cardiac gene transfer, namely, the 250-bp fragment of the myosin light chain-2v (MLC-2v) gene, which is known to be...
