Chimeric promoters for controlling expression in muscle cells

摘要

The present invention concerns chimeric constructs comprising a skeletal alpha-actin gene promoter operably linked with at least a skeletal muscle-specific enhancer of a human gene. It also provides an expression cassette comprising such a chimeric construct to control expression of a gene of interest. The invention also relates to a vector, a viral particle, an eukaryotic host cell, a pharmaceutical composition comprising said expression cassette and their use for specific expression in skeletal muscle cells as well as for therapeutic or prophylactic purposes. Finally, the present invention also provides the therapeutic use of an expression cassette, a vector and a viral particle comprising a gene of interest placed under the control of a skeletal alpha-actin gene promoter and a muscle-specific enhancer, especially for treating peripheral ischemia.
