Adenovirus as an expression vector in muscle cells in vivo.

Attempting gene transfer in muscle raises difficult problems: the nuclei of mature muscle fibers do not undergo division, thus excluding strategies involving replicative integration of exogenous DNA. As adenovirus has been reported to be an efficient vector for the transfer of an enzyme encoding gene in mice, we decided to explore its potential for muscle cells. Advantages of adenovirus vectors are their independence of host cell replication, broad host range, and potential capacity for large foreign DNA inserts.
