| 摘要 |
The present invention concerns a method of modulating one or more cellular activities dependent on a POD nuclear structure in a host cell through the action of a molecule of adenoviral origin, wherein said molecule of adenoviral origin is capable of interacting with the cellular function of said POD nuclear structure. In a first aspect, the present invention provides a method, a replication-defective adenoviral vector and a composition intended to reduce or inhibit one or more POD-dependent cellular activities by introducing said adenoviral molecule in the host cell. The invention also relates to the use of such a replication-defective adenoviral vector or molecule to provide a reduction or an inhibition of the antiviral or apoptosis cellular activities as well as to provide a reduction of the toxicity induced by a replication-defective adenovirus vector or to enhance transgene expression driven from said replication­defective adenovirus vector. In a second aspect, the present invention provides a replication-competent adenoviral vector having the native pIX or E4orf3 gene non­functional or deleted, as well as a viral particle, a host cell and a composition comprising such a replication-competent adenoviral vector and a method of treatment using such a replication-competent adenoviral vector. The present invention also concerns a method of enhancing apoptosis in a host cell using such a replication-competent adenoviral vector. |
