    摘要: Novel cationic amphiphiles are provided that facilitate transport of biologically active (therapeutic) molecules into cells. The amphiphiles contain lipophilic groups derived from steroids, from mono or dialkylamines, or from alkyl or acyl groups; and cationic groups, protonatable at physiological pH, derived from amines, alkylamines or polyalkylamines. There are provided also therapeutic compositions prepared typically by contacting a dispersion of one or more cationic amphiphiles with the therapeutic molecules. Therapeutic molecules that can be delivered into cells according to the practice of the invention include DNA, RNA, and polypeptides. Representative uses of the therapeutic compositions of the invention include providing gene therapy, and delivery of antisense polynucleotides or biologically active polypeptides to cells. With respect to therapeutic compositions for gene therapy, the DNA is provided typically in the form of a plasmid for complexing with the cationic amphiphile. Novel and highly effective plasmid constructs are also disclosed, including those that are particularly effective at providing gene therapy for clinical conditions complicated by inflammation. Additionally, targeting of organs for gene therapy by intravenous administration of therapeutic compositions is described.

    摘要: The invention is directed to a transgene expression system comprising a transcription unit which contains a transgene operably linked to expression control sequences, preferably the CMV promoter, and which is delivered simultaneously with all or part of the adenovirus E4 genomic region to a cell in order to facilitate persistent expression of the transgene. The components of the transgene expression system can be delivered by vectors including plasmids and/or viruses and may be complexed with cationic amphiphiles to facilitate entry into a cell. The invention is also directed to methods for the production of the transgene expression system. The invention is further directed to compositions that contain the transgene expression system and to methods for the use of such compositions to deliver transgenes encoding biologically active proteins to cells.
