title: [Gene transfer as treatment for metabolic inherited liver diseases]
abstract: OBJECTIVE: To study gene transfer looking for its future clinical application in the treatment of metabolic inherited liver diseases. METHODS: Bibliographic review about the subject. RESULTS AND CONCLUSIONS: Gene transfer into the liver would be an alternative to liver transplantation to treat some inherited metabolic diseases. Various vectors have been employed for gene transfer, including retrovirus vectors, whose integration into the chromosomal DNA would allow stable long term expression of the transgene. The integration of retrovirus vectors into the genoma of the target cell is only possible during mitosis. Therefore, these vectors must be delivered during hepatic regeneration induced by partial hepatectomy, for example. Another obstacle to be overcome is the extra hepatic dissemination of retrovirus, in particular to the germinals cells, due to the risk of changing the genetical heritage of the progeniture.
