Current Gene Therapy - Volume 6, Issue 4, 2006

It is feasible to restrict transgene expression to a tissue or region in need of therapy by using promoters that respond to focusable physical stimuli. The most extensively investigated promoters of this type are radiation-inducible promoters and heat shock protein gene promoters that can be activated by directed, transient heat. Temporal regulation of transgenes can be achieved by various two- or three-component gene swit Read More

Lung transplantation is effective life-saving therapy for the treatment of a variety of end-stage lung diseases. However, the application of lung transplantation is hindered by multiple factors such as the shortage of organ donors, early graft failure and chronic graft dysfunction. These problems are related to various lung injuries before and after transplantation including donor brain-death-related lung injury, ischemia, r Read More

The use of multiple peptide motifs to provide effective gene delivery holds great promise as an elegant, nonimmunogenic approach to gene therapy. The molecular understanding of cell and viral biology provides a strong foundation on which to pursue this objective. Synthetic peptides containing multiple lysines and/or arginines (occasionally ornithines) provide natural polycations for multivalent electrostatic binding of D Read More

As a novel form of molecular medicine based on direct actions over the genes, targeted gene repair has raised consideration recently above classical gene therapy strategies based on genetic augmentation or complementation. Targeted gene repair relies on the local induction of the cell's endogenous DNA repair mechanisms to attain a therapeutic gene conversion event within the genome of the diseased cell. Succes Read More

The advent of sophisticated experimental tools that can probe the molecular pathology of cancer has revealed a number of genes and gene families that could prove attractive targets for cancer therapy. Thus, gene silencing strategies have been envisioned to treat cancer by targeting the cancer cell's capacity to: (I) resist conventional treatment methods (chemotherapy and radiotherapy), (II) promote angiogenesis, an Read More

Transgenic animals are of outstanding relevance for medical sciences, because they can be used to model human diseases and to develop gene therapy strategies. A recent development is lentiviral transgenesis: The generation of transgenic animals by lentiviral transduction of oocytes or early embryos. Lentiviral transgenesis is an efficient method to express transgenes in mice and rats as well as in biomedically relevant li Read More
