Beta thalassemia gene therapy using lentiviral vectors
Recent years, allogeneic bone marrow transplantation (BMT) has proved to be the successful cure for patients with thalassemia major, however this is restricted due to limited matched-related donor. Its complications include chronic graft-versus-host disease in 5-8% of patients. So, a molecular approach, such as gene therapy for direct normal beta globin gene transmission, seems quite promising ...
متن کاملInsertional gene activation by lentiviral and gammaretroviral vectors.
Gammaretroviral and lentiviral vectors are promising tools for gene therapy, but they can be oncogenic. The development of safer vectors depends on a quantitative assay for insertional mutagenesis. Here we report a rapid, inexpensive, and reproducible assay which uses a murine cell line to measure the frequency of interleukin-3 (IL-3)-independent mutants. Lentiviral and gammaretroviral vectors ...
متن کاملBarriers and recent advances in non-viral vectors targeting the lungs for cystic fibrosis gene therapy
Cystic fibrosis (CF) is an autosomal recessive disorder caused by mutations in CFTR genes that affect chloride ion channel. The CF is a good nominee for gene therapy as the asymptomatic carriers are phenotypically normal, and the desired cells are accessible for vector delivery. Gene therapy shows promising effects involving the correction of gene or replacement of the mutant gene with the func...
متن کاملHigh-fidelity gene targeting in embryonic stem cells by using sequence replacement vectors.
Mutations were targeted to the Hprt locus in murine embryonic stem cells by using sequence replacement vectors. When the vector was designed such that the mutated sequences were flanked on both sides by several kilobases of DNA homologous to the target locus, replacement of chromosomal sequences with the exogenous DNA occurred with precision. If, on the other hand, the target-homologous DNA on ...
متن کاملTargeting vectors for cancer gene therapy.
Establishment of a system that allows selective gene transfer to a tumor is expected to enable targeted therapy. Using a combination of fiber-modified adenovirus and antibody to a cell surface antigen, we have explored methods to enhance the selectivity of gene transfer. In addition, we aimed to establish a systematic screening method to search for antibody and cell surface target candidates fo...
