Mouse epiblast stem cells (EpiSCs) can be derived from a wide range of developmental stages. To characterize and compare EpiSCs with different origins, we derived a series of EpiSC lines from pregastrula stage to late-bud-stage mouse embryos. We found that the transcriptomes of these cells are hierarchically distinct from those of the embryonic stem cells,(More)
To date, over 1800 gene therapy clinical trials have been completed, are ongoing or have been approved worldwide. Our database brings together global information on gene therapy clinical trials from official agency sources, published literature, conference presentations and posters kindly provided to us by individual investigators or trial sponsors.

None of the vector systems currently available for gene therapy applications have been shown to be capable of both efficient gene transfer into nondividing cells and long-term expression through stable integration into host cell DNA. While integrating vectors based on adeno-associated virus are capable of mediating gene transfer into nondividing cells, this(More)
BACKGROUND Recessive LPIN1 mutations were identified as a cause of severe rhabdomyolysis in pediatric patients. The human lipin family includes two other closely related members, lipin-2 and 3, which share strong homology and similar activity. The study aimed to determine the involvement of the LPIN family genes in a cohort of pediatric and adult patients(More)
X-linked Severe Combined Immunodeficiency (SCID-X1) is a genetic disease that leaves newborns at high risk of serious infection and a predicted life span of less than 1 year in the absence of a matched bone marrow donor. The disease pathogenesis is due to mutations in the gene encoding the Interleukin-2 receptor gamma chain (IL-2Rγ), leading to a lack of(More)
Recombinant adeno-associated virus (rAAV) shows significant promise as a vector for gene transfer in pre-clinical models of human disease, and is currently being evaluated in human clinical trials. As a consequence, increasing attention is being turned to the important tasks of optimizing rAAV titer, purity, and stability. We have observed dramatic(More)
Neurofibromatosis type 1 (NF1) is a common genetic condition caused by mutations in the NF1 gene. Patients often suffer from tissue-specific lesions associated with local double-inactivation of NF1. In this study, we generated a novel fracture model to investigate the mechanism underlying congenital pseudarthrosis of the tibia (CPT) associated with NF1. We(More)
The estrogen receptor (ER)-positive human breast cancer cell line T 47D exhibited genetic instability under cell culture conditions which maintained almost continuous exponential growth. This resulted in the spontaneous generation of three ER-positive sublines with a range of DNA ploidies and distinctive phenotypes. One of these sublines, T 47D-5, exhibited(More)
The potential of adeno-associated virus (AAV) vectors for gene transfer and gene therapy applications is currently being intensively investigated. Although much progress has been made in defining AAV vector biology, inconsistencies remain in the literature regarding the efficiency of AAV transduction in various cell types. In the course of exploring these(More)
Modification of electrical conduction would be a useful principle to recruit in preventing or treating certain arrhythmias, notably ventricular tachycardia (VT). Here we pursue a novel gene transfer approach to modulate electrical conduction by reducing gap junctional intercellular communication (GJIC) and hence potentially modify the arrhythmia substrate.(More)
