摘要:
The present invention provides recombinant nucleic acid expression cassetie and helper dependent adenovirus, where the expression cassettes utilize a miRNA based system for controlling expression of nucleases in helper dependent adenoviral viral producer cells, thus permitting production and use for in in vivo gene editing in CD34+ cells.
摘要:
A combination of retroviral and adenoviral vectors are used for high efficiency gene transfer into hepatocytes, resulting in long term gene expression. Hepatocytes are transduced in vivo with a recombinant adenovirus vector that expresses a molecule capable of inducing hepatocyte regeneration, such as urokinase plasminogen activator (uPA) or tissue plasminogen activator (tPA), resulting in a high rate of liver regeneration. During the regenerative phase, ex vivo or in vivo retroviral-mediated gene transfer into hepatocytes results in greater transduction efficiencies. The compositions and methods thus provide new means for gene therapy, and transgenic non-human animals useful in developing new therapeutic and preventative agents. The vectors can be used for high efficiency transduction of ribozymes specific for hepatitis C virus RNA.
