The packaging cells contain at least three vectors which collectively encode retroviral gag, pol, and env proteins, wherein the gag and pol genes are separated, in part, onto two or more different vectors. This is made possible by fusing Vpr or Vpx to pol proteins separated from gag so that the proteins are targeted to assembling virions. Among other advantages, the packaging cells provide the benefit of increased safety when used in human gene therapy by virtually eliminating the possibility of molecular recombination leading to production of replication-competant helper virus.

  • Publication number: 20040053210
    Abstract: This invention provides a method of converting a stem cell into a ventral neuron which comprises introducing into the stem cell a nucleic acid which expresses homeodomain transcription factor Nkx6.1 or Nkx6.2 protein in the stem cell so as to thereby convert the stem cell into the ventral neuron. Provided are methods of diagnosing a motor neuron degenerative disease in a subject. Also provides is a method of treating neuronal degeneration in a subjet which comprises implanting in diseased neural tissue of the subject a neural stem cell which is capable of expressing homeodomain Nkx6.1 or Nkx6.2 protein under conditions such that the stem cell is converted into a motor neuron after implantation, thereby treating neuronal degeneration in the subject.

  • Patent number: 6645766
    Abstract: The invention provides shuttle vectors, and methods of using shuttle vectors, capable of expression in, at least, a mammalian cell. Furthermore, the shuttle vectors are capable of replication in at least yeast, and optionally, bacterial cells. Also provided is a method wherein yeast are transformed with a shuttle vector as provided herein. Heterologous nucleic acids flanked by 5′ and 3′ ends identical to a homologous recombination site within the shuttle vector are introduced to the transformed yeast and allowed to homologously recombine with the shuttle vector such that they are inserted into the vector by the yeast organism. The shuttle vector is then recovered and transferred to a mammalian cell for expression.

  • Patent number: 6485966
    Abstract: A method for producing recombinant adeno-associated virus in the absence of contaminating helper virus or wild-type virus involves culturing a mammalian host cell containing an rAd/AAV hybrid virus, an AAV rep sequence and an AAV cap sequence under the control of regulatory sequences directing expression thereof. The rAd/AAV hybrid virus contains a rAAV construct to be packaged into an AAV virion in an backbone containing the adenoviral sequences necessary to express E1a and E1b gene products and to permit replication of the hybrid virus. The method of the invention permits replication of the hybrid virus and production of rAAV virion in this host cell in the absence of a helper virus and obviates a subsequent purification step to purify rAAV from contaminating virus.

  • Publication number: 20020119572
    Abstract: Methods and compositions for rendering proteins directly responsive to an external signal utilizing modulators that themselves respond to the external signal and are associated with the proteins. In response to the external signal, the modulator alters physical properties of the specific protein molecule(s) with which it is associated, thereby altering the structural and functional properties thereof. The modulator may, for example, transfer applied energy to a protein, or to a portion of the protein, thereby changing the protein structure and function.
