Abstract:

The present invention relates to transgene expression systems, related compositions comprising the transgene expression systems, and methods of making and using them. Preferred systems employ an adenovirus transgene expression vector comprising DNA encoding a transgene which codes for a desired product operably linked to expression control sequence, and at least a portion of the adenovirus E3 region and certain portions of the E4 region. The E4 portions comprise the open reading frame sequence known as E40RF3 and at least one other portion of E4. Preferably the E4 portion of the vector (or âE4 cassetteâ) includes E40RF3 and at least one other portion selected from E40RF4, E40RF6/7 and E40RF3/4. The invention has a number of important features including improving persistency of transgene expression in a desired host cell. The transgene expression systems of the present invention are useful for a variety of applications including providing persistent cellular expression of the transgene in vitro and in vivo.

Abstract:

The present invention provides recombinant nucleic acid molecules encoding a chimeric transactivator protein including a DNA binding domain of a DNA binding protein and a protein domain capable of transcriptional activation. The present invention also provides recombinant viral and non-viral vectors that are able to infect and/or transfect and sustain expression of a biologically active chimeric transactivator proteins in mammalian cells. Also provided are host cell lines and non-human transgenic animals capable of expressing biologically active chimeric transactivator proteins. In another aspect, compositions and methods for treating or preventing ischemic damage associated with hypoxia-related disorders are provided.

US Classification:

4353201, 536 231

Abstract:

Disclosed are full length isolated DNAs encoding cystic fibrosis transmembrane conductance regulator (CFTR) protein and a variety of mutants thereof. Also disclosed are antibodies specific for various CFTR domains and methods for their production. Expression of CFTR from cells transformed with these CFTR genes or cDNAs demonstrate surprising CFTR intracellular distributions and results thereby providing for new diagnostic and therapeutic procedures.

International Classification:

C12N015/861
C12N007/01

US Classification:

435/456000, 435/235100, 435/320100

Abstract:

This invention provides a recombinant adenovirus expression vector characterized by the partial or total deletion of the adenoviral protein IX DNA and having a gene encoding a foreign protein or a functional fragment or mutant thereof. Transformed host cells and a method of producing recombinant proteins and gene therapy also are included within the scope of this invention. Thus, for example, the adenoviral vector of this invention can contain a foreign gene for the expression of a protein effective in regulating the cell cycle, such as p53, Rb, or mitosin, or in inducing cell death, such as the conditional suicide gene thymidine kinase. (The latter must be used in conjunction with a thymidine kinase metabolite in order to be effective).
