NUCLEIC ACID MOLECULES ENCODING CYTOPLASMATIC ALCOHOL DEHYDROGENASE AND GLUTAMIL-CYSTEIN SYNTHETASE, VECTORS TO INTRODUCE THEM AND PROCESSES EMPLOYING THESE VECTORS

摘要

This invention provides viral and retroviral vectors which comprises a nucleic acid molecule encoding a human cytosolic aldehyde dehydrogenase or a glutamylcysteine synthetase or combinations thereof. Further, this invention provides an isolated mammalian nucleic acid molecule encoding an cytosolic aldehyde dehydrogenase and glutamylcysteine synthetase.In addition, this invention provides a method for reducing the toxic effects of a cyclophosphamide in a subject which comprises replacing the subject's hematopoietic cells with hematopoietic cells of having the retroviral vector.Further, this invention provides a method for introducing a selectable marker into a mammalian cell which comprises transfecting the cell with a nucleic acid molecule encoding human cytosolic aldehyde dehydrogenase or glutamylcysteine synthetase.Lastly, this invention provides a method for selecting mammalian cells expressing protein of interest which comprises: a). introducing into the cells a nucleic acid molecule comprising a nucleic acid molecule encoding the protein of interest and the nucleic acid molecule encoding human cytosolic aldehyde dehydrogenase; b.) culturing the resulting transfected cells; and c.) selecting cells which express human cytosolic aldehyde dehydrogenase.
