Retroviral vector capable of transducing the aldehyde dehydrogenase-1 gene and uses of said vector

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 a cytosolic aldehyde dehydrogenase and glutamylecysteine 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 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 dehdrogenase: b) culturing the resulting transfected cells; and c) selecting cells which express human cytosolic aldehyde dehdrogenase.
