Description:
Experiments were performed to determine if retroviral-mediated transfer of the human multidrug resistance 1 gene (MDR1) into murine bone marrow cells would confer drug resistance to the cells and whether the MDR1 gene could be used as a dominant selectable marker in vivo. When mice transplanted with bone marrow cells containing a transferred MDR1 gene were treated with the cytotoxic drug taxol, a substantial enrichment for transduced bone marrow cells was observed. This demonstration of positive selection establishes the ability to amplify clones of transduced hematopoietic cells in vivo and suggests possible applications in human therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sorrentino, B P -- Brandt, S J -- Bodine, D -- Gottesman, M -- Pastan, I -- Cline, A -- Nienhuis, A W -- New York, N.Y. -- Science. 1992 Jul 3;257(5066):99-103.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Clinical Hematology Branch, National Heart, Lung, and Blood Institute, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1352414" target="_blank"〉PubMed〈/a〉
