Technology Overview:
Two nucleoside transport-deficient cell lines were developed through isolation from a hypoxanthine-guanine phosphoribosyltransferase-deficient derivative of wild type CEM cells (a human T lymphoblast cell line originally derived from a patient with acute lymphocytic leukemia). The Ara-C/8C and TUB-4D clones were isolated by virtue of their resistance to 8 µM arabinosylcytosine and 4µM tubercidin, respectively. One cell line completely deficient in deoxycytidine kinase activity, the Ara-C/8D clone, is a clonal derivative of an hypoxanthine-guanine phosphoribosyltransferase-deficient parent CEM cell line originally isolated in semi-solid agarose containing 8µM arabinosylcytosine. The Ara-C/8C and TUB-4D cell lines are cross-resistant to a spectrum of cytotoxic nucleosides to which parental and Ara-C/8D cell are sensitive.
