RESUMO

We tested the ability of sequences in the long terminal repeat (LTR) of a mink cell focus-forming (MCF) murine leukemia virus to function as an enhancer in a cell-type-specific manner. In a stable transformation assay, the MCF or Akv LTR and the simian virus 40 enhancer had similar activities in murine fibroblasts. In contrast, the MCF LTR had a significantly greater activity in murine T lymphoid cells than did either the simian virus 40 enhancer or the Akv LTR.
